The rotating cylinder manufacturers

Electromagnetic valve electrical signal is input signal and output the power source of the actuators with hydraulic oil, therefore, especially suitable for large thrust, large travel and high precision control applications. In large power plant, in order to obtain greater thrust, in main steam control system such as the frequently used. Compared with pneumatic actuator, hydraulic actuator with hydraulic mechanism, so it is of greater thrust or torque. But require more complex hydraulic system of hydraulic oil system and line control, such as control of the hydraulic oil temperature, pressure, etc, also need to supplement the cycle of oil and oil. Compared with the pneumatic piston actuator, hydraulic actuator adopts hydraulic cylinder instead of cylinder, because the hydraulic oil has incompressibility, therefore, the response speed can reach lOOmm/s, is faster than a pneumatic piston type actuators, accurate positioning precision pressure reducing valve stroke, high control precision, Level 5) , it can be a long ( Up to lm) , output torque, Up to 60000 nm) , export thrust large ( Up to 25000 n) 。 Hydraulic actuators will enter a standard current signal into the mechanical energy of the motor and hydraulic oil as working medium, through the power element ( Such as hydraulic pump) Converts the mechanical energy of the motor of the hydraulic oil pressure can, and the pipeline and control components, with the aid of actuators to hydraulic energy into mechanical energy, drive the valve stem completes the movement which the linear or rotary cylinder Angle. Therefore, it is the rapid response of electric actuators and piston actuator thrust, etc. But by using the hydraulic oil, oil leakage problems such as system
