Liquid seal has broken or is close to breaking due to:(1)Filling too fast at start;(2) Too little seal liquid.2. Closed valve in light phase outlet.3. Gravity disc too large.4. Throughput too high.5. Seal ring under gravity disc missing or damaged.6. Changed separation temperature resulting in changed density ratio.7. For bowl with paring disc, back pressure too high.

四、請將下列對話翻繹成中文(20%)Dialogue 1 Application for stopping the main engineB: Excuse me, sir. May I stop the main engine right now?A: What's the matter?B: A fire occurred in the scavenge air box.

How much can it produce?B: Only 20 tons. I think it's due to the scale and air leakage.Dialogue 3 Parallel operationA: Please show me where the main switchboard is.B: This way, please.A: First of all, please tell me the functions of meters and switches.B: All right.A: Could you show me the parallel operation?B: Regulate the voltage and frequency first. Then watch the synchroscope. While the pointer is running slowly clockwise, turn on the breaker when the pointer is at 11.A: All right.B: Anything else?A: No, thank you.
