Our website: www.pepfluid.com http://www.pepfluid.com/t6c-vane-pumps-and-cartridge-kits/ Process / method Conclusion: After the above discussion, reached the following conclusion ① total stroke reciprocating plunger L is constant, the resolution by the cam lift. ② plunger fuel supply amount per cycle depends on the size of the fuel supply stroke, stroke oil from the camshaft control is variable. ③ oil supply start time does not vary with changes and itinerary changes. ④ roll plunger may change oil end time, and then change the amount of oil. 3. Domestic Series Injection Pump Domestic Series Piston mainly A, B, P, Z and Ⅰ, Ⅱ, Ⅲ number series. Series is based on a single-cylinder diesel power plans to plead not the same amount of oil to the piston stroke, the pump cylinder base distance and structural type of foundation, and then leave with a different standard diameter of the plunger, constitute several species in a varying the amount of oil fuel pump inside the work cycle, to the satisfaction of the needs of various diesel engines. Domestic series fuel injection pump operation principle and structure of the same type of base to A-type pump as an example describes the structure and operation principle of a plunger-type fuel pump. Some piston pump consists of four components: cylinder, fuel scheduling organization, the organization and the pump drive Copper sleeve cylinder piston inserts, you can choose to replace copper sleeve approach equipment. First, a group of at plunger rod diameter trimmed to standard together, then 1000 # sandpaper polished than the outer diameter. Copper cylinder equipment sets three ways: (A) loading or copper cylinder plus warm jacket cryogenic kneading, interference device; (B) adopt a Loctite adhesive with the equipment, which we approach begged copper coat the outer diameter of the outer grooves; (C) bore tapping, threading copper sleeve outer diameter after coating Loctite glue, screw device. Piston is a major equipment hydraulic system. It relies on the plunger reciprocates in the cylinder, so that the volume of the cavity sealing operation is changed to the end of the suction pressure oil. Piston pumps with a rated pressure, compact structure, high efficiency and flow conditioning facilitation benefits, it is widely used in high pressure, high flow and traffic demand conditioning occasions, such as hydraulic machines, construction machinery and ships in. Axial piston pump is to use the drive shaft parallel to the plunger in the plunger bore volume change occurred in reciprocation for the job. Since the plunger and the plunger hole are circular parts, can reach very high precision machining and cooperation, thus high volumetric efficiency, smooth operation, flow uniformity, low noise, operating pressure senior interests, but for the hydraulic oil pollution the more active, the structure is more messy, higher cost. Melting contact information and copper cylinder sleeve, the device measures as follows: (A) selection of ground rods, craft mechanical way grinding or amend the bore; (B) the choice of coordinate boring, boring scratch the cylinder bore; (C) Selection Reamer correction cylinder bore. (3) selection of "look engineering technology" approach as follows: (A) plating techniques: the plunger outer layer of hard chrome plating; (B) electrical brush technique: Brush the plunger outer wear-resistant materials; (C) thermal spraying or electric arc spraying or spray: Spray carbon martensite wear-resistant materials; (D) Laser cladding: the plunger outer cladding alloy powder by high hardness. (4) no copper sleeve cylinder bore of the cylinder material are mostly ductile iron, prepared amorphous thin film or coating on the cylinder wall. Since the cylinder bore wall with this exceptionally substance, so it tune constituting the hard - hard matching friction deputy

Oil poured into the tank through a filter is necessary. Filtration is often used once a month, the fuel tank should be regularly cleaned. Should generally adhere to the oil level in the tank is about 85%, and should be insufficient to replenish, replenish oil should the original pump oil numbers are the same. Oil fuel tank shall normally be 10 ~ 40 ℃ is appropriate, should not be used at negative temperature. ? Second, the tubing pressure to avoid bending at work and cohesion pump jack tank should adhere to clean, when not in use with a screw dam, avoid sediment into the oil pump and nozzle revealed jack to use nuts sealed to prevent dust, miscellaneous substance into the machine. After daily use, the pump should wipe, eradicate grease consider oil on copper silk. ? Third, the pump should not work under overload safety valve shall be additional hydraulic device to adjust the pressure, prohibit arbitrary adjustment. ? Fourth, grounding power, chassis ground wire is necessary to view the line insulation condition only after the trial work. ? Five former high-pressure pumps work should release all the oil control valve, then start the pump, empty load of work to be normal, then closed return valve, the stem gradually screwed into the oil, increasing the load, and pay attention to the gauge Pointer is not normal. ? Sixth, the pump should stop the job first return valve gradually loosened until the gauge gradually return to zero, before breaking jack tubing connector nut. Removable tubing or pressure gauges and other prohibited when the load. ? Seven, cooperation dual effect of oil pump jack in order to use the two together duplex oil pump is appropriate. ? Eight, oil resistant rubber tube high voltage necessary work shall not exceed the maximum hydraulic pressure of the hydraulic pump extra or actual job. Tubing length less than 2.5m. When a femoral artery and two pump jack, tubing standard should work together. ? Precautions Removable tubing or pressure gauge prohibition load ? When the job, under the injection pump camshaft cam and the plunger stretched spring effect, forcing the plunger for the upper and lower reciprocating motion, and then complete the mission oil pump, oil pump process can be divided into the following three periods. Into the oil process When the cam bumps turn over some, in effect stretched spring force, the piston moves downward, the plunger upper space (called pumping chamber) occurred vacuum, when the end face of the plunger on the piston sleeve into the hole open, the full oil passage in the upper body pump diesel into the pumping chamber through the hole, the plunger is moved to the lower dead point, into the oil is completed. Fueling process When the camshaft to the cam roller raised some jacking body, the plunger spring is stretched tight, the upward movement of the plunger, the fuel pressure, a through hole flow back into the fuel injection pump some oil chamber upper body. When the plunger cover the top hole of the upper edge of the sleeve to travel, because the plunger and the sleeve with a small space (0.0015-0.0025mm) pump oil chamber of the plunger at the top of the oil into a sealed chamber, column Cypriots continued to rise, active hydraulic pump oil chamber increased, pumping pressure> outlet valve spring force + high pressure hose stretched remaining pressure, open the valve, high pressure diesel fuel through a valve into the high pressure tubing, after injection It is injected into the combustion chamber. Back to oil process Plunger up oil, when the uplink to the chute (stop for the edge) on the plunger back hole on the sleeve and connected, low pressure oil pump oil chamber and then the head of the plunger hole and radial holes and chutes exchange, hydraulic suddenly reduced, the oil valve in the stretched spring force effect active closed, continuous supply. Thereafter the plunger but also upstream, when the cam bumps turn over some, under the effect of stretched spring plunger and down. At this time began the next cycle.

Diesel high-pressure pump is not a normal job, working on all diesel has a crucial impact. Diesel engine can not start the diesel engine can not start the trouble can not reason is that low pressure oil to the high pressure fuel supply. 1, the oil in the air, to obstruct the fuel into the high-pressure pump oil chamber. Place a long time on a diesel engine, it is a normal appearance. Its approach is to release the high pressure pump bleed screw, hand pump to the high pressure pump oil, wipe clean the air, and then tighten the bleed screw. If effective, it is possible to loosen the filter pipe joints deflated, then bleed vent screw. 2. Low oil blocked, so no high pressure fuel pump low pressure oil chamber oil. The site of obstruction main pump oil inlet filters and filter elements, blocking reason is Dirty, attributed to normal skills situation changed, if found should immediately eliminate or replace. 3, the low-pressure pump to the high pressure fuel supply can not. Pump piston severe wear or damage, spring or other parts may cause damage to the appearance of such problems, identify the cause be replaced. 4, the high-pressure fuel supply pipeline or a road link portion severe leak. Check tubing connector is not loose and tubing is not damaged, loose to tighten, to replace damaged. Our daily test axial piston pump, the press does not load, empty load test can be run properly, when we put the object, but no pressure can not operate, this phenomenon with the axial piston pump wear components are influences. ????Axial piston pump inside the port plate and the plunger, in the case of high-speed operation, the plunger and the cylinder with high clearance requirements, produce flow and pressure, if after a long run-in with the gap enlarged, it will cause internal leakage , which can not reach the corresponding flow and pressure; in addition, in the case of the port plate rotates at high speed, with the entry of the passage of time and impurities directly wear, then not produce pressure, flow generated directly through the gap and return port directly to tank vent. Above it is an axial piston pump manufacturer to introduce you to factors that can not operate normally, hoping to help everyone better solution. When we experience this, be sure to check the wear of each part, timely check and replace, guaranteed to work properly. Whether using a manual pump, or the use of other related products, no matter how high its quality, its use for some time, inevitably there will be some failures, large and small, which have an impact on our work, then In order to use a manual pump can proceed smoothly, how to prevent these failure it? ??????Xiao Bian for you on this issue, we first need to regularly check and replace aging or damaged oil seal or "O" ring sealing gasket; in addition to the manual replacement of worn hydraulic gear pump or pump bushings, wear light in flat end mill will be smooth. Its flatness tolerance 0.03mm; the end face of the sleeve is less than the plane manual pump body (normal is less than 2.5 ~ 2.6mm), such as ultra-poor should be the next sleeve plus 0.1 ~ 0.2mm copper to compensate for installation When put on the rear axle load should be set; if you can do these points compared with its applications will play help. ???????Jiangsu Hengli Hydraulic Co., Ltd. is specialized in producing electric hydraulic pumps and various hydraulic equipment business.

When replacing the bearing, it should pay attention to is the original English words bearing the mother and model, piston bearing most receiving large load bearing capacity, it is best to purchase the original factory, the original specifications of the product, if the exchange another brand, you should seek advice on bearing history lookup swap staff, in order to allow precision grade and load bearing capacity can be maintained. ????Piston length of life, and the usual maintenance, number and quality, such as hydraulic oil clean-up of oil-related. Stop the oil particles to cause piston friction pairs wear, but also extend the life of the piston favorable way. Replacement parts in the repair should as far as possible with the original production of parts that sometimes imitation parts than other more expensive, but the quality and stability is better, if the purchase price of cheap imitation parts, feeling short term cost savings, but the resulting potential problems, but also on the use of piston cause more damage. ????Oil in the form of a straight axis swashplate piston pump based ????Straight axis swashplate piston pump into pressure from the sucking oil type and type two. Most oil pressure hydraulic pump with a pressure tank there, but also comes with its own pump to pump up the oil cylinder oil inlet supply pressure of the oil. Since self-absorbing capacity type hydraulic pump super suction, no outside help to supply. ????After the required pressure of the hydraulic oil tank, after each time you start the machine, you have to wait to use the pressure of hydraulic stains box before they can start operating machinery. Once the hydraulic reservoir pressure is insufficient, served as the machine will pump and slip inside the whip phenomenon caused by the pull-off, then the cause is not normal wear and tear the body board and return the pump platen. After using the charge pump supply piston pump 3000h, operators need to check piston 1-2 times a day to check the pump operation is not a normal sound. If the cylinder speed drops or stuffy car situation, you should check the disintegration of the charge pump, check the impeller edge if there are scratches phenomenon, the internal gear pump gap is too big. For self-suction-type piston pump, the hydraulic oil tank must not fall below the lower limit of the oil standard, to maintain a sufficient amount of hydraulic oil. Cleanliness of hydraulic oil higher, longer pump life. View high-pressure pump job before the job is as follows: Before 1 primary electric pump equipment using first check the voltage status, and plugs, sockets to see is not connected; 2, one end of the high-pressure pipeline, links on the electric pump device connector, the other end connected to the needs of the things; 3, pay attention to both ends of the connector before use is not locked into place, it is necessary to move to the top of what the joint force, without relaxing the conditions screwed jacket nut. If not locked in place there will be the appearance of oil can not pass, and then will attack without the operation of the machine status. Before use it is necessary to view the ministries is not normal. Use should be in strict compliance with the rules of the main parameters, avoid ultra-overload, or when lifting height or lifting tonnage in excess of the rules, electro-hydraulic jack unit will attack a serious oil spill.

Market conditions Piston pumps and other pumps in shipbuilding, oil exploration, truck cranes and other widely used. 2008 ship production reached 15,000 tons, accounting for 21% of the number dwt world market, 2015 will become the world's largest shipbuilding country. To ensure the normal navigation or mooring boat, crew and passengers to meet the daily needs of each boat must be equipped with a certain amount of, can play a relevant role in marine mining, marine pump is one of the important auxiliary equipment. According to incomplete statistics, in various ship auxiliary machinery and equipment, and the total number of all types of marine pumps for different purposes, accounting for about 20% -30% of the total amount of machinery and equipment of ships, marine pump prices in the marine equipment costs the proportion is relatively large. Of the total cost, the marine pump about 4% to 8% of the total cost of the ship equipment, under normal circumstances. Marine pump purchase a medium-sized vessels of up to 10 million yuan or more. ?Diesel high-pressure pump to adjust the fuel supply timing ????Diesel exhaust temperature, whether rough work, eat a load capacity of size, mobility, economy and a number of factors, such as quality and sophistication ventilation, turbocharger performance, fuel injector, cylinder and piston rings wear, the timing and the supply of high-pressure pumps, fuel quality and the like. When the diesel engine performance slip, but exclude the impact of other factors, it would be necessary for high-pressure pumps and reasonable adjustments. Of course, the need to be checked before adjustment. Check the method varies by model, pump type to another. We have Maoyou common law, light law and notation. ?????Mao law. Maoyou method is suitable for any model or type of oil pump timing checks. Removing either a cylinder pressure tubing connected to the high-pressure pump outlet valve, the high pressure pump and into the pipeline system filled with fuel. Slow disk drive, when the oil began to write down the flywheel transient fluctuation scale, that is, the cylinder fuel supply time, repeated (at least three times) and averaged, that is the cylinder injection timing. That method of measuring fuel supply advance angle. ?????Photopheresis. Large end section back to the hole injection pump, if the sleeve motivated, back hole of equal height, remove the screws on the corresponding pump. With the light back to the hole and screw hole cover moments, remember the oil supply from the moment of the flywheel scale. ?????Notation. Some of the high-pressure pumps in the pump and the pump column are engraved with a horizontal line, plate car, as long as the two lines is the oil agreement in time, read from the flywheel dial. ?Improve fuel pressure of the injection to achieve the best atomization, high-pressure pump main purpose is as a jack, upsetting head, pinch the power source machine, embroider machine hydraulics. ????High-pressure pump installation sequence: In the high-pressure pump installed in the process, in order to avoid the debris to fall into the machine, all the units should cover the perforations. The crew on the buried anchor bolts, based on the base and intermediate base with a pair of wedge pad for correction. Proofreading pump shaft and motor shaft concentricity, on the road linking the outer circumference of the shaft, you can have 0.1 mm deviation; two coupling plane gap should ensure that in 2 to 4 mm, (a small pump to take a small value) gap to uniform, tolerance 0.3 mm. After the connected piping and determine the motor direction of rotation, connect the coupling, and aromatic again continue proofreading concentric shafts. After the unit trial run 2 to 3 hours, do a final check, if no adverse phenomenon, is considered qualified to install. In the commissioning process, check the bearing temperature and vibration are as follows: Loosen the coupling large, with a horizontal instrument were placed on the electric oil pump shaft and the base, by adjusting the wedge pad, correction unit level, tighten the bolt appropriate to Anti-around. In order to prevent pipeline debris into the pump, to the newly installed pipeline should be installed in the pump glue filter, the effective cross-section should be greater than 2 to 3 times the suction pipe section. ??The main component is a piston pump bearing, if the bearing clearance occurs, you can not ensure normal internal pump three pairs of friction pair gap, but also the destruction of each friction pair hydrostatic bearing oil film thickness, so that the piston pump bearing reduced service life. According to information provided by the manufacturer of the pump, even bearing service life of 10000h, above the top of this he will need to exchange a new port value. Dismantled bearings, no professional testing equipment is unable to detect the bearing clearance, can only adopt the visual, such as roller scratched or discolored appearance of situation, it is necessary to replace.

(2) Check the plunger deputy with the situation. The plunger tip is inserted into the plunger comprising a tilt of about 60 °, if the plunger can slow the decline in its role as a good fit. (3) Check the plunger seal deputy. Hold the plunger sleeve, two fingers to block the plunger tip and the side of the inlet. Pull the plunger with the other hand, feel a greater attraction, relax plunger is retracted immediately situ, indicating piston secondary seal is good, or to replace the piston pair. (4) Check the oil pressure valve annulus vice is not worn or injuries have stepped phenomenon, when necessary, should be replaced. (5) check out the situation with the deputy of the oil valve. Use your fingers to block the oil valve under the hole, with the other fingers to gently press down the valve when the valve finger from the upper end of time, it can automatically spring back into place, it indicated that the valve secondary seal is good, otherwise should replace the oil valve deputy. (6) Check quite cylinder. Standard fuel pump body and the very cylinder gap between the 0 ~ 0.03mm, such as more than 0.2mm, it should replace the parts. Gap (7) Check the plunger flange and the control sleeve between the grooves, should be 0.02 ~ 0.08mm, such as more than 0.12mm, you must replace the control units. Electric pumps are providing pressurized fluid to the hydraulic drive a hydraulic components, is a type of pump. Electric hydraulic pump function is to power machine (such as an internal combustion engine and electric motor, etc.) of the mechanical energy is converted to pressure energy of the liquid. Output flow can be adjusted according to need is called a variable pump, flow can not be adjusted is called a metering pump. Electric hydraulic pump system often used gear pumps, piston pumps and pump three blades. Gear pumps: smaller, simpler structure, for the cleanliness of the oil is not critical, cheaper; however unbalanced shaft by force, badly worn, leaking large. Vane pumps: vane pump into a double-acting and single acting pumps. The pump flow evenly, smooth operation, low noise, operating pressure and volumetric efficiency is higher than a gear pump, the structure is more complex than the gear pump. Use hydraulic tank The important role of the hydraulic oil tank in the hydraulic system for the separation of oil, heat the oil contained in the air and eliminate foam. Choose to use the tank first thing to consider its capacity, general mobile equipment take 2 to 3 times the maximum pump flow rate, fixed equipment to take 3 to 4 times; Second, consider the oil tank when the system is all hydraulic oil tank may not extend below the minimum oil level when the oil level after retracting the cylinder must not exceed the maximum oil level; and finally consider the tank structure, the traditional fuel tank separator and precipitated dirt can not play the role of a vertical bulkhead should be installed along the longitudinal axis of the tank . Leave gaps between the separator tank at one end and the end plate on both sides of the separator space communication, the hydraulic pump oil inlet disposed at one end on both sides of the separator is not connected, so that the oil into the oil and return the distance between the farthest, hydraulic tank up some more cooling effect.
