Specific embodiment
For a clearer understanding of the technical features, objectives and effects of the utility model, now compareing Detailed description of the invention
Specific embodiment of the present utility model.
A kind of high flow capacity impeller pump of embodiment 1
As shown in Figure 1, the utility model provides a kind of high flow capacity impeller pump, including pump housing oil outlet 1, bushing 2, lubricating oil pump
The pump housing 3, machine oil pump shaft 4, pump housing oil suction chamber 5, internal rotor 6, outer rotor 7, inlet port 8, oil pump cover oil suction chamber 9, oil pump cover
10, transmission gear 11, job key 12.
It is provided with machine oil pump shaft 4 in the lubricating oil pump pump housing 3 and 4 one end of machine oil pump shaft leans out the lubricating oil pump pump housing 3, the machine
Oil pump shaft 4 leans out one end connection transmission gear 11 of the lubricating oil pump pump housing 3.Bushing 2, the lining are provided on the machine oil pump shaft 4
Set 2 uses three-layer self lubricating abrasion-resistant axle sleeves, and three-layer self lubricating abrasion-resistant axle sleeve improves the resistance to of machine oil pump shaft 4 and the lubricating oil pump pump housing 3
Mill property, increases the service life of lubricating oil pump.
It is provided with pump housing oil suction chamber 5 in the lubricating oil pump pump housing 3, is provided in the pump housing oil suction chamber 5 intermeshing
Internal rotor 6 and outer rotor 7 are connected between the internal rotor 6 and machine oil pump shaft 4 by job key 12.
Oil pump cover 10 is provided on the lubricating oil pump pump housing 3, the oil pump cover 10 is groove structure, the groove knot
The oil pump cover 10 of structure is connected to form cargo tank with pump housing oil suction chamber 5, can be used for containing machine oil.
Inlet port 8 is provided on the lubricating oil pump pump housing 3, the inlet port 8 is connected to oil pump cover 10 and pump housing oil suction chamber 5
The cargo tank of formation allows two sides oil inlet of the machine oil entered by inlet port 8 from cargo tank, substantially increases oil inlet flow.
Pump housing oil outlet 1 is provided on the lubricating oil pump pump housing 3 and positioned at the opposite side of pump housing oil suction chamber 5.
Specifically, the high flow capacity impeller pump, including the pump housing, there is oil suction chamber on the pump housing, for traditional lubricating oil pump,
Machine oil enters directly into the oil suction chamber of the pump housing after inlet port sucking, and machine oil enters internal rotor by pump housing oil suction chamber, then by
Oil outlet is sent under the interaction of internal rotor and outer rotor, entire oil-absorbing process is completed by pump housing unilateral side, therefore flow by
Certain limitation；And the utility model patent then improves the structure of the pump housing, by the oil suction chamber of the pump housing and pump cover oil suction chamber
Connection completely, and all communicated with inlet port, as a result at work, during oil suction, sucking machine oil a part enters lubricating oil pump
To pump housing oil suction chamber, another part enters in pump cover oil suction chamber, and machine oil just shunts before entering internal rotor, from rotor
Two sides suck simultaneously, be equivalent to and oil suction area expanded one times, oil suction is more smooth, therefore oil pump capacity is mentioned
It is high.
When work, transmission gear 11 is driven by external force to be rotated, and drives internal rotor 6 with identical revolving speed by machine oil pump shaft 4
Rotation, internal rotor 6 and outer rotor 7 form several closed working chambers, and with the rotation of rotor 6, the volume of working chamber is in week
The variation of phase property.In the side cavity of oil inlet, since rotor is disengaged, volume is gradually increased, and generates vacuum, machine oil is by the pump housing
3 and the oil suction chamber of pump cover 10 be inhaled into the between cog of internal rotor 6 and outer rotor 7, as rotor continues to rotate, machine oil is brought to out
The side of oil duct, at this moment, rotor just enter engagement, reduce this cavity volume, and oil pressure increases, and machine oil squeezes out simultaneously between cog
It goes out through oil outlet force feed.In this way, machine oil is just constantly inhaled into and extrudes with the continuous rotation of rotor.
The utility model patent is compact-sized, and outer dimension is small, light-weight, and pump discharge is big, at low cost, in, large-scale hair
It is promoted and applied in motivation.
The characteristics of utility model：More channels, pump housing oil suction chamber is connected to pump cover oil suction chamber on oil pump body
Together, allow machine oil from two ends of rotor while sucking, before changing the drawbacks of unilateral sucking, increase oil suction area,
It is improved the flow of lubricating oil pump.
The above is the citing of the utility model preferred forms, wherein the part that do not address in detail is this field
The common knowledge of those of ordinary skill.The protection scope of the utility model is based on the contents of the claims, any to be based on this reality
The equivalent transformation carried out with novel technical inspiration, is also within the protection scope of the utility model.
