A compressor pump structure comprises a rotating shaft, a piston, a cylinder, a cylinder sleeve, a lower flange and an upper flange, the central axis of the rotating shaft being arranged eccentrically with respect to the central axis of the cylinder, the rotating shaft being slidably arranged in the piston, the piston being movably arranged in the cylinder and forming two volume-variable chambers with the cylinder, the piston comprising two first sliding planes arranged opposite one another and two first contacting planes arranged opposite one another, the first contacting plane on the upper side being in sealing contact with the upper flange, and the first contacting plane on the lower side being in sealing contact with the lower flange. Also disclosed is a compressor with the compressor pump structure.

Compressor pump structure and compressor

A fluid machine, heat exchanger, and operating method of fluid machine. The fluid machine includes: a rotation shaft (), a cylinder (), and a piston assembly (). The rotation shaft () and the cylinder () are eccentrically disposed relative to each other and an eccentric distance is fixed. The piston assembly () has a variable volume chamber (). Because the eccentric distance between the rotation shaft () and the cylinder () is fixed, the rotation shaft () and the cylinder () rotate about their respective axes thereof during motion and the position of center of mass remains unchanged, so that the piston assembly () is allowed to rotate stably and continuously when moving in the cylinder (); and vibration of the fluid machine is mitigated, a regular pattern for changes in the volume of the variable volume cavity is ensured.

Fluid machinery, heat exchange equipment, and operating method for fluid machinery

A fluid machinery, a heat exchange equipment, and an operating method for the fluid machinery. The fluid machinery includes: an upper flange (); a lower flange (); a cylinder (); a rotating shaft (), the axis of the rotating shaft () being eccentric to the axis of the cylinder () and at a fixed eccentric distance; and a piston component (), the piston component () being provided with a variable volume cavity (). Because the eccentric distance between the rotating shaft () and the cylinder () is fixed, the rotating shaft () and the cylinder () rotate around the respective axes thereof during motion, and the position of the center of mass remains unchanged, so that the piston component is allowed to rotate stably and continuously when moving within the cylinder (); and vibration of the fluid machinery is effectively mitigated.
