Digital quantitative continuous liquid injection pump

Abstract

The invention relates to a digital quantitative continuous liquid injection pump. The digital quantitative continuous liquid injection pump comprises a power source, a transmission system, an actuating mechanism and a control system, wherein the power source is used for outputting a rotary motion; the transmission system is used for changing the speed of the rotary motion output by the power source, then converting into a linear motion, then driving the actuating mechanism to suck liquid inside a container into a device and then draining the liquid at a liquid outlet; the control system is used for controlling the whole device, stepless speed change is realized by controlling impulse frequency, quantitative liquid injection is realized by controlling impulse quantity, the liquid injection precision is improved by introducing flow rate feedback, and overload protection is realized by introducing a pressure switch. The flow velocity of a fluid is controlled by adjusting the rotating speed of a stepper motor, so that the working pressure of the system is above the air separation pressure and saturated vapor pressure of the liquid, cavitation is prevented, and the work stability of the system is greatly improved, and the service life of the device is prolonged.

AI Technical Summary

Benefits of technology

This patented technology allows for accurate control over injecting fluids into different types of systems with minimal risk of damage or harm during operation. It also ensures that no air bubbles are introduced when filling containers with corrosion resistant materials like water because they don't affect their quality significantly. Additionally, it provides precise measurement results through an optical sensor used to measure how much fluid remains inside the container after being filled. Overall, this technology improves efficiency and accuracy while minimizing any potential issues such as leaks caused by gas bubble formation within the device itself.

Problems solved by technology

This patents describes different ways to improve the quality of liquids used in various industries like chemistry, metal production, paper manufacturing, pulp milling, oil drilling, and others where they work with these fluids. However, due to their unique properties - including being able to stop any sudden changes caused by external forces (vibration) without causing excessive heat generation and damaging them over longer periods, cavitations occur when changing pressures within the flow stream. These technical problem addressed by the present inventors relates specifically to improving the precision and speed of liquid delivery systems while avoiding issues related to frequent maintenance operations.
