Embodiment
In conjunction with Fig. 1, a kind of mammoth pump negative pressure pumping water system of the present embodiment, including vacuum pump 11, vacuum tank 21 and 1# water
It pumps 42,1# water pump 42 and water source is connected by drinking-water pipe 41, and drained outward by drainpipe 43.For large-scale water pump, in water pump
When starting starting, need to exclude large quantity of air, and for water pump, generally it is difficult to remove large quantity of air, it is therefore desirable to by vacuum
Tank auxiliary exhaust.
Vacuum tank 21 is evacuated by vacuum pump 11 in the utility model generates negative pressure, the outlet pipe 13 of vacuum pump 11, pumping
Pipeline 14 is connect with vacuum tank 21, for being evacuated to vacuum tank 21, makes its internal generation negative pressure.Also connect on outlet pipe 13
It is connected to vacuum pump hand-operated valve 12, is used for its work of manual control.
In order to make it generate negative pressure water suction the exhaust of drinking-water pipe 41, which leads to the first branch 31 and second
Road 33, the first branch 31 are connect with drinking-water pipe 41, and control the first branch 31 by solenoid valve A valve 32.
Preferably, the junction distance 1# water pump 42 of the first branch 31 and drinking-water pipe 41 is 0.3~1.0m, such as it is selected as
0.5m.Suitable distance can satisfy the negative pressure needs that draw water, and will not influence the installation of each section.
Second branch 33 is connect with 1# water pump 42, and is controlled by solenoid valve B valve 34.Specifically, have on 1# water pump 42
Evacuation port, the ponding for being discharged in 1# water pump 42.The utility model connects the evacuation port of second branch 33 and 1# water pump 42
It connects, then can be directly evacuated from the evacuation port and generate negative pressure.
In order to guarantee that vacuum tank 21 effectively works, check-valves 44 is provided on drainpipe 43.Then taken out to drinking-water pipe 41
Airflow reflux is not had when vacuum.
Alternatively, hand-operated valve is respectively arranged in the first branch 31 and second branch 33.The hand-operated valve energy
Enough artificial closure guarantee to carry out repair and replacement to the solenoid valve of two branches under the state of drawing water.
In order to monitor the pressure in vacuum tank 21, which is connected with pressure vacuum ga(u)ge 22, for detecting vacuum tank
21 internal pressures.
In order to not influence work is vacuumized, there are two the settings of the present embodiment intermediate pump 11, and two vacuum pumps 11 are in parallel even
It connects, and is provided with vacuum pump hand-operated valve 12 on the outlet pipe of vacuum pump 11 13.One of vacuum pump 11 works normally, separately
One can be used as it is spare.When vacuum pump 11 is not able to satisfy work requirements within one day, can also two vacuum pumps 11 work at the same time.
If a water pump is only arranged, when it generates failure, normal production work inevitably will affect.If two water
It pumps while being connected into a pipe-line system, equally will affect control work.Alternatively, which is additionally provided with 2#
Water pump 5, the 2# water pump 5 is identical as the pipeline arrangement of 1# water pump 42, and is connected to the same vacuum tank 21.
In addition, it is worth noting that, 1# water pump 42,2# water pump 5, solenoid valve A valve 32, solenoid valve B valve 34 and vacuum pump 11
Deng being connect with control system signal.Each section working condition can be directly controlled by control system.The control system is PLC
Control system, it is of course also possible to use other systems, are not specifically limited.
When work, the water supply and sewage work of the large centrifugal water pump of pipe valve bore 200-700mm can satisfy.As schemed, two
Water pump a preparation and a use, wherein a water pump is in operating status during normal production, and the outlet of water pump and general pipeline have the water of 300kPa
Pressure and certain water flow export, and meet normal production requirement.Due to continuous production need, at regular intervals, need into
Row changes pump operation.
Such as the operation of 2# water pump 5 is after a certain period of time, the normal 300kPa of drinking-water pipe hydraulic pressure, changes pump instruction in PLC system operation,
Vacuum pump 11 is opened, the exhaust valve 23 of vacuum pump 11 is opened, then opens solenoid valve A valve 32 and solenoid valve B valve 34, opens one
Vacuum pump 11 closes vacuum pump, vacuum tank closes exhaust valve 23, closing solenoid valve A valve after vacuum degree reaches -60kPa or so
32 and solenoid valve B valve 34.Be then turned on 1# water pump 42, adjust 42 working frequency of 1# water pump, manifold pressure stablize 300kPa with
On, reduce the motor working frequency of 2# water pump 5, change water supplying pump it is normal after, work is exited in the shutdown of 2# water pump 5, and pump is changed in completion.
Schematically the utility model and embodiments thereof are described above, description is not limiting, attached drawing
Shown in be also one of the embodiments of the present invention, actual structure is not limited to this.So if this field
Those of ordinary skill enlightened by it, without deviating from the purpose of the present invention, not inventively design
Frame mode similar with the technical solution and embodiment, all should belong to the protection range of the utility model.
