Embodiment Construction

[0037] Such as Figure 4-6 As shown, the present invention provides an oil supply device, including a rotating part 2, a back pressure oil pool arranged at the lower end of the rotating part 2, and a back pressure oil pool arranged inside the rotating part 2 and capable of communicating with the back pressure The oil supply passage 15 between the oil pool and the upper end surface of the rotating part 2, and the oil supply passage 15 arranged in the oil supply passage 15 can be controlled to open, close or close the oil supply passage 15 according to the speed of the rotating part 2 A control mechanism that adjusts the size of the conduction opening.

[0038] Through the control mechanism provided in the oil supply passage of the present invention that can control the oil supply passage to be turned on, closed or adjust the conduction opening according to the size of the rotational speed of the rotating component, it can be used especially for scroll compressors. The amount o...

Abstract

The invention provides an oil supply device. The oil supply device comprises a rotary part (2) and a back pressure oil pool (21) arranged at the lower end of the rotary part (2) and further comprises an oil supply channel (15) which is arranged in the rotary part (2) and can communicate the back pressure oil pool (21) with the upper end face of the rotary part (2) and a control mechanism which is arranged in the oil supply channel (15) and can control opening and closing of the oil supply channel (15) or adjust the opening degree of the oil supply channel according to the rotary speed of the rotary part (2). By means of the oil supply device, the oil supply amount of especially the scroll compressor can be controlled; the oil supply amount can be adjusted according to the rotary speed of the rotary part, especially the rotary speed of a kinetic scroll plate of the scroll compressor; therefore, the oil supply device does not need applying of driving force, and the opening and closing of the oil supply channel can be achieved by means of the speed change of the rotary part. The invention further relates to the scroll compressor with the oil supply device and a control method.

Description

technical field [0001] The invention belongs to the technical field of compressors, and in particular relates to an oil supply device, a scroll compressor with the same and a control method. Background technique [0002] Generally speaking, a scroll compressor is composed of a closed casing, an orbiting scroll, a fixed scroll, a crankshaft, a frame, an anti-rotation mechanism, and a motor. The profiles of the movable and static scrolls are both spiral, and the movable scroll is eccentrically installed relative to the static scroll with a difference of 180 degrees. point contact), the end of the scroll body shape line is in contact with the bottom of the opposite scroll body, so a series of crescent-shaped spaces are formed between the moving and static scroll disks, that is, the volume of the element. When the movable scroll takes the center of the static scroll as the center of rotation and performs non-rotation-translational motion with a certain radius of rotation, the c...
