Abstract

本实用新型涉及一种射流式自吸离心泵，接口座5进口轴向开有二半圆形槽，径向有螺纹接口，通过出口外螺纹分别与锥形喷嘴4、收缩形收集管3连接，组成射流器，通过收缩形收集管3的法兰接入自吸离心泵2的进口，组成射流式自吸离心泵。通过外部管路把泵2进口与接口座5径向螺纹接口相连，接口座5法兰与吸入管路相连。当泵2工作时，出口部分高压液体经接口座5径向螺纹接口通入，进入锥形喷嘴4，形成高速液流，吸入管路液体经接口座5进口轴向二半圆形槽，随同高速液流一同进入收缩形收集管3相连的泵2进口，在泵2进口产生一定正压，从而避免了汽蚀。

Description

射流式自吸离心泵
所属技术领域
本实用新型涉及一种射流式自吸离心泵
背景技术
目前自吸离心泵广泛应用于火车卸槽、码头卸油、油船货油等场合，随着石化行业的快速发展，油库规模扩大。如火车卸槽，随着火车鹤位的增加，进口管线增长，吸入条件变坏，泵在工作时容易产生汽蚀，或自吸困难，影响泵的正常工作。
为改善使用条件，提高使用效果，提出了射流式自吸离心泵。
发明内容
本实用新型的目的是提供一种射流式自吸离心泵，用于火车卸槽、扫仓、码头卸油。
本实用新型的目的是这样来实现的：接口座5进口轴向开有二半圆形槽，径向有螺纹接口，通过出口外圆螺纹分别与锥形喷嘴4、收缩形收集管3连接，组成射流器，通过收缩形收集管3的法兰接入自吸离心泵2的接口，组成射流式自吸离心泵。通过外部管路把泵2出口与接口座5径向螺纹相连，当泵2工作时，出口的部分高压液体从接口座5径向螺纹接口通入，进入锥形喷嘴4时，由于出口通道变小，形成高速液流，在大气压作用下，吸入管液体经接口座5进口轴向二半圆形槽，随同高速液流一同进入收缩形收集管3相连的泵2进口，在泵2进口产生一定的正压，从而避免了汽蚀。
附图说明：
图1本实用新型射流式自吸离心泵
具体实施方案
图1所示，接口座5进口轴向开有二半圆形槽，径向有螺纹接口，通过出口外螺纹接口分别与锥形喷嘴4、收缩形收集管3连接组成射流器，通过收缩形收集管3的法兰接入自吸离心泵2的进口，组成射流式自吸离心泵。当泵2工作时，部分高压液体从接口座5径向螺纹接口通入，进入锥形喷嘴4，由于过流面积变小，形成高速液流，吸入管路液体经接口座5进口二半圆形槽，随同高速液流一同进入收缩形收集管3相连的泵2进口，并产生一定的正压，从而避免汽蚀的产生。
