JULABO FP50-HL加热制冷循环浴槽技术参数
低温恒温槽使用说明书
低温冷却槽使用说明书一、用途：低温冷却槽由于具有降温和升温的双重功能，同时增加了内外循环功能，从而扩大了该款该仪器的使用范围，除了具有恒温水槽（仅具有加热功能）的所有特点以外，还可以用来做微生物的低温培养、化合物的低温反应、当使用外循环时可以用来对精密仪器的冷却、双层玻璃反应釜的低温反应等，所以低温恒温槽又称为低温恒温反应浴、低温冷却槽、低温冷却循环泵。
该仪器广泛用于各科研、农林、卫生、医疗、制药等单位的实验室。
二、制冷原理：制冷系统由4个基本部分即压缩机、冷凝器、节流器、蒸发器组成。
由铜管将四大件按一定顺序连接成一个封闭系统，系统内充注一定量的制冷剂，压缩机吸入来自蒸发器的低温低压的氟里昂气体，经压缩机压缩成高温高压的氟里昂气体(此时对外散发热量)，然后流经热力膨胀阀(毛细管)，节流成低温低压的氟里昂气液两相(气体和液体混合物)物体，此时该混合物流进蒸发器时空间瞬间变大，液体全部变成气体，在变化过程中制冷剂要吸收大量热量，从而降低水槽内的水温，此时又成为低温低压的氟里昂气体，低温低压的氟里昂气体又被压缩机吸人。
如此压缩-----冷凝----节流----蒸发反复循环，制冷剂不断带走水槽内的热量，从而降低了水的温度，在水温达到设定值时，压缩机停止工作，当水温超过设定值时，压缩机再次启动，如此周而复始循环工作，达到恒温的目的。
三、特点：1、风冷式全封闭压缩机制冷，微电脑控制器控制制冷的开启、关闭，制冷系统具有延时、过热、过电流、过电压多种保护装置。
2、循环泵可将机内冷却液体输出，冷却或恒温机外实验容器以及用来建立第二恒温场。
3、循环系统采用优质不锈钢水泵，具有防腐蚀、耐低温的特点。
4、超温报警，超温保护功能。
5、温控仪故障代码提示功能。
6、所有操作都在微电脑控制器上，按动触摸软键即可完成设定，循环、加热和制冷功能，操作简便、直观。
五、使用环境：1、环境温度：0-35℃2、相对湿度：≤75%RH3、使用电源：220v 50Hz六、使用方法：（1）用前须知：1. 首次使用时，应拿开上盖，加入水或防冻液，加至离顶盖上口3cm 为止。

搅拌器以小型电动机带动，用变速器或变压器来调整搅拌速度。
试验室常用的继电器有电子管继电器和晶体管继电器。
衡量恒温水浴的品质好坏，以水浴灵敏度为衡定标准。
假如要求设定的温度与室温相差不大，通常可用20dm3的圆形玻璃缸作容器。
电加热器热容量小，导热性好，功率适当。
室温过低时，则应选用较大功率或采纳两组加热器。
继电器与加热器和接触温度计相连，起到控温作用。
低温恒温反应浴的日常维护与保养：（1）低温恒温反应浴电源：220V50Hz，电源功率应大于仪器的总功率，电源必须有良好接地装置。

Replace the tubing andreplenish the bath tank with the bath fluid.•The wires of the working temperature sensor are interrupted orshort-circuited.After eliminating the malfunction, press the mains power switch off and on again to cancel the alarm state.If the unit cannot be returned to operation, contact an authorized JULABO service station.Disturbances that are not indicated.Pump motor overload protectionThe pump motor is protected against overloading. After a shortcooling interval, the motor will automatically start running.Mains fusesThe mains fuses on the rear of the unit are safety cutouts – 15A.Safety recommendations6.Safety recommendationsFollow the safety recommendations to prevent damage to persons orproperty. Further, the valid safety instructions for working placesmust be followed.ED217.Cleaning the unitFor cleaning the bath tank and the immersed parts of the circulator, use low surface tension water (e.g., soap suds).Clean the outside of the unit using a wet cloth and low surface tension water.The circulator is designed for continuous operation under normal conditions. Periodic maintenance is not required.The tank should be filled only with a bath fluid recommended byJULABO. To avoid contamination, it is essential to change the bath fluid from time to time.RepairsBefore asking for a service technician or returning a JULABOcirculator for repair, please contact an authorized JULABO service station.When returning the unit:• Clean the unit in order to avoid any harm to the service personnel.• Attach a short fault description.• During transport the unit has to stand upright.
