One, overview centrifugal pump has function range big, discharge simple, movement mixes even, structure reliably maintenance is convenient wait for an advantage, the application in industrial production is most accordingly wide. Reciprocating pump is used when dividing high-pressured little flow, metric when maneuver measures pump, vortical pump or cubage type pump are used when medium contains gas, stickiness medium uses rotor pump outside, the others circumstance all chooses centrifugal pump commonly. According to statistic, in device of oil, chemical industry, the makes dosage occupies pump gross 70 ％～ of centrifugal pump 80 ％ . Centrifugal pump can be divided by its structure wait for suspensory of the cantilever type, two end type that prop up, vertical. Note: Centrifugal pump has by its seal without the axis will divide, can divide to have sealed pump is mixed without sealed pump (also say not to have leak pump) , without sealed centrifugal pump cent is pump of magnetic force drive and screen pump. The article is only right the level that has sealed pump is made analyse. Note: This watch is picked from API610 the 7th edition 2, commonly used standard explains 1.

API610API, it is American oil consortium (the abbreviation of AmericanPetroleumInstitute) . The purpose of publication API610 standard is to offer to purchase a standard, in order to facilitate of centrifugal pump make and purchase. API610(the 7th edition) be to be aimed at oil refine factory to put forward with centrifugal pump, its standard name is " general refine factory uses centrifugal pump " (CentrifugalPumpsforGeneralRefineryServices) . But actually, of use API610 standard is refinery not only, the domain such as oil, chemical industry, natural gas often also all uses API610 level. For applicable this one need, the API610(that promulgated 1995 the 8th edition) incognito for " oil, heavy chemistry and natural gas are industrial centrifugal pump " (CentrifugalPumpsforPetroleum, heavyChemical, andGasIndustryServices) , go up in content relatively on one edition has bigger fluctuant. API610 gets attention fully to energy-saving problem. API610 requirement manufactory and the use factory production in equipment, choose and run the seeks innovation actively energy-saving means in waiting for place to use segment. The total cost that if this is planted,reduces operating period and do not send sacrificial safety or dependability, should encourage use. Additionally the criterion for evaluation when choice device should be in with equipment service life period the total cost inside is accurate, is not with equipment purchase charge to be accurate. In oil and chemical domain, the occasion that uses API610 level is more. International Organization for Standardization also adopted API610 standard, fu Zhi at standard number ISO/CD13709. At present the API610 of latest edition is the 9th edition that issued 2003, the requirement of the 9th edition and photograph of the 8th edition are compared, make the requirement of many sided be reduced somewhat. Because pump factory uses the standard drag in of new version to need to be made afresh to a lot of moulds, because this arrives till now, the pump that pump factory produces still basically is the 6th, 7 or the pump of the 8th edition. 2.

ISO5199ISO is the abbreviation of international Organization for Standardization. ISO5199, technicalSpecificationforCentrifugalPumps, class Ⅱ () of class of Ⅱ of standard of centrifugal pump technology, main basis is DIN standard of Germany. Its over all dimension, function accords with ISO2858 standard; Base accords with ISO3661; The cavity measure that mechanical and sealed or soft filling uses accords with ISO3069; Class of function experiment B accords with ISO3555, c class accords with ISO2548. ISO5199(includes to be equal or consult the national level of this standard) apply to centrifugal pump of horizontal cantilever type, express 1 medium OH1 and OH2 namely. Accord with ISO5199(to include to be equal or consult the national level of this standard) centrifugal pump calls ISO pump. Chinese GB5656/T, german DINISO5199, NFISO5199 equivalent of France uses ISO5199; ISO5199 of BS6836 adopting equation. Chinese GB5662, german DIN24256, british BS5257, french NFE44121, equivalent or adopting equation ISO2858. 3.

1M, 1991SpecificationforHorizontalEndSuctionCentrifugalPumpsforChemicalProcess(horizontal axial is inspiratory chemical centrifugal pump) with ASMEB73.

2M, centrifugal pump of chemical industry of 1991SpecificationforVerticalIn-lineCentrifugalPumpsforChemicalProcess(vertical pipeline) it is American state level, weave jointly by pump factory and chemical manufacturer, ASMEB73.

1M standard applies to the centrifugal pump of horizontal cantilever type that leg installs only, express 1 medium OH1 namely. ASMEB73.

2M standard applies to vertical conduit centrifugal pump, express 1 medium OH3, OH4, OH5 namely. The standard of pump of ASME chemical industry of the others has: ASMEB73.

GB3215 GB GB3215, 1989 " refine factory, chemical industry and petro-chemical flow use centrifugal pump current technology condition " consult basically API610 the 6th edition weaves and become. 5.

GB/T5656 GB GB/T5656, 1994 " only course, sheet sucks condition of technology of chemical centrifugal pump " consult to ISO5199 weaves and be become. Its relative standard is like GB5662 " axial is inspiratory centrifugal pump (16Bar) is tagged, function and dimension " consult ISO2858, GB5661 " axial is inspiratory centrifugal pump machinery is sealed the cavity measure that uses with soft filling " consult ISO3069, GB5660 " axial is inspiratory centrifugal pump base and installation dimension " consult ISO3661. Hydraulic function experiment presses GB3216 " pump of centrifugal pump, mixed flow, axial-flow pump and method of vortical pump experiment " C class or B class undertake (consult ISO2548, ISO3555) . 6.
