才能保证仪器的使用寿命会更长。 The gas detector only needs to be regularly inspected and maintained within a certain period of use. Only by mastering the correct inspection and maintenance methods can the instrument's service life be longer. 相同的选择标准样品气体测量介质是不同的,有不同的车站。 1) In principle, a standard sample gas that matches the measurement certification and test gas is used. The same choice of standard sample gas measurement medium is different and there are different stations. (2) Before the inspection, detect that the surrounding environment is not flammable. 连续样品气体通过管道输送进来,为了确保校准精度。 If a flammable gas detector, the valve cover needs to be removed, filled with a certain amount of air to clean, and continuous sample gas is delivered through the pipeline in order to ensure calibration accuracy. (3) When measuring mixed hydrocarbon gas, isobutane is the first sampling gas, followed by propane. 、丙烷等是容易的和稳定的单组分燃料作为样品气体。 (4) For non-hydrocarbon mixtures or the lower explosive concentration of heat generated by gas burning more hydrocarbon mixtures, if necessary, butane, isobutane , propane, etc. can be used as easy and stable one-component fuel as the sample gas. 整范围。 At this time, it is necessary to adjust the adjustment range based on a certain detection alarm signal conversion relationship . 同的,因此,使用和维修方法是类似的。 There are many types of flammable gas alarms and models for the use and maintenance of flammable gas alarms, but the basic circuit principles are the same , so the use and maintenance methods are similar. Now, the usage and repair methods are described as follows: (1) The service life of the detection element and compensation element is usually 3-5 years. 。 The conditions of use and maintenance under the correct conditions can extend its service life . (2) Press the test button to alarm. Press the test button once a week to check whether the alarm system is normal. 和范围。 Check the zero sum range of the calibration alarm every 2 months . (3) Always check if there is any accident in the detector into the water. Detector ventilation hoods are tested during instrumentation and should be removed for cleaning to prevent blockages. (4) The detector shall not be used beyond the specified range for fire and explosion-proof devices. Do not use detectors in place of sulfur. 浓度低于爆炸下限尽可能的条件下使用,否则,可能烧坏元素。 The detector should be used under conditions where the concentration of flammable gas is below the lower explosive limit as much as possible, otherwise, elements may be burned. (5) Hot wire semiconductor detectors must not be hypoxia under conditions of use. 只要正确掌握以上关于检测维护可燃气体检测仪，我们才能在安全的工作环境中进行工作，才能真正的 做到“开开心心上班，安安全全回家。 Do not use a large number of flammable gas sensors, as long as you have a good grasp of the above- mentioned detection and maintenance of flammable gas detectors, we can work in a safe working environment, and we can truly "go to work happily and go home safely.
