The basic structure of horizontal multistage centrifugal pump is composed of six parts, namely: pump body, pump shaft, centrifugal impeller, bearing, sealing ring, stuffing box.

1. The pump body is also called the pump casing, which is the main body of the pump. It has the effect of supporting and fixing, and is interconnected with the bracket of the device bearing.
2.Horizontal multistage centrifugal pump manufacturers tell you that the effect of the pump shaft is to connect the coupling and the motor to each other, and transmit the torque of the motor to the centrifugal impeller, so it is the primary component for transmitting mechanical kinetic energy.
3. The centrifugal impeller is the central part of the self-balancing multi-stage pump. It has a high speed and a large output. The blades on the centrifugal impeller play a primary role. The centrifugal impeller must pass a static balance test before assembly. Horizontal multistage centrifugal pump manufacturers tell you that the inner and outer surfaces of the centrifugal impeller are required to be smooth to reduce the conflict loss of water flow.
4. Bearing is a component that is sleeved on the pump shaft to support the pump shaft, and there are two kinds of rolling bearings and sliding bearings. Horizontal multistage centrifugal pump rolling bearings use tallow as a lubricant. Generally, the volume of 2/3 to 3/4 of the oil should be appropriate. Too much volume will generate heat, and if too little, there will be noise and heat. Sliding bearings use transparent oil as lubricant, add oil to the oil standard line. During the operation of the self-balancing multi-stage pump, the maximum temperature of the bearing is 85 degrees, and the general bearing temperature is about 60 degrees. to deal with.
