Device, the outlet of water ring pump is connected with moisture trap by pipeline, the import of water ring pump is connected with condenser by pipeline, work
The working water side-entrance of water cooler is connected with moisture trap by pipeline, pipeline is passed through in the outlet of the water cooler that works respectively
It is connected in inlet pipeline and the water ring pump pump housing of water ring pump.The cooling water of work water cooler adopts double water source to design, i.e. working water
The cooling water side of cooler is ined succession two cooling water source inlet channels and water return pipeline respectively:Wherein one road water source is work water-cooled
But water-flow circuit realized by device and condenser, and another road water source is cooling water inlet pipe and the underground water pipe network of work water cooler
It is connected by water inlet pipe, valve, the CWR of work water cooler and a cooling tower are provided with this water inlet pipe
Connected by return pipe, valve is provided with this return pipe, is connected by pipeline between underground water pipe network and cooling tower, should
The gate valve of one regulatory function is provided with pipeline.
And, being achieved in that of water-flow circuit realized by described work water cooler and condenser:Work water cooler
Cooling water inlet pipe be connected with condenser recirculated cooling water water inlet pipe, in the work cooling water inlet pipe of water cooler and condensing
Valve, the return pipe of work water cooler and condenser cooling water return pipe are installed between device recirculated cooling water water inlet pipe
It is connected, between the return pipe and condenser cooling water return pipe of work water cooler, valve 6 is installed.
And, the water inlet pipe between the cooling water inlet pipe and underground water pipe network of work water cooler is provided with valve
With on the return pipe between the work CWR of water cooler and cooling tower, valve is installed.
And, between the outlet of described work water cooler and the inlet pipeline of water ring pump, restricting orifice is installed.
The utility model advantage and good effect are:
The plant condenser that the utility model the provides cooling of the work water cooler of water-ring vacuum pump cooling system
Water adopts double water source to design.Wherein, non-summer condition cooling water source is former design water source;Summer condition cooling water source is newly to surge
Source, using the underground water for cooling tower raw make up water as the cooling medium of water ring pump summer condition working water, not only can effectively solve
The problem that certainly summer condition water ring pump service behaviour deteriorates, and low cost, need not additionally increase operation energy consumption, good economy performance.
