Description
Technical field
The utility model relates to technical field of engines, particularly relates to a kind of test macro verifying engine PTO fan-out capability.
Background technology
Engine testing room realizes mainly through dynamometer machine for the measurement of engine capacity, moment of torsion, kind has electric dynamometer, electric eddy current dynamometer, hydraulic dynamometer, for other power stage (as hydraulic pump, belt pulley, generator, compressor of air conditioner etc.) on engine owing to being subject to the restriction of installation site, need a kind of loading equipemtn that can have multiple connecting mode, this loading equipemtn must communicate with other control instrument, to reach the object of synchronism detection.In engine rig test, usually run into the multiple power stage of engine, such as engine flywheel end, crank pulley, hydraulic pump, generator, compressor of air conditioner, fan etc., but by the restriction of space, fund, position in testing laboratory, usually 1 ~ 2 dynamometer machine equipment is only had, as needed in test engine other power, need to increase portable, can control, easy to operate loading equipemtn.
Utility model content
The technical problems to be solved in the utility model is: provide a kind of test macro verifying engine PTO fan-out capability.
The technical scheme that the utility model is taked for the technical matters existed in solution known technology is:
Verify a test macro for engine PTO fan-out capability, comprising: hydraulic pump and fuel tank; It is characterized in that: the oil-in of described hydraulic pump is connected with fuel tank by in-line; Described in-line is provided with filtrator, heat exchanger and flowmeter; First oil-out of described hydraulic pump is connected with retaining valve, electromagnetic proportional valve, heat exchanger, filtrator, flowmeter, retaining valve, the second oil-out successively by pressure duct; First oil-out of described hydraulic pump is connected with the oil-feed port of test macro; The output port of described electromagnetic proportional valve is connected with fuel tank by blowdown valve; Also comprise the by-pass valve in parallel with described blowdown valve.
The advantage that the utility model has and good effect are: the utility model is by regulating output pressure and the flow of hydraulic oil under different rotating speeds, can load engine flywheel end, crank pulley, hydraulic pump, generator, compressor of air conditioner etc., engine and power auxiliary output gear are examined, to find the problem of design, parts quality, assembly quality.
Accompanying drawing explanation
Fig. 1 is the structural drawing of the test macro of the utility model checking engine PTO fan-out capability;
Wherein: 1, measured power output terminal; 2, hydraulic pump; 3, retaining valve; 4, by-pass valve; 5, fuel tank.
Embodiment
For utility model content of the present utility model, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1, a kind of test macro verifying engine PTO fan-out capability, comprising: hydraulic pump 2 and fuel tank 5; Measured power output terminal 1 is connected with hydraulic pump 2 by transmission shaft, and the oil-in of described hydraulic pump 2 is connected with fuel tank 5 by in-line; Described in-line is provided with filtrator, heat exchanger and flowmeter; First oil-out C1 of described hydraulic pump 2 is connected with retaining valve 3, electromagnetic proportional valve, heat exchanger, filtrator, flowmeter, retaining valve 3, second oil-out C2 successively by pressure duct; First oil-out C1 of described hydraulic pump 2 is connected with the oil-feed port A of test macro; The output port of described electromagnetic proportional valve is connected with fuel tank by blowdown valve.When the pressure after electromagnetic proportional valve 3 exceedes limit value, blowdown valve is opened, and fuel tank got back to by hydraulic oil.Electromagnetic proportional valve, by PWM aperture, adjusts pressure and the flow of the first oil-out C1.
As preferably, on the basis of above preferred embodiment: also comprise the by-pass valve 4 in parallel with described blowdown valve.
The principle of work of this preferred embodiment is: when engine start the moment of car, because the line pressure of this patent is set up instantaneously, affects normal the car of engine, so need first by-pass valve 4 all to be opened, engine normal after car, then by-pass valve 4 cuts out, system could normal work.
Above embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
