Box Structure
1) This equipment consists of a chamber body, temperature control system, vacuum control system, electrical control system, safety protection system, etc
2) The box is made of mechanical equipment, with smooth lines and exquisite craftsmanship, presenting a beautiful and elegant appearance
3) The material of the inner box is 3mm thick high-quality stainless steel plate that has been polished and reinforced with shin bones. The outer box is made of high-quality cold-rolled steel plate with a thickness of 1.2mm, which has undergone special surface treatment and electrostatic spraying.
4) High performance sealing materials and unique silicone rubber sealing structure are used between the door and the door frame, with good sealing and aging resistance.
5) The vacuum system consists of domestically produced high-quality oil-free pumps, stainless steel vacuum valves, stainless steel connecting pipes, and digital vacuum pressure gauges.
6) There is a stainless steel movable sample rack inside the box, which is detachable and easy to clean.
Temperature control system:
Adopting the Japanese "Fuji" temperature controller, the product adopts a PID fuzzy logic processing controller to quickly reach the set value and operate more accurately and stably. LCD display, clear and intuitive indication. Overtemperature alarm and automatic cut-off of heating power supply. It can simplify the complex experimental process and truly achieve automatic control and operation.
Rapid cooling system: The equipment is equipped with an air cooling system and a water cooling system, which can quickly cool the temperature of the inner box from 500 degrees to ambient temperature. Usage conditions: Water source: cooling water 4l/DN15 (supplied by a chiller).
Vacuum control system:
The vacuum drying oven uses digital technology from analog engineering to control the vacuum degree, and "manual control" has long been a thing of the past. Do you still think that in the 21st century, manual lever operated valves can accurately control the vacuum degree? The vacuum drying oven uses digital technology from analog engineering to control the vacuum degree, and the fully automatic digital display control of the vacuum degree through an electromagnetic valve provides you with more accurate and effective vacuum degree control. Through the panel, the vacuum degree can be adjusted from 1Pa to 100000Pa, with an adjustable accuracy of 1Pa. The sensor uses a resistive silicon tube pressure sensor to ensure stable pressure values, which are not affected by airflow and transmit stable pressure values to the LED display screen of the vacuum controller.
Pressure measurement and display: Shanghai "Vico" digital pressure gauge, digital pressure sensor.
Control panel: an operational control platform for human-machine dialogue. Equipped with pressure display instruments, vacuum and nitrogen filling solenoid valve switches, etc
Pressure control mode: automatic control: pressure value can be set, manual control: vacuum pump keeps pumping and stops manually when needed
Vortex oil-free dry pump: Model: WXG-4A, pumping capacity: 4L/S. Brand: Shenke Instrument.
Electromagnetic valve: Shanghai "Ximat" brand vacuum electromagnetic valve is used, which automatically switches to the atmospheric pipeline when the vacuum pipeline is cut off
electrical control system
