Description

自控流体喷射引流提升泵 技术领域
本专利涉及一种泵， 特别是涉及一种采用流体喷射真空技术引流的提升泵。 背景技术
泵是输送液体介质的主要设备之一， 广泛应用于石油、 化工、 电力、 城建、 环保、 污水处理、 食品制药、 合成纤维、 采矿、 造纸、 建筑、 冶金、 消防、 自 来水等工业部门。 目前泵在吸排低位介质的使用工况中广泛采用的工艺措施有:
1、 普通离心泵配用水环式真空泵： 其工作原理为利用水环式真空泵给泵 系统制造真空条件， 使介质在大气压力下进入泵系统后起动泵来排水， 此种方 法存在的弊病是排气时间长， 设备使用寿命低， 故障率高， 不适应酸、 碱、 盐 类化工产品的特殊工况等。
2、 自吸泵： 其工作原理为利用泵腔内预存的介质在泵的作用下， 在内循 环的过程中将吸入管道中的空气裹夹排出后， 才能正常运行， 其缺点为排气时 间长、 性能范围窄、 效率低。
3、 建筑低位泵房或高位蓄水池： 其工作原理是利用位差给泵制造入口压 头， 其弊病是基建投资大， 占地面积大， 设备维护保养困难， 以上几种工艺措 施均存在着设备在冬季必须保温加热的问题。
4、 泵吸入口端安装底阀： 泵运转前灌注引水后， 起动运行， 其弊端是底 阀易腐蚀泄漏， 必须经常更换。
5、 采用立式混流泵、 轴流泵、 旋流泵， 将泵插入液下使用， 由于泵均属 大型泵， 重且长， 检修安装需大型吊装设备， 检修困难， 维护运行费用大。
发明内容
本发明的目的是提供一种排气时间短， 出水快， 节省能源， 适用范围广的 自控流体喷射引流提升泵。
采用的技术方案是：
自控流体喷射引流提升泵， 包括流体喷射引流装置、 输送泵， 所述的输送 泵上装设有液位传感器， 其特征在所述的输送泵上部开设有排气孔， 排气孔通 过吸气管与所述的流体喷射引流装置气密性连接。
上述流体喷射弓 I流装置为内动力型流体喷射弓 I流装置， 该装置包括壳体、 设置于壳体内的流体增压机和流体真空喷射器， 所述的流体增压机通过连接管 与流体真空喷射器相联通， 流体真空喷射器的动力流体来自于流体增压机， 所 述的流体真空喷射器上引出有真空吸管， 真空吸管上装设有真空电磁阀， 真空 吸管的引出端与所述的输送泵上的排气孔气密性连接。
上述流体喷射引流装置， 也可为外动力型流体喷射引流装置， 该装置包括 壳体， 装设于壳体内的流体真空喷射器， 流体真空喷射器与一外供压力流体输 入管相连接， 外供压力流体输入管上装设有外供压力流体阀， 流体真空喷射器 引出有一真空吸管， 真空吸管的引出端与所述的输送泵上的排气孔气密性连接， 真空吸管上装设有真空电磁阀。
上述流体增压机为一级或多级风机， 也可为单级或多级蜗轮机； 还可为单 级或多级回转动力泵， 更可为容积式压缩机。
上述流体喷射引流装置的动力流体为气体或液体。
其工作原理是：
启动， 自动控制系统， 启动流体喷射引流装置内置的流体增压机 （或打开 外供压力流体源阀门）， 流体喷射引流装置与输送泵间连接的真空电磁阀开启。 流体真空喷射器制造的真空通过吸气管传导至输送泵腔， 输送泵内空气通过吸 气管流向流体真空喷射器排出。 此时低位介质在大气压力作用下沿泵吸入管进 入输送泵腔。 输送泵设置的液位传感器发出信号至自动控制箱， 自动控制箱指 令关闭真空电磁阀。 停止流体增压机 （或关闭外供压力流体阀门）， 输送泵启动 运行。 介质在输送泵作用下送向输出管。
本发明具有如下优点：
1、 吸排低位介质时， 不用自灌式安装， 首次使用亦无需人工向泵内注水或 引水， 开机即可排出介质。 适合远离水源或不易引流 （与水混合有反应） 的介 质。
2、 泵停机后， 吸入管及泵腔内无残留介质， 无需对泵及吸入管采取保温措 施， 完全适用于冬季， 特别是高寒地区无保温工况下安装使用。
3、 用于输送污水、 泥浆水及料浆时， 无需反冲洗。
4、 可取消低位泵房或高位水池的基础建设， 液面上方安装， 重心底、 体积 小， 节省投资及占地， 且检修方便。
5、 无浸蚀， 除过流部件外， 其余部分与介质不接触。 整机运行寿命是自吸 泵液下泵、 潜污泵的 5— 10倍。
6、 无需底阀， 吸入损失小， 效率高。
7、 本泵除具备高液位起动低液位停机功能外， 而且还具有智能保护停机装 置， 在介质吸空后自动停机， 可实现远程控制， 节省电和人力、 物力。
8、 根据工况环境可选择立式、 卧式、 移动或固定式安装。
9、 效率普遍提高 3%— 5%， 比传统无密封自控自吸泵效率高 10%— 30%， 节能效果非常明显。
