Problems solved by technology

[0004] However, the electromagnets currently used in aircraft hydraulic systems cannot increase the size and weight due to limited space and high weight requirements. Therefore, engineering designers are committed to increasing the thrust of the electromagnet without changing the size and weight. design
[0005] There are currently some ways to solve this problem, but they all bring new problems such as manufacturing design difficulties

Embodiment Construction

[0024] This part is the embodiment of the present invention, which is used to explain and illustrate the technical solution of the present invention.

[0025] A high-thrust wet electromagnet, including a magnetizer 3 with a fixed position, and an iron core assembly 5 that can move back and forth axially relative to the magnetizer 3, and a coil assembly 4 is provided over the magnetizer 3 and the iron core assembly 5; wherein, The iron core assembly 5 includes an iron core 5a, a push rod 5b and a pressure sleeve 5c. The left end of the push rod 5b is set in the magnetizer 3 and has a gap with the magnetizer 3. The right end of the push rod 5b is set in the iron core 5a and drives the movement. The iron core 5a moves axially, and the right end of the push rod 5b is arranged in the pressing sleeve 5c. When the iron core assembly 5 is in the right limit position, the iron core assembly 5 presses against the soft magnet.

[0026] The magnetic conductor 3 is fixed by the circlip 1 a...

Abstract

The invention belongs to the technical field of airplane hydraulic pressure, and discloses a high-thrust wet-type electromagnet which comprises a magnetizer fixed in position and an iron core assembly capable of axially moving back and forth relative to the magnetizer, and the magnetizer and the iron core assembly are sleeved with a coil assembly. Wherein the iron core assembly comprises an iron core, a push rod and a pressing sleeve, the left end of the push rod is arranged in the magnetizer, a gap is formed between the left end of the push rod and the magnetizer, the right end of the push rod is arranged in the iron core and drives the movable iron core to move axially, the right end of the push rod is arranged in the pressing sleeve, and when the iron core assembly is located at the right limiting position, the iron core assembly abuts against the soft magnet. According to the high-thrust wet type electromagnet, the thrust is remarkably increased, the size is not increased, the production efficiency is additionally improved, and the effect is remarkable.

Description

technical field [0001] The application belongs to the technical field of aircraft hydraulics, and relates to an improvement technology of an electromagnet, which can increase the thrust of the electromagnet, in particular to a large-thrust wet electromagnet. Background technique [0002] Wet electromagnets are widely used in aircraft hydraulic systems. [0003] As the pressure system of the hydraulic system continues to increase, the thrust requirements for the electromagnet are also increasing. Generally, the way to increase the thrust of the electromagnet is to increase the number of ampere turns and increase the cross-sectional area of ​​the iron core. It will inevitably lead to an increase in the size and weight of the electromagnet. The ampere-turn is equal to the product of the number of turns of the coil and the current passing through the coil. The larger the number of ampere-turns, the stronger the magnetic field generated. To increase the current passing through t...
