Description
Technical field
The invention belongs to detection with warning system technical field, be applied to reciprocating plunger pump plunger leakage rate detection with
Report to the police, be specifically related to the detection of plunger leakage rate and the warning system of a kind of reciprocating plunger pump.
Background technology
The industries such as the most each oil field of reciprocating plunger pump, chemical industry are all widely used.At oil field plunger pump often quilt
In the techniques such as high pressure water injection, polymer injection, note alkali liquor, plunger displacement pump as in oil extraction in oil field technique capital equipment, post
Plug and sealing thereof are then the critical components in plunger displacement pump equipment.Leakage rate size in the injecting process, between plunger and filler
It it is the properly functioning key parameter of decision device.A small amount of medium (water, polymer, alkali liquor can be taken out of during plunger motion
Deng).Along with prolongation, the medium taken out of of the time of operation can be cumulative, without effective monitoring means monitoring leakage amount,
Equipment long-play ultimately results in seal failure, causes equipment fault.
Summary of the invention
The present invention solves the deficiencies in the prior art, it is provided that the detection of plunger leakage rate and the warning of a kind of reciprocating plunger pump
System, is artificially observed present real-time monitoring by what original equipment ran plunger amount of leakage, the early warning that overflows, manually has a purpose
Intervene, it is to avoid equipment long-play ultimately results in seal failure, the problem that causes equipment fault.
The technical solution adopted in the present invention is: the plunger leakage rate detection of a kind of reciprocating plunger pump and warning system,
Including reciprocating pump plunger and be located at the return duct of reciprocating pump plunger side, discharge opeing case, fluid level transmitter, drain tube, electromagnetic valve with
Intelligent control cabinet, described reciprocating pump plunger lower end has drainage port, and described drainage port connects with the import of return duct, described backflow
The outlet of pipe connects with the import of discharge opeing case, and the described outlet of discharge opeing case connects with the import of drain tube, described fluid level transmitter
Being installed on discharge opeing case upper end, described electromagnetic valve is installed on drain tube pipeline, and fluid level transmitter all passes through signal with drain tube
Line is connected with Intelligent control cabinet.
Compared to prior art, the invention have the benefit that by perfect intelligent early-warning system plunger pump plunger shaft
Plug amount of leakage carries out detecting and early warning, original equipment run the artificial observation real-time prison till now out of control of plunger amount of leakage
Control, the early warning that overflows, manually has purpose intervention, has both improved the operational efficiency of equipment, the most also improves operation and maintenance department
Work efficiency, be finally reached and change in time plunger and change impaired plunger or filler in time, it is ensured that plunger displacement pump safe operation.
Accompanying drawing explanation
Fig. 1 is present configuration schematic diagram.
Detailed description of the invention
The present invention is described in detail with detailed description of the invention below in conjunction with the accompanying drawings.
The plunger leakage rate detection of a kind of reciprocating plunger pump and warning system, structure is as it is shown in figure 1, include reciprocal pump plunger shaft
Plug 1, and it is located at the return duct 2 of reciprocating pump plunger 1 side, discharge opeing case 3, fluid level transmitter 4, drain tube 5, electromagnetic valve 6 and intelligence
Switch board 7, described reciprocating pump plunger 1 lower end has drainage port 11, and described drainage port 11 connects with return duct 2 import, described time
The outlet of flow tube 2 connects with the import of discharge opeing case 3, and the outlet of described discharge opeing case 3 connects with the import of drain tube 5, described liquid level
Transmitter 4 is installed on discharge opeing case 3 upper end, and described electromagnetic valve 6 is installed on drain tube 5 pipeline, and fluid level transmitter 4 and drain tube
5 are all connected with Intelligent control cabinet 7 by holding wire 8.
Wherein, the plungers pump plunger amount of leakage being collected in discharge opeing case 3 is carried out by the PIC controller in Intelligent control cabinet 7
Monitoring in real time, analytical data, judgement early warning and protection output.
Discharge opeing case 3 is for centralized collection and stores plungers pump plunger amount of leakage.
Fluid level transmitter 4 monitors the liquid level of discharge opeing case 3 in real time.
The operation principle of the present invention:
By the PIC controller in Intelligent control cabinet 7, system process is programmed.Plunger leak liquid passes through discharge opeing
Case 3 is collected, and is acquired liquid level by fluid level transmitter 4, and PLC control system carries out data processing and inversion, passes through
Leakage liquid level in discharge opeing case 3 exports leakage rate ml/h to the Integral Processing of time.Reveal liquid level arrival discharge opeing case 3 and height is set
Position, electromagnetic valve 6 automatically opens up discharge opeing.After electromagnetic valve 6 cuts out, leakage rate recalculates.According to the national standard rule to leakage rate
Determine to be configured early warning value by program.Leakage rate exceedes early warning value, system meeting voice message leakage amount abnormity, and uploads on duty
Room.Night shift room sends staff scene to process.
At present, Changqing oilfields is moved water flooding pump station and has done the detection of plunger leakage rate, Design of Alarm System, pass through feedback letter
The continuous service efficiency of breath equipment improves 20%, and also there is suitable raising in the life-span of plunger and filler.
Invention achieves the centralized collection to plunger amount of leakage, data analysis, judgement early warning, the effect of automatic-discharging,
And by the way of artificial intelligence, operator on duty is carried out voice reminder and wireless uploads.
Above-described embodiment, simply presently preferred embodiments of the present invention, not be used for limiting the practical range of the present invention, thus all with
The equivalent variations that content described in the claims in the present invention is done, within all should being included in scope of the invention as claimed.
