Based on the daily running of paper machine the inherent trouble shut down in production and its regular pattern were analyzed in order to finish the maintenance,repair and rebuilding of the equipment in the shut down time,therefore to reduce or eliminate the frequent shut down of the paper machine.

Improvement of Shutdown Protection Circuit for 125MW Power Generating unit;

By means of the analysis of the thermal stresses of the rotator during startup and shutdown for a 600MW steam turbo generator unit,we can know that its surface of the shaft is suffered the stress properties.

According to analysis for the test data of two steam turbines,it is indicated that much attention should be paid not only duriug start-up,but also shutdown.

The reason analysis of hydrogenerator unit self-rotation after stopping air brake quitting;

voltage is the critical voltage for stalling,and the current impact can reach five to ten multiples of the normal when the air-conditioner starts and will come back within 0.

In order to study the start-up and shut-down characteristics of R410A split air-conditioners under cooling mode, the refrigerant distribution in the system as well as temperatures and pressures at the suction and discharge point were measured during first 30 min at start-up and shut-down, respectively.
