[0037] A water ring vacuum pump 1 energy-saving device, comprising:

[0038] A water ring vacuum pump 1, having a plurality of;

[0039] A first pipeline 2, one end of which is connected to the outlets of a plurality of water ring vacuum pumps 1;

[0040] The water storage tank 3, the other end of the first pipeline 2 is connected to the water storage tank 3;

[0041] One end of the second pipeline 4 is connected to the inlets of the plurality of water ring vacuum pumps 1 , and the other end is connected to the water storage tank 3 .

[0042] In this embodiment, the traditional water ring vacuum pump 1 will directly discharge a part of the liquid (water) into the external environment during operation, which not only causes a waste of water resources, but also may cause certain pollution to the environment. The energy-saving device connects the outlets of several water ring vacuum pumps 1 with the water storage tank 3 through the first pipeline 2, so that the discharged liquid can be collected into the water storage tank 3 again, and supplied to the water ring vacuum pump 1 again through the second pipeline 4, thereby realizing the recycling of water resources and significantly improving the efficiency of water resource use. Due to the recycling of water resources, the energy-saving device significantly reduces the demand for fresh water of the water ring vacuum pump 1 during operation and reduces the cost of water use. At the same time, due to the reduction of wastewater discharge, the cost of treating wastewater is also reduced. The energy-saving device can effectively cool and replenish the liquid (water) consumed in the pump by continuously supplying liquid (water) to the water ring vacuum pump 1, thereby maintaining the stability and cooling effect of the working liquid ring in the pump. This helps to improve the working efficiency and stability of the water ring vacuum pump 1 and extend its service life.
