计量装置是搅拌站的重要组成部分。它必须确保各种材料配合比的准确性,使配成的混凝土能达到要求的强度、稠度和和易性。如果计量误差过大,就会影响混凝土的性能,甚至影响到建筑物的安全。因此,对计量装置的要求,首先是“准确”。一般称量器的自身精度都能达到0.5%,但由于物料下落时有冲击作用,给料装置与秤斗间有一定距离(即通常所说的“落差”)以及给料流量过大,控制系
The metering device is an important part of the mixing station. It must ensure the accuracy of the mix ratios of the various materials so that the finished concrete can achieve the required strength, consistency and workability. If the measurement error is too large, it will affect the performance of the concrete and even affect the safety of the building. Therefore, the requirements for the metering device are first “accurate”. Generally, the accuracy of the weigher can reach 0.5%, but due to the impact of the falling of the material, there is a certain distance between the feeding device and the hopper (the so-called “drop”) and the feed flow is too large. , Control system
