如果在無流動期間,安全閥排氣口有水排出,則原因可能是, ( 1 )第一止回閥受到污染,或( 2 )由於上游壓力波動造成裝置的進口壓力下降太大。The simulation shows that the valve throttle area should be little as possible but must be more than 40 % of pipe section area ; when the total length of pipe is same, and the flow quantity is enough, pipe before primary valve should be thin and long, and the pipe after primary valve should be thick and short, the upriver and downriver small pressure fluctuation will badly lead to waterdrammer pressure rising, and spending more time in establishing pressure and flow quantity
模擬表明,閥門過流面積在滿足大於管道截面積40 %的條件下應盡可能小;在管道總長一定並滿足流量要求的條件下,主閥前應採取長而細的管道,閥后則應採用短而粗的管道;上下游微小的壓力波動都會嚴重增大開關閥門引起的水擊,並使壓力、流量的建立需要更長的時間。In fabricated valves, leakage of corrosive medium due to neglected maintenance on the packing, or line pressure surges causes corrosion and failure of most carbon steel or cast iron components
鍛鋼焊接裝配閥門,常會由於忽視了填料的維護而導致腐蝕介質的泄漏,或管路壓力波動導致腐蝕和大部分碳鋼或鑄鐵部件損壞。First, the dynamic characteristics of pipe is simulated, the influence to waterhammer which is brought by the flow area of the valve, response time, the length of the pipe before and after the valve, the hydraulic pressure fluctuating in the trunk, and the high frequency pressure fluctuating in combustion chamber is analysed
首先對管道動態特性進行了模擬,分析了閥門過流面積、閥門作動時間、閥門前後管道的長度、貯箱壓力波動以及燃燒室壓力高頻振蕩等對管道動態特性的影響。De - noisding by soft - thresholding is a new signal detection method in wavelet analysis
摘要採用浮動閥值分離噪聲是小波分析中一個新的信號檢測方法。Believes that gas pressure accumulator can absorb waterhammer pressure effectively, but it needs more time to achieve stable state. the consume - energy accumulator can not absorb one of opening valve effectively, but it can achieve stable state quickly. combination of the two style accumulators will be a nice choice
認為氣壓式蓄能器能有效地吸收水擊波動,只是達到穩定狀態需要的時間更長;耗能蓄能器對吸收開閥水擊的作用不佳,但穩定速度更快,將這兩種蓄能器的優點結合起來會是一個不錯的選擇。( 6 ) scientifically understanding the influence of crude nitrogen regulating valve fluctuation on the top of crude nitrogen i tower to oxygen content and purity of nitrogen fraction, so as to attain the goal of adjusting oxygenerator operation according to the above mentioned law. it has the significant guidance to regulate the operation of large - scale oxygenerator and worth being popularized
