Safety operation regulations for belt conveyor
1, fixed conveyor should be required for the installation method to install on a fixed basis. Mobile conveyor wheels should be before the official run with triangular wooden wedge, or with a brake check. So that, when there are multiple parallel operation of conveyor, between machine and machine, between the wall and there should be one metre of the channel. 2, shall inspect all machinery before use of conveyor, belt buckle, and host device is normal, protective equipment are complete. Belt tension should be adjusted before starting to an appropriate extent. 3, the belt conveyor unloaded start. After normal operation, such as feed. Prohibit driving after feeding. 4, there are several conveyor-line runs from the discharge end, starting in the order. After all normal operations in order to feed. Belt deviation phenomena appears in the 5, run, stop adjustment shall reluctantly use to avoid edge wear and increase the load. 6, work environment and be sent material shall not be higher than 50 ° c and temperature lower than-10 degrees centigrade. 7, against pedestrian or riding on a conveyor belt. 8, parking must be stopped before feeding, and other uploaded material handling belts do before they can stop. 9, conveyor motor must be well insulated. Mobile conveyor cables don't pull and drag. Reliable earthing of motor. 10, is strictly prohibited to use hand to pull the belt when the belt slipping, so as to avoid accidents.
Misalignment fault belt line and the solutions
A mount of belt conveyer belt deviation is the most common fault. To address such failures key to note that the installation of dimensional precision and day-to-day maintenance. Running a number of reasons, be addressed according to different reasons for difference between: 1, adjusting the carrying idler group. 2, the installation of self-aligning idler group. 3, adjust the position and bend pulley driven drum. 4, tensioning adjustment. 5, bi-directional adjustment of belt conveyor belt running deviation than one-way adjustment of belt line deviation relative to many difficulties, specific adjustment should be adjusted in a certain direction, and then adjust the other direction.
Routine maintenance of belt conveyor
1, check all fasteners and verify that there are no loose. 2, cleaning the belt and make sure that the belt intact, damage should be replaced in a timely manner if a belt is found. 3, check the motor lubricating oil in the gear box and ensure that normal. 4, check of belt tension and adjust to the right.
