The plunger pump is an internationally renowned hydraulic brand with hydraulic pumps such as Rexroth, Vickers, Denison, etc. It has many advantages, but even if it is a plunger pump, it is inevitable that some accidents and problems will occur in daily use. Failure, before encountering a failure, the plunger pump should be checked and maintained regularly. At the same time, after a failure, it should be checked and diagnosed in a timely manner.

3. The compressed gas charged into the accumulator should be discharged first, and then the accumulator should be transported or disassembled.



4. If the gas pressure drops by more than 0.5MPa, check for gas leakage. When the gas is initially installed, check once a week and then once a month.

5. We need to know that inclined or horizontal installation will cause the airbag of the accumulator to contact and wear out the casing, which will affect the service life of the accumulator. Therefore, the accumulator is generally installed vertically with the oil port downward.
