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

The disclosure discloses a pump body and a compressor with the pump body. The pump body includes: a flange structure; a bearing, the bearing being provided with an inner ring and an outer ring, the inner ring being rotatably disposed on the flange structure, and an end face of the inner ring being abutted against a contact face of the flange structure; and an oil guide channel provided inside a side wall of the inner ring, or inside the flange structure, or the side wall of the inner ring and inside the flange structure, an outlet of the oil guide channel being positioned between the end face of the inner ring and the contact face of the flange structure, so as to introduce lubricating oil between the end face of the inner ring and the contact face of the flange structure.

Pump body with oil guide channel for lubricating between the end face of the inner ring and the contact face of the flange structure

The present disclosure relates to an oil line structure of a compressor and compressor, wherein the oil line structure of a compressor including: a spindle, an upper flange and a rolling bearing, wherein an interior of the rolling bearing encloses a cylinder cavity for performing compression, and the rolling bearing comprises a rolling body; wherein the spindle is internally provided with a spindle oil hole, and the upper flange is provided with an upper oil groove which is in communication with the spindle oil hole to guide an oil into the rolling body so as to lubricate the same. In this way, the heat generated by friction of the rolling body is discharged in time, so as to prevent a temperature rise in the bearing and reduce the wear, thereby improving the energy efficiency value of the compressor and ensuring normal operation of the compressor.

Oil line structure of compressor and compressor

Disclosed are a cylinder, a pump body assembly, a compressor, and a temperature adjusting device. The cylinder includes a cylinder body, and a first cavity and a second cavity are formed in an axial direction of the cylinder body, wherein the first cavity is in communication with the second cavity, and an inner diameter of the first cavity is greater than that of the second cavity; and when the cylinder body operates, the first cavity forms a first working cavity, and the second cavity forms a second working cavity. With such an arrangement, multiple working cavities are formed inside one cylinder body, which simplifies an installation process of the pump body assembly, and enables a pump body with the cylinder to be installed more conveniently and easily, thereby improving installation reliability of the pump body assembly.

Cylinder, pump body assembly, compressor, and temperature adjusting device

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.
