Dynamic station pair self priming pump backwash water intaking pipe-line system.
To solve above-mentioned technical problem, this utility model is using the double self priming pump backwash water intakings of such a water quality automatic Weather Station
Pipe-line system, the system include fetch water main line, the first water intaking bye-pass, flushing line, the second water intaking bye-pass and water intaking
Source capsule road；It is described first water intaking bye-pass, flushing line and second water intaking bye-pass front end respectively with the water intaking main line
Rear end be connected, it is described first water intaking bye-pass, flushing line and second water intaking bye-pass rear end respectively with the water intaking source
The front end of pipeline is connected, and the front end of the water intaking main line is connected with the water inlet end of analytical instrument of water quality, described to take water supply line
Rear end be connected with the intake of surface water, it is described water intaking main line on be provided with cleaning pump, described first fetch water bye-pass
On be sequentially provided with the first self priming pump and first check-valve from front to back, be provided with electrical ball valve on the flushing line, described
Be sequentially provided with the second self priming pump and second check-valve from front to back on second water intaking bye-pass, the cleaning pump, the first self priming pump,
Electrical ball valve, the second self priming pump are electrically connected with programmable logic controller (PLC) PLC respectively.
In this utility model, first, second self priming pump stores full water before activation in pump case body.
After said structure, this utility model has the advantages that：
This utility model passes through punching with the tap water of larger pressure by cleaning pump after analytical instrument of water quality analysis is finished
Wash pipeline and reversely water intaking pipeline is rinsed from analytical instrument of water quality direction to intake direction, wash out and remain in water pipe line
Sediment deposition etc. in river, with the accuracy and representativeness that ensure to draw water next time when sampling.
This utility model controls cleaning pump, the first self priming pump, electrical ball valve and second by programmable logic controller (PLC) PLC
Self-priming pump work, high degree of automation improve work efficiency and quality.
This utility model simple structure, low cost of manufacture are easy to promote the use of.
Description of the drawings
Specific embodiment of the present utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a kind of structural representation of the double self priming pump backwash water intaking pipe-line systems of this utility model water quality automatic Weather Station.
Specific embodiment
A kind of double self priming pump backwash water intaking pipe-line systems of water quality automatic Weather Station shown in Figure 1, the system include water intaking
The water intaking bye-pass 2 of main line 1, first, the water intaking of flushing line 3, second and take water supply line 5 at bye-pass 4；First water intaking
The front end of bye-pass 2, flushing line 3 and the second water intaking bye-pass 4 is connected with the rear end 1b of the water intaking main line 1 respectively, institute
State the rear end of the first water intaking bye-pass 2, flushing line 3 and the second water intaking bye-pass 4 respectively with the front end for taking water supply line 5
5a be connected, it is described water intaking main line 1 front end 1a be connected with the water inlet end of analytical instrument of water quality A, it is described take water supply line 5 after
End 5b is connected with the intake of surface water B, on the water intaking main line 1 is provided with cleaning pump 6, in the described first water intaking bye-pass
It is sequentially provided with the first self priming pump 7 and first check-valve 8 on 2 from front to back, electrical ball valve 9 is provided with the flushing line 3,
The second self priming pump 10 and second check-valve 11 are sequentially provided with from front to back on the second water intaking bye-pass 4, the cleaning pump 6,
First self priming pump 7, electrical ball valve 9, the second self priming pump 10 are electrically connected with programmable logic controller (PLC) PLC respectively.
In this utility model, first, second self priming pump 7,10 stores full water or pump case before activation in pump case body
It is interior itself to have water, even if thus in a self priming pump not used time, two self priming pumps are each filled with water.Opening for self priming pump can so be improved
Efficiency of movement, while water is full of in self-priming pump case, can extend the service life of self priming pump.
This utility model takes double self priming pump double path systems, is controlled by programmable logic controller (PLC) PLC, first,
