Problems solved by technology

However, the oil-free compressor not only has no lubricating oil cooling, but also increases heat production due to the increase of friction loss, so an external cooling system is needed to ensure that the overall temperature of the system is maintained at a certain level

Embodiment 1

[0020] The main components of the water-cooled oil-free scroll compressor of the present invention include a fixed scroll 2 and a movable scroll 3. When the compressor is working, the motor 6 drives the main shaft 5 to drive the movable scroll 3 to compress, and the main shaft 5 is installed on the main shaft bearing 10 superior. The cooling system works at the same time, and the cooling water circulates to cool the fixed scroll 2 and the movable scroll 3 . Cooling water enters the static scroll cooling channel 8 on the back side from the static scroll inlet pipe 1, and flows out of the static scroll 2 through the static scroll outlet pipe 7 after the cooling water exchanges heat with the static scroll 2. Another stream of cooling water flows from the dynamic and static joint 4 of the scroll at the water inlet end into the movable scroll cooling channel 9 on the back, and the cooling water exchanges heat with the movable scroll 3 and flows out of the movable scroll 3 through t...

Embodiment 2

[0022] The main parts of the water-cooled oil-free scroll compressor of the present invention include a fixed scroll 2 and a moving scroll 3, and the fixed scroll 2 and the moving scroll 3 extend the scroll base laterally outside the scroll wall, so that the moving scroll can 3 and the static scroll 2 are provided with a scroll dynamic joint 4 at the water inlet end and a scroll dynamic joint 11 at the water outlet end. When the compressor is put into operation, the motor 6 drives the main shaft 5 to drive the movable scroll 3 to compress, and the main shaft 5 is installed on the main shaft bearing 10 . The cooling system works at the same time, and the cooling water circulates to cool the fixed scroll 2 and the movable scroll 3. The cooling water enters the water distribution port of the static scroll 2 from the static scroll inlet pipe 1, and the cooling water is divided into two streams, one along the The static scroll cooling channel 8 on the back flows, exchanging heat wi...

Abstract

The invention relates to a vortex-disc movable-static connector and a water-cooling non-oil scroll compressor. The connector comprises a movable sealing block, a static sealing block, a supporting part, a spring and an internal water pipe; the movable sealing block can move horizontally along with a vortex disc, the static sealing block is connected with the end face of the movable sealing block,the static sealing block, the supporting part and the spring sleeves the internal water pipe in sequence, one end of the spring is fixed, the pressure of the other end of the spring is applied to thestatic sealing block through the supporting part, and the static sealing block and the movable sealing block are pressed; cooling water is introduced to a movable vortex-disc cooling water channel ona movable vortex disc through the internal water pipe, and the outer wall of the internal water pipe is sealed. The movable vortex-disc cooling water channel of the water-cooling non-oil scroll compressor is communicated with a static vortex-disc cooling water channel through the vortex-disc movable-static connector, or water inlet and outlet are conducted by the internal water pipe separately, after the vortex-disc movable-static connector is adopted, when the non-oil scroll compressor is designed, the structural form and part distribution of the scroll compressor can be considered to selectdifferent water circulation modes, and the application range is wide.

Description

technical field [0001] The invention relates to the field of compressors, in particular to a scroll dynamic and static joint and a water-cooled oil-free scroll compressor. Background technique [0002] Due to its excellent force balance performance, high efficiency, compact structure, low noise and low vibration, scroll compressors have great advantages in many aspects compared with traditional compressors, so scroll compressors have always been used widely used. In recent years, due to the emphasis on environmental protection in various countries and the improvement of air quality requirements in food, medical and other fields, the general oil separation system cannot guarantee the required air quality, so oil-free scroll compressors must be selected, but there is no The oil-lubricated scroll compressor must face three problems, the first is the lubrication problem, the second is the sealing problem, and the third is the cooling problem. Lubrication problems can be solved...
