Most easy to wear and most weak link is bolt, and bolt will directly affect the safe operation of equipment once damaging, more serious
It is possible that causing destructive consequence.In the situation of bolt failure, usually happens is that thread root and screw rod fracture.To sky
When the maintenance down of air supply heat pump, since the factors such as maintenance duration, detection device limit, air source heat pump bolt cannot be carried out
Disassembly is examined, and there are the bolts of crackle to detect and replace in time, so, can lose to the safe operation of subsequent unit
Stay serious hidden danger.
Eddy current effect refers to Faraday's electromagnetic induction law, when blocky conductor is placed in alternating magnetic field or in fixed magnetic field
When middle movement, induced current is generated in conductor, this electric current is closed in conductor.The vortex of conductor can also generate heat, such as
The resistivity of Tab phenolphthaleinum body is small, then the vortex generated is very strong, and the heat of generation is just very big.Infrared thermal imaging detection is to utilize infrared spy
It surveys device and optical imaging objective receives the infrared radiation energy distribution pattern reflection of measured target to the photosensitive member of infrared detector
On part, to obtain Infrared Thermogram, this thermography is corresponding with the heat distribution field of body surface.This technology is examined in equipment
It surveys aspect and has played its important role.Firstly, successful fault diagnosis, especially can moderately report out of order examine in advance
It is disconnected, apparent benefit will be generated；Secondly, fault diagnosis technology can produce huge booster action to maintenance of equipment, not only may be used
To greatly save human resources, moreover it is possible to traditional planned maintenance mode be upgraded to State Maintenance mode, or even to depot spare part
Way to manage will all generate active influence, industrial equipment detection effect and safe running performance can be effectively increased.
