Description
Technical field
The utility model belongs to automatic electronic control technique field,, particularly a kind of water pump trouble-shooter.
Background technique
Water pump is that mechanical energy is turned to the pressure ability of its internal flow of flowing through and the fluid machinery of kinetic energy.When water pump normally moved, whole unit should be steady, and sound should be normal.If unit vibration is excessive or noise is arranged then the tendency of water pump fault often, in general, cause that the reason of water pump vibration has: rotor unbalance, pump shaft is crooked, bearing wear or destruction, coupling connects pin or stone bolt is loosening, and bush gap is excessive etc.The complex structure of water pump, moving parts is many, and excitation source is many, therefore the motion state of water pump each several part is monitored, relatively difficulty.The research work of water pump fault measuring device at present is also not really general, and general specialized water pump trouble-shooter also is not very general, normally some simple test instruments.The function of this type of detection device is simple, precision is low and be subject to various foeign elements influence, especially its very flexible, difficulty updates.
Summary of the invention
To defective or the deficiency that existing technology exists, the object of the present invention is to provide a kind of automaticity height, monitoring result water pump diagnosis apparatus accurately.
In order to realize above-mentioned technical assignment, the utility model adopts following technological scheme to be achieved:
A kind of trouble-shooter of water pump; It is characterized in that; Device comprises that first piezoelectric acceleration transducer, second piezoelectric acceleration transducer, the first electric vortex type displacement sensor, the second electric vortex type displacement sensor, the 3rd electric vortex type displacement sensor, signal conditioner, data collecting card and data processing server, said first piezoelectric acceleration transducer, second piezoelectric acceleration transducer, the first electric vortex type displacement sensor, the second electric vortex type displacement sensor and the 3rd electric vortex type displacement sensor are connected with signal conditioner respectively, and said signal conditioner, data collecting card and data processing server are connected successively.
The device of the utility model can be realized virtual instrument technique, traditional divided oscillation signal analysis method and the combination of modern analysis of vibration signal side, and then effectively improves the efficient and the accuracy of water pump fault analysis and diagnosis.
