How To Prime A Hydraulic Piston Pump

The A10VSO series piston pump is a popular series of Elephant Hydraulic Power products, and many pieces have been sold since it was put on the shelves. Why is it so popular? Take this series of A10VSO71DFR/31R-PPA12N00 piston pumps for example, the advantages are very obvious.

This series of hydraulic piston pumps is specially designed by Elephant Hydraulics for open circuit hydraulic drive. The flow of the pump is proportional to the speed and displacement of the pump, and the displacement can be adjusted steplessly by adjusting the inclination of the swash plate. It is also equipped with a load-sensing pump for applications where flow is required in the hydraulic system. Axial piston pump spare parts adopts swash plate design and plane flow distribution. Through shaft drive, both front and rear pumps can be connected in series. In addition to these, they have a very desirable power-to-weight ratio and low noise performance.

But I found that many people find it difficult to start the hydraulic piston pump correctly after buying it, which will directly lead to the piston pump not being able to play the advantages of our product itself. Elephant suggests that after installation, the pump must be filled with clean hydraulic oil (note that it must be clean oil) through the drain port on the pump casing before starting for the first time, otherwise it cannot be started. After installing the pump and motor and connecting the system correctly, inject clean oil into the pump or motor, remove the upper oil drain pipe, and tighten the joint after seeing the oil flow out. Next, turn the coupling by hand to check whether the pump shaft rotates evenly, whether the installation is firm and not loose, whether the two couplings are concentric, etc. It is also necessary to check whether the rotation direction of the pump motor is consistent with the specified rotation direction. When the pump is started, the start button must be started and stopped several times to confirm that the oil flow direction is correct and the pump sound is normal, and then start continuously. After the new pump is used for one week, all the oil in the oil tank should be filtered and the oil tank and filter should be cleaned, and then the oil should be replaced every 3 to 6 months according to the system working environment load, and the oil tank should be cleaned once. Because the hydraulic piston pump itself is susceptible to contaminants due to its structure, these basic points are what everyone needs to do, so that their parts can be used longer and are less likely to be damaged.
