Hydraulic valve in a hydraulic system is more critical parts. Its running state is directly related to the stability of the hydraulic system, therefore, the maintenance and repair of hydraulic valve is particularly important. With the hydraulic system life cycle becomes longer, the probability of failure of hydraulic valves will also rise, which more or less normal operation of the hydraulic system will bring a certain impact. In general, the hydraulic valve failure, mainly due to wear, cavitation and other reasons, resulting in the hydraulic valve body and the valve tolerances between the gap is too large, causing the body's own internal leakage phenomenon occurs. A long time, it will make the hydraulic valve pressure locking bad, causing the entire hydraulic system pressure instability, and the occurrence of hydraulic valve failure. For the existence of such failures hydraulic valves, can be repaired. General repairs following two methods: a. Cleaning of the hydraulic valve body. Hydraulic valve with a long time inside some more or less accumulation of dirt and impurities, for the purpose of cleaning the body is to carry out these dirty cleaned. In the process of cleaning the more critical aspect is the rough wash and two sperm washing. Rough cleaning is to remove the valve body and the valve open to the two parts of the tray on the washing tank, heat soak, and then into the cleaning tank of compressed air through the bottom, use the bubble agitation, remove the valve cover and the spool on the dirt. Sperm washing is positioned high pressure cleaning with a cleaning solution, and then hot air drying. Two. For the body and surface wear larger spool hydraulic valve, multi-use parts matching combination repair method. This repair method has the advantage of ensuring that reasonable tolerances between body and spool match. When a damaged hydraulic valve between the valve body and valve wear too large, a long time drain fault occurs. Then you can just factory according to the hydraulic valve body size, actual size, and choose a factory-fresh little difference in body size to replace the valve, so that you can ensure that the hydraulic valve uniform at work running it.
