Provide water supply of steady flow of net pressure boost without negative pres
From;    Author:Stand originally
2 kinds do not have negative pressure (without suck Cheng) plan of * of brief introduction of plan of water supply of steady flow of pressure boost tubal a network, A its basically control system, negative pressure to detect by personal computer frequency conversion reach compensator of aircrew of processing system, water pump, steady flow, vacuum to restrain implement, all sorts of pipe fitting, valve form. This equipment uses personal computer to control frequency control to realize constant voltage water supply, what through vacuum compensation system and whole sealing structure came true to manage a network with tap water is direct string receive, and overcame the undesirable effect to managing a network. This equipment passes vacuum...
