Low temperature thermal shock test chamber

Low temperature thermal shock test chamberThe system structure is divided into three parts: a high-temperature tank (preheating zone), a low-temperature tank (pre cooling zone), and a test chamber (testing zone). The sample is placed in the testing zone, and during the impact, the temperature of the high-temperature or low-temperature zone is driven into the testing zone by a high-pressure cylinder for temperature impact, thereby achieving the purpose of drastic temperature changes. The test product is static. This test chamber is suitable for assessing the ability of complete machine products, components, parts, materials, etc. to withstand rapid temperature changes. The temperature shock test is used to evaluate the chemical changes or physical damage caused by thermal expansion and contraction of the test sample in the shortest possible time, and can understand the impact of temperature changes on the test sample one or multiple times in a row. The main parameters that affect the temperature change test are the high and low temperature values within the temperature change range, the holding time of the test sample at high and low temperatures, and the number of cycles of the test. The thermal shock box is electronic, LED， Metal, plastic, rubber, coatings, paints, electronics and other material industriesTesting equipment.

Low temperature thermal shock test chamberTechnical Specifications:

Low temperature thermal shock test chamberrunning program:

1.Power on/off methods

2.Power on: When the power is turned on, please gradually turn on the machine from the power source switch to the machine switch.

3.Shutdown: When the power is turned off and the machine is not in use for a short period of time, simply turn off the control panel switch. If the machine is not used for a long time, please turn off the residual current circuit breaker on the machine.

4. After booting up, wait for the meter to display a normal screen before pre planning the program to be executed and setting the curve graph,In order to smoothly carry out the setup work.

5. The set values of temperature and time should be in accordance with the requirements of the user's tested product.

6. The setting of each function of the controller must be operated by dedicated personnel or in accordance with the controller's instructions.

7. After setting up each menu, the machine door must be closed tightly before it can operate normally.

8. At the initial operation of the machine,Be sure to pay attention to the direction of the running motor and the direction of the three-phase motor.

9. Press the operation switch of the controller to operate the machine according to the set temperature.

10. When the temperature reaches the user's product requirements and the machine needs to be shut down, the power switch on the panel must be turned off before the product can be removed or placed from it.

11. Instructions for using program settings and manual control,Please refer to the controller operation instructions. For specific operation of the controller, please refer to the controller manual.

12. If any malfunction occurs,The display screen of this machine immediately shows the location of the fault,The buzzer will sound,After troubleshooting,Please press the button on the screen(reset switch)key,Then restart the testing machine.

When there is an emergency that requires stopping the test, please press the emergency switch button to stop the test. To restore it, rotate this button to the right.

　　　Precautions for operation:

1. Try to avoid shutting down and restarting the refrigeration unit within three minutes to avoid affecting the function of the compressor

2. This machine absolutely prohibits heating or testing explosive, flammable, and highly corrosive substances. Otherwise, it will cause unnecessary losses or the machine cannot conduct tests on it.

3. The amount of test material placed should not affect the air circulation of the test box, otherwise it will affect the performance of the machine.

4. When using, the door should be tightly closed to prevent temperature leakage and prevent it from reaching the performance area.

5. Designate personnel to operate this machine to avoid premature damage.

6. When the machine is running,Try to avoid opening the box door as much as possible,Because when working at low temperatures,Opening the box door can easily cause ice sealing in the internal evaporator and other parts,Especially the lower the temperature,The more severe the situation,If it must be opened,Then the time should be shortened as much as possible.

7. When the operation is completed,Wait until the machine has come to a complete stop before opening the door to retrieve the test sample.

8. During operation,Unless absolutely necessary,Please do not open the box door,Otherwise, it may lead to the following adverse consequences:

a. High temperature gas rushes out of the box Very dangerous!

b. The inside of the box door still maintains high and low temperatures... causing injury!

c. High temperature air may trigger a fire alarm,Causing misoperation!

d. Opening method:When opening the door, the operator must move backwards along the direction of the door to prevent a large amount of hot air from escaping and injuring people inside the machine.

9. Please note that this device must be safely and securely grounded,To avoid static electricity induction!

10. Circuit shorts and temperature sensors device,Provide local test samples and operator safety protection,Please check regularly.

11. In operation,Please do not touch the inspection with your hands,To avoid electric shock or injury from the fan,And danger arises,Therefore, please stop running first,Turn off the power before repairing.

12. Non staff members are not allowed to carry out maintenance and inspection on this machine. During maintenance and inspection, it should be carried out by dedicated personnel, and there should be a supervisor to supervise and prevent uninformed personnel from turning on and off the power, causing electric shock and injury.

After carefully reading the controller manual and related manuals,Only then can the machine be operated.
