Description
Technical field
The present invention relates to a kind of monitoring method more particularly to a kind of installations and load monitoring side suitable for rigid hanger
Method.
Background technique
High temperature and pressure steam-water pipe is the extremely important component part in power plant and chemical plant, in high temperature and pressure steam-water pipe
When system suspension and support type selecting, vertical pipe (following abbreviation standpipe) partially can only must also configure one group of rigid hanger or rigidity
Tension bracing device, it is the important component part of high temperature and pressure steam-water pipe suspension and support, especially four big pipelines (main steam line,
High-temperature reheat pipe road, low-temperature reheat pipe road, high-pressure feed water pipeline, high pressure turbine by jet chimney and low voltage bypass steam
Pipeline).Standpipe rigid hanger plays bearing load, and restriction conduit is displaced and distributes standpipe thermal expansion curve amount, prevents under pipeline
Heavy effect.Standpipe rigid hanger, which loses, to be carried, and can generate safely significant impact to pipe-line system.
In view of the above shortcomings, the designer, is actively subject to research and innovation, it is a kind of suitable for rigid hanger to found
Installation and load monitoring method, make it with more the utility value in industry.
Summary of the invention
In order to solve the above technical problems, the object of the present invention is to provide a kind of installation suitable for rigid hanger and load prisons
Survey method.
Installation and load monitoring method suitable for rigid hanger of the invention, it is characterised in that the following steps are included:
Step 1 installs strain transducer on rigid hanger, is installed to pipe-line system and before use, reads sunpender
Upper cold conditions strain value εC；
Step 2 inquires current rigid hanger material corresponding elastic modulus E under normal temperature environment0, according to relational expression σC=
E0×εCCalculate tensile stress sigma when cold conditionsC, obtain the actual installation load F of rigid hangerC；
Step 3, the installation load F with designSCIt is compared and adjusts accordingly；
Step 4 reads cold conditions strain value ε on sunpender after pipe-line system stable operationH；
Step 5 inquires current rigid hanger material corresponding elastic modulus E under normal temperature environmentT, obtain rigid hanger
Real work load FH；
Step 6, the work load F with designSHIt is compared and adjusts accordingly.
Further, the above-mentioned installation and load monitoring method suitable for rigid hanger, wherein in the step 2,
If the sectional area of the rigid hanger where strain transducer installation site is S, calculates and obtain actual installation load FC=S × σC, with
The installation load F of designSCIt is compared, if when beyond the deviation range allowed, by spending blue bolt or tightening nut tune
Load is saved, installation load F is enabledCIn setting range.
Further, the above-mentioned installation and load monitoring method suitable for rigid hanger, wherein the step 4
In, read thermal state strain value ε on rigid hangerH, according to relational expression σH=ET×εHAnd FH=S × σH, preamble data is counted
It calculates, obtains real work load FH。
Further, the above-mentioned installation and load monitoring method suitable for rigid hanger, wherein, will in step 6
What is obtained eats hot load FHIt is compared with preset value, if it is different from preset value, and be more than the error range of setting, then it is determined as
It is unqualified.
According to the above aspect of the present invention, the present invention has at least the following advantages:
1, it can implement to supervise rigid hanger volume load, tensile stress when obtaining its cold conditions and eat hot load, just
It is managed in time in rear end personnel.
2, data acquiring mode is simple, can be obtained by computer aided calculation, and data precision is high.
3, judgement can also be executed using software auxiliary, be realized automatically-monitored under no supervision.
The above description is only an overview of the technical scheme of the present invention, in order to better understand the technical means of the present invention,
And can be implemented in accordance with the contents of the specification, with presently preferred embodiments of the present invention, detailed description is as follows below.
Specific embodiment
With reference to embodiment, the embodiment of the present invention is furthur described in detail.Following embodiment is used for
Illustrate the present invention, but is not intended to limit the scope of the invention.
Installation and load monitoring method suitable for rigid hanger, it is characterised in that the following steps are included:
Firstly, installing strain transducer on rigid hanger, being installed to pipe-line system and before use, reading on sunpender
Cold conditions strain value εC。
Later, current rigid hanger material corresponding elastic modulus E under normal temperature environment is inquired0, according to relational expression σC=E0
×εCCalculate tensile stress sigma when cold conditionsC。
Then, the actual loading F of rigid hanger material is obtainedC.Specifically, if where strain transducer installation site
The sectional area of rigid hanger is S, calculates and obtains actual loading FC=S × σC.Later, with the installation load F of designSCCompared
Compared with.It, can be by spending blue bolt or tightening nut to adjust load when deviation range beyond permission.
Then, after the operation of pipe-line system normal table, thermal state strain value is read.It is exactly in pipeline system for specific drawing
It unites after stable operation, obtains rigid hanger and eat hot load F when eating hotH.In order to obtain more accurate numerical value, avoid out
It now judges by accident, needs to read thermal state strain value ε on rigid hangerH, according to relational expression σH=E0×εHAnd FH=S × σHIt calculates and obtains,
Eat hot load FH。
Finally, judgement is compared to step 4 data.During this period, hot load F will be eatenHIt is compared with preset value,
If it is different from preset value, and be more than the error range of setting, then it is determined as unqualified.
It can be seen that after applying the present invention by above-mentioned character express, gather around and have the following advantages:
1, it can implement to supervise rigid hanger volume load, tensile stress when obtaining its cold conditions and eat hot load, just
