For existing oil-free scroll compressor, the air-cooled heat radiation of general employing, usually adorn a wind wheel at the main shaft end, wind wheel is given moving price fixing cooling simultaneously when scroll compressor is worked, the cooling of this mode is limited, because scroll compressor can constantly produce heat when doing not stopping work, and this heat can be long more and high more along with the operating time, and the rotating speed of wind wheel is constant.Though this radiating mode makes the price fixing cooling to a certain extent, it is satisfactory that the gas-solid heat exchange method has determined that its heat exchange efficiency still is difficult to.
Summary of the invention
The utility model is at above-mentioned the deficiencies in the prior art, a kind of water-cooled scroll compressor is provided, its moving price fixing all has cooling water to pass through, scroll compressor is when work like this, the heat that produces will be by taking away by the cooling liquid on Moving plate and the price fixing, and the flow velocity of cooling liquid can be regulated according to cool effect simultaneously.
Concrete technological scheme of the present utility model is:
A kind of oil-free scroll compressor, comprise frame, Moving plate, price fixing, main shaft and eccentric shaft, described Moving plate and price fixing are installed in the frame, Moving plate and price fixing are formed compression chamber, main shaft drives Moving plate and does plane motion, compression enters the medium of compression chamber, it is characterized in that described compressor comprises the airtight cooling cabin of being made up of Moving plate and pallet, the liquid circulation cooling cabin of flowing through.
Described cooling cabin is provided with cooling liquid turnover mechanism, by be fixed in the movable valve plug between pallet and the Moving plate, auxilliary spool and the airtight cooling tube that is installed between movable valve plug and the auxilliary spool that is fixed on the frame formed, the movable valve plug follower disk moves and moves.
Described compressor comprises the cooling chamber of being made up of price fixing and price fixing lid thereof, and price fixing covers and is provided with the cooling liquid import and export.
Described pallet and Moving plate are provided with the valve core frame that matches with movable valve plug, and movable valve plug is connected in the valve core frame.
Fixedly connected with movable valve plug is airtight in the end that described cooling tube links to each other with movable valve plug, the other end of cooling tube and the airtight flexible connection of auxilliary spool.
Described cooling cabin and cooling chamber set liquid tank and the oil hydraulic pump of circulation kinetic energy are provided, and the connecting tube that has heat sinking function concurrently connects liquid tank, oil hydraulic pump, cooling liquid turnover mechanism and cooling liquid and imports and exports.
When the utility model oil-free scroll compressor operating, the driven by motor main shaft rotates, main shaft drives Moving plate and does plane motion, eccentric shaft plays position-limiting action, simultaneously, compressed media enters compression chamber by the medium import, will hang down piezodielectric and change high-pressure medium into, discharge compression chamber by one-way valve simultaneously and enter container, enter container thereby endlessly compressed media is become high pressure from low pressure.
In this compression process, the temperature of Moving plate and price fixing can constantly raise, in the time of the work of driven by motor Moving plate, cooling liquid is through the oil hydraulic pump supercharging, the cooling liquid that covers through cooling liquid turnover mechanism and price fixing enters cooling cabin and cooling chamber, flow back to tank for coolant again, the circulation by cooling liquid reaches the cooling to Moving plate and price fixing.
