Outline The inverter constant (variable) pressure water-supply equipment is the most widely used water-supply equipment in 21 century. HSZBX series inverter constant (variable) pressure water-supply equipment developed by the company is an intelligent mechatronic devices which adjusts the rotation speed and pump number to achieve constant (variable) pressure water-supply. The core equipment of SZB type inverter speed-adjustment control cabinet adopts the most advanced technology in the current world, such as SPWM, IPM, PLC and fuzzy control, etc. The equipment consists of sensors, PID regulators, inverters, programmable controller, control circuitry, pumps, valves, bases and pipe accessories to form a closed circulation control system. According to the instantaneous changes in pipe flow, pressure and other parameters, the equipment achieves constant (variable) pressure flow of the closed circulation adjustment by auto-changing the rotation speed and number of the water-supply pump, which makes the water-supply system keep the most reasonable and economic running status. Features With stable water-supply pressure, the working pressure could also be set on demand to guarantee the pressure of the poorest position. It can achieve a significant energy-saving effect by auto-adjusting the pump rotation rate and number of the running equipment based on the water consumption (>40%). It performs circulatory soft-start for the pump groups in order to reduce the impact and eliminate water hammer. In accordance with the rules of “First open, first stop; first stop, first open and change pump regularly”, the pumps are used in uniform to further the service life of the device. It can keep the clean water quality from a secondary pollution without high water level tank and tower. In this way it could also reduce the workload of the property management section. The device could always maintain the right operation condition because of the self-checking function. Adopting the programmable control, the fully-functioned device could achieve auto-running and easy operation as well as maintenance. It not only has properties of a compact structure, less occupation and investment, but also a short construction period. It can connect with a variety of communication interfaces. Applicable range When the municipal water-supply network can not meet the needs of regional users; When the available water level of the municipal water-supply network is too low; When the pressure fluctuation of the municipal water-supply network is too large; When cutting off the water supply happens so constantly; When the water pipe caliber of the municipal water-supply network is too small; When the areas cannot be equipped with laminated water-supply equipment,which is judged by the local water-supply department.
