How to Repair Worn Gear Tooth Surfaces in Hydraulic Systems
In real hydraulic system operation, gear tooth wear is one of the most common causes of reduced pump efficiency, increased noise, and pressure instability. Proper evaluation and repair are critical to restoring pump performance. 1.Minor Surface Wear (Light Polishing Wear) Condition: Smooth surface / No deep grooves / Wear within allowable tolerance Repair Method: ✔ […]
Repairing a Gear Pump：What Are the Component Replacement Principles?
In practical hydraulic system maintenance, repairing a gear pump is not simply about replacing damaged parts. A scientific repair strategy ensures performance recovery, safety, and long service life. Below are the professional principles followed in industrial maintenance. 1. Replace as a Matched Pair Principle Gears, bearings, and wear plates must be evaluated as matched components. […]
Common Gear Pump Failures
Most gear pump failures are system-related rather than pump-related. Proper oil cleanliness, correct suction design, and routine inspection are key to long-term reliability. 1.Insufficient Pressure or Flow One of the most common gear pump problems in daily operation: Internal wear of gears and housing Excessive internal leakage Incorrect pump speed or oil viscosity Result: Reduced […]
