Problems solved by technology

[0002] In the prior art, the acceleration of centrifugal pumps generally requires the help of high-speed motors, and the power span of high-speed motors is small. If the centrifugal pump is to be adjusted at different speeds, high-speed motors with different speeds are needed, and high-speed motors are expensive. , the cost is high, so it is difficult to realize the high-power span operation of the centrifugal pump by using a high-speed motor to increase the speed of the centrifugal pump
[0003] In the high-speed operation of chemical centrifugal pumps, the two-stage bearing box is usually used to achieve the speed increase. The bearing box is large in size and high in cost and maintenance. Additional oil circuits and cooling equipment are required to ensure the normal operation of the gearbox.
[0004] To sum up, the main technical problems of centrifugal pumps in the prior art are: the centrifugal pump has a small speed increase span and high cost

Abstract

The invention relates to the technical field of centrifugal pumps, in particular to a centrifugal pump accelerating device and system to relieve the technical problem of smaller accelerating range of a centrifugal pump in the prior art. The centrifugal pump accelerating device comprises a drive mechanism and a belt pulley transmission mechanism, wherein a centrifugal pump and the drive mechanism are fixed on a bottom plate; the belt pulley transmission mechanism is located between the drive mechanism and the centrifugal pump, is used for connecting the drive mechanism and the centrifugal pump and comprises a driving belt pulley, a driven belt pulley and a transmission belt. The rotating speed of the centrifugal pump can be adjusted in a large range by controlling the transmission ratio of the driving belt pulley to the driven belt pulley and the rotating speed of the drive mechanism. The centrifugal pump accelerating device is simple in overall structure and realizes operation without an additional auxiliary device, thereby being lower in cost.
