Overview
QBYK3 is a highly efficient compact pneumatic diaphragm pump newly
developed through adopting most advanced reliable pilot-operated type air
valve. It is upgraded on the basis of traditional manufacturing technology.
Operating efficiency is guaranteed while its shape is optimized to shrink.


Working principle
There installs each diaphragm in both aligned working cavities A & B, which can be connected together with a central coupling lever. The compression air enters the air distribution valve from the air entrance of the pump, draw the compression air into one cavity through the air distribution mechanism, push out the diaphragm movement in the cavity. The gas in another cavity will be drained. Once reaching the stroke terminal, the air distribution mechanism will automatically draw the compression air into another working cavity, push out the diaphragm to move towards the opposite direction, so as to let the both diaphragms continuously reciprocate motion in synchronism.

The compression air enters the air distribution valve from E shown as the diagram, let the diaphragm piece move towards the right direction. And the suction force in A chamber lets the medium flow into from C entrance, push out the ball valve ② to enter A chamber, the ball valve ④ will be locked due to the suction force; The medium in B chamber will be pressed, push out the ball valve ③ to flow out from the exit D. Meanwhile, let the ball valve ① close, prevent backflow. Such movement in circles will let the medium uninterruptedly suck from C entrance and drain from D exit.



Features
1.Adopt the forerunner type air valve, eliminate the phenomenon of downtime, prolong service life.All parts can be in without open the lumen.
2.More than port design, easy to install.
3.Adopts nonporous embedded diaphragm, improve the utilization of diaphragm, and make the structure more light.
4.Small easy to move, do not need the foundation, take up little tiny, installation simple and economic.Can be used as mobile conveying pump.
5.Can be an external electromagnetic valve, facilitate remote control operation.
6.Reversing valve without lubrication.
7.Intermediate is suitable for a variety of specifications of the pump.
