Technique effect of the present utility model: a kind of touch screen type hydraulic and pneumatic test experience platform that the utility model provides, fault is interim random setting of teacher, and guilty culprit exists variation and uncertain, detachably replaceable, student can repeat, and improves learning efficiency.The forgone drawback of the simple theories of learning of the utility model, by Representative Faults Diagnosis, process and teach correct thinking, scientific approach and advanced experience, student can be combined theory and practice together, grasp hydraulic system fault analysis skill, by practical operation, get a real idea of and the skilled hydraulic technique of grasping.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein, 1, master control power module; 2, instrument module; 3, button module; 4, PLC Programmable Logic Controller module; 5, relay module; 6, fault diagnosis module.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Shown in Fig. 1, a kind of touch screen type hydraulic and pneumatic test experience platform, comprises master control power module 1, instrument module 2, button module 3, PLC Programmable Logic Controller module 4, relay module 5 and fault diagnosis module 6.The function that this six large basic module provides full security appliance to control, provides the control of flow, pressure, motor, main circuit.Described experiment table also comprises any one or any two or more combination of following Hydraulic Elements: hydraulic pressure valve, hydraulicdirectional control valve, hydraulic flow valves, hydraulic actuator, throttling valve, surplus valve, solenoid directional control valve, sequence valve, flow speed control valve, two-position four-way valve, three position four-way directional control valve, hydraulic pump, reduction valve, hydraulic cylinder and retaining valve.Each Hydraulic Elements are installed the hydraulic quick coupler of same model, by hydraulic quick coupler, are connected with pipeline.Various Hydraulic Elements indifference in appearance on experiment table.
The connected mode of each Hydraulic Elements adopts hydraulic quick coupler, and each joint is furnished with the retaining valve with self-locking structure.Like this, even if experimentation center tap does not connect and comes off, do not have pressure oil ejection yet.The polytetrafluoroethylsealed sealed circle of the inner installation of hydraulic quick coupler, can better guarantee sealing effectiveness.
Experimental configuration scheme can be configured according to specific requirement, also can increase components and parts and other control modes with the function of Enhancement test platform to experimental facilities.Experiment table also can increase the components and parts that same model hydraulic quick coupler is installed, can be compatible to the components and parts experiment table that the later stage is newly-increased.
Experimental loop can be used machinery control, traditional Control, the advanced various control technology such as the automatic control of PLC.PLC Programmable Logic Controller module 4 can with PC communication, realized electric automatization control, can online programming monitoring and fault detect, can use PC and PLC to carry out deep secondary development etc. to hydraulic control system.
Experiment table electrical control is comprised of various template, can meet all kinds of control requirements, between each functional module, is used in combination line, simple, safety, reliable, control multiple functional.Fault diagnosis module 6 adopts remote control mode setting, disguised strong, can repeat.As optimal way, described button module 3 adopts touch screen type, can further optimize result of use.
The utility model can be commonly used the fault diagnosis experiment of Hydraulic Elements, as hydraulic pressure valve fault diagnosis and processing, hydraulicdirectional control valve Diagnosis and Analysis, hydraulic actuator fault diagnosis and processing etc.The utility model also can carry out electromechanics, the experiment of hydrostatic control class, as the common fault diagnosis of hydraulic pump and processing, PLC control common fault diagnosis and processing, electrical equipment control common fault diagnosis and processing etc.The utility model also can provide the dynamic simulation demo of 20 many kinds of liquid hydraulic circuit and control, can in computing machine, control the action of experimental loop, and can see clearly the principle with different colours demonstration hydraulic circuit oil circuit, make student's study more intuitively and understand experiment content.
Concrete application of the present utility model is as follows:
(1) fault setting; Teacher is contained in out of order hydraulic pressure valve, hydraulicdirectional control valve on experiment table in advance, and requires student to detect guilty culprit.
