Measures for the effective operation of scraper conveyor

Measures for the effective operation of a scraper conveyor
1 . Maintaining scraper conveyor running in calm conditions straight
Scraper conveyor in both the horizontal and vertical directions are allowed a certain degree of 90 degree turn conveyor bending ( which is to adapt the work
Surface transportation and roadway design , and does not refer to any of the upper and lower body and horizontal bending is reasonable ) , but
Permissible bending there are certain limits. If the scraper conveyor Abduction " chicane ", the joint will bend chute
Angle is too large , resulting chute connections damaged by excessive force . Damage and lost connections after chute , chute
Lost control joints , bending joints appeared gap between the chute , coal tank leak in the 90 degree conveyor end , will increase the run
Resistance or blockage caused the accident . If the conveyor laying uneven , then the blade and chute chute lap joints
Wear and tear , increased transportation ? Line resistance and shorten life , and it will lead to the end of the shearer cutting face
Board and make it uneven .
2 . Enhance the effective running time
Throughput scraper conveyor is run by its efficiency and working time decision. In a certain situation loading
Under conditions of work , the higher utilization of equipment operation , greater throughput , the performance of the scraper conveyor full
Play a beneficial , is an effective way to improve the yield and economic benefit . Therefore, you want to do everything possible to run
Reduce downtime . Generally not allowed scraper conveyor -load operation , because not only shorten the effective operation of load
OK time, but also caused a waste of electricity and mechanical wear invalid . If the scraper conveyor at runtime hair
Fails, as long as the fault is no longer expanding range should try to take a temporary repair tools, equipment continue to maintain
Operation will be postponed to deal with incidents within classes or shift maintenance spare time , avoid downtime , extended
Effective long running time .
3 . Load reasonable
Load scraper conveyor should be possible to achieve rating to its full production capacity. Conveyor
The charging excessive overflow will feed chute and outside the labor spent in vain and power , and cause equipment over
Upload and mechanical damage ; charging too little , so that the scraper conveyor capacity can not give full play to increase exercise in futility loss
, It is not economical. In addition, the uniformity of the load is also very important, which is not only conducive to the economic operation of the device ,
And extend the useful life of the scraper conveyor components.
4 . Strengthen supply management
Power supply voltage drop can not be overrun because of the torque of the motor is proportional to the square of the same voltage , power
Depression can cause difficulty in starting the motor , fever and even burn . So, to shorten as much as possible from the power supply
Away , so that the power transformer as close to the device.
5 . Timely maintenance and repair
By good standard scraper conveyor for maintenance and repair and maintain equipment in good condition and in good working
For the state.
