測試應(yīng)采用檢驗合格的專用測量儀表或采用符合現(xiàn)行標(biāo)準(zhǔn)(流量測量節(jié)流裝置)規(guī)定的計量元件搭設(shè)的測量裝置。漏風(fēng)管測試裝置可采用風(fēng)管 式或風(fēng)室式。風(fēng)管式測試裝置采用孔板作計量元件，風(fēng)室式測試裝置采用噴嘴作計量元件，后測出的實測值與設(shè)計給定的數(shù)值不應(yīng)小于10%為合格。
Testing should adopt special measuring instruments which are qualified or measuring devices which meet the current national standards (flow measurement throttling devices). The air leakage tube test device can adopt the air duct type or the air chamber type. The orifice plate is used as metering element in the air duct type test device, and the nozzle is used as metering element in the air chamber type test device. The final measured value and the design given value should not be less than 10% qualified.

Kitchen smoke exhaust in Jinan
?。?）應(yīng)設(shè)置在該排煙系統(tǒng)高排煙口的上部，并應(yīng)設(shè)在用耐火極限不小于2.5h的隔墻隔開的機(jī)房內(nèi)，濟(jì)南廚房排煙機(jī)房的門應(yīng)采用耐火極限不低于0.6h的防火門。
(1) The upper part of the highest exhaust outlet of the smoke exhaust system should be set in the machine room partitioned by partitions whose fire resistance limit is not less than 2.5 hours, and the door of the smoke exhaust machine room of Jinan kitchen should be fireproof door whose fire resistance limit is not less than 0.6 hours.
?。?）為了方便維修，排煙罩外殼墻壁或設(shè)備的距離不應(yīng)小于60cm.
(2) In order to facilitate maintenance, the distance from the hood shell to the wall or equipment should not be less than 60 cm.
?。?）排煙罩與排煙道的連接方式應(yīng)合理。實踐證明，因為排煙罩與排煙風(fēng)道連接方式不正確，常常會引起風(fēng)機(jī)的性能顯著下降。
(3) The connection mode between exhaust hood and exhaust flue should be reasonable. Practice has proved that the performance of the fan is often significantly reduced because of the incorrect connection between the exhaust hood and the exhaust duct.
?。?）排煙罩與排煙口應(yīng)設(shè)有連鎖裝置。當(dāng)任何一個排煙口開啟時，濟(jì)南廚房排煙即能自動啟動。即一經(jīng)報警，確認(rèn)發(fā)?；馂?zāi)時，由手動或由消防控制室遙控開啟排煙口，則排煙罩立即投入運行，同時立即關(guān)閉著火區(qū)的通風(fēng)空調(diào)系統(tǒng)。核查風(fēng)管嚴(yán)密性試驗是否符合設(shè)計和現(xiàn)行施工質(zhì)量驗收規(guī)范規(guī)定，若不符合要求，有無進(jìn)行返修處理，處理結(jié)果是否符合規(guī)定。核查測定所使用的儀器儀表是否有檢定證書，其精度是否符合要求，各項記錄的測定日期是否在其檢定有效期內(nèi)。對照施工圖紙，核對試驗項目中系統(tǒng)是否齊全，試驗數(shù)據(jù)是否準(zhǔn)確、真實，簽證是否齊全。
(4) The smoke hood and the smoke outlet shall be equipped with interlocking devices. When any smoke outlet opens, the kitchen smoke exhaust in Jinan can start automatically. That is to say, once the alarm is given and the cattle fire is confirmed, the smoke exhaust outlet is opened manually or remotely by the fire control room, the smoke exhaust hood will be put into operation immediately, and the ventilation and air conditioning system in the fire area will be closed immediately. Firstly, check whether the air duct tightness test meets the requirements of design and current construction quality acceptance criteria. If it does not meet the requirements, whether it has been repaired or not, and whether the treatment results meet the requirements. Verify whether the instrument used in the test has a certificate of verification, whether its accuracy meets the requirements, and whether the determination date of each record is within the validity period of its verification. Comparing with the construction drawings, check whether the system in the test project is complete, whether the test data is accurate and true, and whether the visa is complete.
