The committee, which consists

43、of major manufacturers and users, has decided to view the submersible pumpas an integrated unit from the acceptance test point of view. This change and the adaptation of the same testacceptance grades as HIs new rotodynamic pump test standard and the new ISO 9906 pump test standard consti-tute the m

44、ajor changes. Minor updates, corrections, and refinements have also been made.This submersible pump test standard represents a major departure from the previous submersible pump test stan-dard (ANSI/HI 11.6 2001) in that the submersible pump is guaranteed and tested as a complete close-coupledunit.

45、If pump efficiency or pump power has been guaranteed, then the pump wire-to-water efficiency or electricinput power is guaranteed and tested, in addition to the mandatory flow and head test.This standard does not identify the various sources of losses within the boundary of the submersible pump unit

46、.When a manufacturer offers an efficiency guarantee for a submersible pump, or an input power guarantee, thatguarantee encompasses the entire pump unit. This standard specifies how acceptance testing shall be performedand it defines pump acceptance. The overall pump efficiency can be precisely deter

47、mined by dividing the outputhydraulic (useful or water horsepower) power delivered by the pump with the electrical input power delivered to theelectric motor. The user of this standard must understand that any attempt to calculate an individual componentsefficiency (such as pump, motor, cooling syst

48、em, seal, or bearing efficiency, to name a few) will only yield data ofapproximate magnitude and must not be used to judge a submersible pump units acceptance.It is not meaningful to compare pump test results from a submersible pump test based on this standard with testresults from tests performed t

49、o the old ANSI/HI 11.6 or any other pump test standards. See Appendix A for anexplanation of the difference between wire-to-water efficiency and pump hydraulic efficiency. Formulas used to esti-mate a submersible pumps hydraulic efficiency can also be found in this appendix.The pump acceptance test grades incorporated into this document are the result of a collaborative effort made byEuropump and the Hydraulic Institute.
