浅析可燃气体探测器的安装规范

发布时间 2018-03-07     发布人: admin     浏览次数:670

可燃气体探测器选点应选择阀门、管道接口、出气口或易泄漏处附近方圆1米的范围内,尽可能靠近,但不要影响其它设备操作,同时尽量避免高温、高湿环境。      

可燃气体探测器用于大面积气体检测时可采用10~12平方米一个探头布置,也可达到检测报警效果。      

可燃气体探测器安装方式可采用房顶吊装、墙壁安装或抱管安装,应确保安装牢固可靠,同时应考虑便于维护、标定。

可燃气体探测器安装高度:检测氢气、天然气、城市煤气等比重小于空气的气体时,采用距屋顶1米左右安装;检测液化石油气等比重大于空气的气体时,采用距地面1。5~2米左右安装。

可燃气体探测器布线应采用三芯屏蔽电缆,单根线径大于1平方毫米,接线时屏蔽层必须接地。

可燃气体探测器现场走线应穿管,所用管子应符合消防要求,管子应与探头连接,以达到消防要求。

可燃气体探测器安装时应传感器朝下固定。

可燃气体探测器应在断电情况下接线,确定接线正确后通电;应在确定现场无可燃气泄漏情况下,开盖调试探头(对于隔爆探头SP-1102来说)。    

可燃气体探测器应至少每年标定一次,以确保检测精度。

Combustible gas detector location 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。
