The pneumatic unidirectional diaphragm working principle

8/29/2012 7:52:50 PM
Pneumatic one-way diaphragm composed of two parts of the working chamber and pneumatic chamber separated by the diaphragm, as shown: compressed air into the pneumatic chamber by the air intake, due to increasing pressure on the diaphragm to the left, the main spring compressed and the check valve to open, medium pressure in the working chamber, the pneumatic spool left to close the intake port, the air through the flap valve, pneumatic sleeve, the pressure chamber, by a vented, the pneumatic chamber under reduced pressure, the diaphragm reset and push it to the right, the intake mouth open, into the next action cycle. Continuous reciprocating motion guide the media suction and discharge to complete the work of the transmission medium.
The pneumatic unidirectional Diaphragm pumps are widely used in the packaging and printing industry aqueous ink printing, gravure printing machines, flexographic printing ink surface to enhance the circulatory system, can also be used for conveying various other viscosity liquid, such as water, oils, slurry, corrosion or with small solid particles in a liquid.
Wilden pump compressed air to power, will not produce sparks, electrostatic and electromagnetic interference in the course of their work, and can be directly used for flammable and explosive places.
Reasonable structure, easy to operate. Medium flow according to its viscosity and use demand by changing the pressure of the gas source or the intake air amount of the needle valve to the stepless adjustment. The handle of the pump with back to Mexico, after working at the same time press the two handles, pumps and pipes save more than medium will automatically return to the container, saving raw materials, ease of cleaning work (again need to pull the handle).
