Micro-vacuum pump means one with one suction nozzle and one exhaust nozzle, and can continuously form a vacuum or negative pressure at the inlet; a slight positive pressure is formed at the exhaust nozzle; the working medium is mainly gas and the volume is small A kind of instrument Pumps that produce negative pressure should be called vacuum pumps in the technology industry. Because of its small size, light weight, so called miniature vacuum pump. Subatmospheric gas state plus a vacuum, as long as the vacuum can be produced, is the vacuum pump. Nothing less than the difference between the level of vacuum produced Bale. Negative pressure pump, suction pump, suction pump, etc. are commonly known. Someone said that I just aspirated pump, can suck gas on it, do not vacuum pump. In fact, he needs is a vacuum pump, but he is not used for a closed container vacuum only. If the name is not clear, it is not conducive to find the product you need. Specific selection, but also depends on the request. If you need a single suction, you can choose VAA series, PK series, PC series. If you need pumping cheer dual-use, you have to choose FM series, FAA series, PCF series. If you need to adjust the degree of vacuum, flow, you have to choose intelligent vacuum pump ANB series. There are also some issues related to the selection listed below, based on usage considerations. Miniature vacuum pump should pay attention to the problem of attention 1, with the load start problem. If the miniature air pump already had a vacuum on its suction port before the start-up, or the pressure in the exhaust port already exists, consider another pump's technical specifications: the maximum start-up load Pis value for the intake port and the maximum start-up load Pos value for the exhaust port. A typical application example is the use of micro-air pump to maintain the container under vacuum or positive pressure, when the vacuum or positive pressure within the container is lower than the set value, the need for pump power start, higher than the set value shutdown. The products that can be activated under the ultimate vacuum degree that they can reach are: VM series, VAA series, PK series, PC series, VCA series, VCC series, VCH series, PH series; can start under the maximum output pressure that can reach by itself The products are: FM series, FAA series, PCF series. The performance of the manufacturer's technical requirements. 2, micro-pump medium temperature problems. Depending on the temperature of the medium gas passing through the pump, the choice is either ordinary or high temperature. 3, the reliability of micro-pump. Depending on the severity of the consequences of the mini pump failure, it is entirely based on your own requirements. The average quality of trouble-free continuous operation of more than 1,000 hours, some up to thousands of hours. Special attention to this parameter is measured at full load, continuous operation, is the worst operating conditions, if the actual use is not full or continuous operation, the value will be higher, depending on the number of high pump conditions set. The performance is a test of the manufacturer's technical strength entirely, from the product appearance can be seen some, such as the use of special motors instead of ordinary low-cost motor, the case of considerable weight and other heavy. According to product prices can also know a little bit. 4, micro-pump electromagnetic interference problems. If you have a precision circuit-controlled micropump that depends on the circuit's immunity to interference, you may want to order a miniature pump with low electromagnetic interference. Micro-vacuum pump Applications Scientific research, gas sampling, instrumentation, chemical analysis, health care, medical and health, biological engineering, automatic control, environmental protection, water treatment and many other fields.
