Background
The oil outlet design of the original double-oil-pump double-oil-chamber oil tank is that each fuel pump is externally connected with a gasoline filter with a pressure regulator, and the return oil after the two gasoline filters the pressure regulator is collected and then returns to the left oil chamber and the right oil chamber of the double-oil-chamber oil tank through a tee joint respectively. Because of the different resistance that every petrol strained, there is the error in the cracking pressure of every air-vent valve also, causes the oil of every fuel pump and return oil pressure difference different, and the oil of two fuel pumps is just different, and then appears two grease chamber oil mass unbalance about two grease chamber oil tanks.
The pressure difference between the oil outlet and the oil return of the fuel pump is a main influence factor of the imbalance of the oil quantities of the left oil chamber and the right oil chamber of the double-oil-chamber fuel tank. The oil supply design principle block diagram of the original double-oil-pump double-oil-chamber oil tank refers to fig. 1.
Disclosure of Invention
The to-be-solved technical problem of the utility model is the car of current two grease chamber double oil pump oil tanks, the both sides grease chamber liquid level that appears the oil tank in the driving process condition very different. Compared with the prior art, the utility model discloses an improve former technical scheme's the design of producing oil and oil return system to solve this problem.
The technical scheme of the utility model is realized like this:
the utility model relates to a two grease chamber oil feeding system, its characterized in that: the oil supply of the two fuel pumps shares a gasoline filter and a pressure regulating valve, return oil respectively returns to the left oil chamber and the right oil chamber of the oil tank through a tee joint, the oil outlet pressure difference and the oil return pressure difference of the two fuel pumps are ensured to be the same, the return oil can be evenly distributed to the left oil chamber and the right oil chamber, and the oil mass balance of the left oil chamber and the right oil chamber of the oil tank with the two oil chambers is better.
A double-oil-chamber oil supply system comprises a fuel tank 1, two fuel pumps 2, a gasoline filter 6 and a pressure regulator 7;
the two fuel pumps 2 are respectively fixed in a left fuel chamber and a right fuel chamber of the fuel tank 1;
the two fuel pumps 2 are communicated with a gasoline filter 6 through an oil outlet pipe 3 and a tee joint; the oil outlet end of the gasoline filter 6 is connected with an engine; the oil return end of the gasoline filter 6 is provided with a pressure regulator 7;
the outlet end of the pressure regulator 7 is communicated with the two fuel pumps 2 through an oil return pipe 5 and a tee joint.
In the technical scheme, two fuel pumps 2 are respectively provided with a siphon seat 4 at opposite side oil chambers.
Compared with the prior art, the beneficial effects of the utility model are that:
the oil outlets of the two fuel pumps are converged into a pipeline; then, the oil is conveyed and returned through a fuel filter, so that the two oil pumps are ensured to have the same back pressure, namely the same pressure regulating valve, and further the fuel output of the two oil pumps is ensured to be consistent; the return oil returns to the left oil chamber and the right oil chamber respectively through a pipeline and a tee joint, so that the return oil is guaranteed to return to the left oil chamber and the right oil chamber on average. The difference of the working capacities of the two fuel pumps is considered, and the two fuel pumps siphon against the side oil chambers to ensure that the fuel in the left oil chamber and the right oil chamber of the fuel tank keeps balanced.

Detailed Description
The following detailed description of the embodiments of the present invention refers to the accompanying drawings.
The utility model discloses technical scheme is that the design of producing oil is strained for the external same petrol that takes pressure regulator of two fuel pumps, and the oil production of having guaranteed two fuel pump outputs is the same with return oil pressure differential, and the oil return also is through tee bend average allocation to the grease chamber about two grease chamber oil tanks, makes about two grease chamber oil tanks grease volume balanced. The design principle block diagram of the double oil chamber oil supply system refers to fig. 2.
The fuel oil is respectively output from the two fuel oil pumps 2, and is output to the gasoline filter 6 after being converged by the tee joint on the oil outlet pipe 3, one end of the gasoline filter 6 is output to the engine, and the outlet end of the pressure regulator at the other end of the gasoline filter 6 returns to the two fuel oil pumps 2 through the oil return pipe 5 and the tee joint so as to ensure that the total oil return returns to the left oil chamber and the right oil chamber of the saddle-shaped oil tank on average. In the oil return system, the left fuel pump and the right fuel pump share one pressure regulating valve, so that the oil outlet pressure difference and the oil return pressure difference of the two fuel pumps are ensured to be the same, and the oil return can be equally distributed to the left oil chamber and the right oil chamber, so that the oil quantity balance of the left oil chamber and the right oil chamber of the saddle-shaped oil tank is ensured.
One fuel pump 2 is fixed in the left fuel chamber of the fuel tank 1, and the other fuel pump 2 is fixed in the right fuel chamber of the fuel tank 1. When the engine works, the fuel oil pumped by the two fuel pumps 2 simultaneously is supplied to the gasoline filter 6 through a tee joint and the oil outlet pipe 3. The oil outlet end of the gasoline filter 6 is connected with an engine for consumption; at the return end of the fuel filter 6, there is a pressure regulator 7 to ensure that the fuel in the entire line from the outlet ends of the two fuel pumps 2 to the engine meets the pressure of the pressure regulator 7 and that the excess fuel is returned from the pressure regulator 7 to the fuel tank. The redundant fuel oil averagely returns to the left and right oil chambers of the fuel tank 1 through the oil return pipe 5 and a tee joint. Simultaneously, consider the difference of the operational capability of two fuel pumps 2, two fuel pumps 2 carry out the siphon through the siphon seat 4 of offside fuel chamber respectively simultaneously, when the operational capability of the fuel pump 2 of the left side fuel chamber is strong promptly, when the flow through the oil pipe 3 is greater than the flow of the fuel pump 2 of the right side fuel chamber through the oil pipe 3, the fuel pump 2 of the left side fuel chamber sucks the fuel of the left fuel chamber of fuel tank through the siphon seat 2 of the right side fuel chamber in order to be more than the fuel pump 2 of the right side fuel chamber and sucks the fuel of the right fuel chamber of fuel tank through the siphon seat 4 of the left side fuel chamber, reach the.
The utility model discloses the play oil of two fuel pumps gathers back external petrol and strains, and former technical scheme is that two fuel pumps play oil respectively connects a petrol respectively and strains.
