[0002] Vacuum dry pumps, also known as oil-free dry mechanical vacuum pumps or simply dry pumps, mainly include dry screw vacuum pumps and vortex dry pumps. The characteristics of these pumps are that there is no lubricating oil in their working chambers, so they can handle gases containing a large amount of water vapor and a small amount of dust, and have the advantages of higher ultimate vacuum, lower power consumption, energy saving, and maintenance-free.

Therefore, when using a vacuum pump, it is necessary to pay attention to controlling the temperature of the pump to achieve energy saving. Here we propose a vacuum dry pump that uses the energy of water flow to achieve water cooling. Utility Model Content
