Problems solved by technology

The patent adopts a variable capacity pump with a linear actuator, which can deliver any required capacity and can be automatically filled, avoiding the disadvantages of traditional quantitative pumps that have high brake noise and cannot flexibly control the additive capacity
However, this patent needs to use a professional linear actuator to control the stop of the metering pump, which has a complicated structure and high manufacturing cost. Moreover, during use, the piston of the metering pump is driven by a stepping motor and a gear reduction device. Moving, the linear brake is driven by a rotary electric motor through a gear reduction device. The entire pump body needs to add a motor and a gear reduction device, which not only increases the complexity of assembly, but also increases the difficulty of maintenance. Once the motor or reduction device fails , will cause the pump body to be unusable

Embodiment Construction

[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0026] Such as Figure 1 to Figure 8 As shown, this embodiment is a gasoline fine pump capable of pouring fuel additives into the gasoline tank, through which the gasoline in the gasoline tank can be purified, thereby improving the performance of the fuel.

[0027] The gasoline fine pump of this embodiment includes a casing 1 and an end cover 2, the casing 1 houses a pump assembly, the end cover 2 is detachably connected to the casing 1, and the end cover 2 adopts an anti-theft structure, which includes There is a cover body 21 and a connecting ring 22 arranged along the edge of the cover body 21. The lower end of the cover body 21 is formed with external threads, and the inner cavity of the shell 1 is provided with internal threads. The cover body 21 and the shell 1 are threadedly connected, and the connecting ring 22 and the edge of the cov...

Abstract

The invention provides a gasahol pump which comprises a valve jacket, an end cover and a suction pipe, and is characterized in that a pump assembly consists of a ferrule, an inner inserted link, a spring and a button switch, wherein the suction pipe is connected at the bottom of the ferrule, and the inner inserted link is inserted in the ferrule; the ferrule is provided with a spacer arranged in the direction of a cross section, the spacer is provided with an axial through channel, the bottom end of the inner inserted link is adaptive to the channel in shape and can seal the channel; the button switch is matched with the inner inserted link and can drive the bottom end of the inner inserted link to leave away the channel, the spring is sheathed on the inner inserted link, and the spring has a trend for leading a first oblique surface and a second oblique surface to be supported tightly at all the time and the bottom end of the inner inserted link to seal the channel. The gasahol pump can be used for effectively controlling the opening size of the ferrule channel and can apply force easily by adopting horizontal pushing mode for operation; and in use process, the opening or closing of the ferrule channel can be realized through the mobile contact of the first oblique surface and the second oblique surface, wear caused by extrusion and deformation can be effectively reduced, and the service life can be prolonged.

Description

technical field [0001] The invention relates to a device for fuel additives, in particular to a gasoline fine pump for improving the fuel purity of automobile fuel tanks. Background technique [0002] The popularity of automobiles as a means of transportation has entered the daily lives of more and more ordinary people. However, most people just use cars and hope that car maintenance can be foolish, which puts forward higher requirements on the economical fuel economy, emission standards and maintenance-free properties of cars. Studies have shown that adding appropriate additives to automobile fuel (domestic cars are mainly gasoline) can effectively improve the performance of the fuel and increase the combustion speed of the fuel to an appropriate range. Because after the fuel additive is added to the gasoline, it can form a protective layer on the surface of the intake system of the intake valve to prevent a large amount of deposits inside the engine, especially in the int...
