除塵器配件BOSCH電磁閥的適用性資料有哪些？
BOSCH電磁閥的工作，用手去觸摸電磁閥閥體，假如閥體溫度不是很高的而且閥里面有氣流聲，則只能說明電磁閥關(guān)閉的不是很嚴(yán)故障原因也有可能的原因是由于閥體里面存在臟物、閥座或閥針受損拉毛、彈簧力過小等故障處理辦法應(yīng)該操作為清除閥體里面的臟物、研磨閥座和閥針、調(diào)整或更換彈簧。
BOSCH電磁閥堵塞
BOSCH電磁閥無法正常工作，如果是冷藏箱電磁閥，則電磁閥表面可能會有低溫甚結(jié)霜的現(xiàn)象出現(xiàn)故障原因直流電磁閥體里面內(nèi)部有可能是雜物堵塞故障處理辦法拆開電磁閥并清除內(nèi)部雜物
BOSCH電磁閥通電時(shí)，出現(xiàn)“嗒嗒"跳動聲
BOSCH電磁閥通電時(shí)，出現(xiàn)“嗒嗒"跳動聲故障原因有可能電源電壓很低、由于電磁閥的進(jìn)出口壓力差很高使銜鐵吸不上、系統(tǒng)中里面也有空氣、電磁閥安裝方向與制冷劑流動方向又是相反、銜鐵被卡或損壞、電磁閥短路磁環(huán)斷裂就會導(dǎo)致開路。
除塵器配件BOSCH電磁閥的適用性 管路中的流體必須和選用的BOSCH電磁閥系列型號中標(biāo)定的介質(zhì)致。流體的溫度必須小于選用電磁閥的標(biāo)定溫度。電磁閥允許液體粘度般在20cst以下，大于20cst應(yīng)注明。工作壓差，管路zui高壓差在小于0.04mpa時(shí)應(yīng)選用如zs,2w,zqdf,zcm系列等直動式和分步直動式；zui低工作壓差大于0.04mpa時(shí)可選用導(dǎo)式（壓差式）電磁閥；zui高工作壓差應(yīng)小于電磁閥的zui大標(biāo)定壓力；般電磁閥都是單向工作，因此要注意是否有反壓差，如有安裝止回閥。流體清潔度不高時(shí)應(yīng)在電磁閥前安裝過濾器，般電磁閥對介質(zhì)要求清潔度要好。注意流量孔徑和接管口徑；電磁閥般只有開關(guān)兩位控制；條件允許請安裝旁路管，便于維修；有水錘現(xiàn)象時(shí)要定制電磁閥的開閉時(shí)間調(diào)節(jié)。除塵器配件電磁閥的適用性。
以下是參考譯文：
The applicability of the dust collector accessories electromagnetic valve fluid pipeline must be the solenoid valve series models and choose calibration medium. Electromagnetic valve is used in the fluid temperature must be smaller than the calibration temperature. Solenoid valve to allow the liquid viscosity, generally under 20 CST, more than 20 CST shall be indicated. Working pressure difference, line the high-pressure difference should be chosen as zs when less than 0.04 mpa, 2 w, ZQDF, ZCM series and type of moving step by step straight acting; When the minimum working pressure difference is greater than 0.04 mpa can choose guiding type (differential) electromagnetic valve; Maximum working pressure difference should be less than the biggest calibration pressure solenoid valve; General solenoid valve is a one-way work, so should pay attention to whether there is a pressure difference, install the check valve. Fluid cleanliness is not high when the filters should be installed in front of the solenoid valve, general solenoid valve is better claim to medium cleanness. Pay attention to the traffic pore size and diameter; Two solenoid valve usually only switch control; Conditions permit, please install bypass pipe, easy maintenance; When there is water hammer to customize solenoid valve opening and closing time to adjust
