It takes about 23 hours or so for operation of this procedure. Flushing flow rate: 2m/s. 、脫脂除銹清洗 Degreasing, antirust flushing process 目的是為了清除水沖洗難以去除掉的油污、氧化銹垢，使金屬露出活性表面。 inspect if there is any leakage for pipe joints and blind plates。沖洗流速大于 2m/s。 Circulating system connection and pressure test → water flushing → degreasing, antirust cleaning process → antirust, passivating process → purging, pigging process → oil flushing equipment connected → oil flushing → acceptance, resetting. 、試壓水沖洗 Pressure test and water flushing 將清洗水注滿被清洗系統(tǒng)內后，打開清洗泵開啟循環(huán)，檢查管線接口和封堵盲板有無泄漏，打開排氣閥檢查彎頭高位管道是否充滿液體，打開排污閥門將系統(tǒng)內的水迅速排空，這樣既沖洗了設備內部的雜質又可避免臨時系統(tǒng)內的雜質帶入設備內部，還可檢查系統(tǒng)有無滲漏和臨時管道設置問題。 Pipe nipple: provide flange and connector and other work fixture 管道短接用軟管 Soft hose of pipe joint 串油用相應工作沖洗油及輕質柴油。 Determine according to pipe diameter and pressure 油沖洗循環(huán)油箱一只 Circulating oil flushing tank 1 set 管道加熱器 配套 Pipe heater auxiliary equipment 管道振動器配套 Pipe vibrator auxiliary equipment 泵前過濾器、回油雙聯(lián)精密過濾器配套濾芯。, one for each 油沖洗專用裝備 流量 65m179。: two sets 清洗循環(huán)箱 、 1 立方各一只 Circulating cleaning tank 179。兩臺 Circulating cleaning pump 35m179。 Party A takes responsibility for equipment maintenance, the unit which is not to be flushed in the system should be detached or addition of temporary stub pipe, bypass, blanking it off by using blind plate, closing off the valve and other measures. According to the requirements made by Party B, Party A is responsible for separation circulating return circuit from any section irrelevant to the equipment. 、公用工程條件（由甲方提供） Conditions of public engineering (provided by Party A) 電 380V 3 相 4 線 50HZ Voltage: 380V 3phase 4wire 50HZ 清洗水 50m3 Flushing water 50m3 壓縮空氣 壓力 以上（可以采用船舶自備空壓設備） Compressed air Pressure: over (adopt selfcontained air pressor on the vessel) 、我方自備設備材料 Selfcontained equipment and material 循環(huán)清洗泵 35m179。 original system pump can be used for fresh water cooling system. 、清洗循環(huán)回路（略） Flushing process of circulating return circuit (omitted) 、甲方對設備檢修，系統(tǒng)內不參加清洗的裝置應拆除或加臨時短管、臨時旁路、加盲板堵死、閥門關死等措施。 六 . Preparation prior to chemical cleaning process 、清洗站的建立 Establishing a cleaning station 利用外接循環(huán)系統(tǒng)循環(huán)清洗，淡水冷卻系統(tǒng)采用原系統(tǒng)泵循環(huán)。 The oil in this oil flushing process: TOTAL special flushing oil can be used in the lubricating piping system。 PH value in the cleaning agent: , the cleaning process is pleted under the status of neutralization without any corrosion to metal, rubber in use. This product can be used by mixing with the cleaning liquid by proportion, easy to use。 This cleaning agent is a type of threeinone degreasing, rust cleaning and rustproof cleaning agent。 the circulating oil can be heated up to 4050℃ by electric heater。 The highest precision of the filter element on the filter used for Ф65amp。 We adopt this chemical cleaning process by using both circulating and immersing methods. Immersing method aims at using chemical cleanout liquid to fully contact with scaling substance. however, the purpose of circulating process is done by using the flushing action of circulation flow to flush out loosen, stripping impurities on the cleaning surface in the chemical reaction, which can speed up the diffusion rate of pretreatment filming agent in favor of electrodeposition process, . In favor of filming process, enabling it to be quickly filmed and to receive an excellent filming effect. 本次串油采用外接油泵（建議采用原系統(tǒng)油泵）循環(huán)，回油管道外接二級可切換管道過濾器，過濾器濾芯最高精度 5μ； 65 及 25 管徑二級過濾器濾芯最高精度 3μ，通過電加熱器加溫至 4050 度循環(huán)串油，壓力 。采用浸泡的目的是使化學清洗液與垢體充分接觸，而循環(huán)的目的是利用循環(huán)流動的沖刷作用將被清洗面疏松的和化學反應剝離的雜物帶出。還需要對 潤滑油管道系統(tǒng) 燃油供給管道系統(tǒng) 液壓油管道系統(tǒng)進行油沖洗工作。本次油沖洗是作為管系在連接主機或設備之前的預處理工作，在連接設備后正式投運前應進行再次油沖洗。對于新系統(tǒng)來說，設
