Miniature diaphragm vacuum pump selection guide

With the vigorous development of instrumentation industry, compact, oil-free miniature vacuum pump, miniature diaphragm vacuum pump is more and more widely used. How can we choose the most appropriate product in the most diverse miniature pumps? Miniature Diaphragm Vacuum Pump Selection Guide Miniature Diaphragm Vacuum Pump Selection Guide We must first clear the purpose of micro-pump. First, if only the output of compressed air micro-pump. Simply put, it is to use it to cheer, inflatable, pump exhaust port basically do not have. This situation is relatively simple, according to the output pressure in descending order: PCF5015N, FAA8006, FAA6003, FAA4002, FM2002, FM1001. Of course, we also refer to flow indicators and other related technical parameters. Second, if it is the following situations, you should choose PHW600B or WAA series products. 1, with a mini pump or vacuum pump, but sometimes there will be liquid water into the pump chamber. 2, require micro-pump both pumping and pumping. 3, the main pump with a miniature pump, but do not want to manually increase before pumping water diversion. (Some pumps require manual "priming" before work so that the pump can pump low water up or the pump can not pump or even damage.) The beauty of the PHW600B or WAA series is that when it comes in contact with water It is evacuated, the formation of a vacuum by air pressure up, and then began pumping. 4, using micro-pump pumping, but sometimes there may be no pump pump water, in a "dry turn" state. Some traditional pumps fear "dry turn", and even fatal. The PHW600B or WAA series is essentially a compound function pump that integrates the functions of a vacuum pump and a pump, some call it a "vacuum pump." So, in the absence of water, it will be evacuated, and when it has water it will pump it. Whether pumping or pumping state, belong to the normal work category, it does not matter "dry turn" damage. Third, if it is micro-pump pumping, the situation a bit more complicated. 1, determine the micro-pump pumping end conditions for pumping the micro-pump is divided into two categories: gas sampling pump and miniature vacuum pump. Although they are often referred to as miniature vacuum pumps simply and indiscriminately, they differ from the technical point of view and require special attention. In short, the gas sampling pump can only be used with a small load (ie, the pump suction resistance must not be too high), but the price is very low; in the strict sense of the micro-vacuum pump can carry a large load (suction end allow large resistance, or even complete Blocked), but the price is slightly expensive. The specific difference between the two can be found in the article "on the difference between miniature vacuum pump and gas sampling pump." Gas sampling pumps are: PM series (specific models such as: PM950.2, PM850.5, PM8001, PM7002, PM6503); miniature vacuum pumps are: VM series, VAA series, PK series, PC series, VCA series, VCC series, VCH Series, PH series, FM series, FAA series, PCF series, all the specifications under these series are real miniature vacuum pump, such as VM7002, VAA6005, PC3025 and so on.
