CYD-8 Hydraulic Disc Spring Operating Mechanism(Complete)

1.The mechanism uses disc spring as energy storage medium, hydraulic oil as transmission medium, easy to obtain high pressure to make its structure small and compact.

2.Closing and closing operations rely on hydraulic transmission, operating noise is small, buffer smooth.

3.High operating power, high closing and closing speed, fast action and sensitive response.

4.Integrated piping design.

5.modular structure, no piping design, six modules with their own characteristics.

6.Complex structure manufacturing process, materials, processing precision requirements are particularly high.

7.Simple installation structure, the body and the hydraulic mechanism adopts direct connection mode.

Product Description

The main hydraulic components of CYD-8 series hydraulic disc spring actuator include combined disc spring, working cylinder, control valve, oil pump motor, energy storage cylinder, travel switch, safety valve, high-pressure oil drain valve, low-pressure oil tank, connecting seat and other components; adopting the disc spring as the energy storage component, the disc spring has excellent force characteristics, is not affected by the ambient temperature, the stored energy is large, and the force characteristics are smooth. Its structure adopts integrated module design, no pipeline connection. Adopting advanced sealing structure design, advanced dynamic and static sealing system and internal integrated hydraulic buffer system, the system has high pressure, small and compact structure, high operating power, stable and reliable performance. It is mainly suitable for high voltage and high current in 252kV-1000KV voltage level GIS and tank circuit breakers.
