產(chǎn)品詳情
不要采用不同金屬的導(dǎo)線相互連接。屏蔽管(層)應(yīng)可靠接地,并保證整個(gè)長(zhǎng)度上連續(xù)可靠接地。信號(hào)電路中要使用雙絞線屏蔽電纜。屏蔽層接地點(diǎn)盡量遠(yuǎn)離變頻器,并與變頻器接地點(diǎn)分開。磁環(huán)可以在變頻器輸入電源線和輸出線上使用,具體方法為:輸入線一起朝同一方向繞4圈,而輸出線朝同一方向繞3圈即可。繞線時(shí)需注意,盡量將磁環(huán)靠近變頻器。一般對(duì)被干擾設(shè)備儀器,均可采取屏蔽及其它抗干擾措施。、想提高原有輸送帶的速度,以8Hz運(yùn)轉(zhuǎn),變頻器的容量該怎樣選擇?輸送帶消耗的功率與轉(zhuǎn)速成正比,因此若想以8HZ運(yùn)行,變頻器和電機(jī)的功率都要按照比例增加為8HZ/5HZ,即提高6%容量。、采用PWM和VVC+的區(qū)別是什么?在VVC中,控制電路用一個(gè)數(shù)學(xué)模型來(lái)計(jì)算電機(jī)負(fù)載變化時(shí)的佳的電機(jī)勵(lì)磁,并對(duì)負(fù)載加以補(bǔ)償。此外集成于ASIC電路上的同步6PWM方法決定了逆變器半導(dǎo)體器件(IGBTS)的佳開關(guān)時(shí)間。
FKN系列逆流開式冷卻塔FKN系列--逆流開式冷卻塔相對(duì)于FBN系列閉式冷卻塔具有以下缺點(diǎn):占地較大,噪音較大(閉塔采用低噪音風(fēng)機(jī),噪音少);補(bǔ)水量大(夏天時(shí)每天需補(bǔ)水量為冷卻塔總水量的1/3);大量的水汽蒸發(fā),帶走好的水分子,降低水質(zhì);容易進(jìn)雜質(zhì)、雨水等,易生水垢,且難以清理;冷卻效果相對(duì)不好(夏天能達(dá)到41℃,閉塔能保證332℃)FKN系列--逆流開式冷卻塔相對(duì)于FBN系列逆流閉式冷卻塔其工作原理基本相似,區(qū)別在于FKN系列開式冷卻塔內(nèi)無(wú)冷卻盤管,這對(duì)于開塔在各個(gè)行業(yè)的使用受到了極大的限制;但開塔相對(duì)于閉塔投資成本較小。
TIMKEN軸承TIMKEN分離型軸承的安裝由于內(nèi)圈與外圈可方便地分別裝到軸或軸承座上.此時(shí)應(yīng)引起注意的是將是將已經(jīng)裝好內(nèi)圈的軸插入已裝好外圈的軸承箱時(shí),盡量使其保持同心,以防擦傷滾動(dòng)體和滾道。對(duì)TIMKEN軸承內(nèi)圈與軸時(shí)緊配合、外圈軸承座孔是較松配合的非分離型軸承進(jìn)行安裝時(shí),分離型軸承的安裝由于內(nèi)圈與外圈可方便地分別裝到軸或軸承座上.此時(shí)應(yīng)引起注意的是將是將已經(jīng)裝好內(nèi)圈的軸插入已裝好外圈的軸承箱時(shí),盡量使其保持同心,以防擦傷滾動(dòng)體和滾道。
PPC氣箱脈沖除塵器由殼體、灰斗、排灰裝置、支架和脈沖清灰系統(tǒng)等各部分組成。當(dāng)含塵氣體從進(jìn)風(fēng)口進(jìn)入除塵器后,首先碰到進(jìn)風(fēng)口中間的斜隔板,氣流便轉(zhuǎn)向流入灰斗,同時(shí)氣流速度變慢,由于慣性作用,使氣體中粗顆粒粉塵直接落入灰斗,起到預(yù)收塵的作用,進(jìn)入灰斗的氣流后折而向上通過內(nèi)部裝有金屬骨架的濾袋,粉塵被捕集在濾袋的外表面,凈化后的氣體進(jìn)入濾袋室上部的清潔室,匯集到出風(fēng)管排出。PPC氣箱脈沖除塵器可廣泛用于水泥廠的破碎、包裝、庫(kù)頂、熟料冷卻機(jī)和各種磨機(jī)等除塵系統(tǒng)、如用于煤磨除塵、要增設(shè)防燃防爆措施,除塵器結(jié)構(gòu)也相應(yīng)的改變,還適合含塵濃度特高的氣體的收塵,如帶O-Sep洗粉機(jī)的粉磨系統(tǒng),氣體含塵濃度高達(dá)1G/M3以上,采用本系列除塵器收塵,可不設(shè)置旋風(fēng)除塵器作一級(jí)收塵。
