Knowledge of constant temperature and humidity test box maintenance
Author: BIOLAB Published: 2016-9-9 Visits: 753

The maintenance of Shanghai Boss constant temperature and humidity test box, if the machine is often used for testing, routine maintenance is very important. Now let's take a look at how to maintain the high and low temperature test box:

1.The constant temperature and humidity test chamber is generally relatively high. We recommend that it be placed in a relatively benign temperature environment. Our empirical temperature value is 8 ° C ~ 23 ° C. For laboratories that do not have this condition, they must be equipped with appropriate air conditioning. Device.

2. Adhere to the professional management of specialized personnel, and send personnel to the supplier factory for training and learning from time to time to obtain more professional maintenance and repair experience and ability.

3. Fixed cleaning of the condenser every 3 months: For compressors that are air-cooled, the condenser fan should be regularly inspected and the condenser should be decontaminated and dusted to ensure its good ventilation and heat exchange performance.

4. Regularly clean the evaporator: due to the different cleanliness of the test products, under the action of forced air circulation, many small particles such as dust will condense on the evaporator, and it should be cleaned regularly.

5.Cleaning and balancing of circulating air blades and condenser fans: Similar to cleaning the evaporator, because the working environment of the test box is different, many small particles such as dust and other particles will condense on the circulating air blades and condenser fans and should be cleaned regularly.

6. Waterway and humidifier cleaning: If the waterway is not smooth and the humidifier is fouled, it will easily lead to dry burning of the humidifier and may damage the humidifier, so the waterway and humidifier must be cleaned regularly.

7. Persist to set the temperature near the ambient temperature after each test, cut off the power after working for about 30 minutes, and wipe the inner wall of the work chamber clean.

8.If the equipment needs to be relocated, it is best to be carried out under the guidance of Shanghai Boshang's technical staff to avoid unnecessary damage or damage to the equipment.

9.When the machine is not used for a long period of time, the product should be regularly powered on every half a month for a period of not less than 1 hour.

由于恒温恒湿试验箱基本由电气、制冷和机械多个系统组成,因此一旦设备出现问题,应全面地对整个设备系统进行检查和综合分析.一般来说分析判断的过程可以先"外"后"里",即首先排除外部因素后,根据故障现象对设备进行先系统分解.后对系统综合的分析与判断.或可以采用倒推的方法查找故障原因:首先按照电气接线图查找是否电气系统有问题,最后查找是否制冷系统的问题.在没弄清故障原因前,切不可肓目拆卸或更换零部件,以免造成不必要的麻烦. 10.Maintenance principle: Since the constant temperature and humidity test box is basically composed of multiple systems of electrical, refrigeration and machinery, once the equipment has a problem, the entire equipment system should be checked and comprehensively analyzed. Generally speaking, the process of analysis and judgment can be First "out" and "in", that is, after the external factors are eliminated, the equipment is systematically decomposed according to the failure phenomenon. Then the system is analyzed and judged comprehensively. Or you can use the reverse method to find the cause of the failure: first, according to the electrical wiring Figure to find out if there is a problem with the electrical system, and finally find out if there is a problem with the refrigeration system. Do not disassemble or replace parts before you figure out the cause of the failure to avoid unnecessary trouble.
