砼搅拌站称量装置根据其结构一般可分为杠杆系统、称量斗、卸料机构等。其中杠杆系统是直接影响称量精度部分,所以,在设计过程中对它进行误差分析是很有必要的。如图是一种水泥称量装置的杠杆系统示意图。由于杠杆系统在加工及装配过程中均有偏差,所以使杠杆比产生误差而影响精度。 砼 Mixing station weighing devices can generally be divided into lever systems, weighing hoppers, unloading mechanisms, etc. according to their structure. Among them, the leverage system directly affects the weighing accuracy. Therefore, it is necessary to analyze the error in the design process. The figure is a schematic diagram of a lever system of a cement weighing device. Because the leverage system has deviations in both machining and assembly, the leverage ratio affects the accuracy.
