3. Average evenness: + / - 3.5%
4. The heating rate, room temperature to 400 ℃ is less than 100 minutes
5. Pressure range: atmospheric pressure ~ 20.0kPa
6. Depressurization rate: atmospheric pressure ~ 20.0 kPa time is no more than 40min
7. Pressure recovery rate: 10 kPa/min (adjustable)
8. Pressure error:
A. 40 kPa plus or minus 2.0 kPa
B. 4kPa pressure <40kPa + or - 5% kPa
c
9. Temperature deviation of temperature/pressure comprehensive test:
A. when 10 kPa plus or minus 3.0 ℃ or higher
B. 4 kpa pressure or less < 10 kpa plus or minus 7.0 ℃
C. 4.0 kPa or less plus or minus 10.0 ℃
10. Wind speed: no more than 1.7m/s
12. Complete machine noise: no more than 80db
13. Power source: ac 380V/50Hz three-phase four-wire system
Ii. Structure and material configuration:
1. The pressure on the material: cold rolled plate steel polyester orange paint spraying, use external pressure type enclosure structure, the overall bearing strength is greater than 10 t / ㎡
2. Inner gallbladder: stainless steel, capable of bearing the charge of 20kg
3. Outer shell: cold-rolled thick steel plate polyester orange paint spraying
4. Big door: square door with high temperature resistant silicone rubber vacuum seal bar
5. Insulation layer: polyurethane foam + glass fiber, with thickness of 100mm
6. Observation window: 1, vacuum coating and frost proof, high-strength and pressure-resistant toughened glass observation window, size (width)300 x (height)300mm
7. Box body: 5 3/8 internal screw holes are opened on the upper plane of the box body, so that the product external thread can be screwed into 2cm depth
8. The charging interface is determined by the user
Iii. Heating system
1.Heating component: armored stainless steel plate type electric heater
2.Installation: evenly distributed between the pressure tank body and the stainless steel liner
3.Control mode: SRR contactless control mode
Circulation system:
1. Stainless steel lengthened shaft motor, centrifugal stainless steel fan blade
2.Rear air duct of the workshop, forced circulation air supply
3. Multistage diaphragm type air heat exchanger
V. pressure system:
Control system
1. Control method:
BTC balanced temperature control system, fully digital PID self-tuning regulation, no contact with thyristor trigger, so that the heat added to the system is equal to the amount of heat loss, without the expert function of parameter debugging by users. 
2. Sensor: armored Pt100 1
Vii. Safety and protection measures
1. Safe and reliable earthing protection device; 
2. Under-voltage power supply and lack of phase protection
3. Independent studio over-temperature protection
Heater short circuit/overload protection
5. Air blast motor overload protection
