Maintenance and precautions for hot and cold impact testing machines

The hot and cold impact test chamber is suitable for the reliability and environmental stress screening test of industrial products. Most users do not know how to install the machine after buying it. The editor will tell you about the maintenance and precautions of the hot and cold impact test machine. Let’s learn it together.

1. Maintenance of hot and cold impact testing machine

1. The refrigeration system of the hot and cold impact test machine is the core of the test machine. All copper pipes must be inspected once a year for snow leakage. Each horn joint and welding interface. If there is any oil stain leak, please deal with it directly or inform the original manufacturer.

2. When opening and closing the door or taking the test object from the furnace, the items must not be allowed to come into contact with the glue edge on the door to prevent the glue edge from being damaged and shortened.

3. The ground around the fuselage and at the bottom should be kept clean at all times to avoid accidents and performance reduction due to large amounts of dust sucking into the unit.

4. The radiator (condenser) of the refrigeration unit of the hot and cold impact tester should be maintained regularly and kept clean. The dust-sticky condenser will cause the compressor's high-pressure switch to jump off and cause a false alarm. The condenser of the hot and cold impact test chamber should be maintained regularly and monthly. Use a vacuum cleaner to suck off the dust attached to the condenser heat dissipation mesh. After turning on the machine, use a hard brush or use a high-pressure air nozzle to blow the dust.

5. The high current contact of the distribution board is cleaned and inspected at least once a year. The loose contact will cause the entire equipment to be in a dangerous working state. At the very least, the components are burned out, and at worst, fire, alarm, or personal injury is very dangerous. When cleaning, use a vacuum cleaner to suck out the indoor dust.

6. Please do not debug the two overtemperature protectors in the distribution box casually. They have been adjusted when leaving the factory. This protection switch is used to protect the air incineration and water shortage alarm of heating pipes and humidification pipes. The set point of the hot and cold impact test chamber = temperature set point + 20℃ ~ 30℃

7. Inspection and maintenance of the waterway of the hot and cold impact tester. The water pipes of the waterway are devices that are prone to blockage and leaks. Please be sure to check regularly for any leakage and water blockage. If there is any, please eliminate them in time or notify the company.

8. When the test product time reaches the product,

2. Precautions for installing hot and cold impact test chambers

1. The heat dissipation efficiency of the machine and the ease of inspection and maintenance should be taken into account when installing the hot and cold impact test chamber.

2. In order to achieve stable performance of the equipment, air conditioning should be carried out in the installation room of the equipment and keep the indoor temperature between 10℃ and 30℃. The allowable operating ambient temperature range is 0° to 30°C.

3. Do not allow the sun to directly project onto the device. When the use of this device is outside this range, the safety device will start or the device will stop running.

4. Make the atmospheric environment of the installation site consistent with the general indoor air-conditioned atmospheric environment. If organic solvents, plasticizers, acids, alkalis or other chemicals are present in the air, components or coatings of the equipment will be corroded and damaged.

5. The floor of the hot and cold impact test chamber must be kept flat and have sufficient strength (3.4N/m2 or higher). Choose a location where both dust and vibration are less affected.

6. The equipment should be installed at a level.

7. Good ventilation should be maintained around the hot and cold impact test chamber. During operation, the equipment will radiate heat. If it is air-cooled hot and cold impact, it will directly discharge heat through the condensing air. When the room is small and the ventilation is not smooth, the indoor temperature will rise rapidly, causing the machine to stop running and alarm.

8. Install this equipment in a dry room.

9. The hot and cold impact test chamber should be installed nearby where power supply and sewer are equipped.

10. The installation of hot and cold impact test chambers should be kept away from flammable or explosive substances or other substances that may produce high heat.

11. This equipment should be installed in a place with very little dust. The wind condition makes it impossible to cause hypoxia even if the refrigerant (fluorocarbon) leaks from the equipment.

12. Maintain space and scattered laboratories to cool down. The staff must wear dry, electrical, and temperature-resistant gloves to pick up and place the products when the machine is turned off and the staff must wear dry, electrical, and temperature-resistant gloves.

9. The hot and cold impact test machine should remove internal impurities (items) before operation.

10. Clean the electric room at least once a year. Please use a vacuum cleaner to suck out the indoor dust. Clean the outside of the box of the hot and cold impact test chamber once or more a year. Wipe it with soapy water during cleaning.
