Description
Technical field:
The present invention relates to gear motor field, particularly a kind of gear motor performance test detection method.
Background technology:
Gear motor is by a kind of special-purpose member that hydraulic energy transfer is mechanical energy.First it is the liquid of system offer high pressure
Force feed, then hydraulic oil drives motor gear to rotate, and produces a certain amount of moment of torsion.Reaching motor output shaft drives other workpiece to turn
Dynamic purpose.Motor performance test is a critically important link.Motor performance parameter mainly has volumetric efficiency, exports moment of torsion,
Deadstart moment of torsion and rotating speed.Wherein deadstart moment of torsion and output moment of torsion can be measured by increasing carrying.Existing survey
Test system can not detection by quantitative motor performance quality, test result inaccuracy.
Summary of the invention:
It is an object of the invention to provide one gear motor performance test method easily and efficiently.
The technical solution used in the present invention is:
Gear motor performance test method, including tested gear motor, fuel tank, main pump, it is characterised in that: this method
Comprise the following steps:
One, connecting components: the external frequency conversion motor of main pump, main pump passes through pipeline communication to fuel tank to provide hydraulic oil, high
Force feed is divided into two-way by pipeline and threeway: a road hydraulic oil is by returning to fuel tank after Pressure gauge, overflow valve and effusion meter；One tunnel
Arriving tested gear motor oil-in by pipeline, hydraulic oil drives tested gear motor to pass through Pressure gauge, overflow valve after rotating
Returning to fuel tank with effusion meter, the output shaft of tested gear motor is in transmission connection load pump, and the oil-in of load pump is by pipeline even
Pass to fuel tank, oil-out is connected to fuel tank by Pressure gauge, overflow valve；Arrange on pipeline between main pump and tested gear motor
There is gate valve logical, only to control；
Two, start and test: a, closing gate valve and start frequency conversion motor drive main pump rotate and detect main pump oil-out
Flow, record；B, open gate valve and make hydraulic oil enter tested gear motor and detect rotating speed and the oil-out of tested gear motor
Flow, record；C, regulating load pump out the oil-out pressure of hydraulic fluid port pressure and tested gear motor, keep tested gear motor to go out
Hydraulic fluid port pressure is constant, record；
Three, record data are calculated: calculate the rotating speed of tested gear motor and vent flow and be converted into its volumetric efficiency.
Described gear motor performance test method, it is characterised in that: the described step c in step 2 detects
If the pressure of tested gear is unstable, then the rotating speed regulating frequency conversion motor is stable with the oil-out flow value of stable main pump, then
Repeat step one, two, three.
Compared with prior art, the beneficial effects of the present invention is:
The present invention is simple and reasonable, manufactures easy to use, and measurement result is accurate, and error is little, and practicality, operability are very
By force.
Accompanying drawing illustrates:
Fig. 1 is present configuration schematic diagram.
Detailed description of the invention:
Below in conjunction with the accompanying drawings, by embodiment, the present invention is described in further detail:

Hydraulic oil is divided into two-way by pipeline and threeway: a road hydraulic oil is by returning to fuel tank after Pressure gauge 4, overflow valve 5 and effusion meter 6
2；Pipeline of leading up to arrives tested gear motor 1 oil-in, and hydraulic oil drives tested gear motor 1 to pass through Pressure gauge after rotating
4, overflow valve 5 and effusion meter 6 return to fuel tank 2, and the output shaft of tested gear motor 1 is in transmission connection load pump 7, entering of load pump 7
Hydraulic fluid port is connected to fuel tank 2 by pipeline communication to fuel tank 2, oil-out by Pressure gauge 4, overflow valve 5；Main pump 3 and tested gear
Gate valve 8 it is provided with logical, only to control on pipeline between motor 1；
Two, start and test: a, closing gate valve 8 and start frequency conversion motor drive main pump 3 rotate and detect main pump 3 oil-out
Flow, record；B, open gate valve 8 and make hydraulic oil enter tested gear motor 2 detect the rotating speed of tested gear motor 2 and go out
Hydraulic fluid port flow, record；C, regulating load pump 7 oil-out pressure and the oil-out pressure of tested gear motor 1, keep tested gear
Motor 1 oil-out pressure is constant, record；
Three, record data are calculated: calculate the rotating speed of tested gear motor 1 and vent flow and be converted into its volumetric efficiency.
If the pressure that the step c in step 2 detects tested gear 1 is unstable, then regulate the rotating speed of frequency conversion motor with
The oil-out flow value stablizing main pump 3 is stable, repeat step one, two, three.
The performance of motor is judged, it is determined that motor performance canonical reference GB/T according to volumetric efficiency quality and rotation speed change
7936-1987 " hydraulic pump, motor zero load discharge capacity assay method "
Above-described embodiment is only the preferably embodiment of the present invention, and in addition, the present invention can also have other to realize
Mode.It should be noted that on the premise of without departing from present inventive concept, any conspicuously improved and modification all should fall
Within entering protection scope of the present invention.
