Avoid weak foundation of hydraulic pump installation. The installation foundation of the hydraulic pump must be firm, that is, the installation foundation has proper independence and rigidity. Because there is not only a coaxial requirement between the hydraulic pump and the shaft of the prime mover but also usually need to be connected by an elastic coupling. If the installation foundation of the hydraulic pump is not strong, the foundation will be deformed after assembly. <\/p>\n\n\n\n

At the same time, affected by the mechanical vibration of the prime mover and the hydraulic pump, it is easy to cause the minimum requirement of coaxial between the hydraulic pump and the prime mover’s shaft to be lost, resulting in damage to the hydraulic pump. Hydraulic pump installation<\/p>\n\n\n\n

The coaxial of the hydraulic pump shaft and the prime mover shaft is out of tolerance after assembly, and the hydraulic pump should be prohibited from running. After assembly, it is found that the coaxial of the hydraulic pump shaft and the prime mover shaft are out of tolerance. The shaft seal of the pump will be damaged if the magnetic hydraulic pump is prematurely pressed, and the force of the relevant parts in the pump will become very bad, leading to the premature damage of the hydraulic pump. Hydraulic pump installation<\/p>\n\n\n\n

The hydraulic pump and the prime mover output shaft should be connected by a flexible coupling. It is strictly forbidden to install a pulley or gear to drive the hydraulic pump on the hydraulic pump shaft. If a pulley or gear must be used to connect the pump, a pair of supports should be added. To install the pulley or gear, the coaxial error between the support and the pump shaft should not be greater than 0.05mm. Hydraulic pump installation<\/p>\n\n\n\n

Avoid using the front-end cover of the ordinary motor to support the hydraulic pump cantilever. Ordinary motors, such as B35 motors, although the front end cover can support the hydraulic pump cantilever, can only be used when the hydraulic pump cannot be supported by other means, and it is best used for fixed equipment, such as engineering Mechanically because there is usually a certain amount of vibration, it will cause certain damage to the front end cover of the motor. Hydraulic pump installation<\/p>\n\n\n\n

Avoid insufficient rigidity of the hydraulic pump support frame (bent plate). The hydraulic pump can be installed with a support or a flange. The pump and the prime mover should use common base support, and both the flange and the base support should have sufficient rigidity. Note: Plunger pumps with a flow rate greater than (or equal to) 160L\/min should not be installed on the fuel tank. Hydraulic pump installation<\/p>\n\n\n\n

Avoid installing hydraulic pumps with painted shells below the oil level in the oil tank. When a hydraulic pump with a painted shell is installed below the oil level in the oil tank, even if it is oil-resistant paint, due to the wide variety of hydraulic oil and paint with different properties, over time, it will often cause chemical changes and lead to deterioration of the paint. In addition, paint peeling occurs from time to time, which can cause hydraulic system failures. Hydraulic pump installation<\/p>\n\n\n\n

The oil suction pipe should be as short, straight, large, and thick as possible. The oil suction pipe should generally be equipped with a coarse filter with a nominal flow rate not less than twice the pump flow rate (the filtering accuracy is generally 80 ~ 180um). The oil suction pipe port and the oil return pipe port of the oil pump must be less than 200mm from the lowest oil level of the oil tank. <\/p>\n\n\n\n

Special attention: An oil filter is not allowed to be installed on the suction pipe of the plunger pump. The diameter of the stop valve on the suction pipe should be one block larger than the diameter of the suction pipe. The length of the suction pipe is L2500mm, and there are no more than two pipe elbows.<\/p>\n\n\n\n

When piping, avoid excessive oil suction resistance of the hydraulic pump. As shown in Figure 1-2(a), there are several sections of hard pipe, shut-off valve, filter,\u00a0and a section of hose on the suction line of the hydraulic pump, which require more pipe joints. It can be seen that the total pressure loss on the pipeline will be very large. If the local flow area of the pipeline becomes smaller when piping, the problem will be more serious. Hydraulic pump installation<\/p>\n\n\n\n

It is easy to cause insufficient oil suction of the hydraulic pump\u00a0until the hydraulic pump is damaged, it is good as shown in Figure 1-2(b). If the hose and the shut-off valve are indispensable, their diameter should be appropriately increased to ensure the suction pressure required by the hydraulic pump. Hydraulic pump installation<\/p>\n\n\n\n

The oil suction port of the hydraulic pump should not be connected with dumplings. Due to the limitation of the structure, the oil suction resistance of the dumpling pipe joint is much greater than that of the straight-through pipe joint, which will cause noise caused by insufficient oil suction of the pump and reduce the service life of the hydraulic pump, as shown in Figure 1-3.

Avoid using soft rubber or plastic pipes as the suction pipe of the pump. Use a softer tube such as a plastic tube or a rubber tube as the suction pipe of a hydraulic pump. Of course, it is used when the pressure in the suction pipe is lower than the atmospheric pressure. Under the action of the peripheral atmospheric pressure, the oil suction pipe may be deformed to greatly reduce the actual flow area, increase the oil suction resistance, and affect the normal operation of the pump.

The drain pipe of the hydraulic pump should be directly connected to the oil tank, and the backpressure of the oil return should not be greater than 0.05MPa. Hydraulic pump installation<\/p>\n\n\n\n

\u00a0In the use of the pressure in the casing and the drainpipe, the casing of the hydraulic pump sometimes has to bear a certain pressure. Due to the limitation of the oil seal (rotary seal) and the flange gasket on the pressure compensation variable mechanism, the pressure in the shell should not exceed 0.16\uff5e0.2MPa, and the drainpipe cannot be connected to other oil return pipes and must be returned to the oil tank separately. Hydraulic pump installation<\/p>\n\n\n\n

Avoid connecting the drainpipe of the hydraulic pump to the main return pipe of the system. As shown in Figure 1-4, the pressure in the main oil return pipe of the hydraulic system is generally higher than the discharge pressure of the hydraulic pump and is sometimes accompanied by pressure shocks. If the drainpipe of the hydraulic pump is connected in parallel with the main oil return pipe of the system, it is obvious that the pressure in the pump body is required to be higher, and it is also affected by the pressure shock of the main oil return pipe of the system.

Avoid connecting the drain pipes of several hydraulic pumps in parallel to form an equal-diameter pipe before passing to the oil filling tank. The drain pipes of several hydraulic pumps are connected in parallel to form an oil pipe, and this pipe is the same diameter as the drain pipe on the pump body, so when the hydraulic pump is working, the oil pressure in the pump body will be higher. When several hydraulic pumps are working at the same time Even more so. <\/p>\n\n\n\n

High pressure in the pump body will damage the shaft seal, and will also adversely affect the oil suction of the hydraulic pump. The pipes connecting the drain pipes of the hydraulic pumps in parallel should have appropriate diameters and lead them to the oil tank separately. Hydraulic pump installation<\/p>\n\n\n\n

Avoid that the highest part of the oil pipe connected to the drain port on the hydraulic pump body is lower than the axis of the pump. The oil drain contained in the oil drain cavity of the hydraulic pump body also plays the role of lubricating the movement of the pump shaft. If the highest part of the oil drain pipe is lower than the axis of the pump, the hydraulic oil in the oil drain port is completely drained for lubrication. The effect will be invalid. Hydraulic pump installation<\/p>\n\n\n\n

Avoid connecting the leaking oil pipe of the hydraulic pump to the suction pipe of the pump. Because the external leaking oil pipe of the hydraulic pump discharges hot oil, it is easy to increase the temperature of the pump body, which is very detrimental to the service life of the pump. In addition, in some cases, the external leakage oil pipe of the pump is connected to the suction pipe of the pump, which may cause the pump body to not be filled with the required hydraulic oil, which is even more unfavorable, as shown in Figure 1-5.
