Description
Technical field
The utility model is related to fluid conveying machine technical fields, and in particular to a kind of suitable for the compacted of on-line monitoring instrument
Dynamic pump.
Background technology
Pollutant load is relatively low in field of environment protection is because of its sample, and the requirement for the sampling amount of reagent is extremely tight
Lattice.It is usually that reagent is driven into reaction utensil as power source using peristaltic pump to test doing reagent sampling.Peristaltic pump
Hose just as being full of fluid with finger pinching one, as finger forward slip tube fluid moves forward.Peristaltic pump is also
This principle is only by idler wheel instead of finger.It is alternately squeezed and is discharged come pump flow by the elastic delivery hose to pump
Body.Just as with two finger pinching hoses, with the movement of finger, managing interior formation negative pressure, liquid flows therewith.
It needs that reagent is added in reaction cup using peristaltic pump on on-line monitoring instrument at present, with rolling inside peristaltic pump
Axis, installed above have a peristaltic pump tube, and when use needs Reagent Tube being installed on pump line, then will be reacted by wriggling pump operation
Reagent, which is added in reaction cup, to be reacted, and to calculate reaction result, therefore the requirement for reagent sample size is tighter
How much lattice, the amount of each reagent sample introduction all directly affect the result of test.Since the peristaltic pump of two axis revolves the sample introduction to turn around
Accuracy of measurement is not high, can thus react reagent and have a huge impact, and after the peristaltic pump time length of two axis of use, just
Can be by pump line crimp, sample size also will produce influence, and it is higher or relatively low to may result in test result in this way.
Utility model content
The purpose of the utility model is to provide a kind of peristaltic pumps suitable for on-line monitoring instrument, solve the above technology
Problem.
Following technical scheme may be used to realize in the technical issues of the utility model is solved：
A kind of peristaltic pump suitable for on-line monitoring instrument, including shell, pump line and runner assembly, the runner assembly are solid
Surely it is set in shell, pump line is overlapped on runner assembly, and one end is pierced by from the reagent inlet on shell, and the other end is from shell
Reagent exit be pierced by, which is characterized in that the runner assembly use two centrosymmetric double shaft tablettings.
The utility model is to solve in peristaltic pump operational process, and feed liquor is unstable at work can not reach water for single shaft
The fields such as matter analysis enter reagent the demand of accuracy of measurement.In particular, making special designing in lower section to the shape of two tablettings
Installing spring and gasket additional makes it ensure the normal work of tabletting using the restoring force of spring in pump work.
Double shaft tablettings lower part is equipped with spring and gasket successively, and the gap between described two gaskets is not more than 1mm.
Double shaft tablettings are divided into the tabletting at tabletting edges at two ends using shaft.
A protrusion is set in the middle part of double shaft tablettings, for supporting pump line to prevent its slump when shaft rotates.
The difference in height of shaft and pump line peak when the height of the protrusion is horizontal no more than tabletting.
The reagent entry port and outlet are all provided with a clamp for fixing pump line position.
The tabletting uses PTFE plastics.
Advantageous effect：The utility model can make online monitoring instruments measurement result more stable, and may make measurement
As a result more accurate, while can also make each single item technology of measurement parameter in on-line monitoring equipment using the peristaltic pump of four axis
Parameter is attained by optimality criterion, while the frequency that peristaltic pump tube is replaced can also be reduced, and saves manpower and materials, on-line instrument prison
The accuracy of survey has not only directly reacted the actual conditions of monitored water quality, and corresponding product is also played to the actual monitoring of water station
Pole acts on, and also plays corresponding supervisory role to the water quality of ambient enviroment.
Description of the drawings
Fig. 1 is the structure chart of the utility model.
Specific implementation mode
In order to make the technical means, creative features, achievement of purpose, and effectiveness of the utility model be easy to understand, under
Face, which combines to be specifically illustrating, is expanded on further the utility model.
Referring to Fig.1, a kind of peristaltic pump suitable for on-line monitoring instrument, including shell 1, tabletting 2 and pump line 3, pump line 3
One end is penetrated from the reagent inlet 4 on shell 1 in pump, and the other end is pierced by shell from the reagent exit 5 on shell 1.
Preferably, clamp is installed for fixing pump line 3 at reagent inlet 4 and reagent exit 5, in case in pump operation, pump line 3 is from pump
Interior abjection.
Tabletting 2 is disposed with spring and gasket using the structure with double rotating shafts with protrusion 6, lower end, between two gaskets
There is the gap of 1mm, two shafts are separately positioned at the edges at two ends of tabletting.Tabletting is 2, and to pump during central point does
The heart is symmetrical, and pump line 3 is overlapped at the shaft of two tablettings.Top pressure when the height of protrusion is horizontal less than tabletting
The shaft of piece and the difference in height 1mm of pump line peak.Preferably, tabletting uses PTFE plastics to prevent pump line leakage from being generated to it
Pollution.
In use, first the pump line at pump reagent inlet is connect with reagent apparatus for placing, the pump line at reagent exit
It is connected with detection device.Peristaltic pump is started, two tablettings start to make reciprocating swing extruding pump line, successively by the reagent in pump line
It is driven into detection device.Because double shafts have preferable cushioning effect, the i.e. adjustable reagent of rotating speed by changing motor into
The speed of liquid is to meet the accuracy requirement of detecting instrument.
The advantages of basic principles and main features and the utility model of the utility model have been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the present utility model is not limited to the above embodiments, described in above embodiments and description
Only illustrate the principles of the present invention, on the premise of not departing from the spirit and scope of the utility model, the utility model is also
It will have various changes and improvements, these various changes and improvements fall within the scope of the claimed invention.The utility model
Claimed range is defined by the appending claims and its equivalent thereof.
