As a relatively special customer service sprinkler car models, often appear when the customer service is some small problems, such as sanitation green sprinkler in use after a period of time not pumping water, the drive shaft in turn, but is not pumping water up. This failure needs to be checked and excluded from the following aspects:
First, the pipeline valve position
When pumping, first pumping pipe is connected to the flange, and then the four position three way valve concave position plate to the tank pipe direction (concave point direction of pipeline is closed, which is connected between the port and the suction pipe of the pump body), and then open the handle through valve (parallel to the pipe to open a 90 degree angle, and pipeline off), this is the pumping valve position of the right, the wrong one pipe can not form a natural pathway, is not on the water. This is a novice operating sprinkler often encountered problems.
Two, filter clogging
Most of the time the sanitation green sprinkler pumping on the water, the sales staff will advise our client to clean the filter net. Filter three is located in the middle of three four through the valve and sprinkle water pump, and the other port is connected to the pipe, one into one, the other port with a removable plane, four screws connected. Remove the screws, remove the panel, you can remove the middle of the filter. Clean the filter screen and press it back.
Because the sprinkler, whether it is pumping from the outside of the water, or the release of water from the tank, it must be filtered through this filter. Therefore, the three pass filter of the filter is the need for regular cleaning of the filter, especially in the field of vehicles often carried water, but should increase the frequency of cleaning.
Three, the pipeline seal is not strict
Some users were sprayed in the use of green sanitation sprinkler, sometimes forget to open the car after the operation at the beginning of the spray head, found no water to gas pipeline caused by high-pressure water inside the door, not only ejected from junction with pipeline relatively weak (rubber gasket) release, leading to the rubber pad is extruded under high pressure, thus the formation of pipe seal.
In this case, there will be water seepage in the pipeline connection. The user can remove the pipe rubber pad and re assemble it again, and the rubber gasket with serious deformation should be replaced. When the pipe joint screw, should follow the principle of diagonal twist, not one by one in order to operate, do not screw the screw die, so that the correct installation of rubber gasket.
On the other hand is to check the sealing of the pumping pipe to see if there is damage to the pumping pipe or crack, or the junction of the junction of the Yin and Yang is not stuck in place, etc., which will cause the water pump can not be pumped up.
Four, sprinkler water filter into the water is too deep or too shallow
Then see the sprinkler water filter is too deep into the water, water absorption height is greater than the allowable height, we should confirm that the water filter is less than 5 meters high water absorption, and enough depth. The suction head of the water suction pipe must be completely placed in the water, so as to avoid the air and the water inlet pipe, the vacuum degree is bad, the water pressure is too low to suck up the water.
Five, water shortage
Sprinkler is equipped with a centrifugal pump, the pump every time before water, must be added to a certain amount of water to the pump, plus the need to close the water inlet. Self suction pump is used for the first time, need to add water, then don't need to add water. In the winter when the pump body to avoid cracking, should be more than the water tank and emptying the sprinkler pump, again when working for filling water pump. The sprinkler pump installed in the truck, adding water can be pumping pipe with one end connected to the flange on the water movement in a port, the port will complete the water, let the water into the pump, water filling is completed.
Six, sprinkler vacuum
Sprinkler pump shell cracks, or impeller, leaf damage, or seal damage, will affect the degree of vacuum, water pumping, water pressure is too small or the phenomenon. The user can repair or replace the spare parts according to the trouble shooting method of the sprinkling pump.
