Analysis of working principle of silent oil-free vacuum pump
1、 Where is the oil-free vacuum pump:
At present, there are few domestic manufacturers producing oil-free vacuum pumps. Basically, they can only produce rotary vane vacuum pump products that must be filled with vacuum oil. The market is basically imported oil-free vacuum pump products. The oil-free rotary vane vacuum pump of Boyu company is manufactured by using the oil-free rotary vane vacuum pump technology of the United States and Taiwan. It has the advantages of simple structure, easy operation, convenient maintenance and no environmental pollution. The two series of oil-free vacuum pumps have good durability. They are dual-purpose vacuum pumps for vacuum pumping, compression and are basic equipment for obtaining vacuum in a very wide range of applications.
2、 Working principle of oil-free vacuum pump: oil-free vacuum pump is the same as general positive displacement pump, which is composed of stator, rotor, rotating blade, cylinder block, motor and other main parts. The rotor with rotating blades is eccentrically installed in the stator cylinder. When the rotor rotates at a high speed, the four radial sliding rotating blades in the rotor slot separate the pump cavity into four working chambers. Due to the centrifugal force, the rotating blades cling to the cylinder wall, separating the stator inlet and outlet, and running round and round, changing the volume, and discharging the inhaled gas from the exhaust port, so as to achieve the purpose of air extraction, It replaces the disadvantage that 2XZ rotary vane vacuum pump needs vacuum oil to be used.
Principle: oil free design, reciprocating operation of piston, no need for maintenance, save trouble and worry.
Technology: advanced technology, precise structure, extremely low noise, avoiding noise interference
Quality: through 3000 hours of continuous load test, reliable quality, two-year warranty, no worries
Configuration: there is a vacuum regulating valve, which is convenient for the operator to manually adjust to the required vacuum pressure; Another simple installation kit is available for purchase, so users can easily and quickly convert the vacuum pump into a positive pressure pump.
Oil free vacuum pump is a rotary vane single-stage vacuum pump. It is a basic equipment used to extract gas from sealed containers to obtain vacuum.
The pump can be used for various vacuum operations, such as the repair of air conditioners, refrigeration equipment, suction devices of medical instruments, printing machinery, vacuum packaging, vacuum blistering, physical and chemical experiments, and small devices requiring vacuum environment. It can also be used as the front stage pump of small oil booster pump, oil diffusion pump, molecular pump, etc.
The pump is not suitable for pumping out gases that corrode ferrous metals, chemically react with pump oil, contain particulate dust, and toxic gases that contain too much oxygen and are explosive. It cannot be used as a transfer pump (that is, pumping from one container to another).
