混凝土攪拌車的出現,不僅節省了人力,更節省了時間,重要的是物料得到了充分的均勻的混合。但是由于該設備承載量較好,配料較多,那么我們又該怎么掌握配料的誤差呢?接下來簡單講一下。
The appearance of concrete mixer not only saves manpower, but also saves time. The important thing is that the materials are fully and evenly mixed. However, due to the good bearing capacity of the equipment and more ingredients, how can we master the error of ingredients? Let's talk about it briefly.
應檢查機械部件是否對稱量偏差有影響。如果在稱量產生被稱物料的實際重量比電腦稱量顯示值大的情況。應先將這種可能性排除,確保重力傳感器的變形或秤斗在重力方向的位移未受限制,不會引起稱過程中,重力傳感器的變形或秤斗在重力方向的位移受到限制,就會量偏差。
Check whether the mechanical parts are affected by the symmetry deviation. If the actual weight of the weighed material produced during weighing is greater than the computer weighing display value. This possibility should be ruled out first to ensure that the deformation of the gravity sensor or the displacement of the scale bucket in the gravity direction are not limited, which will not cause the deformation of the gravity sensor or the displacement of the scale bucket in the gravity direction to be limited during the weighing process, which will lead to the deviation of the measurement.
對標定合格的計量配料倉進行控制誤差的檢驗,實際上是對加料裝置的控制準確度的檢驗。其中包括機械結構和儀表運行程序的科學性、可靠性、穩定性。
The inspection of the control error of the calibrated metering batching bin is actually the inspection of the control accuracy of the feeding device. It includes the scientificity, reliability and stability of mechanical structure and instrument operation procedure.
可以按各種物料的工藝配料量,按配料順序,逐個進行核對檢驗。允許對有關參數進行調整,直滿足配料準確度要求。建議是采用滿量程實物較稱那樣誤差很小,但根據現場情況而定。總之,越接近滿量程度誤差越小。
It can be checked and inspected one by one according to the process batching quantity and batching sequence of various materials. It is allowed to adjust relevant parameters until the batching accuracy requirements are met. It is recommended to use full-scale physical weighing, which has a small error, but it depends on the site conditions. In short, the closer to full scale, the smaller the error.
