Causes and Solutions for Oil Leakage in High-Pressure Plunger Pumps

High-pressure plunger pumps are significant in industrial machinery, but oil leakage can occur. Here's an analysis of the causes and solutions:

1. Worn or Damaged Oil Seals: Continuous use, high oil temperature, abnormal pressure, and impurities cause wear. Replace with quality seals carefully and monitor temperature and filter oil.

2. Improper Fit between Plunger and Cylinder: Plunger wear or cylinder damage increases clearance. Grind or replace the plunger and repair or replace the cylinder. Ensure proper lubrication.

3. Loose Connections and Seal Failure: Bolts loosen and gaskets age or damage. Tighten bolts and replace gaskets regularly.

4. Faulty Check Valve Sealing: Seal surface wear and impurities affect sealing. Clean or replace check valve parts. Maintain and clean valves.

5. Cracks or Porosities in Pump Body: Casting defects or external impacts cause issues. Repair minor ones and replace them if cracked. Avoid impacts and control pressure.
 

Users can enhance equipment performance and reduce costs by understanding and addressing these. Regular maintenance is crucial.
