Debugging of ready mixed concrete batching plant and calibration of its weighing system:

1) Turn on the main power supply, adjust the corresponding air switch or the current value of each load protection according to the size of each load; Close the main switch of the console to observe whether the instrument and computer display are normal.

2) Open the air compressor to make the pressure of the compressed air system reach 0.7MP. Operate the solenoid valves to control the torsion, check whether the electric solenoid valves and cylinders are working properly, and adjust the fuel supply of each oil mist.

3) Pull the production mode switch to the manual position, point the corresponding twist on the operating table, move the loads one by one, check whether the feeding, proportioning, lifting, mixing, unloading and the corresponding gas, water and admixture routes are running normally and smoothly, and whether the direction is correct. If the direction of the motor and screw machine is different from the direction indicated, the machine must stop immediately to adjust the phase. Up and down, check whether the upper and lower limit switches are flexible, accurate and effective.

4) Before scaling, the fixed bolts between the bucket and the frame should be removed so that the sensor is in a stress state.

5) Set the parameters of the scales, calibrate them with weights. The weights of the scales should be as close as possible to the range of the scales. After calibration, check the accuracy of the scales with known weights.
