INERTIA BASES FOR PUMPS
Inertia base frames and structural steel bases are designed and engineered for use in supporting mechanical equipment. Typically used with AAW vibration isolators for support and isolation of:
- Centrifugal Fans
- Air Handling Units
- Evaporative Condensers
- Cooling Towers
Inertia Base End Suction Pumps consist of structural steel channel perimeter frame, reinforced steel, equipment mounting templates with anchor bolts and seismic spring isolators with height saving brackets or recessed spring pockets upon request. Spring deflections in 1″ – 5″ are available. Inertia base thicknesses of 6″ – 12″ are available.
When Pump Concrete Inertia Base End Suction Pumps are filled with concrete, they become an inertia base and provide an effective means to isolate vibration and limit the motion of suction pumps.
Pump Concrete Inertia Base End Suction Pumps are rectangular in size and are engineered to support the base elbow of a suction pump. The seismic isolator housings are offset with the perimeter of the base. The isolator housings are identical in height within each series and come with easily accessible bolt holes for simplified installation. An elastomeric acoustical cup eliminates high frequency vibration, while color-coded springs permit ease of identification of load capacity. Spring housings have internal adjustments for use in most seismic and wind applications. Their rugged steel housing is designed to handle high wind and high seismic forces up to 2.0g. inertia base frames are specifically designed and engineered to receive poured concrete, for use in supporting mechanical equipment requiring a reinforced concrete inertia base for pump.
Inertia bases are used to support mechanical equipment, reduce equipment vibration, provide for attachment of vibration isolators, prevent differential movement between driving and driven members, reduce rocking by lowering equipment center of gravity, reduce motion of equipment during start-up and shut-down, act to reduce reaction movement due to operating loads on equipment, and act as a noise barrier.
inertia base frames, with poured concrete and supported by noise and vibration isolators, include use with open-type centrifugal chillers, reciprocating air and refrigeration compressors, chillers, and heat pumps, close-coupled and base-mounted pumps, centrifugal fans, internal combustion engines, and similar types of equipment.
Model CIB-L inertia base frames, when filled with concrete, meet all specifications for inertia bases, and when supported by proper vibration isolators, provide the ultimate in equipment isolation, support, anchorage, and vibration amplitude control.
CIB-L inertia base for pump frames incorporate a unique structural design which integrates perimeter channels, isolator support brackets, reinforcing rods, anchor bolts and concrete fill into a controlled load transfer system, utilizing steel in tension and concrete in compression, resulting in high strength and stiffness with minimum steel frame weight. Completed inertia bases using model CIB-L frames are stronger and stiffer than standard inertia base frames using heavier steel members.
Standard CIB-L inertia base frames are available in thicknesses of 6 in (152 mm), 8 in (203 mm), 10 in (254 mm) and 12 in (305 mm), in sizes tabulated, and include integral isolator support brackets, steel channel perimeter pouring frame, 1/2-in (13 mm) diameter reinforcing rods on 8-in (203 mm) centers each way, and steel anchor bolts prelocated and fixed in proper locations. CIB-L inertia base frames are delivered to the job site completely welded and ready to fill with concrete. On-job labor and installation time are minimized, resulting in maximum economy.
Acoustic Design and Noise Control in Architecture
Middle East Engineering Solutions can advise on all aspects of the acoustic design of commercial, public, industrial and residential buildings, covering control of noise from mechanical services and other installed equipment; insulation of the building shell against the ingress of external noise and the egress of internal noise; sound insulation within the building and optimizing acoustic conditions within specific rooms or spaces.
In the case of a large building development, for example, Middle East Engineering Solutions would carry out an environmental noise survey to establish the prevailing noise climate and anticipate relevant changes from traffic or other forecasts; set suitable noise criteria for the various spaces; specify attenuation requirements for the ventilation system; determine the sound insulation and vibration isolation needed for machinery spaces; specify sound insulation requirements for the building envelope; advise on room layout and partitioning to achieve the required levels of privacy, and deal with all details of the acoustic design of rooms.
Middle East Engineering Solutions is therefore able to undertake responsibility for all aspects of the acoustic design of buildings. If required, these services will include supervision of the installation of noise and vibration control equipment and testing on commissioning of the building. In the case of dwellings such testing would include the measurement and appraisal of sound insulation for the purposes of Building Regulations approval.
Middle East Engineering Solutions can undertake the acoustic design of auditoria for music and speech such as concert halls, recital rooms, theatres, multipurpose spaces, lecture theatres and studios to optimise the conditions in accordance with the intended usage. The aspects covered may include the essential isolation of the auditorium from external noise and vibration, control of noise from mechanical services and design of the auditorium size, shape and finishes to achieve the required reverberation time and sound propagation characteristics.
Middle East Engineering Solutions services in the field of auditorium acoustics extend to the design of electro-acoustic systems for special applications, in particular low-frequency reverberation enhancement systems.
Middle East Engineering Solutions offers a design, specification and commissioning service for specialised electro-acoustic systems. Such systems are custom designed, thereby permitting a high degree of flexibility with regard to both ergonomic and aesthetic requirements, whilst achieving a careful balance between technical excellence and economy. Middle East Engineering Solutions is fully equipped in designing and supervising the installation of high quality speech reinforcement systems for Churches and Cathedrals. Of particular interest is the range of loudspeakers, designed to direct high quality sound down to the congregation without the need to angle the loudspeaker away from the supporting wall or column. Combining technical ingenuity with functional design ensures an unobtrusive appearance, which can be of great importance in avoiding the disruption of fine architectural lines within Churches and Cathedrals.
Noise from and within Industry
Middle East Engineering Solutions is frequently asked to advice on the control of noise both from and within factories and other industrial premises in order to ensure the minimum risk of damage to employees’ hearing or annoyance to the local community.This might typically involve measurement surveys,remedial design and the management of the ensuing noise control program in existing factories or expert assistance with the design of new factories in order to satisfy the relevant Statutory Instruments and Codes of Practice associated with The Health and Safety at Work Act, the Noise at Work Regulations and the Control of Pollution Act.
Middle East Engineering Solutions can carry out detailed noise surveys to identify the level of risk involved and to provide guidance and advice detailing the measures that should be taken by an employer to effectively protect the exposed workforce.
PERFORMING ARTS VENUES
Middle East Engineering Solutions focus on natural sound and vibration comes to fruition in the design of performing arts venues. All aspects of the acoustics,including technologically demanding work like scale modeling and building isolation, are handled in-house.Our team brings a higher level of scientific capacity to acoustic design, tempered by years of experience and an intuitive insight as performers and musicians.
The acoustical design of cinematic theatres entails the sound isolation of the theatres from exterior noise, and from adjacent theatres,acoustic design of the room, and evaluation of the HVAC design with respect to noise generation. Our services in this area include:
Computer modeling of rooms to determine all acoustic parameters including reverberation time,early decay times (EDT),and sound pressure level. This analysis can also be used to evaluate some acoustic anomalies within the room.
We provide detailed mechanical system design criteria early on in a project, so that the mechanical engineer can include these considerations early in the design. We then evaluate the system after it is designed to calculate noise levels within the theatre.
With modern digital sound systems, the evaluation of wall design between theatres is critical.The design of the wall itself is only one part of the entire process. Structure borne sound transmission through floors and sidewalls must also be evaluated. Exterior and interior wall designs are evaluated and CAD designs provided to the architect.
