Dry type oil pan oil supply device applicable to large-inclination-angle diesel engine

Abstract

The invention belongs to the internal field of internal combustion engines and provides a dry type oil pan oil supply device applicable to a large-inclination-angle diesel engine. According to the dry type oil pan oil supply device applicable to the large-inclination-angle diesel engine, two partition plates perpendicular to the bottom face of a dry type oil pan are arranged at the bottom of the dry type oil pan; an oil storing groove is formed between the two partition plates, and the two sides of the oil storing groove are each provided with an oil collecting groove of an open structure; an oil inlet pipe is arranged in each oil colleting groove; the flange ends of the oil inlet pipes are connected with an oil inlet of a two-stage parallel connection gear pump; one end of an oil outlet pipe arranged in the oil storing groove stretches out of the oil storing groove and is connected with an oil outlet of the two-stage parallel connection gear pump; the dry type oil pan oil supply device is further provided with an oil sucking pipe communicated with an engine oil pump of a diesel engine lubricating system; and the other end of the oil sucking pipe is connected with a suction filter located at the bottom of the oil storing groove in an inserted connection manner. The dry type oil pan oil supply device applicable to the large-inclination-angle diesel engine effectively solves the problem that under the conditions that the speed change and the inclination are large during turning of the diesel engine, normal lubrication of the diesel engine cannot be achieved, and the inclination angle of work of the diesel engine is greatly improved.

[0003] Lubricating oil is like the blood flowing in the diesel engine. Good lubrication of the diesel engine under various operating conditions is the key to ensure the long-term stable operation of the machine. As an important part of the diesel engine lubrication system, the oil pan is the source of lubricating oil recovery and supply ;Due to the different working conditions of the diesel engine, different requirements are put forward for the design of the oil pan of the diesel engine; as we all know, the state of the lubricating oil is liquid at room temperature, and when the diesel engine is in use, the speed of the engine oil is accompanied by sharp turns and large speed changes of the diesel engine. Changes will cause inertial flow, and the lubricating oil will flow to the inclined side as the diesel engine tilts; When the inertial flow is large or the inclination angle is large, a large amount of lubricating oil in the oil pan will flow to one side or one end, causing the oil suction port of the oil suction pipe to expose the oil surface, and the oil pump will not be able to absorb lubricating oil normally. The way of pressure lubrication, at this time, the pressure of the lubrication system will suddenly drop, so that the part of the diesel engine that needs to be lubricated cannot be lubricated normally when it is tilted. Too low alarm shutdown, sudden shutdown affects the normal operation of the equipment, if the diesel engine without pressure alarm works in a state of poor lubrication, it may bring more serious consequences to the high-speed diesel engine
