Diaphragm pumps can not only pump flowing liquids, but also transport some difficult-to-flow media, viscous liquids, or liquids containing impurities. advantage. It has a unique self-priming ability, so it is also very widely used.
Mainly used in food, chemical, sewage, environmental protection and papermaking industries, the specific needs can be selected according to working conditions and other experience. For example, diaphragm pumps have taken a dominant position in the painting and ceramic industries, while in other jobs, such as environmental protection, wastewater treatment, construction, sewage, and fine chemicals, its market share is expanding, and it has an irreplaceable position for other pumps. . Here are some examples to illustrate:
①Suitable for medium and high viscosity fluids or liquids. Because the working point of the pump is set on the basis of water, if it is used for fluids with slightly higher viscosity, it needs to be equipped with a reducer or a variable frequency governor, which will greatly increase the cost, and the same is true for gear pumps. So it is better to use a diaphragm pump at this time.
②It is more reliable, safe and low-cost to use pneumatic diaphragm pumps in flammable and explosive environments, such as liquid transportation of combustibles.
Because: 1. It is impossible for the diaphragm pump to spark after grounding; 2. No heat is generated during operation, and the machine will not overheat; 3. The fluid will not overheat, because the diaphragm pump has minimal agitation to the fluid.
③ Under the harsh environment and working conditions of the construction site, such as the discharge of wastewater from construction sites and industrial and mining, because the impurities in the sewage are many and the components are relatively disordered, the pipeline is easy to block, which will cause an excessive load on the electric water pump, and the motor will heat up. Fragile. The air-operated diaphragm pump can pass through larger particles and the flow rate is adjustable. When the pipeline is blocked, it will automatically stop until it is unblocked.
④The diaphragm pump is small and easy to move, does not need foundation, occupies a very small area, and the device is simple and economical. Can be used as a mobile material delivery pump.
⑤ Ensure that there is no impurity contamination of materials in hazardous and corrosive materials or in some tests. During processing, the diaphragm pump can completely isolate the material and the conveying medium from the outside world.

⑥It is used to transport fluids or liquids with unstable chemical properties, such as: photosensitive materials, flocculation liquid, etc. This is because the delivery of the diaphragm pump is relatively stable and has little physical impact on the material.
