Development trend of pump industry

2019/10/11


Energy conservation and emission reduction have become the main content of China's economic planning outline, especially in the industrial fields of power, steel, non-ferrous metals, petrochemical, water treatment of high energy companies, etc., and more stringent emission reduction policies have been put forward. As the industrial fluid transportation equipment, the pump occupies the main part of primary energy consumption, and energy management has become a problem to deal with doubts. The pump is usually driven by an electric motor.
 
 
 
The energy-saving method of the pump is to make the pump unit (pump, prime mover and some changes) in high-power operation state and reduce the external input power to a low point. Pump energy saving is a comprehensive skill, which involves energy saving of pump itself, system energy saving and operation. Energy saving significance of the pump industry: the power consumption of pumps is large. According to the general machinery industry association, the power consumption of pumps accounts for about China's power generation. The significance of pump power improvement for energy conservation and emission reduction. Article 4 the State encourages the selection of new technologies and methods and the improvement of the quality of property management and service by relying on scientific and technological progress. Power saving has always been one of the key operations of property equipment. China's urban construction continues to advance, with more and more high-level communities and properties, ensuring energy-saving pumps has become a hot product.

Structure of centrifugal pump


2023-06-29

The basic components of a centrifugal pump are a high-speed rotating impeller and a fixed worm-shaped pump casing. Usually centrifugal pumps have a number of (usually 4-12) backward curved vane impeller fastened to the pump shaft, and with the pump shaft driven by the motor for high-speed rotation.

After the centrifugal pump starts, the pump shaft will drive the impeller together for high-speed rotational movement, forcing the pre-filled liquid between the blades to rotate, under the action of inertia centrifugal force, the liquid from the center of the impeller to the periphery for radial movement.
