Description
Technical field
The utility model relates to machinery and drags the trouble free service technical field, is specifically related to a kind of oil pumper gear-box lubricating oil low oil level warning device.
Background technology
When oil pumper is worked in recovering the oil and produce in the oil field, wheel box is damaged if low oil level appears in the interior lubricating oil of its wheel box.At present; Only lean on artificial to the inspection of oil pumper gear-box lubricating oil position to the pasta view mode; This type test mode wastes time and energy and is difficult for the generation of discovery wheel box petrol starvation in time, thereby causes wheel box to damage, and causes unnecessary loss and influence to produce to country.
The utility model content
The purpose of the utility model is exactly the defective that exists to prior art, and a kind of oil pumper gear-box lubricating oil low oil level warning device is provided.
Its technical scheme is: comprise power supply, fuel level sensor, triode, resistance, relay, alarming horn, signal lamp.The positive pole of power supply is connected with an end of resistance, an end of relay and an end of relay contact; The other end of relay contact is connected with an end of alarming horn and an end of signal lamp; The other end of resistance is connected with an end of fuel level sensor and the base stage of triode, and the collector of triode is connected with the other end of relay; The negative pole of power supply is connected with the emitter of the other end of fuel level sensor, triode, the other end of alarming horn and the other end of signal lamp; Said relay two ends are connected in parallel to diode.
Wherein, said fuel level sensor is installed in the oil pumper wheel box.Said alarming horn is high loudness siren loudspeaker.Said signal lamp is the flash caution lamp.
The utility model has advantage simple in structure, that making is easy, stable and reliable for performance compared with prior art.Can in time send sound and light alarm automatically when it can be reduced to normal value at the oil level of gear-box lubricating oil, the prompting staff notes, avoids causing unnecessary loss and the influence to producing to country.
Description of drawings
Fig. 1 is the circuit diagram of a kind of embodiment of the utility model.
Embodiment
With reference to Fig. 1, a kind of oil pumper gear-box lubricating oil low oil level warning device comprises power supply 1, fuel level sensor 2, triode 4, resistance 3, relay 5, alarming horn 8, signal lamp 9.The positive pole of power supply 1 is connected with an end of resistance 3, an end of relay 5 and an end of relay contact 7; The other end of relay contact 7 is connected with an end of alarming horn 8 and an end of signal lamp 9; The other end of resistance 3 is connected with an end of fuel level sensor 2 and the base stage of triode 4, and the collector of triode 4 is connected with the other end of relay 5; The negative pole of power supply 1 is connected with the other end of fuel level sensor 2, the emitter of triode 4, the other end of alarming horn 8 and the other end of signal lamp 9; Said relay 5 two ends are connected in parallel to diode 6.Wherein, said fuel level sensor 2 is installed in the oil pumper wheel box.Said alarming horn 8 is high loudness siren loudspeaker.Said signal lamp 9 is the flash caution lamp.
During operation, when oil pumper gear-box lubricating oil position just often, fuel level sensor 2 is equivalent to closure, triode 4 ends, relay 5 is failure to actuate, alarming horn 8 and signal lamp 9 are not all worked.When oil pumper gear-box lubricating oil position is reduced to safety value when following, triode 4 conducting immediately, the power supply of alarming horn 8 and signal lamp 9 is opened in relay 5 actions, makes it send sound and light alarm.
