Model of pumps in pass-by series was established for sewage subsystem, and through the numerical simulation, the stability and adjustability of the subsystem were discussed. The principle of loop-independence of low resistance pass-by series pipe with tow-stage pumps was discovered. The technical feasibility of tow-stage sewage heat-pump was also confirmed. This thesis has also given out the main points of tow-stage pumps selecting and the methods of system debugging, as well as offered reference for sewage source heat-pump project design.
