Our meticulous production process for the drum is an intricate and highly precise operation that ensures exceptional quality and durability. At the outset, the drum is crafted directly from large, seamless steel pipes, which serve as the essential structural elements, providing unparalleled integrity. To attain the precise dimensions required, we leverage a cutting-edge flame cutting machine. This advanced device enables precision cutting, ensuring each drum component is sculpted to exact specifications.
In the realm of welding, we harness the power of a professional drum welding machine to join the inner discs of the drum. This specialized apparatus guarantees robust and dependable welds, significantly reducing the risk of structural weaknesses. For welding the drum shaft sleeves and discs, we employ a positioner. This invaluable tool allows us to achieve impeccable welding angles, resulting in seamless and enduring connections.
Subsequent to welding, a large lathe is utilized to machine the outer cylinder of the drum. This critical step ensures uniform wall thickness, which is vital for optimal drum performance. Additionally, it minimizes radial runout, promoting smooth and stable rotation. In the shaft processing phase, we meticulously select No. 45 round steel and shaft sleeves. This careful selection ensures shaft concentricity, mitigating eccentric forces that could otherwise cause vibrations and premature wear. By reducing these forces, the drum rotates with enhanced stability, thereby extending its lifespan and boosting operational efficiency.
We place paramount importance on the installation of bearings. We adopt high-quality bearings and bearing housings, complemented by bearing inner diameter enlargers. For installing the bearings, we employ a gentle heating method. By softly heating the bearings, they can be effortlessly positioned without resorting to forceful knocking, thereby preserving their integrity and functionality.
Moreover, based on operating conditions, we conduct specific treatments. When the resultant force borne by the drum exceeds 80 KN, stress relief treatment is essential to avert any potential structural damage. If the belt speed surpasses 2.5 m/s, static balance detection is imperative to ensure even, vibration-free drum rotation.
Regarding the production of various standard pulleys, our scope is impressively extensive. Diameters range from Φ114mm to Φ2400mm, while lengths extend from 260mm to 3400mm. This expansive range enables us to meet diverse industrial demands, from small-scale machinery to large industrial conveyor systems. Each pulley is crafted with the same precision and care as our drums, guaranteeing reliable performance across a wide spectrum of applications.
