Abstract
The invention provides a vertical rotary compressor. The vertical rotary compressor comprises a shell, a crankshaft, a rotor and an upper cylinder cover; the crankshaft is contained in the shell, andthe crankshaft is provided with a long shaft part, an eccentric part and a short shaft part which are sequentially connected from top to bottom; the rotor is arranged at the upper end of the long shaft part of the crankshaft in a sleeving mode, the upper cylinder cover comprises a bearing part and a flange part, the bearing part is arranged at the lower end of the long shaft part of the crankshaftin a sleeving mode, and the flange part extends outwards by taking the bearing part as a circle center; and a first magnetic pole is fixed to the lower end face of an iron core of the rotor, a secondmagnetic pole is fixed to the upper end face of the bearing part of the upper cylinder cover, the first magnetic pole and the second magnetic pole are the same poles and opposite to generate interactive repulsive force, and resultant force of motor magnetic core height difference axial force, skewed slot force axial force, rotor self-weight and crankshaft self-weight is counteracted to reduce thepressure between a thrust surface and a lower cylinder cover, so that the abrasion is reduced, the pump body mechanical efficiency is improved and the compressor performance coefficient is increased.
Description
technical field [0001] The invention relates to the technical field of air conditioning, in particular to a vertical rotary compressor. Background technique [0002] In a rotary compressor, due to the resultant force of the axial force of the height difference of the motor core, the axial force of the chute force, the self-weight of the rotor and the self-weight of the crankshaft, the lower cylinder head is pressed through the lower thrust surface of the crankshaft. The greater the resultant force, the greater the resultant force of the crankshaft The wear of the contact surface between the lower thrust surface and the lower cylinder head is greater. Long-term wear leads to a decrease in the mechanical efficiency of the pump body and a decrease in the COP (coefficient of performance, coefficient of performance) of the compressor. [0003] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of...
