No negative pressure water supply equipment constant pressure water supply: water pipe network of water directly into the conditioning tank, the tank air is discharged from the vacuum eliminator, until the water is full, remove the vacuum automatically turns off. When the water pressure and water to meet the water requirements Yulin no negative pressure water supply equipment company, the device directly through the bypass valve to the water supply pipe network; when the pressure of the water pipe network can not meet the water requirements Yulin is no negative pressure water equipment manufacturers Direct system by the pressure sensor (or pressure controller, electric contact pressure gauge) is given from the pump signal to start the pump running. Pump the water supply, if the water pipe network is greater than the pump flow, the system to maintain normal water supply; water peak, if the water pipe network water is less than the pump flow rate, adjust the tank water as a supplemental source of water still water, this time, eliminate air from the vacuum into the conditioning tank, eliminating the negative pressure water pipe network, water peak period water supply equipment, system back to normal state. If the water pipe network without water caused by declining water level regulator tank, level detector gives the pump stop signal in order to protect the pump controller group. No negative pressure water equipment adjustment tank-type water tank has no pressure regulation, with a steady flow inside plus compensation by the electronic control device Yulin no negative pressure water equipment sales, so adjust the tank water circulating at least twice a day to ensure that water quality change. When the water pressure, the condition of municipal pipe network to meet the requirements of negative pressure water directly from municipal water pipe network; otherwise, the water tank from the regulator. This approach has a certain reserve amount of water available for water supply network unstable region, but due to the presence of tanks and manhole, according to the provisions still regularly cleaned and disinfected (data). Water supply equipment, no negative pressure water supply equipment company Yulin, Hairong environmental protection equipment (certified merchants) are provided by Western Environmental Protection Equipment Co. 安海容. West An Hairong Environmental Protection Equipment Co., Ltd. (www.hairongshebei.cn) (www.hrepe.cn) to provide "water supply equipment, water treatment equipment, spraying equipment, sprayers, water softening equipment." Business, the company has "Fuji , Yaskawa "brands. Focus on drinking water treatment equipment industry in Xi'an has a higher visibility. Welcomes inquiries, contact: Yijing Li.
