The main structural components of FMC pumps usually include the following parts:
1. FMC pump casing: The FMC pump casing is the main casing of the FMC pump, usually made of cast iron steel plate or steel castings, used to accommodate and support other components. The FMC pump casing usually has an inlet and an outlet for the inflow and outflow of FMC pump water.
2. Impeller: The impeller is the core component of the FMC pump, used to convert the mechanical energy of the FMC pump into fluid energy. It is usually made of metal materials, has a certain number of blades, and its geometry can be designed according to different types of FMC pumps and applications.
3. Booster Device: Some FMC pumps will also add a booster device between the FMC pump casing and the impeller, such as a guide vane ring, a guide vane, etc., which can change the flow direction and speed of the fluid and increase the outlet pressure of the FMC pump.
4. Sealing Device: The sealing device of the FMC pump is used to prevent the leakage of the working medium of the FMC pump or the entry of external air. Common sealing devices include mechanical seals, packing seals, and dynamic and static seals.
5. Shaft: The shaft is a transmission device that connects the drive device (such as a motor) and the impeller. It is usually made of alloy steel and needs to have sufficient strength and rigidity.
6. Shaft Seal: The shaft seal is used for the part of the FMC pump shaft that passes through the FMC pump body to prevent liquid leakage. Commonly used shaft seals include mechanical seals, packing seals, etc.
7. Inlet and Outlet Valves: Inlet and Outlet Valves are used to control the inlet and outlet of fluids. Common types include gate valves, check valves, etc.
