It is suitable for hydraulic transmission of construction machinery, lifting, transportation machinery and mining machinery. Hydraulic transmission principle - oil is used as working medium, Zhangjiakou Hydraulic cylinder The movement is transmitted through the change of sealing volume, and the power is transmitted through the pressure inside the oil. 1. Power part - converts mechanical energy of prime mover into pressure energy (hydraulic energy) of oil. For example: hydraulic pump. 2. Executive part - converts the oil pressure energy input by the hydraulic pump into the mechanical energy driving the working mechanism. For example: hydraulic cylinder, hydraulic motor. 3. Control part - used to control and adjust the oil pressure Zhangjiakou Hydraulic cylinder Manufacturer Flow rate and flow direction. For example: pressure control valve, flow control valve.
The oil cylinder shall be assembled in a special workshop or assembly area, and the temperature shall be kept at 20~250C, Zhangjiakou Hydraulic cylinder Manufacturer It shall be far away from the tuyere, dust and cutting area, with fresh air, no dust and no noise; Avoid direct glare. The assembly room shall be equipped with installation platform, sufficient working position apparatus, assembly turnover vehicle Zhangjiakou Hydraulic cylinder Lifting and hoisting equipment and the following special basic equipment. a: Cylinder loader; b: Another cylinder cleaning machine is used to heat and clean another part; c: Pressure test equipment, used for pressure test of oil cylinder; d: The air duct is used to clean and dry the other parts after cleaning.
Before removing the hydraulic cylinder, depressurize the hydraulic circuit. Otherwise, when the oil pipe joint connected with the oil cylinder is loosened, Zhangjiakou Hydraulic cylinder The high-pressure oil in the circuit will be ejected rapidly. When the hydraulic circuit is depressurized, first loosen the hand wheel or pressure regulating screw at the overflow valve to unload the pressure oil, and then cut off the power supply or power source to stop the hydraulic device. During unloading, prevent damage to the thread at the top of the piston rod, the thread at the oil port, the surface of the piston rod, the inner wall of the cylinder liner, etc. Zhangjiakou Hydraulic cylinder Manufacturer In order to prevent the piston rod and other slender parts from bending or deformation, the skid shall be used to support and balance during placement.
If the piston rod of the hydraulic cylinder is not treated in time after being pulled, the normal use will be affected if it is light, and the operation will not be possible if it is heavy. The repair methods we adopt are local polishing to repair light draw marks, welding and manual polishing to repair heavy draw marks. Zhangjiakou Hydraulic cylinder Through quenching and tempering treatment, the comprehensive mechanical properties of the cylinder piston rod with good strength and toughness matching were obtained. Zhangjiakou Hydraulic cylinder Manufacturer The purpose of surface hardening is to obtain high surface hardness to support the chromium plating layer on the surface, so as to improve the wear resistance and corrosion resistance of the piston rod.
