No negative pressure water equipment selection | built water | Hezhou negative pressure water equipment

 No negative overlying water supply equipment | Senior negative pressure water supply equipment | frequency overlying water supply equipment 1, with over voltage, under voltage, overload, short circuit, phase, low-level functions. 2, the adjustment of high precision, and can be reached 0.01MPa, the system pressure was maintained at the set value unchanged. 3, easy to operate, with automatic fault stored, fault display. Pressure can be set directly from the keyboard. 4, the advantages of energy-efficient negative pressure water equipment, such as supporting the use of the pressure tank, the better, saving 20% ??to 50%. 5, double pump timing switching. With a preparation of control. 6, compact, small footprint, easy maintenance. According to its realization negative pressure water equipment features different works can be roughly divided into the following forms: (a) steady flow compensator and vacuum suppressor control mode when the municipal water supply pipe network or user inadequate water supply is greater than the municipal network When the capacity of intelligence without negative pressure water equipment, vacuum suppressors open, air enters the steady flow compensator, so that the original closed compensator into break tank, suppression of negative pressure produced another set level control in the steady flow compensator no negative pressure water equipment procurement, when below the low, the pump stopped working. (B) controlled limiting mode when the municipal water supply pipe network or user inadequate water supply capacity is greater than the municipal pipe network, the pressure sensor feedback signal, take restrictive inverter, so that the pump does not over-water, and when the municipal pipe network When the water supply to meet the requirements, the system returns to normal. (C) the pressure control point mode when the municipal water supply pipe network or user inadequate water supply capacity is greater than when the municipal pipe network, straight from the variable flow constant pressure pump, until the water supply to meet the requirements, the system returns to normal. No negative pressure water equipment selection | built water | Hezhou negative pressure water equipment built by Hunan Water Supply Equipment Co., Ltd. Built in Hunan Water Supply Equipment Co., Ltd. (www.hnzjsb.com) (www.zjgongshui.com) is a leader in Changsha, Hunan, drinking water treatment equipment, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness , and satisfy customer needs. In the construction of the water supply led the staff warmly welcome all inquiries negotiations to create the water built a better future.
