I. structure and characteristics

1. The inner and outer bile of the salt spray test box are made of high quality high-temperature resistant plastic plates welded by high temperature molding, which have the advantages of light weight, corrosion resistance, high strength, no permeability, smooth surface and easy cleaning.

2, the water seal form so that the salt mist does not overflow, the bottom tank steam heating, so that the studio heating quickly, the temperature distribution is uniform. The top cover of the salt spray box is made of imported transparent plastic board by welding at high temperature and designed to be the best top Angle, so that the condensed water in the box will not drop directly on the sample.

3. The spray system adopts tower spray, which is placed in the left center of the studio. The material of the nozzle is made of quartz glass, and the spray particles are fine without crystallization.

4. The control system of the test box is placed on the right side of the box, which is convenient for the user to operate. The panel is equipped with a general power switch, a spray switch, two PID self-tuning numerical control instruments, and a device running time accumulator.

5. The lid and body of the box in the studio adopt active pneumatic support bar, which is more convenient to open.

Ii. Inside the laboratory

1. Spray tower or (baffle type) : the built-in glass sprinkler head is placed inside the nozzle, and the spray is guided by the tower tube and then dispersed by cone type or (baffle type) evenly into the laboratory.

2. Spray regulator: adjust the amount of spray and increase the amount of spray by increasing the tapered disperser or baffle on the spray tower. The brine preheating tank is located at the bottom of the spray tower. The brine preheating tank is injected into the preheating tank through the brine replenishment tank. The water level of the preheating tank is controlled by a float ball, and the water level can be automatically controlled.

3. Collector: the amount of falling fog ejected by the nozzle is in a free fall in the 80cm2 funnel cup, and then flows from the catheter to the measuring cup.

4, shelving: this frame is made of plastic steel, so the weight of the concentration point to not more than 2kg for the limit, such as scattered placement can still bear less than 10kg, shelving on both sides of the upper and lower two rows of circular holes, is placed in a vertical bar 15 degrees, 30 degrees Angle.

5. Heating sink: the sink is attached to the bottom of the laboratory, which is used for filling water and heating to keep the temperature of the laboratory stable.

6. Wet bulb cup: l-shaped wet bulb cup is a container for water using humidity.

7, shelf: this frame is made of plastic steel, so the weight of the concentration point below more than 2Kg for the limit, such as scattered placement can still bear less than 10Kg, shelf on both sides of the top and bottom three rows of circular holes, is placed in a vertical bar 15 degrees,30 degrees Angle.

8. Filter: for filtering impurities in salt solution. Filter gauze should be changed regularly.

9. Heating tank: this tank is attached to the bottom of the test chamber, and is used for filling water and heating to keep the temperature of the laboratory stable. Its function is heating and heat preservation.


Iii. Detailed explanation of box materials:

1. The body of the testing machine is made of light gray PVC board with a thickness of 5mm and a durable temperature of 65℃. The structure is strong.

2) the laboratory cover is sealed with transparent acrylic shock resistant plate with thickness of 5mm.

3. Concealing all-in-one refilling bottle, easy to clean and easy to operate.

4. Pressure air drum SUS#304 stainless steel high pressure drum insulation effect is the best.

All measures adopted plane dividing type test sample, adjust the Angle can be arbitrary, uniform fell all around the fog, fog completely consistent, the test results are accurate, the test sample quantity.


Iv. Technical basis

According to JIS, ASTM, CNS, GB standard parameter operation Settings.

(1) brine spray test; NSS, ACSS.

Laboratory: 35℃±1℃.

Pressure air tank: 47℃±1℃.

2) corrosion resistance test: CASS.

Laboratory: 50℃±1℃.

Pressure air drum: 63℃±1℃.


V. air supply system:

The air pressure is 1Kg/cm2 in two stages. The first section is roughly adjusted 2Kg/cm2, using imported air filter, with drainage function. The second section is for precision adjustment of 1Kg/cm2, 1/4 pressure gauge, showing precision and accuracy.

1. Spray method:

(1) benoit principle to absorb salt water and then atomize, atomization degree is uniform, no blocking crystal phenomenon, to ensure continuous test.

2. The nozzle is made of toughened glass, which can adjust the spray amount and spray Angle.

3. Adjustable spray volume (ml/80cm2/h) The measuring cylinder is installed with built-in type, the appearance is beautiful and tidy, the observation is convenient, the instrument installation space is reduced.

2. Heating system:

Adopt the direct heating mode, the heating speed is fast to reduce the standby time, when the temperature arrives, automatically switch the constant temperature state, the temperature is accurate, less power consumption. Pure titanium heat pipe, acid and alkali corrosion resistance, long service life.

3. Control system:

(1) the laboratory, pressure barrel are adopted LCD dual number temperature display controller, with microcomputer automatic calculation function, control error ±1.0℃ circuit board by moisture-proof and anti-corrosion treatment, high precision, long life.

2. The laboratory heating tank adopts liquid expansion safety temperature controller 0~120℃

3. Programmable time controller for LCD digital display and power failure memory function 0.1s ~9999h

4. Integrator 0~99.99h

And relay

㈥ become warped plate with lamp switch, can work continuously 25000 times.

4. Water adding system:

Two kinds of water adding systems are adopted, automatic and manual. The pressure tank and laboratory water level are replenished automatically or manually

Anti-dehydration and ultra-high temperature damage instrument.

5. Defogging system:

When the machine stops, remove the salt spray in the test box to prevent the corrosive gas from flowing out and damaging other precision instruments in the laboratory.


Vi. Safety protection device:

1. when the water level is low, the power will be cut off automatically and the safety warning light will be on.

2. When overheated, automatically cut off the power supply of the heater, and the safety warning light device will light up and display.

3. When the water level is low, the safety warning device shall light up and display.

(4) electric leakage protection function to prevent personal injury and instrument failure caused by electric leakage or short circuit of the circuit.
