High pressure cleaning machine does not have pressure how to do?

Time: July 9, 2020 14:23 source: unknown author: admin

The reasons for insufficient water pressure of high-pressure cleaning machine can be roughly divided into three types: one is motor failure or insufficient power supply; the second is that the high-pressure pump is worn or injected with impure oil; the third is that the high-pressure gun barrel is damaged or the rubber gasket in the gun head is not sealed.

1. If there is air in the water inlet filter of the high-pressure cleaning machine, the air in the clean water inlet filter should be exhausted to ensure the output standard outlet pressure.

2. The high-pressure nozzle of high-pressure cleaning machine is seriously worn. Excessive wear of high-pressure nozzle will affect the water outlet pressure of the equipment, so the new nozzle should be replaced in time.

3. Leakage of high and low pressure water seal and inlet and outlet water one-way valve of high-pressure cleaning machine leads to low working pressure, so these accessories should be replaced in time.

4. The insufficient inlet water flow of the connected equipment leads to insufficient water flow and insufficient output pressure. Sufficient inflow should be supplied in time to solve the problem of decreasing outlet pressure.

5. High pressure pump internal failure, wear of vulnerable parts, water flow reduced; equipment internal pipeline blockage, water flow is too small, resulting in low working pressure.

6. The high-pressure pipe and filter device are kinked, bent or damaged, resulting in poor water flow and insufficient outlet pressure, which should be repaired in time.

When the pressure of the pressure washer is unstable, most of the reasons are caused by the air in the pipeline,

Treatment method: check the pressure of water source and whether the water filter is blocked.

When the high-pressure cleaning machine cannot adjust to the rated pressure of the equipment, the reasons are as follows:

(1) judge whether the aperture of high pressure nozzle matches.

Check whether the pressure regulating valve is set to the position.

After starting the equipment, when there is no water from the high-pressure water pump, most of the reasons are that the inlet flow valve cannot be opened.

When the bottom of the high-pressure water pump drips oil, the reason is that the oil seal inside the pump is damaged, so it should be replaced in time.

When the machine is running, the high pressure pipe vibrates violently. The reason is that the valve works disorderly and needs to be re pressurized.

When the machine is running normally, the water gun does not come out of water or the water jet is irregular and dispersed. The reason is that the high-pressure nozzle is blocked by foreign matters, which should be cleaned up in time.
