Many hydraulic cylinders often work under harsh conditions. Therefore, when selecting a hydraulic cylinder, according to the working environment of the hydraulic cylinder, environmental factors such as dust, soil, sand, wind and rain, salt, radiation, and temperature need to be considered. In order to make the hydraulic cylinder work reliably, the hydraulic cylinder should have anti-rust, anti-traumatic, anti-dirt and anti-high and low temperature performance.
In places with humid air, especially when the hydraulic cylinder works in an environment attacked by wind, rain, sea water, etc., it is very susceptible to corrosion and rust. The hydraulic cylinder with anti-rust function should be selected accordingly. Anti-rust paint, electroplating and the use of corrosion-resistant materials such as stainless steel.
2. The surface of the piston rod is hardened
Some hydraulic cylinders have very bad external working conditions and have to withstand external blows. For example, the piston rod of the hydraulic cylinder of a shovel often collides with sand and gravel, resulting in marks. The piston rod or plunger of the hydraulic cylinder of the press should directly press the workpiece. At this time, the surface hardness of the piston rod should be increased. The main method is to do high-frequency quenching on the surface of the piston rod.
Because most hydraulic cylinders use nitrile rubber as seals, their working temperature cannot exceed the working temperature range of nitrile rubber. General hydraulic cylinders are suitable for working in the range of -10-+80 degrees, not exceeding -20-+105 degrees. The boundaries. Otherwise, when working at high temperature, it is easy to be glued and glued. After the hardness of the seal is reduced, the phenomenon of squeezing into the gap will be more serious, which will accelerate its damage and destroy the sealing effect.
