The voice signal of acquisition amplification is transmitted to voice signal analysis and diagnosis system through data acquisition device, to collected reciprocal pump liquid
Movement parts and fluid leakage voice signal carry out analyzing and diagnosing in power end, this is to the timely identification of reciprocating pump working condition and failure
Diagnosis has stronger directive significance and application value to guarantee that reciprocating pump works normally.Here it is background of the invention and
Meaning.
Summary of the invention:
The object of the present invention is to provide the leakages of the reciprocal fluid end pump valve of a set of new monitoring, piston motion and fluid to be issued
Abnormal sound device, device have the characteristics that installation it is simple, using it is convenient, measure it is accurate, invent provided by measurement dress
It sets and is leaked using the sound transducer test pump valve, piston motion and the fluid that are mounted in special local sound insulation sound collection end
Sound, microphone and preamplifier built in the sound transducer in local sound insulation sound collection end, to collected pump valve,
Piston motion sound and fluid leakage voice signal are transmitted to the sound in computer after data acquisition device is handled after amplifying
Sound signal analysis and diagnosis system carries out signal processing.The device not only can be by other components such as itself the engines of reciprocating pump
Movement sound isolation, and the other equipment movement sound of environmental noise and production scene can be isolated, to guarantee to adopt
The voice signal that collects is clear and diagnosis it is accurate.
In order to solve the above technical problems, a kind of monitoring reciprocating pump hydraulic-end pump valve of the present invention, piston motion and fluid are let out
The device for leaking issued abnormal sound includes pump valve valve deck in objective body reciprocating pump hydraulic-end and by microphone, preposition amplification
Local sound insulation collection terminal, the data of device, polyester fiber soundproof plate, plasterboard, sound-proof material, deadening felt, outlet and shell composition
Four part of vasculum and voice signal analysis and diagnosis system.Mainly there are following characteristics:
Local sound insulation sound collection end have many advantages, such as good soundproof effect, light weight, can be portable, easy for installation, work
When do not influence the normal work of reciprocating-pump valve；Its bottom is using open, by external noise and local sound insulation sound collection end
Internal cavities are isolated, and so as to effectively completely cut off the interference of ambient noise, while allowing the sound of reciprocating pump hydraulic-end
Sound effectively comes into local sound insulation sound collection end and is effectively acquired by sound transducer, both ensure that soundproof effect or not in this way
Influence the acquisition of target sound signal.
The present apparatus is by by the effective of sound signal collecting end and data acquisition device and voice signal analysis and diagnosis system
Combination realizes direct effective acquisition of reciprocating pump hydraulic-end pump valve, piston motion and fluid leakage sound, to reciprocal failure of pump
Pattern-recognition provides correct voice data foundation, is obtained by the voice signal analysis and diagnosis system of independent development and is correctly examined
