There are plenty of articles online devoted to maintaining constant temperature and humidity; however, few operators are available for maintenance. The operator did not seriously deal with the occurrence of the problem, and blamed the quality of the constant temperature and Humidity Chamber. In fact, it is caused by the failure of the operator to maintain the constant temperature and Humidity Chamber. As long as we properly maintain the equipment on a regular basis, the constant temperature and Humidity Chamber will rarely fail in long-term use. There is no need to repeat the importance of the daily maintenance of the constant temperature and humidity cabinet.
The first point: be sure to use pure water to humidify.
Second point: This constant temperature and Humidity Chamber cannot be placed in a place with water or sunlight.
The third point is divided into the following points:
1. This machine needs to be operated by designated personnel to avoid premature damage to the equipment.
2. This machine cannot be used for heating or test roasting. If it is necessary to test flammable, explosive, and corrosive items, the danger needs to be considered, otherwise unnecessary losses will be caused, or the machine cannot achieve the purpose of the test.
3. The amount of test object placed must not affect the air volume circuit of the Test Chamber; otherwise, its performance will be affected.
4. When in use, the door needs to be closed tightly; otherwise, the temperature and humidity will leak, and the performance will not be achieved.
5. After the positive temperature test is over, the operator needs to step back in the direction of opening the door when opening the door to prevent a large amount of temperature and humidity from gushing out of the temperature and humidity environment chamber and hurting people.
6. When opening and closing the door or taking the test object from the inside, the object must not touch the rubber edge of the door, so as to avoid damage to the rubber edge and shorten the service life.
7. The ground around and at the bottom of the fuselage should be kept clean at all times to prevent a large amount of dust from being sucked into the unit to cause accidents and reduce performance.
8. The refrigeration system is the core of the machine. Check all copper pipes for leaks annually.
9. The condenser of the refrigerator should be cleaned of dust regularly. Dust attached to the condenser will trip the high pressure switch of the compressor and generate an alarm. In order to avoid unnecessary trouble, it is generally cleaned every six months. After starting up, use a stiff brush or blow it clean with a high-pressure air nozzle.
10. The high-current contacts of the switchboard should be overhauled every six months. Loose contacts can put the entire device in a dangerous working condition and possibly burn components. In severe cases, fire, alarm, and personal injury may occur, which is very dangerous.
11. Humidifiers and water trays should be cleaned frequently to avoid Graduation from affecting steam discharge. It is generally cleaned once after the test is completed. After cleaning with a copper brush, rinse with water. Timely removal of scale will help prolong the service life of the humidification tube.
12. The wet cloth of the dry and wet bulb should be checked frequently. If it does not absorb water, it should be replaced in time, which is related to the accuracy of the humidity test. Generally, it is replaced once every three months.
13. Do not debug. The two over-temperature protectors in the distribution box have been adjusted randomly when they leave the factory to protect the heating tube and humidifying tube from burning and alarm for water shortage.
14. The water pipe in the waterway is a device that is easy to block and leak. Always check for leaks or blockages. If so, please remove or notify us in time.
15. After the product test is completed, it is necessary to take out the product in the power-on state, and the staff need to wear dry, anti-electricity, and temperature-resistant gloves to pick and place the product.
16. Non-professional personnel of the machine are not allowed to maintain and inspect the machine. In the process of maintenance and inspection, it needs to be carried out by full-time personnel. At the same time, there must be guardian supervision to prevent unknown personnel from energizing and closing the switch, causing electric shock, injury, and fire accidents.
17. We are not responsible for any loss caused by unauthorized modification of the machine during use.
18. We will not be responsible for any consequences caused by not following the precautions and requirements of the manual.
fourth point:
1. The power distribution room should be cleaned at least once a year. During the cleaning process, an industrial vacuum dryer should be used to remove indoor dust.
2. The outside of the constant temperature and Humidity Chamber should also be cleaned several times, and wipe it clean with soapy water during the cleaning process.
3. Before using the constant temperature and Humidity Chamber, the internal impurities should be cleaned up.
The regular maintenance of the constant temperature and Humidity Chamber is very important, and the requirements in all aspects are relatively strict. The operator is required to follow the standard provisions of the operating instructions.
