Is the more expensive the better when selecting filter press parts?

China filter press manufacturers

In the production process, a production equipment is often very expensive, so in the selection of filter press parts, know how to select will be more cost effective, the filter press is a whole system, to ensure the normal operation of the system, it is necessary to work with many accessories. The filter press system includes feeding, squeezing, cleaning, filter press body, control instrumentation, etc., and of course, the pipeline valve. The body of the filter press is made up of a frame, a liquid accumulation tray, a filter plate, a filter cloth, a cleaning trolley, a plate pulling mechanism, a hydraulic station and a large number of sensors. Henan filter press parts manufacturer would like to introduce you the working information of several main filter press parts.

   First of all, as the core component of the plate and frame filter press, the filter cloth should be disassembled and then cleaned in strict accordance with the disassembly steps in the manual after use, do not ignore this step because of anxiety. In addition, the filter cloth in the usual storage should be placed in a dry environment, because the filter cloth is mostly fiber material, improper visit prone to deterioration, especially the impact of humid climate is more serious.

Material selection of filter plate

   1. PP is currently. Commonly used, that is, polymer polypropylene. This material, for a variety of acid and alkali tolerance is very good, including . Strong acid hydrofluoric acid, all have good resistance. However, the working temperature range is relatively small. It can only withstand materials of 70° for a short time.


   2. PVDF, is acid resistance, temperature resistance. Good organic material, the normal temperature resistance can reach about 150 °, but, alkali resistance is very poor.

   3. Natural rubber filter plate, especially the diaphragm, with natural rubber is still good, good elasticity, but poor strength.

   4. Aluminum filter plate, in all metal filter plate, . Light, but relatively speaking, the acid resistance is poor.

   5. Cast iron filter plate, heavy weight, poor acid resistance, very high temperature resistance. Only the sealing surface, in fact, must also use organic materials to do, so that there are limitations.

   6. Stainless steel filter plate, acid and alkali resistance is better, but the price in all filter plate. Big, after all, the material itself is expensive, and machining is very time consuming.
