Hydraulic jacking mechanism for liquid weighing container

Abstract

The invention relates to a hydraulic jacking mechanism for a liquid weighing container. A hydraulic system, separating type jacks, a container prying base and a synchronous distributor are included, wherein the container prying base is fixed to the bottom of the weighing container, and the plurality of separating type jacks are installed at the bottom of the container prying base, and are fixed tothe ground through jack fixing bases; hydraulic pipelines of the hydraulic system communicate with hydraulic cylinders of the separating type jacks through the synchronous distributor; an electronicscale is arranged at the position, between the separating type jack fixing bases, of the bottom of the container prying base; and the weighing container is separated from and attached to the electronic scale under the action of the hydraulic cylinders of the separating type jacks. According to the hydraulic jacking mechanism for the liquid weighing container, the hydraulic work principle is adopted, the weighing container is easily separated from the electronic scale, it is guaranteed that when testing media are injected into the weighing container, the weighing container and the electronic scale are in a separated state all the time, so that the impacting force of vertically downward testing fluid on the electronic scale can be eliminated, the electronic scale is fully protected, and theverification accuracy is improved.

Description

technical field [0001] The invention relates to a hydraulic jacking device, in particular to a hydraulic jacking mechanism for a liquid weighing container. Background technique [0002] The weighing container is the container used for weighing the test medium in the liquid flow standard device of the static mass method, and is placed on the upper part of the electronic scale. Measure the quality of the liquid medium in the weighing container in a static state within a predetermined time, and compare it with the indicated value to realize the verification. The weighing container of the existing device is generally placed directly on the upper part of the electronic scale for testing and weighing, and has no function of hanging off the scale for verification. When the device is verified, the test fluid in the pipeline produces a vertical downward impact force, which directly acts on the electronic scale, resulting in a strong impact force on the electronic scale, which affect...

AI Technical Summary

Problems solved by technology

When the device is verified, the test fluid in the pipeline produces a vertical downward impact force, which directly acts on the electronic scale, causing the electronic scale to receive a strong impact force, which affects the measurement error of the electronic scale and reduces the accuracy of the test.

At the same time, it is easy to cause the weighing sensor in the electronic scale to be damaged by impact, reducing the service life of the electronic scale
