Damper braking system but also with mobile high-pressure pump rotor from the top to meet pumping tile inspection, the establishment of film and other processes required. The guide bearing mounted within the frame tank, bearing plate support for the wedge, block tile structure, wattage 12.
Tile material is tin-bearing alloy, installation, scraping, so at any speed can be established between tile uniform film with the shaft. Tile gap first with a pair of special tools to adjust, and then fixed with a wedge plate fine tuning. The lead tank 12 within a single pipe string Unicom cooler water cooling. Thrust and the guide are used comb seal.
Unit cranking required torque, using a dedicated electrical device to the rotor and stator windings through direct current method of generating an electromagnetic torque. When the rotor windings and stator phase windings simultaneously either through direct current with time, the magnetic force generated between the stator and rotor interaction, that same polarity repel different polarity attract the rotor to rotate.
Known generator explosion distribution box manufacturers frequency 50H :, rated speed is n, the rotor while the power once, geometric angle of the rotor is turned 0.04n. According to installation needs, but also to control the rotor jog or continuous rotation. Barring starting torque is approximately: water-cooled screw unit unit rotating part weight thrust bearing fulcrum fire radius KO. 07. Electric Turning to replace the traditional mechanical disk drive, improve the labor intensity.
Generator copper loss drying, short circuit test, boost test are used electric winch provides DC power. Installation schedule generator stator occupied for a long period in the unit is installed in a straight line, the rotor assembly of large projects, assembly time is longer.
Rotor assembly period were 98d, sod, 86d, 53d. Stator and rotor lifting schedule is one of controlled unit installation schedule. In accordance with the requirements of the overall progress, when a machine previous generation, two base station machines should be poured next to the generator layer, and should be substantially cleaned. In fact, the image of the 24th and engineering installation and acceptance volute complete, since the construction of the second phase of silicon postponed, the objective of the installation period has been determined for each unit. But in a relatively short period of time in installation, commissioning planned for each machine on the total schedule requirements are on schedule.
