答：羅茨風(fēng)機會在管道內(nèi)形成負(fù)壓嗎？是的，能夠在入口造成負(fù)壓現(xiàn)象的羅茨鼓風(fēng)機多為壓力過高或超負(fù)載運轉(zhuǎn)造成的！高壓羅茨風(fēng)機出現(xiàn)負(fù)壓時，應(yīng)針對其原因分別采取措施進行處理。首先應(yīng)適當(dāng)減少氣量，以免高壓風(fēng)機機管道入口抽成負(fù)壓，造成惡性事故，然后查明原因，分別處理，待處理正常后再加負(fù)荷。將氣量減少至低程度，必然時緊急停車，待煤氣系統(tǒng)處理正常，氣框有上升趨勢時，交換系統(tǒng)應(yīng)爭取時間開車。下面羅列一下羅茨鼓風(fēng)機入口產(chǎn)生負(fù)壓的原因，幫助各位老板解決并預(yù)防該問題的存在與產(chǎn)生！

　　羅茨風(fēng)機入口產(chǎn)生負(fù)壓的原因

　　1.氣框出口水封積水過高，氣體被水封住;

　　2.氣框出口閥未打開或閥芯脫落;

　　3.氣框出口管嚴(yán)重積灰并落下，使管道被堵塞;

　　4.冬天氣溫突然降低，氣框出口管內(nèi)冷凝水結(jié)冰;

　　5.由于煤氣爐造氣不佳或設(shè)備故障如安全擋板不開，無風(fēng)入爐;

　　6.氣框進口水封積水或氣體倒流等引起氣框壓力急劇下降。

此外，羅茨風(fēng)機超載也是入口產(chǎn)生負(fù)壓的原因之一。因此，建議各位購買羅茨風(fēng)機時根據(jù)自己的需求，購買相應(yīng)功率與壓力的羅茨鼓風(fēng)機！下面簡單總結(jié)一下超載的原因分享給大家！

　　可能導(dǎo)致高壓羅茨風(fēng)機電動機超載原因

　　一.系統(tǒng)壓力變化所導(dǎo)致的電動機超載

　　進口過濾器堵塞或者其它原因?qū)е碌脑O(shè)備壓力增高，從而在出口壓力不變情況下增高升壓，對設(shè)備形成負(fù)壓導(dǎo)致電動機超載。

　　高壓羅茨風(fēng)機設(shè)備的出口系統(tǒng)壓力有所增加導(dǎo)致電動機超載運行，這種情況需要對設(shè)備出風(fēng)口系統(tǒng)進行檢查后徹底清除清理。

　　二.設(shè)備零部件不正常所引起的電動機超載

　　1.設(shè)備齒輪出現(xiàn)損壞;

　　2.設(shè)備軸承損壞，需要對其進行更換;

　　3.設(shè)備靜動件出現(xiàn)摩擦情況增加電動機的負(fù)載，需要對其設(shè)備間隙進行調(diào)整改善這種情況。

　　A: Roots blowers that can cause negative pressure at the inlet are mostly caused by excessive pressure or overload operation! When the high-pressure roots blower has negative pressure, measures should be taken to deal with the causes. First of all, the air volume should be appropriately reduced to avoid negative pressure at the inlet of the high-pressure fan pipe, resulting in a malignant accident, and then find out the causes, deal with them separately, and add load after the treatment is normal. Reduce the gas volume to a low level, and when necessary, emergency shutdown. When the gas system is handled normally and the gas frame has an upward trend, the exchange system should strive for time to start. The following is a list of the causes of negative pressure at the inlet of Roots blower to help bosses solve and prevent the existence and occurrence of this problem!

　　Causes of negative pressure at Roots blower inlet

　　1. The water in the water seal at the outlet of the gas frame is too high, and the gas is sealed by water;

　　2. The air frame outlet valve is not opened or the valve core falls off;

　　3. The outlet pipe of the air frame is seriously dusty and falls, causing the pipe to be blocked;

　　4. The temperature suddenly drops in winter, and the condensate in the outlet pipe of the air frame freezes;

　　5. Due to poor gas production of the gas furnace or equipment failure, if the safety baffle does not open, there is no air entering the furnace;

　　6. Water accumulation or gas backflow at the inlet of the gas frame cause the gas frame pressure to drop sharply.

　　In addition, the overload of Roots blower is also one of the reasons for the negative pressure at the inlet. Therefore, it is recommended that you buy roots blowers with corresponding power and pressure according to your own needs! The following is a brief summary of the reasons for overloading to share with you!

　　Possible causes of overload of high voltage roots blower motor

　　I Motor overload caused by system pressure change

　　The pressure of the equipment increases due to the blockage of the inlet filter or other reasons, which increases the pressure rise when the outlet pressure remains unchanged, forming a negative pressure on the equipment and causing the motor overload.

　　The pressure of the outlet system of the high-pressure roots blower equipment has increased, resulting in the overload operation of the motor. This situation needs to be thoroughly cleaned after the inspection of the air outlet system of the equipment.

　　II Motor overload caused by abnormal equipment parts

　　1. The equipment gear is damaged;

　　2. The equipment bearing is damaged and needs to be replaced;

　　3. The friction of the static and moving parts of the equipment increases the load of the motor, and the equipment clearance needs to be adjusted to improve this situation.
