Liaocheng frequency of water supply water beyond the limits of the preferred Walter, Walter taste wonderful! Tips: World water, Chinese water, city water, please conserve water -------------- vapid all costs, Ben ------------- Liaocheng your future conversion water supply Features: 1, no negative pressure water system can automatically maintain a constant pressure of 24 hours, and based on the pressure signal automatically start the standby pump, stepless adjustment of pressure good water quality, compared with the traditional water supply and will not cause pipeline rupture and faucet resonance phenomenon. 2, moving smooth and reduce the impact of motor pumps, motors and extend the life of the pump, to avoid the traditional supply of water hammer phenomenon. 3, protection of functional, reliable operation, with undervoltage, overvoltage, overcurrent, overheating protection. 4, the configuration can achieve automatic regular water supply, the full realization of unmanned automatic water supply. Control system with fault alarm and display functions, and can be labor-conversion, emergency water supply. 5, the system according to changes in water users to adjust the pump speed, the pump is always working in the high zone, when the system is zero flow, the unit goes to sleep, the pump is stopped, the flow rate increases after work, saving effect is obvious, compared to the constant speed pumps can save 23% -55%. 6, no roof tank, reducing the cost of the building, but also overcome secondary pollution of water, pressure fluctuations, frequent pump start the construction of towers and one-time investment, long construction period, cost disadvantages. 7, no negative pressure water system control cabinet and only one pump unit, installation is very convenient, less area. 8, using automatic control, the operator simply convert cabinet switch, users can achieve the required conditions, simple operation. Liaocheng frequency of water supply the latest technology: 1 stainless steel runner, sealed with pressure steady flow compensation system, completely cut off from sources of pollution, clean and green. 2. Low investment, no pool, no disinfection. 3. Energy efficient, all make full use of water pipe network pressure, forced triple laminated, low power consumption, low running costs. 4. Small footprint, easy installation. 5. completely buried in the ground, especially for the shortage of land area (special development, special conditions). 6. The automatic control operation, unattended design. 7. The high life, high efficiency, can improve the life of more than three times the pump. 8. The pressure is stable, it will not cause the municipal pipe network pressure fluctuations. 9. superior protection, fault display, alarm. 10. The bypass design, automatic switch, power off the water. 11. Analog screen human-machine dialogue, you can always check, set and adjust operating parameters. Liaocheng core frequency of water supply is in the secondary pressurized water system operation how to prevent the negative pressure generated to eliminate the impact of plant operation on municipal pipe network to achieve safe, reliable, stable at close to the user to ensure that water does not affect the premise, continued water supply. Liaocheng frequency of water supply unique characteristics: 1, high degree of automation, intelligent operation using PID closed-loop regulation, high precision constant pressure, small pressure fluctuations. Overload, short circuit, overcurrent and other automatic protection function, the device is stable, reliable, easy to use and maintain. Automation equipment also has a water supply pump stops, the timing automatically switches pump operation and other functions. 2, smooth control technology if smooth control technology, the system can automatically control the acceleration and deceleration rate based on actual feedback pressure, the pressure the system more stable. Solve the conventional pressure control equipment appear overshoot problems occur when the pump is switched or the case of large water changes, pressure fluctuations relatively large. 3, clear water supply equipment machine interface, easy operation has a double mechanical seal with double mechanical seals meet the negative balance in the premise, even if a mechanical seal fails, another operation immediately to ensure the normal operation of the equipment The situation will not be leaking. 4, according to the system pressure automatic compensation resistance characteristics, when the greater flow resistance of the system becomes. In order to meet the system has enough water at maximum lift to overcome the system resistance, similar products available on the market is basically constant voltage control technology, in setting the system pressure at maximum flow only to set the desired pressure When the small flow of water pressure caused by excess energy waste. Pressure automatic compensation technology can automatically adjust the set pressure of the system water according to changes in the system, and in a small flow of water running in the low pressure, with the increase of water consumption, according to the hydraulic characteristics of the system, gradually increasing the pressure of the system, to maximize energy savings. 5, the reasonableness of the pump selection pump operating point determine the rate and life saving equipment water supply system, we have a wealth of experience in the design and commissioning of pumps and systems, not only consider the single performance of the pump, but also full account of the parallel performance of the pump, the system is more reasonable.
