Abstract
The invention discloses a heating method for testing a temperature element of a generator set. According to the method, a temperature element to be tested and a standard temperature detecting probe are inserted in a dry furnace, scrap iron is injected in the dry furnace from the top to the bottom till the scrap iron reaches a furnace opening and fully fills the cavity of the dry furnace; when the dry furnace is started for heating, the scrap iron transfers heat to heat the temperature element to be tested and the standard temperature detecting probe, and temperature signals of the temperature element to be tested and the standard temperature detecting probe are compared so as to test the temperature element. The heating method has the advantages that a plurality of isothermal blocks adapted to the specification and model of the temperature element do not need to be made, the testing cost of the temperature element is reduced, the testing time interval is shortened effectively, and the testing efficiency of the temperature element is improved.
Description
Technical field
The present invention relates to the heating method of a kind of genset temperature element (TE) verification.
Background technology
The power generator group is in service, needs to detect a plurality of vital temperature signals, and whether these signals accurately will directly have influence on the normal operation of unit.Like the coil temperature signal on the generator, the main steam temperature signal on the boiler and the bearing temperature signal on the steam turbine or the like.They all are the temperature regimes that has very demonstrated unit each link under running status intuitively, so that whether operations staff's reference normally makes judgement to set state.Above-mentioned temperature signal adopts temperature element (TE) to implement to detect usually, and each temperature element (TE) is directly connected to the accuracy of temperature detection; Therefore temperature element (TE) decide inspection and verification seems particularly important.
The stem body stove is adopted in the verification of general temperature element (TE), and like the G700LRI stem body stove of York company, the temperature range of this stove heating is 50 ℃～700 ℃, and stove directly is 64mm, and stove is 160mm deeply, verification condition that can the satisfied temperature element.In the checking procedure; Because temperature is not an equilibrium state in the non-uniform temperature in the stove, stove, therefore the isothermal piece is arranged in the stove; Have a plurality of through holes on the isothermal piece; Heated with the stem body stove in a plurality of a plurality of through holes that inserted the isothermal piece by school temperature element (TE) and standard temperature probe, and guarantee to be positioned at same plane, with the consistance of assurance temperature by school temperature element (TE) and standard temperature probe; Export the verification that signal can be implemented temperature element (TE) through handling by school temperature element (TE) and standard temperature probe.The employing of isothermal piece has guaranteed the consistance of temperature, but also has certain defective, and temperature element (TE) has the plurality of specifications model in the genset, therefore must make the isothermal piece of a plurality of adaptive temperature component specification models, has improved the cost of verification operation; When temperature element (TE) is changed verification or duplication check, need wait the cooling of isothermal piece simultaneously, so that implement verification next time, but the cooling of isothermal piece slowly, and is consuming time longer, had a strong impact on the verification efficient of temperature element (TE).
Summary of the invention
Technical matters to be solved by this invention provides the heating method of a kind of genset temperature element (TE) verification; This method avoids making the isothermal piece of a plurality of adaptive temperature component specification models; Reduced temperature element (TE) verification operating cost; And effectively shorten verification interval time, improved the verification efficient of temperature element (TE).
For solving the problems of the technologies described above; The heating method of genset temperature element (TE) of the present invention verification comprises that verification uses the stem body stove, will be inserted in the said stem body stove by school temperature element (TE) and standard temperature probe; Said stem body stove from up to down injects iron filings to fire door and is full of the stem body furnace chamber; Start the stem body stove and heat, iron filings conduct heat and are implemented to heat by school temperature element (TE) and standard temperature probe in the stem body stove, are relatively implemented verification by the temperature signal of school temperature element (TE) and standard temperature probe.
The grain size of above-mentioned iron filings is the 1-18 order.
Because the heating method of genset temperature element (TE) of the present invention verification has adopted technique scheme; Be about to inserted in the stem body stove by school temperature element (TE) and standard temperature probe; The stem body stove from up to down injects iron filings to fire door and is full of the stem body furnace chamber then; Start the stem body stove and heat simultaneously, iron filings conduct heat and are implemented to heat by school temperature element (TE) and standard temperature probe, are relatively implemented verification by the temperature signal of school temperature element (TE) and standard temperature probe.This method avoids making the isothermal piece of a plurality of adaptive temperature component specification models, has reduced temperature element (TE) verification operating cost, and effectively shortens verification interval time, has improved the verification efficient of temperature element (TE).
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is done further detailed description:
Fig. 1 is the structural representation of stem body stove in this method.
Embodiment
As shown in Figure 1; The heating method of genset temperature element (TE) of the present invention verification comprises verification with stem body stove 1, will be inserted in the said stem body stove 1 by school temperature element (TE) 3 and standard temperature probe 4; Said stem body stove 1 from up to down injects iron filings 2 to fire door and is full of stem body stove 1 inner chamber; Start stem body stove 1 and heat, iron filings 2 conduct heat and are implemented to heat by school temperature element (TE) 3 and standard temperature probe 4 in the stem body stove 1, are relatively implemented verification by the school temperature element (TE) 3 and the temperature signal of standard temperature probe 4.
In order to make iron filings fill up the stem body stove fully, and make and to be contacted fully that the grain size of iron filings is had certain requirement by school temperature element (TE) and standard temperature probe.Its grain size is selected the 1-18 order for use; Such iron filings just can meet the requirement of fully filling up whole stem body stove; Make to be contacted closely by between school temperature element (TE) and standard temperature probe and the iron filings, do not have air, guaranteed by the consistance of school temperature element (TE), standard temperature probe and stem body furnace temperature.
This method adopts iron filings to replace traditional isothermal piece; Only need iron filings are injected the stem body furnace chamber; Insert the temperature element (TE) and the standard temperature probe of stem body stove with parcel; Played the same consistent effect of temperature of isothermal piece, and it is for use to need not to make a plurality of isothermal pieces according to the temperature element (TE) specifications and models, has saved the verification cost; Simultaneously when replacing of need temperature element (TE) or duplication check; Only need the iron filings in the stem body stove are poured out furnace chamber; And the iron filings of pouring out furnace chamber will cool off fast, by the temperature element (TE) in school after arranging again on the stem body stove, the iron filings that inject cooling can begin the verification operation once more; So avoid the long-time cooling of isothermal piece, obviously improved the verification efficient of temperature element (TE).
Claims (2)
