The advantage of this system: 1, household set up, easy to use, flexible, fully realized household use metering. 2, when a large area of ??the building, while the internal load within the area of ??big occasions, use of the system is very beneficial. 3, enabling simultaneous cooling and heating functions in the building. 4, no separate setting room, managers less submersible sewage pump motor lead special processing. Underwater submersible sewage pump long run, harsh working conditions, coupled with the adverse factors other man, the cable would have been accidentally damaged water pipes leaving the multi-stage pump motors, cables, special vulcanized seal the deal after the elimination of the cable breakage damage to the pump hidden pipeline fire pump, the main principle is: diving outer cable sheath is made of rubber, filler and core of the cable, each cable core and the inner rubber foreskin and composed of multi-strand copper wire cable, when the cable outer prepuce or foreskin after the cable damaged pump, the water will follow the gap dielectric cables, such as the inner core and the outer foreskin gap or cable inner core of copper wire into the motor cavity between the submersible sewage pump, thereby burning motor, for my company After the above phenomenon, the single-core cable peeled tin after implantation of rubber processing, rubber and then implanted in the last single-core cable and then the rubber ring seal, the use of vulcanized rubber watertight cable, the motor can dive 20 meters and work, virtually eliminating water from entering the motor pathways pipeline multi-stage pump | Xi'an pump | West by West Baoquan Baoquan water.
