How to control quality in wholesale hydraulic components？

How to control quality in wholesale hydraulic components? The components should be selected according to the pressure and use occasions. The tubing must have sufficient strength. The inner wall should be lubricated, clean, free of sand, rust, and oxide skin. For the long-term storage pipe, it should be pickled, completely cleaned, washed, and washed before processing. Check. Yunnan hydraulic components should install hydraulic cylinders firmly. In order to prevent thermal expansion, when the stroke is large and the temperature is high, one end of the cylinder must be kept floating.

The sealing ring of the hydraulic cylinder should not be too tight, especially the U-shaped ring, to avoid excessive resistance. A complete hydraulic system consists of five parts, namely power equipment, performance equipment, control and conditioning equipment, auxiliary equipment, and liquid media. Because of its large transmission power, easy transmission and equipment characteristics, hydraulic pressure is widely used in industrial and civil industries. The function of the fulfillment components (hydraulic cylinder and hydraulic motor) of the hydraulic system is to convert the pressure energy of the liquid into mechanical energy, and then obtain the required linear reciprocating motion or rotary motion. The function of the power equipment (hydraulic pump) of the hydraulic system is to convert the mechanical energy of the prime mover into the pressure energy of the liquid.

Hydro-pneumatic transmission has many outstanding advantages, so it is widely used, such as general industrial plastic processing machinery, pressure machinery, machine tools, etc.; construction machinery, construction machinery, agricultural machinery, automobiles, etc. in walking machinery; steel industry Metallurgical machinery, lifting equipment, roll adjustment equipment, etc.; flood control gates and dam equipment for civil and hydraulic engineering, river channel lifting equipment, bridge operating mechanisms, etc.; turbine speed control equipment for power plants, nuclear power plants, etc
