Technical field
The utility model relates to a kind of confession pressing system of fluid motor-driven oil sources.
Background technique
Along with gradually becoming strong of China's economic strength, the development of type aircraft is also constantly regenerated upgrading.Aircraft need make iron bird platform to verify the various experimental performances of aircraft in the development stage.Fluid motor-driven oil sources has very important effect as the power source of iron bird platform, it mainly uses No. 46 antiwear hydraulic oils as medium, export certain pressure, flow, be connected to plane simulation device iron bird platform by ground-based duct, meet the usage requirement of iron bird platform motor and the cleaning systems of iron bird platform.
Type aircraft iron bird platform also improves a lot to the physical property such as pressure, flow needed for test.Tradition large discharge, high pressure hydraulic system pressure control to be undertaken by the mode of system pressure regulating, and namely pumping source is in parallel to system voltage supply by several pump assembly parts, is provided with pressure regulator valve in systems in which to system pressure regulating.Due in aircraft iron bird platform debug process, each pressurized strut continuous action time is short, large discharge is needed during action, keep high pressure conditions for a long time again after action puts in place, do not need flow, but in system pressure regulating mode, for meeting this kind of need of work of pressurized strut, just need to allow pump be in full power operation state all the time, the working life of the key components such as pump, valve can be had a strong impact on so on the one hand, the significant wastage of the energy can be caused on the other hand.
Model utility content
The purpose of this utility model be to provide a kind of fluid motor-driven oil sources for pressing system, to solve, the energy loss that legacy system voltage regulating mode occurs is large, components and parts hold flimsy problem.
In order to realize above object, the technological scheme that the utility model adopts is: a kind of confession pressing system of fluid motor-driven oil sources, comprise the voltage supply pipeline and return line that are connected with fuel tank, described voltage supply pipeline is connected with the variable displacement pump of one group of parallel connection, the oil outlet of variable displacement pump and return line are all for being connected to plane simulation device iron bird platform by ground-based duct, the control port of every platform variable displacement pump is all connected with the filler opening of proportional pressure control valve or remote pressure regulating valve by an one-way valve, and the oil outlet of proportional pressure control valve or remote pressure regulating valve is communicated with return line.
Safety valve is serially connected with between the oil outlet of described variable displacement pump and return line.
All stable-pressure device is connected with between the control port of every platform variable displacement pump and the filler opening of one-way valve and proportional pressure control valve or remote pressure regulating valve.
The oil outlet place of every platform variable displacement pump is equipped with an one-way valve.
Controlling while carrying out pressure flex point by the Variable plunger pump of a proportional pressure control valve or the parallel connection of remote pressure regulating valve logarithm platform for pressing system of fluid motor-driven oil sources of the present utility model, identical with the delivery pressure realizing these several pumps, the required physical property such as pressure, flow when meeting aircraft iron bird platform pressurized strut debugging, avoids that the energy loss that legacy system voltage regulating mode occurs is large, components and parts hold flimsy situation.Along with society is to the progressively attention of energy-saving and emission-reduction, the long-range voltage regulating mode that this system adopts will more and more be widely used, and has good promotional value.
Accompanying drawing explanation
Fig. 1 is the structure principle chart of the voltage supply system embodiment of fluid motor-driven oil sources.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the utility model is described further.
Be illustrated in figure 1 the structure principle chart of the voltage supply system embodiment of the utility model fluid motor-driven oil sources, as seen from the figure, this system comprises the voltage supply pipeline and return line that are connected with fuel tank, voltage supply pipeline is connected with the constant pressure variable displacement pump 7 of one group of parallel connection, the filler opening of variable displacement pump and voltage supply pipeline connection, the return line of its oil outlet and system is all for being connected to plane simulation device iron bird platform (test products) by ground-based duct, the control port of every platform variable displacement pump all by flexible pipe 1 by its oil circuit control after the one-way valve 3 of correspondence mixes, pressure regulation is carried out after being connected with the filler opening of proportional pressure control valve or remote pressure regulating valve 4 again, the oil outlet of proportional pressure control valve or remote pressure regulating valve 4 is communicated with return line.
Safety valve 5 is serially connected with, for limiting maximum pressure between the oil outlet of variable displacement pump and return line.
In addition, between the control port and the filler opening of one-way valve and proportional pressure control valve or remote pressure regulating valve of every platform variable displacement pump, stable-pressure device 2 is all connected with.
The oil outlet place of every platform variable displacement pump is equipped with an one-way valve 6.
Working principle of the present utility model is as follows: the constant pressure variable displacement pump comprising two or two more parallels for pressing system, passing ratio relief valve or remote pressure regulating valve pressure regulation can realize working under multiple stage constant pressure variable displacement pump in parallel is all in pressure flex point, and it is identical to cut this force value.When pressurized strut action, the constant pressure variable displacement pump swash plate of all parallel connections is all adjusted to maximum value, can be used for large discharge, after pressurized strut puts in place, the constant pressure variable displacement pump swashplate angle zero of all parallel connections, pump is in pressure flex point state, and pump delivery outlet keeps high pressure, but output flow is zero, and pump power demand is minimum.Like this, pressurized strut test requirements document can be met, also effectively can reduce power, extend components and parts working life.
This working medium required for confession pressing system is N46 antiwear hydraulic oil, and design discharge is 280L/min × 2, and working pressure is 28MPa, can realize the step-less adjustment of about 2 ~ 28MPa.
Above embodiment only understands core concept of the present utility model for helping; the utility model can not be limited with this; for those skilled in the art; every according to thought of the present utility model; the utility model is modified or equivalent replacement; any change done in specific embodiments and applications, all should be included within protection domain of the present utility model.
