Coal washing equipment jig is one of the important cleaning equipment in jigging coal plant. The working quality of the jig is directly related to the separation effect of the selected materials. In order to make the good working quality of the jig of the coal washing equipment, it is directly related to the separation effect of the selected materials. In order to keep the good working quality of the jig of the coal washing equipment, the jig of the coal washing equipment does not have quality obstacles or few faults Obstacles. Therefore, it is necessary to do a good job in the maintenance of the equipment
I. inspection and scrubbing equipment
1. Regular inspection Jig Wear condition of each compartment and discharge chamber;
2. Regularly check whether the discharge gate is not working or difficult to adjust, and check whether the valve cover is damaged.
3. For those using rotary air valve, it is necessary to check whether the adjusting sleeve fails, whether the air valve is loose, whether the chain and coupling are abnormal, and wipe the adjusting sleeve, motor and reducer regularly. For those using CNC air valve, regularly check whether each control valve, sealing ring and valve plate are worn, and regularly clean the air filter for control air and running air Observe the oil level of each atomizer and pay attention to the coal light display signal of each device running on the control panel;
4. The coal washing equipment should always check whether the chute and pipeline are unblocked, and whether the discharge channel in the jig is blocked by the screening materials;
5. Regularly check the air bag and remove the deposited dirt, regularly check whether the air valve is flexible, whether there is water leakage and wind leakage, and wash the air water valve regularly;
6. Regularly check the sieve plate of jig for friction, blockage or screw loosening, and clean the jig bed regularly.
1. Each shift should oil the valve, bearing bush, sprocket and reducer before starting; the lubricating oil system of control valve using numerical control air valve should be regularly oiled.
2. Oil the lubrication system of the self discharge detection device regularly.
1. It is strictly forbidden to use strong wind to agitate the bed without feeding, because the screen frame and sieve plate are seriously damaged;
If not, all the fuses in the bucket will be broken when the bucket is stopped or the motor will be burnt out again.
3. When the jigger of coal washing equipment is initially started, feed slowly.
