生化培养箱的使用、维护和常见光照培养箱的故障
来源:绿博仪器 时间:2019-11-21 21:10:50 点击数:
生化培养箱具有制冷和加热双向调温系统,温度可控的功能,是植物、生物、微生物、遗传、病毒、医学、环保等科研,教育部门不可缺少的实验室设备,广泛应用于低温恒温试验、培养试验、环境试验等等。
 
 
主要特点
 
1、箱体的隔热材料采用聚胺酯现场发泡的泡沫塑料,对外来热(冷)源有较强的抗干扰能力。
 
2、内腔采用工程塑料成型工艺制作,有较强的抗腐蚀能力。
 
3、全玻璃式箱门方便观察工作内腔。
 
4、为保护制冷压缩机,控制线路设计有断电保护和4分钟延时功能。
 
5、温度自动控制,采用红色LFD显示器显示数字直观清晰。
 
 
使用说明
 
1、将培养箱放于平整坚实的地面上,调节箱体下端两支撑螺杆,使箱体安置平稳。
 
2、插上电源插座(电源应有良好接地),按下“电源开关”,显示屏亮,此时显示屏所显示的是培养箱室内的实际温度及其工作时间。
 
3、时间设定:时间设定包括“分钟”与“小时”的设定。按下“SET”设置键,当“分钟”数码管显示位的右下角小数点亮,即进入“分钟”的设置状态,再按“”或“”键来确认培养箱本次工作的“分钟”时间(最长为59分钟);再按“SET”键,当“小时”数码管显示位的右下角小数点亮时,即进入“小时”的设置状态,再按“”或“”键来确认培养箱本次工作的“小时”时间(最长为99小时)。
 
4、温度设定:按下“SET”键,当温度显示最后一位数码管右下角的小数点亮时,即进入温度的设置状态,再按“”或“”键来确认培养箱本次设定温度(设定的温度范围为5~50)。
 
当上述3、4步骤完成时,按下“ENTER”确认键以确认培养箱本次工作时间及培养箱内的工作温度(设定温度)。注意:当温度设定确认之后,不能随意频繁的来回设定温度,以免压缩机启动频繁,造成压缩机出现过载现象,影响压缩机的使用寿命。
 
5、如需查看培养箱本次所设的工作时间及温度,按下“SET”键,显示面板即显示所设定的时间及温度,再按下“ENTER”键,培养箱的显示值回复到原来的工作状态。
 
6、如培养箱内需要照明时,按下“照明开关”即可;如箱内不需照明时,应将面板上的照明开关置于“关”的位置,以免影响上层温度。
 
 
注意事项及其维护
 
1、搬运时必须小心,箱体与水平面的夹角不得小于60°。
 
2、当使用温度较低时,培养箱内会有冷凝水产生,应定期倒掉位于箱内底部积水盘内的积水。
 
3、为了保持设备的美观,不得用酸或碱及其它腐蚀性物品来擦箱体表面,箱内可以用干布定期擦干。
 
4、当培养箱在停止使用时,应拔掉电源插头。
 
5、培养箱距墙壁的最小距离应大于10cm,以确保制冷系统散热良好。
 
6、室内应干燥,通风良好,相对湿度保持在85%以下,不应有腐蚀性物质存在,避免阳光直接照射在培养箱上。
 
7、所用电源必须具有可靠地线,确保培养箱地线与网电源的地线接触可靠,防止漏电或网电源意外造成的危害。
 
常见光照培养箱此类仪器常见故障有:压缩机不制冷,培养箱内温度不均匀,或者循环风口结冰等现象。
 
平衡模式工作下压缩机一直处于工作状态制冷效果比较好且对压缩机可以得到有效保养。
 
如果是单制式工作的话温度降低到一定数值时才工作,开关门时都会引起温度大幅度波动。造成压缩机平凡启动容易缩短其使用寿命。
 
温度不均匀:有可能是排放物品过于密集造成或者箱内循环风机不工作用长光照的话时间久灯泡容易发热也会造成温度不均匀出风口结冰:每种制冷的仪器都会有化霜周期,在此期间内压缩机不制冷。靠加热元件将冷凝器上的冰融化。融化后的水很有可能会聚集到出风口最后导致结冰。
Biochemical incubator has the function of refrigeration and heating bidirectional temperature-regulating system and temperature controllable. It is an indispensable laboratory equipment for scientific research of plants, biology, microorganism, heredity, virus, medicine, environmental protection and other educational departments. It is widely used in low temperature and constant temperature test, culture test, environmental test and so on.
 
 
 
 
 
The main features
 
 
 
1. The insulation material of the box body adopts the foam plastic foamed by polyurethane, which has strong anti-interference ability to the external heat (cold) source.
 
 
 
2, the inner cavity is made by engineering plastic molding process, with strong corrosion resistance.
 
 
 
3. All-glass door is convenient to observe the working inner cavity.
 
 
 
4. In order to protect the refrigeration compressor, the control circuit is designed with the function of power off protection and 4-minute delay.
 
 
 
5, automatic temperature control, red LFD display digital intuitive and clear.
 
 
 
 
 
Directions for use
 
 
 
1. Place the incubator on a flat and solid ground and adjust the two supporting screws at the lower end of the cabinet to make the housing stable.
 
 
 
2. Plug in the socket (the power should be well grounded), press the "power switch", and the display screen will be on. The display screen shows the actual temperature and working time of the incubator room.
 
 
 
3. Time setting: time setting includes "minutes" and "hours". Press "SET" to enter the setting state of "minute" when the decimal point in the lower right corner of the display position of "minute" digital tube is bright. Then press "" or" "to confirm the" minute "time of the incubator work (the longest is 59 minutes). Press "SET" key again, when the decimal point in the lower right corner of the display position of "hour" digital tube is bright, that is to enter the setting state of "hour", and then press "" or" "key to confirm the" hour "time of the incubator work (the longest is 99 hours).
 
 
 
4, temperature setting: press "SET" button, when the temperature shows the last digit digital tube at the lower right corner of the decimal point, that is, enter the temperature setting state, and then press "" or" "button to confirm the incubator SET temperature (SET the temperature range of 5 ~ 50).
 
 
 
When the above steps 3 and 4 are completed, press "ENTER" to confirm the working time and working temperature in the incubator (set temperature). Note: when the temperature setting is confirmed, it is not allowed to set the temperature back and forth frequently, so as to avoid frequent startup of the compressor, which may cause overload of the compressor and affect the service life of the compressor.
 
 
 
5. If you need to check the working time and temperature SET by the incubator, press "SET" and the display panel will display the SET time and temperature. Then press "ENTER" and the display value of the incubator will return to the original working state.
 
 
 
6. If the incubator needs lighting, press the "lighting switch"; If the box does not need lighting, the lighting switch on the panel should be placed in the "off" position, so as not to affect the upper temperature.
 
 
 
 
 
Notes and maintenance
 
 
 
1. Care must be taken during handling. The Angle between the box body and the horizontal plane should not be less than 60°.
 
 
 
2. When the temperature is low, there will be condensed water in the incubator, and the water in the bottom of the tank should be poured out periodically.
 
 
 
3, in order to maintain the appearance of the equipment, do not use acid or alkali or other corrosive substances to wipe the surface of the box, the box can be wiped dry with dry cloth regularly.
 
 
 
4. Unplug the incubator when it is not in use.
 
 
 
5. The minimum distance from the incubator to the wall should be more than 10cm to ensure good heat dissipation of the refrigeration system.
 
 
 
6. The room should be dry and well-ventilated, with relative humidity below 85%, no corrosive substances, and avoid direct sunlight on the incubator.
 
 
 
7. The power supply must have a reliable ground wire to ensure that the ground wire of the cultivation box is in reliable contact with the ground wire of the network power supply to prevent the damage caused by leakage or accident of the network power supply.
 
 
 
Common failures of such instruments include: the compressor is not refrigerated, the temperature in the incubator is not even, or the circulation tuyere is frozen.
 
 
 
Under balanced mode, the compressor is always in working state with good refrigeration effect and can be effectively maintained.
 
 
 
If it is a single system of work when the temperature drops to a certain number of work, open or close the door will cause a large temperature fluctuations. Cause the compressor ordinary start easy to shorten its service life.
 
 
 
Uneven temperature: it is possible that the discharge items are too dense or the circulation fan in the box is not working for a long time. If the bulb is prone to heat for a long time, it will also cause uneven temperature. The air outlet will freeze. Use the heating element to melt the ice on the condenser. The melted water is likely to accumulate in the vents and freeze.
