Abstract
The utility model discloses a gear pump suitable for fuel refueling machine. The utility model comprises a pump body. The internal chamber of the pump body is provided with an oil/gas separating chamber; an outlet of the oil/gas separating chamber is communicated with the oil outlet of the pump body; an inlet of the oil/gas separating chamber is communicated with a pump body gear working chamber; a chamber wall in the inlet position of the oil/gas separating chamber is provided with a spiral flow guide trough; the side wall of the oil/gas separating chamber along a horizontal axis line is provided with an exhaust port communicated with a normal-pressure chamber; the chamber wall of a normal-pressure chamber is provided with a flow guide port communicated with the gear working chamber; the flow guide port is started or closed by a floater valve. By adopting the structure, the utility model has the function of eliminating the gas in the fuel; meanwhile, the utility model has the advantages of dense structure and small volume.
Description
Technical field:
The utility model relates to a kind of gear pump, especially relates to a kind of gear pump that is used for fuel charger.
Background technique:
The existing gear pump that is used for fuel charger does not have the function of eliminating fuel oil gas, must install a gas and oil separating plant additional at the pump housing oil outlet during use, contains gas with the fuel oil of avoiding exporting.Owing to install gas and oil separating plant additional, the installation dimension that this has just not only strengthened the pump housing has increased Sealing, has also increased installation and maintenance personnel's workload simultaneously.
The purpose of this utility model is to provide a kind of gear pump that is used for fuel charger at above-mentioned existing in prior technology deficiency.
For achieving the above object, the utility model can take following technical measures to realize:
The utility model comprises the pump body, is provided with an Oil-gas Separation chamber in described pump chamber body, and the outlet of described Oil-gas Separation chamber is connected with pump body oil outlet, and its import is connected with pump body working gear chamber; On the chamber wall that is positioned at Oil-gas Separation chamber entrance location place, offer the spirality guiding gutter, offer a relief opening that is connected with the normal pressure chamber at its horizontal axis of Oil-gas Separation chamber sidewall upper edge; Offer the flow-guiding mouth that is connected with the working gear chamber on the wall of the chamber of described normal pressure chamber, described flow-guiding mouth opens and closes by float-controlled valve.
Advantage of the present utility model is to be provided with an Oil-gas Separation chamber in described pump chamber body, with on the chamber wall at the entrance location place of this chamber, offer the spirality guiding gutter, and offer a relief opening that is connected with the normal pressure chamber at this its horizontal axis of chamber sidewall upper edge; During use, fuel under high pressure oil in the working gear chamber is when entering Oil-gas Separation chamber inlet, under the effect of spirality guiding gutter, fuel oil flows towards this chamber outlet twist along the Oil-gas Separation chamber wall, because specific gravity of gas is littler than fuel oil, suffered centrifugal force is less and accumulate in Oil-gas Separation chamber horizontal axis position and enter described common pressure chamber from described relief opening indoor, the fuel oil self-pumping body oil outlet that does not contain gas is discharged, thereby reach the purpose of eliminating gas in the fuel oil, the utility model compact structure volume is little simultaneously.
Description of drawings:
Fig. 1 cuts open structural representation for master of the present utility model.
Embodiment:
As shown in the figure, the utility model comprises pump body 1, is provided with an Oil-gas Separation chamber 2 in described pump body 1 inner chamber, and the outlet 3 of described Oil-gas Separation chamber 2 is connected with pump body 1 oil outlet, and its import 4 is connected with pump body 1 working gear chamber 5; Offer the spirality guiding gutter on the chamber wall that is positioned at Oil-gas Separation chamber 2 imports 4 positions, its horizontal axis 7 offers a relief opening 9 that is connected with normal pressure chamber 8 in Oil-gas Separation chamber 2 sidewalls 6 upper edges; Offer the flow-guiding mouth 10 that is connected with working gear chamber 5 on the wall of the chamber of described normal pressure chamber 8, described flow-guiding mouth 10 is opened by float-controlled valve 11 and is closed.
