Abstract
The utility model relates to an alternating-current motor for an oil drilling rig. The alternating-current motor comprises a machine seat; a stator is fixedly installed on the machine seat, a rotor is rotatably assembled in the stator, one end of a rotating shaft of the rotor stretches out of the stator and is used as a transmission end, an explosionproof ventilation fan and a positive-pressure safety-improved compound type anti-explosion junction box are fixedly installed on the machine seat, the explosionproof ventilation fan is electrically connected with the positive-pressure safety-improved compound type anti-explosion junction box, and the explosionproof ventilation fan sends wind to the transmission end along the machine seat. The alternating-current motor has high reliability, high protection grade, high efficiency and low emission quantity.
Description
Technical field
The utility model relates to a kind of oil-well rig alternating current motor, belongs to the motor technology field.
Background technology
Motor is the device that converts electric energy to mechanical energy as the power of manufacturing machine operation.Threephase asynchronous particularly, have simple in structure, be easy to advantages such as control, efficient height and power are big, be widely used in the modern various machinery as driving.At present, the power of domestic petroleum rig mostly is diesel engine.Diesel engine has that volume is big, noise is big, vibration is big, and efficient is low, shortcomings such as maximum discharge.The general orientation of current development is to use alternating current motor to replace diesel engine, but have some problems in actual use: the operational environment of (one) oil-well rig is comparatively abominable, may be in the desert, construction operation such as highlands, continental shelf, coastal waters, the ambient temperature height, often precipitation, salt fog, oil gas are arranged, rarefaction of air etc., general motor cisco unity malfunction under this environment in the air; (2) general purpose motor cooling blower, terminal box are not anti-explosion products, and reliability is low; (3) general purpose motor can not so normally move under the operating mode.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, and the phase asynchronous alternating current motor that is used for oil-well rig of a kind of reliability height, degree of protection height, the high and low discharging of efficient is provided.
For achieving the above object, the utility model provides following technical scheme: a kind of oil-well rig alternating current motor, comprise support, be installed with stator on the support, be rotatably equipped with rotor in the stator, an end of this rotor shaft stretches out stator, and the end that stator is stretched out in rotating shaft is a driving end, be installed with flame-proof type ventilation blower and malleation on the described support, increase the compound anti-explosion terminal box of peace, described flame-proof type ventilation blower and malleation, increase and pacify compound anti-explosion terminal box and be electrically connected.
The iron core of described rotor is a parallel teeth punching laminated structure.
The parallel teeth width of described parallel teeth punching is 5mm to 15mm.
Described support is positioned at rotating shaft driving end one side and is provided with outlet housing.
The utlity model has following beneficial effect:
(1) adopts safe outlet housing can change air-out direction, avoid hot particle to splash, prevent that meiofauna is strayed into motor internal;
(2) motor adopts 200 class F insulations, and the higher thermal load level reduces volume, improves integral rigidity, is fit to the often needs of carrying of rig;
(3) motor adopts the flame proof ventilation blower, and the terminal box malleation, to increase peace compound explosion-proof, the body positive-pressure explosion-proof, and reliability is higher;
