、海水冷卻泵
、日常用泵,輸送介質(zhì)溫度應(yīng)低于75

12泵的性能參數(shù)應(yīng)符合表1的規(guī)定

1. SUMMARY

1.1 This pump applies to the fresh water, Seawater cooling pumps and daily

pumps driven by ship electric motors medium's temperature should be below

75

1.2 Pump performance parameters shah conform to the provisions of Table 1

2.泵結(jié)構(gòu)及裝配
、拆卸

21泵為立式

、單級、單吸式
、水平進(jìn)水及水平出水
。泵體底座為整體式結(jié)構(gòu)的船用立式離心泵。對于電機(jī)功率≤22KW的泵
,泵軸與電機(jī)軸直接聯(lián)接
,泵產(chǎn)生的軸向力和徑向力由電機(jī)本身的軸承支承。對于電機(jī)功率≥30KW的泵
,泵軸則通過帶中間聯(lián)軸器的彈性套柱銷聯(lián)軸器與電機(jī)聯(lián)接
。泵產(chǎn)生的軸向力及徑向力由安裝在軸承體上的一對球軸承支承
,軸承采用鋰基脂潤滑。軸封采用耐磨
、耐腐蝕材料制造的機(jī)械密封

2.Pump structure, Assembly、Demolition

2.1 Pumps are vertical, single-level, single-use type, level inlet and outlet type. The pump body base is the overall structure of the bunker-style vertical centrifugal pumps. For the pumps which powers are lower than 22KW, the pump shaft directly connect to the engine axis, Axial pump power generated by the pump is supported by the engine bearings itself. For the pumps which powers are lower than 30KW, the pump shaft connects to the engine through intermediate shaft coupling with flexible sets of pillars sales shaft. A pair of ball bearings installed in the radial body supports axial pump power generated by the pump. Bearings adopt lithium base resin lubricant. Bearing seals using wear-resisting, corrosion resistant materials mechanical sealed.

22直連式結(jié)構(gòu)泵的裝配

    電機(jī)聯(lián)軸器上電機(jī)軸伸位置正確后

,緊固緊定螺釘
,并把電機(jī)架緊固在電機(jī)
