Petrochemical pump prospects to the pursuit of technological development
The petrochemical industrial pump is the largest amount of rotating equipment used in petrochemical plants. It delivers a variety of liquid media such as crude oil, refined oil, chemical raw materials, intermediate products and finished products to other places as human heart pumps blood. China's petrochemical pump through years of development, more complete varieties, especially since the introduction of reform and opening up a lot of foreign advanced technology, technical performance and product quality has been greatly improved. However, in general, the domestic pump products compared with foreign countries, there are still many gaps: First, the pump standardization, serialization and generalization of the poor. Due to the self-developed series of manufacturers, parts standardization and low interchangeability, the lack of uniform standards, product specifications also can not meet the petrochemical industry development needs. Second, the quality and reliability is poor. This is mainly due to less domestic varieties of corrosion-resistant materials or improper material selection, as well as processing accuracy is not high; the other pump seal life is low, less variety. Foreign mechanical seal life expectancy generally up to two years, the domestic petrochemical pump has not yet reached this level. Third, the pump efficiency is low. As the domestic pump design model is poor, the processing accuracy is not high, the pump efficiency is generally 2% lower than the foreign 3%, so there are many chemical process pump had to be imported from abroad. The next five years Sinopec pump development direction is large, high-speed, mechanical and electrical integration, and product sets, standardization, serialization and generalization. In particular, high temperature pumps, cryogenic pumps and cryogenic pumps, precision metering pumps, corrosion-resistant pumps, viscous media and transport medium with solid particles pump, shield pump production technology will rapidly develop, the demand will increase substantially. Dozens of sets of tens of thousands of tons of refineries and millions of tons of ethylene plant will be the new construction and expansion, the demand for petrochemical pumps has opened up a vast market. In addition, all kinds of pumps operated in various domestic refineries have been aged and need to be updated and reformed urgently. Therefore, stainless steel pump valve in our country there will be great room for development is great, not because of the current amount of valve in our country is affected, and, stainless steel valve will gradually replace some of the previous material pump Valve, for the industrial and agricultural and social services. In the future, with the continuous development of the technology and scale of the petrochemical industry, the requirements for petrochemical pumps are getting higher and higher. In addition to continuing to improve the quality of conventional pumps and expanding the specifications of the pumps, the demand for pumps for conveying corrosive materials is increasing Large, such as the production of ethylene in ethylene cracking unit, polyethylene plant and polypropylene plant, chemical fiber production of PTA plant (terephthalic acid), polyester plant and polyester spinning plant, etc. Therefore, efforts should be made to develop corrosion-resistant technology. Stainless steel pump with corrosion-resistant, high strength, lightweight, long service life and other excellent features. In recent years, stainless steel pumps in shipbuilding, rail vehicles and other transportation industry has been widely used, with the machinery manufacturing industry, stainless steel pumps will have a broader application prospects. However, the growth rate of consumption gradually slowed down from an ultra-high-speed development stage with an average annual growth rate of over 30% to a steady development stage with a current growth rate of 6.43%.
