A kind of gearbox oil-channel detection system
The utility model relates to gear case technical field, is specially a kind of gearbox oil-channel detection system.
As everyone knows, in gear case, the quality of the quality of lubricating oil has extremely important impact to the running status of gear case and serviceable life.Oil product inspection adopts fixed cycle sampling mostly, and send laboratory to test, experimentally the assay of room determines whether to change oil.Adopt the state of degree that this kind of mode can be certain being followed the tracks of oil product, if but gear case generation inordinate wear, be but difficult to find, by the time during next round of visits, perhaps gear case there occurs the damage of serious unrepairable.
Also there are at present some manufacturers that oil product is installed on gear case and detect pick-up unit, by oil product information being sent to producer during network implementation.But gear case is when occurring abnormal, should hard stop or downrating, existing system can't realize.Being integrated in master control system by oil product detection system as seen, is very necessary.
Utility model content
Utility model object: provide a kind of gearbox oil-channel detection system, to solve the problems of the technologies described above.
Technical scheme: the utility model is achieved through the following technical solutions:
A kind of gearbox oil-channel detection system, comprises oil pipe, some sensors, signal pickup assembly, signal processing apparatus, main control PLC, warning device and direct supply; Described oil pipe is provided with some sensors; Described some sensors successively by information collecting device and signal processing apparatus by signal transmission to main control PLC; Described main control PLC is also connected with warning device; Described some sensors, signal pickup assembly, signal processing apparatus, main control PLC and warning device are by direct supply centrally connected power supply.
The communication interface of described some sensors and signal pickup assembly is RS-485, and the communication interface of described signal pickup assembly and signal processing apparatus is RS-485, and the communication interface of described signal processing apparatus and main control PLC is RS-232.
Described some sensors can be respectively: wear particle sensor, grease viscosity sensor, fluid moisture transducer and contamination level of oil liquid sensor.
The beneficial effect of employing technique scheme is:
1. adopt and in real time gear case oil product is detected, and feedback data, manufacturer can have the very first time to grasp the running status of gear case oil product;
2. adopt general-purpose interface, sensor adopts modular combination mode, and convenient giving uses manufacturer to carry out personalized customization;
3. the utility model structure is simple, and cost is low, compares and is conducive to promoting on a large scale.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model;
1. oil pipes, 2. sensor, 3. signal pickup assembly, 4. signal processing apparatus, 5. main control PLC, 6. warning device, 7. direct supply in figure.
Below in conjunction with accompanying drawing, the utility model is described further;
As shown in Figure 1, the utility model provides a kind of gearbox oil-channel detection system, comprise oil pipe 1, four sensors 2, signal pickup assembly 3, signal processing apparatus 4, main control PLC 5, warning device 6 and direct supplys 7, described oil pipe 1 is provided with four sensors, 2, four sensors 2 to be respectively: wear particle sensor, grease viscosity sensor, fluid moisture transducer and contamination level of oil liquid sensor; Described four sensors 2 successively by information collecting device 3 and signal processing apparatus 4 by signal transmission to main control PLC 5; Described main control PLC 5 is also connected with warning device 6; Described four sensors 2, signal pickup assembly 3, signal processing apparatus 4, main control PLC 5 and warning device 6 are by direct supply 7 centrally connected power supply.Described some sensors 2 are RS-485 with the communication interface of signal pickup assembly 3; Described signal pickup assembly 3 is RS-485 with the communication interface of signal processing apparatus 4; Described signal processing apparatus 4 is RS-232 with the communication interface of main control PLC 5, and signal transmission is stable, reliable.
Introduce use installment state of the present utility model below.
Four sensors 2 are respectively: data are passed to signal pickup assembly 3 by RS-485 interface by the particle information of lubricating oil, grease viscosity information, fluid water cut information and contamination level of oil liquid information by wear particle sensor, grease viscosity sensor, fluid moisture transducer and contamination level of oil liquid sensor; Signal pickup assembly 3 transfers data to signal processing apparatus 4 by RS-485, data are carried out process through signal processing apparatus 4, change after be transferred to main control PLC 5 by RS-232 again; If main control PLC 5 is adjusted by the operation of Logic judgment to whole system. certain index exceeds required value, and master control will send alarm command to warning device 6.Above action is all that all parts runs execution automatically, does not need manual operation, and the running status of monitoring and control gear case, effectively reduces and avoid the generation of gearbox fault in real time.
