    絞吸式抽沙船對潤滑油有何要求?

    絞吸式抽沙船對潤滑油有何要求?
         絞吸式抽沙船操作簡單,易于控制。它是依靠船艉的臺車使鋼樁定位和步進,利用絞刀臂架兩測鋼纜與固定于挖槽兩測的錨,依靠鉸車牽引,兩廂擺動絞切泥沙物料,在一定的控制擺角下工作,將絞動的物料,經過輸泥管泵到堆積場。抽沙船的步進是由兩根樁交替運動,邁步向前。操作步驟是這樣完成的,由于抽沙船是鋼材制造,潤滑油是不可缺少的,對潤滑油有何要求呢?
         首先抽沙船長期在外面操作,冬夏溫度變化很大,有的地區晝夜溫差也大,因此要求潤滑油粘度隨溫度的變化要小,既要避免在溫度高時,油品粘度變得太低,以致不能形成潤滑膜,起不到應起的潤滑作用,又要避免在溫度低時粘度太高,以致起動、運轉困難;其次因為湖泊的環境惡劣,煤塵、巖塵、水分較多,潤滑油難免受到這些雜質的污染,所以要求挖泥船潤滑油要有較好的防銹、抗腐蝕、抗乳化性能;要求潤滑油當受到污染時,其性能變化不會太大,即對污染的敏感性要小。我們公司是專業制造抽沙船廠家,歡迎來公司考察。

    Cutter-suction type pumping large junk of lubricating oil?
          Cutter-suction type pumping large junk simple operation, easy to control. It is relying on the ship stern car make steel pile position and step by step, using the reamer boom two cables and fixed in excavated two test of anchor, depending on the winch tows, sta swinging ground sediment materials, cutting work under certain control pendulum Angle, the ground motion of the material, after dredging tube pump to the dump. Take large junk step is composed of two root pile alternating motion, moving forward. Steps are done so, due to the large junk is steel manufacture, lubricating oil is indispensable, if you have any requirements about oil?
          First draw large junk long-term operation in the outside, summer and winter temperature change is very big, some areas also big temperature gap between day and night, so the lubricating oil viscosity with temperature changes, both to avoid in high temperature, oil viscosity too low, so can't form the lubrication film, don't wake the lubrication effect, and to avoid the low temperature viscosity is too high, so that the starting, operating difficulties; Secondly because of bad environment of the lake, coal dust, ash, moisture content is more, lubricating oil by these impurities pollution, dredge lubricating oil is required to have good rust and corrosion resistance, demulsification performance; For lubricating oil when polluted, its performance is not too big change, the sensitivity for the pollution.Our company is specialized in manufacturing large junk manufacturer, welcome to our company.
