High-pressure cleaners are divided into three categories: household, commercial and industrial. Industrial high-pressure cleaners, in addition to general requirements, often have some special requirements. Water cutting is a good example.
The heart of high-pressure cleaners is high-pressure pumps, which are in an irreplaceable position. Piston pumps are the most common. Because they are more efficient and have a longer life, pistons are usually made of ceramics that are very resistant to wear. Piston pumps are often described as one. The root piston moves back and forth. Through a fixed seal; the plunger pump seal is mounted on the plunger. Through a smooth cylinder wall, the plunger pump usually has better initial use characteristics, but cannot operate at excessive pressure and has a short life. .
The pump must allow the same amount of water to enter and exit. It does not increase or decrease the flow rate like a centrifugal pump. The piston pump has a very stable water flow parameter, no matter how high the pressure is injected, the flow rate of the nozzle will cause the high pressure pump to be under pressure. Therefore, devices such as pressure relief valves are installed in the system.
Most piston pumps are double or triple. Dual piston pumps are more demanding and rigorous for system components and operators. Triple pumps are the most versatile form of high pressure cleaners due to their smoother water flow. High-speed pumps can produce less pressure loss and require less starting torque.
