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 centerline, because the centerline to keep the conveyor belt in a straight line is
Important condition for the normal operation, so the installation of the rack sections, must be aligned with the center line, but also airs leveling rack to the center line of
the allowable error, the captain of per meter ± 0.1mm. However, the full length of the conveyor error of the center of the rack must not exceed 35mm. When all the single
Install and to identify the section can then be connected to each block. industrial belt conveyor
2) Install drive unit mounted drives, you must pay attention to the belt conveyor belt conveyor drive shaft and perpendicular to the centerline, the width of the drive roller
conveyor centerline central and coincides with the axis of the shaft line reducer parallel. Also, all shafts and rollers
Should be leveling. The axis horizontal error, according to the width of the conveyor allowed within the range of 0.5-1.5mm of 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 be perpendicular to the centerline of the belt conveyor.
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
Fast. Pharmaceutical metal detector
4) belt conveyor belt in order to ensure the final pinpoint idlers and rollers are always in the center line of the operation, installation rollers, racks and rollers when
Must meet the following requirements:
(1) All rollers must line up parallel to each other and keep the horizontal level.
(2) all rollers arranged in rows parallel to each other.
(3) have a linear frame supporting structure, and to keep the horizontal level. To this end, the drive roller and roller frame after installation, should the centerline and the
horizontal conveyor 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 motor, tilt conveyor confidential installed brakes. Belt Conveyor
After installation, the need for idling test machine.
In the idling test machine, pay attention to whether the running belt deviation phenomenon, driven part of the operating temperature, roller during operation activities,
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 a 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 start in an unloaded condition. Should be used sequentially install several units belt conveyor can be blocked for the
starting device, control room in order to start and stop a certain order. In addition, in order to prevent unexpected accidents, each conveyor
Machine should be set in place to start or stop buttons can be individually stopped Renyiyitai. In order to prevent the conveyor belt for some reason is longitudinal tear, when
the conveyor is longer than 30m, the length along the conveyor, should be spaced a certain distance 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. This operation must always observe the work of
transport, such as abnormal should timely manner. Mechanical workers should regularly check for any required inspections and note
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, the emergence of a blade, the blade could seriously damage an expensive belt. Trained
Trained workers or experienced staff to detect impending accident and take preventive measures. Conveyor belt conveyor belt conveyor costs account for a large proportion. In
order to reduce the cost of replacement and repair belt, must pay attention to the operating and maintenance
Personnel in the operation and maintenance of conveyor knowledge training.
