Problems solved by technology

The hard connection of seamless steel pipe is simple in structure, easy to manufacture, and low in cost, but the diesel engine will generate vibration and torsion when it is running. Long-term vibration and torsion will easily cause fatigue and rupture of the hard connection interface, resulting in leakage of lubricating oil or sewage into the lubricating oil circulation storage cabin and cause safety accidents; the rubber skin soft connection can well absorb the vibration and torsion generated by the diesel engine when it is running, but the rubber material is easy to age and requires frequent maintenance and replacement. The maintenance and management costs are high, and the maintenance and management are not timely. It is easy to cause oil leakage and cause safety accidents

Abstract

The invention relates to the technical field of shipbuilding, and discloses an oil return connection device. The oil return connection device includes a bellows, a guide pipe, a first seat plate and a second seat plate, and the first seat plate is fixedly arranged on the oil pan of a diesel engine. Above, the first seat plate is provided with a first opening matching the bellows, the second seat plate is fixedly arranged on the lubricating oil storage compartment, and the second seat plate is provided with an oil return hole connected with the lubricating oil storage compartment The second opening of the bellows, the upper end of the bellows is fixedly connected to the first seat plate, the lower end of the bellows is fixedly connected to the second seat plate, the guide tube is arranged in the bellows, and the oil inlet end of the guide tube is connected to the diesel engine oil pan The oil discharge hole of the guide pipe, the oil outlet end of the guide pipe is connected to the oil return hole of the lubricating oil storage tank through the second opening, and the oil inlet end of the guide pipe is provided with a filter screen. The invention has the advantages of convenient assembly, high working efficiency, effective absorption of the vibration generated by the diesel engine, high stability, high safety and long service life.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to an oil return connection device. Background technique [0002] Ships above 10,000 tons are usually equipped with dry lubricated diesel engines as power plants during construction. The lubricating oil circulation storage tank of dry lubricated diesel engine is set independently from the diesel engine. The lubricating oil circulation storage tank of the 10,000-ton marine diesel engine is usually set independently directly under the oil pan of the diesel engine, and the lubricating oil is passed through at least one oil return hole. The finished lubricating oil is collected from the oil pan and returned to the lubricating oil circulation storage tank for recycling. [0003] At present, there are mainly two ways to connect the oil return port of the diesel engine and the lubricating oil circulation storage tank: seamless steel pipe hard connection and rubber skin soft connectio...
