Today Huaian diaphragm metering pump manufacturers only the power piston airless spraying machine and electric diaphragm airless spraying machine for everyone to make a comparison, plunger type metering pump is a DC motor unit piston movement will re paint inhalation, after the discharge pressure, because of its exposed plunger and the plunger in the paint work in coating grinding effect to guess. Under the plunger wear very quickly, once with a larger diameter nozzle, the plunger reciprocating frequency progress, increasing plunger wear, short life of machine.

The replacement of the plunger is very valuable, and if the voltage is not normal, it will lead to the abnormal direct current of the operation. In addition, because of the large back and forth reciprocating movement, the operation pulsation of the plunger pump is very large, which makes the spraying unstable, and the roughness of the wall surface on the paint is not good enough. But the quicker initial feeding of the plunger pump is the benefit of the pump.

Diaphragm type airless sprayer (diaphragm metering pump), the plan is to get more improvement in piston pump based on the principle for the use of motor piston reciprocating operation of femoral artery (note that the piston is not in direct contact with paint), and then promote the gap movement, will push out the pressure absorbing coating, coating to the object through the nozzle because of its operation in the piston spray, abrasion proof oil, greatly optimize the operation environment, life greatly improved, through the penetration of hardened piston is not easy to damage, polymer material with high anti twist to his estrangement diaphragm further progress.

Reliable operation is another benefit of the barrier pump. The failure rate is very low. For the bottom of the voltage request, the repair of the environment request is simple, and the repair cost is only 1/5 of the piston pump. The estrangement pump is cost-effective and its excellent performance quotation will promote the promotion of the estrangement pump. The nozzle is another important factor affecting the quality of the coating.
