Centrifugal pumps-the choice across industries

Centrifugal pumps work by using the impeller to rotate to make the water produce centrifugal movement. It is mainly divided into six parts: impeller, pump body, pump shaft, bearing, sealing ring, and stuffing box.It has the characteristics of good sealing, controllable flow, fully automatic, and high working efficiency.

In the chemical, petroleum, smelting, water conservancy, sewage treatment, and pipeline transportation industries, centrifugal pumps play an important role in dredging and transporting. For lightly corrosive liquids, centrifugal pumps can also withstand the test.

In addition, the centrifugal pump also has the advantages of uniform flow, stable operation, low vibration, and no need for special shock absorption.

The role of centrifugal pump

Centrifugal pump refers to a pump that transports liquids by the centrifugal force generated when the impeller rotates. Centrifugal pumps can be widely used in industries such as electric power, metallurgy, coal, and building materials to transport slurry containing solid particles.

Such as the hydraulic ash removal of thermal power plants,Slurry transportation in metallurgical beneficiation plants,Coal slurry and heavy-medium transportation in coal washing plants. When the centrifugal pump is working, the pump needs to be placed on the ground and the suction pipe is placed in the water.Before starting the centrifugal pump, the pumped liquid must be filled with the suction pipe, impeller and pump casing.

The basic composition of the centrifugal pump: the centrifugal pump is composed of six parts, namely the impeller, the pump body, the pump shaft, the bearing, the sealing ring, and the stuffing box.

1. The impeller is the core part of the centrifugal pump. It has high speed and large output. The blades on the impeller play the main role. The impeller must pass the static balance experiment before assembly. The inner and outer surfaces of the impeller should be smooth to reduce the friction loss of the water flow.

2. The pump body is also called the pump casing, which is the main body of the water pump. It plays a role of supporting and fixing, and is connected with the bracket for mounting the bearing.

3. The function of the pump shaft is to connect the motor with the coupling, and transmit the torque of the motor to the impeller. It is the main component for transferring mechanical energy.

4. The sliding bearing uses transparent oil as a lubricant, and it is generally necessary to add oil to the oil level line.

5. The sealing ring is also called the leakage reducing ring.

6. The stuffing box is composed of packing, water seal ring, packing tube, packing gland and water seal pipe. Its function is to close the gap between the pump casing and the pump shaft, so that the water in the pump does not flow to the outside, and the outside air does not enter the pump.
