First, the operating procedures: /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
1. Check the mechanical and electrical appliances before driving; check whether the connecting bolts can be loose, whether the smooth points are smooth or not; whether the transmission equipment can be normal and reliable; the protective equipment is intact; whether the electrical appearance is active; the motor carbon brush touches outstandingly .
2, drive a week; check the equipment changes some or around there are obstacles; and eliminate. When the start is banned from standing.
3. After checking the error; press the start button to start the motor; pay attention to the current change. The ball mill should not be connected twice in succession; the first time and the second time are more than 5 minutes; if it is the third start; it is necessary to cooperate with the electrician and fitter to view After; can be started. Must not be with other equipment; to interweave start; avoid tripping.
4. After the ball mill is in normal operation; the rules of water supply, ore supply, and steel ball should be strictly pressed; the overload operation should be stopped; the idling time should not exceed 15 minutes; avoid the damage of the liner.
5, in the operation should pay attention to check whether the cylinder can leak; carefully investigate whether the current, voltage, feeding, water supply can be normal; every half an hour to check the motor and spindle temperature is not more than 60 ° С; find problems in time to deal with.
6. During the operation, it is necessary to pay attention to whether the hollow shaft and oil ring can be changed with oil; whether the temperature of the hollow shaft can be normal; if the hollow shaft is found to be hot; when it is near burning, the forced cooling method should be adopted immediately; no parking should be stopped immediately; avoid formation "Holding the axis". Pay attention to the oil quantity and temperature of each smooth part together; keep on time.
7. Before the ball mill is parked, stop the feeding to the mine; after the finished concentrate is disposed of; stop the water supply. Press the parking button; pull down the electric brake.
8. When there is no power failure, the first step is to pull down the knife gate; press the stop button; stop the feeding and water supply.
9, after parking; finishing equipment and environmental sanitation; to ensure civilized production.
Second, the protection procedures:
1. The operation and protection personnel of the ball mushroom machine should understand the structural performance of the damaged equipment and the title, standard and effect of each component.
2. The operator should follow the “four-set†criterion; the requirements of each part marked by the smooth diagram are smooth; the untreated waste oil should not be used;
3, pay attention to check the bearing temperature of each part does not exceed 60 °C; and check whether the bolts in each part are loose; whether there is abnormal movement; whether the ore supply water can be uniform; whether the cylinder has the appearance of slurry leakage; whether the motor current and voltage can be normal. Some protective covers can be used without any problems.
4. Adhere to the sanitation and hygiene of the equipment; except for some operations; others must be disposed of at any time.
Third, maintenance procedures. ㄒ唬12. 煨拗芷冢 1, after 1 month, 2, minor repair 1 3 months, 3, medium repair 12 24 months, 4, overhaul 60 120 months.
Ǘ12.煨煨1, repaired: first look at the amount of oil, adjust the gaps of each part; consolidate the bolts; replace a single liner or view the wear of the liner; repair the feeder.
2, minor repair: check the wear condition of the tooth surface; check the wear condition of the lining; replace if necessary.
3, medium repair: replace some parts of the feed; replace the transmission of small tooth runners and bearings; reducer crash view. The gears can be adjusted according to the situation in the 35 years of operation; the hollow shaft operation should be measured in 35 years.
4, overhaul: collapse to clear, measure; according to wear conditions; repair or replace large gears, hollow shafts, spherical tiles, drive shafts, pinions and cylinders; repair and replace electrical components; electrical equipment after overhaul; Inspection work.
ㄈ12. 曜薇曜1, the processing surface on the two bearing bases is on the same horizontal plane; the intermediate distance tolerance is 1mm; the longitudinal middle line non-parallelism error is 0. 5mm; the horizontal middle line error is 0. 5mm.
2, the spherical touch surface of the tile seat should be evenly connected, not less than 12 points per 5050mm2, the hollow axis and the tile touch surface should be 90° 100° per square inch not less than 2 points; the gap between the journal and the bearing is similar same.
3. The cooperation surface between the cylinder flange and the front end cover should ensure excellent touch; the shims are forbidden; the different axial tolerances of the two hollow shafts are less than 0. 8mm. The large ring gear and the end cap of the cylinder are adjusted when the joint device is adjusted. ; should be consolidated thrust; top positioning pin; radial ringing of the ring gear is not greater than 0. 5mm; axial rocking is not greater than 0. 84mm.
4. When lining the device, first install the end cover; the lining of the cylinder should start from the raw tooth; according to the requirements of the device; the screws should be evenly tightened; no water leakage. The rubber lining should cooperate without gaps; Block with a sponge.
5, the middle line of the pinion gear and the middle line of the large gear should be parallel; the error is not more than 0. 2mm. The top of the tooth gap is 1/4 modulus; the flank clearance is 1.06-----1. 8mm; The touch area is not less than 50% of the tooth length; 40% of the tooth height.
6. The transmission coupling of the reducer, motor and drive shaft should adhere to a high degree of coaxiality; the different axial degrees of the intermediate line are not greater than 0.3 mm; the inclination of the intermediate line is less than 1/1000.
. Model (18) trace 1, bearing wear is greater than 1/3 of its thickness.
2. The wear of the pinion surface should not be greater than 30% of the tooth thickness; the wear of the large ring gear tooth surface is greater than 25% of the tooth thickness; it can be used on the reverse side; it should be discarded when it is 1/2.
3, the deformation of the ring gear rim distortion should not be greater than 7. 5mm.
4. The outer surface of the hollow shaft is grooved, stained or partially worn on the inner circular surface to cause deformation of the hollow shaft; the crack and other conditions should be replaced.
