The invention relates to the technical field of lubrication of vertical pump bearings, in particular to a vertical pump bearing lubrication cooling device. The vertical pump bearing lubrication cooling device comprises a shaft, a bearing frame, an outer sleeve, a bearing gland, an upper bearing, a shaft sleeve, a lower bearing and a spiral sleeve. The spiral sleeve is connected to the shaft. The upper bearing, the shaft sleeve and the lower bearing are connected to the spiral sleeve. The spiral sleeve is provided with an oil rotating section. The oil rotating section is provided with trapezoidal threads I and trapezoidal threads II. An oil collecting groove is formed between the trapezoidal threads I and the trapezoidal threads II. The thread rotating direction of the trapezoidal threads Iis opposite to that of the trapezoidal threads II. An oil outlet pipe connecting pipe is provided with an oil outlet hole. A gland connecting pipe is provided with an oil inlet hole. An oil outlet pipe is connected between the oil outlet hole and the oil inlet hole. The vertical pump bearing lubrication cooling device solves the problem that a bearing on a vertical pump is hard to lubricate, meanwhile, the requirement for bearing lubrication at the low rotating speed can be met, the air cooling and heat dissipation functions are achieved, the temperature of the outer sleeve and the temperature of the bearings are effectively reduced, a good environment is provided for bearing running, and safe running of the vertical pump is guaranteed.
