ANSI HI 5.2-2000 pdf download Vertical Pumps for Installation, Operation and Maintenance
Vertical pumps, when properly installed and operated, and when given reasonable care and maintenance, will operate satisfactorily for a long period of time. The following paragraphs outine the general principles that must be considered to ensure trouble-free pump operation. Vertical pumps are built in a wide variety of designs and for many different services. The manufacturer’s instruction book should be studied carefully and followed, as there may be specific requirements for a particular machine or application which cannot be cov- ered in a general discussion.
2.4.1 Scope This Standard applies to vertical centrifugal pumps that are driven by vertical electric motors or horizontal engines with right angle gears. It indudes installation, operation and maintenance.
2.4.2 Pre-installation instructions
2.4.2.1 Unloading/inspecting equipment received Immediately upon receipt of the pump equipment, check carfully to see that all items have been received and are in undamaged condition. Report any shortage or damage to the transport company han- dling the shipment and the equipment manufacturer, noting the extent of damage or shortage on the freight bill and bill of lading. This should be done at once. Par- ticular care and close adherence to the manufacturer’s recommendations are required when unloading long, slender components such as shafting. Improper placements of slings or chains can result in deformation or other serious damage. Do not leave the unit exposed to weather or construction hazards, which may cause damage to the equipment.
2.4.2.2 Storing equipment at site
2.4.2.2.1 Short-term The pump and equipment, as shipped, have adequate protection for short-term (60 days) storage in a coVered, dry and ventilated location at the job site prior to installation.
2.4.2.2.2 Long-term If the equipment will be subject to extended (over 60 days) storage conditions prior to installation, then the manufacturer must be advised about storage duration, so that special protection can be provided for the equipment. Periodic rotation of the pump and driver shaft is recommended during long-term storage.
2.4.2.3 Handling equipment and tools for installation For typical installations, the fllowing equipment must be available at the job site when instlling or removing the pump: Suitable overhead lifting equipment of adequate capacity to lift the driver, the entire pump (without driver) or the heaviest subassembly of the pump. Adequate headroom must be provided to accommo- date the longest section of the pump to be handled, including rigging. Properly sized slings, chains and shackles for attaching to the equipment lifting lugs.
Eye botts are required for handling pump sections when lifting lugs are not provided. I-beams for supporting pump subassemblies at the foundation when it is necessary to install the pump in sections. Common millwright’s tools are used for this type of work, including a machinist level to ensure proper leveling of the foundation plate.
