Detailed description of the invention
For making the purpose of the present invention, technical scheme and advantage clearer, develop simultaneously referring to the drawings
Embodiment, is described in further detail the present invention.
Use " put prevention first, scheduled overhaul is main, and interim repairing is auxiliary " mode that the industry of factory is set
Standby safeguard so that operation expense is big and adds the reason of Safety Risk in Production and mainly has following
3 points:
First point, based on theoretical mistake.
Industrial equipment before the seventies in last century is safeguarded in theory, it is believed that industrial equipment is at the beginning of putting into operation
Phase will not break down, industrial equipment fault occur mainly due to the increase of service life cause old
Change causes, as it is shown in figure 1, Fig. 1 is the existing damage curve figure safeguarded in theory, wherein transverse axis is
Time, the longitudinal axis is fault.
But, after the seventies in last century, this safeguard that theory is by substantial amounts of experiment and research
Data are rejected, industrial equipment damage curve as shown in Figure 2 six kinds of current educational circles accreditation, permissible
Finding out, real industrial equipment damage curve wants complexity very compared with being thought in theory with the seventies
Many, and the theoretical curve shown in Fig. 1 can only reflect a kind of situation therein, wherein transverse axis is the time, vertical
Axle is fault.On city-level, the trouble or failure of most industry equipment is all random, unrelated with the time,
And safeguard the trouble or failure that may accelerate industrial equipment in some cases.
Therefore, the theory that " scheduled overhaul is main " follows, i.e. " industrial equipment will not be sent out in the gas storage that puts into operation
Raw fault, equipment fault is the aging theory caused caused due to the increase of service life " be
Basic mistake or incomplete.And the maintenance mode formulated based on this theory may result in a large amount of money
The waste in source and the biggest fault that may accelerate industrial equipment.
Second point, technical limitations.
In the industrial equipment maintenance process carrying out factory, some factories have realized that " prevention is in employing
Main, scheduled overhaul is main, and interim repairing is auxiliary " mode also exists the biggest defect, but due to technology
Ability is limited, and is difficult to improve.Such as power plants, a medium-sized power plants typically has two sets
Above can the generating set of independent operating, often overlap thousands of kinds of the industrial equipment of unit, the operating mode of every kind is former
Managing the most different, these thousands of kinds of industrial equipments also exist again mutual restriction and cooperate simultaneously, it is difficult to
Unified planning maintenance mode, if formulating suitably industry according to every or every kind industrial equipment own situation
Equipment control mode, required technological means and detection equipment, broad categories, various in style, calculate
Amount greatly, relies on manual record can not complete unified allocation of resources or integration work.
Further, from single industrial equipment fault diagnosis mode for, not Integration Mode the most effectively,
Still as a example by power plant, current industrial equipment attendant is typically only responsible for a kind of or class detection equipment
Use, such as infrared detection personnel be only capable of grasp infrared equipment using method and analyze main points,
Other detection meanss such as ultrasonic, vibration or fluid are had little understanding.But, a certain in factory
For the fault diagnosis of the industrial equipment run, only the multiple detection method of integrated use, just can have a pin
Property is judged whether there is fault, or trouble point is wherein.As a example by favourable turn class industrial equipment, have
The fault diagnosis mode of effect is: diagnostic analysis-judge whether vibration exceeding the standard, infrared analysis-judge whether office
Portion's superheating phenomenon, ultrasonic-to judge lubricant effect, oil analysis-judge bearing wear, and current of electric divides
Analyse-judging electrical fault problem, this is a primary fault diagnosis, for more complicated industry
Equipment or problem also need to introduce other more complicated fault diagnosis modes.In practical operation, due to
Industrial equipment attendant only grasps one or a class fault diagnosis mode, lack various diagnostic results or
The means that effectively integrate of information, and coordinate multiple industrial equipment attendant and concentrate certain industrial equipment is entered
Row judges the most difficult, so certain class industrial equipment usually only arranging the routine detection of routine, such as
Favourable turn industrial equipment is only carried out vibration values size detection, and the industrial equipment causing a lot of problem is the most wrong
It is mistakenly considered health, ultimately results in the generation that industrial equipment is shut down.Such as, the vibration of certain water pump does not exceed standard,
But bearing lubrication goes wrong, high oil temperature, but fail owing to only it having been carried out vibration detection
Pinpoint the problems, judge industrial device controls by accident, ultimately result in main shaft locking, burn bearing, cause unexpected stopping
Machine.
Thirdly, industrial equipment exceptional fault cannot be got rid of in time.
In real work, the failure cause of industrial equipment is more complicated, and this situation is for Large core
Industrial equipment the most frequent, the Turbo-generator Set of such as power plant, when asking of unconventional property occur
During topic, the manual analysis that need nonetheless remain for associated specialist to a great extent solves.But, expert is the most very
Difficulty rushes towards power plant in the very first time.If remotely diagnosed by network, due to the technology of communications
Limiting, also method can be put into practice the most efficiently, general by method transmission rumble spectrum pictures such as mails,
Or appoint that the peculiar file format utilizing certain software is transmitted by methods such as mails.These methods are equal
There is shortage of data in various degree, it is impossible to actual response site environment and reaction time are long, between personnel
It is combined with requirement, is unable to reach the target of remotely diagnosis completely.Substantially, expert can only be by number
According to substantially analyzing, it is impossible to specifically determine the fault of industrial equipment and solve problem, even diagnosis
Often far from each other with actual cause.

Significant wastage；Secondly, the maintenance theory of industrial equipment may certify that, some equipment after detachable maintaining,
Can promote fault rate on the contrary, for this industrial equipment, schedule maintenance causes unnecessary loss also on the contrary
Cause non-programmed halt.Additionally, schedule maintenance does not ensures that during twice overhaul or light maintenance, equipment
Can be with fault-free even running.During this period, in the face of industrial equipment catastrophic failure, need to rob temporarily
Repair.And rush to repair in default of planned temporarily, need dispatch extra attendant and produce extra dimension
Protect expense, delay the normal production run time, can't ensure that factory quickly resumes production, thus make
The economic loss of Cheng Geng great.
