Bozhou water supply equipment Water Equipment Co. Walter Merchants national agency, secondary water supply equipment sailing toward Fairview field Hotline: 0731-82244977 17708450630 smiled Address: High-tech Development Zone, Changsha foot Oak Park Road on the 8th day 5 a floor "to improve the quality of drinking water, protection of water quality and safety," is related to people's health and life safety event. Looking secondary water reform China's urban water supply equipment and technology to be strengthened. Constant pressure water supply equipment is a new energy-efficient water supply equipment, which in the pipe network pressure (or user of water flow) to set the parameters by computer control the output frequency to automatically adjust the pump motor speed to achieve the pipe network closed-loop pressure regulator (PID), the water supply system automatic constant steady pressure to the set value: that the water increases, the frequency increases, the pump speed to accelerate, the amount of water corresponding increase; when the water was reduced, the frequency decreases, slowing pump speed, water quantity is reduced accordingly, thus ensuring efficient users of water pressure and water requirements, while achieving improved water quality and water efficiency purposes, "how much water, how much water is available"; adoption The device does not need to build high water tank, water towers, water quality and no secondary pollution, is an ideal modern construction of water supply facilities. Water supply equipment operating principle: Tap into the conditioning tank, the tank's air discharged from the vacuum to eliminate, to be filled with water, remove the vacuum automatically turns off. When the water to meet the water pressure and water requirements, through the bypass valve direct water supply pipe network; when the pressure of the water pipe network can not meet the water requirements, the system pressure sensor (or pressure controller, electric contact pressure gauge ) gives the signal to start the pump from the pump to run. When the water pump, 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 is less than the pump flow, adjust the tank's water supply as a supplementary source of water still, at this time, by vacuum to eliminate air into the conditioning tank, eliminating the negative pressure water pipe network, water peak period, the system returns to normal state. If the water supply shortage or disruption of water supply pipe network which led to declining water level regulator tank, liquid level controller gives the pump stop signal in order to protect the water pump. At night and a small flow of water through a small expansion tank water pump to prevent frequent start. Water supply equipment Applications: Irrigation: such as parks, farms, orchards, farms and other manufacturing industries: such as manufacturing, washing equipment, food industry, domestic water facility residents: as high-rise buildings, residential areas, villas and other public places: such as hospitals , schools, golf courses, airports commercial buildings: such as hotels, office buildings, shopping malls, large sauna and other water supply equipment Features: 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, 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. Frequency of water supply equipment Description: frequency of water supply equipment to introduce the most advanced inverter technology, the use of imported brand-name converter, programmable logic controller for single or multiple water pump speed control and regulate the number of units to achieve constant pressure variable water supply The closed-loop regulation, so that the water supply system to achieve the most rational and economical operating results, while automated operations. Products desolate tight structure, complete functions, small footprint. Replacing the traditional towers, water tanks and other water equipment, saving engineering investment, shorten the project cycle, to avoid secondary pollution of water. Frequency of water supply equipment Main features: 1, automatic completion of more than one water pump soft start, variable frequency to the entire procedure and stop frequency operation. 2, according to changes in water, into a multi-pump start and stop. 3, LED pressure setpoint and the actual pressure value display. 4, LED frequency indication, frequency exception indicates, the motor failure conditions. 5, protection features: undervoltage protection, overvoltage protection, overload protection, short circuit protection, stall prevention, to prevent burning and other functions.
