Sep 29, 2009· Dan, In my experience this ( "3 hours later" in particular ) vibration pattern IS typical for a sleeve bearing which obviously has loose fit by design. The PV pattern is also typical reflecting friction modulation. Whether or not one can assess size ( bearing wear ) of the gap inside the bearing from seismic data is questionable, IMO.

Dec 08, 2014· simply multiply mass of machine to amplitude. Dear Mohandes. Thank you very much for your valuable comments. I want to know the formula for power consumption by vibrator. if static moment of a vibrator = 600 kg cm how to calculate the power. power = static moment x g x speed.
Jan 11, 2018· P = Number of poles installed in the machine. Calculation: Find the synchronous speed of 4 pole induction motor which operates at 60 Hz. Solution: η sync = 120 * 60 / 4 = 1800 r/min. Motor Slip. Slip of a motor can be found from the formula: s = (η sync-η m)/ η sync * 100. η sync = Speed of magnetic field. η m = Mechanical shaft speed
Nov 22, 2011· Perform a Visual Check of the Machine Foundation. The machine foundation plays a vital role in the vibration level of the installed equipment. A rigid and massive foundation ( Photo 1) is ideal, because it minimizes background vibration observed at the motor or other equipment. A massive foundation is less active, meaning it will limit the ...
Jun 26, 2009· Yes, 6Hz (5.96 exactly) is belt frequency (while motor @ 1120rpm). Vibration after retension are worse but with much different pattern. A high peak exactly at 4X belt frequency dominate the spectrum. No more widespread spectrum seen. The belt is smooth and quite. But cracked welding found on the motor support bracket.

vibration of machines that are mounted on floors or walls. Obviously, the best place to mount a vibrating machine is on the ground floor. Unfortunately (but fortunately for noise control consultants), this is not always possible. A typical problem is a rotating machine (such as a pump, AC compressor, blower, engine, etc) mounted on a roof, or on
To increase motor power, general-ly you have to increase the rotor volume or the speed of rotation since the B field strength is limited by the properties of magnet iron and the effective resistance of the rotor is limited by the need to cool the rotor. Figure 2 shows an evaluation of this torque expression for a 4-pole motor with τ R = 0.09 ...
