Military standard sulfur dioxide salt spray test chamberIntroduction to Structural Design

1, thisMilitary standard sulfur dioxide salt spray test chamberBeautiful appearance design, reasonable structure, smooth and natural lines. Both the inner and outer shells are made of flame-retardant high-quality materialsPPPlastic board, durable temperature greater than85At ℃, the joints between the boards are formed by milling and planing90The method of using a high temperature welding gun to melt plastic welding wire and fill it with a right angle is adopted. After cooling, the weld seam is firm, the joint of the entire box is flat, the box structure is compact, and the appearance is bright. Various auxiliary accessories and facilities are also made of corrosion-resistant materials.

2The material of the box cover is flame retardant and of high qualityPPThe board, with observation windows on both the front and rear sides, allows for external observation of the condition of the indoor specimen without affecting the test results. And the lid is designed to110The optimal vertex angle is set to prevent condensation generated during the test from dripping onto the sample and affecting the test results. The box cover and body are sealed with water to prevent salt spray from overflowing, which may affect the test results and corrode other equipment in the room, and may even cause harm to the test operators.

3The box cover is automatically opened by the cylinder (Taiwan, China Yadeke), which is convenient. Opening angle approximately80Degree, compressed air is used as the gas source, with a pressure of0.4Megapascals.

4Water tank (saltwater, pure water): adopts a hidden structure with a drainage valve, easy to clean.

5Saturated bucket: usingSUS316High grade stainless steel pipe welding, good resistance to high temperature and high pressure. Using the Henry's law, heating and humidification are applied, and the required humidity for the test chamber is provided

6The sample rack is designed according to national standardsOType andVType with two layers above and below15Degree and30Tilting can also be done using hooks.VType adoptedPPMaterial production,OThe bracket adopts stainless steel tube jacket with heat shrinkagePVCMembrane, high strength and corrosion resistance.

7The inner container is heated using dry heating method, ensuring uniform temperature.

8Bottom: Adopting4Only advanced universal casters, which can be fixed and adjusted horizontally.

9Gas cylinder cabinet: equipped with a sealed storage area2a8LThe anti-corrosion cabinet for steel cylinders has a regulating valve that can be adjusted externally, and the anti-corrosion cabinet is equipped with concentration monitoring alarms10Install and connect the exhaust gas treatment cabinet. Once the steel cylinder leaks, an alarm will be triggered to manually close the valve and automatically start the exhaust system.

11Exhaust gas treatment: The exhaust gas must undergo environmental protection treatment before being discharged into the atmosphere. A centrifugal anti-corrosion fan is used. After the test is interrupted, the exhaust system will pump the corrosive gas in the box to the filtration device of the activated carbon and soda ash adsorption exhaust gas treatment tank.

Military standard sulfur dioxide salt spray test chamberspray system

1Pneumatic spray mode, the air pressure is regulated in two stages: the first stage is the intake pressure, and the general regulation is0.2~0.3MPaThe second level is the spray pressure, to meet the latest standardsGB/T10125-2012Requirements for spray pressure (precision2pcs）The spray pressure gauge of this equipment adopts customized high-precision pressure gauge.

2The baffle type spray is used to hang at both ends of the working room; Specially made quartz glass nozzle, salt free crystallization, uniform diffusion of atomized fog and free sedimentation in the test chamber, the height of the spray can be adjusted to guide the salt fog, and the fog particles are small and naturally sedimentation;

3The spray gas passes through the oil-water separator to filter and stabilize the oil-water pressure, and then enters the saturation cylinder for preheating and humidification,Then it passes through the solenoid valve and pressure regulating valve to reach the nozzle

4The saltwater tank is a built-in hidden type with a large storage capacity

5Before atomization, the salt water is filtered through a sand core filter to prevent debris from blocking the nozzle

6Two standard fog collection funnels are placed in the laboratory and connected to the measuring cylinder outside the box through pipes to monitor the settling amount at any time
