Folding pump introduction
The sampling pump is mainly used for sample collection of gas or liquid, and thus can be divided into a gas sampling pump and a liquid sampling pump according to the working medium. Due to sampling
The pump is sampled and its volume is very small. Usually we call it a micro vacuum pump.
The basic principle of the sampling pump: the circular motion of the motor, the diaphragm inside the pump is reciprocated by mechanical means, so that the volume in the pump chamber of the fixed volume is compressed and stretched to form a vacuum (negative pressure), at the pumping port At a pressure difference from the outside atmospheric pressure, the gas or liquid is pressed (sucked) into the pump chamber by the pressure difference, and then discharged from the exhaust port.
We refer to small-volume pumps that generate negative pressure as micro-vacuum pumps, but they must be strictly distinguished when selecting products. The true micro vacuum pump is a pump that can vacuum a closed container for a long time, which can drive a large load. The [sampling pump] has a small differential pressure inside and outside the pump chamber during operation, so the load it carries is small. It is because of the different requirements for the loading capacity that the micro vacuum pump and the sampling pump are selected to have great differences. Micro vacuum pumps have high requirements for diaphragms and motors. For these two main parts, the technical indexes such as fatigue strength, reliability, and life are required to meet the conditions under load, and unlike the sampling pump, it is only required to reach the standard under extremely light load (test proves that the load is slightly sampled). The pump is easily damaged). It can be seen that if the micro vacuum pump is used for sampling, it is bound to obtain high reliability, but the price is too high; if the sampling pump is used in a slightly larger load, the reliability and the service life are greatly reduced, and even the normal operation cannot be performed. Although it has an advantage in price. It is best to consult with the technical department when selecting the model to balance cost and performance. Some [sampling pumps] can also achieve better vacuum and flow indicators, but achieving this technical indicator and being able to work reliably for a long time under this indicator are two different things. For example, if a micropump can reach a vacuum of 30KPa, then if the pump's suction port is often under this vacuum, can the pump work reliably? Therefore, the indicator reached by the pump is different from the indicator that it can work reliably.
