2, when used, must not add partial load or overload, to prevent the risk of damage to the jack. When there is a load, should not remove the quick connector, to prevent accidents and damage to the
parts.
3, new or long set of hydraulic jacks, since there are more air cylinders memory, when started, the rod may appear tiny breakaway phenomenon, can the hydraulic jack load reciprocating motion 2-3
times to exclude cavity air. long idle jack, do not work long-term because the seals caused by hardening of the seal, thus affecting the life of hydraulic jacks, hydraulic jack when not in use so
a month to load hydraulic jack 2-3 times reciprocation.
4, after the high-pressure pipe factory 105Mpa test. However, due to the hose easy to aging, so the user must always check, usually for six months, frequently with those of three months. 87.5Mpa
pressure test with inspection and, if blasting, bump leakage and other phenomena can not be used.
In what ways can use to find the cause pump failure
For hydraulic pumps and other related equipment have application users may understand, after a period of time we can not avoid it will be some failures, large and small, and therefore have an
impact on our work, found the problem to be solved problem, we were able to find the reason for this from the following three points:
1. Check hydraulic boom cylinder internal leakage situation. The easiest way is to raise the boom to see if it is not obvious free fall. If the fuel tank drops significantly demolition
inspection, such as worn seals should be given replacement.
2. Check the operating valve. First clean the safety valve, check valve body is not worn, such as wear and tear should be replaced. If there is still no change after the valve is installed, and
then check the case of control valve spool wear, the gap is generally limits the use of 0.06mm, badly worn should be replaced.
3, the measurement of the pressure of the hydraulic pump. If the pressure is low, then make adjustments, plus the pressure is still not tune up, then pump heavy wear.
Above that these, I hope we can gain, you want to know more about the knowledge of the hydraulic pump can often focus our company's News!
Structure This section describes various types of axial piston pump
??????Axial Piston Pump
Axial piston pump reciprocating piston or plunger moving direction and parallel to the central axis of the cylinder piston. Axial piston pump is the use of volume changes and the drive shaft
parallel to the reciprocation of the plunger in the plunger bore produced to work. High volumetric efficiency, smooth operation, flow uniformity, high working pressure, low noise advantages, but
more sensitive to contamination of the hydraulic fluid, the structure is more complex, higher cost.
??????Hydraulic piston pump
After relying on pneumatic hydraulic piston pump hydraulic oil tank after each start the machine, be sure to use other hydraulic stains box arrival pressure, to operate machinery. Straight axis
swashplate piston into two kinds of pressure from the sucking oil type. Most oil pressure hydraulic pump use of air pressure tank, but also with its own hydraulic cylinder to pump up the oil
provided the oil inlet pressure of the oil. Self-suction-type pump self-absorbing capacity is very strong, and do not need external oil supply.
??????Straight axis swashplate piston pump
Straight axis swashplate piston into two kinds of pressure from the sucking oil type. Most oil pressure hydraulic pump use of air pressure tank, but also with its own hydraulic cylinder to pump
up the oil provided the oil inlet pressure of the oil. Self-suction-type pump self-absorbing ability is very strong, no external oil supply. Rearward pressure hydraulic oil tank after each start
the machine, such as hydraulic stains box must use air pressure, to operate machinery.
??????Radial piston pump
Radial piston pump with flow valves can be divided into the axial flow of two categories. Valve with flow radial piston high failure rate, low efficiency shortcomings. Because the characteristics
of the radial pump structure, axial flow of radial piston pump axial piston pump than the impact resistance, long life, high control accuracy.
Piston Pump
??High-pressure pump maintenance let me tell you that
????High-pressure pump life long or short, and the usual maintenance, hydraulic oil quantity with quality, cleanliness and other oil related. To prevent the oil particles cause wear on the piston
friction pairs, etc., is also an effective way to extend the life of the high-pressure pump. Replacement parts in the maintenance should try to use 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, like a short-term savings cost, but thus brings out hidden
dangers, but also may lead to greater use of high-pressure pumps harm.
????Make use of the high-pressure fuel supply pump, after the use of 3000h, operators need to check the high pressure pump 1-2 times a day to check the pump running sound is normal. Found
cylinder speed drops or stuffy car, 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.
????The most important parts of the high-pressure pump bearing, if the bearing clearance occurs, it can not guarantee normal internal pump three pairs of friction pair gap, but
also undermine the friction pair hydrostatic bearing oil film thickness, reduce the use of piston bearing life. According to information provided by the manufacturer of the pump, the average life
of the bearing is 10000h, more than this value will need to be replaced with new port. Dismantled bearings, no professional testing equipment is unable to detect bearing clearance, but to use
visual, such as found in the roller surface scratches or nue to use.
