绞吸式抽沙船对润滑油有何要求？
     绞吸式抽沙船操作简单，易于控制。它是依靠船艉的台车使钢桩定位和步进，利用绞刀臂架两测钢缆与固定于挖槽两测的锚，依靠铰车牵引，两厢摆动绞切泥沙物料，在一定的控制摆角下工作，将绞动的物料，经过输泥管泵到堆积场。抽沙船的步进是由两根桩交替运动，迈步向前。操作步骤是这样完成的，由于抽沙船是钢材制造，润滑油是不可缺少的，对润滑油有何要求呢？
     首先抽沙船长期在外面操作，冬夏温度变化很大，有的地区昼夜温差也大，因此要求润滑油粘度随温度的变化要小，既要避免在温度高时，油品粘度变得太低，以致不能形成润滑膜，起不到应起的润滑作用，又要避免在温度低时粘度太高，以致起动、运转困难；其次因为湖泊的环境恶劣，煤尘、岩尘、水分较多，润滑油难免受到这些杂质的污染，所以要求挖泥船润滑油要有较好的防锈、抗腐蚀、抗乳化性能；要求润滑油当受到污染时，其性能变化不会太大，即对污染的敏感性要小。我们公司是专业制造抽沙船厂家，欢迎来公司考察。  

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.
