How to install and maintain belt conveyors




A belt conveyor installation: Installation generally carried out according to the following stages:

1) Install belt conveyor rack rack rack installation is started from scratch, and then install the sections sequentially intermediate frame, the final installation of the

tailstock. Before installing the rack, the first full length of the conveyor pulling the central line, due to the central line to keep the conveyor belt in a straight line is

An important prerequisite for normal operation, so when you install the rack sections, should be aligned to the center line, but also put on airs leveling the rack on the

central line of the promised error per meter captain of ± 0.1mm. But the length of the conveyor frame on the central error should not exceed 35mm. When all the single

Install and to identify the section can then be connected to each block.

2) Install the driver when the device is mounted drive unit, must pay attention to the belt conveyor belt conveyor drive shaft and the vertical center line of the drive roller

conveyor width and the center of the center line coincides with the axis of the shaft line reducer parallel. Also, all shafts and rollers

Should be leveling. Axis horizontal error, according to the width of the conveyor, agreed to within the range of 0.5-1.5mm. Driving means installed at the same time, the tail

wheel, etc. can be mounted tensioning device, the tensioning device of the axis of the drum, should the belt conveyor perpendicular to the center line.

3) mounted in a rack rollers, gear and tensioning device after installation, you can install the upper and lower idler roller frame, so that the belt has a slow change to the

curved arc, bending roll cage segment prop prop pitch as normal roller frame pitch 1/2 to 1/3. Idler installation, you should make it light and flexible rotation

4) belt conveyor belt in order to ensure the final pinpoint idlers and rollers are always in the center of online operation, installation rollers, racks and rollers when

Must meet the following requirements:

(A) all necessary roller line up parallel to each other and keep the horizontal level.
(2) all rollers arranged in rows parallel to each other.
(3) required linear frame supporting structure, and to keep the horizontal level. To this end, the drive roller and roller frame installed, should be the center of the conveyor

line and level for final alignment.
4) and then fixed on the basis of the rack or floor. After a fixed belt conveyors can be fitted to the loading and unloading devices.
5) Let hanged hanging conveyor belt, the first shop in the strip conveyor idlers load segment, the Wai hold after the drive roller, and then deposited in the heavy segment on

roller. Let hanging strips of use 0.5-1.5t hand winch. Connecting strip in tension, should roll tensioning device

Move cylinder limit position of the car and screw tensioning device To pull the gear shift direction; while picking up tight vertical move to the top of the drum to make the

device. In previous belt tension should be installed reducer and electric motor, inclined conveying confidential installed brakes. Belt Conveyor

After installation, the need for idling test machine.Airport conveyor

In the idling test machine, pay attention to whether the running belt deviation phenomenon, driven sector operating temperature, roller operation flow of the cleaning device and

the guide plate in contact with the belt surface rigor, etc., while make the necessary adjustments, the components are normal before they can

Performed with a load test machine running. If using spiral tensioning device, with load test machine, but also once again its tightness adjustment.



Second, the belt conveyor maintenance:



(A), starting and stopping the conveyor should generally be in the premise of no-load start. By installing several units in the conveyor belt should be used when you can lock

the starter to the control room through a certain order to start and stop. In addition, in order to prevent unexpected accidents, each conveyor

Machine should be set in place to start or stop buttons can be individually Renyiyitai repose. To prevent the belt for some reason are longitudinal tear, when the conveyor

length exceeds 30m, the length along the conveyor should distance intervals (eg 25-30m) to install a stop button

.




 (Two), in order to ensure reliable operation of belt conveyors, the most important is to detect and eliminate possible failures. Staff must always observe this manipulation of

the work of transport, such as abnormal should timely manner. Mechanical inspections and checks of workers should be any need to stay

Or components intended situation, it is very important. For example, a roller, does not seem very important, but a high-speed conveyor belt worn materials may soon put its shell

worn out, thrown a blade, the blade could gravely damage an expensive belt. Trained

Exercise or experienced workers working staff can discover imminent accident and take preventive measures. Belt conveyor belt conveyor in the whole capital in accounting for a

large proportion of proportionality. In order to reduce replacement and maintenance of conveyor expense, must face up on the manipulation of staff and maintenance

Staff for the operation and maintenance of conveyor knowledge training.
