| 1．概述Summary 1.1 CLLa系列船用立式离心泵是我公司参照制造并经中国船级社认可的产品。本产品是用来输送海水、淡水、生活污水，作为冷却、消防、舱底压载和其他一般排水用，也可用于工业和城市供水。输送介质温度应低于80℃。 The CLLa Series Marine Vertical Centrifugal Pump is make according to foreign technology and approval by CCS．The pump．can be used to transport sea water,fresh water,sanitary sewage for cooling,furc，pump and deliver bottom ballast water or common drain off water,also can be used for industry,or cities supplies water．The temperatures of the media transferred should not exceed 80℃． 1.2当输送介质含有较大泥砂量时，旋液分离器将泵高压端液体引入旋液分离器进行分离。经分离净化后的液体引入密封腔内进行冲洗，将带有较多泥砂的液体引至泵的低压区，以此延长机械密封寿命，顾客如需安装，应在合同中注明。 When the media transferred contain relatively more silt,the liquid in high-pressure district will be introduced and separated in the rotation liquid segarator. After separate and purify,the liquid will be entry the sealed cavity to wash up,then the liquid contains silt will be guide to the low-pressure district．By doing these,the service life of the machinery sealing in the sealed cavity will be extend．Our customers who want pumps installcd are suggested to spccify it clearly in the contract． 1.3当本泵作为消防泵使用时，本泵应设自吸装置，并在泵的排出管路设置安全阀，以保证消防系统安全、可靠地使用。作舱底压载泵用，也应配置自吸装置。 Regard as this pump as fire control time spent,the pump should be set up self-suction device,ａnd set up the relief valve on the discharge pipeline of the pump，guarantee the system of fire control use security reliably．Regard as this pump as bottom ballast time spent,should set up self-suction device too． 1.4 CLLa系列泵的进出口法兰符合GB572“船用铸铜法兰"。 The imports and exports flange of the CLLa series pump accords with GB572“Marine cast brass flange"． 1.5型号意义Type meaning： |
