Description
Technical field
The present invention relates to the technical field of gas leakage hunting apparatus, more particularly to the special leakage detection apparatus of a kind of halogen gas and auxiliary
Help start structure.
Background technology
The fluorine type gas of high frequency magnetic field ionization type（Or other halogen gas）Special leakage detection apparatus, the leakage detection apparatus is extensive
Applied to products such as sf6 quantitative leaks, air-conditioning leak detections；In some environments (humidity, dust, air pressure), part start is had not
Successful phenomenon, it is impossible to normal to use, it is necessary to repeatedly frequently start, but under many circumstances, still can not normal boot-strap so that
Cause part of devices to overheat and burn out detector, cause device to be damaged.
The fluorine type gas leakage detection apparatus of high frequency magnetic field ionization type, under normal circumstances, the high-frequency generator in its detector
Electrode slice on produce high frequency ionization magnetic field should be able to ionize the low-pressure air in ionization chamber（Produce dark violet tint
Light, we term it build-up of luminance）, now ionization chamber is a load for oscillator, thus oscillator export one it is relatively low
Voltage is about in below 2v, and measurement meter reading is within 100, and at this time instrument enters normal operating conditions.
But many times, high-frequency generator is under the influence of by ambient temperature, humidity, air pressure etc., and efficiency decreases,
The high frequency magnetic field now produced on high frequency coil electrode not enough, is insufficient to allow low-pressure air in ionization chamber to ionize due to energy, this
When ionization chamber for oscillator, very little is loaded, even if so output end has a higher output voltage, typically existing
Any purple glow is there will not be in 20v or so, ionization chamber, instrument can not carry out normal work, we term it start not into
Work(.
At present, in the market does not occur the warp for the special leakage detection apparatus of halogen gas that can solve the problem that high frequency magnetic field ionization type
Perseverance can not normal build-up of luminance problem of start-up equipment, for this it is regular can not normally build-up of luminance is started shooting the problem of, one in industry
The method that the actual cause and essence of the problem solve the problem that produces can not directly be found.
The applicant has also once attempted following methods, probes into the actual cause for causing system not successfully start up, then
Solve the certain problem started.
Method one：Expand the oxygen supply amount of ionization chamber, help to start；Those skilled in the art will ionize chamber enclosure from
It is sealed to be adjusted to semi open model, the successful probability of start can be improved.
Method two, by the spy-hole covered on ionization chamber expand, increase light entrance, help to start；Such change pair
It is effective in improving start success rate, but as accurate device and heater members, is not suitable for open exposed, dust etc.
Pollution can cause product failure.
Method three, increase heating element heater inside ionization chamber, reduce the humidity of ionization chamber, help to start, test effect is not
Substantially.
Method four, applicant have understood that being probably that humidity is too high causes ionization chamber when vacuumizing, due to moisture in air
Liquid is converted into gaseous state, volume expansion, therefore vacuum and is unable to reach, so start is unsuccessful.Built for this applicant
Discuss customer when in use, should be started shooting under air conditioner surroundings, after starting shooting successfully, be moved to the place needed to use.But result is sent out
Existing, such starting-up method is nor 100% reliable start.
Method five, applicants have discovered that sometimes, if the vacuum in increase ionization chamber, can increase sometimes
Plus start successful possibility, therefore, there is such description in the operation instruction of product：If " liquid crystal display is 1, is shown
Startup is unsuccessful, detector air inlet is please covered with thumb 3-5 seconds, then unclamped, repeated multiple times ", but in actual use
Solution starting problem not being not the property of can determine that such process each time.
Method six, the material for changing probe body, because in actual tests, removing probe body can be relatively good
Successful probability of once starting shooting is improved, whether it is that the material of shell changes the magnetic field in ionization chamber that the applicant suspects, so
Used the different materials such as aluminium alloy and ABS plastic, stainless steel to be compared experiment, as long as but experiment result be to have filled shell
Will have an impact, shell is little using which kind of Effect of Materials.
Therefore, although even if those skilled in the art make a variety of trials as the applicant, still can not yet
The actual cause and solution of ionization chamber internal oscillator build-up of luminance start are looked for, why in the market this also can just explain
Regular still without the special leakage detection apparatus of halogen gas for occurring can solve the problem that high frequency magnetic field ionization type normally can not open build-up of luminance
