3、dardApproval of an American National Standard requires verification by ANSI that therequirements for due process, consensus and other criteria for approval have been met bythe standards developer.Consensus is established when, in the judgement of the ANSI Board of Standards Review,substantial agreem

4、ent has been reached by directly and materially affected interests.Substantial agreement means much more than a simple majority, but not necessarilyunanimity. Consensus requires that all views and objections be considered, and that aconcerted effort be made toward their resolution.The use of America

26、art of Standard)ScopeThe purpose and aims of the Institute are to promote the continued growth of pump knowledge for the interest ofpump users and pump manufacturers and to further the interests of the public in such matters as are involved inmanufacturing, engineering, distribution, safety, transpo

27、rtation, and other problems of the industry, and to this end,among other things:a) To develop and publish standards for pumps;b) To collect and disseminate information of value to its members and to the public;c) To appear for its members before governmental departments and agencies and other bodies

28、 in regard to mattersaffecting the industry;d) To increase the amount and to improve the quality of pump service to the public;e) To support educational and research activities;f) To promote the business interests of its members but not to engage in business of the kind ordinarily carried onfor prof

30、iminatemisunderstandings between the manufacturer, purchaser, and/or user and to assist the purchaser in selecting andobtaining the proper product for a particular need.2) Use of Hydraulic Institute Standards is completely voluntary. Existence of Hydraulic Institute Standards does notin any respect

31、preclude a member from manufacturing or selling products not conforming to the Standards.Definition of a Standard of the Hydraulic InstituteQuoting from Article XV, Standards, of the By-Laws of the Institute, Section B:“An Institute Standard defines the product, material, process or procedure with r

32、eference to one or more of the following:nomenclature, composition, construction, dimensions, tolerances, safety, operating characteristics, performance,quality, rating, testing and service for which designed.“Comments from usersComments from users of this standard will be appreciated to help the Hy

33、draulic Institute prepare even more usefulfuture editions. Questions arising from the content of this standard may be sent to the Technical Director of the HydraulicInstitute. The inquiry will then be directed to the appropriate technical committee for provision of a suitable answer.If a dispute ari

34、ses regarding the content of an Institute Standard or an answer provided by the Institute to a questionsuch as indicated above, the point in question shall be sent in writing to the Technical Director of the Hydraulic Institute,who shall initiate the appeals process.RevisionsThe Standards of the Hyd

35、raulic Institute are subject to constant review, and revisions are undertaken whenever it isfound necessary because of new developments and progress in the art. If no revisions are made for five years, thestandards are reaffirmed using the ANSI canvass procedure.viii Hydraulic Institute Standards, C

42、nt pump consisting of a chamber containing gears, cams, screws, vanes,plungers, or similar elements actuated by relative rotation of the drive shaft to casing, and which has no separate inletand outlet valves. These pumps are characterized by their close running clearances.There are seven common bas

43、ic types of rotary pumps identified by the type of pumping element. Relationships betweenthese types of pumps are illustrated in Figure 3.1a.Figure 3.1a Types of rotary pumpsHI Rotary Pumps Types and Nomenclature 20152 Hydraulic Institute Standards, Copyright 1997-2015, All Rights ReservedCapability

44、 table overviewThe capability tables (see Tables 3.1a and b) and consolidated range charts (see Figures 3.1b and c) with individualtechnology descriptions provide an overview of operating ranges and application characteristics for the industrialrotary pumps covered in this document. These ranges are

45、 not absolute because custom designs at alternate speeds,clearances, or with special materials may be available through a thorough understanding of the application betweenthe user and the manufacturer. The maximum parameter listed is only an indication of the range for that parameterand typically no

46、t all maximum values can be obtained simultaneously. Relative capabilities (i.e., abrasive handling,shear sensitivity, and pulsation) are highly dependent on application conditions and the pump technology to which thecomparison is made. Shear sensitivity relates to the effect the pump has on the liq

47、uid. The abrasive handling capabilitiesratings allow material enhancements. Consultation with the supplier is recommended to confirm specific applicationrecommendations and to investigate special designs, which are often available to provide unique solutions.HI Rotary Pumps Types and Nomenclature 20
