Salt spray filter performance detecting system and method

Abstract

The invention relates to a salt spray filter performance detecting system and a salt spray filter performance detecting method and belongs to the field of electric power protection equipment. The salt spray filter performance detecting system is characterized by comprising a water pump (17), an atomization spraying pipe (16), a variable frequency fan (1), a first air particle counter (9) and a second air particle counter (10), wherein the water pump (17) is arranged at the outer side of a salt spray generating box (4), the atomization spraying pipe (16) is arranged in the water pump, the variable frequency fan (1) is arranged between a first pipeline (2) and a second pipeline (14) and is used for generating salt spray and circulating air flows, and the first air particle counter (9) and the second air particle counter (10) are arranged at the inlet and outlet parts of a tested filter (12). Compared with the existing filter performance detecting system, the salt spray filter performance detecting system has salt spray particle generation and detection functions and has the characteristics that the structure is simple, the measurement precision is high, the detection is convenient, the maintenance quantity is low, and the like.

Description

Technical field [0001] The invention relates to a salt spray filter performance detection system and method, belonging to the technical field of electric power protection equipment. Background technique [0002] With the continuous deepening of human exploration of nature, the equipment and devices for offshore operations are increasing. According to data, 50% of the failure factors of electronic equipment in offshore operations are caused by the environment. Among them, temperature accounts for 40%, vibration accounts for 27%, damp heat accounts for 19%, sand and dust account for 5%, and salt spray accounts for 4%. It can be seen that the impact of salt spray ranks fifth among nearly 20 environmental factors, which is a damage that cannot be ignored sex factor. Sea salt spray directly affects the environmental adaptability and reliability of each production equipment, and shortens the life of the unit. Therefore, salt spray filters must be installed for devices and equipm...

Problems solved by technology

At present, there are many air filter performance testing methods in China. For example, patent ZL201110131006.9 proposes a self-cleaning salt spray treatment method, but it cannot be used for salt spray filter efficiency testing, and research on salt spray filter performance testing methods is still blank.
