Now is the critical period of spring and broadcast, crops began to turn green, severe drought in some places, fountain pumps play a huge role, the following describes the fountain pump installation and troubleshooting some knowledge:
1. Fountain pump installation points
Fountain pump installation location should meet the requirements to allow suction on the vacuum height, the foundation must be level, solid, to ensure that the direction of power machinery and fountain water pump rotation in the same direction. Fountain pump and power machine shaft connection, to ensure that the axis in the same line, to prevent the unit running vibration and bearing single-sided wear; if using tape drive, the axis should be parallel to each other, tape wheel alignment. If there is more than one unit in the same room, there should be more than 800mm distance between the unit and the unit and between the unit and the wall. Fountain pump suction pipe must be sealed well, and minimize the elbow and gate valve, filling the water should be drained of air, run-time tube should not accumulate air, the suction pipe is slightly inclined with fountain pump inlet connection, water intake should be There is a certain depth of submergence. Fountain pump based on the reserved hole, should be based on the size of the fountain pump.
2. Fountain pump common fault analysis and treatment
Different types of fountain pumps, the failure of the form of expression is not the same, but to sum up, have the following five common features.
(1) insufficient flow.
Fountain pump speed is too low; seal ring or impeller wear is too large; high water absorption and so on. In addition, the fountain pump is too low;
The bottom of the valve into the water depth must be greater than 1.5 times the diameter of the inlet pipe to increase the depth of the end of the valve into the water; check the power supply voltage, the water level, Increase fountain pump speed, replace the seal ring or impeller; reduce fountain pump installation location, or replace the high-lift fountain pump.
(2) power consumption is too large.
Cause: fountain pump speed is too high; fountain pump spindle or fountain pump spindle and motor spindle is not concentric or not parallel; use fountain pump head inappropriate; fountain pump inhalation of sediment or blockage; motor ball bearing damage.
Rectify the fountain pump shaft or adjust the relative position of the fountain pump and motor; choose the appropriate head of the fountain pump; clean up sediment or blockage; replace the motor ball bearings.
(3) the pump body vibration or noise.
Cause: fountain pump installation is not strong or fountain pump installation is too high; motor ball bearing damage; fountain pump spindle bending or with the motor spindle is not concentric, not parallel and so on.
Replace the motor ball bearing; correct the curved fountain pump shaft or adjust the relative position of the fountain pump and the motor. 2, The fountain pump is installed in the fountain pump.
(4) shaft or motor bearing overheating.
Reason: the lack of oil or bearing rupture.
Treatment method: Add lubricating oil or replace the bearing.
(5) fountain pump does not water.
Reason: the pump and suction pipe is not filled with water; moving water level is lower than the fountain pump filter pipe; suction pipe rupture.
Reduce the installation position of the fountain pump so that the filter pipe is under the moving water level, or the moving water level rises through the filter pipe and then pumping; Repair or replace the suction pipe.

Reduce the installation position of the fountain pump so that the filter pipe is under the moving water level, or the moving water level rises through the filter pipe and then pumping; Repair or replace the suction pipe.
