Hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or swing motion). It is simple in structure and reliable in operation. When it is used to realize reciprocating movement, the reducer can be avoided, Hubei Hydraulic cylinder And there is no transmission clearance, smooth movement, so it is widely used in various mechanical hydraulic systems. Output force of the hydraulic cylinder is proportional to effective area of the piston and pressure difference on both sides; The hydraulic cylinder basically consists of cylinder barrel, cylinder head Hubei Hydraulic cylinder manufactor The piston and piston rod, sealing device, buffer device and exhaust device are composed.

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. Hubei Hydraulic cylinder Through quenching and tempering treatment, the comprehensive mechanical properties of the cylinder piston rod with good strength and toughness matching were obtained. Hubei Hydraulic cylinder manufactor 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.

The connection between the oil cylinder and the actuator and the connection between the oil cylinder and the oil pipe cannot be the same, because there must be some differences between the connection between the oil cylinder and different products. In addition, during the use of the oil cylinder, it is necessary to avoid scratches, Hubei Hydraulic cylinder Because if this problem occurs, it will affect the normal use of the oil cylinder. At present, there is no software for designing hydraulic cylinders, but there are design standards for hydraulic cylinders, and it is necessary to design hydraulic cylinders according to these standards. So far, Hubei Hydraulic cylinder manufactor There is no software for designing hydraulic cylinders, but there are design standards for hydraulic cylinders.

The two lips of the seal have two contact circumferential surfaces. Whether the force on the inner and outer circumferences is evenly distributed means that the force on the two circumferences cannot be zero. If the force on a certain point is zero, the shaft seal has inner and outer lips, Hubei Hydraulic cylinder The outer lip is installed in the groove to contact the outer wall, and the inner lip is in contact with the piston rod surface. Both lips have an interference amount, which is equal to the generation of two contact circumferential surfaces, that is, the generation of two circumferential rebound forces. How to determine the magnitude of the circumferential force? Both the inner and outer lips of the seal have two chamfers. Since the interference of the same inner and outer lips is certain, Hubei Hydraulic cylinder manufactor The angle of the chamfer determines the size of the circumferential area of the inner and outer contact of the two lips.

Because the hydraulic cylinder must bear a great pressure, the heavier the load, the greater its pressure will be. Therefore, the maintenance of the hydraulic cylinder is the most important part of the maintenance of the entire hydraulic system. The hydraulic cylinder is the heart of the hydraulic system. It is difficult to repair a heart problem, so the maintenance of the hydraulic cylinder should be careful. first, Hubei Hydraulic cylinder Rust prevention is required. Because the piston part of the hydraulic cylinder will extend out of the cylinder in the working state, it will naturally suffer from oxidation Hubei Hydraulic cylinder manufactor The erosion of acid gas requires us to apply proper amount of grease to protect it.

Before removing the hydraulic cylinder, depressurize the hydraulic circuit. Otherwise, when the oil pipe joint connected with the oil cylinder is loosened, Hubei 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. Hubei Hydraulic cylinder manufactor 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.
