The advantages of diaphragm filter press in filtration
- 2021-09-06-

Diaphragm filter presses have been widely used in petroleum, chemical, food, electronics, ceramics, textile and other industries. They are installed in various special places to extract various media that cannot be pumped by conventional pumps. Satisfactory results have been obtained. However, The application potential of pneumatic diaphragm filter press is not known to many people. Diaphragm filter press uses compressed air as the power source. It is suitable for various corrosive liquids, liquids with particles, high viscosity, volatile, Highly toxic liquids can be exhausted.

Different diaphragm filter press housings and different material diaphragms are selected according to different liquid media. Diaphragm filter press housings are: aluminum alloy, PP plastic, ductile iron, stainless steel, etc. Long, etc. to meet the needs of different users. It has been installed in various special places and used to pump media that cannot be pumped by conventional pumps, and all have achieved satisfactory results.

Due to the remarkable characteristics of the pneumatic diaphragm filter press, it has been gradually invading the market of other pumps and occupying a part of it. For example, the diaphragm filter press has occupied a certain dominant position in the fine chemical industry such as paint and coating and the ceramic industry. position, and in some other industries, such as environmental protection, wastewater treatment, construction, sewage and other industries, it is expanding its market share, and has an irreplaceable position for other pumps.

1. Because air is used as power, the flow is automatically adjusted with the change of back pressure (outlet resistance), and the viscosity range of the applicable medium is wide. The working point of the centrifugal pump is set based on water. If it is used for viscosity Slightly higher fluids need to be matched with a reducer or variable frequency governor, and the cost will be greatly improved, and the same is true for gear pumps.

2. The diaphragm filter press can be used to transport fluids with relatively unstable chemical properties, such as: photosensitive materials, flocculation liquid, etc. This is because the shear force of the pneumatic pump is low and the physical impact on the material is small.

3. In the harsh center of the construction site, such as construction sites, industrial and mining wastewater discharge, due to the large amount of impurities and complex components in the sewage, the pipeline is easy to block, which will cause an excessive load on the electric pump, and the motor will be easily damaged by heat. Diaphragm The filter press can pass through the particles and the flow rate is adjustable, and it will stop automatically when the pipeline is blocked until it is unobstructed.

4. In addition, the pneumatic diaphragm filter press is small and easy to move, does not require foundation, takes up very little space, and is cumbersome and economical to install. It can be used as a mobile material conveying pump.
