PCP Rotator and Stator

‌Sunrise Petro: A Pioneer in PCP Rotator and Stator Manufacturing in China

Screw pump is a commonly used equipment for fluid transportation, in which the stator and rotor are important components of the pump and play multiple key roles.

The stator and rotor of the screw pump produced by Sunrise have reliable quality and have been exported to multiple countries around the world for application in different oil fields.

Description

The stator is a key component of a screw pump and directly affects the lifespan of the downhole unit. The higher the quality of stator manufacturing, the longer the service life of the underground unit. The function of the stator is to provide a spiral cavity for rotor operation and liquid suction. Its structure is very simple, consisting of a steel shell and a plastic/rubber lining. The inner cavity has double helix, triple helix, quadruple helix, and even five helix and six helix. Under the same size, the more helices there are, the higher the pump displacement

The structure of the rotor is relatively simple, with the main body made of steel rods and generally coated with wear-resistant and corrosion-resistant chromium alloy material. Its function is to transmit power and form a sealing chamber by writing the stator.

The stator is an important component that is prone to damage in screw pumps. When designing and developing, it is necessary to consider the accuracy of the stator tooth profile curve and the correctness of material selection, which directly determines the length of stator life. Generally, when selecting a rubber stator, the hardness should be considered: the medium containing particles should be lower, and the pure and clean medium should have a higher hardness; Medium with lower viscosity may have a slightly higher hardness.

Function

Although there are various types of screw pumps, the main functions of their stator and rotor are the same

1. Collaborative work: The stator and rotor of the screw pump closely cooperate to form a pump chamber, which achieves fluid suction, compression, and discharge through relative motion. The shape and position of the stator play a crucial guiding role in the fluid transport process.

2. Wear and corrosion resistance: The stator is usually made of high-strength, wear-resistant, and corrosion-resistant materials to cope with corrosive media and particles that may exist in the fluid, ensuring the service life and performance of the stator.

3. Realizing the normal operation of the pump: The design and material selection of the stator directly affect the normal operation of the screw pump. The reasonable design of the stator can ensure the efficiency, stability and reliability of the pump, and ensure the efficient transportation of fluid in the pump.

4. Provide fluid seal: The gap between the stator and rotor is a crucial part of the fluid seal in the pump. The surface of the stator forms a moderate gap with the rotor, which can ensure smooth fluid flow and effectively prevent leakage, maintaining the sealing of the system.

5. Adjust the performance of the screw pump: The shape and position of the stator can affect the performance parameters of the pump, such as flow rate, pressure, etc. By designing the structure of the stator reasonably, the working performance of the screw pump can be adjusted to meet different fluid transportation needs.

6. Guidance and support function: The stator not only plays a guiding role in fluid transportation, guiding the flow of fluid, but also plays a certain supporting role in the rotor, maintaining the stable structure inside the pump.

7. Improving system efficiency: The role of the stator is directly related to the efficiency of the entire pump system. The reasonable design and selection of the stator can reduce energy loss, improve the transportation efficiency of the system, and reduce operating costs.

8. Adjusting the pump displacement: The shape and structure of the stator can affect the pump displacement. By adjusting the parameters of the stator, the pump displacement can be adjusted to meet different working conditions.
