Description
Technical field
The present invention relates to the device that a kind of fuel additive is used, particularly a kind of for improving the gasoline sperm pump of fuel oil purity of automotive oil tank.
Background technique
Automobile is universal as the traffic tool, has entered into more and more ordinary peoples' daily life.But most people just uses automobile, wish that car maintaining can be fool, this has just proposed requirements at the higher level in the aspect such as the economic fuel-economizing to automobile, emission standard and non-maintaining property.Research shows, in vehicle fuel, (family-sized car is mainly gasoline) adds suitable additive, can effectively improve the performance of fuel oil, and makes the velocity of combustion of fuel oil bring up to suitable scope.Because after fuel oil additive is added in gasoline; can form layer protective layer on the gas handling system surface of suction valve; prevent that engine interior from especially producing a large amount of sedimentss in gas handling system; make the motor of automobile in whole using process, keep clean; and, use the gasoline that has added detergent additives can also realize fuel-efficient object concerning car owner.
At present, fuel oil additive generally all adopts common container to hold, when use, directly the lid of container is opened and toppled over, when this container is regained after toppling over or toppling over, the additive in container can be trickled down out because of the inclination of container, cause waste, and common container does not have quantitative function in the time toppling over yet, cannot control well the amount of fuel oil additive.
In order effectively to control the pouring volume of fuel oil additive, to ensure the quality of fuel oil, in prior art, a kind of pump body structure so the existing Chinese invention patent " for the metering pump of liquid fuel additive " that is ZL200480025298.6 as the patent No. discloses, this metering pump is a kind of metering pump of liquid additive of the fuel oil for heavy oil engine, described pump comprises: a piston, cylinder body and one move axially the actuator of this piston in cylinder body, and described actuator is a kind of high-precision linear actuators.In this patent, adopt the variable-displacement pump with linear actuators, can carry the capacity of any needs, and can automatic filling, avoided traditional metering pump brake noise large and cannot control flexibly the shortcoming of additive volume.But, in this patent, need to control with professional linear actuators the stop of metering pump, structure is comparatively complicated, manufacture cost is high, and, in use, the piston of metering pump is to move by means of stepper motor and gear reducer, linear brake is to be driven by gear reducer by a rotary electric motor, in the whole pump housing, need to set up motor and gear reducer, not only increased the complexity of assembling, also improved the difficulty of maintenance, once motor or speed reducer break down, will cause the pump housing to use.
Summary of the invention
Technical problem to be solved by this invention be provide for above-mentioned prior art present situation a kind of simple in structure, use gasoline sperm pump more convenient to operate.
The present invention solves the problems of the technologies described above adopted technological scheme: a kind of gasoline sperm pump, includes
