Check the lubrication system, the oil level and oil quality of the hydraulic station, and check whether the oil temperature, oil pump, cooler, filter and pipeline instrument are in good condition in winter. Whether the pipeline valve is consistent with the oil pump to be opened, and whether the cooling water is unblocked in the summer.
Check the transmission mechanism, motor, coupling, horizontal shaft, bolts for looseness, whether the motor wiring is intact, and whether the horizontal shaft lubricating oil tube is intact or not.
Check the rack, spring, bolts for looseness, lock the cylinder tubing for leaks, lock the oil pressure is appropriate, the pressure of the lock cylinder is appropriate, it is strictly prohibited to start the machine without locking, dust cover, down Whether the mine funnel and locking jaws are intact.
Manually check whether there is any antimony ore phenomenon in the crushing chamber, and listen to the sound of the size of the bevel gear. Check if the dust water is clear and adjust the dust flow.
Check the operation box, voltmeter, and current.
Second, the boot and equipment operation check
1. When the power-on command is received, switch the operation card and close the power switch to see if the voltage is within the specified reading range.
2. Before starting the oil pump in winter, first heat it to 20 °C -25 °C, then start the oil pump motor, adjust the oil pressure, the oil pump pressure is not less than 0.2MPa. The oil supply pressure is 0.08-0.15 MPa. Check the pipeline and the valve for leaks. Check whether the oil supply at each lubrication point is suitable and whether the oil return is normal.
3. Before starting the machine, confirm whether there are pedestrians and work around the equipment. After confirming the error, turn on the bell and turn on the power. After starting the power, first observe whether the no-load current is normal. Observe whether the operation of the transmission mechanism is stable and no noise, the oil supply in each oil channel is normal and there is no leakage, the main engine runs smoothly, the rotating speed of the moving cone is within the specified range, and the ore is evenly fed;
4. After the mine is observed, the current change is within the specified range. Listen to the gear teeth of the transmission mechanism for noise, whether the operation is stable, whether the sound in the crushing chamber is normal, and whether the whole machine is running smoothly;
5. Check the operation of the equipment every half hour, check whether the oil pressure and current are normal, check whether the dustproof water and cooling water are unblocked, check whether there is any antimony ore in the crushing chamber, whether the funnel and the conveyor belt are in good condition, observe all places. Whether the bolts are loose or not.
Third, stop
Stop the mine first. When it is confirmed that there is no mine in the crushing chamber, stop the main machine, stop the crushing first, and then stop the crushing after 10-20 minutes. After the host stops, stop the oil pump, turn off the cooling water, turn off the dust water, and turn off the power.
