Characteristics of fluoroplastic chemical centrifugal pump： Due to the special requirements of chemical production for pumps, fluoroplastic chemical centrifugal pumps have the following characteristics compared with other centrifugal pumps:
1. Can adapt to the needs of chemical process
In chemical production, fluoroplastic centrifugal pumps must not only transport liquid materials and provide the necessary pressure required by the process, but also ensure the amount of materials to be transported. In a certain chemical unit operation, the flow and head of the pump must be stable to maintain the pump height Efficient and reliable operation.
2. Corrosion resistance
The media conveyed by fluoroplastic centrifugal pumps, including raw materials and reaction intermediates, are often corrosive media. This requires proper and reasonable selection of pump materials to ensure safe, stable and long-life operation of the pump.
3. High temperature and low temperature resistance
The high-temperature medium conveyed by the fluoroplastic centrifugal pump includes process liquid materials and heat-carrying liquid required and produced during the reaction process. There are also many types of low-temperature media transported by fluoroplastics, such as liquid oxygen, liquid nitrogen, methane, etc. Regardless of conveying high temperature or low temperature fluoroplastic centrifugal pumps, the selection of materials and structures must be appropriate, and they must have sufficient strength. The pump parts designed and manufactured can be affected by heat shock, thermal expansion, low temperature cold deformation, cold brittleness, etc.
4. Wear resistance and erosion resistance
Because the flow of fluoroplastic centrifugal pump contains suspended solid particles, and the impeller and cavity of the pump also work at high pressure and high flow rate, the surface protection layer of the pump parts is destroyed and its life is short. Therefore, the fluoroplastic must be improved. The wear resistance and erosion resistance of centrifugal pumps.
