產(chǎn)品概述：;水力噴射器是一種具有抽真空、冷凝、排水等三種有效能的機(jī)械裝置。它是利用一定壓力的水流通過對(duì)稱均布成一頓斜度的噴咀噴出,聚合在一個(gè)焦點(diǎn)上。由于噴射水流速很高,于是周圍形成負(fù)壓使器室內(nèi)產(chǎn)生真空、另外由于二次蒸汽與噴射水流直接接觸,進(jìn)行熱交換,絕大部份的蒸汽冷凝成水,少量未被冷凝的蒸汽與不凝結(jié)的氣體亦由于與高速噴射的水流互相摩擦,混合與擠壓,通過擴(kuò)壓管被排除,使器室內(nèi)形成更高的真空。水力噴射器應(yīng)用極為廣泛,主要用于真空與蒸發(fā)系統(tǒng),進(jìn)行真空抽水、真空蒸發(fā)、真空過濾、真空結(jié)晶、干燥、脫臭等工藝,是制糖、制藥、化工、食品、制鹽、味精、牛奶、發(fā)酵以及一些輕工、*門廣泛需求的設(shè)備。但目前生產(chǎn)的制造廠較少,品種亦不齊,為此,我單位近年來不斷改進(jìn)設(shè)計(jì)。采用多嘖咀與汽環(huán)(導(dǎo)向盤)等結(jié)構(gòu),以及用多級(jí)泵進(jìn)水,低位安裝,只需安裝高度4.5米,完善與提高了其工作性能,具有一定的*性、是真空冷凝設(shè)備的一種革新。 the product summary : the waterpower injector is one kind possesses lashes the vacuum , condensation and draining off water etc three kinds effectively can the mechanical device . it is the utilization certainly rivers of pressure by way of symmetrical all injection nozzles of cloth degree of inclination one-tenth spurts , gets together in a focal point . because the fact that the rivers speed is the injection very high , so the negative pressure of formation in vicinity making the ware indoor given rise to the vacuum and different because two steam and injection rivers physical contact , carrying on the heat exchange , the steam of desperate greater part sake condenses into water , and a few steam and gas that does not congeal that is not condensed also because with the rivers of high velocity injection rubs mutually , mix and extrudings , by way of expand presss pipe is got rid of , makes the higher vacuum of formation of ware indoor . the waterpower injector application is very extensive , technology such as is chiefly used vacuum and evaporation system , and is in progress that the vacuum draws water and filter in vacuum evaporation and vacuum , the crystal in vacuum , dry and is shed smelly etc , and is refining sugar and pharmacy , chemical industry , foodstuff , system salt , monosodium glutamate , milk , ferments as well as some light industrys and the ministry of national defence extensively the equipment of requirement . but the manufacturing factory of production at present waterpower injector lacks , and the breed is also not neat , and my unit constantly improves the design in recent years therefor . many zes chews and vapour ring ( direction dish ) waiting structure is used , as well as intakes with the many stages pump , the low order is installed , only needs to install 4.5 meters of height , and it is perfect in having raised his work capability , possessing advanced nature certainly and is one kind of innovate of vacuum condensation equipment 結(jié)構(gòu)特點(diǎn)由器體、器蓋、噴咀、噴咀座板、導(dǎo)向盤、擴(kuò)壓管及單向閥等部件組成,噴咀用不銹鋼制造,噴咀座板由優(yōu)質(zhì)鋼加工,其余零件則系鑄鐵鑄造。噴咀采用多噴咀的結(jié)構(gòu)形式,以便得到較大的水一汽接觸面積,有利于熱交換的進(jìn)行,獲得較好的真空效果。噴咀座板加工精密,精度較高,以便噴射水流準(zhǔn)確地聚集在同一的焦點(diǎn)。導(dǎo)向盤用于減慢蒸汽(或空氣)的流速,使蒸氣均勻地導(dǎo)入器室以免噴射水流偏斜,降低抽射效能。整個(gè)裝置結(jié)構(gòu)緊湊精密,強(qiáng)度亦較高,用于真空蒸發(fā)系統(tǒng)中,由于能把冷凝器的冷凝作用與真空泵的抽氣作用合并在一個(gè)設(shè)備中同時(shí)完成,大大地簡(jiǎn)化了工藝流程,比之原來用真空泵與舊式冷凝器的裝置,可以節(jié)省去真空泵、冷凝器,分水器等設(shè)備,并且還有下列優(yōu)點(diǎn):(1)體積小、重量輕、結(jié)構(gòu)緊湊。而效能又比較高,耗電量低于真空泵系統(tǒng),投資省。(2)操作簡(jiǎn)單維修方便,不用專職人員管理,由于無(wú)機(jī)械傳動(dòng)部份,所以噪聲低,不需消耗潤(rùn)滑油。(3)可以室外底位安裝,占地面積少,可以節(jié)省廠房建筑面積與安裝費(fèi)用 the structure characteristic : parts such as the waterpower injector by the ware aspect and ware gai injection nozzle , injection nozzle seat board , direction dish and expand pressure guan ji s one-way valve etc are formed , and the injection nozzle is made with stainless steel , and an injection nozzle seat board is processed by high-quality steel , but all the other part system iron casting are cast . the injection nozzle uses the structure form of many injection nozzles , and so that getting one vapour in the bigger water contact area , is favour of being in progress of heat exchange , and gains better vacuum effect . injection nozzle seat board process is precise , and the precision is higher , so that the injection rivers are accuray gathered at the same focal point . the direction dish is used to slow down the velocity of flow of steam ( or air ) , and makes even ground of the vapour gather ware room in order to avoid the injection rivers are oblique partially , and reduces lashing shooting efficacy . the whole device structure is tightly precisely , and intensity is also than the height , being used in the vacuum evaporation system because the fact that the suction that the condensation of ability handle condenser acted on with the vaccum pump acts on the incorporation and accomplishes at the same time in an equipment , has simplified the process flow greatly , than it original the device with vaccum pump and old type condenser , can economize vaccum pump and condenser , and divide the equipments such as ware etc , and still has the following merit : ( 1 ) the waterpower injector volume is small and weight is light and the structure is compact . and efficacy is again fairly higher , and the power consumption is lower than the vaccum pump system , and invests to economize . ( 2 ) operating the simple maintenance convenience , personnel manage the disuse specific duty , and owing to inorganic tool transmission ministry sake , so the noise hangs down , do not need to consume lubricating oil . ( 3 ) can install by the bit at outdoor bottom , it is few to cover an area of the area , and can economize factory building building area and installation charge |
