Pump House

Pump casing is one of the main components of the pump, plays the role of loading, supporting and fixing the pump rotor and impeller, and also bears the role of internal fluid pressure and external environmental load of the pump. The material of the pump casing is very important to the impact of the pump pressure, which is directly related to the pump's performance, durability and safety.

The material of pump casing mainly has two kinds of metal and non-metal, of which the metal material includes cast iron, stainless steel, copper alloy, etc., and the non-metal material includes plastic, glass fiber reinforced plastic, etc.. Different pump casing materials have different strength, hardness, corrosion resistance and abrasion resistance, so when choosing pump casing materials need to be selected according to specific working conditions and requirements.

Pump casing material on the pump pressure is mainly reflected in the following aspects:

1. Strength and stiffness: the pump casing is the main part of the pump to withstand the internal fluid pressure, so its strength and stiffness directly affects the pump's pressure resistance. Generally speaking, the metal pump casing has high strength and stiffness, can withstand high pressure, suitable for high-pressure pumps in the working environment; and non-metallic pump casing strength and stiffness is low, suitable for low-pressure or general working conditions of the pump.

2. Corrosion resistance: pumps in the working process will be exposed to a variety of media, some media corrosive, easy to produce corrosion of the pump casing, reducing the life of the pump. Therefore, in the selection of pump casing materials need to take into account the corrosive nature of the medium, choose materials with good corrosion resistance, such as stainless steel or special alloys.

3. Abrasion resistance: pump casing in the long-term work will be subjected to media impact and wear, easy to wear and fatigue fracture. Therefore, in the selection of pump casing materials need to consider the abrasion resistance, choose materials with good abrasion resistance, such as high chrome cast iron or wear-resistant alloy.

In summary, the pump casing material on the pump pressure is very significant. The correct choice of suitable pump casing material can improve the working performance of the pump, extend the service life of the pump, and ensure the safety and reliability of the pump in high-pressure, corrosion and wear and other harsh conditions. Therefore, in the design and selection, you need to fully consider the pump pressure and working condition requirements, choose the right pump casing material to ensure stable operation and long-term use of the pump.
