摘要： A conical member for a pump head of a liquid ring pump, the conical member including a body, the body defining a first body opening on a first end positioned to abut a first pump opening, a second body opening on the first end positioned to abut a second pump opening, and a port. The conical member further includes a radially outer lip arranged about the first end and positioned to abut a pump aperture. A sealing liquid introduction path is arranged to introduce sealing liquid to a working chamber, the sealing liquid introduction path arranged at least partially between the second body opening and an outlet, and a gas vent passage is arranged to vent gas from the working chamber, the gas vent passage arranged at least partially between the port and the first body opening.

摘要： A liquid ring pump includes a port plate coupled to a pump head. The port plate has an opening with a first end at a first section and a second end at a second section. The first section opens through a portion of a surface forming a first face of the port plate. The second section opens at the second end into a shaft receiving aperture of the port plate. The first and second sections are continuous. The first section is angularly between the closing edge of a port plate outlet and leading edge of a port plate inlet. A length measured from the first section to the inlet's leading edge is less than a length measured from the first section to the outlet's leading edge. The first section does not open into the outlet or inlet.

摘要： A modular liquid ring pump has a liquid ring overload protection system including a passage from a working chamber directly to the pump discharge passage and a mechanical relief valve configured to release liquid from the working chamber during compressor overload. The liquid ring pump, when configured to have two stages, has an inter-stage by-pass system that includes an opening in an inter-stage passage and a pressure sensitive mechanical valve that allows the discharge of a first stage compressor to flow directly to the pump discharge at start up or during low pressure operation. The liquid ring pump's modular construction may be easily configured from a single stage pump to a two-stage pump and vice versa by using the same bearings, head, and drive system and only changing the body, cone, and rotor.
摘要翻译：模块化液环泵具有液环过载保护系统，其包括从工作室直接通向泵排出通道的通道和构造成在压缩机过载期间从工作室释放液体的机械安全阀。液环泵当被配置成具有两个级时，具有一个跨级旁通系统，该系统包括一个级间通道中的一个开口和一个压力敏感的机械阀，允许第一级压缩机的排放直接流向泵在启动时或在低压运行期间排出。液环泵的模块化结构可以通过使用相同的轴承，头部和驱动系统，并且仅改变主体，锥体和转子，从而将单级泵容易地配置成两级泵，反之亦然。

摘要： A liquid ring pump includes a planar port plate having first and second planar walls, a sidewall which defines a shaft receiving aperture, an inlet, and an outlet. An opening is formed in the port plate and includes an open end that extends through the sidewall and an open face that extends through the first planar wall. A rotor shaft is rotatable about a central axis and is positioned such that a portion of the rotor shaft extends into the shaft receiving aperture. An aperture is formed in the port plate and positioned substantially opposite the opening. The opening, a space defined between the rotor shaft and the sidewall, and the aperture, cooperate to define a channel that extends between a first side of the shaft receiving aperture and a second side of the shaft receiving aperture, wherein the channel is formed entirely coplanar with the port plate.
