For ease of narration, by taking the implementation of the diagnosis under level misaligns failure as an example, it is described in detail, remaining failure is examined Disconnected implementation is similar.

First according to research failure and fault degree, adjustment failure is realized part corresponding with failure in subsystem 6, is completed The reduced state of this diagnostic system is set.The present embodiment is with serviceable condition state as a comparison, and detailed process is as follows：

Measure the axially and radially centering data of first shaft coupling 211, the shuttling device in contrast driven member subsystem 3 The normal data area value of body 31, reviews and validate the data and is in normal range (NR).

Then, by adjusting or checking that drives subsystem 1, drive subsystem 2, driven member subsystem 3, load are encouraged The system and unit status of subsystem 7 are realized in subsystem 4, communication subsystem 5 and variable working condition, complete the state prison of reciprocating equipment Survey and the operation of fault diagnosis system prepares.Wherein, the detailed process of inspection can include：

First, drives subsystem 1, drive subsystem 2, driven member subsystem 3, load excitation subsystem 4, survey are verified Whether reliable connect between the part that control subsystem 5 and variable working condition are realized in subsystem 7, including during subsystem 7 is realized in variable working condition Pipeline, multi signal coding and cable connection of each interface to peripheral data preservation intercomputer in interface module 51.Check the One air admission unit 71, the second air admission unit 72, first exhaust unit 73, second exhaust unit 74, the 3rd exhaust unit 75 and Whether valve opening and closing is flexible in four exhaust units 76, and gives the first air inlet by PLC technology unit 52 in communication subsystem 5 Unit 71, the second air admission unit 72, first exhaust unit 73, second exhaust unit 74, the 3rd exhaust unit 75 and the 4th exhaust Inlet and outlet valve conveying open signal in unit 76 so that intake and exhaust valve is in opening.Check driven member The lubricating system in operating component in system 3, (" hand turning " refers to before unit is started, by manpower profit to hand turning Rotation axis system is rotated into several circles with instrument, is used to judge whether is the load (i.e. machinery or running part) that is driven by motor 11 There is stuck and resistance increase situation, so as to the startup load of motor 11 will not be made to become big and damage motor 11 (i.e. Burn out)) more than 5 weeks, it is determined that without clamping stagnation, having no abnormal sound；Manual pump oil simultaneously checks each oiling point to oily situation.

Then, the upper electrical switch in closure cabinet C, into the display of the PLC technology unit 52 in communication subsystem 5 Screen 5213 see motor steering whether with driven member subsystem 3 in the fuselage of shuttling device body 31 on identify rotation direction Unanimously.As no, the cable phase sequence in the terminal box in drives subsystem 1 on motor 11 need to be changed.

Make status monitoring and fault diagnosis system no-load running 3 minutes to confirm lubricating oil oil pressure, driven member subsystem Crosshead in system 3 is normal without overheat, each oiling spot lubrication.Shut down after 3 minutes, check again for confirming each oiling point note of lubricating oil Whether the crosshead in oily situation and driven member subsystem 3 had thermochromism.After normal, status monitoring is made again And fault diagnosis system no-load running, check the lubricating oil temperature of lubricating oil temperature sensor measurement.Driven when the value reaches During the temperature that the shuttling device body 31 in component subsystems 3 can be loaded, input target load size (corresponding pressure, flow, Temperature value, rotating speed, motor load etc.), by taking pressure loading as an example, communication subsystem 5 then sends reading instruction under current state Pressure, flow, temperature, rotating speed etc. the corresponding current signal of measured value, by computing, be converted into corresponding pressure, stream Amount, temperature, tachometer value, compare with corresponding arranges value.If the pressure at expulsion measured value of first exhaust unit 73 is less than instruction Arranges value, then diminished instruction, first from communication subsystem 5 to the opening and closing of the Pneumatic three-way ball valve 735 in first exhaust unit 73 The pressure of exhaust unit 73 is increased, until in the pressure limit of appreciation command value；Again as a example by increasing flow load, drive The velocity sensor 5201 in velocity measuring component 520 in subsystem 1 is carried out under the assistance of fluted disc 5202 to present speed Detection, by controlling cable transmission to communication subsystem 5, and is displayed in the interface of display screen 5213, and operator is by regulation The adjusting knob 5211 in speed adjusting part 521 in communication subsystem 5, makes system reach certain rotating speed.Observing and controlling subsystem 5 pressure, temperature, the tachometer value according to obtained by current admission pressure, temperature, speed probe of system, calculates current discharge capacity, observing and controlling Subsystem 5 compares current discharge capacity with command value, according to result of the comparison, is sent to the frequency converter 5212 in drives subsystem 1 Frequency shift is instructed, and improves rotating speed, or operator manually improves rotating speed, and corresponding flow is obtained in real time after improving rotating speed Calculate and being shown in display screen 5213, so that flow system flow is increased to needs load.

By taking regulation motor load as an example, in system work process, multi signal coding and interface module in communication subsystem 5 Current of electric interface and electric moter voltage interface and each sensor etc. detect remaining signal in 51, for calculating power of motor, with The power of motor load value of setting compares, or judges whether to reach for the power of motor value for being shown in display screen 5213 for operator To requirement of experiment.

Again as a example by adjusting excitation load, the course of work of the system excitation load regulation is illustrated：Operator is by display The load value size of input desired value in interface is loaded in screen 5213, and sends the load in reading instruction to load excitation subsystem 4 Current measured value is transmitted to communication subsystem 5, observing and controlling subsystem by the torque tester 421 in lotus detection components, torque tester 421 System 5 judges whether to need to increase or reduce current excitations load value according to return value and the comparative result of desired load value.Such as Need to increase or reduce, just send command adapted thereto to load Drive assembly 41, the magnetic powder brake in load Drive assembly 41 according to Gained signal produces correspondingly sized countertorque under the collective effect of support frame 416 and carrier.Internal system is protected in overload In the range of protection value set in protecting assembly 43, the process is quickly repeated, until precision model of the current load in system In enclosing.

Generation, the course of work of access for fault diagnosis desired signal, in the generation of torsional oscillation load and running, Torsional angle test probe 515, torsional angle measurement Error Compensation probe difference read test tooth in multi signal coding and interface module 51 Disk pulse, reaches communication subsystem 5, and communication subsystem 5 carries out the torsional oscillation that process sets again after error compensation according to set algorithm Module, is calculated as torsional oscillation value；Photoelectric sensor reads the code device signal being fixed on mounting bracket 514, by the algorithm for setting It is calculated as the torsional oscillation value of another signal.The value is stored in the database of communication subsystem 5, is shown in display screen 5213 pairs Answer on interface.By adjusting load Drive assembly 41, the magnetic powder brake 412 in load Drive assembly 41 exists according to gained signal The size of the excitation load of support frame 416 and carrier, realizes the generation of the torsional oscillation load signal of different-energy level.

Afterwards, operator's bonding apparatus current load, device status data and diagnostic purpose, determine data storage opportunity simultaneously Instruction data storage is sent, or data automatic access time interval is set, misaligning the failure of reduced state completing level examines Each signal value under the disconnected course of work must be enrolled, and can be stored in database.

Again by following process, measuring for the fault diagnosis data under fault case is carried out.First, system is adjusted, makes system Run under setting failure, setting load, measure signal, for diagnosis provides data.The course of work of adjustment can include：

First by making system-down in communication subsystem 5.The upper electricity in the cabinet C in drives subsystem 1 is disconnected afterwards Switch, makes system cut-off.The installation stud 83 that failure is realized in subsystem 6 is unclamped again, is unclamped drives subsystem 1 and is driven son System 3 installs stud 83, nut 84 by corresponding, and somewhere or a few places adjust the locking nut 85 in adjusting part 61, such as Need to realize that level is misaligned, by controlling the precession of adjusting bolt 813 at somewhere or a few places or screwing out length, as requested moment of torsion Tight to install stud 83, according to jiggering, axially and radially centering data judge that this misaligns whether data deviation score is needing model vertically It is such as no in enclosing, above-mentioned work is repeated, until in the range of needing, reaching the axially and radially level pair of first shaft coupling 211 The setting of middle failure；Such as need to realize that misaligning for vertical direction unclamps the installation stud that adjusting bolt 813 unclamps drives subsystem 1 Nut 84 on 83, unclamps the locking nut 85 in driven member subsystem 3, adjusts the adjusting bolt 813 of adjusting part 61 Or the quantity of increase and decrease adjust pad 704, according to jiggering, axially and radially centering data judge that this misaligns data deviation score vertically It is such as no whether in the range of needs, above-mentioned work is repeated, until in the range of needing, reaching the vertical of first shaft coupling 211 Direction misaligns the setting of failure.

For other class fail operation processes, failure in the above-mentioned course of work is realized into corresponding implementation in subsystem 6 Part carries out correspondence replacement, and remaining course of work is essentially identical, repeats no more, but the course of work being similar to is within protection.

Finally carry out generation, the course of work of access of fault diagnosis desired signal.So that process is more, under fault case As a example by the generation and access of torsional vibration signals, torsional angle test probe 515, torsional angle measurement error in multi signal coding and interface module 51 Compensation probe read test fluted disc pulse respectively, reaches communication subsystem 5, and communication subsystem 5 carries out error according to set algorithm Torsional oscillation value is calculated as after compensation by the torsional oscillation module of setting again；Photoelectric sensor reads the coding being fixed on mounting bracket 514 Device signal, the torsional oscillation value of another signal is calculated as by the algorithm for setting.The value is stored in the database with TT＆C system, It is shown on the correspondence of display screen 5213 interface.Carried by being encouraged to control unit 415 in setting or regulation load Drive assembly 41 Command signal is reached controller 414, the output phase induced current of controller 414, by amplifier by lotus desired value, control unit 415 413 are converted into the input current range size of magnetic powder brake 412, support frame 416 of the magnetic powder brake 412 in mechanical connection Reaction under, be input into corresponding torque load to the 3rd shaft coupling 221, at the same control unit 415 according to scan frequency read turn round The instantaneous torque value of square tester 421 is converted into same amount by programmed algorithm computing, is compared inside control unit, presses Corresponding adjust instruction is sent from trend controller 414 according to comparative result, and then the 3rd shaft coupling 221 receives different-energy level Torque load, this torque load is continuously generated, and the size of required torque load can be carried out according to required torsional oscillation value size, is reached To the excitation of the torsional vibration signals of different-energy level.The torsion that control unit 415 can bear always according to whole shafting weakness simultaneously Moment pole is limited, and sets safe load alarm and removal load value, when the instantaneous torque value of torque tester 421 reaches safe load alarm Produce alarm and send change zero load to controller 414 with removal load value and instruct, and then protect shafting not because special circumstances Overload and damage outside the plan.Current tester 422 tests the actual exciting current of magnetic powder brake 412, and current value is transmitted to Control unit 415, control unit 415 is compared according to the protective current value for setting with it, when current tester 422 is instantaneous When electric current exceeds protective current value, control unit 415 sends instruction so that the output current of controller 414 is zero, so that magnetic system The dynamic output torque load of device 412 is zero, and then realizes that shafting overloads under torque load second protects again.Overload protective device 431 can cut off circuit when electric current is more than setting value, and the current value is set greater than being equal to the guarantor of above-mentioned current tester 422 Shield current value, realizes, when the exciting current value of magnetic powder brake 412 reaches 431 setting value of overload protective device, making electric current moment Zero is reduced to, so that torque load moment is reduced to zero, and then the triple protection that shafting is overloaded under torque load is realized.Its He is picked up signal by respective sensor in communication subsystem 5.Operator's bonding apparatus current load, device status data and diagnosis Need, determine data storage opportunity and send instruction data storage, or data automatic access time interval is set.Multi signal Interface unit and respective sensor realize multi-signal, the measurement of signal of interest multi-method of system under the control of communication subsystem 5 With compare.The fault diagnosis signal admission that horizontal or vertical direction misaligns is completed, is stored in database.Can be with the number of reduced state According to be compared or exclusively carry out data processing and analysis etc. work.

Other class fail operation processes, corresponding implementation part enters during failure in the above-mentioned course of work is realized into subsystem 6 Row correspondence is replaced, and remaining course of work is essentially identical, repeats no more, but the course of work being similar to is in protection of the present utility model Within the scope of.
