The main components of the pressure washer are the high pressure pump, the high pressure pump is in an irreplaceable position, and the high pressure washer piston pump is the most common because they are more powerful and have a longer life. After a fixed seal, the plunger pump seal is mounted on the plunger and passes through a lubricated cylinder wall. The plunger pump generally has better initial operating characteristics, but cannot operate with excessive pressure and has a longer life. short.
The capacity of the pressure washer pump depends on the speed of the pump and it is necessary to bring the same amount of water in and out. Unlike centrifugal pumps, they can increase or decrease flow. The piston pump has a very stable water flow parameter. No matter how high the pressure is, the pressure at the outlet of the nozzle will become too high. Therefore, equipment such as pressure relief valves are installed in the system.
When the piston moves backwards, water is sucked into the sealed chamber through the inlet valve. When the piston moves forward, water is forced to flow through the outlet valve to the outlet of the pump. Most piston pumps are double or triple. Dual piston pumps require higher and more stringent system components and operators. Triple pumps are the most versatile of pressure washers because of the smoother water flow. High-speed pumps can generate less pressure loss and require less starting torque. However, it can create faster wear, less inhalation, and can be noisy and potentially damaging.
90% of high-pressure cleaners generally do not suffer from pumps. The most common problems are caused by the wear of components or components (such as nozzle seals). The lack of pump inlet water is the primary cause of premature pump failure. The inlet pipe is not It is appropriate that water cannot be brought into the pump to form a cavitation phenomenon. Cavitation causes a small blast in the gas mixed with water to cause overpressure damage and wear on the piston surface.
