主機冷卻水系統由調溫器、淡水冷卻器、滑油冷卻器、淡水泵、海水泵、淡水箱（兼淡水膨脹箱）組成。 -
The equipped air valve design, can remove air with slight amount of vapors by suction as well as protect the cooling vapor from mixing into oil, so as to prolong the lifetime of oils in the pump
裝有氣鎮閥，在抽除含有少量水蒸汽的空氣時，打開氣鎮閥可避免水蒸汽凝聚后水混入油中，延長泵油的使用壽命。 -
The suitable oil flux during the circulating of transformer could be defined according to the difference of temperature between the oil and wind in the inlet and the cooling capacity of the wind cooling system ; besides the oil flux can be determined by ultrasonic, it can be estimated whether the oil is flowing equably by determining the oil flux in the branch pipes ; reducing the oil flux of the oil pump could be realized by controlling to change its frequency, which could not only save the energy, reduce the wastage, but benefit the transformer ' s circulating safely
變壓器運行中可根據進口油溫和進口風溫之差、風冷卻器的冷卻容量來確定合適的油流量；油流量可以通過超聲波法進行測量，測量油的分管流量還可判斷油流的均勻情況；降低潛油泵流量可通過潛油泵的變頻控制來實現，不僅節能降耗，對變壓器的安全運行也有著重要意義。 -
The piezoelectric - pump driven by piezoelectric - stack is a newly development trend, it can accommodate frequency and pressure in a large scale and control the output flux in precision. this pump will widely apply to transfusion, feed oil and clean the equipment in industrial automation, and scientific research, lab, chemical preparation and cooling of cpu etc. driven theory of piezoelectric - stack because the piezoelectric - stack is the core part of the pump that we designed, we should pay more attention to driven principle of the piezo - stack so that we can using it correctly. this paper introduces piezoelectric material and interrelated parameter, output characteristic and driven principle and driving type of piezoelectric - stack
壓電疊堆泵是一種以壓電疊堆作為驅動元件的微型泵，它是隨著mems的發展而發展起來的。本文提出利用壓電疊堆與柔性鉸鏈放大機構配合來驅動微型泵的橫隔膜，以達到泵送流體的目的。本文在查閱國內外大量文獻的基礎上，總結了國內外壓電疊堆泵的研究現狀，分析了壓電疊堆的動靜態特性，提出一種以壓電疊堆作為驅動源的壓電流體泵的構想。 -
And about 80 % of these transformers use natural oil circulation. more and more large power transformers used to using by pump and fan are cooling by onan for economy and environment protecting
目前電網上運行的電力變壓器大部分為油浸式變壓器，其中80以上是採用自然油循環的冷卻方式。 -
Quenching hot oil is forced cooling by outer circulation of oil - pump and heat exchanger, so oil - cooling rate is high
