Valve plate face wear paver repair prices, pull grooves valve plate using a hydraulic motor, such as JMDG type, NHM type, etc., when the valve plate face wear paver repair factory, especially pulling deeper grooves, internal leakage increases, the speed is not enough; another paver repair company, pressure compensating clearance mechanism failure also caused this phenomenon. You should grinding or polishing the end face of the port plate. After the damaged piston ring seal on the plunger paver repair damaged, causing the seal between the piston and the cylinder bore failure, internal leakage increases. Time to replace the seals. Suction chamber pressure and the pressure oil chamber is inconsistent, both rely on the end face of the gear cover; the gap between the crests and the reciprocal movement of the pump seal. So this is very important to both the size of the gap, the gap big, liquid back severely, reduced efficiency, or even not work; the gap is small, the high friction, even jammed the motor burned out gear. This indicates that these two gaps need to ensure the machining accuracy and mounting accuracy.
