There are several reasons why the air pump pressure can not be hit:
< br >
1. The built-in shrapnel of the air pump has softened for a long time, and when the pressure of the air reservoir reaches a certain air pressure, the softened shrapnel does not bounce up due to the reverse pressure of the air reservoir. This means that the maximum pressure of this problem can hit 4 to 6 kilograms.
< br >
2, the pump pipe is blocked, if the pipe is blocked, it is very good to check, that is, the pump pipe from the side of the dryer, start the pump, if the pipeline out of the black smoke that is the pump pipeline blocked, the solution is to replace the pump pipeline.
< br >
3, where there is leakage in one of the four circuits, the four circuit protective valve automatically closes, this problem is very easy to identify, is to see whether the pressure gauge has a needle to hit 6 pressures, and the other needle has no pressure at all.
< br >
4, because the four-loop protective valve time is too long, the built-in spring is rusty and stuck.
< br >
5, the pipeline is an exception, while pumping air leakage, because the engine sound you can not hear the leakage, when the engine stops working, the air pressure is no more.
< br >
6, the distribution pump leather bowl is broken. It's leaking. You can't hear it.
< br >
7, the switch of the water tank can not be turned off, and the air pressure is missed from the water tank. The inspection method is to hold the inlet pipe of the water tank to pump, if you can play, that is the switch is broken.
< br >
Two, the air pump can not hit the gas how to do
< br >
There are many reasons why the air pump can not be pumped, which may be that the compression exhaust pipe interface is damaged, and the relevant components need to be replaced in time. It may be that the exhaust steel sheet is damaged and needs to be replaced; It may be caused by aging of the shrapnel inside the air pump, which needs to be replaced in time.
< br >
1, the air pump inflation will be slow, may be too small power caused by the need to replace high-power products.
< br >
2, the air pump can not be inflated, may be the tire pressure is too high, so it can not be inflated.
< br >
3, to measure the tire pressure regularly, so as not to affect the normal use.
< br >
4, all the valves of the air pump need regular maintenance, which can extend the service life.
< br >
5, there are many types of air pump, such as pneumatic booster pump, nitrogen booster pump, vacuum stamping pump, high-pressure bottle pump, can be selected according to the use of demand.
< br >
6, the line of the air pump is very thin, daily storage, do not squeeze the wire, so as not to damage the equipment.

Air pump generally refers to the air pump, the air pump is also called the air pump, air pump, air pump, through the operation of the motor to work the motor operation, pumping, the valve of the connecting device is opened by the atmospheric pressure, the gas into the air cylinder, and when the tire is pumped, the valve is closed by the air pressure in the air cylinder, the gas enters the tire.
The shrapnel inside the air pump is aging, which makes it impossible to use.
No normal power supply;
