Working principle and structure of brine extraction pump

Brine extraction pumpis a device specifically used for extracting brine, with a unique working principle and structure that can meet the operational needs in specific environments.

I. Working principle of brine extraction pump

The working principle of the brine extraction pump is mainly based on the principle of a centrifugal pump. When the pump starts, the motor drives the impeller to rotate, generating centrifugal force. Under the action of centrifugal force, the liquid is thrown towards the outer periphery of the impeller, gaining energy, and then flows out of the impeller at a higher speed, entering the diffuser tube of the pump casing, and is transported to the destination through the outlet pipeline. The brine extraction pump is particularly suitable for extracting high salinity and highly corrosive brine, widely used in salt mines, chemical industries, and other fields.

The brine extraction pump operates on a hydraulic working principle, which can be simply described as: the motor drives the pump shaft and impeller to rotate, the rotating impeller generates centrifugal force, drawing brine into the pump body and extracting it to the surface through the outlet of the pump body. Inside the pump body, the brine undergoes centrifugal action from the impeller, increasing its flow rate and pressure, thus achieving the lifting and transportation of brine.

II. Structure of brine extraction pump

The brine extraction pump generally consists of a pump body, pump shaft, impeller, and motor. The pump body is the main component of the brine extraction pump, usually made of metal materials, with sufficient strength and corrosion resistance. Various sealing components are installed inside the pump body to ensure its sealing performance. The pump shaft connects the motor and impeller, serving as the support and transmission component of the pump rotor. The pump shaft is generally made of high-quality stainless steel, providing good corrosion resistance and strength. The impeller is the core component of the brine extraction pump, responsible for generating centrifugal force to draw brine to the surface. The structure of the brine extraction pump mainly consists of the following parts:

1. Pump body: The pump body is the main part of the brine extraction pump, usually made of high-strength, corrosion-resistant materials such as stainless steel.

2. Impeller: The impeller is the core part of the brine extraction pump, responsible for generating centrifugal force to give energy to the liquid.

3. Bearings: Bearings support the rotation of the impeller, usually made of materials with good wear resistance.

4. Sealing device: To prevent liquid leakage and ensure the safety of the working environment, the brine extraction pump uses special sealing devices, such as mechanical seals or packing seals.

5. Inlet and outlet pipelines: The inlet and outlet pipelines are responsible for transporting liquid to the destination or receiving liquid from external sources.

6. Drive device: The drive device usually uses a motor to provide power for the brine extraction pump.

In addition, to meet specific operational needs, the brine extraction pump can also be equipped with other auxiliary devices, such as control systems, cooling systems, etc.

III. Conclusion

The brine extraction pump is a device specifically used for extracting brine, with a working principle based on the centrifugal pump principle, and a compact and unique structure. Driven by a motor, the brine extraction pump can transport brine from a lower position to a higher position, or from one place to another. Its structure includes the pump body, impeller, bearings, sealing devices, inlet and outlet pipelines, and drive devices. To meet different operational needs, the brine extraction pump can also be equipped with other auxiliary devices. Due to its reliability and corrosion resistance, the brine extraction pump is widely used in salt mines, chemical industries, and other fields.
