1. Materials
(1) The laboratory adopts PVC polyvinyl chloride board, and the durable temperature reaches 60 ℃
(2) The sealing cover of the laboratory adopts PVC impact-resistant board
(3) The reagent supplement bottle adopts a hidden water level meter, which is easy to clean and not easy to break.
⑷ The saturated air barrel is made of SUS#304 stainless steel high pressure barrel, which has the best insulation effect
⑸ The laboratory basket adopts a plane indexing frame, and the angle can be adjusted arbitrarily. The fog and fog on all sides are completely consistent, and the number of test pieces is large.
2. According to GB/T10587-2006 specifications, settable constant temperature control
(1) Salt spray test:
① Laboratory: 35℃ ±1℃
② Saturated air bucket: 47℃ ±1℃
⑵ Corrosion resistance test:
① Laboratory: 50℃ ±1℃
② Saturated air bucket: 63℃ ±1℃
3. Air supply system: the air pressure is 1kg/cm², which can be adjusted in two stages
The first is to roughly adjust 2-2.5kg/cm² with the function of filtering oil and water
The second is a finely adjusted 1kg/cm² ¼PT pressure gauge
Fourth, the spray method
⑴ Adopt Bernut's principle to absorb salt water and then atomize, the degree of atomization is uniform, and there is no phenomenon of blocking crystallization, which can ensure the standard of continuous testing
(2) Nozzle: It is made of special glass nozzle, which can adjust the size of the spray volume and the spray angle
(3) Spray volume: adjustable 1-2ml 80cm²/hr (average volume for 16 hours)
5. Heating series
The direct heating method is adopted, the heating speed is fast and the standby time is reduced. When the temperature reaches ON/OFF, the switching temperature is accurate and the power consumption is low (the electric heating tube is a highly corrosion-resistant titanium alloy product)
6. Control system
⑴ Laboratory temperature controller 0-99.9℃, dual digital display with P.I.D automatic calculation, control error ±0.3℃
⑵ Saturated air barrel temperature controller 0-99.9℃, dual digital display with P.I.D automatic calculation, control error ±0.3℃
⑶ heating tank liquid expansion safety temperature controller 0-120 ℃
⑷ Saturated air barrel liquid expansion safety temperature controller 0-120℃
⑸ Digital display time controller 0.1s-9990hr
⑹ Timer 0-9990hr
⑺ Rocker illuminated latch switch, which can be latched continuously for 20,000 times
⑻ 150 type, 240 type, 350 type are manual flip cover; 500 type, 770 type are air pressure
Automatic opening and closing of cylinder
Seven, water system
Adopt automatic water replenishment system, automatic replenishment when the water level is too low
