Background technology
When carrying out high-building construction, often need configuration constant pressure water supply system to meet site operation demand.At present, the constant pressure water supply system at high-building construction scene adopts GC type horizontal multi-stage centrifugal pump that hydraulic pressure is provided mostly, in the situation that meeting water system constant pressure, pressure pump needs constantly from water tank, to draw water to meet water and the hydraulic pressure of executing expenditure of time, cause water pump water supply time long, power consumption is serious, water pump shortening in application life, and GC type horizontal multi-stage centrifugal pump adopts tradition to cram formula sealing, in use procedure seal fragile, leak serious, flight-line maintenance rate is high.
Utility model content
The purpose of this utility model is, a kind of stable, water pump failure rate is low of supplying water is provided, save power and water can the on-the-spot variable frequency control constant pressure water supply system of high-building construction, to overcome prior art deficiency.
The technical solution of the utility model: the on-the-spot variable frequency control constant pressure water supply system of a kind of high-building construction, comprise water tank, water tank is connected with the water inlet end of vertical fire pump by water inlet pipe, vertical fire pump water side is connected with outlet pipe, diaphragm air pressure tank is connected on outlet pipe by pipeline, between the pipeline being connected with diaphragm air pressure tank at vertical fire pump, be provided with distance-transmission pressure gauge, distance-transmission pressure gauge, frequency-conversion control cabinet, vertical fire pump connect by control line successively;
The water side of described vertical fire pump is all connected with outlet pipe with water inlet pipe respectively by connecting hose with water inlet end;
Described vertical fire pump disposes water-shortage protection device;
Described variable frequency control is provided with time control switch cashier's office in a shop;
The two ends of described distance-transmission pressure gauge are respectively arranged with flap valve and one way valve.
Owing to adopting technique scheme, the beneficial effects of the utility model are: constant pressure water supply system of the present utility model adopts vertical fire pump to be combined with diaphragm air pressure tank, make vertical fire pump in this system, take intermittent start stop mode and provide constant water pressure as water system, therefore, greatly reduce the working strength of vertical fire pump, extended the application life of vertical fire pump, reduce the power consumption of water pump simultaneously, save construction cost.In addition, vertical fire pump in the utility model have discharge pressure high, start the features such as sensitive, can be applicable to the constant pressure water supply at high-building construction scene, and vertical fire pump adopts mechanical seal, good sealing effect, during use, can effectively reduce the leakage rate of water, save water source.

Description of reference numerals: 1-water tank, 2-water intaking valve, 3-connecting hose, 4-flap valve, 5-distance-transmission pressure gauge, 6-control valve, 7-diaphragm air pressure tank, 8-one way valve, the vertical fire pump of 9-, 10-frequency-conversion control cabinet, 11-water inlet pipe, 12-outlet pipe.
The specific embodiment
In order to make the utility model object, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment
Referring to Fig. 1, the on-the-spot variable frequency control constant pressure water supply system of a kind of high-building construction of the present utility model, comprise water tank 1, water tank 1 is connected with the water inlet end of vertical fire pump 9 by water inlet pipe 11, vertical fire pump 9 water sides are connected with outlet pipe 12, diaphragm air pressure tank 7 is connected on outlet pipe 12 by pipeline, between the pipeline being connected with diaphragm air pressure tank 7 at vertical fire pump 9, be provided with distance-transmission pressure gauge 5, distance-transmission pressure gauge 5 passes to frequency-conversion control cabinet 10 by force value, frequency-conversion control cabinet 10 is adjusted the duty of vertical fire pump 9 according to the variation of force value, the hydraulic pressure that guarantees whole water system maintains in setting range.The water side of described vertical fire pump 9 is all connected with outlet pipe 12 with water inlet pipe 11 respectively by connecting hose 3 with water inlet end, and therefore, the vibrations that produce during vertical fire pump 9 work can not be delivered on whole pipeline, guarantee whole pipeline stable connection; Described vertical fire pump 9 disposes water-shortage protection device, vertical fire pump 9 damages of avoiding vertical fire pump 9 to cause because of water tank lacks water idle running.On described frequency-conversion control cabinet 10, be provided with time control switch, therefore, constructor can rationally adjust water supply time according to job site water requirements, and water system is utilized effectively.The two ends of described distance-transmission pressure gauge 5 are respectively arranged with flap valve 4 and one way valve 8, can prevent aqueous reflux, and the force value that assurance distance-transmission pressure gauge 5 is monitored is more accurate.
While adopting the utility model to carry out constant pressure water supply to high-building construction scene, distance-transmission pressure gauge 5 by the discharge pressure value real-time Transmission of outlet pipe 12 to frequency-conversion control cabinet 10, frequency-conversion control cabinet 10 compares analysis by setup pressure value on the force value of acquisition and frequency-conversion control cabinet 10, thereby control the duty of vertical fire pump 9, when the discharge pressure value of outlet pipe 12 is during higher than the default force value of frequency-conversion control cabinet 10, illustrate that construction party is water supply volume is very little during this period of time, frequency-conversion control cabinet 10 enters resting state, vertical fire pump 9 quits work, change by diaphragm air pressure tank 7 pressurizes, the required pressure of pipeline when construction is provided, when required pressure of supply water is less than diaphragm air pressure tank 7 pressurize values and is greater than again the default force value of frequency-conversion control cabinet 10, the rotating speed of the vertical fire pump 9 of frequency-conversion control cabinet 10 control and regulation, assure feed water pressure, realizes simultaneously and reduces energy consumption, when pressure of supply water is less than or equal to the default force value of frequency-conversion control cabinet 10, frequency-conversion control cabinet 10 can normal upright fire pumps 9, make water system normal water supply, thereby realize the constant pressure of water system.
