Description

Technical Field

[0001] The invention belongs to the technical field of feeding systems, in particular to an automatic feeding system with a gear pump. Background Art

[0002] A pump is a mechanical device used to transport liquid from one place to another. A pump automatic feeding system is a device that integrates pumping and automation control technology. It is used to automatically transport materials such as liquids or slurries to the production process efficiently and accurately. It is usually composed of a centrifugal pump or a plunger pump, a controller, an actuator and a piping system, and is commonly used in the chemical industry.

[0003] The existing pump automatic feeding system has certain disadvantages when in use. When in use, the existing pump automatic feeding system adopts centrifugal pumps or plunger pumps for automatic feeding. The disadvantage of the automatic feeding system using a plunger pump is that the feeding has pulses, which is not smooth enough, and can also cause vibrations in longer pipelines, causing metal fatigue of the connected ferrule joints and eventually leading to leakage. The disadvantage of the automatic feeding system using a centrifugal pump is that the pressure is low and the head is low. When transporting to the top of the reactor at a height of more than ten meters, the flow rate and head do not meet the process requirements, and during use, residues from feeding are easily accumulated in the pipeline, affecting the feeding ratio and reaction, and failing to meet people's needs. Summary of the invention

[0004] The present invention aims to solve the technical problems existing in the prior art; to this end, the present invention proposes a gear pump automatic feeding system.
