What are the precautions for the installation and use of hot and cold impact test chambers

The hot and cold impact test chamber is suitable for the reliability and environmental stress screening test of industrial products. It has the characteristics of accurate temperature control accuracy and wide control range. It uses low- and high-temperature cold storage and heat storage tanks, open the DAMPER according to the needs of the operation, and introduces the hot and cold temperatures in the storage tank into the test tank to achieve a rapid temperature impact effect. It adopts a balanced temperature control system (BTC) + special adjustable louver air supply circulation system, and controls the SSR in P.I.D. method, so that the heating amount of the system is equal to the heat loss amount, so it can be used stably for a long time. After purchasing any equipment, we need to install it appropriately to make the machine run smoother. So what are the precautions for the installation and use of the hot and cold impact test chamber? Please follow me to take a look.

1. The installation precautions for hot and cold impact test chambers are as follows:

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 hot and cold impact test chamber 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 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. This equipment 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.

Installation matters for distribution fortifications for hot and cold impact test chamber:

1. Pay attention to the power capacity and do not use one power supply at the same time for multiple machines to avoid voltage drop, affecting machine performance, and even causing failure and shutdown;

2. The rear ground terminal, please ground. The grounding wire must be properly constructed. According to the technical standards of electrical equipment, the grounding resistance of the third grounding project should be maintained at 50 ohms;

3. If you connect the grounding wire to the water pipe, the water pipe must be a metal pipe that is connected to the ground (and all metal pipes can be effectively grounded);

4. Do not connect the grounding wire to oil or gas pipe;

2. The following points are precautions for the use of the hot and cold impact test chamber:

1. This machine is absolutely forbidden to heat or test explosive and flammable substances, otherwise unnecessary losses will be caused, or this machine cannot test them.

2. Try to avoid turning off the refrigeration unit within three minutes to avoid affecting the function of the compressor;

3. When using the door, close it properly and tightly, otherwise the temperature will leak out and the performance area will not be reached.

4. The amount of test items placed in the hot and cold impact test chamber shall not affect the air volume circulation of the test chamber, otherwise it will affect the performance of the machine.

5. When this machine is running, try to avoid opening the box door, because when opening the box door is low, it is easy to cause ice sealing in the internal evaporator and other parts, especially the lower the temperature, the more serious the situation. If it must be opened, the time should be shortened as much as possible.

6. Designate personnel to operate this machine to avoid early damage to the machine.

7. During the operation, unless it is absolutely necessary, please do not open the box door, otherwise the following adverse consequences may be caused: high-temperature gas rushes out of the box, which is very dangerous!

8. When the operation is completed, the door can be opened to retrieve the test items after the machine is completely stopped.

Door opening method: When the operator opens the door, he must move backward along the direction of opening the door to prevent a large amount of heat from gushing out from the machine and injuring people. The inside of the box door is still maintained at high and low temperatures to cause damage. High temperature air may trigger a fire alarm and cause malfunctions!

9. Please note that the hot and cold impact test chamber must be safely and resolutely grounded to avoid electrostatic induction!

10. Circuit short-circuiter and temperature overtemperature protector provide safety protection for this machine test items and operators, so please check regularly.

11. During operation, please do not check with your hands to avoid electric shock or damage to the fan, which may cause danger. Therefore, please stop running first, turn off the power before repairing.
