ABS Plastics
Acrylonitrile-butadiene-styrene plastics are ud extensively in the molding of vacuum cleaner cas and trim parts. It is an economical plastic which is lightweight but strong and resists stains and chemicals. See also our article on External Structure Materials & Durability small什么意思

Activated Charcoal
Charcoal from which most of the impurities have been removed. It is made by treating ordinary charcoal with steam and air heated to above 600 degrees Fahrenheit. It is the best adsorbent since its many empty spaces give it a large internal surface to hold particles.
Agitation wife是什么意思
汽车卡通短片The process of moving in a rapid and violent manner. Carpet is usually agitated by the brushes and sometimes a beater bar on the revolving brush roll in a vacuum cleaner. See also our article on the Effects of Brushing Action.
Air Flow
The movement of air from one location to another. In a vacuum cleaner, it generally refers to the movement of air through the vacuum cleaner or central vacuum system and is measured in cubic feet per minute (C.F.M.). It is one of the most important aspects of vacuum cleaner performance. Air flow in a vacuum cleaner is inverly proportional to the total resistance within the system and directly proportional to the suction created by the suction motor. For additional information, e our article on Air Flow through the System.
Air Pressure
The pressure of atmospheric or compresd air. At a level, atmospheric pressure is 1,013.2 millibars or 14.69 pounds per square inch. A vacuum cleaner's suction motor reduces the air pressure in order to create air flow. See also our article on Fan or Impeller Types & Performance.
Air Watts 德语培训
A specification developed in an effort to rate the output power of the vacuum cleaner inst
ead of its input power. It is bad on suction with air flow as measured at the vacuum cleaner inlet. See also our article on the Power of the Suction Motor.
ldtAllergen Filtration Bags
A special name Hoover gives to their high filtration bags. They are also known as MicroFiltration dustbags. According to Hoover, this dustbag "Traps 99% of particles down to 5 microns! Filters a wide range of airborne particles including many pollens, spores, other allergens and dust mites. Ideal for many with dust related or allergic discomforts. Electrostatically charged liner enhances the capture of extremely fine particles." For more information, e Bag Performance and Filtration Efficiency.
Amperage (Amps)
汽车维修资料网The strength of an electric current flowing through a wire or other electrical conductor expresd in amperes (amps). One ampere of current will flow through a conductor having one ohm of resistance when a potential of one volt is applied to it. Vacuum cleaners are often rated by the amount of amperage drawn from the electrical outlet whic
h flows through them. The maximum permitted for UL Approval is 12 Amps. See also our articles on the Power of the Suction Motor and Efficiency and Performance Ratings.
Armature
An armature is made of a laminated steel core which is wound with copper enamel-insulated wire. The windings are attached to a copper commutator near one end of the armature. It can be considered the heart of a motor since it is the armature's rotation, motivated by electrically created magnetic fields within the motor, that converts electrical energy into mechanical energy. See also our article on the Suction Motor Design & Operation.
Bakelite
Bakelite is an important thermotting resin made from phenol and formaldehyde which can be injection molded to make parts which are resistant to heat, chemicals and moisture. See also our article on External Structure Materials & Durability.
Ball Bearing
广州话翻译器A low friction type of bearing in which round steel balls rotate between a spinning inner race (small steel ring with a rounded grove on it's outer surface) and a stationary outer race (larger steel ring with a rounded grove on it's inner surface). The sides often have shield or al rings to retain the grea and keep the bearing as clean as possible.
人无完人英语Beater Bar
ownA long rigid bar or raid area on a revolving brush roll which pushes the carpet away from the roll, creating a rapid beating action. Stiff bristles on a brush roll can have a similar effect.
Beating Action
The rapid hitting action caud by a beater bar or stiff bristles on a brush roll. The effect of this is to help work the dirt and grit toward the top of the carpet.
Brush Roll
The brush roll is the part of a vacuum cleaner which contains rows of bristles and sometimes beater bars to agitate the carpet in order to significantly aid in the removal of
dirt from it. While often being in the shape of a cylinder, some are contoured, being more like an auger in appearance. It is mounted in the nozzle by its ends and contains bearings which allow it to be rotated at a high speed by the brush motor or turbine. Most vacuum cleaners u the same motor to create the suction and rotate the brush roll.
