description

The JMV147 closed-loop piston travel motor pump is a classic mid-large displacement heavy-duty model of the JMV series, widely applied to 25–35 ton large excavator travel systems. Facing frequent medium-heavy load start-stop, complex road vibration impact and long-term continuous high-temperature oil scouring in daily engineering construction, the JMV147 pump is prone to friction pair wear, surface scratch and gradual performance attenuation, resulting in reduced motor volumetric efficiency, insufficient heavy-load traveling power, delayed linkage response and slight walking deviation and jitter. JMV147 hydraulic pump spare parts adopt targeted heavy-duty optimization for large-tonnage engineering harsh working conditions. Core friction pair components are made of high-rigidity alloy steel matrix + high-density wear-resistant copper alloy composite material, with excellent wear resistance and impact resistance. The cylinder block undergoes integral heat treatment and multiple stress relief treatments to eliminate internal processing stress, matched with ultra-precision mirror lapping to form stable micron-level clearance fit with the valve plate, effectively restraining internal leakage growth under long-term high-pressure and high-temperature operation.

FAQ

  • Q1: What typical faults can JMV147 pump spare parts solve?
  • A: It effectively solves common heavy-duty faults of JMV147 travel motor including increased internal leakage, insufficient heavy-load walking torque, weak climbing ability, sluggish hydraulic response, unilateral speed deviation, walking jitter, abnormal noise and high-temperature oil seepage and leakage.
  • Q2: What equipment is JMV147 suitable for? A: Mainly applicable to 25–35 ton various brands of large construction and light mining excavators, perfectly matching original JMV147 heavy-duty travel motor assembly and supporting system parameters.
  • Q3: How to choose single parts or full overhaul kit?
  • A: For motors with short usage time and only partial slight wear, choose single-piece replacement; for motors with long-term heavy construction operation, obvious power attenuation and overall component aging, it is recommended to replace the full rotating group kit to restore original heavy-load performance.
  • Q4: What are the key points for JMV147 motor overhaul?
  • A: Clean internal wear powder and impurities thoroughly, replace all aging high-temperature and high-pressure seals, strictly control friction pair assembly clearance and flatness fitting, and conduct walking test and debugging after assembly to ensure synchronous left and right speed and stable torque output.
  • Q5: How to extend the service life of JMV147 travel motor?
  • A: Keep hydraulic oil clean and replace filter elements regularly; avoid long-term overload and over-speed operation; control system oil temperature to prevent oil deterioration and seal aging failure.
