Overview of the constant frequency of water supply equipment machine adopts imported frequency converter, its own undervoltage, overvoltage, phase, overcurrent, overload, short circuit, overheat, stall prevention, protection functions, trouble-free use of up to 100,000 hours. Equipment distribution control section, the use of intelligent control theory, convenient and practical operation, the device status at a glance, easy to non-professionals quickly master. Production equipment is a constant frequency of water supply protection function, safe and reliable, easy to operate ideal water supply equipment. 2 Installation edit constant frequency of water supply equipment installation should choose a well-ventilated, dust less, not wet the site, environmental humidity -10 ℃ -40 ℃. It should be fortified in the outdoor rain, lightning and other facilities. "Water supply equipment to promote center" made installation site requirements detailed below: a) indoor installation, ambient temperature: 0 ~ 50 ° C (no freezing); b) Relative humidity: ≤ 90% (20 ° C), no condensation; c) Altitude: ≤ 1000m d) equipment operating location should be no conductive or explosive dust, non-corrosive metal or destroy insulation of gas, dust or vapor. e) the quality of water: water quality of life shall comply with GB5749, water quality and production of water shall comply with the process requirements. f) away from heat sources such as electric stove, a place away from vibration or shock. After selecting the venue, properly handle the foundation, with concrete pouring or masonry tank bearing support. After the base is completely cured, and then lifting the tank and put stability, followed by installation accessories, power. 3 Prior to the trial, you should turn off the water supply valves, check valves of the seal, does not allow leakage phenomenon, after opening, the steering pump should be noted. When the pressure gauge pointer to the upper limit, pump automatically stops. Open the water supply valve to the normal water supply, for regular water supply, can pull the selector switch to the manual position. In the course of constant frequency of water supply equipment, the user's water consumption is constantly changing, so there occurs insufficient or excess water supply situation. According to the "water supply equipment Promotion Center" Statistics show that the imbalance between supply water and concentrated reflection on the water pressure, the more water and less water, the pressure is low; less water and more water, the pressure. To maintain a constant water pressure, you can maintain a balance between water supply and water, that the water for a long time too much water, too little water came from water, thus improving the quality of water supply. Equipment maintenance frequency of water supply equipment constant pressure pump unit should be inspected regularly, regular maintenance and add oil. Centrifugal pumps and check valves found leaking, tighten the flange bolts should be timely replacement of asbestos or root, check the pump can not loose foot bolts to prevent damage to the machine. Paint off the tank if found, should be promptly painted maintenance to extend the life. Constant pressure frequency of water supply equipment electrical automatic control system, should be waterproof, dustproof, always check the wiring insulation, connecting bolts are loose and the fuse is good and so on. The best gauge of external transparent wrapping material to prevent damage. Features 1. Water supply pipe network pressure is stable: The device constituted by a microcomputer automatic closed-loop control, can make changes in 0.5 seconds, the pressure returned to normal, the pressure regulation accuracy of ± 5% of the set value. 2. Water-function, high safety factor: the device partial failure, to enable the continued supply emergency functions. The device automatically with the municipal water supply network and network operation, and has dual voltage function, that can meet the normal life and production pressure and flow of water, can be automatically converted to high-pressure flow of water in the event of a fire, can a machine . 3. Energy saving: water pipe network directly connected in series with the docking, but also make full use of existing municipal pipe network pressure, it can reduce energy consumption. According to the "water supply equipment Promotion Center" professional survey data show that energy-saving in general up to 50% to 90%. Recycling water tank inside the tank to avoid water pollution.
