TDM1.2-50-300W1 在中央空調(diào)系統(tǒng)中,冷凍水泵和冷卻水泵的容量是根據(jù)建筑物最大設(shè)計(jì)熱負(fù)荷選定的,且留有一定的設(shè)計(jì)余量。在沒有使用調(diào)速的系統(tǒng)中,水泵一年四季在工頻狀態(tài)下全速運(yùn)行、只好采用節(jié)流或回流的方式來調(diào)節(jié)流量,產(chǎn)生大量的節(jié)流或回流損失,且對(duì)水泵電機(jī)而言,由于它是在工頻下全速運(yùn)行,因此造成了能量的大大浪費(fèi)。 由于季節(jié)的變化,外界溫度不同,使得中央空調(diào)的熱負(fù)荷在絕大部分時(shí)間里遠(yuǎn)比設(shè)計(jì)負(fù)荷低。也就是說,中央空調(diào)實(shí)際大部分時(shí)間運(yùn)行在低負(fù)荷狀態(tài)下。 恒壓供水變頻節(jié)能(變頻器在恒壓供水方面的應(yīng)用) 用戶用水的多少是經(jīng)常變動(dòng)的,因此供水不足或供水過剩的情況時(shí)有發(fā)生。而用水和供水之間的不平衡集中反映在供水的壓力上,即用水多而供水少,則壓力低;用水少而供水多,則壓力大。保持供水壓力的恒定,可使供水和TDM1.2-50-300W1用水之間保持平衡,即用水多時(shí)供水也多,用水少時(shí)供水也少,從而提高了供水的質(zhì)量。 TDM1.2-50-300W1恒壓供水系統(tǒng)對(duì)于某些工業(yè)或特殊用戶是非常重要的。例如在某些生產(chǎn)過程中,若自來水供水因故壓力不足或短時(shí)斷水,可能影響產(chǎn)品質(zhì)量,嚴(yán)重時(shí)使產(chǎn)品報(bào)廢和設(shè)備損壞。又如發(fā)生火災(zāi)時(shí),若供水壓力不足或或無水供應(yīng),不能迅速滅火,可能引起重大經(jīng)濟(jì)損失和人員傷亡。所以,某些用水區(qū)采用恒壓供水系統(tǒng),具有較大的經(jīng)濟(jì)和社會(huì)意義。 TDM1.2-50-300W1隨著電力技術(shù)的發(fā)展,變頻調(diào)速技術(shù)的日臻完善,以變頻調(diào)速為核心的智能供水控制系統(tǒng)取代了以往高位水箱和壓力罐等供水設(shè)備,起動(dòng)平穩(wěn),起動(dòng)電流可限制在額定電流以內(nèi),從而避免了起動(dòng)時(shí)對(duì)電網(wǎng)的沖擊;由于泵的平均轉(zhuǎn)速降低了,從而可延長泵和閥門等東西的使用壽命;可以消除起動(dòng)和停機(jī)時(shí)的水錘效應(yīng)。其穩(wěn)定安全的運(yùn)行性能、簡單方便的操作方式、以及齊全周到的功能,將使供水實(shí)現(xiàn)節(jié)水、節(jié)電、節(jié)省人力,最終達(dá)到高效率的運(yùn)行目的。 注塑機(jī)變頻節(jié)能(變頻器在注塑機(jī)中的應(yīng)用) TDM1.2-50-300W1注塑機(jī)是對(duì)各種注塑機(jī)料(例聚乙烯,聚丙烯等)成型加工的主要設(shè)備,通過對(duì)塑料顆粒在雙螺桿注塑機(jī)內(nèi)進(jìn)行多段溫度加熱
