怎么检查你的排烟罩是否合格?

发布时间:2019/01/08

测试应采用检验合格的专用测量仪表或采用符合现行国家标准(流量测量节流装置)规定的计量元件搭设的测量装置。漏风管测试装置可采用风管 式或风室式。风管式测试装置采用孔板作计量元件,风室式测试装置采用喷嘴作计量元件,最后测出的实测值与设计给定的数值不应小于10%为合格。
  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.

  (1)应设置在该排烟系统最高排烟口的上部,并应设在用耐火极限不小于2.5h的隔墙隔开的机房内,济南厨房排烟机房的门应采用耐火极限不低于0.6h的防火门。
  (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.
  (2)为了方便维修,排烟罩外壳至墙壁或设备的距离不应小于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.
  (3)排烟罩与排烟道的连接方式应合理。实践证明,因为排烟罩与排烟风道连接方式不正确,常常会引起风机的性能显著下降。

  (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.
  (4)排烟罩与排烟口应设有连锁装置。当任何一个排烟口开启时,济南厨房排烟即能自动启动。即一经报警,确认发牛火灾时,由手动或由消防控制室遥控开启排烟口,则排烟罩立即投入运行,同时立即关闭着火区的通风空调系统。首先核查风管严密性试验是否符合设计和现行施工质量验收规范规定,若不符合要求,有无进行返修处理,处理结果是否符合规定。核查测定所使用的仪器仪表是否有检定证书,其精度是否符合要求,各项记录的测定日期是否在其检定有效期内。对照施工图纸,核对试验项目中系统是否齐全,试验数据是否准确、真实,签证是否齐全。
  (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.
