The installation and operation of Axial flow pump

1. Check the pump shaft and the drive shaft is due to the transport process due to bending, if need straightening.

2. Pump installation elevation must be in accordance with the provisions of the installation diagram, to meet the requirements of the cavitation margin and start.

3. The pool water should be provided before settling, avoid the debris with a water pump. Water through the trash rack flow, not to exceed 0.3 M / s for.

4. Water pump installation before the installation angle of the blade to be checked, whether it meets the requirements, whether there is loose.

5. After installation, should check the coupling and the nut of the foot bolt is screwed. Tighten the nut on the shaft and the pump shaft when the screw should pay attention to.

6. The transmission shaft and the pump shaft must be installed on the same vertical line, the tolerance of less than 0.03 mm / m.

7. Water pump outlet pipe should not be installed gate valve. If there is, it must be fully activated before starting.

8. The use of reverse check valve is best to install a balance hammer, in order to balance the weight of the door cover, reduce water resistance, so that the pump more economical operation.

9. Bearings with grease lubrication transmission device, maintenance should oil cavity unpick and wash clean, re injection of grease, the amount to fill the oil cavity of 1 / 2 ~ 2 / 3 is appropriate to avoid the operation of the bearing temperature rise too high. Must pay special attention to the rubber bearing must not touch the oil.

10. Before the start of the pump, should be to the inside of the tube at the upper filler culvert cited injection water or soap water lubricated rubber or plastic bearing, to be the normal operation of pumps, you are ready to stop.

11. The pump should be the first to start before the disk coupling three or four turn, pay attention to whether there is a light and heavy unequal phenomenon. If so, must check the reason, try to eliminate after the operation.

12. Before the start should check the direction of rotation of the click, so that after the pump to turn, and then connected with the pump.

13. Pump operation, should always pay attention to the following points:

(1) Whether the immersion depth of the impeller is sufficient, that is, the water level is too low, so as not to affect the flow, or produce noise.

(2) Impeller outer circle and the impeller housing whether there is friction, the blade is debris around there, rubber or plastic bearing is too tight or burn out, so as not to shaft power increased.
