PROBLEM The Water Treatment Industry uses large slow paddle wheel flocculators to mix chemicals in the treatment process. These slow, high torque drives are subject to several overloads, which will break couplings, damage paddles or shear shafts. Just getting the large paddles started in […]
Read MorePROBLEMA large wastewater treatment facility has several process tanks, which contain large, slow moving, mixing arms. The nature of the design results in some occasional large overloads. The original design included shear bolts. The operators quickly figured out that a heavy bolt reduced the […]
Read MorePROBLEM A power plant had several large fans in their system. Unfortunately, the idle fans pin-wheeled in the reverse direction due to ambient airflow, even when the dampers were closed. When the idle fans were started, a significant chock load resulted in rolled keyways […]
Read MorePROBLEM Power generating stations are particularly sensitive about outages. Being able to properly schedule equipment maintenance is the key to successful operation. SOLUTION A public utility installed counters and hour meters on every piece of rotating equipment. They were then able to track every […]
Read MorePROBLEM A processing plant runs a large inclined conveyor to feed the entire operation. A large holdback clutch prohibits the loaded belt from reversing which would be disastrous. Because of the critical nature of this installation, they have two units on the head shaft, […]
Read MorePROBLEM After 25 years of operation, the hydraulic drum brakes on the roll stands had become a high maintenance item. Additionally, it had become increasingly difficult to maintain consistent tension control. SOLUTION A careful review of the application was necessary to determine the required […]
Read MorePROBLEM A large paper mill operates a 500 HP drive running a 15′ diameter steam roll at 800 RPM. Due to the layout of the process, a significant shaft offset existed necessitating the use of a universal shaft. During operation, they noticed a vibration. […]
Read MorePROBLEM Our customer uses a universal shaft assembly to drive his printing press rolls. The need to move the roll creates some high misalignment angles dictating a universal assembly. They found some objectionable vibration during operation. SOLUTION Upon review of their new operating requirements, […]
Read MorePROBLEM Our customer manufacturers corrugated boxes. One of their roll drives involved a universal-joint assembly to accommodate a rather severe angle (20°). Unfortunately, the shaft failed on a regular basis. They needed to eliminate this costly maintenance headache. SOLUTION We reviewed the application. The […]
Read MorePROBLEM A printer found that he was replacing a pin and block style universal joint on his embosser weekly. Heavier universal joints only seemed to result in gear box bearing failures. SOLUTION A careful review of the installation revealed that the misalignment involved compound […]
