B型電火花真空檢測器
一、電火花真空檢測儀概述
本產(chǎn)品利用高頻電火花檢測各種器件真空程度，具有安全可靠,使用方便的特點,是電子管、陰極射線管、氣體激光管、各種燈泡等玻璃抽氣產(chǎn)品檢測真空程度的必須儀器。
二、電火花真空檢測儀主要性能
1.火花束長度：≥20mm
2.工作方式：間歇使用
3.溫升：連續(xù)使用半小時,不超過60℃
4.適用電源：~220V,±10%
5.電源頻率：50±3HZ
6.耗電功率：不大于30W
7.檢測范圍：200~10-3托
8.重量：0.6公斤
三、電火花真空檢測儀工作原理
接通電源后由L1與CD產(chǎn)生振鈴，在CD的觸點之間發(fā)生電火花現(xiàn)象，激勵C及L2組成的回路串聯(lián)諧振，經(jīng)L3感應產(chǎn)生高頻電壓，然后由放電簧F放出高頻電火花，即可使用。
四、電火花真空檢測儀調整及使用
先把放電簧插頭插入前面插座，然后將電源插頭插入220V/50HZ交流電源，接通開關，此時在放電簧端應看到紫色火花。將放電簧移近任何金屬物體時，應產(chǎn)生不少于三條火花線，長度不短于20MM。如無火花產(chǎn)生或火花線甚少，或長度甚短，則可調節(jié)檢測器后面的旋鈕，便產(chǎn)生火花，并調節(jié)火花至zui多zui長為止。
火花正常后，便可對電子管或其他玻璃真空容器檢測其真空程度。
將放電簧對準被測器件，如其真空度相當高時，則紫色火花局限在玻璃壁外。若真空度不高或非真空時，放電簧端的高頻電火花（高壓）引起容器內氣體電離，并產(chǎn)生輝光。
五、電火花真空檢測儀注意事項
1.本產(chǎn)品供間歇使用（即時開關）如需連續(xù)使用（即長時間開著），應需注意，勿使溫升超過120℃，以免燒毀線圈。
2.使用時，人體不能靠近或接觸高壓線圈圓錐形部分，否則有強烈火花電弧躍出會將線圈燒壞。
3.在測玻璃器件時，必須來回移動不要停留，若時間超過五秒鐘以上，電火花易將玻璃擊穿。
4.在檢測器使用一段時間后，接觸部分可能會燒濁，可用砂布砂光后繼續(xù)使用。
5.平時不用時應將調節(jié)旋鈕旋出（即逆時針旋轉），使用時把旋鈕緩緩旋入（順時針方向旋轉），但應防止接觸頭短路，將震動線圈燒壞。萬一發(fā)生接觸頭短路，（或其他故障）時將內部拆卸出來檢修。
B type edm vacuum detector
An overview, edm vacuum tester
This product use of high-frequency electric spark testing device, vacuum degree, have a safe and reliable, easy to use, the characteristics of tube, a cathode ray tube, gas laser tube, all kinds of light bulbs and other glass extraction product testing the vacuum degree of must equipment.
Second, the electric spark vacuum gauge performance
1. The length of fire bouquet: 20 mm or higher
2. Work style: intermittent use
3. The temperature rise: continuous use half an hour, less than 60 ℃
4. Apply power: ~ 220 v, + / - 10%
5. Power frequency: 50 + 3 hz
6. Electricity power: no more than 30 w
7. Test: the range of 200-10-3
8. Weight: 0.6 kg
3, edm vacuum working principle of the detector
After turning on the power supply is produced by L1 and CD ringing, edm ur between the contact of the CD, the incentive of C and L2 loop series resonance, the L3 induction to produce high-frequency voltage, then the discharge spring F emit high-frequency electric spark, can be used.
Four, electric spark vacuum tester adjustment and use
The discharge first spring plug into the socket, and then insert the plug into 220 v / 50 hz ac power, turn on the switch, at this point in the spark discharge spring end should see purple. Move discharge spring nearly any metal objects, should be not less than three spark producing line, the length of not less than 20 mm. If there is no spark or spark producing line, or length is very short, can adjust the detector at the back of the knob, then produce sparks, and adjust the spark to the maximum of the longest.
Spark is normal after, can on the tube or other glass vacuum container testing the vacuum degree.
Aim the discharge in spring, the device being tested as the vacuum degree is quite high, the purple spark limited outside the glass wall. If the vacuum degree is not high, or the vacuum, spring the high frequency electric spark discharge (high pressure) container gas ionization, and generate glow.
Five, the electric spark vacuum tester
1. This product is for the use of intermittent (instant switch) for continuous use (open) for a long time, should pay attention to, don\'t make the temperature over 120 ℃, so as to avoid burning coil.
2. When used, the body can\'t close to or contact with high voltage coil conical part, otherwise a strong spark arc spring coil will be burn out.
3. When the glass measuring device, must move back and forth and not to stay, if the time is more than five seconds, electric spark breakdown easy to glass.
4. Use after a period of time in the detector, the contact part may burn turbidity, available emery cloth continue to use after sanding.
5. At ordinary times need not when adjusting knob should be spin out (counterclockwise), when using the knob slowly screwing in (clockwise), but should prevent contact short circuit, vibration coil burn out. One thousand contact head short circuit, (or other malfunction) when the internal remove out maintenance.
