Production of domestic thermal shock testing machine

Introduction to the structure of insulator thermal shock testing machine

　　Thermal shock testing machine for insulatorsThe structure is an upper and lower structure, with the upper end being the high-temperature air zone and the lower end being the cold water zone. The upper and lower ends adopt a mechanical transmission structure.

Technical parameters of insulator thermal shock testing machine

1. The internal dimensions of the high-temperature zone shall not be less than IW450 × IH450 × ID450mm; The internal dimensions of the cold water zone shall not be smaller than those of the high temperature zone, and shall ensure that the high temperature gas pressure generated by the sample will not cause cracking or deformation of the cold water zone box;

2. The temperature control range in the high-temperature zone is+20 ℃ to+200 ℃, with a temperature fluctuation of ≤± 0.5 ℃, a temperature deviation of ≤± 2 ℃, and a temperature uniformity of ≤ 2 ℃;

3. Temperature rise time, under no load and no heating conditions, RT~+200 ℃, within 50 minutes;

4. Exterior material: High quality cold-rolled steel plate with spray coating treatment, plate thickness not less than 1.0mm;

5. Interior material: high-quality stainless steel plate (SUS 304 2B CP grinding processing), with a plate thickness of not less than 1.0mm;

6. Box thickness: ≥ T100mm;

7. Thermal insulation material: high thermal insulation ultra-fine glass wool;

8. Door: equipped with high-temperature transparent glass, with a window size of not less than 250 * 250mm; 8. Air supply fan: single suction multi blade stainless steel axial fan, AC220V，180W；

9. Heater: Nickel chromium alloy heater, AC220V，1KW；

10. Circulation mode: forced hot air circulation, horizontal laminar flow mode;

11. Temperature regulation method: automatic adjustment of heating output power, PID adjustment, using imported control instruments;

12. Sensor: High precision K-type thermocouple;

13. Working mode: Automatic comparison between high and low temperature zones, automatically adjusting to the specified temperature for insulator thermal shock. The tester heats up and maintains the temperature according to the specified temperature and heating rate. After maintaining the specified time, the high-temperature zone bottom plate is automatically opened. There is a mechanical mechanism that automatically sends the sample into the cold water zone. The cold water zone valve plate opens and actively discharges water vapor. After the sample cools down, press the button to operate and the sample is taken out of the tester.
