The role of the inlet valve actuator
The main function of the oil inlet valve actuator is to convert the control signal into physical motion, thus controlling the opening and closing of the oil inlet valve. In particular, the oil inlet valve actuator receives the signal from the control system, and drives the oil inlet valve to open or close according to the corresponding action by motor, pneumatic, hydraulic, etc., to realize the control of the fluid medium .
The inlet valve actuator plays an important role in the automatic control system. It can precisely control the opening of the oil inlet valve according to the instructions of the control system, so as to adjust the flow rate and pressure of the fluid. This control method is widely used in various industrial fields, such as petrochemical, water treatment, power industry, etc., which significantly improves production efficiency and system safety 12.
Different types of actuators have different working principles and characteristics. For example, the electric actuator drives the valve to open and close through the motor, which has high accuracy and reliability; The pneumatic actuator is driven by compressed air and has the advantages of fast response speed and simple structure. The hydraulic actuator is driven by liquid pressure and is suitable for occasions where large thrust is required. These characteristics make different types of actuators suitable for different application scenarios .
The working principle of the oil inlet valve
suction process : When the sucker rod moves up, the upper discharge valve is closed, the lower suction valve is opened, and the liquid in the well will be sucked into the pump barrel.
discharge process : When the rod moves down, the lower suction valve is closed and the upper discharge valve is opened. Under the pressure of the plunger, the liquid in the pump barrel is lifted to the oil pipeline on the ground.
repeat process : This process is repeated over and over again to achieve continuous pumping.
