The TD-B series belt conveyor is designed by Chongqing Longjian Industrial Group Co., Ltd. with a new combination of structural parts, which is convenient for transportation and installation. It can provide on-site production and installation according to customer needs, saving installation costs. It has been widely used in various types of gravel yards, ore sorting, commercial mixing stations, building aggregates, coal sorting and other fields.

        As a common transportation equipment, the senior editor of Chongqing Longjian Industrial Group recommends that in practical applications, you need to strengthen the mastery of its use, repair and maintenance points to better promote its performance.

       1. Correct use of belt conveyor

       1. Correctly grasp the electrical control method of the belt conveyor

       The belt conveyor is mainly operated by electrical control, so it must have a basic understanding of its electrical control. Generally speaking, there are three control methods: electromagnetic starter, electromagnetic soft starter and frequency converter. And these three control methods are dedicated controllers with strong flameproof performance and strong safety performance

       2. Pay attention to the protection function of the belt conveyor. During the operation of the belt conveyor, it has many protection functions, mainly for comprehensive protection of short circuit and phase failure, overload and leakage, etc. At the same time, it can also detect and block short circuit between poles. Protection against coal, smoke, deviation, and surface tearing.

       3. Grasp the use location of belt conveyor

       1) When using in the fully mechanized mining face, the belt conveyor is mainly used to transport the coal to the mining area, and a belt conveyor is provided under the transportation lane of the coal mining face. The end of the belt conveyor and the reprint The position of the machine head is overlapped, while the head is overlapped with the belt conveyor in the mining area, and the tail can automatically expand and contract, which effectively promotes the improvement of coal mining work efficiency.

        2) When working in the general mining face, the belt conveyor is mainly used to transport the coal from the coal face to the mining area, and it is arranged in the transportation channel of the coal face. Lap, and the head is overlapped with the belt conveyor in the mining area.

        3). When used in the tunneling surface, because the capacity of the belt conveyor is small, it is mainly arranged in the transportation channel of the tunneling surface, and its tail is overlapped with the head of the tunneling machine, and the head Then it overlaps with the belt conveyor in the mining area.

        4) When used in a centralized transportation line, there are two main cases. One case is to transport the coal in each mining area to the coal bunker in the centralized mining area with a belt conveyor, and another is to transport the coal in the coal bunker in the centralized mining area to the coal bunker with Coal bunker on the ground. In actual use, it not only has the advantages of long distance and large transportation volume, but also has high power and automatic tension and adjustment, so as to better monitor the running state of the belt conveyor, promote its transportation performance and transportation efficiency Improvement.

        Second, the main points of daily repair and maintenance

       1. Main technical points for maintenance of the belt conveyor During the operation of the belt conveyor, the common faults are mainly as follows: ①The main roller does not rotate; ②The conveyor is boring; ③The belt is slipping; ④The belt runs Partial; ⑤ belt surface wear; ⑥ over temperature; ⑦ smoke.

       As far as fault ① is concerned, it is mainly because after the belt conveyor starts normally, although the motor is running normally, the main drive roller does not rotate. The root cause is mainly due to the failure of the reducer and hydraulic coupler. In order to strengthen its treatment, it is necessary to strengthen its maintenance. If the maintenance is not good, it should be replaced in time to ensure its normal operation. But in addition to this reason, there is also a belt conveyor that does not start properly and the motor does not operate normally, which will also cause the main drive roller to not rotate, which is mostly due to the vacuum electromagnetic soft starter and motor failure Therefore, it is necessary to strengthen its maintenance and replacement.

       From the point of view of fault ②, it is mainly caused by insufficient voltage and phase imbalance of the electrical fault system, plus heavy load and uneven installation. This requires strengthening the maintenance of its power supply system and straightening the conveyor after reducing the load on the conveyor.

       From the point of view of fault ③, it is mainly caused by insufficient tension of the belt surface and serious wear of the driving roller. This requires repairing the tension device to ensure that its tightness is improved, and repairing or even replacing the driving roller.

       From the point of view of fault ④, it mainly focuses on the situation of belt surface elasticity, installation of transport aircraft, and loading is not in the center, etc., and strengthens its maintenance and research, and carries out loading in strict accordance with the specifications.

       From the point of view of the fault ⑤, it is mainly to repair the problems of insufficient tension of the belt surface and the non-rotation of the upper and lower idlers to ensure that the tension is controlled.

       From the point of view of faults ⑥ and ⑦, it is mainly to effectively improve the protection performance of over-temperature, smoke and coal piles, and timely replace and repair damaged parts.

        2. Main points of maintenance technology When performing maintenance, it is mainly to strengthen the maintenance of the electrical system, rotating parts and some parts, and master the technical points. For example, in order to strengthen the maintenance of the electrical system, it is mainly to strengthen the maintenance of its cables and starters, improve the insulation of the cable, and strengthen its maintenance in terms of moisture and scratch resistance, and strengthen the protection test of the comprehensive protector, etc. .

       In summary, the use, repair and maintenance of the belt conveyor is a very important task. Chongqing Longjian Industrial Group Co., Ltd. reminds you: In order to better promote the performance improvement of the belt conveyor, you must master its technical points in the use, repair and maintenance links to ensure the safety and efficiency of the entire transportation process.
