What are in the process of using a small vacuum pump considerations -

small vacuum pump is also called the micro vacuum pump, because it is small in size. Small vacuum pump ( The micro vacuum pump) Means: it has a suction nozzle and an exhaust nozzle, and can be continuous vacuum or negative pressure formed at the entrance; The micro positive pressure exhaust nozzle; Working medium is gas, is a small volume of the instrument. Small vacuum pump can be used for air-conditioning, refrigeration equipment, medical equipment maintenance suction device, printing machinery, vacuum packaging, vacuum suction, physical and chemical experiments, and vacuum operating environment and other small devices. Applications involving scientific research, the gas sampling, instruments and meters, chemical analysis, medical care, medicine and health care, biological engineering, automatic control, environmental protection, water treatment and many other fields.

small vacuum pump is not suitable for pumping corrosion of ferrous metals, react with pump oil, containing dust particles, and contains too much gas of oxygen and explosive toxic gas. It cannot be used as a transfer pump ( The pump from one container to another container) 。

a small circular motion by mechanical device of vacuum pump motor do reciprocating movement of the diaphragm pump, compressing and stretching fixed volume of air pump cavity, forming a vacuum ( Negative pressure) In the pump suction and the outside world produce pressure differential between the atmospheric pressure, under the action of pressure difference and gas by pressure ( Suction) Into the pump chamber, then from the outlet.

should be paid attention to the use of small vacuum pump:

1. Load startup problem.

if the small vacuum pump before starting the suction vacuum or in the vent pressure, should consider to another technical parameters of the pump: the entrance to the largest start load and vent the biggest start load.

2。 Temperature problems of small vacuum pump. According to through the temperature of the gas pump medium, choose ordinary type or high temperature.

3。 The reliability of the small vacuum pump. According to the micro pump failure of the seriousness of consequences, completely according to your requirements. Should pay special attention to, this parameter is under full load and uninterrupted operation measure, this is the worst working conditions. If the actual use is not full or run continuously, the value will be higher, depending on the pump working conditions. All this performance test the manufacturer's technical strength, and can be seen from the appearance of the product, such as using a dedicated motor instead of the ordinary low-cost, under the condition of the same volume of weight is heavy, etc. According to the price of the product, you can also know a little about it.

4。 Small vacuum pump electromagnetic interference. If there is a small vacuum pump control precision circuit, according to the circuit anti-interference ability, low electromagnetic interference, small vacuum pump may need orders.
