Operation and maintenance and installation of belt conveyor.
First, start and stop conveyor should normally be started in no-load conditions. There are several units in the sequential installation of belt conveyors should be used to lock the starter to the control room through the set of starting and stopping a certain order. In addition, to prevent incidents, each conveyor 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 were longitudinal tear, when the conveyor is longer than 30m, the length along the conveyor should be a certain distance away (such as 25-30m) to install a stop button.Second, the conveyor belt in order to ensure the maintenance of reliable operation, the most important is to detect and eliminate possible failure. To do this the operator must always observe the work of transport, such as unusual should be a timely manner. Workers should regularly inspect machinery and check for any situation or parts need to pay attention, it is very important. For example, a roller, do not seem very important, but high-speed conveyor belt worn materials may soon wear out it's shell, the emergence of a blade, the blade could seriously damage an expensive belt. Workers trained or experienced staff can discover about the incident and take preventive measures. Conveyor belt conveyor costs in the entire account for a large proportion. In order to reduce the cost of replacement and maintenance of conveyor belt, we must attach importance to the operators and maintenance personnel for the operation and maintenance of the conveyor belt of knowledge training. Table l-40 lists the occurrence of a large number of operational problems related to belt causes and approach. Cause of belt failure and EliminationThird, the installation of conveyor belt installation generally based on the following several stages.1) Install the belt rack rack rack installation is started from scratch and then install the sections between sequential frames, the final installation of tailstock. Before installing the rack, the first full-length on the conveyor Pull the centerline, the centerline due to maintain the conveyor belt in a straight line is an important condition for normal operation, so when you install the rack sections should be Align the center line, but also to put on airs leveling the rack on the center line of the permissible error, the captain of each meter is ± 0.1mm. However, full-length on the conveyor rack center error should not exceed 35mm. When all the single install and identify the following may be the single link.2) Install the drive when you install the drive, you must pay attention to the conveyor belt's centerline and the vertical shaft, so that the width of the central drive roller and the conveyor centerline coincides with the axis of gear line parallel to the drive shaft. At the same time, all the axis and the roller should be leveling. Axis horizontal error, according to the width of conveyor, allowing 0.5-1.5mm range. While installing the drive, you can install the rear wheel and other tensioning device, tensioning device of the drum axis, the vertical center line of belt conveyors should be.3) Install the rack roller, transmission device and tensioning device installed, you can install the upper and lower idler roller frame, the conveyor belt with a slow change to a curved, bent roll cage care section turn spacing normal care roller frame spacing of 1 / 2 to 1 / 3. Roller installed, should it turn light and flexible.4) Finally, identify the conveyor belt to ensure always roller and the roller center line to run, install roller, roller frame, and whenMust meet the following requirements:(1) All rollers must be arranged in rows parallel to each other, and keep the horizontal level.(2) All of the rollers arranged in rows parallel to each other.(3) frame the supporting structure must be linear, and maintain the horizontal level. To this end, the drive roller and roller frame after installation, should the center line and horizontal conveyor for final alignment.4) and then fixed on the basis of the rack or on the floor. After the fixed belt conveyor can be fitted to the loading and unloading devices.5) hanging set hanging conveyor belt set when the conveyor belt first paragraph of Article shop in the empty roller, the roller drive around after the hold, and then deposited in the heavy segment on the roller. Set can be used with the article linked to 0.5-1.5t the hand winch. Article in connection with tension when the tensioning device of the roller should be moved to extreme positions on the car and spiral tensioning device to the transmission direction of pull; and vertical installation make the rollers move to pick up close to the top . Conveyor belt before the tensioner should be installed reducer and motor, tilt conveyor installed brake confidential. Belt installed, the need for idling test machine.In the idling test machine, we should pay attention to whether the deviation of the running conveyor belt phenomenon, driven part of the operating temperature, roller running in the activities, cleaning device and the guide plate and the belt tight degree of surface contact, while make the necessary adjustments, all components are normal after the operation can be with a load test machine. If using screw-type tensioning device, the test machine with a load operation, but also its tightness to make another adjustment.
