What are the reasons for insufficient pressure in high pressure cleaning machines?
Publish Time: 2024-09-29
There are many reasons why a high-pressure cleaner has insufficient pressure. Here are some common reasons and a brief analysis:
Nozzle wear:
The nozzle is a key component of a high-pressure cleaner. Long-term use will cause wear, which will affect the water outlet pressure. Severely worn nozzles need to be replaced in time to ensure the cleaning effect.
Insufficient water inlet flow:
Insufficient water inlet flow to the device will directly lead to a decrease in the output pressure of the device. Ensure that there is a sufficient and stable water source, and replace or adjust the water source in time when the water inlet is insufficient.
There is air in the water inlet filter:
The accumulation of air in the filter will affect the smoothness of the water flow, resulting in insufficient water outlet pressure. The air in the filter can be exhausted by repeatedly starting the device to ensure that the device can output the standard water outlet pressure.
Aging of the overflow valve:
The overflow valve is an important component for controlling the water flow. Aging will cause the overflow of the water flow to increase, thereby reducing the pressure of the equipment. In this case, the overflow valve needs to be replaced in time.
Leakage of high and low pressure water seals and inlet and outlet check valves:
Leakage of these components will cause the working pressure to become low. Regular inspection and replacement of problematic accessories can effectively prevent such problems from occurring.
High-pressure pipes and filter devices are kinked, bent or damaged:
The physical state of high-pressure pipes and filter devices will affect the flow of water. Kinks, bends or damage will cause poor water flow, thereby reducing the water outlet pressure. Timely repair of these problems can restore the normal pressure of the equipment.
High-pressure pump failure:
The high-pressure pump is the core component of the high-pressure cleaning machine, and its failure will directly affect the water outlet pressure. Problems such as wear of the vulnerable parts inside the high-pressure pump and pipe blockage may cause the water flow to decrease, thereby reducing the working pressure. Regular inspection and maintenance of the high-pressure pump to ensure its normal operation is the key to preventing such problems.
Power supply failure:
Insufficient power supply voltage will affect the normal operation of the high-pressure pump motor, resulting in a decrease in the output power of the high-pressure pump, resulting in insufficient water outlet pressure. Ensure that the power supply voltage is stable and eliminate power supply failures in time to restore the normal pressure of the equipment.
High-pressure pump lubricant aging:
Long-term use of unreplaced lubricants will affect the working performance of the high-pressure pump. In severe cases, it may even damage core components such as the three-piston valve, resulting in insufficient water outlet pressure. Regularly replacing the high-pressure pump lubricating oil and maintaining its good lubrication state is of great significance for maintaining equipment pressure.
There are many reasons for the lack of pressure in high-pressure cleaning machines, involving nozzles, water inlet flow, filters, overflow valves, high and low pressure water seals and inlet and outlet check valves, high-pressure pipes and filtration devices, high-pressure pumps and other components and aspects. During use, these components should be regularly checked and maintained to ensure their normal working condition, so as to avoid the problem of insufficient water outlet pressure.
