Product Description

The belt conveyor automatic hydraulic tensioning device, designed with the characteristics of our country's belt conveyors, incorporates advanced technology from industrially developed nations worldwide. Considering the varying tension requirements of belt conveyors during start-up and normal operation, it is developed through rational analysis of the belt tension model and extensive experiments. This device boasts excellent dynamic performance, high reliability, a compact structure, minimal installation space, and easy operation, making it an ideal equipment for belt conveyor tensioning.

This device is widely used in the belt conveyor systems for transporting scattered construction materials in industries such as coal, electricity, metallurgy, ports, and building materials, and is suitable for both fixed and telescopic belt conveyors.

Product Features

Wide adjustment range

This device is designed based on the characteristics of belt conveyors, allowing the pulling force and normal operating force to be adjusted arbitrarily according to the tension requirements of the belt conveyor, fully meeting the requirement of 1.3-1.5 times the starting force for normal operation. After the electro-hydraulic system is adjusted, the tensioning device operates automatically according to the pre-set program, ensuring the conveyor belt runs in an ideal state. Therefore, belt conveyors equipped with this tensioning device can reduce the thickness of the conveyor belt.

High-speed dynamic response capability

This device features rapid dynamic response. During startup, the belt conveyor is in an unstable state. At this point, the tensioning device promptly compensates for the elastic oscillations of the conveyor belt through the rapid extension and contraction of the hydraulic cylinder, effectively achieving dynamic tensioning of the belt conveyor. This reduces the impact dynamic load during startup, ensuring reliable operation, 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 to control the automatic shutdown of the belt conveyor and automatically increase the tension during belt slip, offering protection capabilities. It also includes multiple functions such as hydraulic system protection and electrical control system safety protection.

Achieve unattended operation

This device can be connected to the belt conveyor's centralized control unit, the "PLC," allowing for remote control of the automatic tensioning of the belt conveyor, ensuring reliable operation of the conveyor.

Energy-saving, consumption reduction

Under fixed 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 operational costs, offering significant economic benefits.

Compact structure, small installation space.
