摘要： Disclosed herein is a sliding vane pump for providing positive displacement of a fluid such as water. The pump comprises a pump assembly having a housing with a fluid inlet and a fluid outlet formed therein, a lining member received in the housing and defining a substantially cylindrical inner surface and a rotor arranged inside the lining member to rotate about a rotational axis. The rotor defines a substantially cylindrical outer surface such that the inner surface of the lining member and the outer surface of the rotor define a working space therebetween, the working space having a radial cross-sectional area which varies about the rotational axis. The pump assembly also comprises a plurality of vanes received in substantially radial slots formed about the outer surface of the rotor. Each of the vanes is arranged to slide in the radial direction with respect to the rotor such that an outer edge of the vane contacts the inner surface of the lining member, thereby dividing the working space into working chambers. In use, rotation of the rotor draws the fluid from the fluid inlet into the working chambers and ejects the fluid from the working chambers into the fluid outlet. The vanes are formed of a carbon graphite or ceramic material and the rotor is formed of a ceramic material, which provides reduced thermal expansion compared to convention materials such as stainless steels. A base portion of each of the slots of the rotor is enlarged and has a rounded cross-sectional shape. The pump assembly further comprises a strainer assembly received into an opening in the housing and extending across the fluid inlet for filtering particulate matter from the fluid. The strainer assembly comprises a thermal sensor for sensing a temperature of fluid passing through the fluid inlet.
摘要翻译：本文公开了一种用于提供诸如水的流体的正位移的滑动叶片泵。泵包括具有壳体的泵组件，其具有形成在其中的流体入口和流体出口，衬套构件，容纳在壳体中并且限定基本上圆柱形的内表面和布置在衬套构件内部以绕旋转轴线旋转的转子。转子限定基本上圆柱形的外表面，使得衬里构件的内表面和转子的外表面在其间限定工作空间，工作空间具有围绕旋转轴线变化的径向横截面积。泵组件还包括多个叶片，其接收在围绕转子的外表面形成的基本上径向槽中。每个叶片布置成相对于转子在径向方向上滑动，使得叶片的外边缘接触衬里构件的内表面，从而将工作空间分成工作室。在使用中，转子的旋转将流体从流体入口吸入工作室，并将流体从工作室排出到流体出口中。叶片由碳石墨或陶瓷材料形成，并且转子由陶瓷材料形成，与诸如不锈钢的常规材料相比，其提供降低的热膨胀。转子的每个槽的基部被放大并且具有圆形的横截面形状。泵组件还包括容纳在壳体中的开口中并且延伸穿过流体入口的过滤器组件，用于从流体中过滤颗粒物质。过滤器组件包括用于感测通过流体入口的流体的温度的热传感器。
