Noise reduction type inner gearing double-screw pump

The utility model discloses a noise reduction type inner gearing double-screw pump, and belongs to the technical field of screw pump equipment. The oil injection ports are formed in the end covers on the two sides, lubricating oil can be injected into the end covers on the two sides through the oil injection ports, the lubricating oil can lubricate the internal meshing gear, meanwhile, the meshing gear is soaked in lubricating liquid, and the lubricating liquid can block noise generated in the rotating process of the meshing gear; the noise of the pump in operation is further reduced; the glue injection layer is arranged outside the shell, viscous oil can be injected in the manufacturing process of the pump due to the arrangement of the glue injection layer, and vibration and noise generated when the pump runs can be effectively restrained due to the arrangement of the viscous oil. 一种降噪型内啮合双螺杆泵，属于螺杆泵设备技术领域；通过在两侧的端盖上均设置一个注油口，注油口的设置可以对两侧的端盖内注入润滑油，润滑油的设置可以起到对内部啮合齿轮的润滑，同时将啮合齿轮浸于润滑液中，润滑液可以阻隔啮合齿轮旋转过程中产生的噪音，进一步的降低泵在
