1.風(fēng)量平衡的影響因素
1 influencing factors of air volume balance
潔凈廠房設(shè)計(jì)施工的風(fēng)量平衡是潔凈室維持正壓值和潔凈度的保證。無(wú)塵車間出現(xiàn)風(fēng)量不平衡的主要因數(shù)有：
The air flow balance in the design and construction of the clean room is the guarantee of maintaining the positive pressure value and cleanliness of the clean room. The main factor of the air flow in the dust free workshop is:
（1）初、中、高效過(guò)濾器隨著使用時(shí)間的增加。阻力也會(huì)增加，造成送風(fēng)量減少，室內(nèi)正壓值發(fā)生變化。
(1) at the beginning, middle and high efficiency filters increase with time. Resistance will also increase, resulting in reduced air supply, indoor positive pressure value changes.
（2）生產(chǎn)工藝發(fā)生變化，排風(fēng)量增加或減少造成無(wú)塵車間室內(nèi)正壓值的減少或增加。
(2) changes in production processes, increase or decrease in the amount of exhaust air or decrease or increase the positive pressure value of the dust free workshop.
（3）隨著無(wú)塵車間投入使用時(shí)間的增加，圍護(hù)結(jié)構(gòu)和門窗出現(xiàn)漏風(fēng)現(xiàn)象，造成無(wú)塵車間內(nèi)正壓值發(fā)生變化。
(3) with the dust-free workshop put into use time increased, the envelope and the doors and windows appear leakage phenomenon, cause dust-free workshop in positive pressure value changes.
（4）管理不善，人員和設(shè)備的出入口、門或氣閘室關(guān)閉不嚴(yán)，造成無(wú)塵車間內(nèi)正壓發(fā)生變化。
(4) mismanagement, personnel and equipment import and export, door, or airlock closes lax, resulting in dust-free workshop in positive pressure change.
（5）送風(fēng)機(jī)皮帶松動(dòng)或轉(zhuǎn)速降低造成送風(fēng)量不足。
(5) the belt is loose or the speed of the fan is reduced and the air supply is reduced.
（6）個(gè)別FFU的風(fēng)機(jī)或電機(jī)發(fā)生故障，停止運(yùn)行造成循環(huán)風(fēng)量不足。
(6) the FFU of the wind turbine or motor failure, to stop the operation of the circulation caused by insufficient.
2.解決風(fēng)量不平衡的措施
2 to solve the air flow imbalance measures
（1）潔凈廠房設(shè)計(jì)施工 http://www.jnjkjh.com/ 選用過(guò)濾器風(fēng)量時(shí)選用過(guò)濾器額定風(fēng)量的75%~80%，隨著過(guò)濾器阻力的增加，逐步加大送風(fēng)閥門的開(kāi)度，直到過(guò)濾器達(dá)到終阻力時(shí)更換過(guò)濾器。
(1) clean plant design and construction of the selection of the filter air filter rated air 75%~80%, with the increase in the filter resistance, and gradually increase the opening of the wind valve, until the filter to reach the final resistance when the replacement filter.
（2）空調(diào)箱的送風(fēng)機(jī)或FFU的送風(fēng)機(jī)采用變頻電機(jī)，初運(yùn)行時(shí)將送風(fēng)機(jī)或FFU的電機(jī)運(yùn)行頻率調(diào)低，隨著運(yùn)行時(shí)間的增加，過(guò)濾器阻力也增加時(shí)逐步調(diào)高電機(jī)頻率以保證達(dá)到設(shè)計(jì)送風(fēng)量。
(2) the air conditioner or FFU of the air conditioner adopts frequency conversion motor, and the motor operating frequency of the blower or FFU is reduced, with the increase of running time, the frequency of the filter increases with the increase of the frequency of the motor.
（3）當(dāng)工藝排風(fēng)量發(fā)生變化時(shí)，調(diào)整系統(tǒng)的新風(fēng)量，這就必須把新風(fēng)系統(tǒng)設(shè)計(jì)成變風(fēng)量系統(tǒng)以求得排風(fēng)和新風(fēng)達(dá)到平衡，否則當(dāng)工藝發(fā)生變化時(shí)排風(fēng)量不能增加或減少。
(3) when the process is changed, the fresh air volume of the system should be designed as a variable air volume system to achieve the balance between the wind and the wind.
（4）加強(qiáng)潔凈空調(diào)系統(tǒng)的運(yùn)行管理，提高管理人員的素質(zhì)。制定嚴(yán)密的管理制度。
(4) strengthen the operation management of the clean air conditioning system, improve the quality of the management personnel. Formulate strict management system.
（5）潔凈廠房設(shè)計(jì)施工應(yīng)配備壓差表測(cè)試儀器，當(dāng)正壓值發(fā)生變化時(shí)及時(shí)報(bào)警，采取相應(yīng)措施保證無(wú)塵車間的正壓值。
(5) the design and construction of clean plant should be equipped with a pressure difference meter test instrument, when the positive pressure value changes, the timely warning, to take corresponding measures to ensure that the normal pressure value of the workshop.
