概  述

      FY型耐腐蝕立式液下泵是一種單級單吸長軸式液下離心泵,其標記、額定性能點和法蘭連接尺寸等效采用ISO2858國際標準、技術條件采用IS05199標準。與原FY型耐腐蝕液下泵相比,具有體積小、效率高、節能效果好,運行可靠等優點。適用于輸送稍含固體顆粒、磨料的腐蝕性介質。

      泵的輸送溫度一般為0~ 105C。溫度在- 20~0C、105~ 180C時可采用保溫夾套及冷卻夾套，采用低溫或高溫耐磨導軸承,此類情況用戶應說明。

      如輸送介質有少量固體顆粒，滑動軸承應采用外潤滑方式(外接壓力大于0.2MPa的清水和其它允許的介質),此類情況用戶應說明。

      泵的工作壓力按1.6MPa設計。

      泵的性能范圍:流量為1.6- 2600m/h,揚程為5- 132m。

      根據所輸送介質的不同，FY型立式液下泵接觸液體部分的材質可選用鑄鐵(用符號H表示)、鑄鋼、1Cr18Ni9Ti(用符號B 表示)、1Cr18Ni12Mo2Ti(用符號M表示)、301、  304L、  316、316L、904、Lewmet合金、20號合金等材料制造。

General

      FY series corrosive vertical submerged pump is oneofsingle - stage single - suction long - shaft submerged cen-trifugal pumps . lts marks, performance points and dimen-sion of flange are designed according to InternationalStandard of ISO2858 . lts technical conditions are designedaccording to ISO5199.lt has litle volume, high effciency,power saving, operating liability compared with former FYseries corrosive vertical submerged pump.It can not pumpcorrosive medium which has solid particles and wearablematerials .

      The medium temperature varies from 0C to 105C.Heat preservation closed cover and low - temperaturewearable guide bearing are used when the temperature ofmedium is from 20C tooC, cooling closed cover andhigh temperature wearable guide bearing are used whenthe temperature of medium is from 105C to 180C .Thiscondition must be stated when ordering.

      If medium has littte solid particle ,  sliding bearingshould be outer - lubricated bearing, which shall be statedclearly when ordering(water and other allowed mediumwhose outer pressure is over 0. 2MPa).

Operating pressure is designedat 1.6 MPa.

 Performance range: Capacity:1.6 - 2600m3/h, head: 5- 132m.

 The materials contacting with liquid can be selected ascast iron(H),cast steel, 1Cr18Ni9Ti(B), 1Cr18Ni12Mo2Ti(M),304,304L, 306, 306L, 904, Lewmet Alloy, 20# Alloy according to different medium.
