Belt conveyor is a kind of continuous transportation equipment commonly used in mine, which has the advantages of strong transportation capacity, stable operation, simple structure, and so on. With the construction of large and super large mines, high-power, high capacity, intelligent, high-speed belt conveyor is more common. Now let's take a look.
Here is the content list:
l What is the tension requirement of a belt conveyor?
l What is the automatic tensioning device of the belt conveyor?
l What are the belts of the belt conveyor?
The belt conveyor keeps normal operation, and the tension applied to the belt should meet the requirements of sag, stability, and tension change. First of all, to meet the requirements of belt conveyor in power transmission and belt sag, the tension value of the equipment during start-up is about 1.3 ~ 1.5 times that during stable operation. Secondly, after the stable operation of the belt conveyor, the tension value of the belt will be significantly reduced and tend to be stable. Finally, the transport capacity of the belt conveyor changes at any time, and the tension value of the belt also changes. When the conveyor is empty, the tension of the belt is small, but when it is heavy, the tension increases.
The main equipment of belt conveyor includes electric winch, tension drum, hydraulic pump station, etc. the specific working principle is: when the belt tension of belt conveyor increases or decreases, the oil pressure in the oil cylinder will increase or decrease, and then the pressure sensor will send monitoring signals, and the hydraulic pressure system will respond according to the preset program according to the pressure change monitored by the sensor, Control the movement of piston rod to ensure the tension of conveyor belt; When the tension value of the belt conveyor is reduced to the minimum set value, the pressure value in the oil cylinder is reduced, the sensor sends out a signal, the hydraulic pump station automatically supplies hydraulic oil to the front of the oil cylinder, the piston rod retracts backward, and the belt is tensioned. The hydraulic automatic tension device has the characteristics of fast response, stable start, small belt tension fluctuation, and high reliability, which is widely used in belt conveyors.
First of all, there is a kind of belt conveyor belt called a heat-resistant conveyor belt. The heat-resistant conveyor belt is made of multi-layer rubber cotton canvas (polyester-cotton cloth) or polyester canvas covered with heat-resistant or heat-resistant rubber and bonded together by high-temperature vulcanization. It can transport hot coke, cement, slag, and other materials below 175 ℃. It is mainly used in metallurgy, construction, and other industries to transport sinter, coke, slag, etc Cement clinker, and other high-temperature materials. There is also a kind of cold-resistant conveyor belt. The cold-resistant conveyor belt uses cotton canvas, nylon canvas, or polyester canvas as the belt core. The covering rubber is a mixture of rubber and cis-1,4-polybutadiene rubber. It can be used at - 40 ℃ and has the characteristics of the high elasticity, impact resistance, and cold resistance.
Huzhou Longwei Import & Export Co., Ltd. has developed a variety of belt conveyors and conducted a lot of research, evaluation, and prediction before release to ensure the quality. This kind of belt conveyor is cost-effective. If you are also engaged in the belt conveyor business, you can consider using our products.
