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. […]
How to Eliminate Oil Trapping in Hydraulic Pumps
Method 1: Add Pressure Relief Grooves Relief grooves are machined on side plates or valve plates to connect trapped chambers to low-pressure zones. This allows oil to escape gradually and prevents sudden pressure build-up. Method 2: Optimize Port Timing & Geometry Proper inlet and outlet port timing ensures trapped oil chambers are released at the […]
