Rotary vane vacuum pump of typical application

Rotary vane vacuum pumps are a popular and effective solution for transporting clean, low to medium viscosity fluids and fuels within a certain temperature and relatively low pressure range. Rotary vane vacuum pumps are the best choice for the following applications:

Fuel and light oil transmission
Lubrication method
Gasoline/petroleum
Liquefied petroleum gas (propane)
Chemical treatment
Alcohol and solvent
Bitumen transfer
High temperature fluid
Liquefied petroleum gas

The design of sliding vane pumps makes them generally unsuitable for high viscosity applications because the thick liquid prevents the vanes from easily moving in and out of their slots. In addition, their very tight tolerances mean that solids cannot pass through and can clog the blades. Therefore they are suitable for relatively clean liquids.

Rotary vane vacuum pumps are often used in low-pressure equipment rather than high-pressure equipment. As the pressure in the pump chamber increases, the blades try to maintain contact with the casing wall and push the fluid around.

2XZ rotary vane vacuum pump

The 2xz rotary vane vacuum pump makes the diaphragm inside the pump reciprocate through a mechanical device

The 2xz rotary vane vacuum pump is also a miniature vacuum pump, because of its small size, the miniature vacuum pump is usually called a vacuum pump. A small vacuum pump (namely a miniature vacuum pump) refers to: one suction nozzle and one exhaust nozzle with one inlet and one outlet, and can continuously form a vacuum or negative pressure at the inlet; a slight positive pressure is formed at the exhaust nozzle; the working medium is mainly It is a gas, a compact instrument. Small vacuum pumps can be used for air-conditioning, repair of refrigeration equipment, suction devices for medical instruments, printing machinery, vacuum packaging, vacuum blister, physical and chemical experiments and small devices requiring a vacuum environment for various vacuum operations. The scope of application involves many fields such as scientific research, gas sampling, instrumentation,

2xz rotary vane vacuum pumps are not suitable for pumping out gases that are corrosive to ferrous metals, chemically react to pump oil, and contain particulate dust, as well as 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).

The circular motion of the 2xz rotary vane vacuum pump motor makes the diaphragm inside the pump reciprocate through a mechanical device, thereby compressing and stretching the air in the pump cavity with a fixed volume to form a vacuum (negative pressure), and it is connected to the pump suction port. The outside atmospheric pressure produces a pressure difference. Under the action of the pressure difference, the gas is pressure (suctioned) into the pump cavity, and then discharged from the exhaust port.

2xz rotary vane vacuum pump of attention should be paid to the use:

1. Start with load.
If the vacuum pump has vacuum at its suction port or pressure at its exhaust port before it is started, another technical parameter of the pump must be considered: a large starting load at the intake port and a large starting load value at the exhaust port.

2. The medium temperature of the vacuum pump.
According to the temperature of the medium gas passing through the pump, it is possible to choose the normal type or the high temperature type.

3. The reliability of 2xz rotary vane vacuum pump.
According to the seriousness of the consequences after the failure of the micropump, it is completely according to your own requirements. Pay special attention that this parameter is measured under full load and uninterrupted operation, which is a bad working condition. If the actual use is not full load or continuous operation, the value will be higher, and how much higher depends on the working condition of the pump. . This performance is entirely a test of the manufacturer’s technical strength. Some can be seen from the appearance of the product, such as the use of special motors instead of ordinary low-cost motors, and the weight is heavier in the case of equivalent volume. Normally, high quality equal to high price.

4. The electromagnetic interference problem of 2xz rotary vane vacuum pump.
If there is a precision circuit to control a small vacuum pump, depending on the circuit’s anti-interference ability, it may be necessary to order a small vacuum pump with low electromagnetic interference.
