Guide shell assembly

The pump diversion shell is an important part of the pump, also known as the pump shell or pump body. It is a shell fixed at the bottom of the pump to support and protect the internal mechanism.

The main functions of the pump diversion shell are two aspects: one is to guide the fluid from the inlet port into the pump, then flow through the impeller inside the pump, and finally discharge from the outlet port; the other is to protect the rotating parts inside the pump, such as impellers and bearings, etc., to reduce mechanical failure and wear.

The pump diversion shell is usually made of cast iron, stainless steel or other corrosion-resistant materials to ensure its durability and long life. Its internal structure design is closely related to the working principle of the pump to ensure that the fluid can pass through the pump efficiently and generate the required pressure and flow.

In the pump diversion shell, the location and size of the inlet and outlet ports are designed according to engineering requirements and fluid characteristics. The inlet port usually has a larger diameter to reduce the inlet velocity of the fluid and reduce energy loss and eddy current generation. The size of the outlet port is usually smaller to increase the outlet velocity of the fluid, thereby increasing the output power of the pump.

In addition, the pump guide shell may also have other auxiliary facilities, such as positioning devices that guide the impeller to rotate, exhaust devices, access doors, etc., to facilitate the installation, maintenance and maintenance of the pump.

In general, the pump diversion shell plays an important role in the pump system, it not only plays the role of guiding the fluid and protecting the internal mechanism, but also improves the efficiency and performance of the pump.
