The reactor www.wfanyingfu.com   consists of a kettle body, a kettle cover, a jacket, a stirrer and a transmission device, seal device, bearing etc.. Mixing form are generally anchored, agitator, turbine, promoting type or frame type and stirring device in high size is relatively large, available multilayer stirring blade, can also be based on user requirements of arbitrary choice. The jacket is arranged outside the kettle wall, or the heat exchange surface is arranged inside the device, and the heat transfer can be carried out by the outer circulation. Heating mode has electric heating, hot water heating, heat conduction oil circulation heating, far infrared heating reactor, outside (inside) coil heating, cooling method for jacket cooling and reactor coil cooling, stirring paddle form, etc.. Supporting seat or ear type bearing support. Speed over 160 RPM above should be used gear reducer. The number of openings, specifications or other requirements can be designed and produced according to the user's requirements.

1 usually under normal pressure or low pressure conditions using the packing seal, generally use the pressure of less than 2 kg.

2 mechanical seals are used in general medium pressure or vacuum conditions, and the general pressure is negative pressure or 40 kg.

3 high pressure or high pressure medium will be used in the case of high pressure seal, generally more than 14 kg of pressure. In addition to magnetic seal all use water cooling and other sealing form in more than 120 degrees will increase the cooling water jacket.

反应釜由釜体、釜盖、夹套、搅拌器、传动装置、轴封装置、支承等组成。搅拌形式一般有锚式、桨式、涡轮式、推进式或框式等,搅拌装置在高径比较大时,可用多层搅拌桨叶,也可根据用户的要求任意选配。并在釜壁外设置夹套,或在器内设置换热面,也可通过外循环进行换热。加热方式有电加热、热水加热、导热油循环加热、远红外加热反应釜、外()盘管加热等,冷却方式为夹套冷却和釜内盘管冷却,搅拌桨叶的形式等。支承座有支承式或耳式支座等。转速超过160转以上宜使用齿轮减速机。开孔数量、规格或其它要求可根据用户要求设计、制作。

    1.通常在常压或低压条件下采用填料密封,一般使用压力小于2公斤。

  2.在一般中等压力或抽真空情况会采用机械密封,一般压力为负压或40公斤。

  3.在高压或介质挥发性高得情况下会采用磁力密封,一般反应釜压力超过14公斤以上。除了磁力密封均采用水降温外,其他密封形式在超过120度以上会增加冷却水套。
