Small vacuum pump is also known as micro vacuum pump, because of its small volume, so it is called small vacuum pump in the industry. It can not only realize the suction of gas, but also achieve the effect of pressurization. With the increasing demand for small vacuum pump in the whole market, the matters needing attention in the selection of small vacuum pump have become the focus of business. So in general, what are the precautions for the selection of small vacuum pump?
1. Medium temperature of small vacuum pump.
According to the temperature of the medium gas through the pump, choose to ordinary type or high temperature type.
2. Electromagnetic interference of small vacuum pump.
If there is a precision circuit controlled micropump, depending on the anti-interference ability of the circuit, it may be necessary to order a micro pump with low electromagnetic interference.
3. Reliability of small vacuum pump.
According to the small vacuum pump failure after the severity of the consequences, completely according to their own requirements. The average fault free continuous operation time of high-quality products is more than 1000 hours, some as high as thousands of hours. In particular, this parameter is measured under full load and uninterrupted operation, which is the worst working condition. If the actual use is not full load or continuous operation, the value will be higher, and the higher value depends on the working condition of the pump.
4. Start with load problem.
If there is a vacuum in the suction port or pressure in the exhaust port of a small vacuum pump before starting, another technical parameter of the pump should be considered: the maximum starting load PIs value at the inlet port and the maximum starting load POS value at the exhaust port. 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 to start, and when it is higher than the set value, it will stop.
If the user of small vacuum pump can make correct judgment in product selection, I believe it will provide great help for later work and production. In recent years, China's economy and science and technology have made great progress, I believe this will certainly provide a solid foundation for the development of small vacuum pumps. For the use of products, whether or not to achieve the original purpose, not only need the good value of products, but also need the wisdom of users.
