Ventilation aging test machine

First, the implementation of standards: JB7444-1994 GB / T3512-2001 Second, the operation control system: 1. Heating system: fully independent system, stainless steel fin electric heater; heating and ventilation system is completely independent; 2. Control System: Imported LED Number . was P, I, D + S, S, R microcomputer integrated controller; 3. ventilation control instruments automatic control panel equipped with ventilation control surface display and stop the display operation; 4. box at the top with a ventilation outlet, pre-adjustable ventilation outlet size; 5. circulatory system: high temperature low noise dedicated motor, axial fan; 6. Safety protection system: a leakage, short circuit, over-temperature, motor overheating, overload, over-current protection. First, the structural characteristics: 1 box with CNC machining, modeling nice, new and no reaction handle, easy to operate. 2. box inside and outside the gall bladder using imported high grade stainless steel (SUS304) or 304B welding mirror panel made of steel tank shell using A3 spray, increasing the appearance of texture and cleanliness. 3. The use of intelligent microcomputer controller with temperature protection program, and with the timing, temperature accurate and reliable. Ventilation time and frequency can be arbitrarily set. 4. There is a large observation window with bright lights to keep the box and the use of tempered glass, clear observation box condition at any time. 5. The hot air circulation system consists of continuous operation in high temperature fan and special duct, working room temperature uniformity. 6. The aging tank equipped with low-speed dial, press the test sample holder is mounted on a circular turntable suitable location. 7. cabinet insulation ultra-fine glass fiber cotton insulation, to avoid unnecessary energy loss. 8. The left side of the box with test hole with a diameter of 50mm, for external test power line or signal line. 9. The single-chamber door, using woven asbestos strip seal. 10. The bottom of the machine can be fixed with high quality PU wheels. Third, the product uses: ventilation aging chamber for detection of the sample after aging in air at high temperature and atmospheric pressure, and measured its performance and be compared with the unaged sample of performance to determine the temperature of products or components aging of the performance.
