Amount.The indicator light 12 and buzzer 13 for showing detecting state are also equipped on shell 1.Under normal conditions, indicator light 12 divides
For yellow, green, red trichromatism, standby, detection and three kinds of states of failure are respectively represented, while making buzzer 13 is adjoint to send out 1 sound, 2 sound
With continuous sound, to remind the working condition residing for testing staff's analyzer.Rechargeable supplying cell group is provided in shell 1
14, the portable applicability of equipment can be effectively improved.
For the ease of using, 1 back side of shell is provided with fixed mechanism, specifically, fixed mechanism be folding bracket or
Setting can be placed at the top of heating storage tank or be wrapped at operating personnel's arm and carry by adhesive type bandage.Shell 1
Outside can carry out effective protection waterproof and dampproof etc. with mating setting transparent silica gel protective case to equipment.
When being detected, the pernicious gas in rubber asphalt heating storage tank M enters gas-detecting cavity under the effect of air pump 2
3, first gas componant and content are analyzed by gas sensor, result is sent to liquid crystal display 11, then, gas later
Body enters gas absorption box 4, and harmful components therein carry out innoxious emptying after being absorbed by adsorbent.Specific steps are such as
Under：
The first step checks the connection air-tightness of air inlet pipe 5 and air pump 2, tubaeform collection gas port 6, it is ensured that after gas leak phenomenon, booting
Preheating 3-5 minute, at this time the yellow indicator lamp 12 on shell light, with 13 1 sound of buzzer short sound, prompt equipment in waiting for
Machine and pre- Warm status；
Air inlet pipe 5 is placed in rubber asphalt heating storage tank M by second step after checking and adjusting each detection parameters of analyzer,
Gas distribution situation in tank is observed by microcam 8, tubaeform collection gas port 6 is placed in the position of gas concentration rather moderate
It sets, while tubaeform collection gas port 6 being made to be located at tank mouth or less 20-50cm, start 2 intake-gas of air pump after 3-5 minutes, gas detection
The liquid of rubber asphalt generation is filled in chamber 3, at this point, the yellow indicator lamp 12 on shell extinguishes, green indicator light 12 lights,
With 13 liang of short sound of sound of buzzer, equipment is prompted to be in detecting state, when each gas content detection data on liquid crystal display 11
After stabilization, testing result is recorded；
Third walks, and air inlet pipe 5 is detached outside rubber asphalt heating storage tank M, tubaeform collection gas port 6 is made to be located in fresh air,
Keep air pump 2 aspirate 5-10 minutes, when instrument gas show value is down to 10 units or less, can shut down, to prevent sensor " in
Poison " causes to be lost.
So far, detection process is completed.
