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

Fluid cleanliness. The cleanliness of the system oil will have a very important impact on the hydraulic cylinder. Hydraulic shock and vibration hydraulic cylinders will be affected by the performance of components, pipeline and medium characteristics, etc., which will be accompanied by hydraulic shock and vibration. Generally speaking, if the oil temperature is too high or too low, Zhejiang Hydraulic cylinder manufactor Will have a great impact on the working efficiency of the hydraulic cylinder. If the oil temperature of the hydraulic cylinder is too high or too low, the physical and chemical properties of the medium will change, Zhejiang Hydraulic cylinder As a result, the viscosity of the working medium decreases or the possibility of leakage increases.

For the same hydraulic cylinder on the Internet, some manufacturers quote more than 1200, some more than 1600, some about 1800, and even some about 3000. This situation makes the purchasing manufacturers feel puzzled and very difficult. Most manufacturers have limited procurement funds, Zhejiang Hydraulic cylinder Therefore, if you want to achieve the predetermined purchase goal, you need to choose the hydraulic cylinder with high cost performance ratio, good quality and low price. However, the price gap of hydraulic cylinders in the market is staggering, Zhejiang Hydraulic cylinder manufactor If you choose cheap oil cylinder rashly, the quality cannot be guaranteed, which will lead to endless troubles.

The diameter of the oil unloading hole of the hydraulic cylinder is too large, which directly affects the service life of the rubber seal ring on the piston. Because the piston moves back and forth, Zhejiang Hydraulic cylinder When the rubber seal ring on the piston passes through the oil discharge hole, the rubber's own elasticity expands to the oil discharge hole, and the oil discharge hole edge and the piston seal groove edge shear the rubber seal ring. At the same time, China has the advantages of strong market demand and low cost, and is expected to become the center of gravity of the world's hydraulic industry and oil cylinder industry in the future. The hydraulic cylinder is a very important part of the hydraulic machinery and plays an executive role in the entire hydraulic machinery, Zhejiang Hydraulic cylinder manufactor In the whole process, the hydraulic cylinder converts hydraulic energy into mechanical energy.

How to install and fix the hydraulic cylinder? There are two common ways to fix the hydraulic cylinder: the first is the square hydraulic cylinder fixed on the B plate, and the hydraulic cylinder needs to be positioned on the B plate. The second is a round hydraulic cylinder fixed on the ejector plate. It should be noted that the thimble plate locking screw needs to be added next to the hydraulic cylinder, and the force at this position is large, Zhejiang Hydraulic cylinder Prevent tension deformation. Another point is to inscribe words on the hydraulic cylinder, and write down the stroke of the hydraulic cylinder for easy verification. To correctly install the sealing device at each position of the hydraulic cylinder: Zhejiang Hydraulic cylinder manufactor When installing the O-ring seal, pay attention to its installation direction to avoid oil leakage due to installation. Its lip should face the oil chamber with pressure.

Compared with mechanical transmission, hydraulic cylinder transmission is a new transmission form. Hydraulic transmission has a history of more than 200 years since the birth of hydraulic press, but hydraulic transmission has been going on for many years. Especially after the 1960s, with the development of atomic energy science, space and hydraulic technology, Zhejiang Hydraulic cylinder It permeates all fields of the national economy, including agricultural machinery, automobiles, light textile, shipbuilding, petroleum, aviation and machine tool industries, Zhejiang Hydraulic cylinder manufactor Hydraulic technology lists some application examples of hydraulic and pneumatic transmission.
