Where is the sealing ring of the hydraulic piston pump? How to replace it

A、 Position of sealing ring for hydraulic piston pump The sealing ring of a plunger pump is usually located between the pump body and the inlet and outlet flanges of the plunger pump. The function of the sealing ring is to prevent medium leakage and pressure loss. Therefore, the sealing ring has a high frequency of use and wear, and requires regular maintenance.

B、 Steps for replacing the sealing ring of the piston pump 1. Prove that the plunger pump is in a normal shutdown state. 2. Disassemble the fastening nuts on the inlet and outlet pipelines and pump body, and remove the pump body. 3. Remove the sealing ring of the plunger pump, usually using pliers and a hammer, and gently tap to remove it. 4. Replace the new sealing ring and install it in the position of the sealing ring. 5. Restore the pump body and pipeline, and tighten the nuts. 6. Fill the liquid to the appropriate position, start the plunger pump, and check for leaks.

C、 Maintenance and upkeep of plunger pump sealing ring 1. Before operation, check the sealing ring for wear and deformation. 2. Regularly replace the sealing ring to prevent leakage and loss. 3. Use appropriate sealing rings and select materials that can adapt to the working conditions of the pump. 4. Avoid operational errors and unnecessary damage to the sealing ring. In short, the sealing ring of the plunger pump is an indispensable and important part of the plunger pump, and its position and replacement method need to be maintained reasonably. At the same time, the selection and maintenance of sealing rings also need to be taken into account to ensure the long-term normal operation of the pump.
