Novel intelligent double source constant pressure water supply equipment
Technical field:
The utility model relates to a kind of supply equipment, particularly a kind of novel intelligent double source constant pressure water supply equipment.
Background technology:
When cities and towns high building height surpasses the tap water supply lift, usually need to set up the secondary pressurized feed pump to building water supply.Because suction water pipe can produce negative pressure during pumping for water pump, the water supply administrative department in most domestic city all forbids the suction water pipe of pressure pump directly is connected with the municipal tap water pipe network, has influence on other users' water with the negative pressure of avoiding drawing water.For this reason, conventional secondary pressurized equipment is equipped with water tank.Tap water is put into first water tank, and the suction water pipe of feed pump links to each other with water tank, extracts the water of water tank for past high building resident family.Can't utilize the overbottom pressure of tap water during such device secondary pressurized, cause energy dissipation.In addition, if adopt non-negative pressure water-supply installation, though the negative pressure that produces in the time of can solving the tap water access, the water tank capacity is little, cost is high, in case the output of tap water less than the pump-out of water pump, this device can only be cut off the water.
Summary of the invention:
For above-mentioned the deficiencies in the prior art, the purpose of this utility model provides a kind of novel intelligent double source constant pressure water supply equipment, the suction water pipe of this equipment is connected to tap water pipe network can not produce negative pressure to tap water pipe network, when tap water supply is normal, can utilize the overbottom pressure pressurization of tap water to supply water, and, but Automatic Extraction storing water in water tank water supply not enough or when cutting off the water when tap water hydraulic.
The purpose of this utility model realizes by the following method: novel intelligent double source constant pressure water supply equipment comprises water inlet pipe 1, water tank 2, suction water pipe 3, water knockout drum 4 water pumps 5, water collector 6 vacuum tanks 7, distance-transmission pressure gauge 8 and intelligence controlling device 9, and described water tank 2 and suction water pipe 3 are connected on the described water inlet pipe 1 separately; Described water tank 2 converges by outlet pipe 11 and suction water pipe 3 and is connected on the water knockout drum 4; Described intelligence controlling device 9 adopts large panel operation interface, double-core, many whistle control systems.
Described water tank 2 outsides are provided with water inlet pipe 10 and outlet pipe 11, and the top is provided with manhole 12, exhaust opening 13, fluid level controller 14, overfall 20, sewage draining exit 21.
The water inlet pipe 10 of described water tank 2 and described water inlet pipe 1 coupling part are provided with electromagnetic valve 15.
Vacuum meter 16, electro connecting pressure gauge 17, vacuum breaker 18, motor operated valve 19 are housed on the described suction water pipe 3.
Described large panel operation interface dimensions is 450mm*650mm.
Simultaneously variable frequency starting operation of two pumps when described double-core control namely moves.
Described many signal controlling are that water pump adopts switch and frequency conversion different control modes.
The beneficial effects of the utility model are: (1) directly is connected in series with city planting ductwork and can cause negative pressure to city planting ductwork; (2) when tap water supply is normal, water pump can utilize the overbottom pressure pressurization of tap water to supply water good energy-conserving effect; (3) not enough when tap water hydraulic or when cutting off the water, the Automatic Extraction storing water in water tank supplies water, assurance user's water demand; (4) intelligent automatic control pump working; (5) adopt large control panel, the equipment operational factor in panel with the digitized forms centralized displaying, clear, be convenient at any time supervisory control system running situation; (6) adopt double-core, many whistle control systems, systematic Water supply pressure is more stable, more reliable performance, and energy-saving effect is more obvious.

Fig. 1 is structural representation of the present utility model.
The specific embodiment:
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
Novel intelligent double source constant pressure water supply equipment is comprised of tap water water inlet pipe 1, water tank 2, suction water pipe 3, water knockout drum 4, water pump 5, water collector 6, vacuum tank 7, distance-transmission pressure gauge 8 and intelligence controlling device 9.Tap water water inlet pipe 1 wherein one the tunnel connects suction water pipe 3, another road water receiving case 2, and then two-way is connected with water knockout drum 4, water pump 5 and gives user side with tap water, intelligence controlling device 9 control water pipe, the water yield of water tank and the work of water pump.
Described water tank 2 outsides are provided with water inlet pipe 10 and outlet pipe 11, and the top is provided with manhole 12, exhaust opening 13, fluid level controller 14, overfall 20, and the bottom is provided with sewage draining exit 21.The water inlet pipe 10 of described water tank 2 and described water inlet pipe 1 coupling part are provided with electromagnetic valve 15, and hand valve, flap valve are installed in described outlet pipe 11 delivery port positions.Vacuum meter 16, electro connecting pressure gauge 17, vacuum breaker 18, motor operated valve 19 are housed on the described suction water pipe 3.Described water tank 2 and suction water pipe 3 are connected on the described water inlet pipe 1 separately.Described water knockout drum 4 connects four road pipelines, wherein one the tunnel directly take over valve, flap valve, hand valve, water collector 6, distance-transmission pressure gauge 8, vacuum tank 7 and send user side, three-way connection (pipe) road serial connection hand valve, connecting hose, water pump 5, connecting hose, flap valve, hand valve, distance-transmission pressure gauge 8, water collector 6, vacuum tank 7 send user side in addition.The large panel operation interface dimensions of described novel intelligent control device is 450mm*650mm.Two pumps while variable frequency starting when the double-core control of described novel intelligent control device namely moves, the two pumps pressure of supply water is peak clipping Pinggu each other, when arbitrary pump or frequency converter break down, does not all affect the normal operation of equipment.Many signal controlling of described novel intelligent control device are that water pump adopts frequency conversion and switch different control modes, the water pump of switch control mainly is in that water supply volume is large, pipeline pressure reduces rapidly or pipeline pressure when continuing to reduce, and starts fast water pump and stablizes pipeline pressure; The part pump adopts variable frequency control, adjusts the operating frequency of pump according to water supply volume.
