There are two reasons why the high-pressure cleaning machine has no pressure: one is internal and the other is external.
There may be many kinds of internal causes, such as water seal damage, one-way valve damage or being padded by foreign matters, unable to open and close normally, pressure regulating valve unable to regulate normally, plunger wear, and plunger chamber, swashplate and spring damage, which may cause insufficient pressure. Solution: carefully check all parts of the high-pressure cleaning machine and replace the damaged parts.
The external causes are mostly unclean water supply, insufficient water supply and blocked water supply filter, which is a very common fault, which is not noticed by ordinary users. They think that the cleaning equipment has failed, and they go to the equipment for inspection, but they do not detect the cause. Solution: increase the pressure of the water source. If the tap water supply is insufficient, it is recommended to find a water container to store water first, so as to ensure sufficient water inflow. If the filter is blocked, clean the water supply filter. If the filter is damaged, replace it with a new filter to prevent foreign matters from entering the high pressure. The cleaning machine causes equipment failure and muzzle blockage. （GaoYaQingXiJiMeiYouYaLiShiYinWeiShenMe）
