Description
Technical field
The invention belongs to technical field of measuring equipment, relate in particular to a kind of electrode of electromagnetic flowmeter cleaning method.
Background technique
Electromagnetic flowmeter is a kind of flowmeter being made based on faraday electromagnetic induction principle, its working principle is that:
When conductive medium flows through flowmeter, cutting flow meter electrode magnet exciting coil is to generate potential；Conduction different in flow rate
Property medium will generate different size of potential, and different flows is converted to by gauge outfit.Electromagnetic flowmeter is measuring at present
When the low conductivity mediums such as ethylene glycol, often in use for some time, electrode surface is easy to happen fouling and generates attachment,
Normal measurement is impacted, it is therefore desirable to sensor be removed at regular intervals, electrode surface is cleaned.This just leads
It sends a telegraph the small of magnetic flowmeter service efficiency to incite somebody to action, and certain cost of labor can be consumed, it is time-consuming and laborious.Such case is for big
It is especially serious when bore flowmeter.Therefore, a kind of novel electrode of electromagnetic flowmeter cleaning method how is developed, can be overcome
The above problem simplifies the cleaning step to electrode, improves equipment service efficiency, is the side that those skilled in the art need to study
To.
Summary of the invention
The present invention provides a kind of electrode of electromagnetic flowmeter cleaning methods, survey to low conductivity mediums such as ethylene glycol
When amount, electrode clean is realized without removal sensor shell, improves the working efficiency of electromagnetic flowmeter.
The specific technical solution that it is used is as follows:
A kind of electrode of electromagnetic flowmeter cleaning method comprising following steps: S1: the electrode for disconnecting flowmeter sensor connects
Connection between line end and the signal cable of flowmeter converter；S2: connect the electrode terminal of flowmeter sensor with it is adjustable
The output power line of alternating source；S3: adjustable alternating source starting exports alternating current to flowmeter sensor；S4: closing can
Alternating source is adjusted, the connection between the electrode terminal of flowmeter sensor and the output power line of adjustable alternating source is disconnected；
S5: the electrode terminal of flowmeter sensor and the signal cable of flowmeter converter are reconnected.
Compared with prior art, the present invention can be when measuring the low conductivity mediums such as ethylene glycol, without disassembly
Sensor housing realizes electrode clean, improves the working efficiency of electromagnetic flowmeter.
Detailed description of the invention
Present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments:
Fig. 1 is the working state schematic representation of the embodiment of the present invention 1；
Fig. 2 is the electrode clean status diagram of the embodiment of the present invention 1.
Each appended drawing reference and component names corresponding relationship are as follows:
1, flowmeter sensor；2, flowmeter converter；3, adjustable alternating source；11, electrode terminal；21, signal wire
Cable；31, output power line.
Specific embodiment
In order to illustrate more clearly of technical solution of the present invention, it is further described below in conjunction with each embodiment.
As shown in Figs. 1-2 it is the embodiment of the present invention 1:
A kind of electrode of electromagnetic flowmeter cleaning method, includes the following steps:
S1: it disconnects between the signal cable 21 in the electrode terminal 11 and flowmeter converter 2 on flowmeter sensor 1
Connection；
S2: the electrode terminal 11 of flowmeter sensor 1 is connect with the output power line 31 of adjustable alternating source 3；
S3: adjustable alternating source 3 starts, and exports alternating current to flowmeter sensor 1；
S4: adjustable alternating source 3, electrode terminal 11 and the adjustable alternating source 3 of disconnection flowmeter sensor 1 are closed
Connection between output power line 31；
S5: the electrode terminal 11 of flowmeter sensor 1 and the signal cable of flowmeter converter are again coupled to.
Its working principles are as follows:
Under detecting state, flowmeter sensor 1 and flowmeter converter 2 pass through electrode terminal 11 and signal cable
21 realize electrical connection, medium flow field overcurrent flowmeter transducer 1, and the signal generated is received by electrode, passed through electrode terminal 11
It is sent to signal cable 21, flowmeter converter 2 is recently entered and carries out signal processing.When detection conductivity it is relatively low and containing impurity compared with
When more media, it is larger to generate to electrode signal that electrode with Interface electric field existing for fluid will cause the adsorption phenomena of ion
It influences.At this point, exporting certain alternating current to flowmeter sensor 1 by accessing adjustable alternating source 3, order is adsorbed on electrode
On ion repulsion be greater than adsorption capacity, realize the desorption of ion.And for thicker attachment, it can be incited somebody to action by improving voltage
Then attachment breakdown is washed away by fluid.To realize without dismantle pipeline it is time saving and energy saving in the case where realize counter electrode
Two sides current potential, the purpose of cleaning electrode.
The above, only specific embodiments of the present invention, but scope of protection of the present invention is not limited thereto, it is any ripe
The technical staff of art technology is known in technical scope disclosed by the invention, any changes or substitutions that can be easily thought of, should all contain
Lid is within protection scope of the present invention.Protection scope of the present invention is subject to the scope of protection of the claims.
