一、概况：

SZ-Ⅱ自动纯水蒸馏器主要用于化学工业、医药工业、生物化学、科研单位实验室自制蒸馏水之用，主要材料由优质玻璃制成，在制作蒸馏水过程中不与任何金属接触，加热器采用石英玻璃。在一次、二次、三次蒸馏过程中，均有过热、缺水、断电保护装置，从而达到全自动蒸馏功能。

二、SZ-Ⅱ自动纯水蒸馏器使用说明：

在仪器使用前，首先检查仪器各部件，电源部分电路连接是否正确，试验结束后，请切断电源，以确保安全。

（1）把各横式烧瓶和冷凝管及水位器、磨口外套磁性浮子，蒸水接头和导管安装好，拧紧各自的紧定螺丝，把橡胶管及垫片套在石英加热管分别插入模式蒸馏中，拧紧螺母，把加热管电源线插入仪器标志的插座中。把温度控制器冷凝管安在外瓶中间，把干簧管插入导管中。

（2）SZ-Ⅲ自动纯水蒸馏器，首先打开自来水注水，直到多余的水从初蒸馏的水位器溢出口流出，这时横式蒸馏瓶中水位到一半高度后，（*上面）按C“开关”指示灯亮，仪器（中间）B一半水位高度后，按B指示灯亮，如不亮，反复校准调正干簧管位置，仪器进入二次蒸馏；纯水进入三次蒸馏的横式烧瓶中（*下面）一半水位高度后，按A开关，指示灯亮，这时三次蒸馏开始，以后随着水位高低变化可进入正常自动蒸馏状态。

SZ-Ⅱ自动纯水蒸馏器，待一次横式蒸馏瓶中水位到一半高度后（*上面）按B“开关”指示灯亮，仪器进入加热状态，开始蒸馏。纯水进入二次蒸馏的横式蒸馏瓶中。待二次蒸馏横式烧瓶中水位达到一半高度后按下（*下面）标有A“开关”指示亮，如不亮，反复校准调正干簧管位置。这二次蒸馏开始以后随着水位高低变化可进入正常自动蒸馏工作状态。

SZ-Ⅰ自动纯水蒸馏器，首先打开自来水注水，直到多余的水从初蒸馏的水位器溢出口流出，这时横式蒸馏瓶中水位到一半高度后，按“开关”指示灯亮，仪器进入加热状态，开始蒸馏。

（3）冷凝管过热：温度控制器触电会切断电源。待冷凝管温度降低后，仪器会自动接通电源。

（4）在操作过程中，调准干簧管和磁性浮子的配合位置应以水位降低能自动切断电源为准，从而达到自动控制水位的目的，应反复校准干簧断电器的灵敏度。

（5）SZ-Ⅱ自动纯水蒸馏器保养

在蒸馏一段时间水垢就积聚在横式烧瓶内及石英加热管表面上，需要进行清洗，但不需要拆下皮管。必须切断电源后加入小量浓盐酸，与瓶内的水稀释成盐酸。数分钟后，由水位器放出，用自来水冲洗数次，直到洁净为止。

I. Overview:

SZ-Ⅱ automatic water distiller mainly used for the chemical industry， pharmaceutical industry， biochemistry， scientific research units of the laboratory-made with distilled water， the main material are made from high quality glass， distilled water in the production process does not contact with any metal， heaters the use of quartz glass. In the first， second and third in the distillation process， there is overheating， water shortages， power protection devices to achieve the function of automatic distillation.

Second， SZ-Ⅱ automatic water distiller for use:

Before use in the apparatus， first of all inspection equipment parts， power part of the circuit connection is correct， after the end of the trial， please cut off power supply to ensure safety.

(1) to the flask and Condenser Horizontal and water， and ground magnetic float coat the mouth， steaming water connector and catheter installed， tightened their set screws tight， the rubber hose and gasket sets of quartz heating tube inserted mode of distillation， the fastening nut， the heating tube sign power supply cord into the outlet in the apparatus. Condenser temperature controller to an intermediate outer bottle， the reed switch in the catheter insertion.

(2) SZ-Ⅲ Automatic water distiller， first of all， open the tap water until the excess water from the beginning of distilled water exports out of overflow devices， when cross-type distillation bottle after the water level to half height， (top) by C "switch" light is bright， equipment (middle) B half of the high water level， press B indicator light， if not bright， repeated calibration is adjusted reed switch position， enter the second distillation apparatus; three distilled water into the flask in Horizontal (bottom) half of the high water level， press A switch， indicator light， when the beginning of the third distillation， after the change with the high and low water level can enter a state of normal auto-distillation.

SZ-Ⅱ automatic water distiller， to be a cross-type distillation bottle after the water level to half of the high (top) by B "switch" light is light， into the heating apparatus， and the beginning of distillation. Distilled water into the secondary distillation Horizontal bottle. Landscape to be the second distillation flask in the water level to reach half the height of press after (bottom) labeled A "switch" instruction bright， if not bright， repeated calibration is adjusted reed switch position. This is after the start of the second distillation as the level of changes in water level can be distilled into the normal working state automatically.

SZ-Ⅰ automatic water distiller， first of all， open the tap water until the excess water from the beginning of distilled water exports out of overflow devices， when cross-type distillation bottle after the water level to half height， according to "switch" light is light， apparatus to enter the heating， and the beginning of distillation.

(3) overheating Condenser: temperature controller will cut off the supply of electric shock. Condenser temperature to be lowered， the equipment will be automatically connected to power.

(4) In operation， the alignment and the magnetic reed switch with the position of the float should be to reduce the water level， whichever is automatically cut off power supply to achieve the purpose of automatic water level should be repeated reed switch off electrical calibration sensitivity.

(5) SZ-Ⅱ automatic water distiller maintenance

Distillation scale in a period of time to accumulate in the landscape on the flask and the quartz heating tube in the face of it， the need for cleansing， but do not require tube removed. Power must be cut off after a small amount of concentrated hydrochloric acid， diluted with water into a bottle of hydrochloric acid. A few minutes later， by the device to release the water level， wash several times with tap water until clean so far.
