Cylinder in the course of the hydraulic oil should be changed regularly, the filter cleaning system to ensure cleanliness and prolong life. Each time you use should be fully extended commissioning of five full-retracted stroke and then load operation. Why do this? This can drain the air from the system, preheat the systems, the system can effectively avoid the presence of air or water roller hydraulic maintenance, resulting in a gas explosion in the cylinder block (or scorching) phenomenon roller hydraulic service unit, it will damage the seals, causing the fuel tank vent failure. Pump noise is inherent in the original pump manufacturing technology has not yet reached the "robustness" requirement. Work on the pump, the pump shaft per rotation roller hydraulic repair factory, each pump piston are made only once the suction pressure of the oil into the circulation. Hydraulic roller plunger suction pressure maintenance organizations to complete the assignment process oil, when the rotation after the transition to the drain region on the cylinder plunger bore suck oil from the oil suction port plate on the window of time, full of low-pressure oil the plunger bore to the instant high-pressure oil drain valve plate on the window inside before turning (Figure 1, with Japan's Kawasaki K3V pump valve plate, for example), high-pressure oil discharge of oil from a window of the second ` Pre boost hole and triangular groove by the plunger into the cylinder bore to increase the hydraulic cavity formed intrusion traffic impact (see Figure II left) Xi'an-hydraulic-repair | hydraulic maintenance roller | roller hydraulic service from Xi'an Xianyang Cheng through hydraulic maintenance Limited.
