stainless steel centrifugal pump, as the name suggests, its material is mainly stainless steel, which is mainly to meet the needs of various chemical substances. 316L stainless steel water pump is mainly made of 316L stainless steel. Stainless steel centrifugal pump is a kind of centrifugal impurity pump, which can transport acidic, alkaline or other corrosive sewage. It is widely used in chemical, petroleum, light industry, pharmaceutical, brewing, environmental protection and sewage treatment industries.
Leak-free has always been the pursuit of chemical equipment. It is this requirement that has contributed to the increasing application of stainless steel centrifugal pumps. However, there is still a long way to go to achieve no leakage, such as the life of the stainless steel centrifugal pump spacer, the corrosion of the material, the performance of the static seal, etc. First of all, regarding the material, the mainstream stainless steel centrifugal pump is generally 304 Stainless steel, 316 stainless steel and 316 stainless steel, the anti-corrosion performance increases in order, the main difference between them is the amount of nickel. You need to consider the use environment when you choose, and choose according to the corrosiveness of the medium. Now some basic information about sealing is briefly introduced as follows
1. For static seals, there are usually only two types of seals and seals, and the ○-shaped seals are widely used; for dynamic seal stainless steel centrifugal pumps, packing seals are rarely used, mainly mechanical seals. Mechanical seals are divided into single end face and double end face, balanced type and unbalanced type. Balanced type is suitable for sealing of high pressure medium, usually refers to pressure greater than 1.0MPa). Double end face mechanical seal is mainly used for high temperature, easy crystallization, viscosity, For media containing particles and volatiles, the double-end machine seal should inject isolating liquid into the sealed cavity, and its pressure is generally higher than the medium pressure by 0.07~0.MPa
2. Sealing material Stainless steel centrifugal pump static sealing material-generally uses fluorine rubber, and PTFE material is used under certain circumstances; the material configuration of mechanical seal dynamic and static ring is more critical, not cemented carbide is better than cemented carbide, the price High is one aspect. There is no difference in hardness between the two and it is unreasonable, so it should be treated differently according to the characteristics of the medium.
In addition, when choosing stainless steel centrifugal pumps, you should consider your specific use environment more. If you are worried about quality problems, choose regular manufacturers and well-known products, so that the after-sales will be more secure. The factors in use should take into account the flow rate and supporting pipelines, and at the same time, calculate the loss of the pipeline and the head of the pump, and determine the pump model based on the calculated data.
Another point is the way of installation. If you only use it in a fixed location, then choose a fixed centrifugal pump; if you need to change the location of use frequently, the mobile type is definitely more suitable.
