Working principle and characteristics of high pressure […]
Working principle and characteristics of high pressure cleaner high pressure pump: The piston pump is moved back and forth by a fixed seal. The piston pump reciprocates by the piston, so that the working volume of the pump chamber changes periodically, and the liquid is sucked and discharged. The plunger pump seal is mounted on the plunger and passes through a smooth cylinder wall.
It mainly uses the plunger to reciprocate in the pump cylinder. The piston pump is moved back and forth by a fixed seal. The piston pump reciprocates by the piston, and the high pressure cleaner changes the working volume of the pump chamber to realize the suction and discharge of the liquid. The plunger pump seal is mounted on the plunger and passes through a smooth cylinder wall. It mainly uses a plunger to reciprocate in the pump cylinder to form a volume change between the plunger and the pump wall, repeatedly pumping and discharging the liquid and increasing the pressure of the pump. Piston pumps generally have better initial use characteristics, and have the advantages of high rated pressure, compact structure, high efficiency and convenient flow adjustment, but their disadvantages are that they cannot operate at excessive pressure and have a short service life.
The water capacity of the pump depends on the speed at which the pump is running. The pump must allow the same amount of water to enter and exit. The water flow parameter of the piston pump is stable. The flow rate of the water sprayed at different pressures of the equipment is constant. Therefore, if the nozzle or the high pressure pipe is clogged, the high pressure pump will be under pressure. Therefore, a device such as a pressure relief valve must be installed in the equipment system.
High pressure cleaners are prone to failures. The cause of failure is usually not because of pumps. Pump failures are generally caused by wear of components or components, such as nozzle seal wear. It is one of the main causes of failure in the early stage of the pump. Generally speaking, the inlet pipe diameter is too small or the water supply is insufficient, resulting in insufficient water to enter the pump interior, causing cavitation in the pump. Cavitation causes a small explosion of gas mixed in the water to cause overpressure damage, causing the piston surface to wear.
The above is a brief description of the pump of the high pressure cleaner. The pump is the heart of the operation of the pressure washer, so the quality of the pump affects the cleaning effect and service life of the machine. Click Hub Motor for more details.
