Embodiment 1

[0062] Such as figure 1 As shown, according to the first aspect of the present invention, a kind of impeller fault detection method of a turbocharger is proposed, the method comprising:

[0063] Step 102, obtaining the standard rotational speed of the turbocharger and the standard number of blades of the impeller;

[0064] Step 104, obtaining the actual rotational speed of the turbocharger;

[0065] Step 106, determine the actual number of blades of the impeller according to the number of standard blades, the standard speed and the actual speed;

[0066] Step 108, according to the number of standard blades and the actual number of blades, determine the fault condition of the impeller.

[0067] This embodiment provides a turbocharger impeller fault detection method. Specifically, the turbocharger is a core component of a supercharged engine, and the impeller may wear or break after a long period of use. Once the impeller wears or Damage may cause damage to the supercharger i...

Embodiment 2

[0071] Such as figure 2 As shown, according to an embodiment of the present invention, a method for detecting a fault of an impeller of a turbocharger is proposed, the method comprising:

[0072] Step 202, obtaining the standard rotational speed of the turbocharger and the standard number of blades of the impeller;

[0073] Step 204, obtaining the actual rotational speed of the turbocharger;

[0074] Step 206, according to the first formula, calculate the actual number of blades of the impeller;

[0075] Step 208, according to the number of standard blades and the actual number of blades, determine the fault condition of the impeller.

[0076] In this embodiment, real-time monitoring of the actual speed of the turbocharger during operation, the standard speed of the turbocharger, the real-time monitoring of the actual speed of the turbocharger and the number of standard blades of the impeller are introduced into the first formula , to calculate the actual number of blades ...

Embodiment 3

[0080] Such as image 3 As shown, according to an embodiment of the present invention, a method for detecting a fault of an impeller of a turbocharger is proposed, the method comprising:

[0081] Step 302, obtaining the standard rotational speed of the turbocharger and the standard number of blades of the impeller;

[0082] Step 304, obtaining the actual rotational speed of the turbocharger;

[0083] Step 306, determine the actual number of blades of the impeller according to the number of standard blades, the standard speed and the actual speed;

[0084] Step 308, judging whether the standard number of blades is equal to the actual number of blades, if so, go to step 310, if not, go to step 312;

[0085] Step 310, determining that the impeller is not faulty;

[0086] Step 312, determining that the impeller is faulty.

[0087] In this embodiment, after calculating the actual number of blades of the impeller according to the first formula, it is judged whether the number of...

Abstract

The invention provides an impeller fault detection method and device, an engine system, operation equipment and a medium. The impeller fault detection method for the turbocharger comprises the steps that the standard rotating speed of the turbocharger and the standard blade number of an impeller are obtained; the actual rotating speed of the turbocharger is obtained; determining the actual blade number of the impeller according to the standard blade number, the standard rotating speed and the actual rotating speed; and determining the fault condition of the impeller according to the standard blade number and the actual blade number. According to the technical scheme, the rotating speed of the turbocharger is monitored in real time, the actual blade number of the impeller is calculated, then the fault condition of the impeller is judged, the impeller blades can be monitored in time when the impeller blades start to be damaged at the early stage, on the premise that the impeller fault detection accuracy is guaranteed, the fault detection timeliness is improved, and the fault detection efficiency is improved. And the effect of protecting the turbocharger, the engine and even the personal safety is achieved.
