Abstract

The invention relates to a new energy vehicle electronic water pump rotor axial clearance detection device and a control method thereof, and belongs to the technical field of electronic water pump rotor axial clearance detection equipment. The side edge of the rotor shaft magnetic jacking assembly is provided with a displacement sensing detection assembly which is in movable contact with the rotor shaft. The rotor shaft magnetic jacking assembly comprises a jacking rack, a top plate is arranged in the jacking rack, a magnetic jacking seat which is in magnetic jacking with the rotor shaft is arranged between the upper end of the top plate and the rotor shaft, and the magnetic jacking seat is provided with a magnetic ring which is sleeved with the magnetic jacking seat in a clamping and embedding manner. The device has the advantages of simple structure, convenient detection and high use efficiency. The problem that after the impeller and the isolation sleeve are assembled, no gap exists or the gap is too large, and scrapping is caused is solved. And non-contact displacement sensing detection is realized by adopting a magnetic force principle, so that the structural integrity of the rotor shaft is protected while the detection accuracy is ensured.

Description

technical field [0001] The invention relates to the technical field of electronic water pump rotor axial clearance detection equipment, in particular to a new energy vehicle electronic water pump rotor axial clearance detection device and a control method thereof. Background technique [0002] When construction machinery is running, especially our water pump machinery, pump shafts of submersible pumps such as vertical axial flow pumps and long-axis axial flow pumps will move. The reasons can be basically divided into two situations: one is that there is a gap between the bearing and the end cover, and the bearing is not fixed by the end face; the other is that the long-term operation causes the thrust bearing to be worn, and the bearing cannot support the pressure of axial force. In addition, due to the existence of axial clearance, normal rolling bearings will also move, but the amount of movement will vary depending on the pump body type. Generally speaking, the larger th...
