Oil supply and injection equipment for marine diesel engine

Abstract

The invention discloses oil supply and injection equipment for a marine diesel engine. The oil supply and injection equipment comprises a bracket, an oil filter, a tank body, an observation window anda ball valve, wherein the tank body is a tapered structure which comprises an upper barrel body and a lower necking tube; the oil filter comprises a top cover and a filter screen; the top cover of the oil filter is covered by the bracket; the filter screen is inserted into the tank body from the top center of the tank body; the tank body is fixedly supported in the bracket; the ball valve is mounted on the lower part of the tank body; and the observation window is arranged on the peripheral wall of the barrel body of the tank body. The oil injection equipment can guarantee that enough lubricating oil can be injected into an oil supply unit motion part through simple gravitational potential energy action, guarantees the oil supply unit motion part to be lubricated sufficiently, avoids dryfriction, and avoids waste caused by lubricating oil leakage. The oil supply and injection equipment can be widely popularized to various lubricating fields of low-speed marine diesel engine main bearings, cam shaft bearings, and the like.

Description

technical field [0001] The invention relates to oil injection equipment for diesel engines, in particular to an oil supply oil injection equipment for marine diesel engines. Background technique [0002] At present, in the large-scale marine low-speed diesel engine market, two kinds of patented engines, Wartsila and MAN, are mainly manufactured and used. Take Wärtsilä main engine as an example. Its oil injection needs to be driven by power. It is connected with the crankshaft gear through the intermediate bearing seat, and the power is transmitted to the gear of the oil supply unit, and drives the lubricating oil pump gear and the fuel cam to move. At present, during the assembly of the main engine factory, the construction personnel generally simply add lubricating oil through the lubricating oil hole on the top of the oil supply unit housing. On the one hand, due to the high viscosity of the lubricating oil and the small clearance between the bearings, this simple operati...

AI Technical Summary

Problems solved by technology

On the one hand, due to the high viscosity of the lubricating oil and the small clearance between the bearings, this simple operation can only add a small amount of lubricating oil, which cannot achieve the purpose of fully lubricating the moving parts; Large oil leakage, serious waste, obvious defects

[0003] Therefore, the traditional oil injection method is likely to cause waste of lubricating oil leakage and insufficient oil injection.
