[summary of the invention]
Task of the present invention has overcome the deficiencies in the prior art, a kind of network pressure-superposition water supply equipment that adopts complex function energy storage surge tank is provided, the supporting air pressure tank of this device just adopts time-division multiplex technology, not only as the municipal water sources surge tank but also as the voltage stabilizing air pressure tank of equipment delivery port.When municipal ductwork pressure was enough, air pressure tank was as the voltage stabilizing air pressure tank of equipment, because the volume of this air pressure tank is bigger, therefore certain volume adjusted was arranged; When municipal ductwork pressure stopped pump working inadequately, air pressure tank can be used as the water source jar of equipment, because this air pressure tank storage is the water source that certain pressure is arranged, equipment is joined pump lift and can be hanged down more than 10 meters than common product.
The present invention adopts following technical proposals: a kind of automatic network pressure-superposition water supply equipment, comprise water pump assembly, air pressure tank, flap valve and connecting line, also comprise control instrument and controller, it is characterized in that water pump assembly supporting two or many water pumps, the import and export pipeline of air pressure tank is connected on the inlet of any water pump in the water pump assembly, and the inlet of water pump is connected with municipal water inlet pipe by flap valve.
Described air pressure tank is diaphragm type air pressure tank or automatic gas compensating type air pressure tank.
Adopt the pipe network Pressure-superposed water supply equipment of the technical program, its beneficial effect is, using one jar more, the structure design that helps equipment, dwindled equipment volume effectively, saved building area, reduced cost, more useful is that surge tank in the common equipment has been made into the energy storage surge tank, so just the pressure water source of storing can be discharged when municipal ductwork pressure is not enough, in order to the deficiency of compensation municipal water supply, owing to this energy storage surge tank reason, design can consider during pressure of supply water the to superpose minimum hydraulic pressure of city planting ductwork, thus equipment is joined pump lift and can be hanged down more than 10 meters than common product.Power of motor can reduce by 1 specification.
[description of drawings]
Fig. 1 is a pipeline connection diagram of the present invention.
Referring to Fig. 1,1 is control instrument, and 2 is flap valve, and 3 is air pressure tank, and 4 is pipeline, and 5 is water pump, and 6 is water pump, and 7 is control instrument, and 8 is user's pipe network, and 9 is controller, and 10 is water inlet manifold, 11 outfall sewers, and 12 is flap valve.
[specific embodiment]
Below in conjunction with the drawings and specific embodiments the present invention is done detailed description.
1. among Fig. 1, supporting two the same specification water pumps 5,6 of water pump assembly, the water inlet manifold 10 of equipment is equipped with control instrument 1, and water inlet manifold one tunnel links to each other through the inlet of flap valve 2 with water pump 6, and the inlet of water pump 64 links to each other with the import and export of air pressure tank 3 simultaneously by the road.Another road of equipment water inlet manifold links to each other with the inlet of water pump 5.Water pump 6 ports of export connect outfall sewer 11, and water pump 5 ports of export are connected with outfall sewer 11 through flap valve 12, and control instrument 7 is housed on the outfall sewer 11.The automatically controlled output of water pump 5,6 and control instrument 7 connects controller 9.The signal that controller 9 is gathered according to control instrument 7 is controlled the operation implementation procedure of equipment, thereby coordinates the operation of a complete set of equipment.
The operation control method of this equipment is as follows: instrument 1 detects water inlet pressure just often; equipment directly aspirates municipal water sources and supplies water; water pump 5 operations; supply water on the one hand; also be surge tank 3 moisturizing energy storages on the other hand; the equipment of the normal operation of debugging; the hydraulic pressure that keeps user's pipe network 8 between down period by air pressure tank 3; when the air pressure tank energy storage is used consumption; make that equipment started operation automatically when user's pipe network 8 hydraulic pressure were reduced to the low pressure limit of setting, what at first start is water pump 5; this pump directly extracts municipal water sources; at original municipal pressure-based up-conversion speed governing operation, difference what mend how much realize energy-saving run, satisfies constant pressure water supply demand in user's single-pump flow scope; if user's pipe network water increases; water pump 5 can not satisfy the demands, and then starts second water pump, 6 frequency control constant-pressure operations in parallel automatically, because the operation of water pump 6 is direct water source with air pressure tank; and have a certain amount of press water in the air pressure tank 3, therefore city planting ductwork there is certain cushioning effect.If user's pipe network 8 water supply volumes reduce; so that make the water pump operation underfrequency; then can subtract pump automatically; elder generation's diminishing pump 6; water pump 5 is got back to again and is kept constant pressure water supply operation in the single-pump flow scope; because the equipment water supply flow is less during the air pressure tank 3 water-filling superchargings; can not cause excessive suction for air pressure tank 3 water-filling superchargings to municipal water sources; during water pump 5 isolated operations; reduce to very low or be 0 o'clock as user's pipe network 8 water supply volumes, equipment will enter stopping process automatically: water pump 5 quickens operation until the upper pressure limit of being pressurized to setting for air pressure tank 3 water-fillings, water pump 5 autostops then; also be equipment downtime, the air pressure tank 3 start-stop organizational security pressure effects of equipment at this moment.The equipment run duration is during as the minimum swabbing pressure that air pressure tank 3 outlet pipelines 4 place's pressure occurs and allow less than municipal water sources, and equipment is forbidden operation with autostop, to avoid the excessive suction to municipal water sources.And the pressure water source that stores in the air pressure tank can also be kept a small amount of water of user's pipe network.
Air pressure tank 3 can adopt the diaphragm type air pressure tank, because air pressure tank 3 Inlet and outlet waters are the same mouth of pipe, to adopt common capsule formula barrier film air pressure tank comparatively convenient, the main cushioning effect of considering municipal water sources of air pressure tank dischargeable capacity design among the present invention, air pressure tank should have suitable pre-aeration quantity, it is 0.01Mpa-P0 that the pre-aeration quantity of slack tank should make the blowing pressure scope, and P0 is that city planting ductwork allows the minimum hydraulic pressure value that aspirates, and the best pre-the blowing pressure of slack tank is P0.
