Introduction of spray device of Standard Salt Spray Test Machine

The introduction of the spray device of the Standard Salt Spray Test Machine: The Standard Salt Spray Test Machine simulates the destruction of the cargo caused by the surrounding environment of the deep sea. Standard Salt Spray Test Machine is composed of shield, temperature raising system software, sprayer system software, defogging system software and whole process automatic control system. The Standard Salt Spray Test Machine is equipped with an advanced wall-mounted spray system. The spray tower is made of corrosion-resistant materials. It is small in size and easy to disassemble and clean. The spray angle of the atomizing nozzle can be adjusted.

 

The salt spray is micro-dispersed, moist and dense, and meets the requirements of relevant standards. After the salt spray is sprayed upwards, it settles naturally and distributes evenly. It will not be directly sprayed on the test piece, and the Bernut's principle is used to absorb salt water and then atomize.

 

Standard Salt Spray Test Machine has two spray modes, continuous and intermittent, which can be set

Filtering device: A sand filter is installed at the water outlet of the brine tank to ensure that the nozzles are clean and prevent clogging.

 

Nozzle: The nozzle is made of high-quality quartz glass, and the spray particles are small, and there is no crystallization in continuous work.

 

Spray pressure device: The test chamber is divided into two stages of pressure regulation, namely intake pressure regulation and spray pressure regulation. And equipped with oil-water separator.

 

Collection of salt spray sedimentation: The test chamber can be arbitrarily arranged with clean collectors according to the standard requirements, and the salt spray sedimentation rate is 1-2ml/80cm2·h.

 

Quick fog removal: The box is equipped with an independent program-controlled fan fog removal system, which can suck outside air into the test chamber and discharge the cabin gas to the outdoors. After the test, the residual salt mist in the air can be evacuated within 15 minutes.

 

Standard Salt Spray Test Machine sprayer system: It is a vertical column sprayer equipment. The design and composition of the sprayer equipment should be able to cause tiny and wet. Dense fog, the raw material of the sprayer equipment cannot be manifested with the anti-corrosion solution.

 

Anti-corrosion aqueous solution: The common salt in the Standard Salt Spray Test Machine test should be high-quality sodium oxide, and the total moisture content of environmental pollution should not exceed 0.3%. The concentration value of the salt solution must be (5±1)% (mass ratio) to prepare a solution that dissolves (5±1) parts of salt in 95 parts of pure water or double pure water.

 

pH value: When the temperature is (35±2)℃, the pH value of the solution must be within 6.5~7.2). In the standard test, the pH value should be maintained within this range. Under the necessary conditions to ensure the concentration value of sodium oxide, the pH value can be adjusted by igniting with hydrochloric acid or partial alkali.

 

Solve each newly configured solution to accurately and precisely measure the pH of the solution. Be sure to adjust the pH within the specified range.

 

Note: The solution after the sprayer cannot be reused multiple times.

 

Gas supply and demand balance: The gas entering the sprayer equipment should be reduced without all stains. Certain effective measures should be taken to reasonably make the relative humidity and temperature of the compressed air exceed the actual operating specifications. The standard air pressure should be suitable for fine fog and heavy fog.

 

In order to avoid salt build-up, it is strongly required that the air humidity at the nozzle be at least 58%. According to the automatic operation, the boiling water tower of the cyclone dust collector should be allowed to maintain for a long time, with very small bubbles and a temperature of at least 35 °C. The temperature should not be too high to prevent too much water from entering the natural environment test chamber, and should not exceed the required operating temperature.

 

The Standard Salt Spray Test Machine sprayer is a tower spray. The height of the sprayer can be adjusted according to its own requirements. After the sprayer is used, the compressed air of the sprayer should be used to remove impurities, such as the oil generated inside. , dust and other impurities. For the spray of the Standard Salt Spray Test Machine, its spray device is one of the keys, which can judge whether the test box is spraying smoothly.
