Small vacuum pump selection considerations

The small vacuum pump is also called a miniature vacuum pump. Because it is small in size, the industry calls it a small vacuum pump, which can not only achieve the suction of gas, but also achieve the effect of boosting. With the increasing market demand for small vacuum pumps, the selection of small vacuum pumps has become a must-see for businesses. Under normal circumstances, what are the precautions for selecting a small vacuum pump?

Small vacuum pump selection Note 1, the medium temperature of the small vacuum pump.

Depending on the temperature of the medium gas passing through the pump, whether it is common or high temperature is selected.

2. Electromagnetic interference problems with small vacuum pumps.

If there is a precision circuit control micropump, depending on the ability of the circuit to resist interference, it may be necessary to order a miniature pump with low electromagnetic interference.

3, the reliability of small vacuum pumps.

According to the severity of the consequences of a small vacuum pumping failure, it is entirely based on its own requirements. The average fault-free continuous running time of quality products is greater than 1000 hours, and some are as high as thousands of hours. Special attention is paid to this parameter, which is measured under full-load and uninterrupted operating conditions. It is the worst case. If the actual use is not full or continuous operation, the value will be higher, depending on the working condition of the pump. set.

4, with the load start problem.

If the vacuum pump has a vacuum before the start of the small vacuum pump or there is pressure in the exhaust port, another pump technical parameter must be considered: the maximum starting load Pis value of the air inlet, and the maximum starting load Pos value of the air outlet. A typical application example is to use a micro air pump to maintain the vacuum or positive pressure in the container. When the vacuum or positive pressure in the container is lower than the set value, the pump needs to be powered on. If it is higher than the set value, it will stop.

If users of small vacuum pumps can make correct judgments when selecting products, it is believed that they will be able to provide great help for subsequent work and production. In recent years, China's economy and science and technology have made significant progress, I believe this will certainly provide a solid foundation for the development of small vacuum pumps. For the use of the product, whether it can achieve its original purpose requires not only the good value of the product, but also the wisdom of the user.
