summarize
Electric variable frequency diaphragm pump is a new type of pump, in recent years, due to the breakthrough progress in the diaphragm material, more and more industrialized countries in the world use this type of pump to replace part of the centrifugal pump, screw pump to be used in petrochemical, ceramics, metallurgy and other industries. It can transport particles and mud with a diameter of less than 10 mm. Since the diaphragm will be separated by the conveying medium and the transmission machinery, the medium will not leak outwards, and the pump itself has no shaft seal, and the service life is greatly extended. The diaphragm is made of chlorohydrin rubber, fluoro rubber, butadiene rubber and other materials, which can meet the requirements of conveying different media.
peculiarity
1. Do not need irrigation water.
2. Through the performance is good, diameter of 10 mm below the particles, mud, etc., can effortlessly pass.
3. Because the diaphragm will be separated by the conveying medium and the transmission machinery, the medium will not leak outwards; And the pump itself has no shaft seal, the service life is greatly extended; According to different media, the diaphragm can be divided into neoprene rubber, fluorine rubber, butadiene rubber, polytetrafluorohexene, Teflon (F46), etc., can meet the requirements of different customers.
4. The pump body medium flow part, according to different user requirements, divided into cast iron, stainless steel, rubber lining, aluminum alloy, motor can be divided into ordinary motor, explosion-proof motor, deceleration motor and electromagnetic speed regulation motor.
Diaphragm selection
The main component of the electric frequency conversion diaphragm pump is the diaphragm, the correct selection of diaphragm can achieve the purpose of twice the result with half the work, the user must indicate the nature of the conveying medium when ordering, so that the factory is equipped with different diaphragms, the diaphragm has the following types:
1. Ding Qing diaphragm; Mainly used in oil-resistant occasions.
2. Neoprene rubber: mainly used for resistance to acetone and various acids and bases.
3. Fluorine rubber: mainly used for high temperature 150℃ :, corrosion resistance. But the price is higher than other diaphragms.
4. Food rubber: for food and beverage delivery.
