差壓表安裝 Differential pressure gauges dimensions
（一）          后背板安裝 Back mounting
Note: 1. back mounting fit for plate mounting
注：1、后背板只適合平面安裝（如儀表板、機器外表平面等）；(instrument plate, and outer surface etc)
2、注意平面要堅固，使差壓表安裝后牢固，不會發生掉落；    2.Make sure the plane and mount the
3、 特殊后背板可按客戶要求出圖加工或照來樣加工。         differential gauge are tight, which will not fall off.
 
（二）          固定支架安裝 Steady rest mounting
 
注：1、固定支架安裝只適用于管道安裝（橫向或豎向； Note: 1. Steady rest mounting is suitable for pipe
2、注意管道的外徑不能大于60mm；                              (horizontal or vertical)
3、 儀表可以裝到支架上方或下方，方便用戶自由選擇。      2.Outer diameter of pipe cannot over 60mm

三閥組的安裝、拆卸及使用方法
Three Valves mounting, disassembly and method of application
安裝 Mounting
1. 正常使用差壓表必須配三閥組或五閥組以保護差壓表正常工作。
2. 差壓表和三閥組用兩個索母緊固。索母和差壓表接頭密封面應加四氟墊片。
3. 裝有三閥組的差壓表在使用前必須把中間閥門打開，并把正壓閥門和負壓閥門打開。（當P+ 和P- 任意的壓力先進入時，中間閥門能起到平衡差壓表兩腔體內的壓力的作用，以免打壞差壓表。）
4. 當P+、P- 的壓力正常進入三閥組后，再關閉中間閥門使差壓表正常工作。如差壓表表針有輕微離零屬正常，只需把表針調到零位即可（注意必須用肥皂水檢驗所有密封口是否泄露，如有泄露必須緊固。）
5. 差壓表有后背板式安裝（如圖）和立管固定方法。（管卡子卡到管子上）。
1. Use differential gauge must fit out three valves in order o insure it’s normalworking.
2. The differential gauge and there valves are connected by two uts tightly, nut and socket are with PTFEspacer.
3. Open the middle valve, negative pressure valve and positive ressure valve before use the differential gauge, when either of P- or P+ input, the middle valve can have equilibrium activity, and avoid to damage the gauge.
4. When P- and P+ normal input the three valves, the close the middle valve, to make the gauge works right. If the gauge’s pointer is not at zero, please adjust itto zero (note must use soap water to inspect the seal, if has leak, please tight.)
5. The differential pressure gauge has back plate mounting (see the chart) and tandpipe fixed (the pipe with clamp).
 
拆卸 Disassembly
1. 首先打開三閥組的中間閥門。并打開正壓和負壓閥門（正壓負壓閥門原始為打開）
2. 關閉總進氣的兩個閥門。（在設備的主管道上）
3. 拆下更換儀表（卸兩個索母）注意用扳子卡住差壓表的接頭，只拆三閥組上的上索母。先松開一點放空壓力，再把卡到管子上的卡子螺母松掉，并把卡子拿下。
4. 再把三閥組上的兩個索母慢慢松開把差壓表取下。（注意一定要兩個索母同時松）
5. 把新表裝上的方法同上面安裝方法換上兩個新的四氟墊 （確保不漏）
6. 把卡子卡好
7. 先開總開關（兩個），再關上差壓表三閥組中間的閥門（新接口用肥皂水試漏）。
8. 兩分鐘后把差壓表表針調到零位。（如沒有輕微離零不用調整）
1. Open the middle valve, negative pressure valve and positive pressure valve(negative pressure valve and positive pressure valve original state is open).
2. Close these two input valves (on the main pipe of equipment).
3. Discharge instrument (discharge two nuts), use spanner lock the socket of gauge, and just discharge the nuts on three valves.Discharge pressure, then put off the nuts and clamp.
4. Screw down the two nuts and take down the differential pressure gauge (note screw down these two nuts together)
5. Then install the new gauge (same as mounting method), change two spacers to ensure it will not leak.
6. Fix the clamp.
7. Open main switch (two), then close the middle valve. (use soap water to inspect leak)
8. Two minutes later, set the pointer at zero (if it does not out off zero, you needn’t to adjust).
注：在裝表或卸表時，必須保證中間閥門和P+、P- 兩個閥門全部開啟，以確保儀表能正常使用。
