Is It Better To Choose Wear-resistant Or Corrosion-resistant Raw Materials For Vertical Submersible

What are the raw materials for vertical liquid slurry pumps? How to choose wear-resistant or corrosion-resistant?According to common sayings in the industry, the raw materials of vertical liquid slurry pumps are metal raw materials and rubber raw materials. Metal and rubber raw materials can be divided into many types. Different vertical liquid slurry pump raw materials should be selected according to different working conditions. The common metal raw materials are A05 and the rubber raw materials are R55.Metals: A05, A07, A33, A49, Cr30, 304 stainless steel, 316 stainless steel, duplex stainless steel Rubber: R55, ethylene propylene rubber, Hypalen, Resin: polyurethane, polyetherester The above categories are various raw materials commonly used in vertical liquid slurry pumps, among which A05, A49, and R55 are widely used.The characteristics of the vertical liquid slurry pump determine the selection of raw materials for the vertical liquid slurry pump. The vertical liquid slurry pump is a centrifugal pump that transports slurry containing solid particles. It should be a simple liquid that is not a simple liquid, so it is generally required to have good wear resistance.Therefore, the raw material properties of the above slurry pump should be wear-resistant.However, in many special working conditions, we have to abandon certain wear resistance and sacrifice wear resistance characteristics.Selection of corrosion-resistant media for slurry pumps　　In many cases, the slurry we transport not only contains solid particles but also has corrosive characteristics　　The selection of raw materials for vertical liquid slurry pumps must be based on the characteristics of the transport slurry. The expensive ones do not necessarily have to be good, but the suitable ones are good　　For example, when we use stainless steel raw materials to transport slurry with strong abrasive slurry, which is very wasteful and has poor effect;　　It is also undesirable for us to use A05 raw materials to transport slurry with strong corrosive slurry.For example, nitrates, sulfuric acids, and strong alkaline slurries have very fierce corrosion properties, generally between PH0-3 and PH12-14. Because raw materials with good wear resistance do not necessarily have good corrosion resistance, it is necessary to abandon raw materials such as A05 and R55 at this time, and then select A49, Cr30, 304 stainless steel, 316 stainless steel, duplex stainless steel, EPDM rubber, and Hypalen. The prices of these raw materials are generally 1-3 times higher than ordinary raw materials, or even more.How to choose raw materials for slurry pumps 1. Slurry with less acid and alkalinity and no sharp angle particles: A05, A07, common metal mines and coal washing, the first use of vertical liquid slurry pump types: ZJ type vertical liquid slurry pump, AH type vertical liquid slurry pump, ZGB type vertical liquid slurry pump; 2. Slurry with less acid and alkalinity and no sharp angles: R55 rubber raw material, common metal mines and coal washing, the first use of vertical liquid slurry pump types: AH typeVertical under-liquid slurry pump; 3. Slurry with large acid and alkalinity and strong particles with strong corrosion: A49, Cr30, a common desulfurization occupation in power plants; 4. Slurry with strong acid and alkalinity and low temperature and certain abrasiveness: select ethylene propylene rubber and Hapalen rubber raw materials, commonly transported nitrates; 5. Slurry with strong acid and alkalinity and low temperature but not high temperature: select stainless steel raw materials; Select vertical under-liquid slurry pump raw materials based on the principle of cost-effectiveness and suitable!
