1. Regionality. At present, most domestic products are facing the dilemma of having accessories without technology and without accessories. Because of the regional problems of raw materials, the prices of liquid ring vacuum pumps are uneven.
2. The material of the pump body can be divided into nodular cast iron and grey cast iron. Nodular graphite is obtained by spheroidizing and inoculation treatment, which effectively improves the mechanical properties of cast iron, especially the plasticity and toughness, thus obtaining higher strength than carbon steel. Ductile iron is a kind of high strength cast iron material developed in the 1950s. Its comprehensive properties are close to steel. It is precisely because of its excellent properties that it has been successfully used to cast some parts with complex stress, high strength, toughness and wear resistance.
3. Technical content of liquid ring vacuum pump. As we all know, the maturity of technology, the stability, reliability and life of products manufactured by high-standard processing and production equipment have an impact.
4. Quality of accessories. The liquid ring vacuum pump is mainly composed of several parts, such as filter, marble, exhaust hood, etc. The quality of these parts directly affects its price.
