淺析可燃氣體探測器的安裝規範

發布時間 2018-03-07     發布人: admin     瀏覽次數:827

可燃氣體探測器選點應選擇閥門、管道接口、出氣口或易泄漏處附近方圓1米的範圍內,盡可能靠近,但不要影響其它設備操作,同時盡量避免高溫、高濕環境。      

可燃氣體探測器用於大麵積氣體檢測時可采用10~12平方米一個探頭布置,也可達到檢測報警效果。      

可燃氣體探測器安裝方式可采用房頂吊裝、牆壁安裝或抱管安裝,應確保安裝牢固可靠,同時應考慮便於維護、標定。

可燃氣體探測器安裝高度:檢測氫氣、天然氣、城市煤氣等比重小於空氣的氣體時,采用距屋頂1米左右安裝;檢測液化石油氣等比重大於空氣的氣體時,采用距地麵1.5~2米左右安裝。

可燃氣體探測器布線應采用三芯屏蔽電纜,單根線徑大於1平方毫米,接線時屏蔽層必須接地。

可燃氣體探測器現場走線應穿管,所用管子應符合消防要求,管子應與探頭連接,以達到消防要求。

可燃氣體探測器安裝時應傳感器朝下固定。

可燃氣體探測器應在斷電情況下接線,確定接線正確後通電;應在確定現場無可燃氣泄漏情況下,開蓋調試探頭(對於隔爆探頭SP-1102來說)。    

可燃氣體探測器應至少每年標定一次,以確保檢測精度。

Combustible gas detector locations should choose the valve and pipe outlet interface, or easy to discharge a radius of 1 meters range near the site, as close as possible, but do not affect other equipment operation, and try to avoid high temperature and high humidity environment.

When the gas detector is used for large area gas detection, 10~12 square meters of a probe can be used and the effect of detection and alarm can be achieved.

The installation of flammable gas detectors can be installed by roof lifting, wall installation or pipe holding. The installation must be reliable and reliable. Meanwhile, it should be considered for easy maintenance and calibration.

The installation height of flammable gas detector: when detecting hydrogen, natural gas, city gas and other gases less than air, it will install 1 meters away from the roof. When detecting liquefied petroleum gas and other gases larger than air, it will install 1.5 to 2 meters away from the ground.

A three core shielded cable should be used for the wiring of a combustible gas detector, with a single line diameter of more than 1 square millimeters, and the shielding layer must be grounded when the wiring is connected.

Combustible gas detector field wire wear pipe, the pipe should meet the requirements of fire fighting, the pipe should be connected with the probe, in order to achieve the requirements of fire fighting.

When a combustible gas detector is installed, the sensor should be fixed at the bottom.

The combustible gas detector should be connected under the power failure condition, and it is sure that the electricity will be energized after the connection is correct. We should open the cover and debug the probe (for the flameproof probe SP-1102) when we confirm the scene of no gas leakage.

The combustible gas detector should be calibrated at least once a year to ensure the accuracy of the detection.
