Abstract
The utility model relates to an oil strainer of an engine. A connection flange mounted on an oil pump is arranged at one end of an oil suction pipe of the strainer; a sealing ring and a flange bush are arranged on the connection flange; a strainer cover soaked in oil is arranged at the other end, and a filter screen is mounted on the strainer cover; a bracket fixed on an engine cylinder is arranged on the oil suction pipe close to the filter screen; and a bush is arranged on the bracket. The pipe diameter of the oil suction pipe from the bracket to the strainer cover section is smooth and continuously and gradually increased in a bell mouth shape; and the cross-sectional area of the oil suction pipe at the strainer cover is the maximum cross-sectional area, the cross-sectional area of the oil suction pipe at the connection flange is the minimum cross-sectional area, and the maximum cross-sectional area is 2-3 times the minimum cross-sectional area. The cross-sectional area at an oil suction port of the strainer cover is greater than the minimum cross-sectional area of the oil suction pipe. Through the utility model, the shortcoming that the effective filter area of the filter screen is not enough is overcome, and the problems of cavitation of the oil pump and the like are avoided.
Description
Technical field
The utility model belongs to technical field of internal combustion engines, is specifically related to a kind of sump strainer of motor.
Background technique
Sump strainer is to be arranged in the device that first road in the oil sump is used to filter machine oil impurity in the engine lubrication system.Existing plastics sump strainer mainly is made up of fuel sucking pipe, filter screen and fuel filter cover etc.The cross-section area of the fuel sucking pipe of above-mentioned existing plastics sump strainer all equates everywhere; The effective filtration area of filter screen must be littler than the cross-section area of fuel sucking pipe like this; Adding the part mesh might be blocked; Cause fuel feeding not enough, cause a series of problems such as oil pump cavitates, and engine oil pressure is low.
The model utility content
Cause problems such as oil pump cavitates, engine oil pressure is low in order to solve because of the filter screen effective filtration area is not enough, the reliability of assurance engine running, the utility model provides a kind of engine oil strainer that improves structure.
The technology of the utility model solves as follows:
A kind of engine oil strainer comprises fuel sucking pipe 4; One end of fuel sucking pipe 4 is provided for being installed in the adpting flange 4b on the oil pump; Adpting flange 4b is provided with seal ring 1 and lining A2; The other end is provided with one and is immersed in the fuel filter cover 6 in the machine oil and filter screen 5 is installed above that, and said fuel sucking pipe 4 is provided with near the position of filter screen 5 and is used for support 4a fixing on engine cylinder-body, and lining B3 is set on the support 4a; Said support 4a increases to the caliber smooth and continuous of the fuel sucking pipe 4 of 6 sections on said fuel filter cover gradually, is bell mouth shape; The cross-section area of said fuel filter cover 6 place's fuel sucking pipes 4 is the maximum cross-section areas, and the cross-section area of said adpting flange 4b place fuel sucking pipe 4 is smallest cross-section areas, and said the maximum cross-section area is 2～3 times of smallest cross-section area.
The cross-section area at the machine oil suction port 6a place of said fuel filter cover 6 is greater than the smallest cross-section area of fuel sucking pipe 4.
Said filter screen 5 is metal knitted net, and its percentage sieving area is not less than 58%.
The beneficial technical effects of the utility model is; Through improvement to fuel sucking pipe, fuel filter cover and filter screen cross section structure; The filter screen effective filtration area defect of insufficient of having avoided the uniform section structure of existing technology to cause, thus problem such as oil pump cavitation erosion avoided, even the part mesh stops up and also can guarantee the engine reliable running; And because the sectional area smooth and continuous of fuel sucking pipe changes, circulating resistance is little and filter efficiency is high.
Description of drawings
Fig. 1 is the utility model sump strainer structural representation.
Sequence number among the last figure: seal ring 1, lining A2, lining B3, fuel sucking pipe 4, support 4a, adpting flange 4b, filter screen 5, fuel filter cover 6, machine oil suction port 6a.
Embodiment
Below in conjunction with accompanying drawing, the embodiment of the utility model is described in detail, but the protection domain that is to be understood that the utility model does not receive the restriction of embodiment.
Embodiment:
Referring to Fig. 1; The sump strainer of motor comprises fuel sucking pipe 4; One end of fuel sucking pipe 4 is provided for being installed in the adpting flange 4b on the oil pump, and adpting flange 4b is provided with seal ring 1 and lining A2, and the other end is provided with one and is immersed in the fuel filter cover 6 in the machine oil and filter screen 5 is installed above that; Said fuel sucking pipe 4 is provided with near the position of filter screen 5 and is used for support 4a fixing on engine cylinder-body, and lining B3 is set on the support 4a.The caliber smooth and continuous of the fuel sucking pipe 4 from said support 4a to 6 sections on said fuel filter cover increases gradually, is bell mouth shape; The cross-section area of said fuel filter cover 6 place's fuel sucking pipes 4 is the maximum cross-section areas, and the cross-section area of said adpting flange 4b place fuel sucking pipe 4 is smallest cross-section areas, and said the maximum cross-section area is 2～3 times of smallest cross-section area.The cross-section area at the machine oil suction port 6a place of said fuel filter cover 6 is greater than the smallest cross-section area of fuel sucking pipe 4.Said filter screen 5 is metal knitted net, and its percentage sieving area is not less than 58%.
Picture is as shown in Figure 1, and said fuel sucking pipe 4, adpting flange 4b and support 4a are integrated injection molding, and material is PA66-GF30; Lining A2 and lining B3 press-fit respectively or are embedded in adpting flange 4b and the support 4a respective aperture, and material is 20 steel; Seal ring 1 is assemblied in the seal groove of adpting flange 4b.
As shown in Figure 2, said fuel filter cover 6 is molding and forming, and material is PA66-GF30, is provided with the face of weld of certain width at its periphery, so that firmly weld together with fuel sucking pipe 4, simultaneously filter screen 5 is fixed between the mating face.
During the motor proper functioning; Machine oil gets in the sump strainer from the mesh of filter screen 5; Impurity greater than mesh aperture then is filtered; Because the gross area of filter screen 5 mesh is far longer than the smallest cross-section area of fuel sucking pipe 4, and the variation of fuel sucking pipe 4 diameter smooth and continuous, so the circulating resistance of sump strainer is very little and can guarantee that fuel feeding is sufficient reliable.
