Our company is engaged in dredging sand production professional service manufacturers, and adhere to the "unified goal, unified service, unified quality" business philosophy. Dredging sand in the process of use naturally consumes oil, good oil will reduce engine wear, prolong the service life of dredging vessels, so that the use of dredging sand more efficient, today with you to talk about how to choose the oil dredging sand:
① organic acids. It has corroded the surface of the metal, especially the corrosion of lead bronze bearings.
② gum. It is made from the oxidation of oil at high temperature and high pressure. The gum gathered in the lubricating oil film, formed the lacquer viscous material under the high temperature, so that the piston rings bonded in the annular groove and lost their role.
③ carbon deposition. The asphaltene formed by oxidative precipitation of glial is further oxidized at elevated temperatures, which will form hot spots, overheating and abrasion of the parts.
④ sludge. The oil is mixed with moisture, not only to make oil emulsion formation emulsion, and metal debris will also with the oil in the acid oxides of chemical reactions to generate iron soap. The oil, water, iron soap, and dust in the emulsion, metal shavings and oil, diesel oil are blended with each other to form sludge. Sludge condensation in the tubing, not only increase the oil flow resistance, even blocking the circuit, so that the lubricating system of the diesel engine loses its effect.
Above is to dig sand in the selection of oil needs to pay attention to some places, hope can help everyone, welcome to inquire.
