Fire detector cleaning is a highly specialized task, requiring the cleaning operation to be carried out under conditions close to its production environment, with dedicated cleaning equipment and comprehensive testing methods. The entire fire detector cleaning process includes several technological processes: preliminary inspection → disassembly → cleaning → drying → assembly → inspection → aging → finished product.
Currently, there are several technological methods for fire detector cleaning both internationally and domestically. The key equipment is the ultrasonic cleaner, and the ultrasonic pure water cleaning method is the most effective and efficient method. Due to environmental protection requirements, it has been widely promoted.
The principle of the ultrasonic pure water cleaning method is based on the combination of the cavitation effect of ultrasonic waves and the physicochemical action of pure water solvent. The process is as follows: hot soaking — ultrasonic — spraying — pure water ultrasonic — drying. The main equipment includes an ultrasonic cleaner, rinsing basket, rinsing tank, drying equipment, stainless steel workbench, specialized testing instrument, detector cleaning, smoke chamber, anti-static facilities, and pure water machine, etc.
