QJ型深井泵一、产品概述QJ型井用潜水电泵是电机与水泵直联一体潜入水中工作的提水机具，它适用于从深井提取地下水、也可用于河流、水库、水渠等提水工程：主要用于农田灌溉及高原山区的人畜用水，亦可供城市、工厂、铁路、矿山、工地供排水使用。二、产品特点1、电机、水泵一体，潜入水中运行，安全可靠。2、对井管、扬水管无特殊要求(即：钢管井、灰管井、土井等均可使用；在压力许可下、钢管、胶管、塑料管等均可作扬水管使用)。3、安装、使用、维护方便简单，占地面积小、不需建造泵房。4、为了防止井水中的沙粒进入电机内部，电机上端轴伸处装有两个油封，并安装一甩沙环，组成防沙结构。5、为了防止启动时水泵轴上窜，水泵轴和电机轴由联轴器连为一体，并在电机下部安装一上止推轴承。6、电机定子绕组采用优质潜水电机绕组线，绝缘性能高。7、水泵采用计算机CAD设计，结构简单，技术性能好。潜水电泵使用的条件是否合适，管理得当与使用寿命有直接的关系。三、性能范围：  流量：2-320m3/h；扬程：11-300m；转速：1450-2850r/min；井径：100-350mm；介质温度：≤20℃。  四、使用条件： 1、电源为50Hz，380V三相交流电。2、水泵第一级叶轮应潜入动水位1米以下，电机底部距井底部不小于3米，但潜入水中深度不大于70米。3、 水中固体物含量(按质量计)不大于0.01%，水中酸碱度PH值在6.5~8.5，氯离子含量不大于400mg/I。4、水温不高于20℃。5、井应正直(以能安装到位并能顺利提升为准，若偏斜较厉害，井径应略大或选用小一级井径的电泵)6、井必须有足够的涌水量(即大于额定流量)。________________________________________________________________________________________ 小贴士1：电动机必须完全潜入水中方可工作。小贴士2：电泵不准倒卧或倾斜使用。小贴士3：引线与电缆接头须按规定操作，详见说明书附图。小贴士4：电机运转2500小时应进行一次大修，1500小时应进行小检修。小贴士5：每排灌期(2500小时)进行一次检修保护，并更换损坏的易损件(叶轮、轴承与密封环等)。小贴士6：本公司现已开发出小型不锈钢潜水电泵(100QJ与4SP系列)，请有意向的客户来电垂询。 五、深井泵型号意义   六、QJ型井用潜水电泵性能参数及图片 型
