Due to excessive product model, specific price for inquiry small European Contact: 15974143465 Online QQ: 1922601218 I. Introduction water supply equipment without negative pressure water equipment is to computer technology, inverter technology and motor control technology combined with the new water supply equipment; replace the high water tank, ideal for water tower; the development and complement to pressure water supply equipment. The equipment consists of a programmable controller, inverter, and motor control circuit consisting of a closed-loop water pump control system, fully meet the water supply pipe network pressure remains constant. Making the entire water supply system remains the best energy-efficient operation. No negative pressure water supply equipment dedicated life, living Fire dual water supply, frequency constant pressure water systems. Second, the application of a constant pressure water supply equipment, domestic water supply. 2, industrial water, process water constant pressure of special requirements. 3, fire water rise buildings, living quarters, military facilities. 4, the transformation of the old water supply system (air, water towers, water tanks) of. 5, frequency constant pressure water systems. Third, the main features of a water supply equipment, mining with computer control, automatic operation, management is simple, easy to use and reliable. 2, compact, small footprint, low investment, easy to install, easy centralized management. 3, fully functional, realize various functions required by the user panel. 4, according to the required pressure, according to changes in water pump to adjust the motor speed, so that constant pressure water supply equipment, to achieve efficient energy-saving purposes. 5, for more Taipower pump can reliably achieve a soft start, greatly extending the life of the equipment. 6, according to changes in the flow of auto-complete for more than one pump cycle soft-start operation, the whole process stops. 7, with a small pressure tank unit, sent by the remote pressure gauge is fed to the controller, so that the device in a small flow or zero flow may stop further reduce energy consumption and prolong the life of the equipment. 8, complete protection: undervoltage protection, over voltage protection, overload protection, short circuit protection, stall prevention. 9, the working pump and standby pump cyclical operation, automatic inspection and manual inspection function.
