Material and application range of one-way pneumatic diaphragm pump diaphragm

Asphalt As the saying goes: thousands of miles of the embankment, destroyed by ants. Even if the positioning of a product is too high, but often because of one of the defects but the value of the product greatly reduced, or even worthless. One-way pneumatic diaphragm pump in the actual operation has been quite extensive, and to play an important role, then as a user how we should choose? This article will be from d unidirectional pneumatic diaphragm membrane selection analysis. 1, the plastic diaphragm: imported thick plastic film, fatigue resistance, abrasion resistance, temperature suitable for: 80 degrees Celsius below the material, acid-resistant slightly alkaline; color blue, mainly for the third generation QBY pneumatic diaphragm pump configuration A hole, the diaphragm outer ring thicker, making the pump more solid sealing, and diaphragm more durable than the second generation of pneumatic diaphragm pump (diaphragm diaphragm with the second round of 8 holes easily pull bad). 2, Teflon diaphragm: Imported material corrosion-resistant diaphragm, compared with the PTFE diaphragm in the acid and alkali above have better advantages, relatively higher softness, fatigue resistance, the color is milky white, the best Suitable temperature is less than 80 degrees Celsius. 3, PTFE diaphragm is the most common kind of acid and alkali diaphragm, affordable, the color is white, suitable for some high temperature corrosive liquids. 4, Neoprene: Neoprene is widely used in non-corrosive applications. Features long life and low cost; temperature limits: -17.7 ° C to + 93.3 ° C, 0 ° Fto + 200 ° F. 5, dingqingxiaojiao: dingqing Rubber is mainly used in petrochemical and oil-containing liquid, good elastic life. Temperature limits: -12.2 ° C to + 82.2 ° C, + 10 ° Fto + 180 ° F. 6, ternary rubber: excellent effect for extremely low temperature. Can also be used as acid and alkaline fluids to reduce costs as a substitute. Temperature Limits: -51.1 ° C to + 137.8 ° C, -60 ° Fto + 280 ° F. 7, Fluorinated rubber: Fluorinated rubber used in very high temperature conditions, the effect is very good. Can be used for some acid and alkali products. But high cost and short life expectancy. Temperature Limits: -40 ° C to + 175.7 ° C, -40 ° Fto + 350 ° F. Pneumatic diaphragm pump is a new type of conveying machinery, the use of compressed air as the power source, for a variety of corrosive liquids, with particles of liquid, high viscosity, volatile, flammable, highly toxic liquid can be smoked exhausted , Has now formed a production, product quality acclaimed. The main features of this pump is not need to fill the water, both to move the liquid flow, but also transport some easy to flow medium, suction lift, head adjustable (0-50 m) air pressure only greater than 1kg / cm2 that can work, absolutely fire and explosion. Pneumatic diaphragm pump is the most widely used chemical, scientific research, pharmaceutical, electronics and other watershed products. Adopted a large number of practices, I believe we more or less have formed some of the pump diaphragm on the choice of experience. The above is a summary of some of the Xiaobian on the one-way pneumatic diaphragm membrane selection tips, hoping to be able to help readers, inadequacies please readers pointed out.
