德國FESTO費斯托電磁閥實用性怎么選型？
德國FESTO費斯托電磁閥適用性:管路中的流體必須和選用的電磁閥系列型號中標(biāo)定的介質(zhì)*電磁閥。流體的溫度必須小于選用電磁閥的標(biāo)定溫度。電磁閥允 許液體粘度一般在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時可選用先導(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；一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。流體清潔度不高時應(yīng)在電磁閥前安諾和閥門裝過濾器，一般電磁閥對介質(zhì)要求清潔度要好。注意流量 孔徑和接管口徑；電磁閥一般只有開關(guān)兩位控制；條件允許請安裝旁路管，便于維修；有水錘現(xiàn)象時要定制電磁閥的開閉時間調(diào)節(jié)。注意環(huán)境溫 度對電磁閥的影響。電源電流和消耗功率應(yīng)根據(jù)輸出容量選取，電源電壓一般允許10%左右，必須注意交流起動時VA值較高。德國FESTO費斯托電磁閥可靠性 電磁閥分為常閉和常開二種；一般選用常閉型，通電打開，斷電關(guān)閉；但在開啟時間很長關(guān)閉時很短時要選用常開型了。壽命試驗，工廠一般 屬于型式試驗項目，確切地說中國還沒有電磁閥的專業(yè)標(biāo)準(zhǔn)，因此選用電磁閥廠家時慎重。動作時間很短頻率較高時一般選取直動式，大口徑選 用快速系列。德國FESTO費斯托電磁閥安全性 一般電磁閥不防水，在條件不諾和閥門允許時請選用防水型，工廠可以定做。電磁閥的zui高標(biāo)定公稱壓力一定要超過管路內(nèi)的zui高壓力，否則 使用壽命會縮短或產(chǎn)生其它意外情況。有腐蝕性液體的應(yīng)選用全不銹鋼型，強(qiáng)腐蝕性流體宜選用塑料王電磁閥。爆炸性環(huán)境必須選用相應(yīng)的防爆 產(chǎn)品。費斯托FESTO電磁閥的經(jīng)濟(jì)性 ，有很多電磁閥可以通用，但在能滿足以上三點的基礎(chǔ)上應(yīng)選用的產(chǎn)品電磁閥在選擇時要考慮的因素。
德國FESTO費斯托電磁閥實用性怎么選型？
Applicability: Germany FESTO FESTO electromagnetic valve electromagnetic valve is used in the pipeline fluid must and electromagnetic valve series model calibration of the medium. Electromagnetic valve is used in the fluid temperature must be smaller than the calibration temperature. Solenoid valves allow 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, because this should pay attention to whether there is a pressure difference, install the check valve. When fluid cleanliness is not high, should general-secretary in front of the solenoid valve and valve installed filters, 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. Pay attention to the environment temperature influence on electromagnetic valve. Power supply current and power consumption should be selected according to the output capacity, power supply voltage generally allow 10%, must pay attention to communication when starting the VA value is higher. Germany FESTO FESTO reliability solenoid valve solenoid valve normally open and normally closed; General selection normally closed type, electric open, power is shut down; But when opened for a long time closed in very short time to choose the normally open type. Life test, the factory generally belongs to the type testing project, said China has not exactly professional standards of electromagnetic valve, so choose carefully when the solenoid valve manufacturer. Action time is very short at high frequency generally choose straight acting, choose with rapid series of large diameter. Germany FESTO FESTO safety solenoid valve General solenoid valve is not waterproof, when conditions and valve is not allowed, please choose waterproof model, the factory can be customized. Nominal pressure solenoid valve of the highest calibration must be more than the highest pressure in the pipeline, otherwise life will shorten or other unexpected circumstances. Corrosive liquid should be chosen in all stainless steel type, appropriate chooses the corrosive fluid plastic electromagnetic valve. Explosive environment must choose corresponding explosion-proof products. FESTO FESTO solenoid valve of the economy, there are a lot of solenoid valve can be common, but are able to meet the above three points should be chosen on the basis of the solenoid valve in the most economical product factor to consider when the choice.
