Address: Long 沙黎托 industry Hanson Park Changsha water, so you have no worries with water! - Box no negative pressure water equipment Profile box is no negative pressure water supply equipment constant pressure water supply standardized products specialized for the perfect integration of human-machine interface control and constant pressure water supply dedicated plc (microcomputer supply control program) from the introduction of foreign The latest design, box no negative pressure water equipment and sophisticated technology combined with Chinese people's water use habits of secondary development. Box no negative pressure water equipment specifically for intelligent pumping station in harsh environments, no, need constant water supply, stable operation and R & D - box function without negative pressure water equipment breakdown box no negative pressure water supply equipment functions are as follows : a highly compact machine, easy to operate, stylish, 4 * 12 large-size LCD, Chinese character display, full instructions, rich and perfect Chinese tips to make general managers pumping station without going through complex training, but also to for each operation with ease, without having a professional engineer its operation. For installation and commissioning personnel, and telephone communication to deal with the general failure to save time, the operation easier. Meanwhile, Mitsui constant pressure water supply controller can be clearly displayed on the Chinese character display its frequency, frequency conversion conditions. 2, box-type negative pressure water equipment parameters entire LCD display, set clear, especially to provide telephone service suppliers to set (user-set), deal with the fault-related issues to facilitate contact as soon as possible. 3 Fault inquiry confirm the latest alarm time, time accurate to the second, work record ten faults, easy to understand the operation of the controller of the system. Detailed fault recording, the system is extremely easy maintenance, engineering staff through information on troubleshooting can clearly understand, quickly take appropriate and timely solutions. 4 has a tank of anhydrous alarm shutdown feature to protect the pump. 5 time and date setting function, convenient recording time various fault conditions occur, convenient query re-examination. 6 fuzzy control theory, automatic optimization parameters, easy operation, fast response, high accuracy, small impact on the pressure in the pipe when the pump is switched. 7 change timing pump function to prevent the same pump running time is too long, and can be accurate to the specific time, scientific dispensing pump operating hours and recorded to improve the life of the pump practical. 8 provides two power-saving modes: sleep and subsidiary small pump function. Sleep function allows the unit at the time interval of a day of zero flow automatically stops the pump, according to the specific needs of start, intermittent water supply, energy-saving effect; subsidiary pump function can solve water-hour emergency use, start saving big pump power . 9 ultra-high pressure water, the pressure signal, explosion pressure, such as automatic detection function automatically stops the pump operation according to the actual situation, to avoid burst pipes and equipment damage, completely stable. 10 offers two supply modes: regular water supply mode (cycle start, frequency increase pump) and peak supply mode (direct start, direct power frequency increase pump), to meet the water conditions in different situations. 11 automatic fault masking function, when a pump problem with the system, the system can automatically skip the pump is running, the pump starts to step down or standby pump, water supply is not running, while the police, to gain time to deal with problems with the pump. 12, the password function (password required parameter setting can be set), security settings, to prevent misuse, so that personnel management. Timed shutdown function can be done at the same time, the cumulative time. The maximum control range of 13 4 large pump, two small pumps (4 + 2). Switch output 14 of all relay outputs can directly drive contactors. 15 All analog and digital opto-isolated, anti-jamming capability, improve electromagnetic compatibility. 16 strong adaptability, can be matched with various domestic and international pressure sensor and converter, widely used range. 17 at the job site equipment, engineers only need to pump the actual practical situation, you can change the parameters of the Mitsui constant pressure water supply controller, such as pressure, time and time change pumps, pressure, etc. can be synchronized, thus ensure the pump is in optimal operating condition. 18 Constant pressure water supply controller with perfect drive protection and motor protection functions, automatic operation without staff on duty. All pumps spare each other, can shield overhaul pump or pumps of various long-term shutdown operations under the new pump combination control. 19 systems can be connected to the host computer (optional). Professional remote monitoring microcomputer platform, real-time monitoring from a computer terminal pump operation, each time pressure, the frequency of the other parameters, the record of the parameters of the system runs automatically saved and can generate EXCEL spreadsheet printing. 20 optional wireless transmission function, up to 2000 m long distance wireless monitoring, intelligent management system is simple and powerful. 21 System pressure setting and start-stop range of adjustable pressure, pressure regulation accuracy of less than + -0.1MPa 22, Mitsui constant pressure water supply controller on the front panel can be arbitrarily hand, any one pump automatically.
