The reason why the wagon pump does not inflate
1, the air pump built-in shrapnel for a long time softened, and when the storage tank pressure reached 4 air pressure, due to the anti pressure of the storage tank to soften the shrapnel can not be played. That is to say, this kind of fault is most, the pressure can hit 4-6 kilograms.2, pump tube blocking, just as is the tube blocking good check is to pump the pipe apart from the dryer. Tell the driver started up if the line has a black smoke out of something out of that pump pipeline blockage, solution replacement pump pipeline, such as rigid organic waste oil is not oil outflow considering the pipeline blockage.3, the four loop of the road leak, four circuit protection valve is automatically closed, it is well recognized, is to see if there is a pressure gauge needle can hit 6 pressure, another needle is a no pressure.4, because the four circuit protection valve time is too long, the built-in spring rusty and stuck.5, the pipeline broken, blow when the edge of the leak, because the engine sound, you can not hear the leak, when the engine stops working, the air pressure will be gone.6, the pump leather bowl rotten. I can't hear the leak while I'm playing.7. The switch of the water tank is not closed. The air pressure is missing from the water tank. Inspection party
Generally no problem is that there is too much carbon in it. Just remove it and wash it
The cushion of the air pump is damaged, the belt is slipping and broken, the rubber cushion of the non-return valve can not be opened by adhesion, and the air pressure safety valve is not opened back.
