a harmonic balancer sometimes crankshaft damper, torsional damper, or vibration damper is the same thing as a harmonic damper except that the balancer includes a counterweight to externally balance the rotating assembly. the harmonic balancer often serves as a pulley for the accessory drive belts turning the alternator, water pump and other .
a solid bowl centrifuge is a type of centrifuge that uses the principle of sedimentation. a centrifuge is used to separate a mixture that consists of two substances with different densities by using the centrifugal force resulting from continuous rotation. it is normally used to separate solid-liquid, liquid-liquid, and solid-solid mixtures. solid bowl centrifuges are widely used in various industrial applications, such as wastewater treatment, coal manufacturing, and polymer manufacturing. one
rotating unbalance is the uneven distribution of mass around an axis of rotation. a rotating mass, or rotor, is said to be out of balance when its center of mass inertia axis is out of alignment with the center of rotation geometric axis . unbalance causes a moment which gives the rotor a wobbling movement characteristic of vibration of rotating structures.
in physics, the degrees of freedom dof of a mechanical system is the number of independent parameters that define its configuration or state. it is important in the analysis of systems of bodies in mechanical engineering, structural engineering, aerospace engineering, robotics, and other fields.. the position of a single railcar engine moving along a track has one degree of freedom because .
the abec scale is an industry accepted standard for the tolerances of a ball bearing.it was developed by the annular bearing engineering committee abec of the american bearing manufacturers association abma . the abec scale is designed to provide bearing manufacturers dimensional specifications that meet the standards of precision bearings in a specified class.
vibrating conveyors are also suitable for harsh, very hot, dirty, or corrosive environments. they can be used to convey newly-cast metal parts which may reach upwards of 1,500 f 820 c . due to the fixed nature of the conveying pans vibrating conveyors can also perform tasks such as sorting, screening, classifying and orienting parts.
beer ball. another type of mini keg is the 'beer ball' or the 'party ball', a disposable plastic ball that usually holds around 5.2 us gallons 20 l , roughly the equivalent of 55 twelve-ounce beers, though they can also be found in a smaller 3.8-us-gallon 14 l size
vibratory bowl feeders are common devices used to feed individual component parts for assembly on industrial production lines. they are used when a randomly sorted bulk package of small components must be fed into another machine one-by-one, oriented in a particular direction. vibratory feeders rely on the mechanical behaviour of a part, such that when gently shaken down a conveyor chute that is shaped to fit the part, they will gradually be shaken so that they are all aligned. they thus leave t
a fire extinguisher is an active fire protection device used to extinguish or control small fires, often in emergency situations. it is not intended for use on an out-of-control fire, such as one which has reached the ceiling , endangers the user i.e., no escape route, smoke, explosion hazard, etc. , or otherwise requires the expertise of a fire brigade .
