Large salt spray test chamber

Introduction to Construction

1. Inside the laboratory

spray Tower: The built-in glass nozzle is placed inside the nozzle, and the spray is dispersed into the laboratory through the tower pipe approach and the conical disperser.

Spray regulator: adjust the size of spray volume, increase the spray volume and decrease the spray volume. 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 a brine replenishment bottle. The water level in the preheating tank is controlled by a float and can be automatically controlled. There is a drainage outlet for cleaning at the bottom of the tank controlled by a silicone plug.

harvest collection Device: The amount of mist sprayed by a nozzle, which falls in its own wayInside an 80cm funnel cup, it flows through a tube into a measuring cup.

wet ball Cup:The L-shaped wet bulb cup is a container that uses humidity to hold water.

place thing Rack: This rack is made of plastic steel, so the weight of the collection point should not exceedLimited to 2kg, if dispersed, it can still withstand up to 10kg. There are two rows of circular holes on both sides of the storage rack, which are used to place the storage rod at a vertical angle of 15 degrees and 30 degrees.

pass filter Filter: Used to filter impurities in salt solution, ensuring that the nozzle is not blocked by debris.

plus hot water Slot: This sink is attached to the bottom of the laboratory and is used to hold water, heat and maintain stable experimental temperature and humidity. Its function is heating and insulation.

2. Outside the laboratory

Dry wet bulb thermometer: Read the temperature and humidity inside the laboratory.

plan quantity Bucket: Collect the amount of spray for each test,50ml depiction

secret seal water Slot: Using the principle of water sealing to prevent salt spray leakage

full and empty qi Bucket: Placed at the bottom of the control box, usingMade of SUS # 304 stainless steel plate. Its function is that the air is heated and humidified by this barrel to make the air reach the saturation humidity and then to the nozzle spray.

salt water supplement charge Bottle: Automatic replenishment of salt solution in the salt preheating tank

try verify Cover: Roof style angled100 degree perspective cover, used to cover and integrate above the laboratory.

tune press Valve: When the air pressure is too high or too low, this valve adjusts the laboratory pressure (test conditions) based on the pressure gauge display1kg/cm2）。

press 力 Table: The pressure displayed by the pointer on this gauge is the pressure reached when the air is heated through a saturated air tank and transmitted to the nozzle (under test conditions)1kg/cm2）。

row qi Tube:The 21/2 "diameter pipeline, combined with this mist exhaust, should not have water accumulation outside, allowing the mist to be naturally discharged.

row water Tube:A 1/2 "diameter pipeline, combined with a drainage pipe and a water drainage ditch, is used to discharge its wastewater.

enter water 口： Automatically replenish the water in the laboratory and saturation tank to normal usage conditions.

3. Control system:

Laboratory temperature control: It is to control the temperature of the laboratory, set according to the standard temperature, and conduct salt water testing35 ℃, corrosion resistance test at 50 ℃.

Saturated air tank temperature controller: It controls the temperature of the saturated air tank and sets the temperature for saltwater testing47 ℃, corrosion resistance test at 63 ℃.

plan time Device: AdjustableThe required time for the experiment can be set arbitrarily from 0.1s to 99hr, and the machine will automatically stop at the end.

Heating water tank temperature controller: controls the water temperature of the heating water tank. This controller is designed to cooperate with laboratory temperature control. When there is a large difference in environmental temperature around the testing machine, it also needs to be adjusted accordingly. Its setting method is located in the control box.

Salt water spray test: the laboratory temperature controller is set to35 ℃, set the temperature controller of the heating water tank to 47 ℃ (40 ℃ -50 ℃).

Corrosion resistance test: The temperature controller in the laboratory is set to50 ℃, set the temperature controller of the heating water tank to 65 ℃ (60 ℃ -70 ℃).

Saturated air tank safety temperature controller: Saturated air tank safety protection device, temperature safety setting value higher than actual temperature5 ℃ (located inside the control box).

Power switch: Light up switch, controls the overall power supply of the entire machine.

Operation switch: Illuminate the lifting plate to control the heating system of the laboratory heating tank and saturated air tank.

timer switchIlluminate the lifting plate and control the power supply of the time controller.

Spray switch: light the warping plate to control the spray system.

Defogging switch: Illuminated lifting plate, controls the defogging system, and clears salt spray inside the box.

Overtemperature alarm light: The temperature of the heating tank exceeds65o， This light will turn on and the power will be cut off.

Low salt water alarm light: If the water level in the brine preheating tank is below the lower limit, this light will turn on and the operating system will be cut off.

End indicator light: When the required time for timing setting ends, this light will turn on and automatically stop the machine.

Left low water level alarm light: If the water level in the heating tank is below the lower limit, this light will turn on and the power will be cut off.

Right low water level alarm light: If the water level of the saturated tank is below the lower limit, this light will turn on and the operating system will be cut off.
