A Brief Discussion On Sanitary Negative Pressure Pump Performance Comparison

Now we only compare the electric plunger airless sprayer with the electric diaphragm airless sprayer. The Sanitary Negative Pressure Pump uses a DC motor to drive the plunger to reciprocate to suck in the paint and discharge it after pressurization. Because its plunger is exposed and the plunger works in the paint, the plunger wears very quickly under the grinding effect of the paint. Once equipped with a nozzle with a larger diameter, the reciprocating frequency of the plunger increases, which increases the wear of the plunger and shortens the life of the machine. The price of replacing the plunger is very expensive. If the voltage is abnormal, it will directly cause the abnormal working DC. In addition, due to the large reciprocating motion, the working pulsation of the sanitary negative pressure pump is very large, making the spraying unstable and the flatness of the wall where the paint is sprayed is not good enough. But the advantage of the sanitary negative pressure pump is that it sucks the material quickly at the beginning. The design of the diaphragm type airless sprayer (sanitary negative pressure pump) is a greater improvement on the basis of the sanitary negative pressure pump. The principle is to use an electric motor to drive the piston to reciprocate (note that the piston does not directly contact the paint), and then push the diaphragm to move, absorb the paint and pressurize it, and then spray it to the coating object through the nozzle. Because its piston works in anti-wear oil, the working environment is greatly optimized, and the life is greatly improved. The piston is not easy to be damaged after being hardened by penetration. In addition, the high anti-twist diaphragm made of polymer material further improves the life of the sanitary negative pressure pump. Reliable operation is another benefit of the sanitary negative pressure pump. The failure rate is extremely low, the voltage requirement is low, the environmental requirement is low, the maintenance is simple, and the maintenance cost is only about one-fifth of the sanitary negative pressure pump. The sanitary negative pressure pump has a good cost performance ratio, and its excellent performance-price ratio will promote the promotion of sanitary negative pressure pumps. The nozzle is another important factor affecting the quality of coating.
