Water is one of the indispensable raw materials for the production of concrete in the mixing station. However, with the improvement of the concrete quality requirements of the engineering construction, the precision of the water used in the mixing station must be more strictly controlled. At this time, a water metering system is needed.
However, in order to save the initial investment funds, many customers have omitted the water weighing system and can mix the concrete without using the water weighing system, but there are great hidden dangers.
Not using a single water weighing system can reduce part of the investment of the concrete mixing station, which can save about 7,000 yuan. However, if you do not use a water weighing system to add water to the mixing drum, you must use a time node to add water to the mixing drum at a certain time interval. At this time, the water addition and strong mixing time will be increased, and the concrete model will be unstable. . It can be seen that although not using a water weighing system can save some investment, it will increase the mixing time of concrete and affect the stability of concrete, which is not a wise choice.
Having said that, many readers must have become interested in the water weighing system of the concrete mixing station, so what exactly is it?
Water weighing system is mainly composed of water scale bucket, sensor, valve and so on. Among them, the sensor has an unbalance compensation function, which can realize coarse and precise weighing. Its function is to weigh the water for stirring. The schematic diagram of the water weighing system of the concrete mixing station is as follows:
1.Sensor 2.Water scale bucket 3.Butterfly valve
The water scale bucket is connected to the sensor through the connection base. The sensor generates a signal and outputs an amplified signal, which is compared with a predetermined value. When the water quantity reaches the predetermined value, the water supply is stopped and the water weighing is completed. When the host needs to add water for stirring, the valve at the bottom of the water scale bucket opens automatically, and the water directly flows into (or is pumped into) the mixing cylinder.
