12 Checking items before starting concrete batching plant
Firstly, check whether there is anyone constructing or working in the equipment (mixing station/belt conveyor/bucket/main engine, etc.) and the surrounding area. After confirming that the mixing station will not endanger the construction personnel, the subsequent operations can be carried out. Be careful about this. Don't take it for granted and think that there is nothing wrong. You must look around and check it by yourself.
1. Check whether the switches of the electrical console are in the normal position
2. Idling check whether the horizontal belt conveyor and the inclined belt conveyor are operating normally. It is necessary to look at the monitor or walk out of the operating room to observe.
3. Before the test run of the main engine, make sure that there is no material and other debris in the main engine; it is best to remove the main engine belt cover, pull the V-belt pulley, and check whether the main engine can easily rotate; then add water to the main engine to check its sound, vibration, and no load. Whether the current and other parameters are normal;
4. Check whether the centralized lubricating oil pump of the mixer is working correctly;
5. Check whether the lubricating oil of the mixing host and the running parts of the mixing station is sufficient;
6. Check whether the connecting bolts of each connecting part are tight;
7. Check whether the manual butterfly valve of the powder tank is open;
8. Check whether the gas supply, water, and admixture pipelines are normal;
9. Check whether the aggregate, powder, water, and additives are sufficient;
10. Before operating the mixing plant, check whether the switches are all closed in the strong electric cabinet;
11.Turn on the power knob of the console, the power indicator should be on at this time, press the air compressor start button on the cabinet door, and check whether the air pressure is above 0.4MPa;
12. Turn on the power of the computer, start the computer and run the monitoring program, set the formula ratio according to the "computer operation", and prepare to start producing concrete.
