Overview
The directional air distribution valve and the main air valve, known as the "air chamber", are both located at the center of the pump. The medium flows through two manifolds and the outer diaphragm chamber of pump $r $n, forming the 'medium chamber'. Usually, check valves (ball valves) are installed at the top and bottom of each outer diaphragm chamber, usually sharing a common manifold. These two outer diaphragm chambers are connected to the inlet and outlet ports, and the pump is self-priming.
Product Details
During the operation of the pump, the compressed air distribution valve alternately changes the direction of operation of the main air valve, forming air flow pulses in the chamber and automatically changing its position,
Enable the air to switch to another diaphragm chamber, creating alternating suction and compression strokes on both sides of the diaphragm chamber. Diaphragm in parallel path
Moving inside, the air valve does not require lubrication, which requires clean and dry air to improve the performance of the pump.
When the medium passes through the pump, the check valve opens and closes alternately, which causes each outer diaphragm chamber to be filled and ejected alternately. The check valve acts on the pressure difference
React. Ball check valves can handle media containing small particles.
When the air distribution valve allows compressed air to enter the left diaphragm chamber, the diaphragm is compressed and pushed out, forming a compression stroke in the compression section
The medium is forced to leave the left outer diaphragm chamber, check valve, and manifold, and then flows out from the outlet of the pump. The discharge outlet is located at the top of the pump
When the left diaphragm is pushed out under pressure, the diaphragm connecting rod pulls the right diaphragm inward to form a suction stroke, so that the medium is filled
Fill the outer diaphragm chamber on the right side, and the medium flows into the pump at the inlet, filling the chamber through an open inlet check valve. In this cycle
After the action is completed, the air distribution valve will automatically change position, causing the air to switch to another diaphragm chamber and repeat the above cycle in reverse.
The two diaphragm chambers exhibit alternating pressure and suction actions.
