Before starting the pneumatic conveying equipment, it is necessary to inspect the equipment first, including whether the gear oil is full, whether all components are intact, the forward and reverse rotation of the Roots blower and rotary supply, and whether the water pipeline is smooth, etc.

啟動(dòng)時(shí)，應(yīng)先打開羅茨風(fēng)機(jī)，然后觀察鼓風(fēng)機(jī)出口壓力計(jì)的壓力，在管道通暢的情況下，壓力應(yīng)當(dāng)基本為零。然后打開一個(gè)旋轉(zhuǎn)供應(yīng)器，再慢慢打開上面的手動(dòng)板閥，板閥打開后，材料陷入旋轉(zhuǎn)供應(yīng)器，進(jìn)入輸水管道后，壓力計(jì)會(huì)發(fā)生波動(dòng)。根據(jù)材料的流動(dòng)性和壓力計(jì)的顯示，可以通過調(diào)整手動(dòng)閥門的敞開程度來(lái)調(diào)整下料量。隨時(shí)觀察壓力計(jì)的變化。

When starting, the Roots blower should be turned on first, and then the pressure gauge at the outlet of the blower should be observed. With the pipeline unobstructed, the pressure should be basically zero. Then open a rotary supply device, and slowly open the manual plate valve above. After the plate valve opens, the material falls into the rotary supply device, and when it enters the water pipeline, the pressure gauge will fluctuate. According to the fluidity of the material and the display of the pressure gauge, the cutting amount can be adjusted by adjusting the opening degree of the manual valve. Observe the changes in the pressure gauge at any time.

兩臺(tái)氣力輸送系統(tǒng)的運(yùn)輸線在一臺(tái)旋轉(zhuǎn)供給機(jī)材料輸送完成后，關(guān)閉一臺(tái)旋轉(zhuǎn)供給機(jī)，1-2分鐘后從管道輸送材料，然后打開二臺(tái)旋轉(zhuǎn)供給機(jī)依次運(yùn)行。

After the material transportation of two pneumatic conveying systems is completed by one rotary feeder, one rotary feeder is turned off, and after 1-2 minutes, the material is transported through the pipeline. Then, the two rotary feeders are turned on and run in sequence.

關(guān)閉設(shè)備的時(shí)候需要先關(guān)閉手動(dòng)板閥（設(shè)備暫時(shí)停止的話不必關(guān)閉手動(dòng)板閥），然后關(guān)閉旋轉(zhuǎn)供給器，觀察風(fēng)扇出口處的壓力計(jì)，直到壓力下降到攻關(guān)壓力（約1分鐘間隔）。

When shutting down the equipment, it is necessary to first close the manual plate valve (if the equipment is temporarily stopped, there is no need to close the manual plate valve), then turn off the rotary feeder and observe the pressure gauge at the fan outlet until the pressure drops to the breakthrough pressure (approximately 1 minute interval).

設(shè)備若是要停止3-4個(gè)小時(shí)及以上，就需要關(guān)閉手動(dòng)板閥，若是要停止1-2天及以上，需要在除塵結(jié)束后關(guān)閉手動(dòng)板閥。

If the equipment needs to stop for 3-4 hours or more, the manual plate valve needs to be closed. If it needs to stop for 1-2 days or more, the manual plate valve needs to be closed after the dust removal is completed.
