The function of telescopic cylinder

The telescopic cylinder guides the cylindrical metal part in which the piston performs linear reciprocating motion. The working medium converts thermal energy into mechanical energy through expansion in the engine cylinder;the gas is compressed by the piston in the compressor cylinder And increase the pressure. Housings for turbines and rotary piston engines, etc.

How the telescopic cylinder works

The telescopic cylinder is composed of two or more piston cylinders. The inner hole of the piston rod of the previous stage piston cylinder is the cylinder barrel of the subsequent stage piston cylinder. A long working stroke can be achieved and the structural dimensions can be kept small when retracted. The extension action of the telescopic cylinder is carried out step by step. First, the largest diameter cylinder begins to extend with the lowest oil pressure. When it reaches the end of the stroke, the slightly smaller diameter cylinder begins to extend, and the smallest diameter final stage extends last. As the number of working stages increases, the diameter of the extended cylinder becomes smaller and smaller, and the working speed becomes faster.

Use and maintenance of telescopic cylinder

1. Before unpacking and installing the cylinder, you should check whether the components are damaged during transportation, whether the connecting bolts are loose, and whether the solenoid heads of valve components are damaged, and remove the protective caps. and protective oil, install and use according to the instructions.

2. When using the telescopic cylinder, care should be taken not to damage the surface of the piston rod and prevent damage to the rod end seal. Cylinder is leaking.

3. When installing and using the solenoid valve, special attention should be paid to the control voltage of the solenoid head. The allowable voltage fluctuation is -15~10%. When operating the solenoid valve with a manual knob, it must be ensured that the power supply is off to prevent damage to the solenoid valve.

4. When the system is running normally, check the working condition of the air filter and oil mist regularly, and drain the water and refuel in time.

5. When the telescopic cylinder manufacturer is not using it for a long time, it should pay attention to the minimum working frequency of 1 time/30 days.

6. Regularly add lubricating oil to the mounting parts connecting the middle swing shaft or tailstock shaft.
