In this scenario, SCADA workstations and the number of printers can be expanded, but also may need to use network printers, and can be expanded dispatch operation and management functions.

As the sleeve 2 is fixed axial position, resulting in putting 3 to move to achieve the change in amplifier (Figure 2) The purpose of the pressure spring force. If the operator hand wheel 6, the hand wheel will be directly contributing to the sleeve 2 moves back and forth leaving the putt 3. This time due to the role of self-locking worm gear, worm gear 4 to 5 and ratchet teeth between the slip face. Figure 2 Analysis and processing amplifier 3 from the synchronization of the structure theory to analyze, synchronizer activities appear insensitive, common causes and phenomena in Table 1. Biao 1 synchronous device Huodong insensitive to the phenomenon of serial Yuanyin phenomenon causes and run the unit in the processing Youyu 四号 overhauled to be connected operation, to shut down handle synchronization malfunctions, that is interrupted by Lian Yun records, but does not handle Tongbu malfunctions, the unit operation is very safe. To this end, the synchronizer in the unit operation to check the processing of projects, one by one examination to exclude. 3.1 Check the back wheel motor connector is not skewed,
mbt shoes ireland, and no loss. Exclude the possibility of failure caused by synchronizer. 3.2 from the synchronizer failure phenomenon,
tory burch outlet, the synchronizer can reduce the load, indicating the synchronizer motor can rotate, Worm is not killed; motor rotates, the worm has not heard a different steady tone, indicating the worm gear bearing is not broken, But the driving force meets the drive motor speed converter is a doubt, the replacement motor. The results of ever, so we can rule out the motor is faulty. 3.3 hand-wheel drive mechanism is a jam. For reducing the transmission parts to the relative increase friction between the motor driving force to consider in preparation for the hand of the synchronizer friction wheel drive mechanism for cleaning up the contact surface. First, run the duty to inform the operating parameters to stabilize, and then quickly remove the hand wheel drive mechanism to check their mutual contact surfaces, and found that contact surface of the black marks are,
p90x workout schedule, there is a small hand touching particles, coated turbine oil clean up after a little , re-installed hand-wheel drive mechanism. Duty to inform commissioning run, the results of remote electric operation synchronizer subtraction load free, but very sensitive to transmission synchronizers. 4 Conclusion ago, never doubted the pass-through wheel friction drive mechanism will affect the normal operation of the synchronizer, as the case in hand is normal, especially when the jam slightly,
love bracelet cartier, it is difficult to find. Four machine synchronizer failure to handle, run and then there have been no exception; September 23, 2001, Guixi Power Plant Unit 2 in the 80 ~ 85MW or more loads, also synchronize remote electric operation can only reduce load can not increase the load of the phenomenon, using the method of handling 四号 machine processing, the effect is very obvious, the 2nd unit treated the work of running the Synchronizer has been normal.
