The present disclosure provides a pumping assembly, a compressor and air conditioning equipment. The pumping assembly includes a first structural body, a rolling bearing assembly, a second structural body, a third structural body and a main shaft passing through the first structural body, the rolling bearing assembly, the second structural body and the third structural body. The pumping assembly includes: a first lubricating oil path passing through a second structural part, the sliding sheet backpressure cavity, a third structural part, a second structural part and a rolling body of the rolling bearing assembly; a second lubricating oil path passing through the sliding sheet backpressure cavity and a first pressure relieving groove of the first structural body; and a third lubricating oil path passing through the sliding sheet backpressure cavity, the first structural part and the rolling body of the rolling bearing assembly.

Pumping assembly, compressor and air conditioning equipment

Some embodiments of the disclosure disclose a bearing assembly and a compressor with the bearing assembly. The bearing assembly includes: a retainer assembly (), a bearing stationary ring (), and a bearing rotary ring (). The retainer assembly () is disposed between the bearing stationary ring () and the bearing rotary ring (). A lubrication passage is provided in an end face of the bearing rotary ring ().

Bearing assembly and compressor with bearing assembly

A rotary cylinder piston compressor pump is provided, including a rotating shaft (), a piston () and a cylinder (). A rotating shaft hole () is provided in the rotating shaft (). An oil guiding channel, provided in the cylinder (), communicating with the rotating shaft hole (). A recess () is formed in the inner end face of the cylinder (). An oil path () sealed relative to a compression cavity () of the cylinder () is formed between the recess () and the piston (). The oil path () between the recess () and the piston () is communicated with an oil path () between the piston () and the rotating shaft () and is communicated with the oil guiding channel by means of an oil returning channel. Also provided is a compressor including the compressor pump.

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.

A compressor includes two parallel arranged primary cylinders and a secondary cylinder arranged in the downstream of the two primary cylinders. The secondary cylinder includes a cylinder body and a sliding vane. The sliding vane is arranged inside the cylinder body. A locking part is used for locking and unlocking the sliding vane. The locking part is clamped with and separated from the sliding vane. When the sliding vane is in the locking position, the sliding vane is locked in a seal cavity inside the secondary cylinder, and the locking end of the locking part extends to the side at which the secondary cylinder is located. The compressor can be switched between a single-stage mode and a double-stage mode. In the condition of light load, energy efficiency can be improved and the waste of energy sources is avoided. An air conditioning system and compressor control method are also disclosed.
