Equipment Benefits 1, energy efficient mechanical pressure water supply equipment according to the user's actual water consumption and the use of automatic detection of pressure, adjust the motor speed (power), so that the device is always in efficient working condition. 2, the water pipe network pressure is stable mechanical negative pressure water equipment constituted by a microcomputer automatic closed-loop control, can make the changes in 0.5 seconds, the pressure returned to normal, the pressure regulator setting accuracy of ± 5%. 3, small footprint less investment, short duration installation. Mechanical negative pressure water supply equipment and other old-fashioned equipment to save an area three to 16 times higher than the construction of towers to save to save and invest 15% to 60%. Small, assembly, installation and commissioning, transportation and installation of a short duration. 4, full protection, safe and reliable, easy to operate mechanical negative pressure water equipment machine adopts imported frequency converter itself has an undervoltage, overvoltage, overload, short circuit, overheating, stall prevention, protection, trouble-free use up to 100,000 hours or more. Mechanical negative pressure water equipment distribution control, the use of intelligent control theory, operation convenient and practical, the device status at a glance. Facilitate non-professionals quickly master. 5, the water full of features, high safety factor no negative pressure water supply equipment mechanical partial failure, to enable emergency response capabilities continue to supply. With the municipal water supply network and network operation, and has dual voltage capabilities, that is able to meet the normal life and production of water pressure and flow in the event of fire can be automatically converted to a high pressure and large flow of water, a multi-purpose machine. Product Features 1, need to build reservoirs or roof water tanks, the use of layers of water supply, reducing the equipment initial investment. 2, can take advantage of the municipal pipe network water pressure, poor, make up much of the negative pressure, power can be maintained municipal water supply pipe network water pressure. 3, by the automatic intelligent controller, based on the user's own water and tap water pipe network pressure regulator, the implementation unattended. And the use of man-machine interface (text, number) display, enabling customers to be more intuitive to see the equipment operating conditions. 4, closed operation, the complete elimination of water secondary pollution. 5, with a perfect overload, short circuit, overvoltage, undervoltage, phase, overcurrent, short circuit, water, water and other automatic protection function. In exceptional circumstances capable of signal alarm, self-test and fault diagnosis. 6, only one set of water supply control cabinet, non-negative steady flow tank and pump unit three parts, the installation is very simple and convenient. 7, more than one pump can achieve reliable soft-start grid and pipeline network to avoid shock, and take turns running, greatly extending the life of the pump and motor. Extended equipment life more than three times. 8, the material flow components generally made of stainless steel, can be customized according to different requirements of users of other materials.
