But ambition is the memory of slavery, freshness to the birth, but it is difficult to grow. - Shakespeare Hezhou look Yuanke water supply cheap corporate responsibility, century-old brand, factory outlets, national sales Hezhou frequency control water supply equipment Equipment Overview: At runtime inverter pump motor speed control by speed maintain a constant pressure change when the actual pipeline pressure below the set pressure, the inverter will soft-start cycle sequence corresponding number of units to meet the constant pressure water pump, when the actual pressure is higher than the set pipe water When pressed, the inverter in reverse order of the corresponding pump motor cut off. 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 2 1733-1734 Asia Business Building Room equipment works: equipment before being put into operation, we should first set the working pressure water supply equipment, and other related operating parameters, Hezhou frequency control water supply equipment running, continuous acquisition by the pressure sensor in the water supply pipe network pressure and rate of pressure change signal and converts it into an electrical signal is transmitted to the inverter control system, the control system will be fed back signal and compares the set pressure and operation, if the actual pressure is lower than the set pressure, then issue commands to control the pump run faster, if the actual pressure is higher than the set pressure, the pump control deceleration, when it reaches the set pressure, the pump is maintained at the operating frequency. If the variable-speed pump reaches the rated speed (frequency), after a certain period of time to determine if the pipe pressure is still below the set pressure, the control system will switch to the pump frequency operation, and start the next pump frequency, until the pressure reaches the set pressure of the pipe network; on the contrary, if the system is to reduce water consumption, no negative frequency of water supply equipment, water pumps deceleration command, when reduced to the effective speed of the pump, the pump is running in the first to start the pump stops run, a reduction of the number of units to run the pump until the pipe network pressure constant at the set pressure range. Main pump stopped working, vice pump for constant pressure water supply, to further improve the work efficiency, saving energy. Do a project, a brand tree to pay a group of friends! Sincerely treat every customer! ? Changsha Yuanke Water Equipment Co., national sales, quality assurance! Features water supply equipment: water pressure needed to set, according to the frequency of water pipe network adjust the pump speed, the pump is always operating at high efficiency conditions, compared with the normal frequency control tower Hezhou supply equipment, energy-saving effect up to 20%. 1 small impact on the grid, the protection function eliminates shocks and disturbances on the grid when the pump motor direct start, and equipment control system has a short circuit, overcurrent, overvoltage, overload, undervoltage, overtemperature protection and other functions, greatly improve work efficiency, extend the life of the pump. 2, man-machine interface touch panel operation, flexible and convenient to set parameters. Flexibility to set the frequency limit, acceleration time, deceleration time, for a variety of operating parameters such as pump time, be able to show system uptime, access to a variety of reasons for failure. 3, regular wake-up due to the water supply pipe network equipment is based on how much water to determine the number of units put into operation the pump, so when long-term changes in water within a small range of pumps will make a long-running and badly worn, and Other long-term use pumps cause rust, you can easily solve this problem after setting this function. For multiple pumps with flow, for the same average working hours of each pump shall be provided to change the timing of the pump function. After setting the timing for-pump function, when a variable displacement pump continuous working time exceeds a set value, and there is a variable pump is "resting" state, the inverter automatically switches to start "rest" the longest variable pump, and stop the original variable displacement pump, in order to ensure equality of each pump running time, to extend the life of the pump. Time can be set arbitrarily change the pump. Equipment Scope: Widely used in residential areas, domestic water production water hotels and other public buildings, boiler feed water, booster pump station, various types of industrial and mining enterprises, fire water, boiler water constant, pressurized pipelines, water systems, irrigation and so on. Ideals and aspirations of people often directly proportional to his ability. - Johnson
