一种集成滑阀的单螺杆膨胀机
摘要：
一种集成滑阀的单螺杆膨胀机，属于余热余压能源回收利用技术领域。一种集成滑阀的单螺杆膨胀机，包括壳体、主轴、单螺杆转子、星轮滑阀等，壳体上设置中心对称布置的吸气滑阀调节装置和内容积比滑阀调节装置，吸气滑阀调节装置、转子与星轮片之间形成相应的吸气腔，内容积比滑阀调节装置、转子与星轮片之间形成相应的排气腔。本单螺杆膨胀机解决了变工况下单螺杆膨胀机效率低及转速不稳定的技术问题。
摘要（英）：

The invention provides a single-screw expander integrated with sliding valves and belongs to the technical field of recycling of waste heat, excess pressure and energy. The single-screw expander integrated with sliding valves comprises a shell, a main shaft, a single-screw rotor and star wheel sliding valves, wherein an air suction sliding valve adjusting device and an interior volume specific ratio sliding valve adjusting device are arranged on the shell in a center symmetry arrangement manner; corresponding air suction cavities are formed between the air suction sliding valve adjusting device, the rotor and star wheel sheets; corresponding exhaust cavities are formed between the interior volume specific ratio sliding valve adjusting device and the star wheel sheets. Through the single-screw expander, the technical problems of low efficiency and unstable rotation speed of the single-screw expander under variable conditions are solved.
