1. The radiator (condenser) of the thermal shock chamber refrigeration unit should be kept clean within the specified time. Dirt that sticks to the condenser can cause the compressor's high pressure switch to trip and cause false alarms. The condenser should be maintained regularly and monthly. Use a vacuum cleaner to absorb the dust attached to the condenser cooling net, or use a hard brush after starting the machine. Brush it, or blow it off with a high-pressure air nozzle.
2. When opening and closing the door of the thermal shock chamber or taking the test object out of the furnace, do not let the object touch the glued edge of the door to prevent the glued edge from being damaged and shorten its service life.
3. The ground around the fuselage and the bottom of the thermal shock chamber should always be kept clean to prevent a large amount of dust from being sucked into the unit, causing accidents and reducing performance.
4. The refrigeration system of the thermal shock chamber is the core of the machine. Check all copper piping semi-annually for leaks. If there is oil leakage from the speaker joint and welding joint, please notify the company or deal with it directly.
5. The high-current contacts of the power distribution board in the thermal shock room should be cleaned and repaired more than once a year in the power distribution room. Loose contacts can put the entire device in a dangerous working condition. In light cases, components will be burned, in heavy cases fire, alarms and personal injury can be very dangerous. When cleaning, use a vacuum cleaner to absorb house dust.
6. Do not adjust the setting values of the two over-temperature protectors in the distribution box of the thermal shock chamber. Adjusted at the factory. The protection switch is used to protect the heating tube from air burning and alarm. Set point = temperature set point + 20°C~30°C.
7. When taking the product after the test time in the thermal shock chamber is up, it needs to be in a closed state, and the staff need to wear dry, anti-electricity and high-temperature-resistant gloves to take and place the product.
8. Thermal shock cleaning and maintenance indoors and outdoors.
9. Internal impurities should be removed before the machine runs in the thermal shock chamber.
10. The power distribution room of the thermal shock room should be cleaned at least once a year. When cleaning, use a vacuum cleaner to absorb house dust. The outside of the box needs to be cleaned more than once a year, and it can be wiped with soapy water when cleaning.
