hydraulic piston pump assembly

When Elephant Hydraulics provides solutions to customers for hydraulic problems, it is found that many customers have small problems such as wear and tear of some parts after long-term use, because many customers contact and Remote guidance, and then disassemble and replace the parts by yourself, which leads to misunderstandings in many places, so many users have problems in the method of installing hydraulic piston pump, which makes it impossible to use normally, so we share 6 correct methods of hydraulic piston pump assembly for you.

1. Regardless of whether the piston pump is seated or flanged, the root support should have sufficient rigidity.

2. The coaxiality of the drive shaft (for example, the motor shaft) and the pump shaft (for example, the oil pump shaft) should be less than 0.05mm, which can be adjusted with a dial indicator.

3. Because the hydraulic piston pump bears radial load at some time, try not to use belts, chain gears, etc. to drive the pump.

4. The distance between the center height of the oil pump installed on the oil tank and the oil level should not exceed 500mm, and the suction pressure should be (-16.7~-0.5)×10Pa. Otherwise, it is difficult for the hydraulic piston to self-prime, resulting in cavitation. High vacuum will cause wear on the suction components and create problems such as noise and vibration.

5. It is not recommended to install a filter on the upper suction pipe. The outlet of the hydraulic piston pump is only installed with a pipeline oil filter with a filtration accuracy of 25Mpa, and the hydraulic pump needs to be installed near the oil tank, and the oil suction method should be used backwards.

6. When installing the connector to the hydraulic plunger pump, do not knock the pump shaft vigorously. There are often machined threads on the pump shaft that are specially used to install the connector, which can be used to push the connector to the pump shaft.

The above is the correct operation method of some frequently used operations. If you need a more detailed explanation, please contact our staff for a more specific problem description, and they will try their best to solve it for you. If your piston pump encounters an irreparable failure and needs to be replaced directly, please visit the website of Elephant Fluid Power's store https://elephant-power1.en.made-in-china.com/, except for the integral hydraulic piston In addition to pumps, Elephant also provides parts for piston pumps, where you can find everything you need and can get it at a cheaper price.
