Description
Technical Field
The utility model relates to an automatic water supply equipment technical field, specific constant voltage frequency conversion water supply equipment that says so.
Background
At present, secondary pressurized water supply equipment is generally adopted in a newly built high-rise water supply system in China, but in old low-rise communities and rural areas in villages and towns, a high-position water storage tank is mostly adopted for supplying water, so that secondary pollution of tap water is easily caused, and if the secondary pressurized water supply equipment is adopted, the defects of high purchase cost and large occupied area are overcome.
Disclosure of Invention
The utility model aims at the above problem, provide a constant voltage frequency conversion water supply equipment with low costs, take up an area of for a short time, energy-conserving effect is obvious.
The purpose of the utility model is realized like this:
the utility model provides a constant voltage frequency conversion water supply equipment, includes water inlet, filter equipment, water shortage protection device, water pump, prevents that flow reversal device, pressure feedback device, voltage regulator device, delivery port, variable frequency control system constitute characterized by: filter equipment (2) is connected in water inlet (1), water shortage protection device (3) is connected in filter equipment (2), water pump (4) is connected in water shortage protection device (3), anti-backflow device (5) is connected in water pump (4), anti-backflow device (5) is connected pressure feedback device (6), pressure feedback device (7) is connected in pressure feedback device (6), delivery port (8) are connected in pressure stabilizing device (7), the signal line of water shortage protection device (3), water pump (4) and pressure feedback device (6) is connected respectively in frequency conversion control system (9).
The utility model discloses simple structure, stable performance's effect has been reached.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1 is the water inlet, 2 is filter equipment, 3 is the water shortage protection device, 4 is the water pump, 5 is the anti-reflux unit, 6 is pressure feedback device, 7 is voltage regulator, 8 is the delivery port, 9 is frequency conversion control system.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples.
As shown in figure 1, a municipal tap water pipe network is connected with a water inlet (1), tap water flows to a water pump (4) through a filtering device (2) and a water shortage protection device (3), a variable frequency control system (9) starts the water pump (4) to convey tap water to users through a water outlet (8), a backflow prevention device (5) is used for preventing water of the user pipe network from flowing back to the municipal tap water pipe network, a pressure stabilizing device (7) is used for preventing the water pressure fluctuation amplitude of the user pipe network from being too large, and a pressure feedback device (6) controls the switching and the frequency of the water pump (4) through the variable frequency control system (9) according to the water consumption of the users to ensure constant-pressure water supply; when municipal tap water is cut off, the water shortage protection device (3) is started, the water pump (4) is closed through the variable frequency control system (9), and normal operation of equipment is protected.
The constant-pressure variable-frequency water supply equipment is low in cost, small in occupied area, simple in structure, stable in performance, and capable of saving resources and preventing secondary pollution of a water source.
