Description

Water supply equipment with multiple frequency converters
Technical Field
The utility model relates to an automatic water supply equipment technical field, specific multi-frequency converter water supply equipment that says so.
Background
At present, secondary pressurization water supply equipment is generally adopted in a newly built high-rise water supply system in China, most of the equipment adopts one frequency converter to control a plurality of water pumps, and when the frequency converter breaks down, the equipment cannot be used, so that the normal life of a user is influenced.
Disclosure of Invention
The utility model aims at the above problem, provide a multi-frequency converter water supply equipment of stable performance.
The purpose of the utility model is realized like this:
the utility model provides a many converters water supply equipment, includes water inlet, water tank, float switch, converter an, water pump a, converter b, water pump b, prevents flow reversal device, control system, pressure feedback device, voltage regulator device, delivery port and constitutes characterized by: water tank (2) is connected in water inlet (1), install float switch (3) in water tank (2) the inside, water pump a (5) and water pump b (6) are connected in water tank (2), converter a (4) is connected in water pump a (5), converter b (7) is connected in water pump b (6), anti-reflux unit (8) is connected in water pump a (5) and water pump b (6), pressure feedback unit (10) is connected in anti-reflux unit (8), voltage regulator (11) is connected in pressure feedback unit (10), delivery port (12) is connected in voltage regulator (11), control system (9) are connected float switch (3) respectively, converter a (4), the signal line of converter b (7) and pressure feedback unit (10).
The utility model discloses simple structure has been reached, the quality is reliable, stable performance's effect.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1 is the water inlet, 2 is the water tank, 3 is the float switch, 4 is converter an, 5 is water pump an, 6 is water pump b, 7 is converter b, 8 is the anti-reflux unit, 9 is control system, 10 is pressure feedback device, 11 is voltage regulator device, 12 is the delivery port.
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 a (5) and a water pump b (6) through a water tank (2), when the water level of the water tank (2) reaches the upper limit of a float switch (3), a control system (9) controls a frequency converter a (4) to start and stop the water pump a (5), or the control system (9) controls a frequency converter b (7) to start and stop the water pump b (6), so that when the frequency converter a (4) or the frequency converter b (7) breaks down, the other water pump can normally work, a backflow preventing device (8) is used for preventing water of a user pipe network from flowing back to a water tank (2), a pressure stabilizing device (11) is used for preventing the water pressure fluctuation amplitude of the user pipe network from being too large, a pressure feedback device (10) controls the on-off and frequency of the water pump a (5) through controlling the frequency converter a (4), the constant-pressure water supply is ensured; when the water level of the water tank (2) reaches the lower limit of the float switch (3), the control system (9) closes the water pump a (5) through the frequency converter a (4), and normal operation of the equipment is protected.
The multi-frequency converter water supply equipment has the advantages of simple structure, reliable quality, stable performance and multiple protection, and ensures the normal water demand of users.
