Detailed Product Description: | Qiandong pipe network overlying water supply equipment, water supply equipment Qiandong pipe network layers Mo teach Sangma sleepy descendants, clouds wealth better than poor, man aiming tranquility, new recycling old mountains and rivers. One, Qiandong pipe network overlying water supply equipment Jane takes AC motor variable frequency drive is the rapid development of high-tech in recent years, this inverter technology is mainly used in variable load of pumps and fans, than with the valve orifice to regulate the flow to save a lot of energy, application of this technology is in line with the country's energy-saving product promotion plans. According to the basic principles of fluid mechanics, when the variable speed pump flow adjustment valve replacement, the energy saving effect is very significant. Because speed is proportional to the flow rate and pump; pressure and speed proportional to the square; three times proportional to shaft power and speed of the party. So when the pump frequency control, energy savings compared with regulating valves, saving 40-50%. According to statistics, most of the time of conventional pumps running at rated load. Especially the water plant and the residential area of ??life to the pump, according to the largest selection of water pump design load, while a large load changes with water 24 hours a day, lower at night the water load. With air conditioning, shower facilities into the home, and further increase the water peaks and troughs of the difference. The pump frequency control, according to changes in water to adjust the pump speed, not only can save a lot of lives ZBH Series Frequency constant pressure water supply equipment to replace the towers, high life and traditional tank pressure water supply equipment, the choice of world-renowned Imported brands of high-performance inverter, using high-end micro-controller automatic control single or multiple pump constant pressure water supply. Second, Qiandong pipe network overlying water supply equipment requirements 1, the device uses the pump rotor disk before hand, there should be no friction, catching phenomenon; 2, with 500V low-voltage detection interpolation table motor insulation, should be 0.5MΩ above; 3, far Biography gauge socket 1,2,3 (yellow, blue, red) Crimp Terminals 1,2,3 respectively. Remote pressure gauge or measure with a multimeter resistance, the resistance value of the maximum of 1 and 2, and another for three, with three small resistance value is 1, and 3 large resistance value is 2. Best detected with a multimeter or else pick the wrong line will burn table; 4, remote pressure gauge should be installed to the user pipe line, after the mains outlet check valve; 5, control instruments and line without damage; 6, frequency cabinet power transmission, the non-first-mover drive parameters; 7, open the pump discharge valve, excluding gas; 8, the system first starts or maintenance, repairs, starting when the inlet valve open and close the outlet valve; check throughout the system if there is diarrhea leak. If diarrhea leakage should be excluded before starting; 9, first check the pump when the pump is turned on automatically, such as reversing the swap any two-phase power line wire line position; then go to manually start each pump, such as Reverse same pump motor swap lines; 10, one by one manually start and stop the pump, check pump operation no abnormal phenomenon; 11, without exception after the device is automatically controlled state. Three. Pipe network overlying water supply equipment benefit analysis: TD type of visual expression without suction force the overlying water supply equipment efficiency advantages, combined with our design and manufacturing conventional secondary pressurized water HG type constant pressure water supply equipment and ZBH-type non- Suction force the overlying water supply equipment, for example, the cost-effectiveness analysis is as follows: pipe network overlying water supply equipment comparative analysis: 1) Initial Investment: TD type of water supply equipment is 80% HG type of water supply equipment; 2) operating costs: TD type of water supply Equipment is 32% HG type of water supply equipment; 3) footprint: TD type of water supply equipment area savings of about 90% over an area of ??HG supply equipment, saving investment in infrastructure and land investments 4) life: TD type of water supply equipment life. longer than the HG. From the above analysis shows, TD type without suction force the overlying water supply equipment compared with conventional water supply equipment, the ability to save a lot of the investment and operating costs, energy conservation, and environmental health, which is very significant economic and social benefits. Fourth, the pipe network overlying water supply equipment Conclusion: TD type without suction force the overlying water supply equipment is a kind of water pressure on the basis of the original re-pressurized technology, which broke the previous only for non-pressure water pressure Mistakes and fluid flow through the state's control to ensure that the device limited pressurized pipe network does not produce pressure. Type in the user front end installation ZBH no suction force the overlying water supply equipment, solve the water pipe network restrictions due to the user's problem can not meet the high terrain of the remote user's needs. ZBH type without suction force the overlying water supply equipment is stable, water pressure fluctuation is small, and does not affect the adjacent pipe network pressure. It can be widely used in pressurized water pipe network directly, with great economic and social benefits. Frequency (constant pressure water supply or transformer): pump unit running speed, better able to adapt to the water supply pipe network water pressure changes and user Qiandong pipe network overlying water supply equipment, Qiandong pipe network overlying water supply equipment, Qiandong pipe network layers are not interested in high-water equipment, non-chi air live hundred. |
