Embodiment Construction

[0017] An asynchronous motor for oil field drilling, including a centrifugal fan 1 and a fan filter fixed on the top of the machine base, a junction box 2 fixed on both sides of the machine base and a heater 3 fixed on the bottom of the machine base; the fan filter includes a hexahedron A frame 4, one end face of the frame 4 is fixed with a mounting plate 6 with a fan connection port 5 on it, and at least one end face of the remaining end faces of the frame is covered with a filter layer, and the filter layer is fixed to the frame at both ends and arranged at intervals along the end face The filter grid is covered on the filter grid and is composed of a filter screen 7 fixed to the frame around it. 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 gratings are staggered with each other. During concrete implem...

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 ...
