Abstract
It is in medicament barrel that the utility model, which discloses a kind of pipeline to increase defeated engineering drag reducer automatic filling device,（1）Liquid outlet end be connected with circulation feed pump（2）, the port of export of the circulation feed pump is divided into two-way, passes through material returning valve all the way（3）Return to described medicament barrel（1）, another Lu Yujia agent pump（4）Entrance point connection, described plus agent pump discharge is through flowmeter（5）Connect and outpour pipeline.The utility model passes through the flow for circulating feed and special plus agent, it is to avoid because drag reducer viscosity is big, easily block plus agent pump inlet pipeline phenomenon, make plus agent process be very smooth.Due to being provided with mass flowmenter, the convenient flow for observing drag reducer at any time, it is possible to as feedback signal with oil flow signal combination closed-loop control drag reducer adding amount, makes plus agent precision is higher, prevents the waste of drag reducer to greatest extent.
Description
Technical field
The utility model belongs to special chemical assistant loading technique field, is primarily related to a kind of defeated engineering of pipeline increasing and subtracts
Resist automatic filling device, it can also be used to which other quantifying for high viscosity medicament in addition to drag reducer add.
Background technology
Drag reducer is added in petrochemical industry Oil Transportation Process in Pipeline, it is necessary into pipeline to improve conveying capacity, reduction energy
Consumption.Because drag reducer viscosity is very big, if filling technique and filing provision using common medicament, drag reducer is easy to blocking and set
It is standby, it is impossible to normal filling, influence crude oil pipeline conveying capacity.
The content of the invention
Thus the purpose of this utility model produces, and proposes that a kind of pipeline increases defeated engineering drag reducer automatic filling device.Solution
It the problem of drag reducer of having determined easy occluding device, can not only meet the normal filling of high viscosity drag reducer, and can realize plus dosage
Adjust automatically.
The utility model realizes that above-mentioned purpose is adopted the technical scheme that：A kind of pipeline increases defeated engineering drag reducer automatic filling
Device is to be connected with circulation feed pump at the liquid outlet end of the medicament barrel, and the port of export of the circulation feed pump is divided into two-way, one
Road returns to described medicament barrel by material returning valve, and the entrance point connection of another Lu Yujia agent pump, described adds agent pump discharge through stream
Gauge, which connects, outpours pipeline.
Circulation feed pump described in the utility model is lobed rotor pump.
Described in the utility model plus agent pump is plunger metering pump.
Circulation feed pump plus agent pump described in the utility model are connected with the control circuit in switch board.
Drag reducer supercharging in drag reducer bucket is fed to plus agent pump by the utility model by circulating feed pump, redundance
Drag reducer then returns to drag reducer bucket, into add the drag reducer of agent pump by plus the supercharging of agent pump, by flowmeter and outpour pipeline and add
Enter into crude oil pipeline.Switch board can be added with based on crude feed flow and the drag reducer for adding agent pump outlet flow gauge to measure
Fluence is automatically adjusted plus the method for agent pump motor rotating speed adjusts drag reducer adding amount, realizes that the adding amount of drag reducer follows crude stream
The fluctuation of amount and fluctuate.Due to the flow using circulation feed and special plus agent, it is to avoid easily stifled because drag reducer viscosity is big
The phenomenon of plug plus agent pump inlet pipeline, makes plus agent process is very smooth.Due to being provided with mass flowmenter, convenient observation at any time subtracts
The flow of resist, it is possible to as feedback signal with oil flow signal combination closed-loop control drag reducer adding amount, makes plus agent essence
Du Genggao, prevents the waste of drag reducer to greatest extent.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure：1. medicament barrel, 2. circulation feed pumps, 3. material returning valves, 4. add agent pump, 5. flowmeters, 6. switch boards.
Embodiment
With reference to accompanying drawing, embodiment of the present utility model is provided as follows：
As shown in figure 1, the pipeline described in the present embodiment increases defeated engineering drag reducer automatic filling device mainly by medicament barrel 1,
Circulate feed pump 2, material returning valve 3, plus agent pump 4, flowmeter 5, the grade of switch board 6 composition.The medicament barrel 1 is closed bucket, for containing
Put drag reducer.Its liquid outlet end is connected with circulating the entrance point of feed pump 2.Described circulation feed pump 2 uses cam and turned
Sub- pump, with very strong self-suction and high-lift power, is particularly suitable for use in the conveying of high viscosity liquid.Its port of export is divided into two-way,
Drag reducer bucket 1 is returned to by material returning valve 3 all the way（Because the flow of charging pump is more than the demand for adding agent pump, redundance drag reducer
Drag reducer bucket need to be returned）;The entrance point connection of another Lu Yujia agent pump 4.Described plus agent pump 4 outlet connection flow gauge 5, flow
Meter 5 exports termination and outpours pipeline.Described plus agent pump 4 is high-performance plunger metering pump, can be according to the big ditty for receiving current signal
Its motor speed is saved, to adjust flow, realizes that automatic flow is adjusted.Described circulation feed pump 2 plus agent pump 4 with switch board 6
In the connection of control circuit, it is described control circuit for custom circuit.
Current embodiment require that putting into operation plus during agent, material returning valve 3 is opened, starts the drag reducer in circulation feed pump 2, medicament barrel 1
Sent out through circulating feed pump 2, wherein：A part of drag reducer is returned in medicament barrel 1 by material returning valve 3, another part drag reducer
After adding agent pump 4 to be pressurized, it is injected into through flowmeter 5 in crude oil pipeline.The based on crude flow signal of switch board 6 and flowmeter
5 feedback signals pass through computing, automatically control the motor speed of adjustment plus agent pump 4, to adjust the flow of measuring pump 4, make drag reducer
Adding amount adjusted with the fluctuation of oil flow, it is ensured that the drag reducer moment keep optimum value.
