Description
Technical field
The utility model relates to engine oil pump pressure-limiting valve technical field, is specifically related to a kind of engine oil pump pressure-limiting valve anti-blockage structure.
Background technique
The core component of the lubrication system of motor is oil pump, and the lubricating function of whole motor is all realized by oil pump.Once the oil pump of motor goes wrong, what so directly cause is exactly that engine lubrication is inadequate, and the component such as connecting rod, bent axle, camshaft, cylinder all wear and tear, and engine power moment of torsion is all abnormal, until motor is scrapped.
The machine oil of motor is after fuel filter (coarse filtration) just in direct ingress engine oil pump, machine oil now also has in partial impurities (such as aluminium bits impurity) meeting ingress engine oil pump, the degree of purity of organic oil guarantee machine oil after the oil filter (essence filter) of oil pump is filtered.
If once have in the pressure-limit valve of impurity ingress engine oil pump, in pressure-limit valve back and forth working procedure, impurity will enter in the gap between the plunger of pressure-limit valve and pump housing wall, thus cause plunger to be blocked by pump housing wall, cause pressure-limit valve no longer to work, thus cause a large amount of machine oil to be revealed from pressure-limit valve, only have a small amount of machine oil to enter in motor, make engine lubrication not enough, thus produce a series of serious consequence damaging motor.
Pressure-limit valve due to existing this pump housing of oil pump is all cylinder piston, so the way that the pressure-limit valve of Ge great main engine factory to this pump housing of oil pump is taked at present increases groove on cylinder piston.But this way increasing groove at present on the cylinder piston of pressure-limit valve fundamentally can not solve the blocking risk between the cylinder piston of pressure-limit valve and pump housing wall, part aluminium still can be had to consider impurity to be worth doing and to be blocked between cylinder piston and pump housing wall and to be difficult to get rid of.Therefore, design and a kind ofly can effectively stop most of impurity to enter in the valve pocket of pressure-limit valve from source, and not easily occur that impurity is blocked between spheroid piston and pump housing wall, structure be simple, good airproof performance, engine oil pump pressure-limiting valve anti-blockage structure easy to maintenance seems very necessary.
Model utility content
The utility model is the pressure-limit valve in order to solve existing this pump housing of oil pump is all cylinder piston, easily block between the cylinder piston of pressure-limit valve and pump housing wall, and be difficult to the deficiency of eliminating, thering is provided a kind of can effectively stop most of impurity to enter in the valve pocket of pressure-limit valve from source, and not easily occur that impurity is blocked between spheroid piston and pump housing wall, structure is simple, good airproof performance, a kind of engine oil pump pressure-limiting valve anti-blockage structure easy to maintenance.
Above technical problem is solved by following technical proposal:
A kind of engine oil pump pressure-limiting valve anti-blockage structure, comprise this pump housing of oil pump, also comprise the filter screen that can filter out machine well cuts, the rim seal of filter screen is connected on the filler opening upper edge of the pressure-limit valve of this pump housing of oil pump; In the valve pocket of pressure-limit valve from outer end to inner end successively respectively activity be placed with a spring, spheroid piston, No. two springs and No. two spheroid pistons; Tighten Guan County in the external port of described valve pocket and plug screw is housed, and the two ends of a spring compress respectively and to be connected on a spheroid piston and on plug screw, the two ends of No. two springs compress respectively and are connected on a spheroid piston and on No. two spheroid pistons.
During use, enter into this pump housing of oil pump containing more polymictic machine oil from inlet port.A part does not have the machine oil diameter of net filtration after filtration to export from oil outlet, the larger impurity of most diameter in another part machine oil is owing to being subject to the prevention of filter screen, make the larger impurity of the most diameter in machine oil can not enter into the valve pocket of pressure-limit valve, thus from source, effectively prevent most of impurity to enter in the valve pocket of pressure-limit valve, and then decrease impurity and be blocked in probability between spheroid piston and pump housing wall, the area of contact of spheroid piston and pump housing wall is few, the impurity be accumulated between spheroid piston and pump housing wall also can lack, so the probability that impurity is blocked between spheroid piston and pump housing wall is lower.The machine oil entered in the valve pocket of pressure-limit valve enters into this pump housing of oil pump from inlet port from drain tap again through return tube.This programme can effectively stop most of impurity to enter in the valve pocket of pressure-limit valve from source; and not easily occur that impurity is blocked between spheroid piston and pump housing wall; reduce the blocking risk between the plunger of pressure-limit valve and pump housing wall, thus the function of available protecting oil pump.This programme is by the cooperation of a spring, spheroid piston, No. two springs and No. two spheroid pistons, and make adjustability and seal better, structure is simple, and maintenance also more for convenience.
As preferably, described valve pocket is followed successively by thread section chamber, piston glissile segment chamber and anti-collision section chamber from outer end to inner end, and the diameter in thread section chamber is greater than the diameter in piston glissile segment chamber, the diameter in piston glissile segment chamber is greater than the diameter in anti-collision section chamber, and described drain tap is arranged on the inwall in piston glissile segment chamber.
This sealing structure is good, the Various Functions of every section, and such as, thread section chamber is that plug screw is fixed used, and piston glissile segment chamber is that a spring, spheroid piston, No. two springs and No. two spheroid pistons are used, and anti-collision section chamber is that strainer filtering is used.Such a construction ensures seal and the reliability of valve pocket.
As preferably, the joint in piston glissile segment chamber and anti-collision section chamber is the arc-shaped curved surface matched with the spherical outer surface of described No. two spheroid pistons.Because No. two spheroid pistons need back and forth the reciprocal joint impinging upon piston glissile segment chamber and anti-collision section chamber, the outer surface that such a construction ensures No. two spheroid pistons is not easily damaged.
As preferably, described filter screen has at least two-layer.This structured filter is effective.
As preferably, a spheroid piston is identical with the size of No. two spheroid pistons, and the elasticity of a spring is greater than the elasticity of No. two springs.
As preferably, the diameter being arranged in the drain tap of this pump housing of oil pump on valve pocket inwall is less than the diameter of No. two spheroid pistons.
The utility model can reach following effect:
The utility model can effectively stop most of impurity to enter in the valve pocket of pressure-limit valve from source; and not easily occur that impurity is blocked between spheroid piston and pump housing wall; reduce the blocking risk between the plunger of pressure-limit valve and pump housing wall; thus the function of available protecting oil pump; structure is simple; good airproof performance, easy to maintenance.
