 If you walk inside the main valve spring soft or broken, or the valve is stuck, are likely to cause lower oil pressure, appear to walk deviation. Check, walking the main valve to measure the oil pressure, normal if 32.5Mpa. If you walk the main valve damage variable pump · refinement, to be replaced or repaired. My unit PC200 excavator has twice appeared to walk deviation variable pump · Specialist, are due to damage caused by walking the main valve. Therefore, in the event of failure to walk deviation, you should first consider whether to walk the main valve is damaged variable pump · care to avoid detours. Variable pump and variable motor speed control loop is often applied to the composition of the volume of open and closed-circuit hydraulic system. Volume loop speed control circuit by changing the pump or hydraulic motor to achieve the speed of displacement. Its main advantage is a small power loss (no overflow losses and throttle loss) and the working pressure varies with the load, so that a high efficiency, low temperature of the oil, especially for high-speed, high-power systems.
