China water truck for sale
First, the water truck pipe clogging of the filter, because the water truck pump pumped into the water is not all clean tap water may be dirty pool or pond pumping water, so the water too many impurities, the filter is easily Miscellaneous was blocked, such as sand, plastic bags, twigs and other debris through the screen just need to remove the filter to clean the inside tee, ensure the smooth flow can resume normal work, the location of the filter pump in water truck intake pipe end. Second, worn impeller deformation, resulting in a normal rotation sprinkler pump impeller out of the water but can not be normal, you can simply replace the impeller.
Third, the water pump seal a gap, causing air to enter, inadequate sprinkler pump pressure, the solution is to carefully check the working of the pump if there is a gap leakage of water.
Fourth, in the dry water truck pump pumps work, leading to pump mechanical seal appears dry heating phenomenon can replace the mechanical seal.
Fifth, the lack of shaft power, so that the pump impeller does not reach normal operating speed, the throttle can be.

To ensure that the pump has good self-absorption properties, you must meet the following criteria:
1, before the pump working fluid must be higher than the stock pump shaft so pump inlet must be connected to an upwardly curved bend followed by a horizontal tube and quick connector, quick connector must be above the centerline of the shaft centerline 300 mm.
2, the system must ensure that the inlet pipeline does not leak, good sealing performance.
3, suction head suction pipe must be submerged in water, in order to avoid air intake pipes.
4, outlet pipe and pump outlet must ensure that when connecting the straight tube length ≥200 mm and then take the elbow.
5, the intake pipe ends must tees filters, ensure that the water does not enter the impurities damage the pump before the pump precision components
