Abstract
An engine oil pump comprises an oil pump body provided with a rotor chamber and a rotor shaft mounting hole. The engine oil pump is characterized in that a sedimentation groove is disposed at the bottom of the rotor chamber, a residue discharge groove is arranged at the bottom of the sedimentation groove, and a residue storage groove which is communicated with the residue discharge groove is arranged on the wall of the rotor shaft mounting hole. The oil pump is favorable for reducing friction loss of an engine, reduces abnormal abrasion of a rotor of the oil pump and blockage of the rotor due to the fact that impurities enter the rotor chamber along with oil, accordingly reduces probability of scuffing of a cylinder bore, further improves economic efficiency and reliability of the engine and is simple in structure and high in practicality.
Description
Technical field
The utility model belongs to the component of internal-combustion engine, relates to a kind of engine oil pump, is the improvement of prior art.Be particularly suitable for the low pollution of high speed, Europe III emission standard, the employing of low fuel oil consumption vehicular engine.
Background technique
In the prior art, engine oil pump mainly is made up of oil pump body, inside and outside rotor in oil pump, oil pump transmission shaft, oil pump adjusting pressuring valve core, oil pump pressure regulator valve spring, oil pump pressure regulation valve pad and plug screw, oil pump driving wheel and connecting bolt etc.; Rotor chamber and rotor shaft mounting hole are arranged on the oil pump body, and in the use, impurity easily enters rotor chamber with machine oil, causes rotor of engine oil pump inordinate wear and rotor stuck, thereby scuffing of cylinder bore occurs, influences the reliability of motor.
Along with the highway in China transportation is hanged down the pollutionization development towards high speed, economic, comfortable reaching, and the deflation day by day of national energy policy, for satisfying the fuel limit rules of all kinds of light buses, light duty cross-country car, light-duty notchback, light truck, Economy to motor is had higher requirement, realize that these requirements will carry out architecture advances to oil pump class important spare part, to satisfy the engine performance requirement.
Summary of the invention
The purpose of this utility model is intended to overcome deficiency of the prior art, and a kind of engine oil pump of simple in structure, superior performance is provided.Be specially adapted to use in the low pollution of high speed, Europe III emission standard, the low fuel oil consumption vehicular engine.
Content of the present utility model is: a kind of engine oil pump comprises: the oil pump body of rotor chamber and rotor shaft mounting hole is arranged, it is characterized in that: the bottom of described rotor chamber (2) is provided with subsing tank (4).
In the content of the present utility model: the bottom of described subsing tank (4) also is provided with deslagging groove (5).
In the content of the present utility model: also have a storage slag chute (6) that is connected with described deslagging groove (5) on the hole wall of described rotor shaft mounting hole (3).
Compared with prior art, the utlity model has following characteristics and beneficial effect:
(1) oil pump that adopts the utility model to provide, the motor that can be high temperature, high load and high-speed motion provides necessary lubricant oil, help reducing the friction loss of motor, minimizing enters rotor chamber because of impurity with machine oil, cause rotor of engine oil pump inordinate wear and rotor stuck, thereby reduce the scuffing of cylinder bore probability, further improve the Economy and the reliability of motor;
(2) simple in structure, cost is low, makes easily, is mainly used in the mating power of light duty cross-country car, light bus, light truck and light-duty notchback, can satisfy the needs of the low pollution of Europe III emission standard, low fuel oil consumption petrol engine etc., practical.
Description of drawings
Fig. 1 is the utility model embodiment oil pump body structural representation;
Fig. 2 is the A-A sectional structure schematic representation of Fig. 1.
Among the figure: 1-oil pump body, 2-rotor chamber, 3-rotor shaft mounting hole, 4-subsing tank, 5-deslagging groove, 6-store up slag chute.
Embodiment
The utility model is described in further detail by embodiment below in conjunction with accompanying drawing.
Embodiment 1: referring to each accompanying drawing.
A kind of engine oil pump includes the oil pump body 1 of rotor chamber 2 and rotor shaft mounting hole 3, and the bottom of this rotor chamber 2 is provided with subsing tank 4; The bottom of subsing tank 4 is provided with deslagging groove 5; A storage slag chute 6 that is connected with described deslagging groove 5 is arranged on the hole wall of rotor shaft mounting hole 3.
Other composition of this engine oil pump, comprise: oil pump body, inside and outside rotor in oil pump, oil pump transmission shaft, oil pump adjusting pressuring valve core, oil pump pressure regulator valve spring, oil pump pressure regulation valve pad and plug screw, oil pump driving wheel and bolt etc., same prior art.
Engine oil pump in use, when inside and outside rotor in oil pump is brought small amount of impurities in rotary course after, impurity gets rid of under action of centrifugal force into subsing tank 4, impurity level more for a long time, the storage slag chute 6 that impurity enters deslagging groove 5 and is connected with deslagging groove 5, thus rotor inordinate wear and stuck effectively prevented.
The utility model is not limited to the foregoing description, and the utility model content is described all can implement and have described good result.
Claims (3)
1. engine oil pump, comprising: the oil pump body of rotor chamber and rotor shaft mounting hole is arranged, it is characterized in that: the bottom of described rotor chamber (2) is provided with subsing tank (4).
2. by the described engine oil pump of claim 1, it is characterized in that: the bottom of described subsing tank (4) is provided with deslagging groove (5).
