The e-quipment consists of a converter control cabinet, a flow stabilizing tank, the pump unit, meters, valve pipeline unit etc.and issuitable for the water supply system of a tap water pipe network ans required to boost the water pressure and make the flow constant.ZWL5020ZWLGB150ZWLZWL1. No need of water pool, saving both fund and energyZWL micro-computerized non-suction pressure cons- tant-flow water supply equipment is of a notable effect on both fund and energy saving,which, compared to others,can be over 50% for the pool construction cost and 2040%for electricity saving.2.Simple installation and less land usedI t can be equipped with either a horizontal or a ver-tical flow stabilizing tank.the two tanks are of different Features:less space for the horizontal one and less land for the vertical one.the design,manufacture and inspection ofthe flow stabilizing tanks made in this Co.conform with the provisions in GB150steel made pressure containers ,but inside of them no compressed air is stored, unnecessary to be listed in the management scope of pressure containers.3.Extensive purposes and strong suitabilityI t can be used for either living or fire-fighting water supply and equpped with water pumps of any models.when used for fire-fighting water supply, it has to be equipped with the water pump specially for fire-fighting.4.Full functions and high degree of intelligenceI t uses the advanced know-how of convertre control,ZWL MICRO-COMPUTERIZED NON-SUCTION PRESSURE CONSTANT-FLOW WATER SUPPLY EQUIPMENT02ZWLSUS304841ZWL()starting etc,functions and can do signal warn,self-detection and failure judgment and auto matically adjust the water supply flow upon the watre quantity being used.5.Advanced product and reliable qualitythe accessories used with ZWL series equipment have been screened among many manufacturers and therefore hold a reliable quality. The main overflow parts are made of sus304 stainless steel and,eveen the flow stabilizing tank made of common carbon steel,its internal wall is also co-ated with the advanced 841 epoxy polyamide cating for the internal wall of food containers for anticorrosion.the products conform with the provisions in living and drin-king water sanitation supervising & managing method and the key parts inside of the products,relay and miniature pneumatic tank, are those of the world and domestic well-known brands.6.Personalized design,showing a distinctive styleUpon the features of multi-floor buildings,ZWLseries equipment is equipped with a by-pass pipe (omissible for multiple pump units) and aminiature pneumatic tank. When the pressure of the tap water pipe nework can meet with the water used demand, the system supplies water directly through the by-pass pipe and, in the pump switchover proc-ess, the pmeumatic tank acts as constant-pressure.Equipped with pneumatic tank(omitted when not)D DL S SLS W SLW G GDL L LG F SLGwater pump s model:model D-DL, S-SLS,W-SLW, G-GDL, L-LG, F-SLG Number of water pump: expressed with numbersL W Pkind of flow stabilizing tank: L-vertical, W-horizontal(P added means stainless steel material)3(m )3volume of flow stabilizing tank(m )(L/s)Max. water supply flow (L/s)(1/10MPa)water supply pressure (1/10MPa)micro-computerized non-suction pressure constant-flow equipmentfeatures overload, short-circuit,over-voltage,under-voltage,lack--of-phase, overheat and speed-lost protections and soft031.environmental temperature:5-402.RH of air :85%(at 205)3.medium temperature:4-704.voltage of power supply:380V(+5%-10%)Once the equipment is put into use, the water from the tap water pipe network goes into the flow-stabilizing tank,the air inside of the tank is exhausted from the vacuum remover, which will automatically close after being full of water. The system supplies water to the water pipe network directly through the by-pass pipe when the net-works pressure and flow satisfies the demand of use and,while not, the pressure signal of the system is feedback to the converter controller via the remote pressure gauge, the water pump starts running and automatically adjusts the rotating speed upon the water quantity being used to get to constant-pressure water supply . I f the running pump gets to the power frequency rotating speed, then another one starts converter running.when the pump supplies water, the system forms relayed water supply if the supplied water quantity from the tap water pipe network is more than the pumps flow; at the peak use of water,when the saidquantity is lower than the said flow,water supply can be still normal with the water inside of the flow stabilizing tank as a supplementing water source. At this time,air goes into the tank via the vacuum remover to have the vacuum destroyed to make sure of non-suction pressure formed with the network; after the peak use of water, the system resets to the status of relayed water supply. When the net-work stops supply to cause the level inside of the tank continually lowering,the level detector feedbacks the signal to the converter controller and the pump automatically stops to protect the pump unit.154028520534704380V510ZWL MICRO-COMPUTERIZED NON-SUCTION PRESSURE CONSTANT-FLOW WATER SUPPLY EQUIPMENT0405EQUIPMENT FIGURE AND INSTALLING DIMENSIONSZWL MICRO-COMPUTERIZED NON-SUCTION PRESSURE CONSTANT-FLOW WATER SUPPLY EQUIPMENTEQUIPMENT FIGURE AND INSTALLING DIMENSIONS06ZWL MICRO-COMPUTERIZED NON-SUCTION PRESSURE CONSTANT-FLOW WATER SUPPLY EQUIPMENTEQUIPMENT FIGURE AND INSTALLING DIMENSIONS07EQUIPMENT FIGURE AND INSTALLING DIMENSIONS08ZWL MICRO-COMPUTERIZED NON-SUCTION PRESSURE CONSTANT-FLOW WATER SUPPLY EQUIPMENTEQUIPMENT FIGURE AND INSTALLING DIMENSIONS09190 21.
