At about 3 . 20 pm yesterday ( august 1 ) , a 44 - year - old man working for tate cairn tunnel discovered odd smell emitting from black plastic bags placed on a piece of grassland near the tunnel s ventilation pump room on lok wah street , tsz wan shan . a report was subsequently made to the police . police officers responding to the report located parts of a dismembered body contained in four black plastic bags 昨日(八月一日)下午約三時二十分,一名四十四歲在大老山隧道工作的男子于慈云山樂華街大老山隧道變壓站旁的草地發現一些傳出惡臭的黑色膠袋,他其后向警方報案。

Then it presents the control scheme . the whole control system composes of supplying water subsystem , purifying water subsystem , life sewage water subsystem , disposing waste water subsystem and rainwater pump room subsystem . every subsystem is a suit of absolute plc control system 整個控制系統由鍋爐補給水系統、凈水站系統、生活污水系統、工業廢水系統和雨水泵房系統五個子系統組成,每個子系統都是一套獨立的plc控制系統,各個子系統的控制程序均采用modicon公司的concept2 . 5編程軟件編制。

Cannula compensator is comprised of body tube , compensation tube , flange and gadket . the product is applied in the drainage engeineer , providing great convenience to the detachment and installation of water tower and water meter of pump room . and it plays a role to resolve the compensation issues caused by temperature difference for long pipeline . sgd , , axial displacement . , , , , , 套管式伸縮器是由體管伸縮管壓蘭密封圈構成的,此產品用于給排水工程,它為城鎮自來水塔泵房水表及閥門安裝拆換提供了極大的方便,以及對長距離管道用溫差引起的伸縮問題,起到了良好的填補作用。

So the pipe system sends out noise because of resonance . especially the frequency 250hz of pulsating water is in close proximity to natural frequency of pipe , so the 250hz is a dangerous frequency to the pipe system . there is another reason why the noise is reached to 110db ( a ) in pump room that the noise is magnified by the cistern because of the resonance of cistern 特別是激勵頻率為250hz的頻率分量恰好與管道系統的固有頻率相接近,其引起的管道振動對噪聲的貢獻最突出,同時也與水泵房房腔的固有頻率相接近,從而引起房腔共鳴發聲,使噪聲進一步被放大,以至于噪聲最大處高達105db ( a ) 。

Abstract : this paper compares central pump room with sepaterating pump room from their usual life , construtural time limits and cost of construction . it points out that in central pump room construction of housing estate ' s pump room should be adopted 文摘:從使用壽命、施工工期、經濟造價等方面將小區集中式泵房與分離式泵房建設的優缺點加以比較,指出未來的小區泵房建設應采用集中式泵房

The thesis analyses the signal of vibration and noise of water system in pump room through power frequency spectrum analysis and coherence analysis . meanwhile uses finite element method ( fem ) to investigate the characteristics of pipe system 論文通過功率譜分析、相干分析等方法對供水系統泵房內的管道系統進行振動與噪聲信號的分析,用有限元的方法分析管道系統的結構特性。

Whether the government has considered amending the relevant regulations with a view to applying different standards in regulating noise emission from pump rooms in buildings completed before and after 1973 ; if so , what the details are 有否考慮修訂有關的規例,以不同標準規管一九七三年之前和之后落成樓宇的泵房噪音若然,詳情為何?

Compact structure , small volume , low noise , outstanding energy conservation , easy to check and maintain , no need of pump room , gotten into working while being submerged into water , and great reduction of construction cost 整體結構緊湊、體積小、噪聲小、節能效果顯著,檢修方便,無需建泵房,潛入水中即可工作,大大減少工程造價。

From two sides of the design and construction , this paper expatiates the disposal of water supply and drainage pipelines , how to choose the pipe , the disposal of pump room and how to diminish the vibrancy of the pump groups 從設計和施工兩方面出發,論述了給排水管道的布置、給排水管材的選用及給水泵房的減振隔聲等內容。

Of the rationale for the government applying the same standard in regulating noise emission from pump rooms in buildings completed before and after 1973 ; and 政府以同一標準規管一九七三年之前和之后落成樓宇的泵房噪音,所持的理據為何及

The pump room should have been discarded . there is a transformer substation behind the river bank . can you find someone is preparing for the supper 泵房應該已棄置。在河堤的后面是一個變電站。你看到有人已經開始做晚飯了嗎?

And the company sets up pump room , water tower , adopting deep water pump , tank to provide water safeguard for producing and living 并建有泵房、水塔,采用深水泵、儲水池相結合的方式,為生產和生活用水提供了保障。

Protective devices in the on - site power source circuits at the generator shall allow instantaneous pick - up of the full pump room load 發電機現場電源電路中的保護裝置應能瞬時獲得全泵房負荷?

Of the criteria adopted in 1973 for determining the noise emission standard for pump rooms in buildings 在一九七三年厘定大泵房發出噪音標準的準則為何

Later , twd budgeted for the amount of nt 80 million and restored the pumping room to its original features 其后本處編列八千馀萬元修護,恢復唧筒室原
