Product Description
The belt conveyor self-controlled hydraulic tensioning device, developed based on the characteristics of our country's belt conveyors and absorbing advanced technology from industrially developed countries worldwide, takes into account the varying tension requirements of belt conveyors during startup and normal operation. It is the result of rigorous analysis and research of the belt tension model, coupled with extensive experimentation. This device boasts excellent dynamic performance, high reliability, compact structure, minimal installation space, and simple operation, making it the ideal equipment for belt conveyor tensioning.
This unit is widely used in the conveying systems for bulk materials in industries such as coal, power, metallurgy, ports, and construction materials, and is suitable for both fixed belt conveyors and telescopic belt conveyors.
Product Features
Wide adjustment range
This device is designed based on the characteristics of belt conveyors, allowing the traction and normal operating traction to be adjusted arbitrarily according to the tension requirements of the belt conveyor, fully meeting the requirement for the starting force to be 1.3-1.5 times that of normal operation. After the electro-hydraulic system is adjusted, the tensioning device operates automatically according to the predetermined program, ensuring the conveyor belt runs in an ideal condition. Therefore, belt conveyors equipped with this tensioning device can reduce the thickness of the conveyor belt.
High-speed dynamic response capability
This device responds quickly and dynamically. During startup, the belt conveyor is in an unstable state. At this point, the tensioning device, through the rapid extension and contraction of the hydraulic cylinder, promptly compensates for the elastic oscillation of the conveyor belt, effectively achieving dynamic tensioning of the belt conveyor. This reduces the impact dynamic load during startup, ensuring reliable startup, and also effectively prevents over-tensioning of the conveyor belt by the tensioning device.
Comprehensive protection features
The system features timely ribbon detection signals upon belt breakage, controlling the automatic shutdown of belt conveyors and automatically increasing tension during belt slip, along with protection capabilities. It also includes multiple functions such as hydraulic system protection and electrical control system safety protection.
Achieve unattended operation
This unit can be connected to the belt conveyor's integrated control device, "PLC," allowing for long-distance control of the automatic tensioning of the belt conveyor, ensuring reliable operation of the conveyor.
Energy-saving and consumption reduction
Under constant main parameters of the conveyor, using a hydraulic automatic tensioning device reduces the belt strength grade and the installed power of the conveyor, thereby reducing initial equipment investment, saving electricity, and cutting operation costs, offering significant economic benefits.
Compact structure, small installation space.
