There are No. 1 16-1 of plunger, No. 2 16-2 of plunger, No. 3 16-3 of plunger, No. 4 16-4 of plunger, No. 5 16-5 of plunger, No. 6 16-6 of plunger and column
Fill in seven plungers of No. 7 16-7.As shown in Figure 10, according to No. 3 16-3 cylinder body rotary-top central axis institutes of No. 1 16-1 of plunger and plunger
In position, first angle sensor 41 and second angle sensor 42 in radial plunger piston motor shell corresponding position, first angle are passed
No. 3 16-3 rotary-top centers of the rotary shaft of sensor 41 and second angle sensor 42 and No. 1 16-1 of plunger and plunger are fixed to be connected
It connects, the rotary motion of plunger No. 1 16-1 and No. 3 bottoms 16-3 of plunger can be transmitted to first angle sensor 41 and second angle
In 42 rotary shaft of sensor, No. 1 16-1 of plunger can be acquired by first angle sensor 41 and second angle sensor 42
With the hunting frequency and swing angle of No. 3 16-3 cylinder bodies of plunger.
First angle sensor 41 and second angle sensor 42 are Hall element, as shown in figure 12, angular transducer rotation
The angle value and output voltage values of shaft rotation are proportional, it may be assumed that
θ=kV+b
It as shown in figure 11, is the collected voltage value time history plot of angular transducer 4.According to voltage in figure
The changing rule of value can obtain the hunting frequency f of plunger cylinder by analytic operation.
It, can according to the relationship between radial plunger piston motor revolving speed n and radial plunger piston motor plunger cylinder angle change frequency f
To obtain radial plunger piston motor revolving speed:
N=f
If Figure 12 is that first angle sensor 41 and second angle sensor 42 are mounted on the fixed position of radial plunger piston motor
Upper collected voltage signal values time history plot, obtains as shown in fig. 13 that angle value is at any time after conversion
The curve graph of variation.
It is that radial plunger piston motor eccentricity calculates mathematical model schematic diagram shown in Figure 14, wherein A point represents first angle
The position that sensor 41 is installed, B point represent the position of the installation of second angle sensor 42, and O point is radial plunger piston motor axis axle center,
Plunger cylinder bottom rotation center is R to radial plunger piston motor axis axle center distance, i.e., the diameter of round O is R, and C point is eccentric shaft circle
On arc a bit, OC is eccentric distance e.In the radial plunger piston motor course of work, point C is moved on circle O, if first angle sensor 41
It is α, β with the collected angle value of second angle sensor 42.
It is the angle value schematic symbol diagram that first angle sensor 41 acquires shown in Figure 15 and Figure 16.The angle α have it is positive and negative it
Point, set AC in the clockwise right side when institute's angulation of OA as positive value, it is on the contrary then be negative value, if the value of α in Figure 15 is negative, scheme
The value of α is positive in 16.Similarly, also there is same rule at the angle β formed by second angle sensor 42.
It is the angle value schematic symbol diagram that first angle sensor 41 and second angle sensor 42 acquire shown in Figure 17,
Whole region is divided into one, two, three, 44 different region, C by OA, OB extended line1、C2、C3、C4Respectively fall in first,
Two, the C point in three, four regions, therefore, in first area, the angle α is negative value, and the angle β is positive value；In second area, the angle α is
Positive value, the angle β are positive value；In first area, the angle α is positive value, and the angle β is negative value；In first area, the angle α is negative value, and the angle β is
Negative value.By the combination to the angle α, β positive and negative values, the region at this time where C point can be judged, according to the change of C point region
The region where rule, such as C point is changed as Time Change is one, two, three, four, one, can judge radial column Saimaa
It is (from radial plunger piston motor output shaft end direction) counterclockwise up to the direction of rotation of output shaft, whereas if where C point
Region is one, four, three, two, one with Time Change, can judge that the direction of rotation of radial plunger piston motor output shaft is
Clockwise (from radial plunger piston motor output shaft end direction).
In conclusion the present invention by sequentially connected pivoting angle data acquisition analysis system from left to right, capsul,
The radial plunger piston motor rotation-speed measuring device of connector and driving member converts rotary motion for the swing of motor piston, passes through
