Type 1 U1 Split Taper Bushing

Fan Hub Installation

5–Position the bushing-hub assembly over the Geareducer fan shaft. Carefully align the bushing bore keyway with the previously installed shaft key—or if using a Type 2 split taper bushing, align the shared hub/bushing key with the fan shaft keyway. Lower the assembly onto the shaft. The assembly must slide onto the output shaft enough to ensure the shaft key runs the entire length of the bushing bore. It may be necessary to slightly wedge open the split taper bushing for easier engagement of the fan shaft into the bush- ing bore. This can be accomplished by driving a wedge into the bushing flange split.

6–Using a torque wrench, tighten the stainless steel cap screws sequentially until each is tightened to 140 ft·lbƒ (190 N·m). When the cap screw torque is at or near 140 ft·lbƒ (190 N·m), make at least two more sequential rounds to assure all cap screws are to the required torque value.

HP700 specifications

SPX Cooling Technologies HP700 is a state-of-the-art cooling tower designed to meet the demanding needs of modern industrial and commercial applications. With its robust construction and innovative design, the HP700 offers reliable performance while minimizing energy consumption and operational costs.

One of the main features of the HP700 is its high-efficiency fan design, which significantly enhances air flow and cooling capacity. The use of advanced aerodynamics in the fan blade design reduces energy consumption while maintaining optimal cooling performance. Additionally, the variable frequency drive (VFD) technology allows for adjustable fan speeds, ensuring that the cooling tower can respond effectively to fluctuating thermal loads.

The HP700 also boasts a unique, patented fill design that maximizes water distribution and contact time. This enhanced fill enhances heat transfer efficiency, allowing for more effective cooling in a compact footprint. The fill material is constructed from durable, corrosion-resistant materials, ensuring longevity and reduced maintenance needs.

Energy efficiency is a priority for the HP700, which incorporates the latest technologies in terms of heat exchange and water management. The design includes advanced drift eliminators that reduce water loss, while specially designed nozzles ensure optimal water distribution across the fill. This innovative approach not only preserves water resources but also enhances overall system performance.

In terms of construction, the HP700 is built with high-strength materials, including fiberglass-reinforced plastic and stainless steel. These materials offer superior resistance to corrosion and wear, making the HP700 suitable for a variety of environments, including those with harsh chemical exposure or varying weather conditions.

Another noteworthy characteristic of the HP700 is its modular design, which allows for easy installation and scalability. This feature enables facilities to expand their cooling capabilities as their requirements grow, ensuring long-term operational flexibility. Additionally, SPX Cooling Technologies provides comprehensive support services, including installation assistance and ongoing maintenance, further enhancing the value of the HP700.

In summary, the SPX Cooling Technologies HP700 is a highly efficient, durable, and flexible cooling solution that stands out in the competitive market. Its cutting-edge features, including advanced fan technology, optimized fill design, and energy-efficient operation, make it an excellent choice for a wide range of industrial and commercial cooling applications. With its commitment to quality and performance, SPX Cooling Technologies continues to lead the way in innovative cooling solutions.
