Description

The oil pump that a kind of sealing is strong

Technical field

The present invention relates to a kind of oil pump, the oil pump that especially a kind of sealing is strong.

Background technique

The effect of oil pump in lubrication system: oil pump effect is after machine oil is brought up to certain pressure, be sent on the moving surface of each part of motor forcibly, fuel pump structure form can be divided into gear type and rotator type two class, gear type oil pump is divided into again internal-gear type and external gear formula, generally the latter is called gear-type oil pump, but the sealing of traditional oil pump is not ideal enough, even can cause the accident that leakage of oil etc. is great, thus normal use is impacted.

Summary of the invention

The object of the present invention is to provide the oil pump that a kind of sealing is strong, to solve the problem proposed in above-mentioned background technology.

The object of the invention is to be achieved by following technical proposals: the oil pump that a kind of sealing is strong, comprise cog, pin, pump cover, lower gear, fixed base, sump, running shaft, oil inlet hole, the pump housing and attachment hole, described in cog and be arranged on the inside of the pump housing; The described below cogged is provided with lower gear; Described pump cover is arranged on the side of the pump housing; Described fixed base is arranged on the bottom of the pump housing; Described fixed base is provided with attachment hole; Described sump is arranged on the inside of the pump housing; Described cogging connects on the rotary shaft; The side of the described pump housing is provided with oil inlet hole; Described cogging is arranged in sump with lower gear; The described pump housing is provided with pin.

Further, described oil inlet hole is provided with seal ring.

Further, cog described in and lower gear carry out connection of rotating by gear.

Further, described attachment hole adopts hexagonal configuration.

Further, the described pump housing adopts Wear resistant anti-high pressure metal to make.

Compared with prior art, the invention has the beneficial effects as follows the oil pump that this kind of sealing is strong, easy to use, the effect of sealing is strong, simultaneously low cost, long service life and quality is light and handy, is applicable to promoting the use of.
