What Is The Development Prospect Of Thermal Insulation Chemical Pump Market

Apr 29, 2022

The chemical pump produced by the manufacturing and protection pump industry is the rotating equipment with the largest consumption in petrochemical production devices. It transports various liquid media such as crude oil, refined oil, chemical raw materials, intermediate products and finished products to other places, just as the human heart transports blood. At the same time, the pressure of the medium conveyed by the chemical pump is from negative pressure to 300mpa, and the temperature is from minus 140 ℃ to nearly 500 ℃ above zero. Some media are viscous, and some also contain solid particles. Most of the conveying media are corrosive, while the chemical pump is the equipment with the most energy consumption, and the pump power consumption accounts for about 50% of the power consumption of the whole plant.

Statistical data of thermal insulation chemical pump:

According to statistics, a medium-sized refinery has more than 1000 pumps, of which centrifugal pumps account for 83%, reciprocating pumps account for 6%, gear pumps account for 3%, and the rest are screw pumps and vacuum pumps. A petrochemical plant has more than 2000 pumps, of which centrifugal pumps account for 45%, gear pumps account for 23%, reciprocating pumps and screw pumps account for 12% and shielded pumps account for 6%. These pumps are generally driven by motors.

With the continuous development of petrochemical industry technology and scale, the requirements for petrochemical pumps getting higher and higher. In addition to continuing to improve the quality of conventional pumps and expand the specifications and varieties, the demand for pumps conveying corrosive materials is increasing, such as ethylene cracking unit, polyethylene unit and polypropylene unit in ethylene production; PTA device, polyester device and polyester spinning device, acrylonitrile and fat feeding device in chemical fiber production. Therefore, efforts should be made to develop the technology of corrosion-resistant pumps.

The thermal insulation chemical pump will have a great impact on petrochemical production and construction with its performance, quality and service life. With the domestic pump industry to speed up the pace of reform, aim at the largest market, adjust the product structure and improve the technical and management level, we must first improve the degree of standardization, serialization and generalization of products.
