Fig. 2 is the bright middle engine operation process figure of the present invention.
Embodiment
Below in conjunction with Figure of description, the present invention is further elaborated.
As shown in Figure 2, aeromotor complete machine ground operation method of the present invention comprises the following steps:
Engine is fixed on shelving in advance, enters in oil sealing and carry out being with the engine running oil sealing turned;
Shelving stationary power output terminal in advance, the mode that employing oil motor band turns is to replace turbo-starter; Set up small-sized Hydraulic Station and form power source, use set of gears transmission case and a soft axle of transmission supporting, through sending out attached, engine running work is moved in soft boss dribbling, power transmission line is: driven by motor hydraulic pump is delivered to oil motor through pressure duct, power is delivered to engine through gear, transmission shaft by oil motor, engine rotor band is forwarded to the rotating speed of demand.
In the present embodiment, select motor-hydraulic pump-pressure duct-oil motor-gear case-transmission shaft-Fa attached-the power transmission circuit of rotor, need to use and shelve in advance, the engine got off from test bay is moveed backward in pre-entrucking under test bay, enters between oil sealing and carries out oil sealing.Test bay then carries out other test run tasks on platform.
Use and shelve stationary engine in advance, enter between oil sealing and carry out being with the engine running oil sealing turned.Stationary power output terminal on shelve in advance, use set of gears transmission case and a soft axle of transmission supporting, move engine running work through sending out soft boss dribbling attached.
Interface reserved with gear case for oil motor is docked.Gear case is fixed on engine and shelves in advance.Gear case needs the band that can meet engine to turn requirement, and this case rotation portion will have independently lubricating system, maintenance easy to use.
For the fixed support of fixing flexible axle, these support two ends connect the cover tooth axle of the transmission shaft-motor-end of the attached end flanges dish of flexible shaft-Fa and band flexible connection respectively.
Fixed on the top of the shelf by gear case, mix up with send out end attached to positive relationship, precise and stable.
Consider transmission efficiency, the operable power of motor reduces gradually, under needing the prerequisite of power, improves the power of power source at engine work, consider the loss in power transimission process, should be able to meet the demands time power source arrives output end position after transmitting.
The output terminal of rotary power, uses high-pressure hose, connecting fluid press pump and oil motor, and the output terminal transmission of motor should, more than the rotating speed of regulation, be convenient to regulate.
Because pressure duct does not carry out dismounting in the course of the work, motor output end needs the connected mode being designed to be able to left and right switching, when oil sealing operates, pull side and drive engine rotation, during transport engine, need to pull opposite side, do not affect engine turnover.
Hydraulic pump and electric drilling match form Hydraulic Station (comprising hydraulic reservoir, valve, filter, tensimeter etc.), export high pressure liquid force feed, need to set up cooling system, possess suitable refrigerating function if worked long hours.
Hydrauliccranking system is engine when not working, and hydrauliccranking system work, drives engine running, until output terminal reaches corresponding rotating speed, after rotating certain hour, hydrauliccranking system quits work.
Pressure duct is used for transmitting Power output, motor power is converted into the rotary power that oil motor exports.Need the high pressure resistant pipeline of oil resistant, as far as possible few switching, need attach supporting joint.Outside pressure duct, will protective cover be set, protection steel plate be installed, guarantees the personal safety in work.
Motor, oil motor, hydraulic power unit and pressure duct are the main establishment part of the driven by motor oil motor that adopts of the present invention as power source.Hydraulic system is in process to stall herein, should be able to realize the disengagement function of hydraulic system, to ensure to turn in journey at engine stop band, not produce impact.
Interface reserved with gear case for oil motor docks by gear case.Gear case herein uses existing external casing to replace, and is fixed on engine and shelves in advance.Externally to be connected with the accessory drive gearbox of engine through flexible shaft after engine is shelved in advance and fixed, to transmit power.Rotation portion on external casing will have independently lubricating system (comprising fuel tank, pump, valve, filter, tensimeter), if the needs that work long hours cool, and maintenance easy to use.
External lubrication can adopt spray lubrication mode, is connected independent oil tank by external oil-in with oil-out, and it is larger that oil tank does, and can reach the effect of heating radiator like this during external work.Liquid level scale is set outside fuel tank, add fuel tank liquid level should outside degree of setting high about 2/3 just.For ensureing the flowing of lubricating oil, in external and connecting pipe entry position that is fuel tank, install supercharge pump, pressure regulating valve, the ability of buying oil of pump is at more than 0.3Mpa.
Transmission shaft, for connecting external interface and send out attached the soft shaft flange dish of end, needs accurately to locate, the test run requirement that installation requirement is gone up on the same stage.Use the existing flexible shaft of stand herein, do not need to manufacture and design.
