News - What Are The Parts In Centrifugal Pump? The Structure Of a Centrifugal Pump?

Centrifugal Pump Components

A standard centrifugal pump requires the following components to function properly:

1. Impeller
2. Pump Casing
3. Pump Shaft
4. Bearings
5. Mechanical Seal, Packing

Impeller

The impeller is the main part of a centrifugal pump, and the blades attached to the impeller play a major role. Before assembly, the impeller has to undergo static balance experiments. The internal and external surfaces of the impeller need to be smooth to reduce friction losses caused by water flow.

Pump Casing

The pump casing is the main body of the water pump. It plays a supporting and stabilizing role, and is connected to the bracket for installing bearings.

Pump Shaft

The function of the pump shaft is to connect the coupling with the electric motor, transmit the torque of the electric motor to the impeller, so it is the main component for transmitting mechanical energy.

Bearing

Sliding bearings use transparent oil as a lubricant and are filled to the oil level line. Too much oil will leak along the pump shaft, and too little will cause the bearing to overheat and burn out, causing accidents! During the operation of the water pump, the maximum temperature of the bearing is 85 degrees, and it usually operates at about 60 degrees.

Mechanical Seal, Packing

Mechanical seals or packing are important components of the pump designed to prevent fluid contained within the casing from leaking out along the rotating shaft. Mechanical seals or packing are located within the casing at the back portion of the casing. Various types of sealing arrangements may be used based on process variables. Important criteria to consider before choosing mechanical seals or packing are: The nature of the process fluid to be pumped, the pump’s operating temperature and pressure.
