The forces, transferred from the motor to the working device, can be calculated most simply from the acceleration figures at the relevant drive frequencies and the vibration amplitude. You can just take the effective vibration amplitude for all types of motors in relation to the working weights from the motor characteristics on the following pages.
The vibration problems relating to the power trip test should be observed by tain components due to gearing, bear-induction motor are a combination of studying the changing amplitude of ings etc., transmitted via the struc-two groups which can be called me- the vibration on a spectrum analyer. ture. Also any spectrum component.

the rotating screen and is filtered when leaving the screen from the inside to the outside. Suspended solids are trapped on the inside surface of the screen, and raked upward as the screen rotates. The solids collected at the top of the inside of the screen are flushed out with flushing water down into a discharge trough for collection.
The standard inclined screen has an angle of inclination of 15 o. Lower angles of inclination increase the projected area of the screen aperture in the horiontal plane and the screen can handle a greater load. This is accounted for by capacity factor K6 K 6 1.0 0.01. 15 4-11 where. is the angle of inclination in degrees. The wet screen.

screen is supported on a steel coil spring suspension. One or more vibration mechanisms are mounted to a steel beam that spans the width of the screen. These vibration mechanisms, which use rotating eccentric shafts to generate vibration, are belt-driven using an electric motor. The screen.
a Effective vibration - measured single amplitude vibration, in inches multiplied by the service factor. Machine tools are excluded. Values are for bolted-down equipment when not bolted, multiply the service factor by 0.4 and use the product as the service factor. Caution Vibration is measured on the bearing housing except, as stated. b.

Vibrating Motors A vibrating motor is essentially a motor that is improperly balanced. In other words, there is an off-centered weight attached to the motors rotational shaft that causes the motor to wobble. The amount of wobble can be changed by the amount of weig.
The screen body is extremely sturdy and rugged made up of mild steel of adequate thickness. The thickness of the steel plates depends upon the sie of the screen and the selected motor. Depending on the material to be screened, the sieve analysis and other related factors, suitable screen decks are.
This is the most basic form of vibration monitoring. 3.2 Calculation of Frequency Spectra. The right column of the Basic Processes diagram shows that the time waveform can be converted to a frequency spectrum in order to show the analyst where the vibration energy is coming from. Frequency analysis is the essence of vibration analysis and.
More stringent specifications regarding motor vibration call for maximum velocity levels of 0.1 in.sec on the housing and 1.5 mils of displacement vibration on the shaft. The limits apply to a motor mounted on a seismic mass, and uncoupled or coupled to a piece of equipment in a way that eliminates any vibration in the driven equipment.
