| , small steam turbine installation easy neglected problems , relationresultThis simple method for hoisting .Often in the rotor thrust flange and bearing thrust Wagang contact moments ,lack of guiding device ,will thrust tile alloy face gnawed away .
Especially in the last assembly hanging ,if the thrust tile gnawed away .No longer hanging out ,not discovered in time . The formation of serious hidden danger ,eventually may lead to axial movement of such quality accident .
Correct erection method should be .In hoisting seat must use guide device due to the design drawings made no demands ,here introduced steam turbine plant often use rely on the device itself is oriented in hoisting method ,offer reference of turbine rotor lift to the lower bearing seat is at the top of .
The setting ,when the rotor thrust flange diameter near the thrust shaft J left corresponding depression contain about 5 to about 10mm .Stop falling .Operation of Artemisia tool will thrust and radial bearing in the bearing body from tile pillow h up a bit.
So that the thrust bearing half ring depression fossa anastomosis on the rotor shaft corresponding thrust disc .When a bearing is set into the bearing thrust plate ,lower still in tile pillow fossa .
Played a guiding sleeve role then command crane rotor and bearing body falling until the seat end .3 new steam line blowing steam line blowing and cleaning of steam turbine operation safety is crucial .
Purge the scope and requirements of the electric power construction in ≤Hyunstudents coins mounted hang my strip computer application l ,.Exploration of China installation of computer application in enterprise road a blue ( by my calculation in China Installation Association Miss installation industry early in 80 time initial stage begins to use computer ,} years .
There are many successful experience and advanced typical case .Some enterprises have considerable strength and made considerable achievements, but outspoken. Both domestic and foreign computer development situation comparison.
But compared with other industries .Installation industry nots allow hopeful .When saw many new start unit still taking antecedent units has traversed a tortuous path .Deeply deplored and upset.
We must not repeat the Tuition ,should sum up experience seriously ,causing installation business leaders on the computer ,in order to further promote the installation of computer work development .
L installation industry the present situation of computer application according to the China Association for the installation of Computer Department of the member units surveys .The installation of computer application still is in dispersive ,spontaneous ,progressive primary level, the whole industry computer applications is extremely unbalanced state to have the following situations: 1.
1 minority business enterprise has formed commonly used computer environment ,development direction is clear ,the enterprise management has played an important role, some to the production technology ,project construction ,design drawings to extend in a direction ;some have networking .
Not only embodies the computer and the ,and obtain obvious economic benefit and social benefit .These units of the computer has reached a considerable scale .A cairn master .
.. Han 2 ) strong technical force ,the computer room in general have independent as Shanghai city industrial equipment installation company system in intelligent buildings weak system design installation break a new path ;Guangzhou City electrical installation company large-scale development of computer ,adapted from labor intensive to manage intensive transformation to achieve efficient ,accurate .
,real time requirement .Some enterprises with machine although later. But due to the right direction ,strength is great ,can achieve a breakthrough progress .2 most units will have the computer application in all aspects of enterprise management .
Such as budget ,material ,labor ,archives ,financial general instead of manual operation ,improves the working efficiency and management quality but mainly rely on a long exploration gained certain experience.
It is difficult in the short term has make a spurt of progress in the development of .In the organization .The computer room is not generally independent of the application software, depend too much on the manager skill level and enthusiasm ,easily because of personnel changes ,organization adjustment and other factors which the accumulation of hard work results be destroyed on one day .
1.3 some units due to the lack of professionals and the application software management system is lax or on .The significance and characteristics of computer understanding enough. Failed to give due to support and interpreted .
Application is very limited ,long term can not be opened, computer personnel have the fear of difficulties .1.4 still have quite one part enterprise trapped poor efficiency and operational difficulties.
On the role of computer or lack of awareness and understanding ,to date and acceptance has been clearly defined but some units only pay attention to the main steam pipeline sweeping and cleaning.
Ignoring .Various branch ,Abercrombie vente,bypass pipe blowing and cleaning it is quite harmful for the main steam isolation wide bypass pipe ,main steam bypass system tube shaft seal steam inlet pipe ,the main pumping device ,auxiliary air ejector steam inlet pipe ,steam-driven oil pump inlet pipe of general ,who guide selection of new steam pipe .
Regardless of the size of the pipe diameter, must like a main steam pipe by sweeping and cleaning .In order to ensure the smooth and safe operation of the test ( El i996 C3 received one
