Abstract

The invention relates to a motor, a frequency conversion all-in-one machine and a well cementation device, and the motor can comprise a stator which is provided with a stator ventilation channel penetrating through the stator in the axial direction of the stator; a rotor which is arranged on the radial inner side of the stator, wherein the rotor is provided with a rotating shaft extending in the axial direction of the motor and a rotor iron core installed on the rotating shaft, and the rotor iron core is provided with a rotor ventilation channel penetrating through the rotor iron core in the axial direction of the rotor iron core; and a cooling fan which is installed on the rotating shaft and rotates along with the rotating shaft, wherein the cooling fan, the stator ventilating duct and the rotor ventilating duct form a circulating air duct. According to the motor and frequency conversion all-in-one machine, the heat dissipation mode of combining air cooling and water cooling is adopted, and the heat dissipation effect can be improved. Besides, the well cementation device has a compact overall structure, the overall size can be reduced, then the overall size of the well cementationvehicle can be reduced, and the well cementation vehicle can conveniently conduct transition operation among a plurality of oil field well sites.

Description

technical field [0001] The present disclosure relates generally to the field of electric machine construction. More specifically, the present disclosure relates to a motor, a frequency conversion integrated machine and a cementing device. Background technique [0002] With the increasing global oil consumption, the demand for special equipment for oil drilling has grown rapidly, and the market size of the industry has expanded rapidly. Traditional cementing vehicles used in oil field well sites are generally driven by diesel fuel. However, with the advancement of the global goal of energy saving and emission reduction, the use of motor drives instead of traditional diesel drives has gradually become an industry development trend. [0003] Therefore, it is necessary to develop a motor, a frequency conversion integrated machine and a cementing device for the cementing vehicle equipment, so as to at least improve the problem that the diesel drive is difficult to meet the requi...
