Common rail type air cylinder oil injection lubricating system

Abstract

The invention discloses a common rail type air cylinder oil injection lubricating system. The common rail type injection principle is adopted, and only one oil product, namely, air cylinder lubricating oil is included. The common rail type air cylinder oil injection lubricating system comprises an air cylinder lubricating oil supply component, an air cylinder lubricating oil common rail pipe component, an oil injection gun component and a control component. The air cylinder lubricating oil supply component, the air cylinder lubricating oil common rail pipe component and the oil injection gun component are sequentially connected. The control component is connected with the air cylinder lubricating oil supply component, the air cylinder lubricating oil common rail pipe component and the oil injection gun component and controls the air cylinder lubricating oil common rail pipe component to adjust the lubricating oil supply pressure of the air cylinder lubricating oil supply component according to the requirements and controls the oil injection gun component to adjust the lubricating oil injection time and lubricating oil injection amount according to requirements. Flexible and soft control over the air cylinder oil injection amount, the oil injection pressure and the oil injection timing is achieved, the control precision and the control freedom degree are improved, the air cylinder lubricating condition is improved, the air cylinder oil injection efficiency is improved, and the air cylinder lubricating oil consumption is reduced. The common rail type air cylinder oil injection lubricating system has the beneficial effects of being compact in structure, stable in oil injection pressure and good in lubrication effect and is suitable for large-power ship diesel engines such as a low-speed two-stroke diesel engine.

Description

technical field [0001] The invention relates to an oil injection lubrication device for power machinery, in particular to a common rail cylinder oil injection lubrication system for a marine high-power diesel engine, which belongs to the technical field of diesel engines. Background technique [0002] Marine low-speed diesel engine cylinder oil injection system is one of the important components of the diesel engine. The lubrication condition between the cylinder liner and the piston of the diesel engine directly affects the mechanical efficiency of the main engine and the life of the cylinder liner, thereby affecting the fuel consumption rate of the main engine and the maintenance cost of parts. At the same time, the daily consumption of lubricating oil generated during the operation of the main engine is also an important part of the operating cost of the main engine. Therefore, on the premise of satisfying the lubrication conditions of cylinder liners and piston rings, di...

Problems solved by technology

[0003] At present, the widely used electronically controlled cylinder oil injection system adopts the injection principle of pressurizing the low-pressure cylinder lubricating oil through the high-pressure servo oil system. Therefore, there are not only two types of oil in the overall system: servo oil and cylinder lubricating oil , and the hydraulic amplifying mechanism in the oil injection system not only complicates the structure of the system, but also greatly limits the responsiveness and control accuracy of the system, etc.
