Hydraulic Shock Absorber Switching Closing Oil Buffer for Vs1 Vacuum Circuit Breaker

Hydraulic Shock Absorber Switching Closing Oil Buffer For VS1 Vacuum Circuit Breaker  

Oil buffer is a kind of buffer used in vacuum circuit breakers at home and abroad. After development and improvement, it has become a new type of localized buffer in this series. It runs on the principle of storing oil and generating buffer force through a small oil circuit. It is made of a special formula mixed with hydraulic oil and high-quality precision parts. When the ejector rod is subjected to a huge impact force, the oil will produce great damping through the small oil circuit. , to achieve the purpose of buffering. Suitable for quick stops, especially as accessories for quick stops of rotating bodies.

Working principle
When the piston rod is impacted, the piston rod drives the piston to squeeze the hydraulic oil in the inner pipe. After the hydraulic oil is pressurized, it is discharged one by one from the oil discharge holes of the inner pipe, and part of the discharged hydraulic oil returns to the inner pipe through the oil return hole. , and the other part enters the pressure accumulating sponge.
After the external force disappears, the spring quickly pushes the piston rod to reset, negative pressure is formed in the inner tube, the check valve opens automatically, the hydraulic oil quickly returns to the inner tube through the opened check valve, and the buffer returns to its initial state, waiting for the next action.
The hydraulic shock absorber of Liyond company is to stop the moving object smoothly according to the above principle.

Features
It has the characteristics of small size, light weight, convenient installation, beautiful appearance, reliable performance, short stroke of micro buffer, and wide range of available speeds.

Use
Oil buffer is an ideal buffer element for vacuum circuit breakers and other products, and has been widely used in various vacuum circuit breakers such as ZN85.
