Technical Field

[0001] The present invention belongs to the technical field of variable frequency control of feed pumps, and in particular relates to an anti-sway control device based on variable frequency control of a needle coke feed pump. Background Art

[0002] Feeding refers to the action or process of sending the material to be processed forward or refers to the continuous feeding of the workpiece processed by the machine tool. The suction pump, commonly known as the barrel pump, is a pump mainly used to transport various acids, alkalis, solvents, additives, auxiliary agents, oils and other medium and low viscosity fluids in barrels or containers to automatically supply materials. Frequency conversion is to change the power supply frequency, thereby adjusting the load, reducing power consumption, reducing losses, and extending the service life of the equipment. The core of frequency conversion technology is the frequency converter, which realizes the automatic adjustment of the motor operating speed by converting the power supply frequency, thereby controlling the feeding speed of the feed pump.

[0003] However, the existing anti-sway control equipment based on frequency conversion control of needle coke feed pump still has problems such as large shaking of the top of the box when it is impacted, poor impact resistance and poor fixing effect on the side.
