Current 23a Environmental Test Room Simulation High Altitude Low Pressure Test Chamber
Simulated high altitude low pressure test chamber (plateau environmental test chamber) | |
Box specification | 1, inner size: 800 (width) × 800 (deep) × 800 (height) mm 2, the outer dimensions are about: 1100 (width) × 1050 (deep) × 1680 (height) mm + 150mm casters; subject to the real thing; 3. Control panel: The control panel is located at the lower part of the machine (as shown in the figure); 4, open the door: single door from right to left; 5, compartment: inside the second layer, the bottom 50mm first layer, the above is divided into two layers, with two stencils; 6, can be window: the door with a window, specifications 350 * 350mm; 7. The sealing material is: high temperature resistant silicone strip; 8. The structure of the box is: the upper part is the product room, and the lower part is the electric control box and vacuum pump installation; 9. Vacuum pump installation method: the vacuum pump is installed in the lower part of the machine; 10. The inner box material is: high temperature resistant SUS304# stainless steel industrial board, the thickness of the steel plate is 5.0mm, and the treatment is vacuumed without deformation; 11. The outer box is made of: 1.2mm thick cold-rolled steel plate, and the outer surface of the steel plate is treated with double-sided paint (white); 12, insulation material: fiber rock wool, good insulation performance, thickness 100mm; 13. Equipment use environment: working environment temperature is 5 to 25 °C, working environment humidity is 35% to 75%; 14. The movable caster and adjustable fixed foot cup are installed at the bottom of the machine. |
Temperature control system | 1. The temperature controller is a digital display instrument (Taiwan Taisong instrument), single-point temperature control, automatic calculation, PV/SV simultaneous display, button setting; 2, timing function: 0-9999 hours / min / sec, warm to the timing, time to stop heating, and alarm prompts; 3. The temperature sensing line is (K) type; 4, the output is 3-32V; 5. The current controller is: SSR solid state relay; 6. Heating method: heat radiation with three sides heating; (left, right, and bottom sides of the inner box wall) 7. The heating element is: stainless steel high temperature resistant heating tube; 8, temperature range: normal temperature +15 ~ 100 °C adjustable; 9, instrument control accuracy: ± 0.5 ° C; 10. Instrument accuracy display: 0.1 °C; 11, the temperature deviation inside the box: ± 6 ° C. (no vacuum test). |
Seal and vacuum display | 1. This machine adopts high-density silicone sealing strip to seal at the door, and the sealing performance of the whole machine is good; 2. Use Panasonic digital display vacuum gauge to display the vacuum inside the box; Negative pressure display pressure gauge 3. The vacuum sensor is: automatic air pressure sensing; 4. Vacuum range: 0.0KPa to -100.0KPa; 5, vacuum pressure leakage rate: about 1.0KPa per hour; 6. The vacuum control mode is: automatic control, reaching the upper limit set value stop, lower than the lower limit start, and thus circulating to maintain the optimal low pressure state; 7. Pressure display mode: For relative display, if the test vacuum is 70.0KPa, the standard air pressure is 101.3KPa-70.0KPa=31.3KPa, and the vacuum gauge is set to -31.3KPa. The set data is pumped away. Pressure, other parameters are calculated in the same way; 8. Vacuum pump configuration: one XD-20 vacuum pump, voltage 220V, power 0.9KW; 9, vacuum pump exhaust device, need to be exhausted to the outside (your company to handle it). |
Over temperature and circuit protection system | 1. Over-temperature protection system: independent over-temperature protection device, when the over-temperature protection set temperature is exceeded, the heating supply is automatically stopped, thus protecting the safety of products and machines; 2, circuit protection system: phase sequence protection, ground protection, overload protection, circuit breakers, etc.. |
machine power supply | 1, voltage 380V/50Hz three-phase five-wire system; 2, current 23A 3, power 6.0KW 4, except for rice cooker power |
Monitoring System | 1. Make two 220V/3KW sockets in the box and use them for the rice cooker on behalf of the electricity; 2. The rice cooker power supply line monitors the voltage, current and power (the monitoring table is shown in the figure). |
