DIGITAL VIBRATION METER DIGI-VIBRO MODEL 1332B   [General Introduction] As long as rotating or reciprocating machinery is running successfully, it keeps you, as well as itself, safe and secure. But once the machinery gets into trouble, it could produce a high level of vibration to threaten your safety. The DIGI-VIBRO provides vibration measurement for innumerable kinds of machinery, including, but not limited to, pumps, blowers, machine tools, automobiles, and aircraft. Here is a small fraction of the numerous applications of the DIGI-VIBRO: ///////////////////////////////////////////////////////////////////////////////////// PDF 파일보기 : [Features] * Vibration measurement for blowers used to dry automobiles after * they are painted * Vibration measurement at the location of mainframes * Solenoid valve actuation condition checking * Machine tool failure inspection * Maintenance of general-purpose engines * Maintenance of chassis dynamometers used for automotive testing * Bearing fault checking on blowers installed at garbage * incineration plants * Bearing wear checking on automatic grinding machines * used to fabricate clock parts * Amplitude and acceleration measurement for vibration testers * Measurement of resonance points on instruments to which engine vibration is imparted * Automatic medicine packing machine actuation condition checking * Routine checking on pumps and blowers installed at petrochemical plants *Transformer howling checking * Numeric representation of the actuation conditions of cell phone vibrators * Spindle vibration measurement * Cooling tower fan maintenance [Select Measurement Modes] 1) Acceleration measurement mode Acceleration measurement mode is suited for measuring high-frequency vibrations, such as those from a deteriorated bearing. Bearings make several tens to several hundreds of turns each time the rotating machine in which they are used completes one turn. They also generate shock pulses when flawed or chipped. Acceleration measurement is the ideal way of detecting these pulses. 2) Velocity measurement mode Velocity is defined as a rate of displacement per unit time, indicating a speed of said vibration. The value of velocity, which is expressed in the unit of mm/s (RMS), is proportional to both displacement and frequency. Velocity is a mode suitable for investigating general machine conditions, as also specified in ISO 10816-1 as a typical indicator of mechanical vibrations. Applicable frequency range is 10 to 1,000 Hz. 3) Displacement measurement mode The DIGI-VIBRO reads the actual travel of a vibrating object as a double amplitude, for example, as 30 mP-P (micrometer peak-to-peak). This measurement mode is the easiest to understand and mostly widely used among the three. Ideal for measuring the vibration of rotational components, such as an imbalance. The frequency range is narrow, from 10 Hz to about several hundreds of Hz. [Concept of Acceptance/Rejection Criteria] When it comes to vibration measurement, one question always confronts me; how should I make acceptance/rejection decisions? The vibration value criteria for evaluation of machine conditions are classified into "Tendency management," "Similarity comparison," and "Absolute value evaluation." Tendency management: This is the most steady and practical evaluation method. This method periodically measures vibration values, compares them by old reference vibration values that were obtained when the machine was running in the best conditions, obtains the differences (increases in vibration values), and judges a maintenance time from them. Generally, it is said that the vibration values keep on going up after passing over the vibration value of about 1.6 times of a normal vibration value. When the vibration of a test machine reaches 2 to 3 time of the normal vibration value, the machine must be overhauled.   The graph shown below is a record of periodic vibration measurements of a certain blower. Since faults were detected on the side opposed to the motor, but not in the motor itself, the machine has been overhauled to return to normalcy. Similarity comparison: This method compares vibration values of machines of the same type and judges a machine of the higher vibration value (indicating the machine is abnormal). Absolute value evaluation: This method judges the vibration value according to reference vibration values defined by machine scales by ISO 10816-1. [Machien Group] Class 1 Individual parts of engines or machines (typically electric motors of up to 15 kW) built in as parts of complete machines. Class 2 Middle scale machines having no particular base (typically electric motors of 15 kW to 75 kW) and engines or machines (300 kW maximum) mounted on a rigid base. Class 3 Large scale generating machinery or rotating machines mounted on a rigid base. Class 4 Large scale generating machinery or rotating machines mounted on a comparatively soft rigid base (for example, turbo generator sets and gas turbines of output of 10 MW minimum). [Evaluation zones] Zone A Vibration zone including vibration values of a new installed machine (Good) Zone B Vibration zone in which a machine can run long without any limitation (Acceptable) Zone C Vibration zone in which a machine cannot be expected to run long (Unsatisfactory) Zone D Vibration zone in which a machine may be damaged (Unacceptable) 1) Standard Type Model 1332B Has a standard measuring range.
