Ⅰ. Introduction:

This series of products are salt spray corrosion test equipment for artificial simulation of marine climate, which can be used for accelerated corrosion performance change test after surface treatment of electrical equipment, metal materials and various materials, including anti-corrosion treatment of coatings, electroplating, inorganic and organic coatings, anodic treatment and antirust oil. It is also one of the "three defenses" (damp heat, salt spray, mold) test equipment for artificial climate environment, and an important test equipment for studying the adaptability and reliability of various environments in machinery, defense industry, light industry electronics, instruments and other industries, and can also be used for vinegar salt spray test.

Ⅱ.  Main Technical Parameters: 

The FQY series salt spray test box is tested by atomizing compressed gas (one or more spray devices are installed in the room according to the size of the test volume to meet the test needs). The function of the spray device is to use the high-pressure air supplied by air source system to eject from the nozzle at a high, so that a high-speed airflow appears at the outlet of the air jet pipe on the nozzle, and a negative pressure is generated above the suction pipe of the nozzle. Under the action of peristaltic pump, According to a certain flow rate, it is sent to the nozzle, wheere it is smashed into fog by high-speed airflow. The smashed fine fog floats out from the spray nozzle and diffuses into the test space of the studio, forming a diffuse state,naturally falling, and carrying out salt spray corrosion test.

（1）Box body part

The inner and outer liners of the salt spray test box are malded by imported glass fiber reinforced plastic, which has the advantages of light weight, corrosion resistance, high strength, no leakage, smooth surface and easy cleaning.(Note：The inner container of titanium plate salt fog box is made of titanium alloy, and the outer shell is painted with 316 stainless steel.)

The water seal prevents fog from overflowing (the titanium plate salt fog box is sealed with a sealing ring), and the bottom is a heating device, which adopts the heating mode of separated channels, so that the temperature of the studio is fast, the temperature uniformity is high, the stability is good and the accuracy is accurate.

The top cover of the salt fog box is molded with imported plastic plates, and the top angle is designed to be 120 degrees, so as to prevent the condensed water in the box from directly dripping on the sample (the top cover of the titanium plate salt fog box is also made of titanium alloy.)

The spray mode is tower spray or wall-mounted spray tower spray. The tower spray tower is placed in the bottom center of the studio, and the wall-mounted spray tower is hung on the upper right side of the studio. The spray material is made of Shi Ying glass, and the sprayed fog particles are fine and non-crystalline, and the salt spray is naturally deposited and evenly distributed.

The control system of the test box is placed at the upper right of the box, which is convenient for users to operate.

The Internal

The inner and outer liners of the salt spray test box are molded by imported glass fiber reinforced plastic, which has the advantages of light weight, corrosion resistance, high strength, no leakage, smooth surface and easy cleaning.

Water seal (rubber seal) prevents salt spray from overflowing, and the bottom is a heating device, which adopts the heating mode of separated channels, so that the temperature of the studio is fast, the temperature uniformity is high, the stability is good and the accuracy is accurate.

The top cover of the salt fog box is molded with imported plastic plate, and the top angle is designed to be 120 degrees, so that the condensed water in the box does not directly drip on the sample.

The spraying method adopts a two-fluid nozzle, which is placed at the bottom center or back wall of the studio. The sprayed fog particles are fine and amorphous, and the salt spray is naturally deposited and evenly distributed.

（2）The External

Fog collector: collect the spray amount of each test, with 50ml for each high scale.

Isolation tank: use the principle of water seal to avoid salt spray leakage.

Saturated air bucket: placed at the bottom of the control box, made of transparent acrylic. Its function is that the air is heated and humidified by the bucket, and then sprayed to the nozzle after the air reaches saturated humidity. Air enters from the bottom, and is fully wetted and preheated by the liquid in the saturated barrel, so that the spraying effect is better and it is not easy to crystallize and block the nozzle.

Test cover: a roof-type perspective cover with an oblique angle of 120 degrees, which is used to cover and combine the test box.

Pressure regulating valve: manually adjust the inlet pressure and spray pressure. The inlet pressure is controlled at 0.4mPa；; The spray pressure is controlled at 0.07~0.17mPa.

(The above pressure has been adjusted before leaving the factory, so the user does not need to adjust it in general).

Exhaust pipe: 50mm diameter pipeline.

Drainage pipe: 16mm drainage pipe, from which waste water is discharged.

 (3) Control system

Test chamber temperature controller: controls the temperature of the test chamber and sets it according to the standard temperature.

Saturated air barrel temperature controller: controls the temperature of saturated air barrel.

Timer: adjustable for 1 min ~ 9999.99 hr. The time required for the test can be set at will, and it will stop automatically at last, with an automatic zeroing device.

Heating of saturated barrel: the water level in saturated barrel must be higher than the lowest water level, otherwise the equipment will be damaged.

Power switch: Delixi cam switch controls the total power supply of the whole machine.
 

 (4) Pneumatic system

It is composed of air compressor, pressure regulating valve, pressure gauge, oil and water filter, electromagnetic valve, spray generator and pipeline. The function of the air source system is to continuously supply the pressure and clean air needed for spraying in the test chamber. After the ambient air is compressed to form high pressure, it enters the air saturator for preheating after oil-water separation, filtration and pressure regulation. The secondary pressure-reducing valve is connected to the nozzle, so that the nozzle pressure is always kept in a stable state, and the salt spray test is ensured to be carried out smoothly.

 (5) Salt replenishment system and spray mechanism

It consists of salt water tank, high temperature resistant and corrosion resistant silicone hose, nozzle, etc. The high-pressure airflow generates negative pressure at the suction nozzle through the nozzle, and the stroke siphon action sucks the salt water in the salt water tank into the nozzle. After being treated by a spray tower, it is sprayed out of the studio.


 (6) Saturated bucket water intake system

 Pure water or deionized water is added into the air saturator, and the alarm stops when the water level is in place. If there is pure water under pressure in the laboratory, the water inlet pipe can be directly connected to the pure water supply pipe. If there is no pure water under pressure in the laboratory, the water inlet pipe can be put into the deionized water tank or the pure water tank, and there is a booster pump in the equipment to automatically pump water into the saturated barrel. Do not directly connect to tap water!
