Specific embodiment
A specific embodiment of the invention is made further detailed below against attached drawing by the description to optimum embodiment
Thin explanation.
As shown in Figure 1, 2, a kind of Hydraulic Elements detection platform, for detecting Hydraulic Elements: solenoid valve, oil cylinder etc..Including
Hydraulic power unit, electric-control system, valve island.By taking solenoid valve as an example, solenoid valve is a kind of Liquid valve, for being controlled according to control signal
The conducting of liquefaction liquid.Since maintenance needs are tested after damage, it is installed on valve island and is tested.Valve is arranged on island
Multiple installation stations, solenoid valve are mounted on installation station, and the liquid-inlet of solenoid valve, outlet are drawn.
The input interface of solenoid valves connects hydraulic power unit, and hydraulic power unit includes oil pump, fuel tank.Oil pump one end passes through pipeline
Fuel tank is connected, the other end of oil pump passes through the liquid-inlet end of the solenoid valve on pipeline connection valve island, when operation of oil pump, by postal
Oil liquid in case is gone out by the input port that oil pump is pumped to solenoid valve.
Hydrostatic sensor is arranged in the liquid outlet end of solenoid valve, for detecting oil liquid pressure signal, the liquid of solenoid valve
Delivery outlet connects the recycling fuel tank of experiment by pipeline, and when solenoid valve is opened, oil liquid understands access to recycling mailbox by fuel tank,
The oil pressure pressure signal of oil liquid is detected to judge the opening state signal of solenoid valve, successively judges whether solenoid valve is opened.Pressure
Force snesor is connect with PLC controller, and the pressure signal for will test is uploaded to PLC controller, and PLC controller carries out accordingly
Judge the action state of solenoid valve.
Electric-control system includes PLC controller, touch screen, timer, and touch screen, timer are all connected with PLC controller, PLC
Controller is calculated by timer from Hydraulic Elements control signal is issued to moving between the working signal for detecting Hydraulic Elements
Make the time.Since PLC controller timing issuing solenoid valve open signal, stop when receiving the pressure signal of pressure sensor
Only timing, this time are the actuation time of solenoid valve, and the actuation time of each solenoid valve carries out as the data of detection
Judgement.The work of oil pump, solenoid valve is exported the control of control signal by PLC controller.In the calculating action time, open first
Opening operation of oil pump makes oil liquid full of pipeline, then controls solenoid valve and first acts once, so that pipe full oil liquid, then at this time
The open and close of PLC controller loop control solenoid valve come obtain solenoid valve work whether corresponding control signal and each time
Whether the actuation time of control solenoid valve meets the requirements.
Pressure sensor is used to detect the oil liquid pressure signal of solenoid valve output port output, if Hydraulic Elements use oil cylinder
When, displacement sensor can be used accordingly, is signal using the displacement due to hydraulic action oil cylinder, be judge oil cylinder with this
No movement.
When detecting the working condition of solenoid valve, PLC controller deliberate action time threshold is greater than movement when actuation time
When time threshold, PLC controller controls alarm connected to it and issues alarm signal；Alarm signal is shown by touch screen simultaneously
Breath.At this time since the actuation time of detection is larger, delay length is unsatisfactory for requiring, so the solenoid valve after warning reminding maintenance is not
It meets the requirements.
In order to further detect, detection number can be set by touch screen into PLC controller, PLC controller control
Solenoid cycles on-off termination detection process when on-off number reaches the detection number of setting, in the detection process, PLC control
Device processed judges whether Hydraulic Elements are working properly and show result by touch screen according to the actuation time detected each time.If
Qualified in the action frequency of setting, actuation time is respectively less than actuation time threshold value, then illustrates that detection process is qualified, repairs
Solenoid valve afterwards is met the requirements, and can be used.When occurring actuation time in the detection process greater than time threshold, illustrate detecting
There is the actuation time of detection to be unsatisfactory for requiring in the process, needing not repaired could use.
By this platform simulation actual condition, remove the step of being installed to original equipment test from；Workload is saved, avoids stopping production
Loss, avoids hydraulic oil from wasting；The number of test is set in PLC controller, detection mouth detection builds pressure number, can evaluate valve
Group Reliability of Microprocessor.
The integrally disposed power supply conversion module of electric-control system is realized the conversion for power supply by voltage conversion chip, is exported more
Kind of voltage value, can meet the electromagnetism valve test of different voltages grade, for test valve group provide power supply (multiple voltage mode 24VDC,
110VAC, 220VAC etc.), settable valve group action frequency, operating frequency etc. can show that is detected builds pressure time by touch screen
Number.Hydraulic power unit: oil pressure is provided for test valve group, is equipped with adjustable pressure device, overflow mechanism etc.；Regulator is used for in pipeline
Oil liquid pressure be adjusted, meet different oil liquid pressure requirements.
The solenoid valve that valve island is tested needed for being used to install designs multiple groups installation position, every group of peace according to live solenoid valve situation
Filled solenoid valve can be corresponded to mouth extraction by dress position, be conducive to running of hydraulic power oil and detection.Valve island outlet can be according to test needs
Connect pressure switch, oil cylinder, plug etc..
In use, by after maintenance solenoid valve or other Hydraulic Elements cut-in valve islands, the island Bing Fa corresponding interface installation pressure
Power switch, oil cylinder, plug etc..Solenoid valve action request, starting test, hydraulic pump works, solenoid valve are set in electric-control system
It is acted according to sets requirement, pressure switch will test situation feedback into electric-control system, and the PLC controller of electric-control system is according to inspection
Action situation, actuation time of the solenoid valve of survey etc. judge whether the work of the electromagnetism after maintenance meets the requirements.
Obviously present invention specific implementation is not subject to the restrictions described above, as long as using method concept and skill of the invention
The improvement for the various unsubstantialities that art scheme carries out, it is within the scope of the present invention.
