QUICK DETAILS

High-low temperature impact test box, also known as hot and cold impact test box, is a necessary test equipment for metal, plastics, rubber, electronics and other materials industries. It is used to test material structure or composite materials, and is subjected to very high temperature and low temperature in an instant. The extent of endurance in the environment allows the chemical change or physical damage caused by thermal expansion and contraction of the test specimen to be detected in the shortest possible time. The device is used in electronic and electrical components, automation components, communication components, auto parts, metals, chemical materials, plastics and other industries, defense industry, aerospace, military industry, BGA, PCB based pull, electronic chip IC, semiconductor ceramics and high Changes in the physical properties of molecular materials, testing of their repeated resistance to high and low temperatures, and chemical or physical damage to the products resulting from thermal expansion and contraction, confirming the quality of products, from precision ICs to heavy mechanical components, Will be used, is an essential test box for product testing in various fields

High and low temperature impact test boxes are divided into three boxes and two boxes according to test requirements and test standards. The difference is that the test method and internal structure are different. The three-box type is divided into a cold storage room, a regenerator room and a test room, and the product is placed in the test room during the test. The two-box type is divided into a high-temperature room and a low-temperature room, and the high-low temperature is switched by the motor-driven basket movement. The product is placed in the basket and is moved along with the basket.

 

 

STRUCTURE AND MATERIALS

1. Outer box: cold-rolled steel electrostatic spraying;
2. Inner box: SUS304# stainless steel;
3. Moisturizing material: rigid polyurethane foam and glass wool;
4. Door: single test chamber open door;
5. Seal: imported silicone seal;
6. Switch damper:
A. Divided into high-temperature tanks, low-temperature tanks, and test tanks; high and low-temperature tanks are used as energy reserves, and test products are placed in the test tanks.
B. When the high-temperature impact occurs, the low-temperature damper closes the high-temperature damper and the hot air blows into the test tank from the high-temperature tank.
C. At low temperature impact, the high temperature damper is closed and the low temperature damper is opened. Cold air is blown into the test tank from the low temperature tank.

 

FUNCTIONS

1. Over-temperature protection function;
2. With no fuse protection switch;
3. Heater over-temperature protection switch;
4. The compressor is overloaded and overheated;
5. Compressor high pressure protection;
6. System over-current protection device;
7. Controller self-diagnosis failure and display;

 

MULTI SYSTEMS

 

1. COOLING SYSTEM

Refrigeration method: mechanical piston compressor;

System features: Automatically switch the cooling system flow according to different working conditions, and cut off the redundant system in order to achieve energy-saving operation.
1) Cooling control
Multi-stage evaporator combination for more uniform and efficient cold exchange;
Efficiency and cooling output, flow control from the respective matching thermal expansion;
Expansion valve automatic adjustment;
2) Impact at different temperatures
The multi-stage evaporator structure is correspondingly cut off to control the evaporation area and cooling;
The expansion valve is matched and the output of the refrigeration system is used to reasonably reduce heating;
And the output of the device, to achieve a constant energy saving;

 

2. Heating system and air temperature measuring system

Air characteristics: forced air circulation
Heating tube: fin-type nickel-chromium alloy heating tube;
Control mode: the controller output signal through SSR solid state relays to achieve high-precision non-contact switch control;

 

3. Touch screen control system

1). Temperature and humidity curve:
Paperless record: built-in recording program, controller memory can be stored;
24H runs for 300 days. It is easy to generate temperature and humidity curves automatically.
And save it as an XLS form;
2). Perfect interface:
External USB port: It can be directly connected to the printer, and the local data can be printed by the line. The USB port can be used to easily carry out historical curve and other data export.
Foreign LAN standard network interface: no special configuration server, can access the company's computer area network, a maximum of 16 devices can be connected and monitored, convenient;
3). Real-time monitoring:
Monitor the operating status of 1~16 controllers at the same time, such as monitoring controller real-time data, signal point status, actual output status, etc.
Support remote (external network) troubleshooting:
Technicians can use the network to help the customer to set aside, open IE browser, enter the IP address of the controller, you can enter the login interface to select operations or monitor for diagnosis;
4). Fault display:
10 sets of fault alarm output, humanized prompts in both English and Chinese indicate the cause of the fault and how to eliminate it;
5). Appointment start:
All test conditions can be set to reserve start function
