Urumqi no negative pressure water equipment

Secondary water supply equipment Scope 1. apply to any water pressure pressurized water shortage areas. 2. The new residential or office buildings and other domestic use. 3. The lower water pressure can not meet the fire water. The transformation of the original pressure water supply equipment. 5. You must build the pool, you can use non-vacuum equipment and pool shared water supply, further energy saving. 6. waterworks among large water booster pump station. 7. industrial and mining production, domestic water and so on. 8. A variety of circulating water system. 9. especially adapted to the water quality of the water supply particularly demanding applications. The use of a secondary water supply equipment installation, the equipment installation should choose a well-ventilated, low dust, not wet the site, environmental humidity -10 ℃ -40 ℃. Should be fortified in the outdoor rain, lightning and other facilities. 2. To facilitate the equipment around the installation, maintenance, equipment, space should be left 70cm, manholes should be retained 1.5m space, surrounded by floor drains should be located. 3. After selecting the venue, properly handle the foundation, with concrete pouring or masonry tank bearing seat. After the base is fully cured, then lifting the tank and put stability, followed by installation accessories, power. 4, before the test, you should turn off the water supply valves, check valves of the seal, does not allow leakage phenomenon, after driving, you should pay attention to the steering pump. When the pressure gauge pointer to the upper limit, the pump automatically stops. Open the water supply valve to the normal water supply, for regular water supply, you can pull the selector switch to the manual position. 5, the device should always check the pump unit. Centrifugal pumps and check valves found leaking, tighten the flange bolts should be timely replacement of asbestos or root, check the pump can not loose foot bolts to prevent damage to the machine. 6, electrical automatic control system, should be waterproof, dustproof, always check the wiring insulation, connecting bolts are loose and the fuse is good and so on. External pressure gauge is best to use a transparent material wrapped to prevent damage. 7. paint off the tank if found, should be promptly painted maintenance to prolong life. Secondary water supply equipment and technology innovation a secondary water supply equipment is the tank water pipe water supply system and water pumps used together as one, so that the pump, control cabinet, no negative pressure devices and other equipment into the tank by tank compartment board so that 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, the secondary water supply equipment 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, secondary water supply equipment tank at the entrance with a solenoid valve to control intelligent 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, secondary water supply 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 automatically tank water use, to ensure that the quality of fresh water tanks, sanitation and environmental protection. Note a secondary water supply equipment, control cabinet should be installed in a clean, dry, no dripping, non-corrosive, non-conductive dust occasions. 2, the power line phase five-wire system, voltage requirements: 380V ± 10%, into the cabinet should normally be under way into the wire, the zero line, the pressure at ground zero line respectively insulated terminals, ground copper rafts . Require solid and reliable connection. 3, threading pipe should be at the pre-ground, according to the manufacturer or threading diagram embedded design units, steel must be by drawing up pre-ground and wire sets and wear strip lines. 4, impurity debris inside water pipes and equipment must be clean before docking device filled with water behind the quasi-commissioning, commissioning the pump can not load, otherwise it will cause damage to the pump. 5, using temporary power debugging. Site to hit the ground electrode. Take a good ground, after replacing the formal power to ensure the correct direction of rotation of the pump.
