The inspection and maintenance of belt bucket elevator

The belt bucket elevator inspection and maintenance - 2020 01 - 15 Wang Zhanguang ( Jiaozuo strong cement) Tape winding machine has become a ideal promotion conveying equipment, powder material substitution pneumatic lifting transport equipment for many years, such as how to preheater into the raw material, grinding and cement grinding powder material conveying, high output, low failure rate, high efficiency, is widely used in cement industry. Today is briefly talk about tape winding machine inspection and maintenance. Take elevator structure composition and working principle: take elevator mainly composed of motor, reducer, coupling on roller, sprocket, transmission system, the nose, among the next frame shell, shell, shell tape, bucket, rise up, etc. Work, motor, reducer through coupling drive head roller rotation, infinite cylinder to drive the belt do sports. Elevator into the material on the bottom, in part, directly into the dou inside, under the part into the base casing, when fixed in the belt of the sprockets, just take out the material, and the discharging mouth discharge. Take elevator inspection need to pay attention to the following: 1, check the belt bucket elevator drive installed base whether have damage, crack, whether the bolt is loose. 2, check for damage to stop signs, leakage, noise is normal. 3, check the belt bucket elevator speed reducer for leakage, lubricating oil condition. 4, check all whether there is abnormal sound or vibration inside the transmission system components, each point temperature is normal. 5, check the discharging of material flow of the valve is normal, is ever accumulation or congestion and returns, check the hoist inside the chassis is slightly negative, whether local grey. 6, check all inspection door and check whether the port is closed, is properly sealed. 7, check the belt bucket elevator in the tension device if there were any abnormal noise or vibration. 8, check the status of bucket elevator chassis, is there a dozen give sound, whether there are signs of wear or damage. 9, check the running deviation, speed switch, judge whether need to adjust. 10, by electric current, feeding judging hoist loads. According to the inspection situation, elevator repair and maintenance of the following: 1, the sprocket wheel up and down bearing oil; 2, the reducer oil to oil the appropriate location. 3, if discover motor, reducer, have abnormal sound non-return device, bearing, high temperature, two motor current difference is more, when analyzing the reason stop processing; 4, when the hoist bearing bolt looseness, should be timely fastening; 5, and found that the feed opening not free, in return, should be timely find out the reason, opening up in time. 6, the hoist must run under negative pressure environment, the head must receive dust, dust collecting hole if take a hoist shell ash, should be timely increase negative pressure regulating valve, dust or seal housing to avoid overflow. 7, if discover the hoist and resistance to friction pendulum support, should be in its clearance to add lining, limiting its momentum, but must guarantee that in the height direction of the free list, to ensure the discharging mouth is flexible connection. 8, in the tape when installation should pay attention to, the face of positive and negative of adhesive tape, transverse steel wire surface ( Laceration resistant layer) Contact with the drum, without lateral steel wire surface mounted to the hopper. 9, tape joint when installation, must guarantee the parallelism of adhesive tape, belt clip bolt shall be installed in accordance with the specification requirements of the tightening torque for installation, clamping. 10, regular check hopper bolt, bolt tightness to large flat plane surface flush with tape or sink no more than 1 mm. 11, weight or rise up, should be the basic level, and take care of the belt in the middle of the run. 12, reducer, transmission shaft lock should also regularly check, observe whether loose or damaged. 13, driving wheel to check once every six months, observe the rubber roller surface wear, found that the problem handled in time, is bound to screw fastening and partial loss. The bucket of 14, check and found the hopper wear serious leak is expected to change in time, connecting bolts fall off or broken, supplement or replacement in a timely manner. 15, often anchor steel structure and corrosion situation, found that can influence the situation of the heat bilges cold shrink is not normal, handle in time. Above is take elevator inspection maintenance of general knowledge, summary is not comprehensive, or have a deficiency, please correct me criticism. Thank you very much! （ Source: wisdom cement)
