Most of the ejection lever-type sprayer for a large area for spraying pesticides, a piston diaphragm pump, this pump is a reciprocating positive displacement pump, the pressure out of the water has a pulsation phenomenon. The general diaphragm pump power from the tractor, driven diaphragm pump speed is generally 500 ~ 600r/min, for example, two-cylinder pump water ripple of the 1000 to 1200 time / min.
Water pulsating sprayer and spray quality are harmful, such pumps have an important part to eliminate pulsation phenomenon; gas chamber. The role of the gas chamber is the use of the compressibility of air (or called elastic), the effluent pulsation of the diaphragm pump is absorbed, so that stabilized.

The structure of the gas chamber is generally separated from the water chamber and the air chamber with a rubber diaphragm. Filled with compressed air to the air chamber, the ripple of the water in the water chamber through the rubber diaphragm gas chamber of compressed air to absorb the water entering the system within the basic smooth. But to achieve a steady flow requirements, there is a premise that the gas chamber pressure should be compatible with the water pressure. Shows that properly inflated air chamber shall diaphragm pump sprayer.

How can inflatable appropriate? Method 1, diaphragm pump operation to apply to the gas chamber inflated, the pressure is greater than the working pressure of the pump. Driven diaphragm pump, adjusted to the working pressure, pump water hose severe jitter can be seen at this time. Take a needle, top deflated at the gas nozzle, water hose jitter phenomenon will gradually disappear with the conduct of the deflated. The smooth water hose to stop deflation. Method 2, driven diaphragm pump to adjust the working pressure. No air pressure due to the gas chamber, pump water hose severe jitter.

Immediately to the gas chamber inflatable with inflatable water hose jitter phenomenon gradually disappears. Smooth water hose to stop inflation. The two methods are in the running state operation, the operation must pay attention to safety.
