Abstract
The present invention relates to a kind of integrated gear pumps, it includes motor, lower case, upper housing, driven gear and driving gear, the lower section of lower case is arranged in motor, lower case and upper housing are tightly connected, it is arranged in the inner cavity of upper housing after driving gear and driven gear engagement, driving gear is connect with motor output shaft；Integrated valve is arranged in the top of driving gear and driven gear, and upper casing intracoelomic cavity is divided into high pressure chest and low pressure chamber by integrated valve.The present invention has the advantages that integrated, realizes that pressure accurately controls by pressure regulator valve, can save quality and space for system.
Description
Technical field
The present invention relates to a kind of gear pump more particularly to it is a kind of integrate gear wheel flow-rate pump, pressure adjusting function
Integrated gear pump, belong to pump class field.
Background technique
Pump class product is widely applied in fuel system.But gear pump has a single function in the prior art, is unable to satisfy fuel oil
The job requirement of system, with the continuous development of technology, system compact, lightness are development trends, and pump class product is fuel oil
Key components in system, it is development trend from now on that function is integrated, and therefore, a kind of function of R & D design is integrated
Gear pump is that the technical problem solved is thirsted for always in this field.
Summary of the invention
The present invention is directed to above-mentioned problems of the prior art, provides a kind of collection oil suction, oil extraction and pressure and is controlled in
The integrated gear pump of one, is mounted in oil piping system, solves the problems, such as that gear pump has a single function in the prior art, can
Meet the job requirement of fuel system.
The invention patent technical solution:
Lower case is arranged in integrated gear pump, including motor, lower case, upper housing, driven gear and driving gear, motor
Lower section, lower case and upper housing are tightly connected, and are arranged in the inner cavity of upper housing after driving gear and driven gear engagement, actively
Gear is connect with motor output shaft；Integrated valve is arranged in the top of driving gear and driven gear, and integrated valve is by upper casing
Intracoelomic cavity is divided into high pressure chest and low pressure chamber.
The integrated valve includes valve, spring and adjusting screw, and one end of spring is fixed in adjusting screw, bullet
The other end of spring is touched with valve.
The upper housing and lower case passes through rubber sealing.
The present invention compared with prior art the utility model has the advantages that
The present invention integrates oil suction, oil extraction and pressure control function, compared with previous individually functional product, has integrated
Advantage.It realizes that pressure accurately controls by pressure regulator valve, quality and space can be saved for system, be the development side for pumping class from now on
To.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is the A-A cross-sectional view of Fig. 1.
In figure, 1, motor, 2, lower case, 3, cushion rubber, 4, upper housing, 5, driven gear, 6, high pressure chest, 7, driving gear,
8, fastening screw, 9, valve, 10, spring, 11, adjusting screw, 12, low pressure chamber.
Specific embodiment
Referring to the drawings, in conjunction with specific embodiments, the present invention is described in detail.
Embodiment
As shown, integrated gear pump, including motor 1, lower case 2, upper housing 4, driven gear 5 and driving gear 7,
The lower section of lower case 2 is arranged in motor 1, and motor 1 is connect by fastening screw 8 with pump head, and lower case 2 and upper housing 4 pass through spiral shell
Nail connection, and sealed by cushion rubber 3, it is arranged in the inner cavity of upper housing after driving gear 7 and the engagement of driven gear 5, driving tooth
Wheel 7 is connect with motor output shaft；Integrated valve is arranged in the top of driving gear 7 and driven gear 5, and integrated valve is by upper casing
Intracoelomic cavity is divided into high pressure chest 6 and low pressure chamber 12.The integrated valve includes valve 9, spring 10 and adjusting screw 11, spring
One end be fixed in adjusting screw, the other end and the valve of spring touch.
When the system is operating, electrical power, motor start to rotate, and drive driving gear rotation, and driving gear drives driven
Gear rotation, gear cavity realizes volume change, to realize oil suction oil extraction function.By adjusting screw, the pressure of adjustment spring
Contracting amount realizes that pressure is adjusted with the output pressure of control oil pump.When there is excess oil, extra oil liquid is acted on valve, works as pressure
When being enough to overcome initial tension of spring, valve is opened, and excess oil flows into low pressure chamber from high pressure chest, realizes the recycling of fuel oil.
The integrated valve, operating pressure≤0.3MPa, rate of discharge >=500L/min.
The above is specific embodiments of the present invention and the technical principle used, any to be based on technical solution of the present invention
On the basis of equivalent transformation, all belong to the scope of protection of the present invention within.
Unspecified part of the present invention is known to the skilled person technology.
