The difference of sand dust test box experiment procedure
The difference of the sand and dust test chamber experiment procedure is that the basic particle size and movement type of sand and dust are different. The tailorable contents of these test procedures are: test temperature, dust composition, test duration and wind speed.
Procedure 1 → Dust blowing: used to study the product's adaptability to the role of dust blowing (diameter ≤149um).
Procedure two → sand blowing: used to study the product's ability to adapt to sand blowing (diameter≤150um-850um).
Procedure 3 → Dust reduction: used to study the dust reduction (diameter ≤105um) in the covered or closed areas (such as offices, laboratories, storage rooms and tents) where there is almost no air flow and the dust can accumulate for a long time. Usually electrical equipment).
Dust reduction can also affect the heat dissipation of equipment that has accumulated dust on the top surface. Dust test equipment is also used to verify the quality of the air filter at the entrance of the air pollution sampler for outdoor use.
Purpose of sand and dust test chamber:
a) Small particle dust (diameter≤149μm) program. The purpose of this sand and dust test chamber is to evaluate the equipment's resistance to dust that may block openings, infiltration cracks, bearings and joints. This test is also used to evaluate the working efficiency of the filter.
b) Blow sand (diameter size 150μm ~ 850μm) program. The purpose of this sand and dust test chamber is to evaluate the ability of the equipment to store and work without reducing performance, efficiency, reliability, and maintainability under the influence of wear (abrasion) or blocking effects of large, sharp-edged sand particles.
application
This sand and dust test box is suitable for evaluating the adaptability of all mechanical, optical, electrical, electronic, electrochemical and electromechanical devices that may be exposed to dry, sand blowing, dust blowing or dust falling conditions.
