Description

Technical Field

[0001] The invention relates to the technical field of peristaltic pumps, in particular to a peristaltic pump capable of synchronous delivery. Background Art

[0002] Peristaltic pumps have high-precision flow control functions and are suitable for accurate metering of various fluids. They are pollution-free and easy to maintain. They are widely used in chemical, pharmaceutical, food and other fields, as well as in analytical instruments to meet the stringent and precise quantitative delivery requirements.

[0003] In the process of laboratory research and development, peristaltic pumps are often used in situations such as cell tissue transportation, specimen decolorization, perfusion, liquid chromatography analysis, and the transportation of acidic or alkaline solutions. Through the continuous squeezing and release of the roller, a continuous peristaltic wave is formed to push the liquid from the feed port to the discharge port to achieve continuous liquid transportation. In the past, peristaltic pumps were designed as one-way channels. When guiding the flow of liquid, in order to ensure the stable transportation of the flow, the flow must be controlled within a certain range. If the delivery flow is too large, it will not only lead to a decrease in delivery efficiency, but the one-way flow design will also affect the overall delivery effect.

[0004] Therefore, the above-mentioned existing peristaltic pump is designed as a unidirectional channel. When guiding the fluid delivery, in order to ensure the stable delivery of the flow, the flow must be controlled within a certain range. If the delivery flow is too large, it will not only lead to a decrease in the delivery efficiency, but the unidirectional flow design will also affect the overall delivery effect. A peristaltic pump that can deliver synchronously can be designed to increase modularity and multi-channel design to ensure long-term stability and reliability. Summary of the invention

[0005] In order to overcome the problem that the existing peristaltic pump is designed as a one-way channel, when guiding the fluid delivery, in order to ensure the stable delivery of the flow, the flow rate must be controlled within a certain range. If the delivery flow rate is too large, it will not only lead to a decrease in delivery efficiency, but the one-way flow design will also affect the overall delivery effect.

At the same time, it also has the function of an external PLC central controller to achieve bus control. The phase detection box is located at the side end of the box, which is used to start and control synchronous rotation monitoring to ensure that each channel maintains strict phase consistency when transporting liquid.
