Internal transportation machinery flow division device

Abstract

The invention relates to the mechanical design technical field, particularly to an internal transportation machinery flow division device. The internal transportation machinery flow division device comprises control chambers, a valve body, a filling body, a fixing body, penetrating pipes, a spring, a rotating block, a rotating plate, a connecting plate, a rotating shaft and a connecting pipe; the lower section of the valve body is in a conical shape; the middle section of the valve body is provided with four ribs; the upper section of the valve body is provided with external threads; the first penetrating pipe and he second penetrating pipe are arranged on the fixing body; the area of the cross section of the first penetrating pipe is smaller than that of the cross section of the second penetrating pipe; one end of the connecting pipe is communicated with an internal chamber body of the second control chamber; the other end of the connecting pipe is communicated with an intake pipe of an engine. When the pressure in the intake pipe of the engine is high, the valve body moves upward, a main oil channel and an oil return pipe are partitioned, and the pressure of the engine oil of the main oil channel is increased. When the pressure in the intake pipe of the engine is low, the valve body moves downward, the main oil channel is communicated with the oil return pipe, and the pressure of the engine oil of the main oil channel is reduced. The internal transportation machinery flow division device is reasonable in design, simple in structure and suitable for the optimized design of mechanical lubrication systems.

Description

technical field [0001] The invention relates to a lubricating adjustment system in the technical field of mechanical design, in particular to an internal shunting device for traffic machinery suitable for supercharged engines. Background technique [0002] When the engine is working, the speed is very high, and the parts between the piston and the cylinder wall, between the connecting rod bearing bush and the crankshaft are tightly matched. If these matching parts are not fully lubricated, dry friction will occur. The heat generated by dry friction in a short period of time is enough to melt the metal, causing damage or even jamming of the parts (piston scuffing, crankshaft pads, etc.), so the matching parts in the engine must be well lubricated. When the lubricating oil flows to the mating part, an oil film will be formed on the friction surface. In order to ensure that the lubricating oil can reach the mating surface smoothly, the engine lubricating oil must have a certai...
