The pump for petrochemical industry is a rolling equipment with large consumption in petrochemical production equipment. It transports various liquid mediums such as crude oil, refined oil, chemical raw materials, intermediate products and finished products to other places just like the human heart transports blood.
　　 IMO agent Through years of development, our petrochemical pumps have a complete range of types. Especially since the reform and opening up, many foreign advanced technologies have been introduced, and the technical functions and product quality have made great progress. However, in general, there are still many gaps between internal pump products and external ones: the standardization, serialization and generalization of pumps are poor. Since each manufacturer has its own series, the standardization and interchangeability of parts are low, and there is a lack of unified standards, the standard models of products cannot meet the needs of the petrochemical industry. Second, the quality and reliability are poor. This is mainly due to the lack of types of internal corrosion resistant materials or improper selection of materials, as well as the low processing accuracy; In addition, the seal life of the pump is low and the type is few. The service life of the external mechanical seal can generally reach about two years, but the internal petrochemical pump does not reach this level. Third, the pump power is low. IMO screw pump Because the internal pump planning model is poor, the machining accuracy is not high, and the pump power is generally 2%~3% lower than the external, many chemical process pumps have to be imported from abroad.

In the next five years, the development direction of Sinopec pumps will be large-scale, high-speed, electromechanical, complete set, standardization, serialization and generalization of products. In particular, the production technology of high-temperature pumps, low-temperature pumps and ultra-low temperature pumps, fine metering pumps, corrosion resistant pumps, pumps for transporting viscous media and media with solid particles, and canned pumps will be developed rapidly, and the demand will increase significantly. Dozens of sets of ten million ton refining equipment and one million ton ethylene equipment will be newly built, reconstructed and expanded, creating a broad market for the demand of petrochemical pumps. In addition, all types of pumps in operation in refineries are now aging and in urgent need of renewal and transformation.
Therefore, stainless steel pump valves will have a large development space in my future, which will not be affected by my current number of pump valves. In addition, stainless steel pump valves will gradually replace some pump valves made of other materials, serving industry, agriculture and social life.
In the future, with the continuous development of petrochemical industry technology and planning, the requirements for petrochemical pumps will become higher and higher. In addition to continuing to improve the quality of conventional pumps and expand the standard categories, especially the demand for pumps to transport corrosive materials, such as ethylene cracking equipment, polyethylene equipment and polypropylene equipment in ethylene production, ALLWEILER PTA equipment (purified terephthalic acid), polyester equipment and polyester spinning equipment in the production of chemical fiber, so try to develop corrosion resistant technology.
Stainless steel pump has excellent characteristics of corrosion resistance, high strength, simplicity and long service life. In recent years, stainless steel pumps have been widely used in shipbuilding, rail vehicles and other transportation industries. With the development of machinery manufacturing, stainless steel pumps will have a broader application prospect. However, the growth rate of consumption has gradually slowed down, from the super high-speed development stage where the average annual growth rate of consumption is more than 30% to the steady development stage where the current growth rate is 6.43%.
