Product Description

High Efficiency Industrial Helical B3sh B3hh B3dh Gearbox Gear Reducer Bucket Elevator Drive Gearbox
Description:
The HB Series is a high performance, general service control valve designed using Computational fluid Dynamics (CFD)for high control accuracy, optimized flow characteristics and extended service life. These control valves, with stainless steebodies, are equipped with a contoured plug design to withstand the rigorous nature of steam service and are compatiblewith many fluids and environments, Modern manufacturing techniques and modular construction allows these stainlesssteel valves to be extremely cost-elective in comparison to valves with bronze, cast iron or cast steel bodies.The standardconfiguration has an equal percentage flow characteristic with metal-to-metal seating, spring-loaded V-ring stempacking and pneumatic actuator. The HB Series is available with both pneumatic or electric actuation.
Features:
1. Generally accepted design of H.B Series Gear Units, transformable to industry-specific gear units according to customer's requirement.
2. Sound-absorbable structure, lager surface area and bigger fan; advanced grinding process of cylindrical and bevel gears, resulting in limited temperature rise, low noise, improved stability and larger transmission power.
3. Mounting mode: Foot-mounted, flange-mounted, swing base-mounted, torque-arm-mounted.
4. Input mode: motor connection flange or input shaft.
5. Output mode: solid shaft with parallel key, hollow shaft with parallel key, hollow shaft with shrink disk, hollow or solid shaft with involute splines, solid shaft with flange.
6. Obtaining larger ratio combined with R, K and S series.
