Problems solved by technology
When the thickness of the roller is relatively thin, the high-pressure refrigerant inside the roller leaks seriously to the low-pressure area outside the roller, thereby reducing the cooling capacity of the compressor, increasing the power consumption of the compressor, and affecting the energy efficiency of the compressor

The invention provides a pump body structure, a compressor and an air conditioner. The pump body structure comprises a crankshaft (1), a roller (2) and a flange, the crankshaft (1) comprises an eccentric part (3), the eccentric part (3) is sleeved with the roller (2), the adjacent area of an inner hole of the roller (2) is filled with a solid structure (4), the solid structure (4) is located on the axial outer side of the eccentric part (3), and the end face of the solid structure (4) is in sealing fit with the end face of the flange, the circle center angle, occupied by the solid structure (4) in the circumferential direction, of the eccentric part (3) is 3 / 5 or more of the whole circle angle. According to the pump body structure, the compressor and the air conditioner, the sealing effect of the roller can be guaranteed, leakage of refrigerants from the inner hole of the roller to the outer circle of the roller is effectively reduced, and the energy efficiency of the compressor is improved.
Description
technical field [0001] The present application relates to the technical field of air conditioning, in particular to a pump body structure, a compressor and an air conditioner. Background technique [0002] In the existing design of the pump body, the small cylinder height and small bore are important routes to improve the efficiency of the pump body. However, in the optimization process of small cylinder diameter and small cylinder height, the thickness of the rollers is generally designed to be thinner, and the operation process of the compressor In the model, the cavity in the inner hole of the roller communicates with the high-pressure cavity in the housing through the oil passage hole of the crankshaft, so the inner hole of the roller is a high-pressure area, and its pressure can be considered to be equivalent to the exhaust pressure, while the pressure distribution in the outer circle of the roller is complicated , which is adjacent to the suction chamber, it can be con...
