The air chamber of a diaphragm pump is typically designed to separate the water chamber from the air chamber. When compressed air is introduced into the air chamber, the pulsations in the water within the water chamber are absorbed by the compressed air through the rubber diaphragm. The function of the air chamber is to utilize the compressibility (or elasticity) of air to absorb the pulsations in the diaphragm pump's outlet water, thus stabilizing it. The water flow entering the system is generally stable. However, to achieve this relatively stable flow, the air pressure within the air chamber must be compatible with the water pressure.
Diaphragm pump air chamber inflation method: Before operating the diaphragm pump, inflate the air chamber to a pressure greater than the pump's operating pressure. Drive the diaphragm pump and adjust it to the operating pressure. At this point, you will see the pump's outlet hose vibrating violently. Take a needle-like object and press it against the air nozzle to release the air. As you release the air, the vibration in the outlet hose will gradually disappear. Once the outlet hose stabilizes, stop releasing the air.
