This topic is the design and construction of a major for application in chemical lab, circulating water device, cycle is verified by experiment device can definitely chemical laboratory by distillation, distillation, vacuum suction filter and other basic operation caused a large number of sudden water in cooling water erosion problem and security problem; And compared with tap water and low temperature cooling liquid circulating pump, low cost, can save a lot of water and electricity
