Description
Technical field
The utility model is related to key water control project dam technical fields, and in particular to one kind is used for Radial Gates at Hydropower Plant rubber water sealing
The dedicated unit of spray lubrication water.
Background technology
Pavilion mouthful key water control project dam sets 8 surface spillways altogether, one fan extended-top type arch gate of setting, bottom per hole
Bank elevation ▽ 437.58m, table hole Segmental service gate port size 14.0m (width) × 23.0m (height).Working radial gate uses " P " type
Rubber water sealing and arc door side sealing embedded part cooperation sealing, design and installation specification be left and right sides sealing rubber respectively with siding track
It connects completely, unilateral precommpression 5mm.
Table radial door will inevitably carry out contact friction in opening-closing process between side sealing and siding track embedded part, if
There is no the lubrication of enough external coolants, with the frequent keying of gate, rubber water sealing is in dry friction simultaneously, can produce
Raw a large amount of frictional heat if maintaining operation for a long time under this operating condition, can constantly reduce the physical of rubber water sealing
Can, while the sealing performance of the sealing of gate entirety is also reduced, not only shorten and reduce the service life of water seal, but also
It is serious to be likely to result in a large amount of leaks of gate so as to lead to the increase of water leakage of gate amount, it can particularly be caused in flood season
Safety of Flood Control hidden danger.On the other hand, due to the shortening of water seal service life, while the operation expense of gate is also increased.
To avoid the generation of the unfavorable factor in above-mentioned gate operational process, at present in table radial door opening-closing process, water seal
Lubrication water is fetched water by artificial and is carried out shower, it is ensured that water seal is not destroyed.And manually fetching water can only take from the dam fire-fighting place of fastening
Water, lubrication water water intaking distance is remote, personnel labor intensity is high, heavy workload, but also can not ensure that arc door is held in opening-closing process
The continuous cooling of supply incessantly lubrication water, and the lubrication water provided can not meet the needs of lubrication.More importantly
In flood season urgent flood discharge, it can not just be met the requirements, can only be done in Jeakage through Sluice Sealant at all using artificial water application's lubricating system
It is operated under friction condition.
In conclusion to ensure the good operating condition of " P " type rubber water-proof water seal in arc door opening-closing process, with reference to table hole
The arc door method of operation and dam industrial water deployment scenarios, it is necessary to be transformed to water seal lubricating system unfavorable at present, thoroughly
It solves the problems, such as that arc door leads to damage due to side sealing dry friction when opening and closing and operating, improves equipment reliability of operation and peace
Quan Xing.
