Description
Technical field
The present invention paddles matter automatic detection industry, more particularly to a kind of water fetching device.
Background technology
In automatic water quality monitoring industry, generally require surface water being pumped into monitoring station and carry out water analysis, and monitoring
Stand within one day usually require to water quality carry out repeatedly monitoring analyze, therefore it is required that water fetching device during monitoring in it is daily
Water can be got (from water head site).
At present, it is main to be fetched water using self priming pump or immersible pump from water head site (such as river), and because the current of river
Flow velocity is big, therefore the difficulty of construction of immersible pump is larger, and immersible pump has the risk being flushed away, so as to be easily caused the shakiness of water intaking
It is qualitative.It is far smaller than big and because the self structure of self priming pump is limited, its actual effective absorption distance is smaller (being generally only 6m or so)
The height of water of most river wet seasons and dry season.So if ensureing that self priming pump can get water in the dry season in river, then
Need to be arranged on self priming pump into relatively low position, and be then possible in the wet season by water submerged, cause water intaking to suspend.If protected
Wet season water intaking is demonstrate,proved, and self priming pump is arranged on to higher position, is then possible to take less than water at dry season.Therefore, extract
Water in river, which carries out detection, has larger unstability, is that the monitoring of water quality and analysis cause influence.
