Technical Field
[0001] The utility model relates to the field of water supply devices, in particular to a variable frequency constant pressure water supply device. Background Art
[0002] A residential building refers to a house that is used exclusively for living, including villas, apartments, dormitories for employees and their families, dormitories for employees and dormitories for students, etc. However, it does not include basements in residential buildings that are used for civil air defense and are not inhabited, nor does it include houses with special purposes such as nurseries, wards, sanatoriums, and hotels.

[0034] The working principle of a variable frequency constant pressure water supply device provided by the utility model is as follows:
[0035] Step 1: First, when supplying water to high-rise buildings, start the No. 2 water pump 21, so that the No. 2 water pump 21 can absorb the water flow inside the water storage tank 5 and discharge it to the inside of the pressure tank 13 through the booster pipe 11, thereby achieving a continuous boosting effect inside the pressure tank 13, that is, achieving a continuous boosting effect inside the drain pipe 10, thereby avoiding the problem that the internal pressure of the pressure tank 13 is limited, resulting in insufficient water pressure inside the drain pipe 10 when the internal pressure of the pressure tank 13 continues to decrease, thereby improving the stability of the water pressure during water supply. When adjusting the water pressure inside the drain pipe 10, the pressure transmitter 12 can detect the pressure inside the water pipe 8, and then transmit the pressure signal to the inverter 6. At this time, the inverter 6 can control the opening and closing of the electromagnetic regulating valve 14, thereby achieving the control effect of the water flow rate inside the pressure tank 13, thereby achieving The constant water pressure inside the plurality of drainage pipes 10 is achieved, thereby improving the stability of the water flow rate. When the water flow inside the water storage tank 5 is stored and transported, the adsorption plate 15 can filter and purify the water flow inside the water storage tank 5, thereby avoiding the problem that the water flow inside the water storage tank 5 deteriorates during long-term storage, thereby causing the water flow inside the water delivery pipe 8 to be polluted. When the temperature outside the water storage tank 5 is low, the electric heating rod 17 is started, so that the electric heating rod 17 can heat the water flow inside the water storage tank 5, thereby avoiding the problem that the water flow is difficult to flow when the water flow temperature is too low and freezes, thereby improving the smoothness of the water flow. When the water storage tank 5 is used outside, the heat insulation sleeve 18 can protect the water storage tank 5, thereby avoiding the problem that the water storage tank 5 ruptures when the water flow inside the water storage tank 5 freezes, thereby improving the protection effect of the water storage tank 5.
[0036] Step 2: When delivering and supplying water, start water pump No. 1 7 so that water pump No. 1 7 can discharge the water flow inside the water inlet tank 2 into the water pipe 8, thereby increasing the water pressure inside the water pipe 8, thereby avoiding the problem of too low water pressure and difficulty in delivery when the water supply height is large, thereby increasing the pressure during water supply. When supplying water, the filter net 19 can filter the water flow inside the water inlet tank 2, thereby avoiding the problem of poor water quality caused by impurities inside the water flow accompanying the water flow, thereby improving the cleanliness of the water flow. When delivering water, the soundproof cover 20 can seal water pump No. 1 7. At this time, the contrast generated by water pump No. 1 when working can be blocked by the soundproof cover 20 to the inside, thereby achieving the sound insulation effect of water pump No. 1 7, that is, the noise reduction effect during water supply is improved.
