一、概況：

SZ-Ⅱ自動純水蒸餾器主要用于化學工業、醫藥工業、生物化學、科研單位實驗室自制蒸餾水之用，主要材料由優質玻璃制成，在制作蒸餾水過程中不與任何金屬接觸，加熱器采用石英玻璃。在一次、二次、三次蒸餾過程中，均有過熱、缺水、斷電保護裝置，從而達到全自動蒸餾功能。

二、SZ-Ⅱ自動純水蒸餾器使用說明：

在儀器使用前，首先檢查儀器各部件，電源部分電路連接是否正確，試驗結束后，請切斷電源，以確保安全。

（1）把各橫式燒瓶和冷凝管及水位器、磨口外套磁性浮子，蒸水接頭和導管安裝好，擰緊各自的緊定螺絲，把橡膠管及墊片套在石英加熱管分別插入模式蒸餾中，擰緊螺母，把加熱管電源線插入儀器標志的插座中。把溫度控制器冷凝管安在外瓶中間，把干簧管插入導管中。

（2）SZ-Ⅲ自動純水蒸餾器，首先打開自來水注水，直到多余的水從初蒸餾的水位器溢出口流出，這時橫式蒸餾瓶中水位到一半高度后，（*上面）按C“開關”指示燈亮，儀器（中間）B一半水位高度后，按B指示燈亮，如不亮，反復校準調正干簧管位置，儀器進入二次蒸餾；純水進入三次蒸餾的橫式燒瓶中（*下面）一半水位高度后，按A開關，指示燈亮，這時三次蒸餾開始，以后隨著水位高低變化可進入正常自動蒸餾狀態。

SZ-Ⅱ自動純水蒸餾器，待一次橫式蒸餾瓶中水位到一半高度后（*上面）按B“開關”指示燈亮，儀器進入加熱狀態，開始蒸餾。純水進入二次蒸餾的橫式蒸餾瓶中。待二次蒸餾橫式燒瓶中水位達到一半高度后按下（*下面）標有A“開關”指示亮，如不亮，反復校準調正干簧管位置。這二次蒸餾開始以后隨著水位高低變化可進入正常自動蒸餾工作狀態。

SZ-Ⅰ自動純水蒸餾器，首先打開自來水注水，直到多余的水從初蒸餾的水位器溢出口流出，這時橫式蒸餾瓶中水位到一半高度后，按“開關”指示燈亮，儀器進入加熱狀態，開始蒸餾。

（3）冷凝管過熱：溫度控制器觸電會切斷電源。待冷凝管溫度降低后，儀器會自動接通電源。

（4）在操作過程中，調準干簧管和磁性浮子的配合位置應以水位降低能自動切斷電源為準，從而達到自動控制水位的目的，應反復校準干簧斷電器的靈敏度。

（5）SZ-Ⅱ自動純水蒸餾器保養

在蒸餾一段時間水垢就積聚在橫式燒瓶內及石英加熱管表面上，需要進行清洗，但不需要拆下皮管。必須切斷電源后加入小量濃鹽酸，與瓶內的水稀釋成鹽酸。數分鐘后，由水位器放出，用自來水沖洗數次，直到潔凈為止。

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.
