Abstract
The utility model relates to an engine lubricating system, more specifically an engine oil conveying system of an engine. The utility model is composed of a crankcase oil tray, an engine oil pump, an engine oil pipe passage, an engine oil passage and a pressure regulating valve, wherein the pressure regulating valve is arranged on an engine oil coarse filter and the pressure regulating valve is not arranged on a main oil passage. When the engine works, the pressure of the main oil passage controlled by the system is smaller than 0.6 MPa, and desired engine oil amounts are guaranteed to convey to positions needing lubricating, such as a crank main journal, etc. The utility model has the advantage of simple structure. Because the pressure regulating valve is not arranged on the main oil passage, the utility model avoids phenomena of the deficient oil supply and the bad lubrication of the positions needing lubricating, such as the crank main journal, etc., from occurring caused by that partial engine oil directly flows back to the crankcase oil tray from the pressure regulating valve of the main oil passage in the process of using.
Description
Technical field
The utility model relates to a kind of engine lubrication system, a kind of engine motor oil transporting system of more specifically saying so.
Background technique
The engine motor oil transporting system comprises oil sump, oil pump, machine oil pipeline, machine oil oil duct and pressure regulator valve at present.The YC6105QC and the YC6108Q diesel engine of the tonnage diesel engine for automobile configuration of current China, be provided with two pressure regulator valves in its oil delivery system: be located at pressure regulator valve on the primary oil filter and the pressure regulator valve on the main oil gallery, common control main oil gallery pressure＜0.6MPa, from design, the pressure regulator valve genus is set on the main oil gallery of primary oil filter pressure regulator valve rear end again to be repeated to be provided with, also often occurring the main oil gallery engine oil pressure in actual the use shows normal, part machine oil then directly flows back to oil sump from the main oil gallery pressure regulator valve of opening, cause need lubricant housings fuel feeding deficiencies such as crankshaft main journal, insufficient lubrication, and then the bent axle tile kilning takes place, motor is scrapped phenomenon.
Summary of the invention
The purpose of this utility model provides a kind of engine motor oil transporting system, owing on its main oil gallery pressure regulator valve is not set, avoided that part machine oil directly flows back to oil sump from the main oil gallery pressure regulator valve in the using process, make crankshaft main journal etc. need lubricant housings fuel feeding deficiency, insufficient lubrication, so that bent axle tile kilning, motor are scrapped the generation of phenomenon.
For achieving the above object, solution of the present utility model is: in the oil delivery system that is made up of oil sump, oil pump, machine oil pipeline, machine oil oil duct and pressure regulator valve, pressure regulator valve is located on the primary oil filter, and pressure regulator valve is not set on the main oil gallery.During engine operation, the control main oil gallery pressure＜0.6MPa of this system, the oil level arrival crankshaft main journal that the guarantee conveying is required etc. needs the lubricant housings.
The beneficial effects of the utility model are simple in structure, can avoid crankshaft main journal etc. to need lubricant housings fuel feeding deficiency, insufficient lubrication, so that bent axle tile kilning, motor are scrapped the generation of phenomenon.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is an oil delivery system schematic of the present utility model.
Fig. 2 is oil delivery system line figure of the present utility model.
1-sump strainer among the figure, 2-oil pump, the centrifugal filter thin oil pressure regulator valve of 3-, the centrifugal filter thin oil of 4-, the 5-air compressor, 6-idle gear, 7-main oil gallery, 8-primary oil filter bypass valve, the 9-oil pressure is crossed low alarm, 10-fuel level indicator, 11-primary oil filter, 12-primary oil filter pressure regulator valve, the 13-oil sump.
Embodiment
The oil delivery system that the utility model is made up of oil sump (13), oil pump (2), machine oil pipeline, machine oil oil duct and pressure regulator valve (12), pressure regulator valve (12) is located on the primary oil filter (11), and its main oil gallery is not provided with pressure regulator valve on (7).During engine operation, control main oil gallery (7) pressure＜0.6MPa of this system, the oil level arrival crankshaft main journal that the guarantee conveying is required etc. needs the lubricant housings.
