With the improvement of the production capacity of coal mine in China, the model of scraper conveyor is getting bigger and bigger, and higher requirements are put forward for the spare parts of scraper. The traditional brake disc type tight chain device has been unable to meet the requirements of production, scraper conveyor hydraulic motor tight chain system has become the choice of more large scraper conveyor.
The hydraulic motor tight chain system has the following advantages:
(1) The braking mode is reasonable and reliable. In the large scraper conveyor, the excessive torque can not be braking through the brake disc, and the hydraulic motor tight chain system internal braking function braking, the way is more reasonable, more reliable.
(2) Low fastening speed is conducive to control. The hydraulic motor tightens the chain, the motor speed is 100 RPM, after the reducer, the drive sprocket speed is lower, the chain speed is lower, more conducive to control.
(3) Simple operation, more conducive to control. Compared with the brake disc chain tightening device, the scraper conveyor hydraulic motor chain tightening system only needs to pull the operation handle or press the operation button, and the hydraulic system can complete the chain tightening.
(4) High safety factor. Hydraulic motor chain fastener has the advantage of hydraulic system, compared with the brake disc chain fastener of mechanical brake, overload unloading and transmission torque is more stable, high safety.
Scraper conveyer hydraulic motor tight chain system progress day by day, together with the coal mine fully mechanized working face automation degree more and more high, will become the future coal machine configuration mainstream. Henan Shuanzhi production of various types of hydraulic chain, brake disc chain, about more scraper accessories, you are welcome to telephone consultation.
