Embodiment Construction

[0011] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0012] See figure 1 The improved structure of a sliding sleeve of a linear motor mover shown includes a sliding sleeve 1 . In the present invention, a nickel-based alloy layer 2 is provided in the radial direction of the sliding sleeve 1 , and a non-magnetic material protective layer 3 is provided on two parallel end surfaces of the sliding sleeve 1 . Therefore, the wear resistance and corrosion resistance of the sliding sleeve 1 and the service life of the linear motor can be improved through the nickel-based alloy layer 2 . In addition, the magnetic induction lines can be effectively separated by the protective layer 3 of the non-magnetic material, and the strength of the magnetic field can be maintained when the matching magnetic steels are arranged alternately, so that the motor can still maintain high-efficiency working performance under high-spee...

Abstract

The invention discloses an improved structure of a sliding sleeve of a linear motor rotor. The improved structure comprises the sliding sleeve. A nickel base alloy layer is arranged in the radial direction of the sliding sleeve, and non-magnetic material protection layers are arranged on the two parallel end surfaces of the sliding sleeve. A wear-resisting and corrosion-resisting layer is formed after spray welding is carried out on the radial surface of the sliding sleeve, and the service life of a linear motor is prolonged. Meanwhile, the non-magnetic material protection layers are arranged on the two parallel end surfaces of the sliding sleeve in a covering mode so that magnetic induction lines can be effectively separated. When the non-magnetic material protection layers and magnetic steel are arranged alternately, the magnetic field intensity can be maintained, and high-efficiency work performance of the linear motor under the long-time running condition can be kept.

Description

technical field [0001] The invention relates to a linear motor, in particular to an improved structure of a sliding sleeve of a mover of a linear motor. Background technique [0002] At present, due to the needs of oil production engineering in oil fields, the technology of oil production equipment has been continuously developed and improved. As a new technology of oil production equipment, linear motors have become cost-saving and energy-saving equipment. The linear motor directly converts electrical energy into mechanical energy of linear motion, without any transmission device of intermediate conversion mechanism, thereby greatly improving oil production efficiency. [0003] The sliding sleeve of the mover of the traditional linear motor for oil production is directly in contact with crude oil, which not only affects the performance of the linear motor, but also causes a large loss of the magnetic flux of the mover, reducing the working efficiency of the linear motor. ...
