No negative overlying water supply equipment, overlying water supply equipment, water supply built in multi-map

No negative pressure water equipment | frequency without negative pressure water equipment | frequency booster overlying water supply equipment | Water Equipment Co., Ltd built in consultation equipment put into use, the water pipe network steady flow of water into the tank, the tank air from the vacuum eliminator discharge, until the water is full, remove the vacuum automatically turns off. When the water pipe network pressure to meet the water requirements, the system by the valve from the users directly to the water pipe network; when the water pipe network pressure can not meet the water requirements, the system pressure signal from the remote pressure gauge back to the inverter controller, the pump run and the size of water automatically adjust the speed constant pressure water supply based on, if the operation speed of the pump reaches power frequency, start another pump frequency operation. Pump water, if the water pipe network is greater than the pump flow to maintain normal water supply. Water peak, if the water pipe network is less than a small amount of pump flow, steady flow tank water as a supplemental source of water can still be normal water supply, this time, the air from the vacuum eliminator into the steady flow tank, vacuum tank destroyed, ensure the water pipe network does not produce negative pressure water peak after the system has returned to normal supply state. When the water pipe network without water, resulting in steady flow tank levels continue to decline, the level detector will signal back to the inverter controller, the pump automatically shut down to protect the water pump. Small flow of water at night and the water pipe network pressure can not meet the requirements, the surge tank can store and release energy, avoid frequent pump starts. The level of dual-chamber negative pressure water equipment to install? In the construction of water supply equipment to teach you the level of dual-chamber basis of the drawings negative pressure water equipment foundation size should be provided by the manufacturer, its location and the standard should be consistent with the engineering design and TJ231 "on the basis of the size and location of equipment quality requirements." the level of dual-chamber negative pressure water equipment in place after a level leveling, the aspect level should be less than 0.1% after the level of dual-chamber negative pressure water equipment installation leveling, with expansive cement on the basis of secondary grouting. Maintenance 24 . hours after the twin-level piping should confirm the negative pressure water equipment electrical wiring direction of rotation, to ensure consistency with the standard arrow height twin-negative pressure water equipment and operation - before equipment should Barring pump rotor should be no friction, hysteresis phenomenon --500V shake table to detect low voltage electrical insulation, should be more than 0.5M. - instrumentation and control circuit without damage - full pump inlet valve, close the outlet valve, one by one Open the pump discharge valve, until the liquid fills the pump chamber close the valve - the switch in the manual position, no load to move the pump, its operation should be consistent with the standard arrow direction - one by one manually start and stop the pump Check pump operation without negative pressure water equipment anomalies range | Water no negative overlying water supply range 1, for lack of any water pressure applications; 2, the new residential area, apartments, office buildings, office buildings, hotels, restaurants, hospitals and other high-rise buildings domestic water; 3, low water pressure can not meet the fire water; 4, completed the transformation of the pool, you can use non-vacuum equipment and pool shared water supply, further energy saving; 5, water the middle of the village water pumping station; 6, industrial and mining production, domestic water; 7, the original water quality of secondary water supply system can not fulfill occasions; 8, for the high-rise building water supply needs (ie, life, fire, red separate toilet water) applications;
