Loose component

Vibration appears/disappears suddenly with mcreasmg/decreasmg speed, respectively. Loose component Rotor sleeves/impellers become loose as speed is increased Bearing liners, housings, or selfaligning spherical casts have loose fits Loose casing or supports... 

Vibration peaks at specific speeds/high axial vibration is often present. Siib-harmomc Usually occurs as a result of loose components or as a result of aerodynamic or hydrodynamic excitations areas to be investigated for coiTection are seals, thrust clearance, couplings, and rotor/stator clearance... 

Equipment failure can severely hamper data collection. Many equipment failures are caused by simple malfunctions e.g., blown fuses, dead batteries, loose components or broken wires. The... 

The European safety standards stress an important principle called the singlefault concept that is at the core of safety philosophy. This principle states that even under a single fault (a wire coming loose, component failure, short/open circuit, insulation failure, etc.) at least one level of protection (basic insulation) must be... 

Section exhibits chatter. Knife angle wrong—check angle is set to 5/6 . Loose component—check security of knife holder, knife, and block. 

If boiling is to be detectable it has to be audible above the background noise. There are two main sources of background noise which can interfere with ABND rattling of loose components, and cavitation. 

Loose components of ammunition, packing materials, conveyors, skids, dunnage, empty boxes, and other similar material shall not be stored in magazines containing ammunition or explosives. 

Periodic checks or tests of laboratory fume hood performance are important in protecting workers health. With normal use the hood s efflciency in containing or capturing contaminants may decrease for many reasons normal wear, loose component parts (e.g., fan belts), out-of-adjustment dampers, clogged air cleaners, and ductwork blocked by dust and debris. 

There was also an increased incidence of cement particulate in the fibrous capsule. Examination of the interface of the non-loose component in late loosening revealed the same trabecular hypertrophy and reorientation, but minimal cement particulate and a thin fibrous capsule. The microscopic findings in early and late loosening are summarized in Table 3. 

Chromatography is a method for separating mixtures of substances into their individual components. Substances can be loosely categorized as volatile (including gaseous) and nonvolatile. The terms are... 

The basic manufacturing process involves thorough blending of the components, especially the pigments, and comminution with the aid of a variety of mills to reduce the particle size. Loose powders ate filled without additional processing. 

Prevailing interest rates probably tend to reflect an estimate of future inflation and contain a component that can be attributed loosely to inflationary expectations. However, the classical treatment is to assume that an inflation-free interest rate, r and average inflation rate, r, over the project lifetime can be identified. A discount factor (1 + r) can be modified (25) so that...

Ratio of the volume of loose molding compound to the volume of the same amount in molded solid form ratio of density of solid plastic component to apparent density of loose molding compound. 

Equipment grounding is the grounding of non-current carrying con ductive parts of electrical equipment or enclosures containing electi ical components. This provides a means of carrying currents caused by insu lation failure or loose connections safely to ground to minimize the danger of shock to personnel. 

The second method uses the slip frequency to monitor for loose rotor bars. The passing frequency created by this failure mode energizes modulations associated with slip. This method is preferred since these frequency components are within the normal bandwidth used for vibration analysis. 

Mechanical looseness Looseness, which can be present in both the vertical and horizontal planes, can create a variety of patterns in a vibration signature. In some cases, the fundamental (lx) frequency is excited. In others, a frequency component at one-half multiples of the shaft s running speed (0.5x, 1.5x, 2.5 x, etc.) is present. In almost all cases, there are multiple harmonics, both full and half. 

Vertical Mechanical looseness in the vertical plane generates a series of harmonic and half-harmonic frequency components. Figure 44.37 is a simple example of a vertical mechanical looseness signature. 

The term solvent is loosely applied to the volatile component of a paint, though this component may in fact consist of a true solvent for the medium plus a non-solvent or diluent. When such a mixture is used, usually with the aim of reducing cost or obtaining a higher solids content at a given viscosity, care must be taken to ensure that the diluent is more volatile than the true solvent in order that the medium shall remain in solution during the drying process. 

In the older battery literature the term separator is frequently used very loosely, to include all nonmetallic solid components between the electrodes, such as supporting structures for active materials (tubes, gauntlets, glass mats), spacers, and separators in a narrow sense. In this section, only the last of these, the indispensable separating components in secondary cells, will be termed separators , distinguished from the others by their microscopically small pores, i.e., with a mean diameter significantly below 0.1 mm. 

A snap can be characterized by the geometry of its spring component. The most common snaps are the cantilever type, the hollow-cylinder type (as in the lids of pill bottles) and the distortion type (Fig. 4-15). These snaps include those in any shape that is deformed or deflected to pass over interference. The shapes of the mating parts in a hollow cylinder snap is the same, but the shapes of the mating parts in a distortion snap are different, by definition. These classifications are rather nominal, because the cantilever category is used loosely to include any leaf-spring components, and the cylinder type is used also to include noncircular section tubes. 

At R > 400 pm the orientation of the reactants looses its importance and the energy level of the educts is calculated (ethene + nonclassical ethyl cation). For smaller values of R and a the potential energy increases rapidly. At R = 278 pm and a = 68° one finds a saddle point of the potential energy surface lying on the central barrier, which can be connected with the activated complex of the reaction (21). This connection can be derived from a vibration analysis which has already been discussed in part 2.3.3. With the assistance of the above, the movement of atoms during so-called imaginary vibrations can be calculated. It has been attempted in Fig. 14 to clarify the movement of the atoms during this vibration (the size of the components of the movement vector...
