【正文】 lue. Overhaul its seal, found by plugging material was washed run, and certainly some pits scouring by water into inner seriously. So according to the original design of the seal clearance will lose its practical significance, and now will manufacturers in the overhaul of the original ~ mm to mm, and gap with highpressure airproof material change, the effect is good.High add entrances water room clapboard leakage. A power plant in operation of water supply temperature unit obviously low (℃ for 240 ℃) design value. Found in VSD repair gateway water board is very big, and impact, gap between inner cavity with clapboard leave, make water to shortcircuit, after the flood water temperature, obviously rises, can reach 230 ℃. scanty water system automatically puttinginservice proactively adverse We plant of the 8th high add, hydrophobic automatic can39。t pitch without water, frequent operation. Scanty conduit scour serious, vibration is very big, the carbon steel elbow frequently blunt bad. After the high water regulator with hydrophobic moved to the deaerator39。s platform, which helps to overe scanty conduit elbow erosion serious, the problems of pipeline vibration. water meter and water level signal devices cannot normal operation Water meter each power plant is the mon leakage problem of old factory, our original high water position idea often appear leak phenomenon, some power station 1 machine has been added into high since a leak, electricity substation contacts shortly after bad, see not, reflecting water meter with reality. about high add scanty water system Deal with high add drain system the three mon fault blocking, vibration and wear is to ensure safe operation, high added an important TouRuLv high plus improve factors. Investigate third big failing, are the root of due to high add hydrophobic will produce twophase fluid flow. According to concerning material is introduced from singlephase flow, when fluid for twophase flow, the flow velocity will expand 20 times above, resistance increase exponentially. We should pay attention to the following problems in operation. (1) maintain high added to the operation level, is to guarantee the normal operation of the high plus important condition. Water is too low or high water level and operate in economic security caused great harm. When no water at runtime, by the steam trap directly into the next level high piping and steam side, thus making the s
