Frequency of water supply equipment manufacturers, technology leadership

Constant pressure water supply equipment schematics and equipment: 1, constant pressure water supply equipment without negative pressure control basic instructions: The system is set to a constant pressure value, if the pipeline pressure is higher than the set pressure value, pressure transmitters The pressure in the pipe back to the constant pressure control cabinet, water directly to the user via the direct supply pipe water supply pipe network users. When the municipal pipe network pressure water pipe network changes or user changes the tube pressure below the set pressure, the pressure in the pipe pressure transmitter back to constant pressure in the control cabinet PlD controller to adjust the frequency controller by PlD constant output frequency, start the pump unit and adjust the pump speed to maintain constant pressure water supply; if the water does not meet the requirements, the control cabinet to control the frequency of multiple start and stop the pump speed and constant pressure pump, so as to achieve a constant pressure variable water supply of claim 2, constant pressure water supply equipment smooth control technology: pressure control system has a smooth control technology. If there is no smooth control technology, equipment is often the case there will be pressure overshoot. In addition and subtraction water pump or large changes occur, the pressure fluctuation is relatively large. After smoothing control technology, the system can automatically control the acceleration and deceleration speed based on actual feedback pressure, the pressure system more stable. 3, constant pressure water supply equipment automatic pressure compensation system based on resistance characteristics, while the larger flow, the greater the resistance of the system. In order to meet system at maximum head water sufficient to overcome the resistance of the system, the general plant. Home only when the system pressure set by the pressure to the desired maximum flow rate set, when the small flow of water pressure caused by excess energy is wasted. [Shangrao / Water Equipment Co., Ltd. Fuzhou through Germany without negative pressure control system has a smooth control technology, can be set to automatically adjust according to changes in system pressure water system, and in a small flow of water running in the low pressure value, as with the amount of water increases, the system in accordance with the hydraulic characteristics, gradually increasing the operating pressure of the system. Thereby maximizing power savings. Rotonde constant pressure water supply equipment remote control system has no negative pressure water equipment with remote monitoring interface can use GPRS, MODEM wired or wireless remote control devices, remote real-time control of each pump status, real-time pressure, constant pressure and frequency systems parameters and fault alarm memory processing. In a voice alarm system with remote devices, when no negative pressure water supply equipment failure downtime, no negative pressure water device automatically dial stored phone numbers, equipment managers to make timely notification service so as not to affect users of water. Text, numbers and graphics organic complexes, which enriched the contents of the system, but also increases the integrity of the system, to facilitate the operator easier and intuitive grasp of proper system operation, greatly improving the reliability of the system. Multiple interfaces on Windows systems left to prepare for the upgrade and the corresponding communication functions if necessary. Voice Alarm System negative pressure water supply equipment to an additional remote voice alarm function, when the device control system failure, the system triggers an alarm dialing system to call the pre-set fixed telephone or mobile phone number, voice notification management personnel need timely maintenance equipment failure, so as not to affect the normal user of water. This control function in order to take up a dial-up telephone line. In medium-sized control system, no negative pressure water supply equipment control is usually soft-start cycle there is a serious flaw in the pump transition from constant pressure to frequency, will produce a fatal electrical and mechanical shock, leading to damage the circuit and network security, the company developed without the impact of conversion technology, you can do without the impact of soft start and soft stop to avoid mechanical and electrical shocks, this technology is very important in the medium-sized device. In large facilities require relatively large fluctuations in water pressure device, you can do way to supply variable transformer, control system based on the number and frequency pump inverter output frequency is constant, the estimated equipment flow, no negative pressure water supply equipment exports to compensate, in order to achieve further energy saving. Our company based on customer needs can monitor wired and wireless monitoring system, there will be no negative pressure water supply equipment operating status transmitted to the monitoring center in real-time monitoring, the monitoring center can also run the device for real-time control. Features Rotonde constant pressure water supply equipment products through Germany A. constant pressure water supply equipment to save General sponsor: do not build pools or tanks, and water pipes connected directly pressurized water, can take advantage of the existing pressure pump parameter correction (such as the original pump head required 60 meters, can now only 30 meters), to reduce operating costs. B. De constant pressure water supply equipment through pure water: Pure water pressure directly after the equipment supplied to the user, the diaphragm vacuum pressure tank with natural non-toxic capsule, sealed connectors, and completely isolated from air, water, no pollution, water quality net is good. Use of computer soft-start frequency constant pressure control, stable water pressure, water pressure is stable. C. De constant pressure water supply equipment through water: fully enclosed structure, eliminate: run, run, drain, drip, ooze, regular cleaning and disinfection of waste water and water pipes direct tandem phenomenon. E. Rotonde constant pressure water supply equipment to save land, saving equipment installation work: do not build pools, no equipment to install water tanks, equipment shipped to the site, the user's water inlet and outlet pipe with constant pressure through Germany Sanmenxia Docking to supply equipment, simple construction, short construction period, small footprint constant pressure water supply equipment 1, saving: optimized energy-saving control software that allows pump to achieve maximum energy saving operation; 2, water: According to the actual use of water pipe network pressure setting, automatic pump out the water, reducing water run, drain phenomenon; 3, reliable operation: implemented by the constant pressure pump soft start, the pump power frequency to the constant pressure of No impact of the switch to prevent the pipe network impact, avoid pipeline pressure gauge, pipe rupture. 4, networking capabilities: full Chinese control configuration software, real-time monitoring of each site, such as motor voltage, current, frequency, pipe network pressure and flow. And can accumulate electricity at each site, cumulative for each pump out the water, while providing various forms of print statements in order to analyze the statistics. 5, flexible control: segmentation water, regular water supply, manually select the work. 6, self-protection function: If a pump fails, take the initiative to the upper machine alarm information, and start the standby pump to maintain water balance. Case-controlled device fails, the user can manually operate the device in order to protect the water supply. Constant pressure water supply equipment operating conditions 1.
