The filter press is widely used in various industrial departments. The pump plays an important role in the stability, reliability and continuous work of the whole system. Now, the basic requirements and application scope of the special pump for the lower pressure filter press are introduced.
What are the basic requirements of the special pump for the filter press and the scope of its application?
Special pump for filter press
Basic requirements of special pump for filter press
1, feed: pump flow to foot, can quickly fill the filter chamber filter press.
2, press pressure: the pressure of the pump should be high, and the water content of the filter cake can be reduced as much as possible.
3, the pump's seal is reliable and durable, and can continue to provide stable high pressure.
4. Pump overflow components are resistant to corrosion and wear resistance, and the cost of operation and maintenance is low.
At the same time to meet the above four requirements of the pump, not much. So the pressure filter has not been well solved.
For example, the solvent type (plunger pump, diaphragm pump, screw pump and hose pump) can provide higher pressure, but the general flow rate is not big enough to fill the filter press room quickly, and the cost is generally high, so it can't be accepted by the market.
For example, the centrifugal pump can meet the supply of material: large flow and high pressure, but the above two conditions are two extreme conditions of centrifugal pump operation. If no special design is made, it will be difficult to meet the requirements of the pump for the filter press.
Two, application range of special pump for filter press
1, non-ferrous metal wet smelting production process pump.
2. In the production process of non-metallic mineral products.
3, chemical, dyestuff, pharmaceutical industry and other industries.
4. Transportation of desulphurizer in desulfurization and dust removal engineering.
5, high pressure liquid delivery pump for all kinds of filter press.
6, environmental protection industry to deal with a variety of sewage pressure filter special pump.
7, the oil industry of the oil dewaxing, the machine used to use the pump.
8, the special pump for the filter press used in the food industry (such as starch, corn flour, beer yeast, monosodium glutamate).
