One of the executive components of the hydraulic system is the hydraulic cylinder, the main work of the hydraulic cylinder is responsible for the function of linear lift or expansion. Its features are light weight, large power, simple structure, convenient maintenance, small inertia, frequent commutation, easy to achieve remote control. Hydraulic cylinders have been widely used in many types of machinery.
The following is a double-acting single piston hydraulic cylinder as an example to analyze the hydraulic energy into the linear motion of the piston mechanical energy. The so-called input hydraulic energy refers to the flow and pressure of the input liquid, and the output machinery is the speed and traction of the piston when it moves in a straight line. All these parameters are dependent on the change of working volume to achieve, so that the hydraulic cylinder is a volumetric actuator.
In order to meet the needs of the various mechanical, hydraulic cylinder has a variety of different structure and performance, according to the hydraulic pressure methods can be divided into single acting cylinders and double-acting hydraulic cylinder, according to their structural characteristics can be divided into piston hydraulic cylinder and piston hydraulic cylinder, telescopic hydraulic cylinder and the oscillating hydraulic cylinder, is called a hydraulic cylinder, equivalent to the heart of the elevator, hydraulic oil cylinder that we how to v?
First, rust prevention: because the piston part of the hydraulic cylinder will extend out of the cylinder in the working state, it will naturally receive the corrosion of acid gas oxide, which requires us to give him the right amount of grease for protection, so as to prevent the piston as a load-bearing part from being eroded and may break during work; Second out to replace the hydraulic oil: for use for a long time, one will have a foreign body into the hydraulic oil cylinder, this will increase friction in the use of imagination, in addition, the hydraulic oil also has the certain service life, no oil change for a long time will damage or erosion of the hydraulic oil cylinder, hydraulic cylinder to use longer on the hydraulic oil cylinder to control the speed of the job properly, not more than 2 m/s, it can prolong the service life of hydraulic oil cylinder, the other in order to protect the institutions and be on the safe side, the internal installation buffer device is very effective for the protection of the hydraulic oil cylinder.
Because the hydraulic oil cylinder to bear a lot of pressure, the heavier load, the pressure will be greater, therefore, do a good job in the maintenance of hydraulic oil cylinder is the maintenance of the hydraulic system is the most important one annulus, and the hydraulic oil cylinder is equivalent to the hydraulic system of the heart, heart problem is very difficult to repair, so the maintenance of the hydraulic oil cylinder is to be especially careful.
