Pump House

The pump casing is an important part of the pump, its role is to direct the transfer of liquid from the inlet to the rotor part of the pump and through the rotation of the impeller to increase the pressure, and ultimately, the liquid will be discharged out of the pump outlet. Pump casing is usually made of metal material, its design principle needs to consider the following aspects:

1. Fluid transfer: the design of the pump casing needs to consider the fluid flow state in the internal, to ensure that the fluid can pass smoothly through the pump casing, and has the least resistance. The internal surfaces of the pump casing are usually designed to be streamlined to minimize turbulence and eddy currents in the flow of liquid and to improve the efficiency of the pump.

2. Pressure increase: The design of the pump casing increases the pressure of the liquid by converting the kinetic energy of the liquid into pressure energy through the rotation of the impeller. The pump casing needs to have sufficient strength and rigidity to withstand the increased pressure from the liquid and avoid leakage or deformation.

3. Wear and corrosion resistance: Pump casings are often exposed to liquids for long periods of time and therefore need to be wear and corrosion resistant. The pump casing is usually made by surface coating or selecting materials with corrosion resistance to extend its service life.

4. Maintenance and access: pump casing design also needs to consider the ease of maintenance and access, usually through the design of easy to remove and install the structure, in order to replace the impeller or repair the pump casing itself in a timely manner.

5. Heat dissipation performance: the pump casing in operation will generate a certain amount of heat, the need for good heat dissipation performance, in order to avoid high temperatures affecting the normal operation of the pump. The pump casing is usually designed to have a heat sink or ventilation holes to enhance the cooling effect.

In short, the pump casing as an important part of the pump, its design principle needs to consider the fluid transmission, pressure increase, wear and corrosion resistance, maintenance and overhaul as well as heat dissipation performance, etc., in order to ensure the normal operation and performance of the pump. Through the reasonable design of the pump casing, you can improve the efficiency of the pump, extend the service life, and reduce operation and maintenance costs.
