Zhengzhou no negative pressure water equipment, frequency of water supply equipment Walter true zero-risk agent, is willing to do your sales consultant Walter full intimate water, there you can not think of quality, service and price! Close adviser Tel: 17708450630 张 smiled Address: Changsha High-tech Development Zone, Lu Tin Road on the 8th floor Oak Park 5 Tips: happy day is the day, unhappy day is also the day, why not happy about, make your life more laughter! Zhengzhou no negative frequency of water supply equipment works: no negative frequency of water supply equipment put into use, the water pipe network of water into the water tank, the tank to exclude air from the vacuum eliminator, until the water is full, remove the vacuum automatically turns off. No negative frequency of water supply equipment when the water pipe network pressure to meet the water requirements, the system directly by the bypass valve to the water supply pipe network; when the water pipe network pressure can not meet the water demand, the system pressure signal from the remote pressure gauge back to the inverter controller, the pump is running, and automatically adjust the speed constant pressure water supply according to the size of water, if the running 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, maintain normal water supply system; no negative frequency of water supply equipment when the water peak, if the water pipe network is less than the pump flow, water tank water as a supplemental source of water still normal water supply, this time, into the air from the vacuum to eliminate water tank, the tank vacuum destruction, to ensure that 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 no negative frequency of water supply equipment, resulting in declining water tank level, level detector will signal back to the inverter controller, the pump automatically shut down to protect the water pump, water tank can store and release energy, avoid frequent pump starts. Zhengzhou no negative frequency of water supply equipment is widely used: 1, widely used in high-rise buildings, residential areas, villas and other household water. 2, is widely used in daily water enterprises, hotels, office buildings, department stores, large sauna, hospitals, schools, sports centers, golf courses, airports and other places. 3, is widely used in the production of water in manufacturing, washing apparatus, food industry, factories, industrial and mining. 4, Others: Reconstruction Zhengzhou electric properties are widely used in the old pond water and other forms of non-negative frequency of water supply equipment: 1. The "no negative pressure water equipment," electronic control system with automatic and manual capabilities, and with the fire control center or fire pump networking. 2, two regulated pumps with a preparation, work in rotation automatically switches alternately run. 3, so that the fire pipe network usually at high pressure and maintain a certain amount of water storage tank, due to leakage and other reasons, the system pressure drops to Ps1 when the 1st pump starts automatically when the pressure rises to Ps2 pump stops, the next pressure and under time pressure has dropped to Ps1, the pump automatically starts on the 2nd, and so alternately run, the system pressure is always maintained between Ps1 and Ps2. 4, a quantity of a fire occurs, the system pressure drop from Ps1 to Ps2 output enable signal when the main fire pump light and sound alarm, when the main fire pump start anti-back off pump regulator control signal power, followed by the manual recovery control functions. 5, the electronic control system ad hoc state of repair, which is running as the first pump fault occurs can be easily transferred to the 2nd pump, if the 2nd pump failure, it can be converted into the 1st pump so that a pump in maintenance of the "no negative pressure water equipment," still running. 6, the electronic control box size, electrical control principle and main components of the composition in the Company's electrical automatic control manual reports. Zhengzhou, the service is no negative pressure conversion water supply equipment - heartwarming 1, where to buy our water supply equipment customers, if demand our company will provide the technical staff - doors free installation and technical training; in water supply equipment to reach the customer site 3 days to complete installation. 2, Division I for the sale of water supply equipment for a period of 12 months warranty. The warranty period, the company free treatment of non-human factors and the quality of the equipment itself belongs to occur under normal conditions of use. 3, Division I for the sale of products to provide maintenance services for life. Ensure long-term spare parts supply equipment at preferential prices to ensure supply for at least 10 years. 4, the user equipment failure in the operation, issued in the user maintenance - repair notice after our confirmation, within two hours to give reply by fax or telephone; For on-site service, arrived at the scene within 24 hours in Hunan Province, the province 72 hours within the scene. 5, to provide customers with the non-confidential information required, upon receipt of (potential) customers non-fault information, to give a reply within one working day (8 hours).
