Abstract
The invention discloses a double-source combined water supply device. The double-source combined water supply device is composed of a water supply unit A and a water supply unit B and supplies water to users in a combined mode through the water supply unit A and the water supply unit B. The water supply unit A and the water supply unit B respectively comprises a water supply pump unit with frequency converter control, a control unit of the water supply pump unit, a water tank, an electric valve, a detecting instrument and a pressure water source pipe, wherein the water tank and the pressure water source pipe are mounted in parallel; the water tank serves as the water reservoir for the pressure water source pipe, the outlet of the water tank is provided with the electric valve, and the water tank is connected with the pressure water source pipe through the electric valve; the pressure water source pipe, which is disposed in front of the part where the electric valve and the pressure water source pipe are connected, is provided with the detecting instrument. The double-source combined water supply device has the advantage that the water supply unit A and the water supply unit B supply water to the users in the combined mode and can be automatically switched to each other, so that water supply security can be greatly enhanced. The double-source combined water supply device is particularly applicable to a system with two or more pressure water source pipelines supplying water simultaneously.
Description
Technical field
The present invention relates to pressurization hydrotechny field, specifically a kind of double water source co-supplying device.
Background technology
At present, the many employings of supply equipment single cover pump group of prior art or cistern water supply, its reliability of water supply is poor, easily causes because of equipment fault phenomenon of cutting off the water, and has influence on normal water supply.
Summary of the invention
The object of the present invention is to provide the double water source co-supplying device that a kind of water supply security is good, reliability is high.
The technical solution adopted for the present invention to solve the technical problems is: double water source co-supplying device is made up of water supply unit A and water supply B of Unit, and combined by water supply unit A and water supply B of Unit and supply water to user, water supply unit A and water supply B of Unit comprise supply-water pump group and the control unit thereof of band Frequency Converter Control respectively, water tank, motor operated valve, instrumentation and pressure water source capsule road composition, and water tank and pressure water source capsule road are installed in parallel, water tank is as the amount of the reserve water in pressure water source capsule road, motor operated valve is provided with in the outlet of water tank, be connected with pressure water source capsule road after motor operated valve, and pressure water source capsule road before motor operated valve is connected with pressure water source capsule road is provided with instrumentation.
When instrumentation in water supply unit A detects that connected pressure water source capsule road is anhydrous, first its motor operated valve is opened, automatically switch to the way of supplying water of water tank, the supply-water pump group that the water yield of being laid in by water tank is band Frequency Converter Control and control unit thereof provide water source, after the water yield in water tank is finished, motor operated valve cuts out and is switched to the piped water supply of pressure water source, if now pressure water source capsule road is still anhydrous, then automatically starts water supply B of Unit; Equally, the instrumentation in water supply B of Unit detects that connected pressure water source capsule road is anhydrous and after quantity of water in water tank is finished, then automatically switches to water supply unit A and supply water.After the water yield when water supply unit A and water supply B of Unit are simultaneously anhydrous and separately in water tank is finished, stop supplying water.The pressure water source capsule road of water supply unit A and water supply B of Unit can connect the pipe network from two different water sources, also can connect the pipe network from same water source.Water supply unit A and water supply B of Unit arbitrary break down can not normal water supply time, then automatically switch to and supplied water by another water supply unit.
The invention has the beneficial effects as follows, the present invention adopts water supply unit A and water supply B of Unit to combine and supplies water to user, and automatically can switch mutually, thus substantially increase water supply security, reliability, be particularly suited for the system simultaneously supplied water by two-way or two-way above pressure water source capsule net.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present invention.
In figure, 1, water supply unit A, 2, water supply B of Unit, 3, the supply-water pump group of band Frequency Converter Control and control unit thereof, 4, water tank, 5, motor operated valve, 6, instrumentation, 7, pressure water source capsule road, 8, user.
Detailed description of the invention
With regard to accompanying drawing 1, following detailed description is done to double water source co-supplying device of the present invention below.
As shown in Figure 1, double water source co-supplying device of the present invention is by water supply unit A(1) and water supply unit B(2) form, and by water supply unit A(1) and water supply unit B(1) combine and supply water to user (8), water supply unit A(1) and water supply unit B(2) comprise the supply-water pump group and control unit (3) thereof of being with Frequency Converter Control respectively, water tank (4), motor operated valve (5), instrumentation (6) and pressure water source capsule road (7) composition, and water tank (4) is installed in parallel with pressure water source capsule road (7), water tank (4) is as the amount of the reserve water in pressure water source capsule road (7), motor operated valve (5) is provided with in the outlet of water tank (4), be connected with pressure water source capsule road (7) after motor operated valve (5), and pressure water source capsule road (7) before motor operated valve (5) is connected with pressure water source capsule road (7) is provided with instrumentation (6).
At water supply unit A(1) in instrumentation (6) when detecting that connected pressure water source capsule road (7) is anhydrous, first its motor operated valve (5) is opened, automatically switch to the way of supplying water of water tank (4), the water yield of being laid in by water tank (4) is be with the supply-water pump group of Frequency Converter Control and control unit (3) thereof to provide water source, after the water yield in water tank (4) is finished, motor operated valve (5) cuts out and is switched to pressure water source capsule road (7) and supplies water, if now pressure water source capsule road (7) are still anhydrous, then automatically start water supply unit B(2); Equally, at water supply unit B(2) in instrumentation (6) detect that connected pressure water source capsule road (7) is anhydrous and after the water yield is finished in water tank (4), then automatically switch to water supply unit A(1) supply water.At water supply unit A(1) and water supply unit B(2) simultaneously anhydrous time and after the water yield separately in water tank (4) is finished, stop supplying water.Water supply unit A(1) and water supply unit B(2) pressure water source capsule road (7) pipe network from two different water sources can be connect, also can connect the pipe network from same water source.Water supply unit A(1) and water supply unit B(2) both arbitrary break down can not normal water supply time, then automatically switch to and supplied water by another water supply unit.
