Product Review: GXWG no negative pressure (no suction) frequency power supply equipment is my company developed a new type of energy-saving innovation supply complete sets of equipment. The device is based on the original development of the seed can be connected directly to the official website of the water and the water pipe network does not produce any negative effects of closed sets of water supply equipment. He can replace the reservoir, to take advantage of the pressure water pipe network directly or indirectly supply water, to avoid secondary energy waste and secondary pollution significant savings in infrastructure investment and shorten the construction period. Scope apply: ● residential areas. High-rise buildings, hotels and restaurants production. Domestic water supply. ● waterworks and water pressure system places. ● saving garden lawn sprinkler. Drip water. ● industrial production constant pressure water supply system (printing and dyeing textile, chemical, beverage, smelting) ● transformation of the original pressure water supply equipment. You can take full advantage of the existing pressure tank. ● high water tank and replacement of the old water tower water supply system. Technical parameters: ● Water capacity: 0-100OOm2 / h ● Control Power: ≤550KW ● Ambient temperature: 0-40 ℃ ● Rated input voltage: AC380V ● Pressure range: 0-2.5MPa ● Pressure regulation accuracy: ≤0.01MPa ● Environment Humidity: ≤90% (electrical parts) ● steady flow accumulator: O 5 ~ 100m3 works specifically stated I GXWG no negative pressure (no suction) frequency power supply equipment products control modes: non-touch screen intelligent operation control intelligent operation control mode and touch screen, users choose touch screen control Please specify in the contract. By controlling the controller board set counter water pressure required by the user, time PC monitor municipal pipe network pressure, when the pressure is below the pressure required by the user, the microcomputer automatic control inverter starts, adjust the pump speed increases until pipe network pressure rises to the pressure required by the user, control the pump well at a constant speed operation for constant pressure water supply. When the water increases the speed increases; when the water is lowered to reduce the speed of time to ensure that users of water pressure constant. The lower the water pressure, the higher the pump speed; the lower water pressure pump speed. When the water pressure is greater than or equal to the desired pressure, the pump is stopped. Equipment during operation take full advantage of the original pressure of the water, but also to ensure that the user is always positive water pressure. Equipment during operation, the pressure always monitor the municipal computer networks and systems, automatic control negative suppressors, steady flow of negative pressure accumulator to suppress the generation of both the full use of the municipal pipe network pressure, fork to ensure that no a negative pressure, not municipal pipe network any adverse impact to ensure water safety. When the municipal pipe network without water or insufficient flow equipment automatically shut down, automatically start after the restoration of water supply. Power outage calls after the system restarts automatically restore water supply. This equipment uses advanced PLC intelligent control system to achieve automatic control can be safely detected; failover to achieve unattended function to save personnel costs. Specific features: ● The water pump, power, voltage, fault detection, alarm and protection. ● Pump failover function ● automatic conversion function, soft-start. ● water pump automatic timing switch function. ● Vacuum suppression. ● Small traffic stop packing function. ● level automatic detection and alarm function. ● unmanned automatic operation abide by function.
