Fluoroplastic self-priming pumps mainly include fluoroplastic magnetic self-priming pumps and fluoroplastic centrifugal pumps. Next, fluoroplastic pump manufacturers introduce in detail the problems that should be paid attention to in the selection and purchase of fluoroplastic self-priming pumps:

1. Corrosion resistance: corrosion has always been one of the most troublesome injuries to the mechanical equipment of chemical pumps. If you are not careful, it will destroy the facilities, and seriously will lead to safety accidents and even safety accidents. According to the relevant statistical analysis, about 60% of the destruction of chemical machinery and equipment is caused by corrosion, so we should first pay attention to the rationality of material selection when using chemical pumps. There is a general misconception that stainless steel is an "omnipotent material." No matter how material and natural environmental conditions are, it is very dangerous to hold stainless steel. As a matter of fact, many strong acids and bases commonly used in chemical plants have a very large degree of corrosion on materials, which cannot be described in detail here. In short, do not follow casually and blindly when selecting materials, you should consult more relevant materials or refer to perfect experience.

2. Sealing problem: no leakage is the longing of chemical machinery and equipment, and it is precisely this kind of requirement that promotes the application of magnetic pump to expand day by day.But in the real sense, there is still a long way to go to ensure that there is no leakage, such as the service life of the magnetic pump isolation sleeve, the pitting corrosion of the material, and the stability of the secret.

3. Viscosity problem: the viscosity of the substance has a great influence on the performance of the pump. When the viscosity increases, the lift curve of the pump decreases, the head and flow rate of the better working conditions decrease, while the power increases, so the efficiency decreases. Usually, the parameters on the sample are the performance when transporting clear water, and the conversion should be carried out when transporting viscous substances (the correction factors of different viscosity can be found in the relevant conversion chart). For the transportation of pastes, pastes and viscous liquids with high viscosity, it is recommended to use mortar pump. UHB-ZK 's corrosion-resistant mortar pump is suitable for corrosive substances with viscosity or particles.
