Stainless steel sludge horizontal screw pump

Stainless steel sludge horizontal screw pumpThe hydraulic drive device is composed of a prime mover, a hydraulic motor, and a hydraulic transmission part. Its advantage is that it can achieve low-speed start-up and is used for the extraction of high viscosity and high sand content crude oil; The speed can be adjusted arbitrarily; Due to the installation of a hydraulic anti reverse device, the reverse speed of the pumping rod has been slowed down. Its disadvantage is that it is difficult to insulate hydraulic components and pipelines on the ground during cold seasons, and the price is relatively high, making it difficult to manage.

① The main function of a gearbox is to transmit power and achieve first level deceleration. It transmits the power of the motor from the input shaft to the output shaft through gears, and the output shaft is connected to a light rod. The light rod then transmits the power to the rotor of the downhole screw pump through a pumping rod. In addition to transmitting power, the gearbox also transfers the axial load of the sucker rod to the Christmas tree;

② The motor is the power source of the sludge screw pump well, which converts electrical energy into mechanical energy. Generally, explosion-proof three-phase asynchronous motors are used;

③ The function of dynamic sealing at the wellhead is to prevent well fluid from flowing out and to seal the wellhead;

④ The function of the square card is to connect the output shaft of the gearbox with the light rod.

Stainless steel sludge horizontal screw pumpThe working components are eccentric screws (rotor) and fixed bushings (stator).

Due to the special geometric shapes of these two components, they form separate sealed chambers, and the medium flows uniformly in the axial direction. The internal flow velocity is low, the volume remains constant, and the pressure is stable, so there will be no vortex or agitation. The output pressure of each stage pump is 0.6MPa, the head is 60m (for clean water), and the self-priming height is generally 6m. It is suitable for conveying media with a temperature below 80 ℃ (special requirements can reach 150 ℃).
