Box structure
|
Structure |
Adopting an integral left-right structure: The equipment is composed of the test chamber body, air duct system, heating system, electrical control, etc. The heater is located in the air duct and does not directly radiate the test sample. The air duct circulation is used to ensure uniform temperature in the working room. The control panel and instruments are in the upper left part of the box with a reasonable structure and a beautiful appearance. Ventilation structure, non-vacuum filtration type. |
|
Shell material |
Cold-rolled steel plate is processed into shape, the surface is pickled and phosphated and then electrostatically sprayed (gray white) |
|
Endosome material |
SUS304# stainless steel plate, full welding process. |
|
Insulation material |
The insulation layer is filled with rock wool boards. The outside of the box liner and between the liner and the outer shell are laid with asbestos boards for heat insulation. The door and box are sealed with asbestos ropes. |
|
Gate |
Single door, the seal between the door and the box is made of asbestos rope. |
|
Exhaust device |
There is an exhaust hole device on the box, which can manually adjust the exhaust volume. Glass float flow meter. |
|
Partition |
3 layers, adjustable up and down |
|
Partition load-bearing |
20kg |
|
Casters |
Movable casters are installed at the bottom of the box to facilitate the movement of the equipment. |
System composition
|
Control method |
Forced internal circulation ventilation, the control system controls the output of the heater according to the set temperature point through the PID automatic calculation output result, and finally achieves a dynamic balance. |
|
Air circulation device |
Air duct circulation and external long-axis stainless steel centrifugal fan, the motor is located at the bottom of the box |
|
Heating method |
1. Adopt nickel-chromium alloy electric heater and PID adjustment 2. Executive element: SSR solid state relay |
Measurement and control system
|
Sensor |
K type thermocouple temperature measurement |
|
Temperature controller |
It adopts 30-segment Japanese "conductive" programmable high-precision digital display instrument, which can directly input, display and control temperature; it has PID parameter self-tuning function; the display resolution is 0.1℃; thus ensuring the high control quality of the entire temperature system |
|
Switch control |
The blower switch and the heating switch are logically controlled respectively. When the door is opened, the fan is turned off. If the fan is not turned on, the heating will not run. |
|
Mainly perform electrical appliances |
"Schneider" AC contactor, "Omron" relay |
|
Timer |
A timer is installed, and when a scheduled shutdown is required, the timing time control can be set |
|
Power control |
Sino-US joint venture "Lonning" solid state relay, zero-crossing trigger power adjustment technology, reliable control, no noise, no grid pollution |
|
Independent over-temperature protection |
Studio independent over-temperature protection, sound and light alarm |
|
How the system operates |
Constant operation, program operation |
Security protection function
1) Reliable grounding protection device;
2) Leakage/circuit break protection;
3) Heater short circuit protection;
4) The studio has independent over-temperature and sound and light alarms;
