Abstract
The utility model discloses an equipment fault detector which consists of a detecting head, a circuit board and an earphone. The utility model is characterized in that the detecting head is in a cylindrical shape; the periphery of the front end is provided with an entity shock resistant sleeve; the inner periphery of the front end is provided with a rubber sound insulation sleeve; a mike is arranged in the rubber sound insulation sleeve; the other end is provided with the circuit board; the mike is connected with the circuit board through a transmission wire; and the circuit board is connected with the earphone. The utility model realizes the effects of fast and accurately judging the internal fault of the equipment, can find the fault in the application of a motor, a pump and a valve in time, treat the fault in time, can eliminate the accidents fundamentally, and ensure the production safety of the oil field.
Description
One, technical field
The utility model relates to a kind of to the equipment failure detecting device in the equipment operation
Two, background technology
In the multi-purpose station production run process, self wearing and tearing of equipment such as motor, pump and valve commonly used, internal flow wash away erosion, the capital makes the equipment part gap big, produce phenomenons such as noise during work, in addition, solid impurities such as the part greasy filth iron rust that precipitates in the production accumulate in the gate inside groove, and these all very easily cause closing gate not tight.Can't in time make again and judge accurately and handle, and the race oil that causes, industrial accident such as metal run out very easily take place.Having become influences the big hidden danger that oilfield safety is produced.
Three, summary of the invention
The purpose of this utility model provides a kind of equipment failure detecting device, solves the problem that the equipment in using is detected, and finds that in time the fault on-call maintenance solves, and eliminates accident among rudiment.
The technical solution of the utility model realizes in the following manner:
The utility model is made up of detection head, circuit board and earphone, and it is cylindrical to it is characterized in that detection head is made as, and the leading section periphery is provided with essential anti-vibration sleeve, interior week is provided with the colloid barney, is provided with microphone in the colloid barney; The other end is provided with circuit board, by transmission line microphone is connected with circuit board, and circuit board connects with earphone.
The utility model realized judgment device internal fault problem quick and precisely, can in time find in motor, pump and the valve applications fault, in time handle, accident potential is eliminated among rudiment, guaranteed field produces safety.

Five, embodiment
For further disclosing the technical solution of the utility model, elaborate by embodiment below in conjunction with Figure of description:
The utility model is made up of detection head, circuit board and earphone, and it is cylindrical to it is characterized in that detection head is made as, and the leading section periphery is provided with essential anti-vibration sleeve 1, interior week is provided with colloid barney 2, is provided with microphone 3 in the colloid barney; The other end is provided with circuit board 6, by transmission line 5 microphone 3 is connected with circuit board 6, and circuit board connects with earphone EJ.
Structural principle is seen accompanying drawing 1, accompanying drawing 2
As shown in Figure 1, the utility model is made up of essential anti-vibration sleeve 1, colloid barney 2, microphone 3, metal hollow pipe 4, circuit board 6, earphone 7.Essence anti-vibration sleeve 1 is close to microphone 3, is installed in the front end of metal hollow pipe after wrapping up with the colloid barney, and the rear end is equipped with the electronic component case, circuit board and power switch is installed in it.Between connect by transmission line 5.
Design concept: as shown in Figure 2, between BG1 base stage and collector and connect electric capacity, solved and produce vibration in the circuit and cause the problem of uttering long and high-pitched sounds; In order to solve the problem of lower tone, microphone M adopts Electret condenser microphone
(sound-track engraving apparatus is used); Earphone EJ adopts high resistant earphone (200 ohm); 2.2K what resistance adopted is temperature compensating type; Triode BG1 adopts 3DG200C; BG3 adopts 3DK201; Install regulator potentiometer W (radio with) additional and solved the uncontrollable problem of volume.
Extraneous signal imports microphone M into through shockproof wooden unit, and electrochemical capacitor (10u) enters the BG1 base stage.Being directly coupled to complex pipe BG2, BG3 again after this signal amplifies further amplifies.Output to earphone from the earphone output plughole then.The fluid thorn leakage sound collection that utilizes wooden shock-proof block that device interior is produced because of pressure reduction, through microphone sound is amplified, pass to wiring board by transmission line, by sound intensifier sound being amplified the back in wiring board spreads out of by earphone, thereby allow the staff in time obtain the operation conditions of device interior, in time judge.
The utility model can some are faint sound amplify, thereby can judge in time, accurately gate The production phenomenon such as be not closed completely. Simultaneously, the principle of utilizing this device sound can be amplified can also be applied to In the detection of other equipment, play the effect of quick judgement.
