    # TEOM操作SOP (楠梓貨櫃) ###### tags: `高雄貨櫃` [toc] **重要的小tip:** 1. 換濾紙就要做側漏及流量校正 先做測漏 2. 每個禮拜清理impactor 3. 流量計用 033/2(採樣) 033/1(bypass) 4. teom流量的值要給Qa 也就是真值 Qs是經過流量計溫度壓力校正後的 可是teom自己會對溫度壓力進行校正 因此不需要重複校正 5. 三點校正 一大一小一中間 中間值要最準 6. 側漏 開關開關開 各等一分鐘 7. 流量校正 先做採樣管 然後bypass 8. bypass的管子只能用綠色的管子 綠色管子接碳管 再接流量計 ### 換濾紙 cooler濾紙,位置要在base(`Instrument Condition` → `FDMS Module`)(確定切在Set up)`Service` → `Instrument Control` → `Set up` 如果要移到reference`Service` →`Advance` →`Test FDMS Valve` → `Test` 一個月或45% loading時換濾紙,順便校正 1. 先拍螢幕 (紀錄頻率,換完後要比對) 2. 先換小filter(TEOM濾紙),再cooler濾紙 (47MM濾紙,要在base的位置) 3. 換完後之Cooler會出現錯誤,要慢慢降到4oC錯誤才會消失。 Instrument conditions → FDMS Module可看溫度 更換TEOM小濾紙及47 mm濾紙步驟 (螢幕上也會有顯示步驟) 4. `instrument control` → `set up` → `back` → `maintenance` → `replace TEOM filter(s)` (別選advanced,會沒有步驟顯示)→ 照步驟走 `[打開黑盒子(小心o-ring掉下來,注意放回去的方向)) → 將舊的取下 → 將同一面上新的放上去 → 再放一片新的在旁邊 → 黑盒子蓋上 → 按螢幕下一步,跑五分鐘]` → 跑完按下一步,開始換47 mm濾紙 (在換此濾紙時不需要按螢幕,最後換完再按) → 轉開cooler → 螺絲起子將兩個螺絲取下 (卡在裡面的管子也一起取下,防止不見) → 拔開灰色的,藍色的取出,並輕轉開 → 換新的濾紙上去 (粗糙面朝上,亦即朝儀器),並把藍色蓋子蓋上 → 將全部塞回去並鎖上螺絲即可 → 按`Finish` ![](https://i.imgur.com/YEvsTI5.jpg) 5. `Service` → `instrument control` → `Run` → `back` ### 校正 #### 測漏校正 (更換濾紙的時候,可以順便做) Base走中間,reference走側邊 (先看螢幕顯示閥的位置在哪裡,就走哪) Base和reference的步驟一樣 1. 先按`Instrument Control` -> `Setup` -> 按`Service` -> `Verification` -> `Leak Check` -> `Next` -> **看儀器上面寫哪一個** -> `Verify Base/Reference Leak Check` 3. 把小filter 拿下(左上角的濾紙拿下來 放到右下角) -> 等**樓上**把控制閥換到Cyclone的位置 ->打開控制閥 4. 拔VACUUM(跟PUMP連接的地方)的綠管(手壓著金屬環 另一隻手拔),跑一分鐘 5. 裝回管子VACUUM (檢查綠管要插到底) 6. **樓上**: 拔香菇頭 -> 裝leak check閥,並慢慢關閉,跑一分鐘 7. 將leak check閥,慢慢打開 8. 將leak check取下,裝回pm1.0的頭 9. 跑完Base及Reference,最後到成功畫面後,把filter放回去 ::: warning 1. 測漏的主流幾乎要是零 才沒問題 1. 一開始可以直接把閥放在上面(開著的狀態),filter移開 ::: 快速測漏 (若都ok,可三個月校正一次即可): 1. 裝上側漏頭(開著的狀態) 2. 不開pump,把filter拿掉 3. `Instrument condition` → `Flow rate` (先看flow rate的零點,拍照) 4. 把側漏頭慢慢關起來,看flow rate的變化是否和零點一樣 #### 溫溼度校正 (必須在流量校正前做) `Service`>`calabration`>`ambient` 藉由外部儀器量測到的溫度及濕度數值直接填入即可 #### 流量校正 做完測漏按`Back` -> 按`Service` -> `Calibration` -> `Flow Calibration` -> `Next` -> `Direct Flow Device`-> `Next`-> `Calibrate Bypass Flow`-> `Next`-> 螢幕顯示Bypass Flow rate lpm(在貨櫃裡面用流量計)(第一點會比較低,第二點會比較高,第三點會較接近)->用板手轉開,裝上流量計 螢幕顯示 Calibrate Main Flow(到樓上用流量計) 把Bypass管子接回去,量Total 流量(樓上量,要接近13.67) ![522DB024-E03C-429E-A917-FEBA2BDDD9DB](https://hackmd.io/_uploads/rko8PtfLC.jpg) 照著儀器說明即可 (direct flow) 快速測流量 (若都ok,可三個月校正一次即可): 1. 將側邊流bypass塞起來,檢查主流量是否為**3 lpm** 2. 側邊流bypass的紅色管斷開,檢查bypass流量是否為**13.67 lpm** 3. 紅色管接回去後,到貨櫃上方採樣管,檢查總流量是否為**16.67 lpm** ※ (16.67 lpm = 13.67 lpm (by pass) + 3 lpm) --- 1. Calibration->flow calibration 2. 固定螺絲 轉開-> Direct flow device->calibrate main flow 3. 回報流量 輸入按Enter --- 1. 做跟樓上一樣的事 2. 最後一筆誤差1%內 即通過流量校正 ### trouble shooting 1. 每周下去貨櫃都要取 TEOM data,下載完後檔案後要將其打開,檢查數據的時間範圍是否有從自行 edit 的時間點到當下進行下載的時間 2. 如果下載的檔案在某個時間點之後就沒有數據的話,可能為 TEOM 儲存 data 的CF card(類似memory card的東西)有損毀的情況,需要聯絡工程師進行處理。 3. 放濾紙的小黑盒裡有片經常會掉落的O-ring,是靠近左上角的部分,重新放回去的方向是較厚的那一端要朝上 5. **下載的檔案在某個時間點之後就沒有數據** 每周下去貨櫃都要取 TEOM data,下載完後檔案後要將其打開,檢查數據的時間範圍是否有從自行 edit 的時間點到當下進行下載的時間,若沒有數據,可能為 TEOM 儲存 data 的CF card(類似memory card的東西)有損毀的情況,需要聯絡工程師進行處理。 4. **Filter Loading飆高** 放濾紙的小黑盒裡有片經常會掉落的O-ring,是靠近左上角的部分,重新放回去的方向是較厚的那一端要朝上 4. **Noise變高** 剛清完Cyclone會飆高(大概到0.030左右) 濾紙沒放好也會(大約0.010,或再低一些) 側邊濾紙沒鎖好 或太久沒換 不確定會不會有影響 5. **Filter Loading換完濾紙值就接近37 並且在37-45亂跳** 很可能是濾紙沒放好,換一張看有沒有降,不然就要聯絡工程師 工程師建議檢查流量 6. **Bypass flow warning** *The current bypass flow deviates more than 10% from the set point* 可能要注意濾紙有無進水 有時候換濾紙可以解決 7. **MC值為負 或值很低(0.1, 個位數或低的不可思議)** 到`Instrument Control`按`Set up` 將儀器讀值歸零後,按`Run`重跑一筆,持續觀察,高機率會在最近的時間再度發生(又發生就重複上述步驟) 8. **Pump vaccum is insufficient** 檢查TEOM pump壓力是否小於0.4 atm,若小於則要更換Pump 台製 $10000 原廠 $40000 可用3年 9. **Filter Loading升高很快** 可能是Bypass Water Cap Filter太髒 購買的話一個$4800(可多購買一個備品) 數據檢查 1.instrument conditions -> FDMS:dryer dew point正常要在-2以下 換dryer,關機,把前面電源關掉(往上切),把pump插頭拔掉 2.Noise要低於0.01,通常在0.00多 3.Frequency:250~300 Hz TEOM換濾紙校正流量時間/紀錄 2024/12/24(安裝PM1.0cyclone) 2025/1/13 2025/2/9 2025/3/3 warning:dryer dew point>0 (已聯絡工程師,目前正在等待dryer到貨) 2025/3/9 2025/4/20
