HZAOC AK-RJX-8S Thermal Engine Testing Machine (Vertical) is a performance testing equipment specially designed for insulator materials. It is mainly used to apply tensile loads to insulator materials at the same time in high and low temperature cyclic environments to test their thermal engine performance. The box structure is customized according to the size of the specimen, using high-quality stainless steel liner and thermal insulation material, and is equipped with precision temperature control and mechanical tensile system.
1. The box adopts imported SUS304B stainless steel liner and ultra-fine Glass thermal insulation cotton, and the door adopts double-decked silicone rubber sealing, which has good thermal insulation sealing performance. 2. Equipped with Mechanical Property Tension Device, it can apply and maintain the tensile load within the specified range in high and low temperature cycles. 3. The heating system adopts a porcelain frame nickel-chromium wire electric heater, which has little thermal inertia, long service life and stable control. 4. The refrigeration system adopts the French "Taikang" fully enclosed Compressor and high-quality parts imported from many countries, and uses environmentally friendly refrigerants for reliable operation. 5. The control system uses a 7-inch true-color LCD touch screen temperature controller for accurate control and stable long-term operation. 6. Equipped with a complete safety protection system, including multiple electrical protections, independent over-temperature protectors, and system interlocking devices. 7. The air supply method is the upper air supply and the lower air return, with good temperature uniformity.
The device heats or cools the air in the working room through the evaporator, electric heater and fan in the air conditioning cabinet to achieve a temperature cycle of -40 ° C to 80 ° C. The temperature sensor monitors the trend temperature, and the control system adjusts the PID according to the set parameters to ensure the temperature stability. At the same time, the mechanical stretching device applies and maintains a constant tensile load on the insulator specimen placed in the working room to simulate its stress state in a harsh temperature environment to evaluate its performance.
Thermal and Mechanical Properties of Insulator Materials
GB／T 22708-2008
1. Place the equipment in an environment with room temperature below 28 ° C, well ventilated and 80 cm space around the machine. 2. Connect the AC380V three-phase four-wire power supply to ensure voltage stability. 3. Set the required temperature cycle program, time, and tensile load parameters through a 7-inch touchscreen temperature controller. 4. Install the insulator specimen onto a dedicated mechanical stretching tooling. 5. Start the circulating fan, and after the system self-checks, start the refrigeration/heating system and mechanical stretching device to start the test. 6. During the test, temperature, load, and other parameters are monitored through the control system. 7. After the test reaches the set time, the equipment automatically stops or ends according to the program, and the specimen is taken out.
The operating environment temperature of the equipment should be between 5 ° C and 28 ° C, and the average temperature within 24 hours should be less than or equal to 28 ° C. • The environment humidity should be ≤ 85%. • It is necessary to ensure that the power supply is AC380V (+/- 10%) three-phase four-wire system and well grounded. • No items can be placed within 80 cm of the front, rear, left and right of the equipment to ensure ventilated heat dissipation. • Before starting, confirm that the circulating fan is started normally, otherwise the refrigeration and heating system will not work. • Regularly check the effectiveness of system safety protection devices (e.g. over-temperature protectors). • The refrigeration system is equipped with high and low pressure protection, please do not adjust it at will during operation. • Please pay attention to the various fault indicators on the equipment when operating.
