The screw self-priming pump is a very practical device that can transport various viscous liquids from one place to another. This type of pump has the advantages of high viscosity and high flow rate, which is very suitable for industrial applications. Next, we will introduce the working principle and advantages of the screw self-priming pump in detail.
The working principle of
1. screw self-priming pump

screw self-priming pump is a positive displacement pump that can transmit various liquid media. It relies on the rotation of the screw to generate negative pressure and achieves self-priming by adsorbing liquid. purpose. Its basic working principle is as follows:

1. due to the rotation of the screw, resulting in negative pressure at the suction end, the liquid began to be pumped into the pump.

2. When the liquid enters the pump, it will move forward with the screw rotation until it is pushed out of the pump outlet.

3. The material is compressed step by step multiple times in the pump, which greatly increases the flow rate and conveying pressure.

4. Screw self-priming pump is characterized by a very small shear force on the liquid during transportation and will not cause damage to the liquid.

5. When the screw runs to a certain speed and the pressure inside the pump reaches a certain value, the liquid in the pump starts to be discharged from the outlet.
The advantages of
2. screw self-priming pumps

1. Excellent self-priming function: The screw self-priming pump can complete self-priming without an additional self-priming device, and has a good self-priming function.

2. Wide range of application: Screw self-priming pump is suitable for the transportation of various viscous liquids and has strong adaptability.

3. Versatility: screw self-priming pump can transport a variety of liquid media, especially suitable for conveying high viscosity media.

4. Low maintenance cost: The screw self-priming pump has a simple structure and is easy to repair and clean.

5. Smooth operation: During the operation of the screw self-priming pump, the liquid flows smoothly without problems such as pulsation and water hammer.

3. screw self-priming pump industrial application

in modern industry viscous liquid conveying is a very important work, screw self-priming pump has the characteristics of conveying viscous liquid, so it has been widely used in the industrial field. For example:

1, petrochemical:

in the petroleum, chemical and other industries, commonly used screw self-priming pump to transport a variety of media to a variety of equipment, such as oil pipes, storage tanks, reactors and so on.

2. Food industry:

In the beverage industry, fruit juice industry and other food industry fields, screw self-priming pumps are often used to transport various high-viscosity food liquids.

3. Sewage treatment:

sewage treatment industry, screw self-priming pumps are often used to transport sewage containing higher concentrations of sludge to accelerate the desired concentration of sewage.

To sum up, the screw self-priming pump is a practical and commonly used industrial equipment, with a wide range of applicability and a series of advantages, and can be widely used in petrochemical, food, sewage treatment and other industries. If necessary, you can choose to use screw self-priming pump to improve engineering efficiency and production efficiency.
