Solutions to design and manufacture defects of hydraulic system

Solutions to design and manufacturing defects:

1. The choice of hydraulic components often plays a decisive role in the leakage of hydraulic systems. This determines that our technical personnel in the design of new products, the improvement of old products, the selection of cylinders, pumps, valves, seals, hydraulic accessories, etc., should be based on the principle of choosing the best, the best in the selection of cheap prudently, have a comparison.

2, reasonable design of the installation surface and sealing surface: when the valve group or pipeline is fixed on the installation surface, in order to get a satisfactory initial seal and prevent the sealing parts from being squeezed out of the groove and being worn, the installation surface should be straight, the sealing surface requires finishing, and the surface roughness should reach 0.8μ M, the flatness should reach 0.01/100mm. There should be no radial scratches on the surface, and the pretightening force of the connecting screw should be large enough to prevent surface separation.

3, in the process of manufacturing and transportation, to prevent the key surface bump, scratch. At the same time, the assembly debugging process should be strictly monitored to ensure assembly quality.

4, the leakage of some hydraulic system do not lose heart, must be eliminated.
