Abstract
The utility model discloses a machine oil pump, more particularly to a leakage proof machine oil pump, which is composed of a pump cover, a pump body, an internal rotor, an external rotor, a paper pad and a positioning pin. Wherein, the edges of the pump cover and the pump body is drilled with a leakage proof hole that is positioned at the outer positions of a flange disc, an oil charging and discharging groove and the positioning pin; and the inside part of the leakage proof hole is connected with a screw. Through fastening the pump cover and the pump body by the screw, the sealing performance of the machine oil pump is greatly improved. In the same working environment, the machine oil pump can support one more to two more oil pressures than the original machine oil pumps, and the quality and stability of the machine oil pump are greatly improved, basically disposing the problem of oil leaking while prolonging the application lifetime. Through adopting the new technology, the plane polishing and oil pulling back to the tank these work procedures during the process of machine oil pump processing is reduced, and thus the utility model has the advantages of simple structure, convenient processing, higher efficiency, lower labor intensity of the workers and with unexpected effect.
Description
Technical field the utility model relates to a kind of diesel engine oil pump, a kind of specifically leakage proof oil pump.
Background technique
At present, the oil pump that people use is that a macropore is arranged in the pump housing, internal rotor and external rotor are packed in the macropore of the pump housing, two confessions that are " splayed shape " are arranged in pump cover, go out oil groove, the flange hole and the positioning pin hole that run through are arranged on the edge of the pump cover and the pump housing, between the pump cover and the pump housing, paper washer is arranged, the pump cover and the pump housing are fixed by locating stud.Oil pump rising and diesel engine with oil pressure in the fuel feeding process worked on rough work-yard, because the pump cover and the pump housing only adopt the fixing pump cover that can cause of locating stud to take place to become flexible, slit between the pump cover and the pump housing is strengthened, thereby the situation that seepage machine oil occurs, cause to break away from serious consequences such as working position, oil pump cover come off, cause machine breakdown internal rotor and external rotor further then not occurring.
Summary of the invention
To be solved in the utility model be exactly present diesel engine oil pump in use, easy seepage machine oil, internal rotor and external rotor break away from the problem that working position, oil pump cover come off.
Solve the technological scheme that its technical problem adopts: on the edge of the pump cover and the pump housing, bore the antiseepage small opening, the position that the antiseepage small opening is positioned at flange hole, confession, goes out oil groove, positioning pin hole is outer, connecting screw is followed closely in the antiseepage small opening.
The quantity of antiseepage small opening is three, and screw is M5 * 20 hexagon socket head cap screws nail.
Beneficial effect: the utility model increases the antiseepage small opening at the edge of the pump cover and the pump housing, connecting screw nail in the antiseepage small opening, by screw the pressurization fixedly pump cover and the pump housing, the sealability of oil pump is improved greatly, the comparable original oil pump of this oil pump is born 1-2 oil pressure more in identical working environment, and the quality of oil pump and stability are improved largely, fundamentally solved the problem of seepage oil, prolong working life, use the flat surface grinding in the time of to save original processing machine oil pump after the utility model scheme, retract operations such as oil groove, simple in structure, easy to process, improve efficient, reduced working strength of workers, produced beyond thought effect.

Embodiment
Embodiment 1: connect internal rotor 11 and external rotor 10 in the macropore of the oil pump pump housing 8, two confessions that are " splayed shape " are arranged in pump cover 1, go out oil groove, the flange hole 12 and the positioning pin hole 3 that run through are arranged on the edge of the pump cover 1 and the pump housing 8, between the pump cover 1 and the pump housing 8, paper washer 5 is arranged, by locating stud 7 that the pump cover 1 and the pump housing 8 is fixing, on the edge of the pump cover 1 and the pump housing 8, bore antiseepage small opening 2, the position that antiseepage small opening 2 is positioned at flange hole 12, confession, goes out oil groove, positioning pin hole 3 is outer, connecting screw follows closely 6 antiseepage small opening 2 in.Gently rotate pump shaft with have gentle hands and should rotate no catching phenomenon flexibly, be pressed into 2 locating studs 7 in positioning pin hole 3, antiseepage small opening 2 is the sunk screw hole of 3 * φ 9, buys back afterloading unit for the user and uses.Bore 3 * φ, 5.5 sunk screw holes, (3 * φ 9 is a pump cover part, and 3 * φ 5.5 is a pump cover part and a pump housing part), last tapping machine is attacked 3 * M5 screw hole, puts into spring sheet earlier in three φ 5.5 holes, puts into M5 * 20 screws again, and tightens.
Embodiment 2: according to circumstances, can reinforce screw dissimilar, quantity on different oil pump such as S1105, S1110, S1115.
Claims (2)
1, a kind of leakage proof oil pump, by pump cover, the pump housing, internal rotor, external rotor, paper washer, locating stud is formed, pump is that a macropore is arranged in the pump housing, internal rotor and external rotor are packed in the macropore of the pump housing, two confessions that are " splayed shape " are arranged in pump cover, go out oil groove, the flange hole and the positioning pin hole that run through are arranged on the edge of the pump cover and the pump housing, between the pump cover and the pump housing, paper washer is arranged, be connected with locating stud on the pump cover and the pump housing, it is characterized in that: on the edge of the pump cover and the pump housing, be drilled with the antiseepage small opening, the antiseepage small opening is positioned at flange hole, supply, go out oil groove, the position that positioning pin hole is outer, connecting screw nail in the antiseepage small opening.
