Environmental protection (such as automobile exhaust testing, laboratory gas composition analysis, etc.) often need to use gas sampling analysis, the micro-vacuum pump, miniature pump, miniature pump, micro gas sampling pump, micro gas circulation pump how to distinguish it ? Scientific research, medical care, environmental protection and other institutions or industries, often to use miniature vacuum pump, micro air pump, miniature suction pump, micro gas sampling pump, micro gas circulation pump. Depending on the application, miniature vacuum pump can be divided into: miniature vacuum pump, gas sampling pump, gas circulation pump, suction pump, suction pump and other types. Usually we can produce a negative pressure of the small volume pumps are called miniature vacuum pump, but the product selection must be strictly distinguished. The true sense of the miniature vacuum pump, such as a miniature vacuum pump VAA series: is a long time for the closed container vacuum pump, it can drive a larger load. Widely used in: suction side may be equipped with valves, need long-term continuous operation with a large load or vacuum object adsorption and other occasions, such as system pressure, continuous 24-hour operation, speed up liquid filtration and so on. The gas sampling pump, such as a miniature pump PM series, working pressure pump inside and outside the smaller pressure, so it with a small load belt, but it is because of the weak load capacity, precisely for: only as a Gas sampling, intermittent use or on the pump noise, the volume of more stringent requirements of the occasion. Such as automobile exhaust testing, gas composition analysis, microbiological sampling and so on. It is because of the different requirements of load capacity, resulting in micro-vacuum pump and gas sampling pump parts are very different. Miniature vacuum pumps have high demands on the diaphragm and the motor. For the two main parts, the fatigue strength, reliability, life expectancy and other technical indicators are required to meet the standard conditions with the load, unlike the gas sampling pump only required under very light load standards (test proved that the load slightly Large gas sampling pump is easy to damage). Therefore, the cost of the two micropumps varies greatly. In summary, if the miniature vacuum pump for gas sampling, is bound to get high reliability, longer life expectancy, but the cost is high; if the gas sampling pump for slightly larger load situations, reliability, life Greatly reduced, and even unable to work, although it has greater advantages in cost. Selection of the best combination of their own actual situation or advice to professionals in order to take into account cost and performance. Some gas sampling pump can achieve better vacuum and flow indicators. However, it is two different things to achieve this technical indicator and to be able to work reliably for a long time under this indicator. For example, a micro-pump, can reach 30KPa vacuum, then when the pump suction often in this vacuum, the pump can work reliably? Therefore, the pump can reach the target and reliable indicators of its work is not the same, please be sure to consult professionals to purchase.
