- it is also a purely horizontal effect of the nozzles is conceivable. This has the advantage that the Propulsion of the nozzles can only be used to drive the centrifuge, whereby higher speeds can be achieved.
- the pressure of the centrifuge to be centrifuged can continue Fluids are determined. This can e.g. B. done by sensors that are in anyway System, e.g. B. the internal combustion engine are provided. These values are anyway evaluated by the motor electronics and can be directly connected to the centrifuge determined measured values are supplemented. Additional sensors can also be used in the system to make the most accurate statements about the condition the centrifuge.
- a speed sensor in particular an optoelectric sensor
- An alternative embodiment of the sensor would be, for. B. a tachometer generator.
- the speed of the rotor can be determined. This measurement signal can be evaluated as such, whereby z. B. can be monitored whether the centrifuge reaches its nominal speed.
- additional statements are possible. For example, using one Time recording the startup behavior of the centrifuge can be determined. About the The structure of the filter cake in the rotor can be started up indirectly monitor as the increasing inertia of the rotor lengthens the Run-up time leads.
- the time required for the centrifuge at one Changes between certain characteristic operating states can be determined. For this, additional sensors are necessary, which the achievement or the Show leaving characteristic operating states.
- the free jet centrifuge in an internal combustion engine can, for. B. signals about the Load state of the engine, its oil requirement or the delivery rate of the oil pump in the Pay attention to the lubricating oil circuit.
- the viscosity of the liquid is also a criterion for the function of the centrifuge to consider.
- the influence of viscosity on the startup behavior of the centrifuge can be considered in this way.
- a free jet centrifuge which is suitable for carrying out the described method is claimed according to claim 6.
- the centrifuge rotor is at least axially fixed a direction, the axial fixing of the rotor for a pressure sensor is used, the axial force of the rotor in the direction of the axial Determination can determine.
- the measured value determined in this way can be described in the Process wisely.
- the rotor in the housing is in stored in the axial direction without play.
- Figure 1 The system described here can be a variant of a monitoring device the function of the centrifuge is also independent of that acting on the rotor Determine the direction of the axial force.
- the generation of a continuous Measurement signal possible possible, as this is not different from that caused by the inclination of the Noise generated axial force component is dependent but this axial component only have to consider if it arises.
- the signal is also continuous regarding the measured value. It can thus z. B. the structure of the Filtercakes are tracked, making z. B. a conclusion on oil change intervals is possible.
- the centrifuge rotor is supported by a ball bearing in the housing. This can withstand the axial forces of the Take up the rotor and pass it on to the pressure sensor. In addition, thereby reducing the friction, whereby higher speeds can be achieved.
- a speed sensor is on the free jet centrifuge for monitoring appropriate. This is integrated at a suitable point in the housing.
- Tachometer generator should e.g. B. be provided at one of the bearing points of the rotor, for a fixation in the housing on the one hand and a connection on the other with the rotating rotor.
- the measurement signal of the speed sensor can be processed in the manner already described.
- a free jet centrifuge is shown schematically as z. B. for Cleaning lubricating oil of an internal combustion engine is used. The flow direction the fluid is indicated by arrows.
- the free jet centrifuge 10 has Housing 11, which is equipped with an inlet 12 and an outlet 13 is. The housing does not have to be designed separately. It can be the rotor of the free jet centrifuge just as well built into other structures of the internal combustion engine be such. B. the oil pan.
- a rotor 14 of the centrifuge is with a central tube 15 stored in a plain bearing 16. The center tube also represents the rotor inlet 17 through which the oil enters the rotor. Drive nozzles 18 serve the Oil as a rotor outlet.
- This is fixed to the rotor with its outer ring.
- the inner ring of the Ball bearing 20 is provided with an intermediate piece 21, which with a piezoelectric sensor 22 is connected. This sensor is supported in the housing 11 from. This allows the sensor to absorb the axial force caused by the rotor and sends the corresponding axial force signal f to evaluation electronics 23.
- An optoelectric sensor 24 is also provided in the housing. This can Generate a speed signal n via a marking 25 on the rotor. This will processed together with a temperature signal t in the evaluation electronics 23.
