Description
Technical field:
The utility model relates to the used a kind of sampling apparatus in oil field, belongs to the on-line automatic sampler of a kind of crude oil.
Background technology:
Crude oil in China and liquid petroleum product pipeline sampling mostly adopt manual sampling method at present, the defective of manual sampling is: because its sample frequency is little, be subject to influences such as oil transportation operating mode and human factor, cause sample representativeness poor, and the boundary metering dispute that causes thus is increasing.In the oil field sampling link that is absolutely necessary.Crude oil needs often to chemically examine water content in course of conveying, the laboratory personnel needs frequent on-line sampling, crude oil sampling now, once sampling every two hours, chemical examination be the instantaneous water content of crude oil, result of laboratory test is inaccurate.Because the hand sampling complicated operation, blanking time is long, and leakage of oil easily.Both increase laboratory personnel's labour intensity, polluted environment again, the more important thing is that the artificial sample time interval was long, can not accurately reflect original actual water content, and can cause petroleum pipeline two ends result of laboratory test difference.
The utility model content:
Have in the existing crude oil sampling in order to solve that laboratory personnel's labour intensity is big, artificial sample blanking time is long and leakage of oil easily, problem of environment pollution caused, the on-line automatic sampler of the crude oil that the utility model provides, this device has and has reduced laboratory personnel's labour intensity, improved production efficiency, oil-proof, free from environmental pollution, chemical examination accurately, regularly, the advantage of quantitative collection.
The purpose of this utility model is achieved by the following technical solution: this device is by sampling probe, sample receiver, the control display unit, the collateral branch loop, warning device is formed, and sampling probe stretches into crude oil pipeline, and connects the manual ball valve in collateral branch loop, the manual ball valve in collateral branch loop is communicated with crude oil pipeline, and the knockout in collateral branch loop connects sample receiver, control display unit and warning device successively.The collateral branch loop is by manual ball valve, strainer, and circulation pump, blender, knockout, flow meter, manual ball valve connects successively.
The utlity model has following effect: because this device sampling probe stretches in the crude oil pipeline, and connect manual ball valve successively by pipeline, strainer, circulation pump, blender, knockout, flow meter, manual ball valve, and end also stretches in the crude oil pipeline, and knockout connects sample receiver, the control display.Make this device under sealing state, to crude oil sampling, and then to no oil leakage phenomenon, environmentally safe, chemical examination is accurate, and the sample interval is adjustable arbitrarily, the weight of gathering, each acquisition time and time in sampling interval can be regulated by the control display unit, thereby realize timing, quantitative collection, reduced laboratory personnel's labour intensity simultaneously greatly, improved production efficiency.This device is easy and simple to handle, and the automaticity height has been realized the on-line automatic continuous sampling of crude oil.
Description of drawings:
Accompanying drawing 1 is the on-line automatic sampler annexation of crude oil of the present utility model figure;
Accompanying drawing 2 is the on-line automatic sampler of crude oil of the present utility model plane signal schematic diagrams;
In the accompanying drawing: 1-crude oil, 2-sampling probe, 3-manual ball valve, 4-strainer, 5-circulation pump, the 6-blender, 7-knockout, 8-flow meter, 9-manual ball valve, 10-crude oil pipeline, the 11-sample receiver, 12-controls display unit, 13-collateral branch loop, 14-warning device.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further described:
As shown in Figure 1, this device is by sampling probe 2, sample receiver 11, control display unit 12, collateral branch loop 13, warning device 14 is formed, sampling probe 2 stretches into crude oil pipeline 10, and the manual ball valve 3 that connects collateral branch loop 13, the manual ball valve 9 in collateral branch loop 13 is communicated with crude oil pipeline 10, and the knockout 7 in collateral branch loop 13 connects sample receiver 11, control display unit 12 and warning device 14 successively.Collateral branch loop 13 is by manual ball valve 3, strainer 4, and circulation pump 5, blender 6, knockout 7, flow meter 8, manual ball valve 9 connect successively.
Oil cylinder two is a master cylinder shown in Fig. 2 and table 1, is used to drive plunger displacement pump and moves up and down and finish imbibition and discharge opeing function, and two commutations of control oil cylinder are three-position four-way valve, and respective electrical magnet is 2DT and 3DT; Oil cylinder one is an oscillating cylinder, and one commutation of control oil cylinder is two-position four-way valve, and respective electrical magnet is 1DT.Motor is 1.1kw, and voltage is 380V; Oil cylinder two is a master cylinder, is used to drive plunger displacement pump and moves up and down and finish imbibition and discharge opeing function, and two commutations of control oil cylinder are three-position four-way valve, and respective electrical magnet is 2DT and 3DT; Oil cylinder one is an oscillating cylinder, and one commutation of control oil cylinder is two-position four-way valve, and respective electrical magnet is 1DT; Electromagnet voltage is DC24V.
Crude oil flows in the circulation collateral branch loop 13 via sampling probe 2, manual ball valve 3, strainer 4, blender 6, flow meter 8 and manual ball valve 9 compositions under circulation pump 5 effects, and flow velocity and its flow velocity in crude oil pipeline 10 are approaching.After an amount of crude oil behind the blender 6 enters knockout 7, sample receiver 11 is started working, sample is deposited in the sample receiver 11 of adjustable type sealed volume automatically again, in sample receiver 11 and the crude oil pipeline temperature near and do not have a composition loss, the oil flow counting in 8 pairs of collateral branch loops of flow meter.
Show in real time sampling amount and sample time by the control display unit, and while display working condition and type of alarm literal.When abnormal conditions, flow meter signal abnormal conditions appear in trunk line, warning device 14 all can be reported to the police when the equipment firmware self check was broken down, if sampling is transfinited then can autostop and prompting.
During concrete operations, at first open manual ball valve 3 and manual ball valve 9, allow collateral branch's circuit communication, give crude oil on-line automatic sampler energising then, this moment electric motor starting, circulation pump 5 is started working, 2DT gets, oil cylinder two moves upward and sampling probe 2 begins imbibition from crude oil 1, when oil cylinder two moves to desired location, imbibition this moment finishes, pressure switch 2K gets, control electromagnet 1DT gets electric, makes to turn to oil cylinder one commutation, and commutation finishes back pressure switch 1K and gets, 2K control 1DT gets electric the time, control 2DT dead electricity makes the 3-position 4-way solenoid operated directional valve get back to meta, has realized the liquid suction valve conversion, 1K gets electric back control 3DT and gets, 3-position 4-way direction valve commutation this moment, oil cylinder two moves downward, the beginning discharge opeing, the crude oil of drawing filters through strainer 4, enter blender 6 again, enter knockout 7 again, be discharged at last in the sample receiver 11, because the liquid that oil cylinder is two li is hydraulic oil, so in blender 6, fully allow crude oil mix, unhurried current, when oil cylinder two moved to the bottom, discharge opeing this moment finished, pressure switch 3K gets, 3K control 1DT dead electricity, the two-position four-way valve return makes to turn to oil cylinder one commutation, need time-delay several seconds this moment, move to terminal point until oil cylinder one, imbibition--3K control 3DT dead electricity, 2DT gets, oil cylinder two moves upward, when oil cylinder two moved to desired location, imbibition this moment finished, and pressure switch 2K gets.Circulation later on.
