The products of the liquid ring vacuum pump market are numerous, and the vacuum pump manufacturers are also diverse. The quality of the products is uneven. The main reason is that the material of the liquid ring vacuum pump is different. We all know that the quality of a product directly affects its overall quality. What are the specific materials for manufacturing liquid ring vacuum pumps? We feel that it is necessary for everyone to understand.
2BV Series Liquid Ring Vacuum Pump
The following are professional manufacturers of Shanghai EVP vacuum pumps, which summarizes the materials for manufacturing liquid ring vacuum pumps.
1. Gray cast iron
Gray cast iron is the cast iron obtained in the first stage of the graphitization process. All or most of the carbon exists in the form of flake graphite. The fracture is gray and dark, hence the name, it includes general gray cast iron, cast iron, rare earth ash. Cast iron and so on. Gray cast iron has a certain strength, but the plasticity and toughness are very low. This performance characteristic is related to the properties of graphite itself and its existence in cast iron structure.
It has good shock absorption. When using gray cast iron to make parts such as base or frame on machine equipment, it can effectively absorb the energy of machine vibration; it has good lubrication performance, thermal conductivity and casting performance. The flowability is good, the linear shrinkage rate and the body shrinkage rate are small, and the casting is less prone to cracking, so it is suitable for casting castings and thin-walled castings with complicated structures.
2, ductile iron
Ductile iron is obtained by spheroidizing and inoculation to obtain 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 that of steel. It is based on its excellent performance and has been successfully used to cast some parts with high stress, high strength, toughness and wear resistance.
3, impeller stainless steel: impeller stainless steel material is 304 stainless steel, 316 stainless steel, 316L stainless steel.
4, over-current parts stainless steel: (2BV series liquid ring vacuum pump) pump body, disc, impeller has 304 stainless steel, 316 stainless steel, 316L stainless steel.
2BE1 Series Liquid Ring Vacuum Pump
5, the overall stainless steel: (2BV series liquid ring vacuum pump) pump body, disc, impeller, pump cover, pump shaft has 304 stainless steel, 316 stainless steel, 316L stainless steel; (2BE series, 2SK series, SK series) pump body, disc , impeller, pump cover, pump shaft, connecting pipe, upper steam separator (2BE series liquid ring vacuum pump), and so on.
We know that there are many types of liquid ring vacuum pumps, so the material of the liquid ring vacuum pump is not the same. Different types of products are made of different materials, and the corresponding liquid ring vacuum pumps are also different in price.
