CO检测报警仪、可燃气体测爆仪及氢气检漏仪的使用方法
CO气体检测报警仪、可燃气体测爆仪及氢气检漏仪的使用方法一、一氧化碳气体检测报警仪（简称CO测报仪）1、一氧化碳气体检测报警仪的测定范围是CO含量0—2000PPM，开始声响报警范围为0—300PPM可调，一般调整到CO含量达到50PPM开始报警；2、焦炉煤气与空气混合时的爆炸浓度范围是：混合物中焦炉煤气含量4.7—38%。
即爆炸下限为4.7%，混合物中焦炉煤气含量低于4.7%不会爆炸；爆炸上限为38%，混合物中焦炉煤气含量高于38%不会爆炸；3、焦炉煤气中CO的含量在7%左右，即其中CO含量为70000PPM。
当焦炉煤气与空气混合时，如焦炉煤气含量为4.7%，则混合物中CO含量应为：70000×4.7%=3290PPM 。
如混合物中CO含量为200PPM，则其中焦炉煤气含量应为：200/70000=0.286%；4、焦炉煤气与空气的混合物中，焦炉煤气含量为4.7%时，混合物中CO含量为70000×4.7%=3290PPM，大于一氧化碳气体检测报警仪的测定范围———2000PPM。
所以一氧化碳气体检测报警仪的主要作用是防止CO中毒，而不是测定气体是否会爆炸。
但是对于焦炉煤气与空气的混合物来说，如果其中CO含量低于2000PPM的话，它肯定低于爆炸下限，所以一氧化碳气体检测报警仪在一定条件下可以用来确定可燃气体混合物是否能够爆炸（对于液化石油气就不行）；5、一氧化碳气体检测报警仪不可长期工作在CO含量较高的条件下，以免仪器中毒失灵。
二、可燃性气体检测报警仪（简称“测爆仪”）1、测爆仪能检测空气中可燃气体爆炸下限浓度的百分比含量，其测定范围是爆炸下限浓度的0—100%，开始声响报警范围为爆炸下限浓度的5—60%可调，一般调整到爆炸下限浓度25%开始报警；2、焦炉煤气与空气混合物的爆炸下限为4.7%，这相当于爆炸下限浓度的100%。
由此可知，当测爆仪上的指字为15%时，混合物中含焦炉煤气为：4.7%×15%=0.705%三、氢气检漏仪⑴SQJ—ⅠA型1、SQJ—ⅠA型氢气检漏仪能检测空气中氢气爆炸下限浓度的百分比含量，其检测范围是爆炸下限浓度的0—100%，氢气与空气混合物的爆炸下限为4%，如果按ppm计，其检测范围是0~40000ppm。

During this time the LCD displays a countdown to completion and the Probe Tip LED is amber. The following operations occur:The Wide Range Sensor® reaches operating temperature.A system self-test is run.Upon successful completion of the above tasks the instrument zeroes itself and automatically switches to normal operation. If an error is detected theinstrument will display an error code (see Section 10).3.2ShutdownTo power-down the HY-ALERTA™ 500, press and hold the ON/OFF button forapproximately two seconds until the Controller LCD display turns off.3.3Battery LevelAfter power-on the BATTERY LED indicates the current battery level (times areapproximate and may vary as the battery ages):Color MeaningGreen more than 60 minutes of operation remainingAmber approximately 15 to 60 minutes of operation remainingRed less than approximately 15 minutes of operation remainingA fully charged battery should last 10 to15 hours, depending on use.There is a small load on the battery when the unit is powered off. This load will discharge the battery of the unit in it’s powered off state in about 6 months.Customers that do not use the device frequently should charge the batteryand perform a bump test with hydrogen gas every one to three months tokeep the battery charged and ready for use.3.4Normal OperationDuring normal operation the instrument is detecting and reporting thehydrogen concentration near the probe tip sensor. Hydrogen readings aredisplayed on the controller LCD and the probe tip LED bar graph array. Note that due to the extreme sensitivity of the sensor, it may take several minutes to return to a near zero (less than 0.001%) reading after exposure to hydrogen. If the instrument does not return to an indication of less than 0.001% after 5minutes in a hydrogen-free environment, then invoke the Reset operation (See Section 3.6).The upper line of the Controller LCD indicates a numerical value or range for the percent hydrogen concentration or peak hydrogen value. The lower line is used to display the hydrogen meter, a logarithmic bar graph ranging from0.001% (10 ppm) to 100% hydrogen by volume. An open box on the bar indicates the last peak value obtained and filled boxes indicate the current value. The following figure describes how to interpret the hydrogen meter:The Probe Tip LED Indicator shows an increase or decrease in hydrogenconcentration. Leak detection is accomplished by watching the Probe Tip LED and the bar graph array and moving the sensor around a potential hydrogen leak.The number of yellow LEDs lit in the Probe LED bar graph array indicates detected hydrogen concentrations in four ranges as noted below:3.5Hydrogen-Free AreasFor the purposes of this document a hydrogen-free area is one with less than5ppm of hydrogen in the air.It may be difficult to find a hydrogen-free area in a facility where hydrogen is used. Nearby rooms, or even the entire building, may not be hydrogen free.To check these areas reset or zero the sensor outside, away from any hydrogen tanks, pipes, or other potential sources. Walk through the facility, watching the sensor. It is surprising how far low levels of hydrogen can spread.If the sensor is zeroed or reset in hydrogen, there will be a negative offset in the readings that could compromise the sensor’s ability to find small leaks.3.6Reset OperationThe Reset Operation is used to speed recovery from hydrogen exposure.It can be invoked from the keypad while in the top menu level (measuring hydrogen) by pressing and holding ◄►(left and right arrow buttons simultaneously) or from the Reset Menu (see Section 4). Once invoked the user is asked to confirm the operation by pressing the ENTER key. Pressing any other key will abort the operation. During Reset the LCD indicates a count down to completion and the Probe tip LED is yellow.3.7Zero OperationThe Zero Operation is used to zero the hydrogen reading if the instrument is reporting low levels (0.001% to 0.01%) of hydrogen when no hydrogen is present. This operation can be invoked from the keypad while in the top menu level (measuring hydrogen) by pressing and holding ◄ (left arrow button) or from the Reset Menu (see Section 4). Once invoked the user is asked to confirm the operation by pressing the ENTER key, pressing any other key will abort the operation.4. Keypad4.1 Numerical ChangesIn the following sections when queried to change a numeric value the ▲ (up arrow) and ▼ (down arrow) keys are used to increment/decrement the value based on the selected digit. If the ones digit is selected the value willincrement/decrement by one (9 increments to 10, 10 decrements to 9). The ◄ (left arrow) and ► (right arrow) keys are used to select another digit. Tochange a value of 0 to 100 first select the hundreds digit then press the ▲ up arrow. Pressing ◄► (the left and right arrows simultaneously) will clear any changes made and restore the previous value. Once the correct value is displayed press the ENTER key to save it. 4.2 Top Level Keypad FunctionsWhile in the hydrogen measurement screen, the keypad has these functions:Key Function ENTER Go to the Information Display menu . ▲ Display the peak hydrogen reading. ▼ Display the current hydrogen concentration. ► Clear the peak hydrogen value. ◄ Zero the sensor (see Section 3.7). ◄► Reset the sensor (see Section 3.6).4.3 General Keypad Functions (Also See Section 11)4.4 Information DisplayThe Information Display menu allows the user to view useful information about the instrument including firmware revisions, serial number, and calibration date. Enter it by can be entered by pressing and holding the ENTER button. 4.5 Firmware Rev:This displays the sensor pod and controller firmware.

Understanding this behavior allowsa more effective search for hydrogen leaks.The hydrogen plume from a leak generally spreads in a roughly conical shape that is easily disturbed by environmental conditions. Certain conditions such as pressure, temperature, and leak size may act together to change the shape of the hydrogen plume from a cone to a laser-like beam. This makes finding aleak more difficult.If the sensor element is near (and above) the leak, the concentration will likely be higher but the leak may be difficult to locate. As hydrogen dissipates theconcentration decreases. Generally, greater distances will increase thechance of intercepting the leak stream, but if the sensor is too far away, theresponse may be too weak to detect.When drafts or air currents are present, hydrogen will tend to be dispersed.Testing for hydrogen leaks downwind of the leak area may increase thechance of detecting the leak.If hydrogen is rising in an enclosed building the hot air near the ceiling mayslow the hydrogen’s rise. Thus, sensing hydrogen near ceiling areas with hightemperatures present may not be as effective as at a lower level.Low temperatures can also affect the behavior of hydrogen. Hydrogen stored in a liquid state is at an extremely low temperature. The low temperature ofany escaping hydrogen will be of a higher than normal density and mayinitially move downward. As the hydrogen warms, it will begin to rise upward.When checking for a leak in areas where liquid hydrogen is stored, check both above and below the area of concern.6.Bump TestA bump test is recommended every three months. The purpose of a bump testis to verify that the sensor is active, detecting hydrogen and verifying that the sensor is within the pre-set factory tolerance for accuracy. To performs a bump test perform the following:In a non-hydrogen environment, power on the instrument. Once theinstrument has gone through its standard 10 minute warm-up, use thecalibration cup that accompanies the HY-ALERTA™ Model 500, and apply 2% hydrogen to the probe sensor. Let the 2% hydrogen flow for a minimum of 3-5 minutes. After 3-5 minutes the concentration value registered on the LCDdisplay should read between 1.6% to 2.4%, which is within factory tolerance. If the 2% reading is below 1.6% or above 2.4% the instrument should go through a Verification test as outlined below.7.VerificationVerification is performed in a non-hydrogen environment to confirm that theHY-ALERTA™ Model 500 is operating properly and within the pre-set factorytolerance for calibration. The recommended verification interval is every 12months, or after a 2% bump test has been performed and the indicated values on the LCD display were outside the stated tolerance as outlined in Section 6.If the verification fails, then it should be repeated one more time.The HY-ALERTA Model 500 requires calibration only if it fails the secondverification. It cannot be field calibrated and must be returned to h2Scan for calibration service. An optional NIST traceable certificate is available uponrequest.7.1GasesVerification requires the availability of the following certified gases:2.00% hydrogen by volume in air (20,000 ppm)0.10% hydrogen by volume in air (1000 ppm)Zero grade, hydrogen-free air.

铝屑安装氢气报警规范
铝屑安装氢气报警规范
1、安装固定式氢气报警器时，已经安装到位，不得轻易改动，要清楚的知道哪些点可能存在泄漏情况的产生，如若出现泄漏泄漏压力可能达到多少?其气流方向可能是哪?以此来确定氢气报警探头的安装位置，划分出Ⅰ、Ⅱ、Ⅲ三种等级，表明泄漏的严重程度。
2、根据所在场所的气流方向、风向等具体因素，判断当发生大量泄漏时，有毒气体的泄漏方向。
3、根据泄漏气体的密度(大于或小于空气)，结合空气流动趋势，综合成泄漏的立体流动趋势图，并在其流动的下游位置作出初始设点方案。
4、研究泄漏点的泄漏状态是微漏还是喷射状。
如果是微漏，则设点的位置就要靠近泄漏点一些。
如果是喷射状泄漏，则要稍远离泄漏点。
5、根据国家相关规定与标准，对于存在有较大泄漏可能的场所，每相距10~20m应设置一个监测点。
6、由于氢气的比重比空气轻，泄漏后会向上飘，所以需要将氢气报警器安装在泄漏点上方。
7、对于开放的氢气泄漏，如果缺乏良好的通风条件，很容易在某一部位积聚，造成氢气浓度标，产生事故。
8、氢气报警器的安装高度应在170cm左右，便于工作人员能够看到仪表屏显示、和维修人员的日常维护。
9、氢气报警器周围不能存在较大影响的强磁场，避免对仪表产生干扰，同时注意屏蔽线接地牢靠。
