Introduce the use of several common pneumatic diaphragm pump accessories

1. Polyester membrane imported material thickened poly film, fatigue resistance, friction resistance, suitable temperature: materials below 80 degrees Celsius, micro acid and alkali resistant; color blue, mainly for the middle of the third generation of QBY3 pneumatic diaphragm pump configuration Hole, diaphragm outer ring thicker, making the pump body more reliable sealing, and the diaphragm is more durable than the second generation of pneumatic diaphragm pumps (second diaphragm pump diaphragm with 8 holes around the easy to pull out) Diaphragm The size of 127MM/170MM/228MM/277MM

2, Teflon diaphragm imported material corrosion resistant diaphragm, compared to PTFE diaphragm has better advantages in acid and alkali resistance, softness is relatively higher, fatigue resistance, color is milky white, the best suitable The temperature is less than 80 degrees Celsius; the diaphragm size is 127MM/170MM/228MM/277MM

3, PTFE membrane The most common type of acid and alkali resistant diaphragm, economical, the color is milky white, suitable for some high temperature corrosive liquids, diaphragm size points 127MM/170MM/228MM/277MM

4, PTFE / PTFE ball base resistant to acid and alkali, white appearance, is the most commonly used Ball Valve seat diaphragm pump, durable PTFE ball size: 25mm/37mm/44mm PTFE ball seat size: 9mm/12mm/ 32mm/90mm

5、Pulse damper: It can make the material delivered by the pump can flow out smoothly. For some manufacturers who supply glue and other materials, it is recommended to install a pulse damper at the discharge port of each pump, which can adjust the discharge pressure and adjust Flow, etc. 6. Connecting rod shaft The connecting rod shaft is one of the main components of the pneumatic diaphragm pump valve chamber. Stainless steel, through the connecting rod shaft to push the diaphragm reciprocating movement, is generally not easy to damage.

7. The inner diaphragm pneumatic diaphragm pump diaphragm is mainly tightened by two platens. The main material is stainless steel. The size is determined by the size of the diaphragm pump. 8. Pneumatic triple coupling: Pneumatic triple coupling is an adjustment of the diaphragm pump inlet pressure, filtering air and Oil and water separation of three major functions, through the pneumatic three-piece adjustment of pressure can play a role in regulating the diaphragm pump flow; For some air quality is not a good working environment is recommended to install a pneumatic three-piece, to ensure the stability of the pneumatic diaphragm pump and service life; A certain amount of lubricating oil can be added to the pneumatic triple unit to ensure the humidity in the diaphragm pump intermediate.
