MD 泵應(yīng)該為空，壓力為零。沒(méi)有控制空氣壓力時(shí)，閥門(mén)不會(huì)密封。 The start / stop / purge switch at the HMI is set to “START” or “PURGE”. 主電控屏幕上的啟動(dòng) /停止 /吹掃開(kāi)關(guān)置于“啟動(dòng)”或“吹掃”位置。 Conveying pressure is barg (PT25). 輸送壓力 barg (PT25)。（詳見(jiàn)輸送管路控制一節(jié)） Space is available in the target reception silo (As defined in the section on conveying route control). 目標(biāo)終端灰?guī)炜捎?。（?jiàn)報(bào)警條件匯總） Client interlock is healthy (if available) 客戶(hù)連鎖正常（如果可用）。 Providing the above conditions are true a conveying cycle will be initiated and will proceed as follows: 如果上述條件滿(mǎn)足，輸送循環(huán)將啟動(dòng)并按如下步驟運(yùn)行： Step 1第一步 The master vessel inlet/vent Dome Valves will be opened by energising solenoid (EV01). The slave 1 inlet/vent Dome Valve open delay timer (0 second), the short fill timer (600 seconds), and cycle watchdog timer (945 seconds) will be started. Material will fall under gravity into the master DensPhase MDPump. 主泵進(jìn)口閥、排氣閥由相應(yīng)的電磁閥 (EV01)得電開(kāi)啟， 1號(hào)付泵進(jìn)口閥、排氣閥開(kāi)啟延遲定時(shí)器（ 0秒）、短填充定時(shí)器（ 600秒）、循環(huán)監(jiān)視定時(shí)器（ 945秒）打開(kāi)。 Step 2第二步 CBM Project No/Issue: C06151/1 Date: January 2020 Section 2 Page 9 of 62 Sheet Rev No. 00 When the slave 1 inlet/vent Dome Valve open delay timer has expired the slave vessel 1 inlet/vent Dome Valves will be opened by energising the solenoid (EV01) and the slave 2 inlet/vent Dome Valve open delay timer (0 second) will be started. Material will fall under gravity into the slave 1 DensPhase MDPump. 當(dāng) 1號(hào)付泵進(jìn)口閥、排氣閥開(kāi)啟延遲定時(shí)器完成， 1號(hào)付泵進(jìn)口閥、排氣閥由電磁閥 (EV01)得電開(kāi)啟。物料在重力作用下落入 1號(hào)付 MD 泵 。出口泵進(jìn)口閥、排氣閥開(kāi)啟延遲定時(shí)器（ 0秒）打開(kāi)。 Step 4第四步 When the outlet vessel inlet/vent Dome Valve open delay timer has expired the outlet vessel inlet/vent Dome Valves will be opened by energising the solenoid (EV01) and the inline Dome Valve close delay timer (1 second) will be started.

Conveying air will be introduced in to the conveying line by piloting off from the master fluidising air. Simultaneously the Outlet vessel fluidisation delay timer (0 seconds) and this systems conveying start offset timer (20 seconds) will be started. 當(dāng)所有的進(jìn)口閥 (PS01)和排氣閥 (PS05)關(guān)閉并密封，管路圓頂閥 (ZSO03)已打開(kāi)，所有的輸送啟動(dòng)偏移定時(shí)器已到時(shí)，主泵流化空氣閥 (EV15)和混氣閥(EV14)分別由電磁閥得電打開(kāi)。同時(shí)，出口泵流化延遲定時(shí)器（ 0秒）和系統(tǒng)輸送啟動(dòng)偏移定時(shí)器（ 20秒）打開(kāi)。 Step 9第九步 When the Outlet vessel fluidisation delay timer has expired the Outlet MDPump fluidising valve (PV15) will be opened by energising solenoid (EV15).

The fluidisation delay timers will be reset and the conveying cycle will restart from Step 8 once the pressure has fallen below the barg. 說(shuō)明：如果輸送循環(huán)進(jìn)行到第八步至第 13 步，輸送壓力 (PT25)上升至 以上，混氣閥 (PV14)和流化閥 (PV15)關(guān)閉。 Step 10第十步 When the last Slave vessel fluidisation delay timer has expired the last Slave MDPump fluidising valve (PV15) will be opened by energising solenoid (EV15).
