Abstract

新型干式潜水电泵,属泵类。该电泵有一个和电机内腔相连通的柔性气囊,当电泵下潜时,气囊内气体受压,进入电机腔内,腔内压强升高并和外界液体压强相等,使得外部液体难以泄漏到电机内腔。

Description

新型干式潜水电泵
本实用新型属于泵类。
以前的干式潜水电泵,下潜不能太深,太深会使电机内外压强差过大,容易进水。有不少人研究改进干式潜水电泵,但他们的着眼点都集中在如何制造高性能的密封件上,而对电机内外的压强差这个造成电机内进水的根本原因却很少关注。所以,在干式潜水电泵的发展上,至今没有重大突破。
本实用新型的目的,是提供一种能消除潜水电机内外压强差的新型干式潜水电泵。
本实用新型的任务是这样实现的:在干式潜水电泵上增加一个和电机内腔相连通的柔性气囊,气囊内充入一定气体,当电泵潜入水中时,气囊体积变小,压强增大,由于电机内腔和气囊相连通,压强也随着增大,结果和外部水的压强相同,这就消除了电机内外的压强差。气囊外加一护罩用来保护气囊不受损伤。电机上还要加一个补气阀,用来在电泵使用前或检修时向电机内、气囊内补气。
本实用新型的优点是:无论电泵下潜多深,电机内腔和外部水的压强始终相等,外部的水不具有向电机内腔泄漏的动力,很难进入电机内部。
附图是本实用新型的部分剖视图,主要包括泵(1)、电机(2)、补气阀(3)、连通孔(4)、护罩(5)、气囊(6)。
本实用新型的典型实施例如附图所示,在电机(2)的下端,连接一个气囊(6),在气囊(6)与电机内腔之间,开一连通孔(4),补气阀(3)装在电机(2)上。气囊(6)的体积由设计下潜深度而定,一般地说,在水中每下潜10米,气囊体积的增加是电机内腔容积的1倍。

Claims (3)

1.新型干式潜水电泵,主要包括泵和电机,其特征足在电泵外有和电机内腔相连通的柔性气囊。
2.如权利要求1所说的新型干式潜水电泵,其特征是气囊外有一护罩。
3.如权利要求1或2所说的新型干式潜水电泵,其特征是在气囊上或电机上有一个补气阀。
