Environmental Equipment Maintenance Methods Technical Support

The maintenance methods for the high-low temperature impact test box and the thermal shock test box are as follows:

1. The radiator (condenser) of the refrigeration unit should be regularly maintained and kept clean. The dusty paste condenser will make the high pressure switch of the compressor trip off and generate false alarms. The condenser should be maintained on a regular monthly basis. Use a vacuum cleaner to suck the dust attached to the condenser cooling mesh or use a hard brush Brush or blow dust with high-pressure gas nozzle;

2. When switching the door or taking the test object from the furnace, do not allow the article to come into contact with the rubber on the door to prevent the rubber edge from being damaged and shortening the life.

3. The ground around the bottom of the fuselage and the bottom must be kept clean at all times so as not to inhale large amounts of dust into the unit to cause accidents and reduce performance;

4. The freezing system is the core of this machine. Please inspect all copper pipes for leak-free snow conditions for half a year. The joints and welds of the horns shall be leaked if there is grease.

5. The high-current contact of the switchboard, the power distribution room is cleaned and overhauled at least twice a year. The loosening of the contact will cause the entire equipment to be in a dangerous working state, and the components will be burned lightly, and fire, alarm, and personal injury will be very dangerous. Cleaning When the vacuum cleaner is used to remove indoor dust,

6. The two over-temperature protector setting values ​​in the distribution box should not be adjusted easily. It is adjusted when leaving the factory. This protection switch is used to protect the heating pipe and burn the alarm. Set point = temperature set point + 20°C～30°C;

7. When the product is taken after the test product time arrives, it must be in the off state and the staff must wear dry, anti-electricity, temperature resistant gloves to pick and place the product;

8. External cleaning and maintenance inside the box;

9. The machine should remove the internal impurities (objects) before operation;

10. Clean the power distribution room at least once a year or more. When cleaning, use a vacuum cleaner to remove dust from the room. The exterior of the cabinet must be cleaned more than once a year, and it can be wiped with soapy water when cleaning;
