The micro vacuum pump, mini pump and the difference between the gas sampling pump 3)

the micro vacuum pump | | the micro pump | tiny negative pressure pump of the micro pump, usually we can produce small volume pump suction is called mini vacuum pump, but we must strictly distinguish between while selecting a product. In the true sense of the micro vacuum pump ( Such as VM series, PK series, PC series can be a long time of airtight container vacuum pump, it can drive the larger load. The gas sampling pump ( Work such as PM series, PS series pump cavity inside and outside differential pressure is small, so it is with the load is small. Because of different to the requirement of load capacity, mini vacuum pump and gas sampling pump chosen parts have very big difference. The micro vacuum pump, mini pump have high demands on the diaphragm and motor. For the two main parts, fatigue strength, reliability, life and other technical indicators are required under load conditions, and different from gas sampling pump requires only under light load standard ( The experiment proved that slightly bigger load gas sampling pump is easy to damage. Therefore, the cost of two kinds of micro pump varies widely. Above all, if the mini vacuum pump, mini pump used for gas sampling, is bound to get a high reliability and longer life, but higher cost; If the gas sampling pump used in load slightly larger occasions, reliability, life is compromised, even cannot work normally, even though it has great advantage on cost. Selection of the best in combination with the practical situation of themselves or advice to us, so that both the cost and performance. Some of the gas sampling pump can achieve good vacuum degree and flow indicators. However, to reach the technical index and able to work under the indicators and reliable for a long time are two different things. For example, a micro pump, can achieve the KPa vacuum, so often when the suction port of the pump in the vacuum, pump can work reliably? Pump can achieve index and, therefore, it can work reliability index is not the same, when buying, please must be confirmed to the manufacturer or distributor.
