Problems solved by technology

[0004] At present, the commonly used flow detection method is artificial periodic weighing method. However, due to the limitation of working hours, during the long-term continuous operation process, there are artificial shutdowns, which cannot meet the requirements of fixed sampling frequency, and even miss some important results.
Moreover, the existing test methods require a large amount of test data, and the massive test data needs to be recorded by the experimenter and entered into the computer for statistics, analysis, and test report formation, which takes up a lot of manpower and material resources

Embodiment 1

[0041] The present application provides an automatic flow detection device for a transmission pump, including: a controller, a first pipeline, a first transmission pump, a first container and a balance, the inlet of the first pipeline is connected to the liquid input container, and the first A first outlet of a pipeline is connected to the first container, wherein the controller controls the balance to weigh the first container and record data, and the first pipeline is installed on the first transmission pump.

[0042] In this scheme, the controller can be understood as a device that controls other components, it can be an integrated controller, or it can be a controller composed of modules capable of realizing multiple functions. In this solution, the controller can control the start and stop of the first transfer pump, and control the data measurement and data recording of the balance.

[0043] A transfer pump can be understood as a pump body that transfers fluids, such as...

Embodiment 2

[0051] In the first embodiment, only a quantitative transmission path is added, and a balance is used to measure the fluid in the first container. The first transfer pump continues to transfer, but the capacity of the first container is fixed after all and cannot accommodate more fluid, so this embodiment also adds a pumping pipeline, which is to discharge the fluid in the first container at regular intervals to prevent the fluid from overflowing The first container will cause environmental pollution. In addition, it will also cause errors in measurement data.

[0052] The pumping pipeline in this embodiment includes: a second pipeline, a second transfer pump and a second container, the inlet of the second pipeline is connected to the first container, and the outlet of the second pipeline is connected to the The second container, the second pipeline is installed in the second transfer pump, and the second transfer pump is connected with the controller.

[0053] In this circui...

Embodiment 3

[0058] When testing the peristaltic pump, it is also necessary to measure the stability of the peristaltic pump, that is, whether the accuracy of the peristaltic pump will decrease after long-term continuous operation. This measurement requires long-term quantitative testing and does not need to obtain all measurement data. , such as every 2 hours, 4 hours or every 24 hours.

[0059] In response to this requirement, this embodiment also sets up a continuous circulation pipeline, that is, the pipeline inlet and pipeline outlet of the first transfer pump are placed in a container, so that the fluid transferred by the first transfer pump is always in the same The flow in the container, which can keep the peristaltic pump running normally, can also eliminate the need to measure the transmitted fluid data.

[0060] It should be noted that when the continuous circulation pipeline is running, the quantitative transmission pipeline is stopped. Therefore, in this embodiment, the first ...

Abstract

The embodiment of the invention discloses a transmission pump flow automatic detection device and method, the device comprises a controller, a first pipeline, a first transmission pump, a first container and a balance, an inlet of the first pipeline is connected with a liquid input end container, a first outlet of the first pipeline is connected with the first container, the controller controls the balance to weigh the first container and record data, and the first pipeline is installed in the first transmission pump. According to the scheme, the data can be automatically stored, the test data does not need to be manually recorded and imported, the labor time is saved, inaccurate calculation results caused by data recording and copying errors can be effectively avoided, and the working efficiency of experimenters is improved.

Description

technical field [0001] The present application relates to the technical field of transmission pumps, in particular to a device and method for automatic flow detection of transmission pumps. Background technique [0002] Peristaltic pump is a commonly used fluid conveying device, which has the advantages of no pollution, high precision, good sealing, and simple maintenance. Peristaltic pumps, including drives, pump heads, pump tubing or other accessories. The long-term stability of peristaltic pump flow rate is one of its main performance indicators. Therefore, the long-term stability test method of peristaltic pump flow rate is a commonly used and important test method. In the existing test method, fixed-period fixed-frequency sampling (that is, sampling after continuous operation for a certain period of time) is a key step in the test. . [0003] Peristaltic pump flow measurement generally adopts volume method or mass method. The volume method is calculated based on the...
