一、使用注意事项
开机:先把移动小车定位(注开机后严禁移动小车),然后从最后一段皮带机开始(即石料落下那车皮带机),依次按顺序起动。小车上横皮带反方向操作?#21271;?#39035;先停机(运料中不可切换),如违反操作责任自负。
二、使用中常见问题及解决办法:
(1)、皮带跑偏:
皮带跑偏有多种因素,例天气(?#20174;?#22825;)或料潮湿、皮带机振动,落料偏位等,天气或料潮湿容易使大滚筒?#25176;?#25176;辊上沾上细料使滚筒加粗造成皮带跑偏,要时常检查是否有此现象及时清除细料。
皮带机振动容?#33258;?#25104;托辊支架固定螺丝松动,支架移位,使皮带跑偏,如发现,需将支架和大架之间夹角调成90度,把螺丝拧紧即可。
落料偏位要时常检查料斗与皮带的位置。
由复杂原因引起,可请厂?#26131;ㄒ等?#21592;调整。
(2)、皮带撕裂:
若有异物卡在滚筒中托辊上,皮带转动异物不动,将皮带纵向撕开,要时检查有没有异物落在皮带非工作面和检查小托辊是否损坏,如有应及时更换。如有此种情况,责任自负。
(3)、电动滚筒:
电动滚筒烧掉,有两个原因:1、缺电相,2、电动滚筒疲?#20572;?#21363;使用时间过长(连续使用1 5 个小时以上);此两项制造方概不负责,正常使用保修一年。
三、维修与保养
(1)皮带:如发观皮带有局部损坏应及时修补,避免影响整条皮带的使用寿命:
(2)托辊:托辊轴与筒之间要经常点机油保持托辊的灵活性:
(3)电动滚筒:每三个月加一次机?#20572;?#22810;少视机油损耗度。半年需更换一次机?#20572;?br />
(4)大滚筒:半年换一次轴承或视使用情况而定:
(5)机架:机架所有螺丝需时常检查,将松动螺丝拧紧。
输送带的贮存使用注意事项
1、输送带在运输和贮存中,应保持清洁,避免阳光直射,雨雪浸淋,防止与酸、碱、油类, 有机溶剂等影响橡胶质量的物质接触,并距离发热装置1米以外。
2、贮存时库房内温度宜保持在-1 50C-+400C之间,相对湿度宜保持在50-80%之间。
3、贮存中输送带须成卷放置,不得折叠,放置期间应每季翻动一次。
4、输送带运行速度不应大于5.0米/秒,运输块度大,磨损性大的物料和使用固定犁?#25176;?#26009;装 置时应尽量采用低速。超出规定速度?#20445;?#20250;影响胶带使用寿命。
5、运输机的传动滚筒直径与输送带布层的关系,传动滚筒改向滚筒的配套以及对托辊槽角的 要求,应根据运输机的设计规定,合理选取。
6、为减轻物料对胶带的冲击与磨损,给料方向应顺胶带的运行方向;物料下落到胶带上的落 差应尽量的减小;给料口应避开滚筒或托辊的正上方;胶带受料段应缩短托辊间距?#31570;?#21462; 缓冲措施。为防?#26500;?#30772;胶带,挡料装置、刮板清扫装置?#25176;?#26009;装置与胶带的接触部分应采 用硬度适?#35828;?#27233;胶板,不要采用夹有布层的胶带头。
7、输送带在使用中应注意以下事项:
A、避免托辊被物料覆盖,造成回转不灵,防止漏料卡于滚筒与胶带之间,注意活动部分 的润滑,但不得油污输送?#39304;?br />
B、力求避免带负荷启动。
C、胶带发生跑偏,应及时采取措施纠正。
D、发现胶带局部损伤应及时修补,以免扩大。
E、避免胶带遭受机架、支柱或块?#27425;?#26009;的阻?#20572;?#38450;止碰破扯裂。
Use one, the note
Boot: the mobile car first positioning (note after startup it is forbidden to move the car), and then start from the last section of the belt conveyor machine) (that is, the stone fall in the wagon, in turn, starting in sequence. The car in the opposite direction of horizontal belt operation must first stop (cannot be switch in material handling), such as violation of operating responsibility conceited.
Second, the use of common problems and solutions:
(1), belt running deviation:
Belt running deviation has a variety of factors, the weather (rain) or damp, belt machine vibration, blanking offset, such as weather or material on the wet easy to make the big drum and small roller on the drum is bold belt running deviation, fines should always check to see if there is this phenomenon timely removal of fine material.
Vibration cause of belt conveyor idler bracket screw loosening, stent displacement, make the belt running deviation, if found, will support and big Angle between 90 degrees, the screw can be.
Blanking offset should always check the position of the hopper and belt.
Caused by complicated reasons, but please send professional personnel adjustment.
(2), belt tear:
If there is foreign body on the card in the roller roller, belt rotating foreign body motionless, the belt longitudinal tear, to check for foreign material on belt when the working face and check whether the small roller damage, if any should be replaced in a timely manner. If you have this kind of situation, responsibility conceited.
(3), electric drum:
Electric drum burn, for two reasons: 1, the power shortage, 2, electric drum fatigue, which USES time is too long (more than 5 hours of continuous use 1); The two, the manufacturer is not responsible for normal use of the warranty for one year.
Third, repair and maintenance
(1) belt: such as hair view belt with local damage should be repaired in a timely manner, to avoid affect the service life of the belt:
(2) roller, roller and the tube always point between the oil roller to maintain the flexibility:
(3) electric drum: once every three months to add oil, how much depending on the degree of oil consumption. Half an year is need to change the oil:
(4) the big drum: six months in a bearing or depending on the usage:
(5) frame: frame all screws should be check regularly, will loose screw.
Conveyor belt storage use matters needing attention
1, the conveyor belt in transportation and storage, should be kept clean, avoid direct sunlight, rain and snow shower, prevent with acid, alkali, oil, organic solvent, affecting the quality of rubber material such as contact and distance heating device 1 metres away.
2, storage room temperature should be keep between 50 c - 1 + 400 c, relative humidity should be kept between 50-80%.
3, storage in the conveyor belt must be placed in rolls, not fold, should be placed during quarterly turn once.
4, conveyor belt running speed should not be more than 5.0 m/s, large transport blocks of abrasion resistant materials and using a fixed type plow discharge Should as far as possible when using low speed. Within the prescribed speed, will influence the service life of the tape.
5, the transmission roller conveyor, and the relationship between conveyor belt layers and the diameter of the transmission drum redirection roller supporting and requirement for roller groove Angle, should according to the regulations of the design of the conveyor, reasonable selection.
6, to reduce the material impact on tape and wear and tear, the feeding direction should be along the belt running direction; Difference in whereabouts to fall on the tape should be reduced; The feeding mouth to avoid roller or roller is directly above; Tape material section should shorten the roller spacing and buffer action. To prevent scraping the broken belt, keep-off device, scraper cleaning device, and discharging device with the contact part of the tape should be taken With suitable rubber hardness, do not use with layers of glue to take the lead.
7, conveyor belt in use should be paid attention to the following:
A, avoid rollers is covered by the material, causing the rotation is ineffective, prevent leakage of material between the roller and the tape, pay attention to the lubrication activities section, but not oil conveying Fei.
B, makes every effort to avoid loading start.
C, belt running deviation, timely measures should be taken to correct.
D, find tape local damage should be repaired in a timely manner, so as not to expand.
E, avoid tape rack, pillar or block material retardation, prevent touch broken rip.
