Technical indicators of mixing equipment

We have already talked a lot about the basics of mixing equipment, and I believe that everyone understands it, but compared to today ’s problem, many friends may not be particularly aware of it.

The timing control structure is a device that controls the amount of water by controlling the length of the water supply time, that is, the amount of water pumped during the period from the start to the stop of the pump is controlled by a time relay. This device has a simple structure and low cost. However, the actual flow rate of the pump will change with the pressure change of the water supply tank, resulting in a large water supply error, generally about ± 2%, so it is only suitable for use in less demanding situations.

The measurement accuracy of decanted water is one of the important technical performance indicators of mixing equipment. Because the control of the water / cement ratio W / C is stable or not, it not only directly affects the construction technology such as concrete and workability, but also affects the final structural strength. Therefore, it has always received great attention from people, timing control of common control methods, Flow control and volume control in three control modes.
