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.
