How to select micro vacuum pump micro air pump? With the vigorous development of China's instrument and meter industry, the volume of delicate, oil-free and environmentally friendly micro vacuum pump, micro air pump is more and more common use. How can we choose the most suitable product for you in the specification of complicated micro pump?
According to the use of micro pump, can be divided into three categories to comment:
First, it is assumed that compressed air is output only by miniature air pump. To put it simply, it is used only to energize and inflate, and the suction port of the pump is basically unused. The situation is relatively simple
Two, assuming the following situations, the piston pump series of goods should be selected.
1. Micro pumps are used to pump air or vacuum, but sometimes liquid water enters the pump chamber.
2, supplication micro pump can pump air and water.
3, mainly with micro pump pumping, but do not hope to artificially add "water diversion" before pumping (some pumps in the operation before the demand for artificial participation in some "water diversion", so the pump can pump the water at the lower part, otherwise the pump can not pump and damage.) That is, the pump is expected to have a "self-priming" function. The interests of the piston pump series of goods lies in that when there is no contact with water, it will be vacuumized. After forming a vacuum, the pressure will come up by air pressure, and then start pumping.
4, with micro pump pumping, but sometimes the pump may not have water to pump, in the "dry turn" situation. Some traditional pumps fear "dry turn", "dry turn" and even damage the pump. The piston pump series is essentially a compound function pump, it integrates the function of vacuum pump and water pump, someone called it "vacuum pump". So when there is no water, it vacuums, and when there is water it pumps. Whether pumping is still pumping, all belong to the normal operation category, there is no "dry rotation" damage.
Three, the assumption is to use micro pump pumping, the situation is a little messy, roughly from the following two aspects to determine the selection. The micro pump used for air extraction is divided into two categories: gas sampling pump and micro vacuum pump. Although they are often undiscriminately referred to simply as the miniature vacuum pump, but from the technical point of view of the two are different, the selection of more special attention.
