The inspection and maintenance of belt conveyor

The inspection and maintenance of the belt conveyor - 2020 01 - 01 Wang Zhanguang ( Jiaozuo strong cement) Belt conveyor as general conveyor equipment, because of its low cost, great capacity, reliable operation, low operation cost, are widely used in various industries. Today is the inspection and maintenance of the belt conveyor, do a simple introduction, hope can have the purpose of communication. A structure belt conveyor, belt machine has several major components, the first is power, transmission parts, have a plenty of electric drum, have a plenty of reducer motor; The second is the rack, Angle steel, channel steel welding spell; The third is the roller, up and down, the upper part of multi-purpose trough type, lower return pinto roller; The fourth is the conveyor belt; And rose up, vertical rise out of tight, the tail has a screw up tight, car type device up; There are loading and unloading are; The last is the tail redirection roller, etc. Second, understanding the structure of the belt conveyor belt inspection content, inspection content is a deal. Is every part of belt conveyor view, concrete can be described as follows. 1. For the checking for the belt strap first to see the running deviation, what place running deviation; Second to see if whether belt belt edge burr and interface layer whether the mouth; The third view the belt is too loose even skid, etc. 2. Inspection of roller roller is belt support components, should be paid attention to in the inspection to see if there is not turn the roller, the ji ji croak loud roller, whether there is because of the roller bearing damage to jump back and forth, have already worn through the rollers, check whether the roller support is reliable, etc. 3. Up the checking if vertical device up tight, should check the drum drop space whether meet the requirements, check whether there are obstacles or on the way, whether the lubrication in place, etc. For the tail screw up tight, check to see if there is impact adjustment disorder, adjusting bolt is rust, etc. 4. Head to check the nose is the place of power transmission, to check whether the speed reducer, motor temperature is normal, noise, vibration and noise is normal. Coupling and examine whether the shield and reliable, and view the transmission load case. 5. Examine other aspects into the shoes whether appropriate, if there is a splashing and middle, the discharging mouth is smooth, the nose and if there is a risk grey situation such as feeding port. Check around equipment for unstable objects endanger safety equipment, health equipment are in good condition. 3, equipment maintenance when check equipment problems, should be resolved one by one, according to the content of inspection, one at a time processing. 1. The belt running deviation handling when found the belt running deviation, must be handled according to the concrete situation. Wandering between adjusted through rollers skew wandering, the lateral running deviation of self-aligning roller forward ( The leather belt movement direction) Fixed, straightening stabilized,; If the roller can not meet the requirements, when forward run partial section of the roller, can solve the problem. If blanking of wandering, is usually caused by blanking is not belt center, adjust the discharge location. If the tail running deviation is back running wide side bolt can rise. 2. Intermediate roller fault handling when found the middle roller scream or broken gong, generally is internal bearing damage, short downtime, can be replaced, or concentration change during downtime. If the roller turn, and belt friction, so it is easy to grinding roll leather wear, should be replaced as soon as possible. Find local lack of roller, cause splashing, when added in a timely manner. 3. Belt to beat bearing belt wave, if discover the return belt, belt tension bridle is insufficient or too many blanking, should reduce capacity or get a tight belt. 4. For the maintenance first see vibration of transmission, find out the vibration reasons, for example, if there are wear aprons, lower coupling that is bad for the, should be renewed; If the anchor is loose, should tighten the anchor bolts; If the abnormal vibration and noise of the gearbox, reducer internal existing problems, should be the collapse of the maintenance; If the motor vibration more belong to the bearing fault, should be replaced; If discover the drum belongs to bearing damage of unstable operation and so on. If discover motor, reducer, fever, should check the lubrication condition, timely supplement of lubricating oil; Health cleaning equipment, equipment cooling conditions. 5. Belt skid process if found that the vertical ramp were or disabled, must clean up, ensure belt tension bearings, need you may need to dig a hole. Found that the tail is loose, timely fastening, etc. 6. Belt of exception handling when found the belt edge burr to take off the line, must be cut off, prevent pulling, cause damage; When the joint was found at the layer, nailing in time, prevent pulling; Belt degumming is found, should arrange appropriate time to repair glue, etc. 7. Other aspects in a timely manner clean-up, come on site check to fill oil to equipment, and check whether the equipment is overloaded, etc. Unstable objects around the cleaning equipment in time, to prevent damage to equipment, timely clean the feeding and discharging mouth bad or jam, etc. Conclusion: the above is a summary of inspection maintenance in belt conveyor, due to the limited level, not comprehensive, also mistakes unavoidably, hope comment. Thank you very much! （ Source: wisdom cement)
