The bucket elevator, as the "backbone" of vertical bulk material transportation, plays a crucial role in industries such as mining, cement, grain processing, and chemical engineering.
However, its operation often encounters challenges such as significant startup shocks, frequent overload shutdowns, rapid wear of transmission components, and poor power matching. These issues not only affect production efficiency but also lead to high maintenance costs.
How can we break the deadlock? A high-performance torque-limiting hydraulic coupling is precisely the key to enhancing equipment reliability and efficiency.
I. Hydraulic Coupler: The "Guardian" Ensuring Efficient and Stable Operation of Bucket Elevators
The limited-torque hydraulic coupling, with its unique hydrodynamic transmission principle, establishes a "flexible bridge" between the bucket elevator and the drive motor. Its core value lies in:
Mitigating Startup Impact: Achieve near-"no-load" motor startup, significantly reducing current and easing the burden on the power grid while protecting motor lifespan. The smooth startup process prevents mechanical shocks to critical components such as the bucket elevator chain, buckets, and head and tail bearings.
Intelligent Overload Protection: When the bucket elevator encounters sudden blockages or severe overloads, the coupling unit automatically "slips," limiting torque transmission and effectively preventing catastrophic failures such as motor burnout or reducer shaft breakage, thereby providing intrinsic safety protection for the system.
Isolate harmful vibrations: The liquid medium effectively attenuates and isolates torsional vibrations between the motor and the driven machine, reducing transmission system noise and minimizing issues such as bolt loosening and bearing failures caused by vibration. This significantly enhances the overall operational stability of the equipment.
Optimized Power Matching: The flexible transmission characteristics enable superior power matching between the motor and the load, particularly ensuring efficient operation of the equipment under conditions with loaded starts and significant load fluctuations.
II. YOX750 Limited-Torque Hydraulic Coupler: Specifically Designed for Bucket Elevator Operating Conditions
Zhongxing Hydraulic Transmission has been deeply rooted in the industry for many years. Its star product, the YOX750 torque-limiting hydraulic coupling, has become the ideal choice for upgrading bucket elevator drives, thanks to its outstanding performance parameters and reliable quality.
1. Powerful performance with extensive coverage:
When the input speed reaches 1000 rpm, the power transmission range is between 170 and 330 kW.
When the input speed reaches 1500 rpm, the power transmission range can be as high as 380–760 kW.
Meets diverse power requirements for bucket elevators ranging from small to large sizes.
2. Precise torque limitation for safety and reliability
Starting overload factor: 1.5–1.8
Braking Overload Coefficient: 2–2.5
A scientifically designed overload factor ensures sufficient starting torque to guarantee smooth equipment operation, while precisely limiting the maximum transmitted torque, thereby providing optimal protection for the system.
3. High efficiency, energy-saving, and cost-effective with durable performance:
Rated efficiency reaches up to 96%, with minimal transmission losses, effectively reducing operational energy consumption.
Zhongxing Hydraulic Transmission's rigorous production processes and quality control system ensure that every YOX750 unit delivers stable quality and superior performance, guaranteeing long-term, trouble-free operation of the equipment.
