Two slot suspended basket type high and low temperature thermal shock test chamber

Two slot suspended basket type high and low temperature thermal shock test chamberMainly utilizing low-temperature and high-temperature thermal storage tanks, the valves are opened according to the action, and the low-temperature and high-temperature are quickly and rapidly sent into the test tank through the air supply system, thereby achieving a rapid temperature shock effect. The balanced temperature control system (BTC)+specially designed air supply circulation system controls the SSR in a P.I.D. manner, so that the heating amount of the system is equal to the heat loss amount, and can be used stably for a long time.

1、 Product features:

1. The two box equipment is divided into two parts: high temperature zone and low temperature zone. The test product is placed in a basket, and when impacted, the basket moves the test product into the high temperature zone or low temperature zone for balancing. The test product is dynamic;

2. Adopting a touch based graphical control interface, the operation is simple;

3. The impact method applies the air path switching method to import the temperature into the testing area for conducting cold and hot impact tests;

4. During high or low temperature impact, the maximum time can reach 999H and the maximum cycle period can reach 9999 times;

5. The system can be used as an automatic loop engine or manual selective impact;

6. The cooling system adopts a binary freezing system, which has a fast cooling effect and can be air-cooled or water-cooled;

7. It is not allowed to test the impact at room temperature.

2、 Mechanical purchase:

1. This system complies with the reliability test specifications for cold and hot cycles (CNS, MIL, IEC, etc.);

2. The test sample is placed on the sample rack, and a high-precision pneumatic system drives the valves in the thermal storage area or cold storage area to guide the airflow circulation to achieve uniform testing of hot and cold temperatures;

3. Adopting special design, space saving and moderate operating height, easy maintenance and repair;

4. High temperature resistant polyurethane foam and heat insulation high-density fiber cotton are used as the thermal insulation layer, and the newly designed K-type anti sweat duct system is used;

3、 Control system:

1. The controller adopts a touch type true color LCD microcomputer controller, which is beautiful and attractive;

2. The product adopts a resistive high-precision touch screen operation method, which allows users to directly click on the screen with a USB mouse or stylus to select functions or set parameters;

3. The programmable function has a capacity of 160Patten x 1600 steps x 999 cycles;

4. Screen display function: LCD display screen can display test conditions (including temperature range, cycle times, running time, and remaining time, etc.);

5. It has program control and constant value control functions, which facilitate the use of various production conditions;

6. The setting of temperature slope allows for free control of operating time and heating rate;

7. The reservation activation function will automatically run when the system time reaches the set time, allowing for flexible control of the operation time and working conditions of the aging room.

4、 Refrigeration system:

1. Throttle device: expansion valve+capillary tube;

2. Plate heat exchanger: stainless steel brazed plate heat exchanger;

3. Refrigeration compressor: fully enclosed (semi enclosed) low-noise piston compressor;

4. Evaporator: External finned internal threaded tube heat exchanger (customized with high-quality copper and clear water aluminum film special process);

5. Condenser: air-cooled type: external finned internal threaded tube heat exchanger (water-cooled type: shell and tube heat exchanger).
