High pressure water gun is a multi-purpose cleaning water gun, which has the characteristics of water saving, pressurization, environmental protection and so on. Using a high-pressure water gun to wash the car, wash the ground and wash the wall at home has greatly improved our work efficiency. But when we use the high-pressure water gun for work, what should we do when the high-pressure water gun does not come out of the water due to improper operation or other reasons? Now let’s learn about the reason why the high-pressure water gun doesn’t water out and the solution.
What’s wrong with the high-pressure water gun without water
- 1. The inlet filter is partially blocked, resulting in insufficient water supply.
- 2. Before the machine works, the air in the pipeline and high-pressure pump is not discharged first according to the operating procedures.
- 3. The water flow index of the high-pressure water gun exceeds 1000 l / h. generally, the flow of the faucet is about 1000 l / h. If the water flow index of the machine exceeds this value, the pressure may be very small or unstable.
- 4. The pressure regulating valve is not adjusted to the high pressure position.
- 5. The nozzle is a high-low pressure conversion nozzle, but it is in a low-pressure state.
- 6. The nozzle diameter becomes too large due to the long service time of the nozzle.
Water gun does not flow out solution
1. The water inlet filter is partially blocked, resulting in insufficient water supply for the high-pressure water gun. The solution to this problem is to eliminate the blockage of the water inlet filter of the high-pressure water gun, which can be eliminated immediately.
2. Before using the high-pressure water gun, the air in the pipeline and high-pressure pump was not discharged in advance according to the operating regulations. If we encounter such a fault when using the high-pressure water gun, we must first turn off the power supply of the high-pressure washer to keep the water source unblocked. First, press and hold the handle switch of the high-pressure water gun for 1-2min to completely exhaust the air of the high-pressure water gun pipe or high-pressure pump, and then turn on the power switch of the high-pressure water gun to clean it normally.
3. The insufficient inflow flow of the access equipment leads to insufficient water flow, resulting in insufficient output pressure. Sufficient inlet water flow should be supplied in time to solve the problem of water outlet pressure reduction.
4. The pressure regulating valve is adjusted to the high-pressure position, and only the high-pressure state can guarantee the cleaning effect.
5. Generally, the nozzle of the high-pressure water gun is a high-pressure and low-pressure conversion nozzle. If the nozzle of the high-pressure water gun is in a low-pressure state, it will also cause the problem that the high-pressure water gun does not water out. At this time, the nozzle should be adjusted to the high-pressure position.
6. The high-pressure nozzle of the high-pressure washer is seriously worn. Excessive wear of the high-pressure nozzle will affect the water outlet pressure of the equipment, so it should be replaced in time.
7. The high-pressure and low-pressure water seals and water inlet and outlet one-way valves of the high-pressure washer leak, resulting in low working pressure. These accessories should be replaced in time.
8. The high-pressure pipe and filter device are twisted, bent or damaged, resulting in poor water flow and insufficient outlet pressure, which should be repaired in time.
9. After the aging of the overflow valve of the high-pressure washer, the water overflow is large and the pressure becomes low. When it is found that it is aging, it is necessary to replace the accessories in time.
