Pneumatic diaphragm pump is easy to use, reliable, open and stop simply open and close the gas valve. Even if there is no medium operation for a long time due to unexpected circumstances or sudden stop of the pump will not be damaged. Once overload, the pump will automatically stop the ground, with self-protection performance, when the load is restored to normal, and can automatically start running.
Pneumatic diaphragm pump simple structure, less wearing parts, the pump structure is simple, convenient installation and maintenance, pump transmission medium will not contact the valve, rod and other moving parts, unlike other types of pump due to the rotor, piston, gear, blade and other parts of wear and tear and the performance of the gradual decline, can transport more viscous liquid. Pneumatic diaphragm pump without oil lubrication, even idling. There is no impact on the pump, this is the main characteristics of the pump, product operation, safe and reliable, corrosion resistance, durable, with self-priming, idling non-destructive, a variety of materials, a wide range of uses, simple device, free from maintenance.
Pneumatic diaphragm pump comprises a pump body, the center of the pump body is installed with a center body, the center body is provided with a center hole and valve installation hole, the center hole is equipped with a central shaft, the installation hole is equipped with a valve. The center body is respectively installed on both sides of the diaphragm, the two ends of the central shaft are fixed on the corresponding diaphragm, the diaphragm and the central body formed between the air cavity, the diaphragm and the pump body formed between the liquid cavity, the bottom of the pump body is provided with two liquid cavity connected water tee, the pump body is provided with two liquid cavity connected water tee, The air valve comprises a spool shaft, a center spool, a spool sleeve, an end spool and other components.
Because the pneumatic diaphragm pump uses air for power, so the flow with the change of back pressure (outlet resistance) and automatic adjustment, suitable for medium and high viscosity fluids. And the working point of the centrifugal pump is set on the basis of water. If it is used for the fluid with slightly higher viscosity, it needs to support the reducer or frequency conversion governor. The cost is greatly increased, and the same is true for the gear pump. Pneumatic diaphragm pump in inflammable and explosive environment with pneumatic pump reliable and low cost, such as fuel, gunpowder, explosive delivery, because:, after grounding can not produce sparks; Second, no heat generation in the work, the machine will not overheat; Third, the fluid will not overheat because the diaphragm pump on the fluid agitation is small.
