W水力喷射器

产品概述：;水力喷射器是一种具有抽真空、冷凝、排水等三种有效能的机械装置。它是利用一定压力的水流通过对称均布成一顿斜度的喷咀喷出,聚合在一个焦点上。由于喷射水流速很高,于是周围形成负压使器室内产生真空、另外由于二次蒸汽与喷射水流直接接触,进行热交换,绝大部份的蒸汽冷凝成水,少量未被冷凝的蒸汽与不凝结的气体亦由于与高速喷射的水流互相摩擦,混合与挤压,通过扩压管被排除,使器室内形成更高的真空。水力喷射器应用极为广泛,主要用于真空与蒸发系统,进行真空抽水、真空蒸发、真空过滤、真空结晶、干燥、脱臭等工艺,是制糖、制药、化工、食品、制盐、味精、牛奶、发酵以及一些轻工、国防部门广泛需求的设备。但目前生产水力喷射器的制造厂较少,品种亦不齐,为此,我单位近年来不断改进设计。采用多啧咀与汽环(导向盘)等结构,以及用多级泵进水,低位安装,只需安装高度4.5米,完善与提高了其工作性能,具有一定的先进性、是真空冷凝设备的一种革新。

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

结构特点水力喷射器由器体、器盖、喷咀、喷咀座板、导向盘、扩压管及单向阀等部件组成,喷咀用不锈钢制造,喷咀座板由**钢加工,其余零件则系铸铁铸造。喷咀采用多喷咀的结构形式,以便得到较大的水一汽接触面积,有利于热交换的进行,获得较好的真空效果。喷咀座板加工精密,精度较高,以便喷射水流准确地聚集在同一的焦点。导向盘用于减慢蒸汽(或空气)的流速,使蒸气均匀地导入器室以免喷射水流偏斜,降低抽射效能。整个装置结构紧凑精密,强度亦较高,用于真空蒸发系统中,由于能把冷凝器的冷凝作用与真空泵的抽气作用合并在一个设备中同时完成,大大地简化了工艺流程,比之原来用真空泵与旧式冷凝器的装置,可以节省去真空泵、冷凝器,分水器等设备,并且还有下列优点:(1)水力喷射器体积小、重量轻、结构紧凑。而效能又比较高,耗电量低于真空泵系统,投资省。(2)操作简单维修方便,不用专职人员管理,由于无机械传动部份,所以噪声低,不需消耗润滑油。(3)可以室外底位安装,占地面积少,可以节省厂房建筑面积与安装费用

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 accurately 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
