聯(lián)系我時，請告知來自 化工機械設(shè)備網(wǎng)化工反應(yīng)釜攪拌機目前的選型方法多數(shù)是根據(jù)實踐經(jīng)驗，選擇習(xí)慣應(yīng)用的槳型，再在常用范圍內(nèi)決定攪拌器的各種參數(shù)。也有通過小型試驗，取得數(shù)據(jù)，進行比擬放大的設(shè)計方法，因此反應(yīng)釜的選型不是的，前提是保證攪拌的效果。
化工反應(yīng)釜攪拌機目前的選型方法多數(shù)是根據(jù)實踐經(jīng)驗，選擇習(xí)慣應(yīng)用的槳型，再在常用范圍內(nèi)決定攪拌器的各種參數(shù)。也有通過小型試驗，取得數(shù)據(jù)，進行比擬放大的設(shè)計方法，因此反應(yīng)釜的選型不是的，前提是保證攪拌的效果。不論哪種做法，都離不開最初的根據(jù)攪拌目的來選擇反應(yīng)釜攪拌器類型這一步。所以一個完整拌目的來選擇反應(yīng)釜攪拌器類型這一步。所以一個完整的選型方案必須滿足經(jīng)濟與安全的要求，根據(jù)具體工況最后確定方案。
1、按反應(yīng)釜槳葉攪拌結(jié)構(gòu)分為平葉、斜(折)葉、彎葉、螺旋面葉式攪拌器。槳式、渦輪式攪拌器都有平葉和斜葉結(jié)構(gòu);推進式、螺桿式和螺帶式的槳葉為螺旋面葉結(jié)構(gòu)。根據(jù)安裝要求又可分為整體式和剖分式，便于把攪拌器直接固定在攪拌軸.上而不用拆除聯(lián)軸器等其他部件。
2、按反應(yīng)釜攪拌器的用途分為低黏流體用攪拌器、高黏流體用攪拌器。用于低黏流體的攪拌器有:推進式、槳式、三葉后完式等。用于高黏流體的攪拌器有:錨式、框式、鋸齒圓盤式、螺旋槳式、螺帶式等。
3、除此之外，化工反應(yīng)釜對于密封則也是相當(dāng)嚴(yán)格的，有常規(guī)單端面機封，雙端面機封，填料密封，根據(jù)不同的場合選擇合適的密封方式才是選型。
Most of the current selection methods of the reactor agitator are based on practical experience, selecting the paddle type that is customarily applied, and then determining various parameters of the agitator within the usual range. There are also design methods that use small experiments to obtain data and perform comparative amplification.Therefore, the selection of the reactor is not absolute, provided that the stirring effect is ensured. Either way, the initial step of selecting the type of reactor stirrer based on the purpose of mixing is indispensable.Therefore, a complete selection plan must meet economic and safety requirements, and finalize the best solution according to the specific working conditions.
1. According to the mixing structures of reactor blades, the mixers are divided into flat-blade, in dined (folded)-blade, curved-blade and helicoids-blade mixtures. Paddle and turbine mixers have flat-blade and inclined-blade structures. Impeller-type, crew-type and spiral ribbon-type blades are a helicoids-blade structure. According to installation requirements, mixers can be divided into an integral type and a split type so that it is easy to be directly fastened on the mixing shaft and doesn't need to disma ntle other parts in cludi ng couplings.
2. According to purposes of reactor mixers, they can be divided into mixers for low-viscosity fluids and mixers for high-viscosity fluids. The mixers for low-viscosity fluids in elude impeller-type, blade-type, open turbine-type, disc turbine-type, Brumagin-type, plate and frame blade-type and three-backward bent type mixers. The mixers for high-viscosity fluids in elude an chor-type, frame-type, jagged disc-type, propeller-type and spiral ribbon-type mixers.
3. In addition, chemical reactors have a strict requirement of sealing.There are general single-end face mechanical seals, double-end face mechanical seals and packing seals. It is the best model selection to choose a proper sealing method according to different scenarios.
