Installation And Use Of Centrifugal Pump

1. Before installing the centrifugal pump, make the foundation according to the shape and installation size, and install it according to the position of the pipeline to facilitate management.

2. If the position of the centrifugal pump is higher than the liquid level, an additional filling device must be installed.

3. Fill the pump body with liquid before starting the centrifugal pump. It is strictly forbidden to run and reverse without medium, otherwise the mechanical seal will be damaged due to lack of liquid cooling in the pump body.

4. Close the valve of the liquid pipe when it is stopped to avoid backflow of the liquid.

5. To repair the centrifugal pump, first disassemble the pump body, then loosen the mechanical seal screw, and fold down the mechanical seal.

6. If the ball bearing or pump shaft is replaced, the frame must be folded down, the 4 screws of the front bearing cover must be loosened, the rear end garden nut and coupling of the pump shaft must be folded, and the pump shaft can be punched out in the front end direction. Fold down the rear end shaft seal cover

7. When reassembling after overhaul and replacement of wearing parts.

1. Install the front and rear bearings and oil seals in the front and rear covers respectively, and install the front cover with bearings on the pump shaft, and then install the pump shaft with the front bearing cover on the frame.

2. Put the bearing press sleeve on the pump shaft, and then install the rear cover with the bearing on the pump shaft and the frame.

3. Set the pressure ring, install the coupling and tighten the nut.

4. Put the mechanical seal ring on the pump shaft.

5. Install the static ring in the pump body and tighten the compression nut

6. Put the pump body with static ring on the frame, debug the fit of the dynamic and static rings of the mechanical seal (generally 3-3.5 mm tight), and take off the pump body first.

7. Fasten and fix the mechanical seal moving ring on the pump shaft, and then; l Wait for the pump body to be installed on the frame, and turn the mechanical seal dynamic and static rings on the coupling by hand to see if the fit is correct.

8. Install the impeller on the pump shaft, and use a PTFE gasket to adjust the gap between the impeller and the pump body (generally between 2-2.S mm), pad the anti-corrosion gasket, then tighten the impeller and cap, and pad it well at the end Pump casing gasket, install the pump cover, and tighten the anti-corrosion nut.

9. Install the assembled pump head on the bottom plate, and adjust the gap of the coupling to be perpendicular to the axis of the motor.

8. Pay attention to the daily maintenance of the FRP centrifugal pump, often check whether the pump is running smoothly and whether there is abnormal vibration, pay attention to replacing the elastic block, supplement the lubricating oil of the bearing according to the oil mark, and replace the lubricating oil in the frame regularly (generally, it must be changed every three months). l times)
