Electrolytic starter (LRS) for high power slipring motors ...
The starting torque is extremely high. For example, for a 110 kW motor with a ratio starting torque / nominal torque of 2.4, this torque is applied by the motor shaft to the driven machine which can make either an early ageing of the mechanical coupling (transmission shaft or transmission belt) or even the break of the driven machine.
Ball Valve - an overview | ScienceDirect Topics
Seals are usually resilient and can provide drop tight shut off. Ball valves are commonly used in small diameters (up to DN 300) although at least one manufacturer can make ball valves up to DN 1200. Ball valves are manufactured in one-piece, top entry, two-piece (Fig. 18.6) and three-piece bodies. A top entry body allows access to the ball and ...
