1. Development of pneumatic diaphragm pump technology
Domestic diaphragm pump products were originally optimized and upgraded by introducing foreign high-tech products. The earliest diaphragm pump products were designed with external gas distribution valves. The series of diaphragm pump products have a large pump body and a diaphragm diameter. It is also relatively large, the flow and pressure of the entire diaphragm pump are relatively stable during the process, and the efficiency is relatively high. The only defect is the use of an external valve, which is easy to get stuck due to dust in the valve due to environmental factors. The phenomenon.
Subsequently, in order to seize market share, individual diaphragm pump manufacturers in the industry reduced the overall size of the diaphragm pump body and diaphragm, and adopted the built-in gas distribution valve design feature and called QBY3 third-generation pneumatic diaphragm pump. This series The advantage of the third-generation pneumatic diaphragm pump is to change the stuck phenomenon caused by the external air valve that is easily polluted by environmental dust, and because the price of the material is reduced, it will save part of the cost and market than the old pneumatic diaphragm pump. Price positioning is also relatively low.
Due to the low price, the market share is obviously prominent, and in the following two years, various diaphragm pump manufacturers have also successively entered the series of QBY3 pneumatic diaphragm pump products.
But the only shortcoming is that the performance is reduced after the entire volume is reduced. For example, the third-generation pneumatic diaphragm pump, which is also a 25-caliber pneumatic diaphragm pump, is obviously not as old as the pneumatic diaphragm pump. The suction power is greater and the flow rate is obviously smaller. However, on the basis of the QBY3-25 pneumatic diaphragm pump, there will be an upgraded and enlarged QBY3-25A pneumatic diaphragm pump product in order to meet the performance parameters of the original old pneumatic diaphragm pump.
