There are numerous products in the market of water ring vacuum pump, the manufacturer also has various products, the product quality is uneven, the main reason is that the material of the water ring pump is different. As we all know, the quality of a product is directly affected by its overall quality. What are the specific materials for the water ring pump? We think it’s important for you to understand.
1. Grey cast iron:
Grey cast iron is the first stage graphitization process full of cast iron, all or most of the carbon in flake graphite morphology, fracture in grey color, hence the name, it includes the general grey cast iron, cast iron, grey cast iron, etc. Grey cast iron has a certain strength, but it is very low in plasticity and toughness, which is related to the properties of graphite itself and its existence in cast iron.
It can absorb the energy of the vibration of the machine effectively when it has a good shock absorber, and the base or frame of the machine equipment is made of gray iron. Good lubrication, thermal conductivity and casting properties. Its flow performance is good, the line shrinkage and shrinkage rate are small, and the casting is not easy to crack, so it is suitable for casting and thin-wall casting with complex casting structure.
2. Nodular cast iron:
Nodular cast iron is spheroidized and inoculated with spheroidal graphite, which effectively improves the mechanical properties of cast iron, especially the plasticity and toughness, resulting in higher strength than carbon steel. Its comprehensive performance is close to steel, which is based on its excellent performance, and has been successfully used in casting some parts with high stress, strength, toughness and abrasion resistance.
3. Impeller stainless steel:
Impeller stainless steel, 304 stainless steel, 316 stainless steel, 316L stainless steel.
4. Flow component stainless steel:
(2BV series water ring pump) pump body, disc, impeller have 304 stainless steel, 316 stainless steel, 316L stainless steel.
5. Overall stainless steel:
(2BV series water ring pump) pump body, disc, impeller, pump cover, pump shaft 304 stainless steel, 316 stainless steel, 316L stainless steel; (2BE series, 2SK series, SK series, SZ series) pump body, disc, impeller, pump cover, pump shaft, connecting pipe, upper water vapor separator (2BE series water ring pump), etc.
We know there are many types of water ring vacuum pump type, so the material it is made of different, different models of products made of different material.
