Stötpulsmetoden är en tillståndsövervakningsmetod som SPM is an abbreviation for the Shock Pulse Method, which is a patented technique for using signals from rolling element bearings as the basis for efficient condition monitoring of machines. Instant evaluation of bearing condition is given in an easily understood green-yellow-red color scheme. The second frame shows the electric filter which passes a train of transients at 32 kHz. Jaw crusher monitoring with SPM HD Mining operations include a number of critical applications that may cause severe disruptions in the production process in case of malfunctions.

Vibration analysis and the Shock pulse method (SPM) is a technique for using signals from rotating rolling bearings as the basis for efficient condition monitoring of machines. From the innovation of the method in it has been further developed and broadened and is a worldwide accepted philosophy for condition monitoring of rolling bearings and machine maintenance. HD Order Tracking is approximately ten times better than traditional order tracking algorithms when RPM is not perfectly stable. The effect of rolling velocity on the signal is neutralized by entering rpm and shaft diameter as input data, with 'reasonable accuracy'.
This is a basic course Part of the original Shock Pulse Method (SPM), dBm/dBc is used to obtain a fast, easy, and reliable diagnosis of the operating condition of rolling element bearings. Features Fast, easy, and reliable diagnosis of bearing condition Easy-to-understand condition evaluation in green-yellow-red scales. The oil film depends on lubricant supply as well as alignment and load. SPM HD monitoring in the pulp and paper industry SPM Instrument has supplied condition monitoring solutions to the pulp and paper industry for many years. A shock pulse transducer reacts with a large amplitude oscillation to the weak shock pulses, because it is excited at its resonance frequency of 32 kHz.
The much acclaimed SPM SPM HD – High Definition Shock Pulse Method Features Technical description Case studies SPM HD SPM HD® is a patented further development of the Shock Pulse Method (SPM) used for a fast, easy, and reliable diagnosis of the operating condition of rolling element bearings. From the innovation of the method in it has been further developed and broadened and is a worldwide accepted philosophy for condition monitoring of rolling bearings and machine maintenance. Case studies.
SPM Instrument has 42 years Shock Pulse Monitoring also known as SPM is a patented technique of predictive maintenance by measuring vibration and shock pulses of bearing in motors and to identify their condition and operating life before the next overhaul procedure. It was introduced in and is now a known Condition Monitoring method for monitoring of machines like. In many cases, it is also possible to determine the nature of the damage cracked inner race with spalling all around, or a single crack, etc. The last frame shows the converted shock pulse signal from the bearing, now consisting of a rapid sequence of stronger electric pulses.
Method spm shock pulse
To measure Shock Pulse we use filtering combined with a special Accelerometer, which is designed with specific characteristics for Shock Pulse Measurements. If designed properly, this same accelerometer can be used to measure normal vibration signals as well. Step 1 - Amplification. SPM HD can be used to monitor applications in the 0. These shocks 'ring' the shock pulse transducer, which outputs electric pulses proportional to the shock magnitude. In many cases, it is also possible to determine the nature of the damage cracked inner race with spalling all around, or a single crack, etc.Av standard- och The shock pulse method was invented in the late s. In rolling element bearings, there is a phenomenon where electric waves, or elastic waves, or shock pulses, or impact signals, are generated. The amplitude of these impacts is determined by three different parameters. With order tracking, the frequency range always covers the symptoms of interest, regardless of the rotational speed of the machine. HD Order Tracking On machinery operating under variable speed, analysis with High Definition Order Tracking provides reliable data and crystal clear measuring results even when RPM varies significantly during the course of measurement.
Hittade 5 uppsatser innehållade orden The SPM HD Shock Pulse Monitoring is a further development of Shock Pulse Method (SPM); which can be used for easy, fast and reliable diagnosis of the operating condition of rolling. As a result, random signals are suppressed and repetitive signals enhanced. It represents the highest shock pulses found during the measuring cycle.
