Embodiment
Embodiment one
The uniaxial magnetic turning column liquid level meter of present embodiment such as Fig. 4 and shown in Figure 5, comprise magnetic turn over post 1, with magnetic turn over post 1 parallel near magnetic float 2 and be located at the buoyancy aid 3 on testing liquid surface.Also comprise gear train 4 and hammer body 5; Gear train 4 is mainly to be made up of with two runner 8-1,8-2 being sheathed in the rotating shaft 7 the single rotating shaft 7 that is arranged in the housing 6; Buoyancy aid 3 is through rope 9 and the pulley 10 and the first runner 8-1 solderless wrapped connection; Magnetic float 2 and hammer body 5 are wire-wrapped in the both sides of the second runner 8-2 through rope 9, and be as shown in Figure 6.
As shown in Figure 5, the uniaxial magnetic turning column liquid level meter of present embodiment also comprise with magnetic turn over post 1 parallel near magnetic float lumen 11 and hammer body lumen 12, magnetic float 2 is located in the magnetic float lumen 11, hammer body 5 is located in the hammer body lumen 12.Certainly, the variation of present embodiment is: can remove magnetic float lumen 11 and hammer body lumen 12.
As shown in Figure 4, the gear train 4 of present embodiment is fixed on magnetic and turns on the post 1.The testing liquid of present embodiment is contained in the container 100, and whole liquid level gauge is positioned at the side of container 100, and container 100 is open-topped tank bodies.
The buoyancy aid 3 of present embodiment can be selected the stainless steel ball of hollow seal or the baton round of hollow seal etc.
When rotating shaft 7 was rotated, buoyancy aid 3 was identical and opposite with the moving direction of hammer body 5 with the moving direction of magnetic float 2.That is: when buoyancy aid 3 descends with liquid level to be measured; Magnetic float 2 also descends; Hammer body 5 rises, and the gravitational torque sum that this moment, magnetic float 2 produced with buoyancy aid 3 deducts the moment of resistance sum that the difference of the gravitational torque that hammer body 5 produces should produce greater than gear train 4 and rope 9 again; When buoyancy aid 3 rose with liquid level to be measured, magnetic float 2 also rose, hammer body 5 declines, and the difference of the gravitational torque that the gravitational torque of hammer body 5 generations this moment and magnetic float 2 produce should be greater than the moment of resistance sum of gear train 4 with rope 9 generations.Magnetic float 2 driven magnetic that descend or rise are turned over post 1 upset and are realized the indication to liquid level.To this, it is following to analyze its principle of explanation theoretically.
At first we suppose:
The gravitational torque that M1-magnetic float 2 produces;
The gravitational torque that M2-hammer body 5 is produced;
The gravitational torque that M3-buoyancy aid 3 produces;
The moment (from the dynamic value of 0-M3) that M4-buoyancy aid 3 suffered buoyancy produce on the first runner 8-1;
The moment of resistance sum that M5-gear train 4 and rope 9 are produced.
When steady state (SS), the moment-equilibrium equation of liquid level gauge is: M1+M3=M2+M5+M4.
Under the effect of no any external force, buoyancy aid 3 will guarantee to float on the testing liquid surface;
1) moment of resistance sum that the difference that will guarantee the gravitational torque that gravitational torque that hammer body 5 produces and magnetic float 2 produce is produced greater than gear train 4 and rope 9, i.e. M2-M1＞M5;
2) moment of resistance sum that the difference that will guarantee the gravitational torque that gravitational torque sum that magnetic float 2 and buoyancy aid 3 produced and hammer body 5 are produced is produced greater than gear train 4 and rope 9, i.e. M1+M3-M2＞M5.
If liquid level descends, final buoyancy aid 3 will descend along with the decline of liquid level.
When if liquid level rises, final buoyancy aid 3 will rise along with the rising of liquid level.
In addition, magnetic float 2, buoyancy aid 3 and hammer body 5 will satisfy at the winding direction on the runner: when single shaft 7 rotated, magnetic float 2 and buoyancy aid 3 travel directions were in the same way and opposite with the direction of motion of hammer body 5.Usually, the rope 9 of connection buoyancy aid 3 will twine certain number of turns (more than the circle) in advance on the first runner 8-1.
Such as, the radius that we select the second runner 8-2 is 0.1 meter, the radius of the first runner 8-1 is 0.2 meter; The weight of magnetic float 2 is 1.96 newton (quality is 0.2 kilogram), and the weight of hammer body 5 is 9.8 newton (quality is 1 kilogram), and the quality of buoyancy aid 3 is 6.86 newton (quality is 0.7 kilogram).This moment M1=1.96 * 0.1=0.196 ox rice; M2=9.8 * 0.1=0.98 ox rice; M3=6.86 * 0.2=1.372 ox rice.
1) if buoyancy aid can change along with liquid level variation will guarantee that liquid level rises the time, then gear train 4 must satisfy with the moment of resistance sum M5 that rope 9 produces: M5＜0.784 N rice (being M2-M1); Therefore as long as the moment of resistance sum M5 that gear train 4 and rope 9 are produced is reduced to the 0.784 N of level value that can measure reality below the rice.
2) if buoyancy aid can change along with liquid level variation will guarantee that liquid level descends the time, then gear train 4 must satisfy with the moment of resistance sum M5 that rope 9 produces: M5＜0.588 N rice (being M1+M3-M2).We just can measure actual level value as long as gear train 4 is reduced to 0.588 N below the rice with the moment of resistance sum M5 that rope 9 produces.
Comprehensive 1) and 2), guarantee that liquid level rises or when descending buoyancy aid rise or descend along with liquid level, then gear train 4 must satisfy with the moment of resistance sum M5 that rope 9 produces: M5＜0.588 N rice.Therefore, we just can measure actual level value as long as gear train 4 is reduced to 0.588 N below the rice with the moment of resistance sum M5 that rope 9 produces.
