Problems solved by technology

The collision between the blades is not only easy to cause the friction damage of the blades, but also may exceed the limit of the material of the scroll parts and cause the blades to break
In addition, when the scroll compressor runs at high speed, the collision between the blades is intensified, which increases the overturning moment of the movable scroll part, which leads to the overturning of the movable scroll part, which greatly affects the performance of the scroll compressor and operational reliability
[0005] The development of technology has higher and higher requirements for the speed of the scroll compressor, and the serious collision between the blades of the existing scroll compressor under high-speed operation has become the main factor limiting the speed increase of the scroll compressor

Abstract

The invention provides a scroll compressor. The scroll compressor comprises a fixed vortex part, a movable vortex part, a main bearing seat and a blocking structure, wherein the fixed vortex part comprises a fixed vortex end plate and fixed vortex blades; the movable vortex part comprises a movable vortex end plate, movable vortex blades and a hub part; the main bearing seat supports the movable vortex part and is provided with a concave part used for accommodating the hub part of the movable vortex part; and the blocking structure blocks the movable vortex part during the motion process of the movable vortex part to reduce or prevent collision between the fixed vortex blades and the movable vortex blades. According to the scroll compressor, collision between the fixed vortex blades and the movable vortex blades during the motion process of the movable vortex part is effectively reduced or avoided, damage to the blades is reduced or avoided, the risk of vortex overturning is reduced, and performance and reliability of the scroll compressor are improved.

Description

technical field [0001] The present invention relates to a scroll compressor. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art. [0003] A scroll compressor generally includes a housing, a compression mechanism housed in the housing, a rotary shaft, a driving mechanism, a main bearing housing, and the like. Wherein, the compression mechanism includes a fixed scroll component and a movable scroll component. The drive mechanism includes a stator and a rotor. The fixed scroll part is fixed in the casing, and the movable scroll part is supported in the casing through the main bearing seat. The rotating shaft passes through the rotor and is driven to rotate by the rotor. Usually, an eccentric crank pin is arranged at one end of the rotating shaft, and the eccentric crank pin extends into the hub of the orbiting scroll, so that the orbiting scroll is further driv...
