In recent years, with the increase of new construction and expansion projects of large refineries and many small and medium-sized refineries, the demand for petrochemical pumps has been increasing. To meet the new market demand, chemical pump manufacturers are actively improving product design and production technology and expanding production capacity. However, there are some technical details that need attention in the process.
According to different process routes, the main units in refineries are atmospheric distillation, vacuum distillation, catalytic cracking, hydrocracking, delayed coking, etc.
According to the above technological process, the most important pumps in refineries are the primary distillation tower bottom pumps, atmospheric tower bottom pumps, vacuum tower bottom pumps, slurry pumps, hydrogenation feed pumps, coke discharge pumps (coke removal pumps), etc. These pumps mainly transport flammable, explosive or toxic dangerous liquids, some medium temperatures as high as 400 C, and some contain solid particles, so the materials are required to have good corrosion resistance and resistance. Abrasion capacity, the pump must also have high reliability, long-term safe operation.
oil-refining pump are used to transport fluid from one location to another. Various types of refinery pumps are centrifugal pumps, rotary pumps and reciprocating pumps. Different types of refining pumps are integrated in the refining system for specific purposes, and play an important role in purifying and transporting different fluids.
The oil-refining pump market is subdivided according to capacity, product type, application and pump characteristics. These main subdivisions are further divided into subdivisions.
According to capacity, the market is divided into small (up to 500 gallons per minute), medium (500-1000 gallons per minute) and high (over 1000 gallons per minute). On the basis of product types, the oil-refining pump market is divided into reciprocating pumps, centrifugal pumps and rotary pumps.
Through application, the oil-refining pump market is divided into refining process, water circulation, special use and water/wastewater. According to the characteristics of pumps, the refining market includes standard pumps, engineering pumps and special pumps.
