Talking about the performance of diaphragm pump and plunger pump

The diaphragm type airless spraying machine (diaphragm pump) is designed to be improved on the basis of the plunger pump. The principle is to use the motor to drive the piston to work reciprocally (note that the piston does not directly touch the paint) and then push the diaphragm movement. The paint is absorbed and pressurized, and then sprayed through the nozzle to the painted object. Because the piston works in the anti-wear oil, the working environment is greatly optimized, the service life is greatly improved, and the piston which has been subjected to the penetration hardening treatment is not easily damaged. The high anti-stranding diaphragm made of polymer material further improves the life of the diaphragm pump. Reliable operation is another advantage of the diaphragm pump. The failure rate is extremely low, the voltage requirement is low, the environmental requirements are low, the maintenance is easy, and the maintenance cost is only about one-fifth of the plunger pump.

The diaphragm pump is cost-effective, and its excellent performance-price ratio will promote the promotion of diaphragm pumps.

Kanbel high-pressure airless spraying machine has many original technologies of the world. The PrimeBoosterTM system can be restarted and loaded in seconds, solving the technical problem of the initial suction difficulty of the airless sprayer. The innovative DAPIV inlet valve design greatly reduces the possibility of the valve being stuck by the paint, plus high-power electric With a motor and a sturdy, one-shot housing, the Kemplar sprayer is capable of handling a wide range of short-term, high-task construction tasks. The nozzle is another major factor affecting the quality of the coating. Its quality is evaluated as wear resistance and uniform atomization. The nozzles of American Canber products are made of hard alloy, which is wear-resistant, high in coating quality and relatively cheap. It makes the diaphragm pump even more powerful and becomes the leader in coating machinery. !

The high-pressure airless spraying has high efficiency, the surface is smooth and flat, the adhesion is strong, and the coating loss is small, which is widely used in the construction, machinery, shipbuilding, furniture and other industries.

High-pressure airless sprayers are divided into pneumatic airless sprayers, electric airless sprayers (plunger pumps) and electric airless sprayers (diaphragm pumps), which are limited by the need for a compressed air source for pneumatic airless sprayers. The use of pneumatic sprayers.

Now only the electric plunger airless spraying machine is compared with the electric diaphragm airless spraying machine. The plunger pump drives the plunger to move the plunger to move the paint, and then discharges it after pressing, because the plunger is exposed and the plunger Working in the paint, the plunger wears very quickly under the action of the coating. Once equipped with a nozzle with a large diameter, the plunger reciprocating frequency is increased, the wear of the plunger is aggravated, and the life of the machine is short. The replacement of the plunger is very expensive, and if the voltage is not normal, it will directly cause the working DC to be abnormal. In addition, due to the large reciprocating motion, the plunger pump has a large pulsation, which makes the spraying unstable, and the flatness of the wall sprayed by the coating is not good enough. However, the quick suction of the plunger pump is its strength.
