After all kinds of mechanical seal damaging are estimated, it is considered that the seal malfunction is mainly because of cooling-water scaling. 统计了机械密封损坏的各种情况,认为冷却水结垢是密封失效的主要形式。
After the hollow mechanical punching device has been successfully developed, the scaling problem has been eliminated and the unit output has maintained at 1 000 kW. 在试制成功空心机械通井器,消除了地热井的结垢问题后,机组出力一直稳定在1000kW。
The Peroxide Bleaching of Mechanical Pulps by Partial Substitution of Mg ( OH)_2 for NaOH can be Decreased Calcium Oxalate Scaling 过氧化物漂白机械浆过程中用氢氧化镁代替氢氧化钠以降低草酸钙结垢
In order to ensure the generator insulate from ground and avoid the hollow copper wires plugged by mechanical impurities 、 scaling and corrosion deposition, there is high special requirement on cooling water of the generator. 为了保证发电机对地绝缘和防止空芯铜导线内因机械杂质、结垢、腐蚀产物沉积等原因造成堵塞,国内外均制定了相应的水质控制指标和措施,对冷却用水要求很严格。
