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, Tangshan Hydraulic system It permeates all fields of the national economy, including agricultural machinery, automobiles, light textile, shipbuilding, petroleum, aviation and machine tool industries, Tangshan Hydraulic system manufactor Hydraulic technology lists some application examples of hydraulic and pneumatic transmission.
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, Tangshan Hydraulic system 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, Tangshan Hydraulic system manufactor In the whole process, the hydraulic cylinder converts hydraulic energy into mechanical energy.
For the selection of hydraulic cylinder, the hydraulic cylinder will be selected according to the inner diameter, stroke, operating pressure and installation type during the selection of hydraulic cylinder. In fact, in addition to these, we should pay attention to the following points. First, when the hydraulic cylinder is loaded and then the actuating speed reaches a certain standard, Tangshan Hydraulic system Hydraulic cylinder with buffer device must be used. Or when the speed reaches a higher speed, a deceleration valve must be installed outside the hydraulic cylinder; Secondly, carefully select hydraulic oil and oil seal. Oil seals of different materials are selected for different hydraulic oils, Tangshan Hydraulic system manufactor To ensure the service life of the hydraulic cylinder.
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, Tangshan Hydraulic system 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 Tangshan Hydraulic system manufactor The erosion of acid gas requires us to apply proper amount of grease to protect it.
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, Tangshan Hydraulic system 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, Tangshan Hydraulic system manufactor If you choose cheap oil cylinder rashly, the quality cannot be guaranteed, which will lead to endless troubles.
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, Tangshan Hydraulic system 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: Tangshan Hydraulic system 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.
