Secondary water supply pressure stabilizing equipment and control system thereof

Technical Field

The utility model relates to the technical field of secondary water supply, in particular to secondary water supply pressure stabilizing equipment and a control system thereof.

Background

Old districts mostly use 6-storey old buildings as the main, the water supply mode mainly adopts 'municipal water supply pipeline direct supply + roof water tank', and the roof water tank is used for a long time and in the month, so that a plurality of defects are left. Most roof water tanks are old roof water tanks with reinforced concrete structures, and the inner walls are rough and easy to adhere to dirt; poor sealing can cause secondary pollution of water; the phenomenon of water leakage is frequently caused by lack of maintenance after the use of the building for a long time, and downstairs are heavily lost; at the time of the peak of water consumption, if the roof water tank can not be timely supplemented with water, the roof water tank does not have water, so that residents of more than 4 floors of each single building can not use water, and the cancellation of the use of the roof water tank is an inevitable choice for water supply enterprises in the future.

The roof water tank is eliminated, so that the problem of low water pressure of a high layer is caused, and related measures are also taken by water supply enterprises for the reason, such as newly-built box type booster pump stations. Set up integral type stainless steel water tank between municipal administration pipeline and little outer pipeline of compartment, adopt the water supply mode of "water tank + frequency conversion" to guarantee the safety and the stability of every layer of resident water. However, the arrangement of the pump station tends to occupy the public space of the residential area, the internal layout of the old residential area is compact, the pump station is close to a residential building, the running sound of the pump station is too loud, and the normal life and rest of residents can be influenced. The secondary water supply transformation of the newly-built box type booster pump station needs equipment purchasing, pipeline construction and equipment installation, and the pipeline transformation consumes long time and influences the normal water consumption of residents; in addition, the cost of material equipment and installation cost are considered, and the reconstruction cost of the newly-built box type booster pump station is high.

However, in the process of secondary water supply transformation of old districts, the fact that a lot of old districts only have a few sporadic residential buildings with the height of 8 floors is found, and most of the bottom floors are shops along a street. If the water supply problem of the high-rise building of the scattered residential buildings is solved, the whole district is transformed into the box type booster pump station, which is not preferable from the economical and practical point of view.

At present, aiming at the secondary water supply transformation phenomenon of old communities, equipment which only needs to meet the requirement of high-rise pressure stability of a sporadic residential building and has both cost and performance and a control system thereof are lacked.
