Abstract
The utility model provides a noise mixing arrangement for slush pump failure diagnosis, relates to noise mixing arrangement. A noise mixing arrangement for slush pump failure diagnosis, including sensor (2) and data fusion ware (3), install on hydraulic cylinder (1) of slush pump sensor (2), and sensor (2) number of pass is according to line connection to data fusion ware (3), data fusion ware (3) include receiving module (31) and processing module (32), and the signal of sensor (2) passes through the data line and conveys to receiving module (31), and receiving module (31) send electric signal transition to processing module (32) for data signal, export the result after handle processing module (32). The utility model discloses can obtain the noise signal of each vibration source department well to confirm the running state of slush pump.
Description
Technical field
The utility model relates to noise mixing arrangement.
Background technique
Machinery has mechanical noise along with vibration and produces in running, this is actually the result that mechanical vibration cause ambient air medium to vibrate, these mechanical noises comprise the attitude information of the operation of abundant machinery, also contain the fault message that equipment runs simultaneously, fault diagnosis can be carried out by mechanical noise to equipment.
Traditional noise diagnostics method based on acoustic signal has: the position of the judgement source of students be responsible for by the auditory system of people and frequency, rough estimate equipment whether normal operation; Or by means of microphone amplifier-sound level meter, near-field scan measurement and surface vibration velocity analysis are carried out to machine, be used for finding the noise source of machine and main audible device, accurate diagnosis is carried out in recent years mainly through frequency analysis, noise source is identified by sonic probe method, because Acoustic Based Diagnosis technology has non-contact measurement, simple and easy to do, on-line measurement and do not need to increase quality on equipment and affect the advantages such as the operation of equipment, attracts attention.
In slurry pump, usually arrange 3 fluid cylinders, fluid end 3 fluid cylinders run simultaneously, and each fluid cylinder all sends noise, and the distance of each fluid cylinder of fluid end is very near, and interference fluid cylinder is very large to the fluid cylinder influence of noise needing to measure.And slurry pump working environment more complicated, also have a lot of miscellaneous equipment running noises under operating mode, be difficult to the running state directly being judged fluid cylinder by single-sensor data.
Summary of the invention
The purpose of this utility model is to provide a kind of noise mixing arrangement for slurry pump fault diagnosis merging noise.
The utility model for the technological scheme achieving the above object adopted is: a kind of noise mixing arrangement for slurry pump fault diagnosis, comprise sensor and data fusion device, sensor is arranged on the fluid cylinder of slurry pump, and sensor is connected to data fusion device by datawire; Data fusion device comprises receiving module and puocessing module, and the signal of sensor is sent to receiving module by datawire, and receiving module converts electrical signals to digital signal and sends puocessing module to, Output rusults after puocessing module process.
Further, described sensor setting is in fluid end of pump bottom head covers.
Further, described puocessing module comprises fusion comparison module, compares separation module, output module, storage module, the digital signal that receiving module transmits is after merging comparison module fusion ratio and comparatively processing, data after process are sent to and compare separation module process by fusion comparison module, relatively the data after separating treatment are sent to output module by separation module, and the data that process is separated are sent to storage module and store and be sent to outside machine by output module.
The utility model can obtain the noise signal at each vibration source place well, thus determines the running state of slurry pump.
Accompanying drawing explanation
Fig. 1 is the skeleton diagram of the utility model preferred embodiment.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
As shown in Figure 1, a kind of noise mixing arrangement for slurry pump fault diagnosis, comprises sensor 2 and data fusion device 3, and sensor 2 is arranged on the fluid cylinder 1 of slurry pump, and sensor 2 is connected to data fusion device 3 by datawire; Data fusion device 3 comprises receiving module 31 and puocessing module 32, and the signal of sensor 2 is sent to receiving module 31 by datawire, and receiving module 31 converts electrical signals to digital signal and sends puocessing module 32 to, and puocessing module 32 processes rear Output rusults.
Described puocessing module 32 comprises fusion comparison module 33, compares separation module 34, output module 35, storage module 36, the digital signal that receiving module 31 transmits is after merging comparison module 33 fusion ratio and comparatively processing, merge comparison module 33 data after process are sent to compare separation module 34 and process, relatively the data after separating treatment are sent to output module 35 by separation module 34, and the data that process is separated are sent to storage module 36 and store and be sent to outside machine and need the data place after processing by output module 35.
Described sensor 2 is arranged in fluid end of pump bottom head covers, and sensor 2 can receive fluid cylinder noise preferably.
The present embodiment places 3 noise transducer monitoring equipment noises in fluid end of pump three bottom head covers, gathers the noise waveform of three noise transducers simultaneously, is obtained the noise signal of field apparatus reality by data fusion device 3.The noise signal at each vibration source place can well be obtained by data fusion, thus determine the running state of slurry pump.
