Hydraulic valve in a hydraulic system is more critical components. The quality of its operating status 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 the hydraulic valve will rise, which will run more or less normal hydraulic system some impact. Generally, hydraulic valve failure, primarily due to wear, cavitation and other factors, with the hydraulic valve clearance tolerances between the valve body and the valve body is too large, resulting in leakage occur within the body itself and so on. A long time, it will make a bad pressure hydraulic valve lock, causing pressure on the entire hydraulic system is unstable, and the hydraulic valve failure. The presence of such a fault for a hydraulic valve, can be repaired. There are roughly two repair methods: a. Cleaning the hydraulic valve body. Hydraulic valve with a long time inside more or less steeped in some dirt and impurities, for the purpose of cleaning the body to carry out these dirty cleaned. In the process of cleaning the two areas is more critical rough cleaning and finishing washing. Coarse wash is open to the demolition of the two parts in the valve body and the cleaning tank tray with heat soak, and then pass into the compressed air to clean the bottom of the box, using bubble agitation, remove the valve cover and dirt on the plug. Sperm washing is used to locate high-pressure cleaning fluid to clean, and then hot air drying. Two. For the degree of wear of the valve body and the surface of the larger hydraulic spool valve, multi-use combination of repair parts matching method. The advantage of this method is that it can ensure the maintenance of tolerance reasonable match between the body and the spool. When a damaged hydraulic valve between the valve body and the valve wear through the large, long time to drain fault occurs. Then you can just based on body size hydraulic valve factory, choose a practical size and body size difference is not just the factory to replace the valve, so that you can ensure that the hydraulic valve operation even at work.
