The structure of the salt spray test box allows you to understand the salt spray box in one step
Outside of the salt spray test chamber:
Dry and wet bulb thermometer: read the temperature and humidity in the test chamber.
Metering barrel: collect the spray volume of each test, 50ml scale
Isolate the sink: Use the principle of water seal to avoid the leakage of salt mist.
Saturated air barrel: placed at the bottom of the control box, a closed type, made of SUS # 304 rust steel plate, its function is to heat and heat the air through this barrel, so that the air reaches saturation humidity and spray to the nozzle.
Saline replenishment bottle: automatically replenish the saline solution of the brine preheating tank.
Test cover: Roof-type oblique angle 100 bottom see-through cover, used to cover and integrate above the test room.
Pressure regulating valve: This valve is adjusted when the air pressure is too high or too low. (Test condition 1kg / cm2)
Pressure gauge: The pressure indicated by the pointer on this gauge is the pressure reached when the air reaches the nozzle through the temperature of the saturated air barrel. (Test condition 1kg / cm2)
Exhaust pipe: 11/2 "caliber pipeline: connect the drain pipe to drain the water to make the waste water discharge.
Water inlet: Replenish the water in the laboratory and the saturation tank to normal use.
Operation switch: illuminate the rocker to control the heating system of the laboratory heating tank and saturated air barrel.
Timer switch: illuminate the rocker type to control the power supply of the time controller.
The low water level warning light on the left, the water level of the heating tank is lower than the lower limit, then this light is on, and the electric operating system is cut off.
Low water level warning light on the right: when the water in the saturated bucket is at the lower limit, this light will be on and the operating system will be cut off.
Spray switch: illuminate the rocker type to control the spray system.
Demisting switch: Illuminated rocker type, control demisting system
Salt spray test chamber control system
Laboratory temperature control: It is to control the temperature of the laboratory, set according to the standard temperature and temperature, brine test 35 ℃. Corrosion resistance test 50 ℃
Saturated air barrel temperature controller: and control the temperature and temperature setting of saturated air barrel, brine test 47 ℃, corrosion resistance test 63 ℃
Timer: Adjustable 0.1-9999hr can consciously set the time required for the test, and automatically stops at the end.
Time counter: 0-99999hr accumulation of test time.
Salt water spray test: the temperature controller of the laboratory is set at 35 ℃, and the temperature controller of the heated water tank is set at 47 ℃ (40 ℃ -50 ℃)
Corrosion resistance test: The temperature controller of the laboratory is set at 50 ℃, and the water is heated
Temperature controller setting 65 ℃ (60 ℃ -70 ℃)
Test room over-temperature controller: When the temperature of the test room is too high, the heater power can be cut off to stop heating, and the PVC board (located in the control box) can be protected.
Pressure barrel over-temperature controller: When the temperature of the barrel is too high, the heater power can be cut off to stop heating, and the PVC board (located in the control box) can be protected.
Power switch: Illuminated rocker type to control the total power of the whole machine.
Salt spray laboratory interior
Spray tower: The built-in glass nozzle is placed inside the nozzle, and the spray is dispersed into the test interior through the cone disperser through the tower guide.
Spray regulator: adjust the spray volume, increase the spray volume to increase, lower the spray volume to reduce. The brine preheating tank is located at the bottom of the spray tower. The brine in this tank is injected into the preheating tank through the brine refilling bottle. The water level of the preheating tank is controlled by the float, which can automatically control the water level. Rubber plug control.
Collector: The amount of mist sprayed from the nozzle is free-falled in the 80cm2 funnel cup, and then flows into the measuring cup from the duct.
Wet bulb cup: L-shaped wet bulb cup is a container that uses humidity to create water.
Storage rack: This rack is made of plastic steel, so the weight of the concentrated point is not more than 2KG. If it is scattered, it can still be within 10KG. There are two rows of upper and lower round holes on both sides of the rack, which are used to insert the rack into the vertical plane at 15 degrees and 30 degrees.
Filter: It is used to filter the incoming substance from the salt. It is made of glass.
Heated water tank: This water tank is attached to the bottom of the test chamber and is used for heating water to keep the temperature of the test chamber stable. Its function is heating and heat preservation.
