The worst thing is that people in life are often hampered by mistake without realizing aspirations, to get rid of those who really can come to understand when obstruction. - Goethe school supply look Changsha Branch far away centuries brand trusted Changsha Branch Water Equipment Co., corporate responsibility century brand of your preference Hezhou dedicated water supply equipment equipment outlined in schools: schools and dedicated water supply equipment is the AC frequency modulation speed technology and computer control technology being applied to the pump automatic control equipment, and combined with the water pump unit mechatronic devices. Private schools and water supply equipment AC variable frequency control cabinet combines advanced computer control frequency conversion technology, advanced computer control technology and advanced PID regulator computer programmable controllers on the current international advanced technology. Private schools and water supply pipe network equipment based on the instantaneous change in pressure and flow parameters, automatically change the number of units and run the pump speed to achieve constant pressure variable water supply loop regulation, so as to improve the company's quality and efficient energy-saving purposes. Secondary water supply equipment principle Changsha, Changsha Yuanke secondary water supply equipment --- Liu sincerely for your service! Intimate adviser: Liu Ye (Ms.) Sales Address: Yuhua District, Italy all the way to No. 66 Asia Business Building 2 Room 1733-1734 market with the world, the quality and life coexist. Hezhou special schools and water supply equipment to extend the life of pumps and motors: for more than one pump can achieve reliable soft-start, make the grid and pipeline avoid impact, and take turns running, greatly extending the life of pumps and motors. Equipment works: 1, the tank water supply system piping and pumps used in the Union as a whole, so that the pump, control cabinet, no negative pressure devices and other equipment into the tank through the separator tank to make equipment and water in the tank isolation. Because the pump is placed (using a dedicated low-noise shield pump) in the tank greatly reduces the noise of the device. 2, pump-inlet connection and no negative pressure device and when there is no negative pressure water equipment. When the pressure is sufficient, no negative pressure device automatically turns on, the municipal water supply pipe network, through direct superposition pressure pump pressurized water supply to the user. When the device detects no negative city municipal pipe network pressure drops, no negative pressure water device starts immediately, no negative pressure device is closed. At this point the user directly from a pressurized pipeline pump pumping up the pressure from the tank to ensure adequate pressure pipeline users. 3, the water tank at the entrance to the intelligent use of a solenoid valve to control water pressure and water level. When the pipeline pressure drop when the pressure pump water from the tank, through the intelligent control, when the tank water level falls below a certain level, and then open the valve from the drainage pipe network, water intake at this time to ensure that a certain pressure, this measure of a You can avoid the peak water, since peaking effect, the second is to avoid the zero-pressure common drain tank, the pressure on the pipe network is a good protection. 4, this equipment in water tanks, pumps, pipes and valves, and other wading materials are used food grade stainless steel material, no secondary pollution of water, while the device is set up Chi circulatory system, every six hours with automatic water tank used in order to ensure that the water quality of fresh water tanks, sanitation and environmental protection. Part of the equipment: 1, modular stainless steel water tank (with pumping stations). 2, intelligent electrical control system. 3, low noise stainless steel multi-stage centrifugal pump (KCDL series). 4, no negative pressure water equipment and anti-backflow device. 5, stainless steel tubing sets. 6, pressure, liquid level signal acquisition, feedback facility. Features: 1, significant economic benefits: Using special schools and water supply equipment, without the construction of towers, no roof water tanks, reducing the construction cycle works, but also solve the high cost of the shortcomings of the project cost, but also to overcome the pressure fluctuations large, the pump starts and frequent deficiencies. 2, rigorous design: special schools and water supply equipment constant pressure pump control system, no matter how the water changes, schools and water supply facilities are dedicated to make the pipe outlet pressure remains constant. 3, reliable operation: in schools and the use of special equipment supply equipment inverter and high-quality domestic water pump, with perfect protection and automatic, manual conversion, the operation is very reliable. Private schools and water supply equipment and good performance, flexible control, anti-interference ability 4. Efficiency: special schools and water supply equipment to adjust the pump speed according to user changes in water, the pump is always working in the high zone, festival electric effect is obvious, than the constant speed pumps can save 35%. 5, operation is simple: special schools and water supply equipment with automatic control, PID regulation, keyboard, man-machine interface (text, numbers) display. The operator simply convert cabinet switch, users can achieve the required conditions, to achieve automatic unattended. 6, the protection function: special schools and water supply equipment with perfect overload, short circuit, overvoltage, undervoltage, phase, overcurrent, short circuit protection features such as automatic water shortage. In exceptional circumstances can signal alarm, self-test and fault diagnosis. 7, small footprint, easy installation: the entire water supply equipment, special schools and only one set of water control cabinet and pump unit, installation is very simple and convenient. 8, to extend the life of pumps and motors: for more than one pump can achieve reliable soft-start, make the grid and pipeline avoid impact, and take turns running, greatly extending the life of pumps and motors. If you have any questions about product knowledge. You can call us, or contact customer service online, we will try our best to provide you with the best quality service and love are the wings of a great ambition behavior. - Goethe
