'工作原理及應用范圍'
?工作原理及應用范圍Working principle:The product is detected by a pressure sensor of the pressure, pressure signals through the automatic control circuit identification, amplification, control contactor, so that the pump according to the pressure inside the tank, automatic running and stopping, achieve the purpose of automatic water supply. The work is the process of pump starting, the water through the valve into the tank, so that the tank pressure increases, when the pressure reaches the set pressure limit, automatically shut off the pump automatic pressure controller, the water pump stops running. Due to the pressure of water tank is higher than that of the water supply pipe network pressure, the heart can automatically water buck, when the pressure is reduced to the set pressure limit, automatic control pump start, automatic injection, water tank and so forth, to stop water supply equipment, automatic operation.Scope of application:1, 0. 12m3 J 0. 5m3 small volume, low price of small non tower water supply series, suitable for 3^6 families?2, lm3 ~ 60m3 widely used in towns, factories and mines, institutions, schools, fire, hospitals, troops, buildings, railways, oil and other units; is life, fire, flow water ideal water supply equipment?Installation and maintenance manual for automatic water supply without towerPrinciple, composition, working process and Application 1: Principle: automatic non tower water supply is air pressure water supply;2, Composition: the aut-省略部分-he circuit and the power supply are single-phase 220V and 10A current? The power source first connects to the pressure switch and then connects the pump? When installing, please read the instruction manual carefully and pay attention to ground protection (shown in Figure two)?(Figure two)Three? Pipeline technology: no tower water supply from pressure tank, water pump, check valve, three pass, stop valve, water pipe composition.1, pumps: submersible pumps, self-priming pumps can be used without the tower water supply. In general, single-phase 550W, selects the brand 1 inch caliber impeller submersible pump, self suction pump adopts a single-phase 750W brand, 1 inch diameter jet type can; non brand submersible pump, self suction pump should be selected based on the standard of 750w\1000w; power Hodge pump is not accurate,To be able to provide 3 kg pressure as standard?The above pump selection standards are suitable for plain areas. Because of the differences of topography, physiognomy and underground horizontal level, the selection of pump is also very different? We provide the basic selection calculationmethod for reference.Submersible pump lift: water pump to the tank vertical distance + 30 metersSuction pump suction range: 2 meters below horizontal surface + horizontal surface to tank vertical distanceSelf-priming pump head: 30 35 metersBrand recommendation: Liaoning, Haicheng three fish, Shanghai Huafeng, the new territories, Tai Yuen, Tai Fook and so on
