Most pumps can operate from 450 to 3 600 cpm 7 5 to 60 hz depending on site pumping requirements available horsepower drive and gearing.
Vibration sensors for pumps.
Configurable to warn or stop the pump.
Physical characteristics such as temperature rating size and connector orientation are also considerations.
The vibration sensor that is for the application will depend on the frequencies of interest and the type of pump being monitored.
An introduction to our sulzer sense condition monitoring.
13 vibration monitoring of pumps august 2012 wilcoxon sensing technologies proprietary.
A vacuum pump attached to this pump s input provided the means of controlling the input head of the test pump.
Vibration monitoring of pumps 2008 proprietary information underwater accelerometers 757 and 746 perfect for lower bowl bearing vibration readings usable on submerged pumps at depths up to 1500 feet 457 meters 757 corrosion resistant case and armor braid cable ensures longevity 757 biaxial sensor measures vibration in two directions.
Many facilities want to monitor pump vibration but do not want an expensive vibration program.
4 20 ma sensors output overall vibration levels so that maintenance professionals can take action on pumps that indicate abnormal or increasing vibration.
For vertical measurement sensors should be located on the motor and pump drive end bearings.
4 20 ma corresponding to 0 50 mm s 0 1 97 inch s.
The range of vibration sensors offered is wide as a vibration sensor has many different characteristics that may vary including measurement related factors such as frequency response sensitivity and accuracy.
Protects against harmful vibration.
When it comes to rotating assets such as fans blowers pumps cooling towers and other equipment powered by ac induction motors vibration analysis is an effective diagnostic tool.
How to choose vibration sensors for rotating equipment.
Hermetic sensors used for protection against pump cavitation recirculation and resonance.
This measures velocity mm sec peak or rms to detect unbalance and problems with structural rigidity and or foundation.
Mounted in the pump top.
For horizontal measurement vibration sensors should be mounted on the motor bearings and pump bearings.
There are dozens of different types of pumps and a seemingly endless list of applications but industrial accelerometers can often help the maintenance professional to diagnose sometimes tricky issues with pump operation.
The pump was brought up to speed at 359 rpm.
