What Should I Do If The Pressure Washer Has No Pressure?
Various equipment used in the field of industrial production often produces grease, scale, coking, high-temperature polymers, deposits, corrosion products, etc., which significantly affect the operating efficiency and safety of the equipment, and cleaning them is inevitable. Compared with the previous manual cleaning, chemical cleaning, ultrasonic cleaning, and even sandblasting, shot blasting, and other processes, the high-pressure cleaner has several advantages such as high efficiency, wide range, good effect, and environmental protection.
High-pressure cleaners need to be maintained and maintained no matter how long they have been used, otherwise, some problems will occur after a long period of use. Generally speaking, in some severe use environments, after a period of use, the water pressure is often very low or no pressure. So, what's the matter with the washer without pressure? What should I do?
1. The cleaning machine cleans the water inlet filter and there is air. After cleaning the air in the water inlet filter, ensure that the output pressure of the standard water is output.
2. The high-pressure pipe and the filter device are kinked, bent, or damaged, resulting in poor water flow, resulting in insufficient water pressure, and should be repaired in time.
3. Leakage of the high and low-pressure water seal and the water inlet and outlet check valves of the cleaning machine causes the working pressure to become low, and these accessories should be replaced in time.
4. The high-pressure nozzle of the cleaning machine is severely worn. Excessive wear of the high-pressure nozzle will affect the water outlet pressure of the equipment. Replace the new nozzle in time.
5. The internal failure of the high-pressure pump, the wearing of vulnerable parts, and the decrease of water flow; the internal pipeline of the equipment is blocked, and the water flow is too small, resulting in too low working pressure.
6. Insufficient inlet water flow of the high-pressure cleaner connected to the equipment leads to insufficient water flow and insufficient output pressure. Sufficient inlet water flow should be supplied in time to solve the problem of reduced outlet pressure.
There are two reasons why the pressure washer has no pressure: one is internal and the other is external.
There may be many internal causes, such as damage to the water seal, damage to the one-way valve, or being blocked by foreign objects that cannot switch normally, the pressure regulating valve cannot regulate the pressure normally, the plunger is worn, and the plunger chamber, swashplate, and spring are damaged. Cause insufficient pressure. Solution: carefully check the parts of the high-pressure cleaner, and replace the damaged parts.
The external causes are mostly unclean water supply, insufficient water supply, and clogged water supply filters. This is a very common fault, and ordinary users will not notice, thinking that the cleaning equipment is malfunctioning, and there is no inspection of the equipment. Reason for detection. 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 the water first, and the water supply is sufficient. If the filter is clogged, clean the water supply filter. If the filter is damaged, replace it with a new one to prevent foreign matter from entering the high pressure. The cleaning machine caused equipment failure and blocked the muzzle.
