 1. Ensure the quality of hydraulic components procurement 

  In the procurementprocess of hydraulic system components, it is necessary to carefully check thequality of purchased parts such as pumps, valves, hydraulic cylinders andhigh-pressure hoses; during the transportation and storage process, the hydraulic ports of all components must be equipped with sealing plugs to prevent contamination. Intrusion. 

  2. Reasonableassembly

  Before assembly,all hydraulic components and accessories must be carefully cleaned; after cleaning, all the ports should be closed with plastic tape; the hydraulic components should be assembled using the “dry assembly” method, ie the partsafter cleaning should be dry after the surface is dry. If it is assembled, it is forbidden to use iron tools to strike. If you need to tap, you can use wooden hammer, rubber hammer or copper hammer; do not wear gloves whenassembling, and do not use fiber fabric to wipe the component mounting surfaceto prevent fiber. Class substances invade the valve; when the assembled hydraulic parts are not assembled, use plastic tape to block all ports.

  3. Guarantee thequality of hydraulic oil

  Hydraulic oilshould be added according to the manufacturer's specifications, do notarbitrarily change the grade. The hydraulic oil must be sampled and inspectedat the factory. After the inspection, it must be filtered before it can be injected into the fuel tank. Hydraulic oil should maintain a certain degree of cleanliness, usually with solid particle pollution level, moisture content,viscosity change, total acid value, etc. as the main test indicators.

  4. Clean andreplace the oil filter in time

  The oil filter installed on the suction port of the hydraulic pump and the oilinlet of the important hydraulic components should be cleaned or replaced asscheduled to effectively remove the chips and large particles in the hydraulic oil to avoid the stuck, scratched and blocked hydraulic components. phenomenon.
