Mixing truck and metering system cannot be missing in the concrete mixing plant. Without the metering system, all links of the concrete mixing plant will become very troublesome. All kinds of raw materials need to be weighed first and then mixed, which will waste a lot of time and manpower. Therefore, the metering system also needs regular maintenance.

1.搅拌车，所有软连接的红胶管和称量斗中的波纹管在自然状态时不受拉力，否则会影响称量精度。

1. The mixer truck, all soft connected red rubber hoses and bellows in the weighing bucket will not be subject to tension in natural state, otherwise the weighing accuracy will be affected.

2.搅拌车，传感器安装好后，只能承受正压力(对于悬臂式或压式传感器)或正拉力(对于s型或拉式传感器)，不能承受扭矩。

2. After the sensor is installed, the mixer truck can only bear positive pressure (for cantilever or pressure sensor) or positive tension (for S-type or pull sensor), but can not bear torque

3.搅拌车，对于同一杆称， 其传感器(3个或4个)必须同型号同规格。因此安装传感器时一定要检查其铭牌上的内容是否一致，不同规格的传感器其外型有可能相同。

3. For the mixer truck, for the same rod scale, its sensors (3 or 4) must be of the same model and specification. Therefore, when installing the sensor, be sure to check whether the contents on the nameplate are consistent. The appearance of sensors of different specifications may be the same.

4.搅拌车，在称量斗上进行电焊作业时，必须断开控制电源，并将传感器短接或把电焊机的地线直接搭在称量斗上，避免焊接时过大的电流通过传感器而将其损坏。

4. When electric welding is carried out on the weighing bucket of the mixer truck, the control power supply must be disconnected, and the sensor must be short circuited or the ground wire of the electric welding machine must be directly laid on the weighing bucket to avoid damage caused by excessive current passing through the sensor during welding.

5.搅拌车，挝式传感器(s型)安装好后，需拧紧锁紧螺母，悬吊螺杆不能质住传感器槽型根部，即悬吊螺杆与型传感器槽型根部应留有10mm左右的间隙

5. After the installation of Lao type sensor (s type) in the mixer truck, the lock nut shall be tightened. The suspension screw cannot hold the groove root of the sensor, that is, there shall be a gap of about 10mm between the suspension screw and the groove root of the sensor
