Briefly describe the function of the pump cover in a single-stage cantilever centrifugal pump (OH1) Answer: 1. Connected to the pump body, and together with it forms the pressure housing ； 2. Forms an shaft seal chamber together with the shaft (or shaft sleeve), used for installing and fixing the shaft seal ； 3. Connect with the bearing suspension (in some cases, the pump cover is held in place between the bearing suspension and the pump body), thereby fixing the bearing suspension ； 4. Forms the water cooling chamber of the pump cover, cools the shaft seal, and prevents heat from being transferred toward the bearings ； 5. Install the fixed pump cover ring, which is used in conjunction with the rear ring of the impeller (it also creates a small gap with the impeller blades) to balance the axial forces. 6. Implement the P01 flushing scheme
Connected to the pump body, for installing fixed shaft seals, bearings, etc
Answer: 1. Connected to the pump body, and together with it forms the pressure housing； 2. Forms an shaft seal chamber together with the shaft (or shaft sleeve), used for installing and fixing the shaft seal ； 3. Connect with the bearing suspension (in some cases, the pump cover is held in place between the bearing suspension and the pump body), thereby fixing the bearing suspension ； 4.

Install the fixed pump cover ring, which is used in conjunction with the rear ring of the impeller (it also creates a small gap with the impeller blades) to balance the axial forces. 6. Implement the P01 flushing scheme
1. Connected to the pump body, it serves as a pressure housing to form a liquid passage； 2. Install the pump cover ring to work in conjunction with the impeller ring, thereby reducing internal leakage ； 3. Connect to the bearing housing to fix it ； 4. Form an axis seal chamber with the shaft, and install the axis seal

Install the fixed pump cover ring, which is used in conjunction with the rear ring of the impeller (it also creates a small gap with the impeller blades) to balance the axial forces. 6. Implement the P01 flushing scheme
The fluid in the suction pipeline is evenly directed toward the impeller with minimal loss
