FESTO電磁閥在選擇時(shí)要考慮的因素資料有哪些
一：FESTO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(hào)中標(biāo)定的介質(zhì)一致電磁閥。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，管路壓差在小于0.04MPa時(shí)應(yīng)選用如ZS,2W,ZQDF,ZCM系列等直動(dòng)式和分步直動(dòng) 式；低工作壓差大于0.04MPa時(shí)可選用先導(dǎo)式（壓差式）電磁閥；工作壓差應(yīng)小于電磁閥的標(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(shí)應(yīng)在電磁閥前安諾和閥門裝過(guò)濾器，一般電磁閥對(duì)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(kāi)關(guān)兩位控制；條件允許請(qǐng)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(kāi)閉時(shí)間調(diào)節(jié)。注意環(huán)境溫度對(duì)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(dòng)時(shí)VA值較高。
二、FESTO電磁閥可靠性電磁閥分為常閉和常開(kāi)二種；一般選用常閉型，通電打開(kāi)，斷電關(guān)閉；但在開(kāi)啟時(shí)間很長(zhǎng)關(guān)閉時(shí)很短時(shí)要選用常開(kāi)型了。壽命試驗(yàn)，工廠一般屬于型式試驗(yàn)項(xiàng)目，確切地說(shuō)還沒(méi)有電磁閥的專業(yè)標(biāo)準(zhǔn)，因此選用電磁閥時(shí)慎重。動(dòng)作時(shí)間很短頻率較高時(shí)一般選取直動(dòng)式，大口徑選用快速系列。
三、FESTO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(shí)請(qǐng)選用防水型，工廠可以定做。電磁閥的標(biāo)定公稱壓力一定要超過(guò)管路內(nèi)的壓力，否則使用壽命會(huì)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。
四、經(jīng)濟(jì)性　　有很多電磁閥可以通用，但在能滿足以上三點(diǎn)的基礎(chǔ)上應(yīng)選用經(jīng)濟(jì)的產(chǎn)品電磁閥在選擇時(shí)要考慮的因素。
譯文：A: applicability fluid pipe must be consistent in the medium of electromagnetic valve calibration and the electromagnetic valve series models in the. The temperature of the fluid must be less than the calibration temperature of the solenoid valve. Solenoid valve to allow the liquid viscosity generally below 20CST, more than 20CST should be specified. Working pressure, the maximum pressure in the pipeline is less than 0.04MPa should be used such as ZS, 2W, ZQDF, ZCM series direct drive type and step and direct action; minimum working pressure is more than 0.04MPa can be selected for the pilot (differential) electromagnetic valve; the maximum working pressure should be less than the maximum nominal pressure solenoid valve; general solenoid valve is a one-way operation, so should pay attention to whether the anti pressure, if installed check valve. Fluid cleanliness is not high when filter before the solenoid valve anno and valve, the general cleanliness requirements solenoid valve on the media. Note flow pore diameter and over; solenoid valve generally only two control switches; conditions permit to install a bypass pipe, easy to repair; a water hammer phenomenon to customize the opening and closing time adjustment of electromagnetic valve. Pay attention to the influence of environmental temperature on the solenoid valve. Power supply current and power consumption should be selected according to the output capacity, power supply voltage generally allows ± 10%, attention must be paid to the exchange value of the higher VA start. Two, reliability Electromagnetic valve is normally closed and normally open two; general selection of normally closed, open, power off; but in the open for a long time close very short to use normal open type. Life test, factory type test items are generally, exactly professional standard Chinese no electromagnetic valve, so use caution when solenoid valve manufacturers. Action time is very short high frequency selecting direct acting, rapid series of large caliber selection. Three, security General solenoid valve is not waterproof, in the condition of no and valve allows to use water when you type, the factory can be customized. The maximum calibration nominal pressure solenoid valve must be more than the maximum pressure within the pipe, otherwise life will be shortened or have other unforeseen circumstances. Corrosive liquids should be used all stainless steel type, strong corrosive fluids should use plastic Wang solenoid valve. Explosive environment must use the appropriate explosion-proof products. Four, economic There are a lot of solenoid valve can be generic, but in the foundation to meet the above three points should choose the most economical products..
