In the present invention, described oil sump body adopts low-carbon steel material; The outer surface of dry sump of the present invention must be done preservative treatment, handles as Dacroment.
Described dry sump uses with broad sense oil sump coupling.The lubricating circulatory system operating path of motor is: lubricant oil by flexible pipe and the bend pipe flange that is connected this flexible pipe, filler opening flange, is connected to the oil pump of motor from the broad sense oil sump, enters main oil gallery, is assigned to the lubricated cooling in each position; Lubricant oil after lubricated is got back in the oil sump body by drainback passage, then from the return tube of oil sump body and the flexible pipe that links to each other with return tube to oil scavenge pump, under the effect of oil scavenge pump, get back in the broad sense oil sump.A complete lubricating oil path circulation that Here it is.
Dry sump of the present invention is mainly used in motorboat engine, reduce the height of whole motor on the one hand, make motor be easy to be installed in the very limited space range, on the other hand, lubricant oil has improved the lubricating condition of motor through the filtration cooling of broad sense oil sump.The flowline connection to subsea of broad sense oil sump is located at the bottom simultaneously, no matter what kind of inclination hull produces, which tilt to direction, the oil pump filler opening of motor can both be drawn onto lubricant oil all the time, prevented that effectively the motor boat high speed operation is at crest and trough place, oil pump is inhaled less than lubricant oil or is sucked portion gas, produces insufficient lubrication, the pull-cylinder phenomena that may occur when serious.
Motorboat engine is a built-in motor, and motor boat travels on the water, requires the relative sealing of motor boat.The heat that motor produces can't distribute to the external world, and a large amount of heat accumulations produce harmful effect to motor boat hull material and safety in ship.Adopt dry sump and broad sense oil sump coupling, utilize external refrigeration water cooling lubricant oil, and a large amount of heats is brought into outside the ship.Guaranteed the Security of the lubrication effect and the motor boat of motor.
