Abstract
The utility model discloses a booster oil pump of a diesel engine to solve the potential safety hazard caused by the booster oil pump of the conventional diesel engine without pressure regulating system. The booster oil pump of the diesel engine comprises a gear, a pressure relief system, a supercharging cover, a middle cover, a large cam, a small cam, a copper sleeve, a spline and an axis, wherein the pressure relief system is formed by a pressure regulating screw, a spring, and a steel ball and installed in the pressure regulating hole of the supercharging cover. The pressure is regulated by the pressure regulating screw of the pressure relief system to improve the safety performance, when the negative pressure is much high.
Description
One, technical field
The utility model relates to a kind of oil pump, particularly relates to a kind of pressure-increasing machine oil pump.
Two, background technique
At present especially existing oil pump is not owing to there is decompressor in the lubricating system of diesel oil engine for internal-combustion engine system, and Safety performance can not get guaranteeing when negative pressure is higher, must develop novel oil pump and could satisfy customer requirements.
Three, model utility content
The purpose of this utility model is the new oil pump that will provide a kind of Safety performance higher, to substitute oil pump on the existing diesel, overcomes the purpose of its poor safety performance.The pressure-increasing machine oil pump can adopt following technological scheme to implement on this diesel engine: it is made up of gear, depressurized system, supercharging lid, middle cover, big cam, little cam, copper sheathing, spline, axle, wherein depressurized system is formed and is installed in the regulator hole that supercharging covers by pressure regulating screw, spring, steel ball, spring housing is on pressure regulating screw, steel ball places the top of pressure regulating screw, and pressure regulating screw is fixed on supercharging by nut and covers.All the other structures and mutual installation connection are identical with oil pump on the existing diesel.
The pressure-increasing machine oil pump is compared its major advantage with oil pump on the existing diesel and is on the diesel engine that designs and produces according to technique scheme: after increasing depressurized system, when negative pressure is higher, can regulate pressure by the pressure regulating screw in the depressurized system, improve Safety performance, and this mechanical type voltage-regulating system is simple in structure, stable and reliable for performance.
Four, description of drawings
Pressure-increasing machine oil pump structure schematic representation on Fig. 1, the diesel engine.
Five, embodiment
The utility model will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, the pressure-increasing machine oil pump is made up of gear 1, depressurized system, supercharging lid 4, middle cover 7, big cam 8, little cam 9, copper sheathing 10 and copper sheathing 13, spline 11, axle 12 on the diesel engine, wherein depressurized system is made up of pressure regulating screw 2, spring 5, steel ball 6 and is installed in the regulator hole on the supercharging lid 4, spring 5 is enclosed within on the pressure regulating screw 2, steel ball 6 places the top of pressure regulating screw 2, and pressure regulating screw 2 is fixed on supercharging by nut 3 and covers.All the other structures and mutual installation connection are installed on the axle 12 as gear 1, big cam 8, little cam 9, spline 11, axle is placed in the axis hole on supercharging lid 4 and the middle cover 7, and it is all identical with oil pump on the existing diesel with copper sheathing 13 grades that copper sheathing 10 is housed at the two ends of axle.This novel pressure-increasing machine oil pump can be regulated pressure by the pressure regulating screw in the depressurized system when negative pressure is higher, improve Safety performance.
