Self-made progressive cavity pump structure analysis progressive cavity pump is a commonly used positive displacement pump, which can effectively convey high-viscosity liquids.
It is characterized by simple structure, reliable operation and stable transmission flow.
Below I will make an in-depth analysis of the structure of the progressive cavity pump and expand some related content to make the article richer.
1.Pump body: The pump body of a progressive cavity pump is usually composed of two metal shells, which are the pump head and the pump tail.
The pump head part contains the feed port and the oil pressure chamber, and the pump tail part contains the discharge port and the suction chamber.
The metal housing has excellent corrosion resistance and high strength, which can ensure the long-term stable operation of the pump.
2.Screw: The screw is the most critical component of the screw pump, which is composed of multiple spirals, usually two or three spirals.
The material of the screw is usually made of high-strength stainless steel to ensure its wear resistance and corrosion resistance.
A spiral hollow cylinder is formed between the helix lines of the screw, which has good sealing performance.
3.Pump core: The pump core is the core component inside the progressive cavity pump, which is composed of a rotor and a stator.
The rotor is the core part of the screw, and the stator is the housing that sits around the rotor.
The gap between the rotor and stator is very small, allowing for good tightness and flow control.
Through the rotational motion of the screw, the working principle of the positive displacement pump is formed in the pump core, so that the liquid can be conveyed.
When the pump core rotates, the volume of the oil pressure chamber of the pump head part gradually increases, and the liquid is sucked in;
As the pump core rotates, the volume of the oil pressure chamber gradually decreases, pushing the liquid out of the discharge port at the end of the pump.
One of the advantages of the progressive cavity pump structure is the ability to convey highly viscous liquids, because the screw pump has very good sealing properties and can effectively resist the leakage of liquids.
The progressive cavity pump also has self-priming ability and can work normally at low liquid levels, which greatly facilitates its use.
In addition to the above structural analysis, the progressive cavity pump also has some related content worth noting.
For example, progressive cavity pumps have a wide range of applications and can be used in petroleum, chemical, food, pharmaceutical and other industries.
Screw pumps are widely used in the petroleum industry to transport ** and heavy oil;
In the chemical industry, progressive cavity pumps can be used to convey high-viscosity chemical liquids;
In the food and pharmaceutical industry, progressive cavity pumps can convey thick food and pharmaceutical liquids.
As a positive displacement pump, the progressive cavity pump has a simple and reliable structure and stable flow delivery capacity.
Through an in-depth analysis of the structure of the progressive cavity pump, we can better understand its working principle and characteristics.
The wide range of applications of progressive cavity pumps in various industries further proves their superiority in liquid transfer.
