Example Embodiment

[0017] Asynchronous motor for oilfield drilling, including a centrifugal fan 1 and a fan filter fixed on the top of the base, junction boxes 2 fixed on both sides of the base, and a heater 3 fixed at the bottom of the base; the fan filter includes a hexahedron One end surface of the frame 4 is fixed with a mounting plate 6 with a fan connection port 5, and at least one end surface of the remaining end surface of the frame is covered with a filter layer. The filter layer is fixed to the frame by both ends and arranged at intervals along the end surface. The filter grid and the filter screen 7 covering the filter grid and fixed around the frame are formed. Each filter grid is composed of a long filter sheet 8 and a short filter sheet 9 fixed to each other. The upper ends of the long and short filter sheets are bent downward, And the arrangement positions of adjacent filter grids are staggered. In specific implementation, a dense stainless steel steel wire mesh can be attached behind...

Abstract

This invention relates to an asynchronous motor including a centrifugal fan and a fan filter fixed on the top of a base, a junction box fixed on both sides of the base and a heater fixed on the base bottom, in which, the filter layer of the filter is improved so as to increase filter effect, three-phase copper lines are fixed in the box to increase current density, an anti-explosion structure is added in the heater to suit the worse situation of oil wells.

Description

technical field [0001] The invention relates to an asynchronous motor, in particular to an asynchronous motor for oil field drilling. Background technique [0002] At present, my country's oil drilling rig equipment is basically based on mechanical transmission, and there are only a small number of imported electric transmission drilling rigs in China. The key component of the electric drilling rig is the asynchronous motor for the drilling rig. However, the existing asynchronous motors cannot fully meet the needs of the field of oilfield drilling due to partial structural defects. The specific performances are as follows: 1. The asynchronous motors used in oilfield drilling often need to be equipped with heaters to directly dry the inside of the motor. Existing heaters do not have explosion-proof functions, and the electric heating components (such as electric heating wires with heat sinks, electric heating plates, etc.) are directly fixed inside the motor. The terminals ...
