Accompanying drawing explanation
fig. 1 is the structural representation of the hydraulic oil container of a kind of aerodynamic force starting system (hydraulic hybrid power system).
Embodiment
as shown in Figure 1, the present invention is by hydraulic oil container 1, pressure indicator 4, accumulator 7, accumulator ball valve 8, Combined hydraulic valve 9, oil hydraulic motor 10, tank drainback pipe 11, fuel tank oil outlet tube 13, fuel tank oil outlet tube ball valve 12 forms, characterized by further comprising: outlet valve 2, safety valve 3, pressure-limiting check valve 5, gas tank 6, its Placement is: outlet valve 2 is communicated with the air chamber 15 on fuel tank top, safety valve 3 is communicated with the air chamber 15 on fuel tank top, one end of pressure-limiting check valve 5 is communicated with the air chamber 15 on fuel tank top, the other end of pressure-limiting check valve 5 is communicated with the other end of gas tank 6.The pressure limiting of pressure-limiting check valve 5 changes by the spring pressure in adjustment one-way valve, and pressure limiting scope is 0.5-2.0MPa.The safety pressure of safety valve 5 changes by the spring pressure in adjustment safety valve, and pressure range is 0.8-2.0MPa gas tank 6 is generally with gas tank on car, and pressure range is 0.8-1.5MPa.Pressure indicator 4 is connected with air chamber 15, the air pressure in instruction air chamber 15.The pressed gas in air chamber is bled off when outlet valve 2 is for overhauling.
working procedure summary of the present invention is:
when oil hydraulic motor 10 operating mode (exoergic state), the hydraulic oil in accumulator 1 discharges, and get back to hydraulic oil container 1 by Combined hydraulic valve 9 and tank drainback pipe 11, in hydraulic oil container 1, hydraulic oil liquid level rises gradually.Air chamber due to ullage is an airtight space, and air can not be discharged, so the air pressure in air chamber also rises thereupon, forms the fuel feeding back pressure of oil hydraulic pump 10.
when the air pressure in air chamber 15 equals the safety pressure of safety valve 3 (scope according to circumstances set is 0.8-2.0MPa), safety valve 3 is opened automatically, releases unnecessary gas.The safety pressure of safety valve 3 is realized by the spring in adjustment safety valve 3.
when oil hydraulic pump 10 operating mode (energy accumulating state), the hydraulic oil in hydraulic oil container 1 is pumped in accumulator 7 by fuel tank oil outlet tube 13 and Combined hydraulic valve 9 by oil hydraulic pump 10.Due to the oil hydraulic pump fuel feeding back pressure effect in hydraulic oil container 1, make hydraulic oil container 1 fuel feeding along Chang, operational noise is little, and working efficiency is high.
a minimum working pressure (scope according to circumstances set is 0.5-2.0MPa) is had in the air chamber 15 that pressure-limiting check valve 5 is used to ensure hydraulic oil container 1.If when the air pressure in air chamber 1 is not enough, gas tank 6 is inflated, until close with the voltage limiting value of pressure-limiting check valve 5 by pressure-limiting check valve 5 in hydraulic oil container 1.The pressure limiting of pressure-limiting check valve 3 is realized by the spring in adjustment pressure-limiting check valve 3.
