Description
Technical field
The present invention relates to a kind of gear rotational speed test experience device, particularly relate to contactless gear rotational speed technical field of measurement and test.
Background technology
High-pressure gear effusion meter in the design process, need to consider the impact of following factor: (1) gear is to use permeability magnetic material, also
It is with non-magnet material, as the strong permeability magnetic material such as 45 steel, rustless steel 2gr13 both can be selected, it is possible at weak magnetic conduction and non-magnetic material
Magnet steel is installed additional on material;For weak permeability magnetic material and the gear of non-magnet material, the layout of method and the magnet steel installing magnet steel additional to be considered
Mode;(2) non-magnet material that housing can use, leads if the material of housing can be that stainless steel 304, aluminium alloy, cast iron etc. are weak
Magnetic or non-magnet_conductible material;(3) gear velocity sensor of which type is applicable to the measurement of gear meter, such as selectable survey
The sensor of amount gear rotational speed has: inductance type, magneto-electric, Hall-type three kinds;(4) gear velocity sensor installation site is really
Fixed;(5) gear velocity sensor can penetrate the determination of the maximum gauge that housing measures.The selection of these parameter, materials etc.
It is required for being solved by experiment with determining, but if such experiment is done, for different types of gear rotational speed on effusion meter
Sensor, the gear of different magnetic conductive material, the different housing of magnetic conductive material, the different installation sites of sensor, sensor
The maximum gauge etc. that can penetrate housing is tested, and after being required for producing different types of experimental prototype, just can test, and this must
By producing huge waste, add the cost of product.
For the above situation, in order to reduce production cost, the present invention devises " a kind of contactless gear rotational speed detection reality
Experiment device ", it can simulate following experiment: (1) difference is led according to the practical situation of gear meter in this laboratory table
The gear of magnetic material;(2) housing of different magnetic conductive materials;(3) different types of gear velocity sensor;(4) sensing
The different installation sites of device;(5) sensor can penetrate the experiment such as maximum gauge of housing.Tooth is determined finally according to experimental result
The type of flowmeters gear velocity sensor, the material of gear, the material of housing, the installation site of sensor, sensor need
Penetrating the suitable thickness etc. of housing, the design for gear meter provides foundation, thus avoids doing experiment on effusion meter and carried
The waste of the production cost come.
Summary of the invention
Gear meter operation principle is when there being liquid to pass through gear wheel flow-rate timing, and gear can rotate, fluid with liquid flowing
Flow signal be converted to the tach signal of gear, then extract turning of effusion meter gear by contactless gear velocity sensor
Speed signal, then tach signal is transformed into the flow signal of effusion meter.The gear rotational speed of gear meter is measured and full depth tooth round
The measurement difference of speed is: between tested gear and the speed probe of effusion meter, across the housing (not magnetic conduction) of effusion meter,
And common tested gear and sensor distance is air.
For the gear meter of low pressure, angular encoder can be contained on a gear output shaft of gear meter, and then
Measured the gear rotational speed of effusion meter by angular encoder, current this technology is the most ripe, but for high-pressure gear effusion meter

Rotating speed, is necessary for installing additional high pressure rotary sealing on the gear output shaft of gear meter, thus can produce the biggest pressure and damage
Consumption, so, the gear rotational speed of high-pressure gear effusion meter can not be measured by the mode of angular encoder, can only take contactless
Metering system;At present, gear meter uses gear velocity sensor to carry out the rotating speed of prototype gear effusion meter gear, then
Gear rotational speed signal reconvert becomes the flow signal of gear meter, and wherein, gear velocity sensor is arranged in the cloth of gear face
The mode of putting is referred to as end face arrangement, and gear velocity sensor is arranged in the arrangement of gear top and is referred to as radial arrangement mode.
The present invention solves its technical problem and the technical scheme is that
This experimental provision is that the gear meter of end surface measurement mode is reduced to the gear (9) that driven by motor (12) and solid
End face measurement of rotating speed assembly (4) composition being scheduled on base assembly (2), the end face tachometric survey of simulation gear meter, its
In, housing cap test (16) is the housing of simulation gear meter, on housing cap test (16), passes equipped with gear rotational speed
Sensor (13);The gear meter of radial measurement mode is reduced to the gear (9) that driven by motor (12) and is fixed on
Radial direction measurement of rotating speed assembly (5) composition on base assembly (2), simulates the radial direction tachometric survey of gear meter wherein, shell
Body cap test (16) is the housing of simulation gear meter, on housing cap test (16), equipped with gear velocity sensor (13).
The present invention, compared with background technology, has the beneficial effect that
Gear (9) is by the stainless steel 304 of magnetic conduction, the carbon steel of magnetic conduction, " non-magnetic rustless steel 2gr13 installs Magnet additional ", " aluminum conjunction
Gold installs Magnet additional " make four kinds of gears of different magnetic property;Housing cap test (16) is by non-magnetic rustless steel 2gr13, aluminum
Two kinds of cap tests of different magnetic property made by alloy;The thickness of housing cap test (16) is respectively 1mm, 1.5mm, 2mm, 3mm
Four kinds.
Therefore the present invention can simulate the gear of different magnetic conductive materials of gear meter, the housing of different magnetic conductive material, different survey
The amount thickness of shell of position, the different positions of sensor, different types of gear velocity sensor (13), find therewith
Position and sensor that gear material that match, that economy optimum, performance is optimal, case material, sensor are installed can penetrate
Thickness of shell etc..The present invention is that high-pressure gear effusion meter provides design considerations.
