Abstract
The utility model provides a device for eliminating measuring pump pulse ripple is applied to the fluid transportation field, and is undulant for existing in the use of solution flow pump for the higher problem of use cost and designing. The utility model discloses the scheme of taking does: a device for eliminating measuring pump pulse ripple, includes the pipeline of a conveyance fluid, sets gradually filter, measuring pump, buffer tank, flowmeter and attenuator on the pipeline, and another pipeline is drawn forth for the device entry to filter one end on the pipeline between flowmeter and the attenuator, the higher authority set gradually solenoid valve and back pressure valve, and back pressure valve one end is the device export. The elimination is carried fluid medium because of the accuracy and is adopted unfamiliar hydraulic pressure measurement pump to make the pipeline produce great pulsation, has eliminated the damping, has reduced system energy consumption.
Description
Technical field
This utility model is applied to field of fluid, more particularly, to a kind of dress for eliminating dosing pump pulse ripple
Put.
Background technology
Dosing pump be a kind of can meet various strict technological process needs, flow can in the range of 0-100% no
Level is adjusted, for conveying a kind of special displacement pump of liquid (particularly corrosive liquids).Dosing pump is also referred to as dosing pump or proportioning pump,
Dosing pump belongs to reciprocating displacement pump, for accurate measurement, usually requires that the steady state accuracy of dosing pump is less than ± 1%.
With modernization industry towards automation mechanized operation, this situation of far distance automatic controlling continuous development, the matching of dosing pump
By force, widely advantage particularly looms large to adapt to medium (liquid).
Dosing pump belongs to displacement pump, can produce flowed fluctuation in use, and this is to be caused by the structure of dosing pump
, but flowed fluctuation can cause conveying to there is error, not precisely, especially consume excessive power, cause production cost
Improve.
Utility model content
For the problems referred to above, this utility model provides a kind of device for eliminating dosing pump pulse ripple, for solving stream
There is fluctuation so that use cost is higher in amount pump in using.
For solving the above problems, scheme of the present utility model is：A kind of device for eliminating dosing pump pulse ripple, bag
Include the pipeline of a conveyance fluid, filter, dosing pump, surge tank, effusion meter and antivibrator are set gradually on pipeline, filter
Device one end is device portal, the pipeline between effusion meter and antivibrator is drawn another pipeline, sets gradually electromagnetic valve above
And counterbalance valve, counterbalance valve one end exports for device.
Described surge tank is imported and exported not in same axis, imports and exports the perforate that dislocates some distance.
Described surge tank outlet conduit puts in surge tank one segment distance.
Draw a pipeline at described filter inlet and connect a relief valve, the relief valve other end leads to outside system
Portion.
Advantage of the present utility model is：Remove pulse ripple parts using three roads, remove in advance, remove, consolidating and be completely eliminated three
Road measure, cooperates, and reaches optimum efficiency, and eliminating makes pipeline because of accurate conveyance fluid medium using barrier film hydraulic metering pump
Produce larger pulsation, eliminate damping, reduce system energy consumption.Remove the import and export of component buffers tank medium in advance to first and be spy
Different design, makes first pre- removing play maximum efficiency, eases off the pressure for being subsequently completely eliminated.Using this device, make system pipeline
Specifications and models reduce a class, reduces cost.
Brief description
Fig. 1 is the apparatus structure schematic diagram eliminating dosing pump pulse ripple；
In figure：1. filter, 2. dosing pump, 3. surge tank, 4. effusion meter, 5. antivibrator, 6. electromagnetic valve, 7. counterbalance valve,
8. relief valve.
Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is used for this utility model is described, but is not limited to scope of the present utility model.
As shown in figure 1, a kind of device for eliminating dosing pump pulse ripple, by filter 1, dosing pump 2, surge tank 3,
Effusion meter 4 and antivibrator 5 are successively set on same pipeline, and filter 1 one end is the entrance of whole device, and antivibrator 5 is
The end of this pipeline, is connected another pipeline between effusion meter 4 and antivibrator 5, and pipeline sets gradually electromagnetic valve 6 and the back of the body
Pressure valve 7, counterbalance valve 7 one end is the outlet of whole device.Fluid sequentially passes through filter 1, dosing pump 2, delays after flowing into this device
Rush tank 3 and effusion meter 4, and eliminate after fluctuation again through electromagnetic valve 6 and counterbalance valve 7 bleeder through antivibrator 5.Enter in device
Pipeline at mouthful connects a relief valve 8, relief valve 8 other end and device ft connection.
This device relies on surge tank 3, diaphragm type pulse damper 5 and counterbalance valve 7 to eliminate dosing pump 2 pulse ripple, for essence
Really the dosing pump 2 of metering is created good working environment and is improved the service behaviour of pump.In advance except surge tank 3 is installed on dosing pump 2
Outlet, surge tank 3 is imported and exported and is computed the dislocation perforate that keeps at a certain distance away, and exports and extend into certain position, makes liquid
Fully buffer in surge tank 3, eliminate liquid pulse fluctuation for the first order.Diaphragm type pulse damper 5 is installed on dosing pump 2
Surge tank 3 top at exit normal pipeline, absorbs the peak value of pulse between surge tank 3 and counterbalance valve 7 with all strength.Counterbalance valve 7 is installed
At outlet conduit, through and above-mentioned part cooperation, so that the pressure of pipeline is at utmost eliminated, stabilisation systemss output pressure it is ensured that
The stability of metering POF.
