Pneumatic diaphragm pump is a brand new pump products, the pump to compressed air as the power, through the air exchange valve reversing mechanism and other parts to achieve reversing to drive the reciprocating motion of the diaphragm in the pump chamber, resulting in pressure difference in the chamber, so as to achieve the function of suction and discharge media. Pneumatic diaphragm pump to solve the traditional diaphragm pump large structural defects (external valve, easy to crash, and make the valve suitable for short life), built-in valve, really realize never crash, and compact structure, long service life, convenient maintenance, and far beyond the performance of the old diaphragm pump. The mine pump with the coal safety mark is nothing more than the drainage pump of the coal mine with high gas and prominent gas, and its fire prevention and explosion prevention, especially suitable for the use of high gas mine and petroleum, chemical and other departments.
Pneumatic diaphragm pump is a reliable fluid transfer tool, with a number of advanced design of the valve, low requirements for air source, no lubrication, high efficiency and other advantages. Pneumatic diaphragm pump can transport a variety of viscosity fluid, treatment containing solids and can be easily adjusted transport advantages.
The advantages of pneumatic diaphragm pump are:
1. Because of air power. The working characteristics 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.
2. In inflammable and explosive environment with pneumatic pump reliable and low cost, such as fuel, gunpowder, explosives transportation, because:
First, it is impossible to produce sparks after grounding;
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.
3. In bad places, such as construction sites, industrial and mining wastewater discharge, due to the impurities in sewage and complex composition, pipeline is easy to plug, so that the electric pump will form too high load, motor heating daily loss. Pneumatic diaphragm pump can be through the particle and flow adjustable, the pipeline is blocked when the automatic stop to smooth.
4. In addition, the diaphragm pump is small and easy to move, does not need foundation, covers an area of small, easy and economical. Can be used as mobile material transfer pump.
5 In hazardous, corrosive material processing, diaphragm pump can be completely separated from the outside world.
6. Or some experiments to ensure that no impurities contaminate raw materials.
7. It can be used to transport fluid with unstable chemical properties, such as photosensitive materials and flocculant. This is because the diaphragm pump shear force is low.
Since the birth of pneumatic diaphragm pump is gradually invading other pump market, and occupy a part of it. For example: spray painting, ceramics industry diaphragm pump has occupied the dominant position, and in some other industries, such as environmental protection, wastewater treatment, construction, sewage, fine chemical industry is expanding its market share, and has the irreplaceable status of other pumps.
