Description
Technical field
The invention belongs to vertical shock mitigation system, be specifically related to a kind of dish spring vibroshock fault the cannot-harm-detection device.
Background technology
Dish spring vibroshock is the vitals in the vertical shock mitigation system.The structure of dish spring vibroshock is as shown in Figure 1, comprises big screw 1, O-ring seal 2, cover plate 3, dish reed 5, guide 6, overcoat 7 and clamping screw 8, and it is installed in the bottom of device, and residing working environment is very abominable.At ordinary times, dish spring vibroshock when running into the impact shock load, plays buffering, cushioning effect to these parts through the weight of parts in this device of support ring support; When this parts work, the effect that dish spring vibroshock will bear the HTHP Working medium gas; After this parts work was accomplished, dish spring vibroshock will bear the sea water immersion of long period, and when the cover system of certain device broke down, dish spring vibroshock will bear the effect of big hydrostatic force especially.Whether good whether vibroshock O-ring seal dish reed, in it soaked, whether the dish reed is intact, and the duty of spring bumper is had fundamental influence.Because dish spring vibroshock is mounted on the ship, check that dish spring vibroshock must at first disassemble from ship, decompose then and check that its troublesome poeration, workload are very big, and common ship person is difficult to carry out inspection.Therefore, to dish spring vibroshock dismantle, overhaul, generally all must be undertaken by the professional and technical personnel to the base.Adopt the method for this dismounting, overhaul, not only workload is big, and has a lot of fruitless labours because dismantle, overhaul be likely the parts that do not have fault.
Summary of the invention
The present invention will solve is the problem that existing dish spring vibroshock detection efficiency is low, need dismounting, troublesome poeration, provide a kind of detection efficiency high, need not to dismantle, dish spring vibroshock the cannot-harm-detection device and method of application thereof simple to operate.
Technical scheme of the present invention realizes with following method:
A kind of dish spring vibroshock the cannot-harm-detection device comprises analyser, and analyser connects signal and fits accent device and charge amplifier, and signal is fitted and transferred device to connect vibro-pickup, the hand hammer of charge amplifier connecting band dynamometer.
The method of testing of said dish spring vibroshock the cannot-harm-detection device is carried out in the following manner
(a) select trouble-free dish spring vibroshock, the signal vibro-pickup is fixed on the housing of dish spring vibroshock, knock the big screw on the dish spring vibroshock, use this standard signal of analyser analyzing stored a afterwards with the hand hammer of being with dynamometer;
(b) selection has the dish spring vibroshock of first fault mode; Described first fault mode is that O-ring seal damages, the interior water inlet of dish spring vibroshock; The signal vibro-pickup is fixed on the housing of dish spring vibroshock; Hand hammer with the band dynamometer knocks the big screw on the dish spring vibroshock, uses this fault-signal of analyser analyzing stored b afterwards;
(c) selection has the dish spring vibroshock of second fault mode; Described second fault mode is that the dish reed damages; The signal vibro-pickup is fixed on the housing of dish spring vibroshock, knocks the big screw on the dish spring vibroshock, use this fault-signal of analyser analyzing stored c afterwards with the hand hammer of being with dynamometer;
(d) select dish spring vibroshock to be measured, the signal vibro-pickup is fixed on the housing of dish spring vibroshock, knock the big screw on the dish spring vibroshock, use analyser analyzing stored measuring-signal d afterwards with the hand hammer of being with dynamometer;
(e) measuring-signal d and standard signal a are compared;
(f), measuring-signal d and fault-signal b or fault-signal c are compared if measuring-signal d is different with standard signal a.
The present invention need not disassemble dish spring vibroshock when detecting from ship, simple to operate, efficient is high, and does not need special technician.Through measurement of comparison signal d and standard signal a, fault-signal b, fault-signal c, can judge not only whether dish spring vibroshock is in normal duty, and which kind of fault mode the damage that can also judge dish spring vibroshock is.

Embodiment
As shown in Figure 2, dish spring vibroshock the cannot-harm-detection device of the present invention comprises analyser 13, and analyser 13 connects signal and fits accent device 12 and charge amplifier 11, and signal is fitted and transferred device 12 to connect vibro-pickup 10, the hand hammer 9 of charge amplifier 1 connecting band dynamometer.
Method of application of the present invention is carried out in the following manner
(a) select trouble-free dish spring vibroshock, signal vibro-pickup 10 is fixed on the housing 4 of dish spring vibroshock, knock the big screw 1 on the dish spring vibroshock, use this standard signal of analyser 13 analyzing stored a afterwards with the hand hammer 9 of being with dynamometer;
(b) select out of order dish spring vibroshock; Described fault mode is that O-ring seal 2 damages, the interior water inlet of dish spring vibroshock; Signal vibro-pickup 10 is fixed on the housing 4 of dish spring vibroshock; Hand hammer 9 with the band dynamometer knocks the big screw 1 on the dish spring vibroshock, uses this fault-signal of analyser 13 analyzing stored b afterwards;
(c) select out of order dish spring vibroshock; Described fault mode is that dish reed 5 damages; Signal vibro-pickup 10 is fixed on the housing 4 of dish spring vibroshock, knocks the big screw 1 on the dish spring vibroshock, use this fault-signal of analyser 13 analyzing stored c afterwards with the hand hammer 9 of being with dynamometer;
(d) select dish spring vibroshock to be measured, signal vibro-pickup 10 is fixed on the housing 4 of dish spring vibroshock, knock the big screw 1 on the dish spring vibroshock, use analyser 13 analyzing stored measuring-signal d afterwards with the hand hammer 9 of being with dynamometer;
(e) measuring-signal d and standard signal a are compared;
(f), measuring-signal d and fault-signal b or fault-signal c are compared if measuring-signal d is different with standard signal a.
Principle of work of the present invention is following: the hand hammer 9 with the band dynamometer knocks the big screw 1 on the dish spring vibroshock, and this percussion power is passed to dish spring 5 through feather key 6, and the response of dish spring 5 passes to vibro-pickup 10 through housing 4.The force signal of the hand hammer 9 of band dynamometer is passed to analyser 13 after amplifying through charge amplifier 11; Response signal on the vibro-pickup 10 passes to analyser 13 after fitting accent device 12 through signal, and analyser 13 is analyzed and storage after receiving force signal and response signal.
During use; At first selecting not have the dish spring vibroshock that damages measures; Storage standards signal a selects respectively to store corresponding failure signal c and d because of water inlet and dish reed 5 in O-ring seal 2 damages, the dish spring vibroshock damage the dish spring vibroshock of cisco unity malfunctions afterwards.When whether needs inspection dish spring vibroshock had fault, the big screw 1 of hand hammer 9 hammerings of employing dynamometer obtained the dynamic perfromance signal d of dish spring vibroshock.If measuring-signal d compares with standard signal a, not unusual, expression dish spring vibroshock is in normal operating conditions; If measuring-signal d compares with standard signal a and occurs unusually, expression dish spring vibroshock damages, and then need measuring-signal d and fault-signal b or c be compared.If measuring-signal d compares not unusual with fault-signal b, represent that then the source of damage is that seal 2 damages, the interior water inlet of spring bumper; If measuring-signal d compares not unusual with fault-signal c, represent that then the source of damage is that dish reed 5 damages.Utilize this principle just can carry out fault diagnosis through lossless detection method to dish spring vibroshock.
