Parker piston pump maintenance introduction: Parker Parker piston pump in the entire hydraulic system has a vital role, more and more industries using Parker's hydraulic pump, but many partners in the daily operation, do not know how to maintain and maintain our hydraulic pump, may have partners will ask, why do maintenance and maintenance? In fact, no matter what kind of product, it needs us to do a good job of maintenance, do a good job of each must
Parker Parker piston pump maintenance tips.
1. Selection of hydraulic oil varieties
(1) according to the working pressure of the hydraulic system selection: different working pressure environment on the hydraulic oil quality requirements are different, the system working pressure increases, the hydraulic oil is required to have anti-wear, oxidation resistance, anti-foaming and anti-emulsification and hydrolysis stability and other properties should be improved. At the same time, in order to prevent leakage caused by the increase in pressure, the viscosity of hydraulic oil should be increased accordingly; conversely, low viscosity hydraulic oil should be selected.
(2) according to the use of environmental temperature selection: in the high temperature environment or near the heat source operation of machinery, should give priority to the use of high viscosity (oil viscosity changes with the temperature, that is, viscous temperature) of the oil or flame-retardant oil; in the harsh working conditions of the occasion, in order to ensure the safety and reliability of the system, to use the viscous temperature characteristics, thermal stability, lubrication and rust and corrosion prevention performance of the fluid.
(3) according to the seal material selection: hydraulic device seal material and the system used in the fluid compatible, otherwise the seal in will appear expansion, shrinkage, erosion, dissolution and other phenomena, resulting in a decline in system performance, such as HM anti-wear hydraulic fluid and natural rubber, butyl rubber, vinyl rubber, silicone rubber and other poor compatibility, this point in the actual use is to pay attention to.
2. Operation requires good maintenance matters
1）Before starting each machine, first check whether the oil level in the tank reaches the specified oil level, if it is insufficient, add oil to the standard oil level, when refueling, choose the hydraulic oil of the appropriate brand number of this model in strict accordance with the provisions of the equipment manual or according to the relevant manual of equipment performance requirements; the higher the cleanliness of the hydraulic oil, the longer the service life of the hydraulic pump; before starting the machine, check whether all major components and solenoids are in the specified The original state, all please first return to the original state after the start
2）Regulate the working pressure and speed of the hydraulic system reasonably according to the design regulations and work requirements; it is strictly forbidden to work and regulate the pressure without a pressure gauge
3）If the machine is shut down for more than 4 hours, the hydraulic pump should be kept idling for more than 5 minutes before running again, and then work with pressure; pay attention to the system working condition frequently, observe the working pressure, speed, voltage, meter reading, and record on time
(4) regularly check the oil temperature of each operation, control at 35 ℃ ~ 55 ℃ is more appropriate, if the temperature is found to rise suddenly, should stop mechanical operation to identify the cause, and be discharged after the start of operation; such as a part of the hydraulic system failure, but also to maintain the stop and timely maintenance, do not run reluctantly, so as not to cause unnecessary accidents
(5) do a good job of regular inspection plan, check the pipe joints, flanges and other components to prevent vibration-induced loosening; keep the Parker piston pump hydraulic equipment clean, to prevent foreign pollutants into the tank and system
(6) the use of oil supply piston pump, in the use of 3000h, the operator needs to check the piston pump 1-2 times a day, check the contents include: hydraulic pump running sound is normal, such as the discovery of hydraulic cylinder speed drop or bogging phenomenon, should be disassembled to check the oil pump, check whether the impeller edge scratch phenomenon, the internal gear pump clearance is too large, etc.
(7) Parker piston pump bearing is an important part, need to ensure that the bearing does not appear clearance, otherwise it can not ensure that the internal clearance of the three pairs of hydraulic pump friction vice normal, but also will destroy the friction vice of the hydrostatic support oil film thickness, reduce the service life of the piston pump bearing; bearing the average service life of 10,000 hours, more than this value need to replace the new bearing
(8) when replacing the bearing, should pay attention to its bearing type, plunger pump bearings mostly use large load capacity bearings, it is recommended that zui good use of the original parts
The use of Parker piston pump length, and we usually do its maintenance and maintenance is inseparable, all people like Parker piston pump high efficiency, good performance, low noise, long life, do not know that there are many operators in the absence of correct use and maintenance of machinery, the use of time may not even half a year, this situation will not only affect the efficiency of the project, invisible for the enterprise to increase more More costs; all mastering the daily maintenance skills become particularly important.
In general, zui simple is also zui easy to cause damage to Parker piston pump is the cleanliness of the oil, quality and quantity of oil; many operations did not pay attention to this detail, this paper Parker piston pump maintenance tips also do not know once mentioned in the use of oil, oil into the foreign body or sand and other things, will cause direct damage to the friction side of the piston pump, must always Attention, as long as each part of the above, I believe that can largely extend the service life of Parker Parker piston pump and the use of efficiency, reduce the number of problems in operation, I hope to see this article of the partners thereafter can do a good job of daily maintenance, so that it creates greater value for themselves.
