Description

Vertical compressor that oils fast

[ technical field ] A method for producing a semiconductor device

The utility model relates to a compressor technical field especially relates to a vertical compressor who oils fast.

[ background of the invention ]

The compressor generally includes a hermetic casing, a compression pump body, a motor assembly, a crankshaft, a gas-liquid separator, a suction pipe, and a discharge pipe. The stator and the rotor form a motor component of the compressor, and the compression pump body comprises a cylinder, an upper flange, a lower flange and a roller fixed on the eccentric part of the crankshaft. When the rotor rotates in the stator during working, the roller is driven by the rotating shaft to roll eccentrically in the cylinder, and under the eccentric rolling action of the roller, a low-pressure refrigerant is sucked into the cylinder through the air suction pipe to be compressed until the pressure exceeds the critical pressure, and then the low-pressure refrigerant is output to the heat exchange system through the exhaust pipe.

The compressor has the advantages that the refrigerating oil is stored at the bottom in the closed shell of the compressor, the crankshaft is internally provided with an engine oil channel which is communicated up and down, in the working process of the compressor, the refrigerating oil can reach the positions of all parts in the compressor through the engine oil channel in the crankshaft and the oil hole communicated with the engine oil channel so as to achieve the purpose of lubricating the parts, the starting performance and the service life of the compressor are closely related to the lubricating effect, the more sufficient the lubrication is, the easier the compressor is started, and the longer the service life of the compressor is. When the refrigeration compressor starts to work, the crankshaft rotates at a high speed, and the refrigerant oil at the bottom of the compressor shell is supplied to the spiral oil groove in the middle section through the connecting hole in the tail section of the crankshaft under the action of centrifugal force, so that the lubricating effect of the moving part is realized. However, when the compressor starts to work, before the rotating speed of the crankshaft is not high enough, the moving parts of the movement are dry and are not lubricated by lubricating oil, so that the starting friction resistance is large, the starting is difficult, and therefore a large starting torque is required for the motor in the compressor. Meanwhile, because the lubricating function of lubricating oil is not available for a long time after starting, the compressor is easy to cause serious abrasion, and the service life of the compressor is shortened.

The utility model discloses it is not enough to solve prior art and research and propose.

The utility model discloses can realize through following technical scheme:

the utility model discloses a vertical compressor capable of oiling rapidly, which comprises a shell, an upper shell, a lower shell and a crankshaft, the shell, the upper shell and the lower shell form an inner cavity of the compressor, an oil pool is arranged at the bottom of the inner cavity of the compressor, a stator winding is arranged on the inner wall of the shell in a surrounding manner, a long shaft is vertically arranged in the middle of the stator winding, the crankshaft is fixed on the outer periphery of the lower end of the long shaft, a rotor is also fixedly arranged on the outer periphery of the long shaft, the rotor is arranged between the stator winding and the outer periphery of the long shaft, the bottom of the long shaft is arranged in the oil pool, an oil duct which penetrates through the long shaft is arranged in the long shaft, the periphery of the long shaft is also provided with an oil groove which is connected with the oil duct through a plurality of blind holes, the long shaft is characterized in that a connecting groove is formed in the upper end of the long shaft, the bottom of the connecting groove is connected with the oil duct, and spiral blades are arranged on the inner wall of the connecting groove in an encircling mode. The major axis is at stator winding internal rotation during compressor operation, the inside spiral leaf of spread groove is rotatory along with the major axis on the major axis, because the spiral leaf is rotatory, linear motion that spiral leaf rotary motion accompanies promotes the material and carries forward, so the inside air of spread groove moves toward major axis top when the spiral leaf is rotatory, the inside air of oil duct is gradually taken out and is separated, the inside negative pressure that forms of oil duct, the inside lubricating oil of oil bath is because the negative pressure effect, rise fast, the function of oiling fast in the oil duct has been realized, the inside lubricating oil of oil duct is along with in the oil groove of blind hole arrival major axis outer wall, provide lubricating oil for each part of compressor through the oil groove, thereby avoid compressor internals wearing and.

Preferably, the oil groove is circumferentially provided on an outer peripheral side of the long axis. The oil groove is arranged on the outer periphery side of the long shaft in a surrounding mode, so that oil is applied to all parts more uniformly.

Preferably, an exhaust pipe penetrating through the upper case is fixed to the upper case.

Compared with the prior art, the utility model has the advantages that:

promote the inside air of spread groove and move toward major axis top during the spiral leaf is rotatory, the inside air of oil duct is taken out gradually and is separated, the inside negative pressure that forms of oil duct, and the inside lubricating oil of oil bath rises fast owing to the negative pressure effect, has realized the function that oils fast in the oil duct, has avoided the long-time work of major axis not to have the phenomenon of lubricating oil in the pivot, has prolonged the life of compressor.
