摘要： An apparatus and method for machine data collection includes a hand-held personal computer (HPC) having route-based machine information data stored therein, and at least one hand-held sensor unit which includes a sensor for sensing an operating characteristic of the machine. The sensor unit includes a microcomputer for controlling the overall operation of the sensor unit, and a wireless communications port for wirelessly communicating with the HPC and/or other peripheral device. Wireless communications between the HPC and the sensor unit include uploading route-based machine information and instructions from the HPC to the sensor unit, and downloading collected sensor data from the sensor unit to the HPC. Data may also be manually input to the HPC, including reading from control panels and process gauges. All LCD visually displays information and instructions to the operator, and a set of headphones aurally informs and instructs the operator with regard to data collection. Data may be transmitted wirelessly from the sensor unit to the HPC as the data is being generated, or data may be stored in the sensor unit over multiple data measurement points and then downloaded to the HPC or other peripheral device. In a distributed database, the sensor unit is configured to read a bar code or memory module positioned adjacent a measurement point of the machine, and each memory module is used to store data corresponding to test point location, sensor unit analysis setup, alarm levels, route-based information, and the like.

摘要： The disclosed invention senses a machine's vibration spectrum, converts the vibration signal into a frequency-domain vibration spectrum, and analyzes the vibration spectrum to generate a narrowband alarm limit envelope against which the vibration spectrum of a previously uncharacterized machine may be compared. The limit envelope is generated from the test vibration spectrum of the machine which is the subject of the test, thus providing a performance benchmark against which to compare the vibration level of the previously uncharacterized machine. A limit envelope is also generated from a test vibration spectrum which has been designated as a reference or baseline spectrum. Further, a limit envelope is generated based upon a mean spectrum which is generated by combining several test vibration spectra. A limit envelope is also generated based upon mean and standard deviation spectra when a statistically significant number of test spectra are available.

摘要： An alignment analyzer for facilitating the alignment of a machine set including co-rotatable in-line shafts includes a display device on which separate offset misalignment and angle misalignment components are displayed as a single point in an x-y coordinate system. The coordinates of the point are the individual misalignment components. Also displayed on the display device are curves representing "acceptable" and "excellent" tolerance ranges. The displayed point and the curves together indicate whether the combined offset and angular misalignment is within or without the "acceptable" tolerance range, and whether the combined offset and misalignment is within or without the "excellent" tolerance range. Also disclosed is a method whereby the amounts of offset and angular misalignment in a given plane are computationally combined to determine a combined misalignment amount for that plane, and then compared either to a value representing a tolerance limit for "acceptable" alignment, to a value representing a tolerance limit for "excellent" alignment, or to both values.

摘要： A hand-held apparatus gathers and analyzes test data associated with rotating electric machines, where the test data is indicative of one or more operational characteristics of the mechanical equipment. The apparatus, which is operable to be carried by an operator from one machine to another along a test route, includes a sensor input port for receiving a sensor signal from a sensor, where the sensor signal is indicative of one or more operational characteristics of the rotating electric machines. The apparatus also includes a signal conditioning circuit for receiving the sensor signal, and for conditioning the sensor signal to produce a conditioned signal which is appropriate in format to be digitally processed. A processor, which is coupled to the signal conditioner, receives and processes the conditioned signal according to processing instructions and processing parameters to produce a test spectrum. The processing parameters determine one or more characteristics of the test spectrum. A memory device, which is coupled to the processor, stores a plurality of executable test expert modules, each containing the processing instructions for processing the conditioned signal in a particular way to determine one or more of the operational characteristics of the rotating electric machines. An operator input device is coupled to the processor for receiving input from the operator to select one of the test expert modules to be executed to process the conditioned signal according to the processing instructions contained in the selected module. The apparatus further includes a display device for displaying the test spectrum to the operator. The test expert modules contain processing instructions for determining whether the processing parameters have been set according to a predetermined configuration for a particular test point on the test route, and for processing the conditioned signal in a way dependent upon whether or not the processing parameters have been set according to such a predetermined configuration.

摘要： A device detects an emission source of a vibration signal against a background of noise, where the vibration signal is produced by a mechanical system and has one or more frequency components. A sensor senses the vibration signal and produces a sensor signal corresponding to the vibration signal. The sensor has a mechanical frequency selection structure for mechanically resonating at desired frequencies and for mechanically attenuating a frequency component of the vibration signal having a frequency outside the desired frequencies. The mechanical frequency selection structure thus produces a mechanically-tuned sensor signal. Electrical frequency selection filters electrically attenuate a frequency component of the mechanically-tuned sensor signal having a frequency outside the desired frequencies. The electrical frequency selection filters thus produce an electrically-tuned sensor signal. The device has at least one amplifier with gain for producing an amplified signal corresponding to the electrically-tuned sensor signal. An amplitude characteristic determination circuit determines an amplitude characteristic corresponding to the vibration signal's amplitude. The amplitude characteristic determination circuit also generates an amplitude indication based on the amplitude characteristic. The amplitude indication and adjusts the gain of the amplifier based at least in part on the amplitude indication.

摘要： The operational condition of a machine is evaluated when the machine's vibration spectrum deviates from an acceptable state, where an acceptable state is defined by an alarm limit envelope. The amplitude of individual peaks within the machine's vibration spectrum is compared to the alarm limit envelope, and a deviation severity value characterizing the severity of the machine's deviation from an acceptable state is determined for each deviating peak. The deviation severity value represents the severity of deviation when at least one individual peak within the machine's vibration spectrum exceeds the alarm limit envelope. The deviation severity value is obtained by determining the peak excess magnitude for each vibration peak, where the peak excess magnitude is the amount by which the amplitude of each deviating vibration peak exceeds the alarm limit envelope level. The peak excess magnitude is then normalized by a frequency-dependent normalization factor. The ratio of the peak excess magnitude to the alarm limit envelope level for each vibration peak is determined. The deviation severity value for the spectral feature under analysis is then determined by selecting the larger of the severity value based on the excess magnitude and the severity value based on the excess ratio. The deviation severity of individual peaks as well as complex features within machine vibration spectra, such as individual peaks and families of harmonic and sideband peaks, may be determined as well to provide information concerning individual fault conditions.

摘要： A system for managing the alignment of a plurality of machine sets includes a portable alignment analyzer for calculating machine moves tending to bring the shafts of a machine set into alignment, and a base computer. A database of alignment documentation for the machine set is maintained in the base computer, the database including alignment fixture setup data, machine dimensions and tolerances, by way of example. A data link at least periodically enables communication between the base computer and the portable alignment analyzer. When the data link is active, alignment documentation for the machine set may be selectively Loaded into the portable alignment analyzer, and measured misalignment data may be selectively Dumped to the base computer for storage in the database. The system allows previously entered and stored machine-specific setup information to be used for a current alignment job, requiring only minor changes in the field.

摘要： The specification discloses apparatus for aligning rotatable in-line machine shafts. In a preferred embodiment, the invention provides an alignment system having a sensed point positioned for rotation with the shaft to be aligned to provide a reference point against which misalignment is measured. The position of the sensed point is adjustable in three-dimensional space by an adjustment system so that the sensed point may be easily secured in a desired location to eliminate errors attributable to movement of the sensed point or improper location of the sensed point. In addition, the alignment system provides a capacitive displacement system to more accurately sense the sensed point, binary blocks to facilitate proper vertical positioning of the sensed point, and an improved chain assembly to facilitate mounting of the alignment system and to reduce errors of the type common to conventional alignment systems.
