Embodiment Construction

[0008] The top drive motor ventilator of the oil field drilling rig includes a volute 3, a fan motor 1 is fixed on one side of the volute, an impeller 2 driven by the fan motor is inside the volute, and an air duct 4 is fixed on the air outlet of the volute. A current collector 5 is fixed at the air inlet of the volute 3 . After the current collector 5 is molded with a hyperbola, it is assembled on the side plate 2 of the volute assembly with a flange, so that the air intake forms a high-pressure airflow, so that the fan can efficiently inhale cold air from the disc brake seat. During specific manufacturing, the blower motor 1 adopts the M2JA series 5.5kW explosion-proof motor of ABB Company, and its installation method is B5 installation method. The volute 3 is welded by steel plates, and the profile of its side plate 1 is the same as that of the common volute plate, and the fan drive motor is assembled on the side plate 1; It basically coincides with the disc brake seat.

Abstract

The related ventilator for drive motor of oil-field driller comprises: a scroll case with a ventilator motor on side and a driven impeller inside, and an air-duct fixed on case outlet. This invention can cool the disk braking device at one time, and has compact structure and well practice effect with low noise.

Description

technical field [0001] The invention relates to a ventilator for motor cooling, in particular to a top drive motor ventilator for an oil field drilling rig. Background technique [0002] Due to the particularity of the operating environment of the top drive motor of the oil field drilling rig, it does not have a supporting cooling fan. Therefore, the top drive motors of various oil field drilling rigs produced in China are not equipped with ventilators at present. Contents of the invention [0003] In order to solve the problem that the top drive motor of an oil field drilling rig has no matching fan, the present invention provides a top drive motor fan for an oil field drilling rig. [0004] The present invention adopts the following technical scheme: the top drive motor ventilator of the oil field drilling rig includes a volute, a fan motor is fixed on one side of the volute, an impeller driven by the fan motor is arranged inside the volute, and an output fan is fixed o...
