Description
Technical field
The present invention relates to a kind of variable-displacement pumps.
Background technique
Usually there are two types of mounting means, one kind is mounted in engine sump tank lubricating oil pump, by crankshaft by chain or
Belt driving, another kind are mounted in engine end and cover, directly driven by crankshaft.Lubricating oil pump working speed usually 500~
Within the scope of 6500rpm, the high revolving speed having is up to 8500rpm~10000rpm, and working oil temperature is between -30~150 DEG C, usually
At 95 DEG C.
The structure of existing vane type lubricating oil pump is as shown in Figure 1, it is mainly by the pump housing 91, rotor 92, blade 93, support ring
94, rotating dog 95, sliding block 96, sliding block spring 97, rectangular seal bar 98, rubber bar 99 etc. form, and there are following for the structure
The deficiency of aspect:
1, existing vane pump needs to guarantee blade and cunning in structure due to needing to guarantee high temperature idling performance and self-priming performance
Block inner wall is adjacent to, so needing to place two support rings in two ends of rotor, guarantees the gap of blade tip and sliding block inner wall.Simultaneously
Two ends of rotor needs to design support slot, which will lead to that rotor end sealing effect is bad and rotor strength reduces, and should
Structure increases rotor diameter, causes linear velocity excessive, so that the failure risk of cavitation cavitation erosion occurs, it is especially direct in crankshaft
The product disadvantage of driving is more prominent；
2, existing vane pump is that blade stretches in rotor vane groove, and blade and sliding block inner circle are slided, when revolving speed is increased to
When 3500rpm or more, the high-speed slide of blade and sliding block inner wall will cause can not form oil film between the two, cause abnormal
Ripple wear-out failure leads to the decline of blade pump volumetric efficiency, and the consumption of frictional work causes gross efficiency low, and noise is abnormal, seriously
The risk that will lead to safety and reliability, this is the most important defect of existing vane pump, and 6000rpm or more high speed work
It is restricted；
3, existing vane type variable-displacement pump, since blade needs to stretch in blade groove, so that the blade groove of root of blade
Occupied space and effect cavity cannot be formed with, space utilization rate is low, and the volume of pump and the ratio of pumpage are low, is unable to satisfy light weight
The rigors changed and minimized；Blade linear velocity can be very high simultaneously, and as revolving speed improves under the action of the centrifugal force, snout cavity turns
It can not be fully populated with oil liquid at sub- outer diameter, will lead to generation cavitation problem；Vane pump is inefficient, while cavitation erosion makes rotor and leaf
Piece vibration, they strike sliding block cause to fail, and especially drive in crankshaft straight more serious on product.
As energy conservation and environmental protection and emission regulation demands are increasingly stringenter and the shortage of petroleum resources, need in the market
The shortcoming that existing vane type becomes displacement oil pump structure is improved and is innovated, to meet the following more harsh discharge
Regulation and the market demand.
