Mini vacuum pump and gas sampling pump how to differentiate between -

gas sampling analysis is often used in environmental protection, Such as car tail gas detection, laboratory gas composition analysis, etc. ) 。 We should be how to distinguish the micro vacuum pump type?

the micro vacuum pump used in scientific research, medical treatment and environmental protection agencies or industry. According to different purposes, the micro vacuum pump can be divided into micro vacuum pump, gas sampling pump, circulating pump, suction pump, the suction pump type, etc.

usually we call it can produce the small volume of the negative pressure pump, but when we select a product must be strictly distinguish them.

real micro vacuum pump, such as VLK mini vacuum pump series, is a long time for vacuum airtight container and can drive heavy load of pump. Widely used in: suction valves can be equipped on it, in the long-term continuous operation under heavy load or vacuum adsorption, etc. Such as system pressure, continuous 24-hour operation, accelerate the liquid filtration, etc.

for gas sampling pump, such as VLC series miniature air pump, the pump cavity pressure difference inside and outside in the running process is very small, so it carries the load is small. But, it is very suitable for only for gas sampling, intermittent use or pump relatively strict noise and volume of occasions, because of its load capacity is weak. Such as vehicle detection, gas composition analysis, microbiological sampling, etc.

due to the different to the requirement of bearing capacity, mini vacuum pump and spare parts of gas sampling pump selection also have very big difference. Micro vacuum pump on the diaphragm and motor has high requirements. For the two major components, fatigue strength, reliability and service life of the technical indicators, such as required under the condition of the load up to standard, and is different from the gas sampling pump under light load is only required to reach the standard ( Load test results show that larger gas sampling pump damage easily) 。 Therefore, the cost of two mini pump is very different.

to sum up, if by micro vacuum pump for gas sampling, is bound to get higher reliability and longer service life, but the cost is relatively high. If the gas sampling pump is used to load a larger occasions, its reliability and service life will be greatly reduced, and even can't work normally, even though it has great advantage on cost. Choice models, it is best combined with the actual situation or consulting professionals, both cost and performance.

a few gas sampling water pump can achieve good vacuum degree and flow index. However, realize the goal of this technology and the ability to work under the goal of long-term reliable are two different things. For example, vacuum micro vacuum pump can achieve 30000 mpa, so when the pump is pumping mouth are often in the vacuum, pump can work reliably? Therefore, the pump can achieve the reliable index is different from it can work.
