One, what is a belt conveyer
Before we discuss the application scope and maintenance techniques of belt conveyor, we should first understand what the belt conveyor is. The belt conveyor is defined as follows: belt conveyor is also called belt conveyor (also called belt conveyor). It is a kind of continuous conveyer. The transport characteristic of belt conveyer is to form the continuous material flow between the loading point and the loading point, and complete the transportation from the loading point to the unloading point by the whole movement of the continuous material flow. The conveyer belt moves according to the principle of friction transmission, which is suitable for the powder, granular and small block of low grinding and cut material and bag material which is easy to take out of the packing density less than 1.67/ tons / cubic meter.
Two, the application range of belt conveyer
Belt conveyor is a kind of friction driven continuous machinery to transport materials. It can be used to transfer material to a certain conveying line, from the initial feeding point to the final unloading point to form a material delivery process. It can not only transport the broken materials, but also carry out the transportation of the articles. In addition to the pure material delivery, it can also coordinate with the requirements of the technological process in the production process of various industrial enterprises to form a rhythmic flow operation line. Therefore, the belt conveyor of the running water bus is also widely used in all kinds of modern industrial enterprises. Belt conveyors are widely used in underground roadway, mine ground transportation system, open pit and mineral processing plant. The conveyor can be transported horizontally, vertically and vertically, and can also form a space transmission line. The transmission lines are generally fixed and are very convenient to use.
Three, the maintenance skill of belt conveyer
According to the experience of many years, the maintenance technique of belt conveyer is mainly used in two aspects, one is the starting and stopping of the belt conveyer, and the two is to find and eliminate the fault of the belt conveyer in time. Detailed maintenance techniques are as follows:
(1) start and stop; conveyor generally should start under no load condition. In order to install several belt conveyors sequentially, a lockable starting device should be adopted so as to start and stop in a certain order through the centralized control room. In addition, in order to prevent sudden accidents, each conveyor should also set up a local start or stop button, and it can stop any single stop. In order to prevent the conveyor belt from being torn longitudinally for some reason, when the length of the conveyor is more than 30m, a stop button should be installed at a certain distance (such as 25 - 30m) along the length of the conveyor.
(two) finding and troubleshooting. In order to ensure the reliable operation of the belt conveyor, the most important thing is to detect and eliminate possible faults in time. For this reason, the operator must observe the working condition of the transporter at any time, and if abnormal is found, it should be dealt with in time. It is very important for mechanical workers to inspect and inspect any situations or components that need attention regularly. A roller, for example, does not seem to be very important, but the high speed conveyer belt that conveyed the worn material may quickly wear its shell through and appear a knife edge, which can seriously damage an expensive conveyor belt. Trained workers or experienced staff can detect accidents in time and prevent them from happening. The conveyor belt of the belt conveyor occupies a large proportion in the cost of the conveyor. In order to reduce the cost of replacement and repair of conveyor belts, attention must be paid to training operators and maintenance personnel for the operation and maintenance of conveyor belts.
