According to GB50720 relevant provisions of construction engineering construction site fire safety technical Specification 5.3 temporary fire protection water supply system and GB50974 relevant provisions of fire protection water supply and fire hydrant system technical Specification, and according to the factors of easy assembly, convenient movement, turnover, low cost and the like of a construction site, the temporary fire protection water consumption of the construction site can be generally considered to be 54-60 m 3 (can meet the requirement of 1 hour fire-fighting fire duration), and a single barrel with the capacity of 15m is adopted in a construction site 3 4 plastic buckets or single bucket with the capacity of 20m 3 3 plastic buckets as on-site fire-fighting reserve water, in this example, a single bucket with a capacity of 15m is used 3 The 4 plastic buckets can meet the water using requirements of most construction sites.
The utility model discloses in, the play water end of second water supply branch 6 is connected with the fire control water supply pipe network of job site, realizes supplying water to the fire control water supply pipe network of job site.
The utility model discloses in, all install check valve 14 near its side of intaking and the play water side of main pump 8 and auxiliary pump 9 in the second water supply branch 6 to prevent to appear the backward flow because of pressure variation.
The utility model discloses in, the side of intaking of second water supply branch 6, the play water side and the play water side of second water supply pipe 7 all are connected with soft joint 15 of rubber to this effect that can play the damping and fall and make an uproar.
The invention is further described with reference to the following drawings:
during the use, according to the requirement of the fire hydrant bolt mouth of the floor of building to water pressure, set for the required water pressure of second water supply branch 6 play water side through the operating panel of switch board 3, set for the required water pressure of water supply promptly, detect the water pressure of second water supply branch 6 play water side in real time by water pressure transducer 11 to send the real-time water pressure that detects to switch board 3.
As the height of the building changes (gradually increases), the real-time water pressure at the water outlet side of the second water supply branch 6 changes.
Specifically, in the construction stage that the height of the building is not more than 20m, the main pump 8 and the auxiliary pump 9 are not started, and municipal water supply (the water pressure is generally 0.2-0.35 MPa, namely equal to the water column height of 20-35 m) is adopted, so that the water demand of the building with the height of not more than 20m is met, and the energy consumption of the main pump 8 and the auxiliary pump 9 is zero.
At the construction stage that the height of the building is more than 20m, obviously, the water pressure of municipal water supply can not meet the set water pressure, at the moment, the control cabinet 3 controls an auxiliary pump 9 (7.5 KW) to start frequency conversion operation through a frequency converter 12 to carry out pressurization water supply; when assisting pump 9 (7.5 KW) and can't satisfy required water pressure, assist pump 9 (7.5 KW) and convert power frequency operating condition into, slowly start the frequency conversion operation by 3 control main pump 8 (30 KW) of switch board again, reduce the impact to the electric wire netting, reduce the power consumption, it is balanced to maintain water pressure after main pump 8 (30 KW) starts 1min, assist pump 9 (7.5 KW) bring to rest this moment, reduce the live time of assisting pump 9 (7.5 KW), carry out further pressure boost by main pump 8 (30 KW) and supply water, in order to reach required water pressure.
At the stage of great difference in water consumption, namely at night without water consumption or in daytime with very small water consumption (which can be detected by a flow meter installed in the second water supply branch 6), the main pump 8 (30 KW) and the auxiliary pump 9 (7.5 KW) both stop running, and the diaphragm air pressure tank 10 (800L) releases the stored water pressure and supplies water, thereby realizing water replenishing and pressure stabilizing and maintaining the water pressure constant. When the water stored in the diaphragm air pressure tank 10 (800L) is exhausted (which can be detected by a flow meter installed in the second water supply branch 6) and the water pressure is reduced, the control cabinet 3 controls the auxiliary pump 9 (7.5 KW) through the frequency converter 12 to start the frequency conversion operation, so as to perform the pressurized water supply, and the diaphragm air pressure tank 10 (800L) is filled with the water again.
The fire pump room works for 12 hours a day (only the construction stage is operated; the operation is not carried out at night or the operation is required) to calculate:
the main pump 8 (30 KW) works for several minutes to enable the water pressure of the second water supply branch 6 to meet the set requirement (the accumulated operation is calculated according to 1 hour); the auxiliary pump 9 (7.5 KW) is used to maintain the water pressure loss in the second water supply branch 6 for approximately 50% of the day (cumulative operation over 6 hours).
It can be calculated that the energy consumption of the main pump 8 (30 KW) and the auxiliary pump 9 (7.5 KW) during the working hours of the day (12 hours) is: 30KW + 1h +7.5KW + 6h =75KWh, namely the power consumption of one day is 75 degrees.
If the main pump 8 (30 KW) is used for continuous uninterrupted operation to achieve a pressurized water supply, the energy consumption used during the working time of the day (12 hours) is: 30kw × 12h =360kwh, i.e. the electricity consumption of a day is 360 degrees electricity.
The contrast can know, the utility model discloses a municipal administration supplies water and two kinds of water supply methods of fire pump pressure boost water supply, and its power consumption is lower.
Although the present description is described in terms of embodiments, not every embodiment includes only a single embodiment, and such description is for clarity only, and those skilled in the art should be able to integrate the description as a whole, and the embodiments can be appropriately combined to form other embodiments as will be understood by those skilled in the art.
Therefore, the above description is only a preferred embodiment of the present application, and is not intended to limit the scope of the present application; all changes which come within the meaning and range of equivalency of the claims are to be embraced within their scope.
