Abstract

The electromagnetic assembly comprises a shell, an armature, a pole shoe, a first rod, a permanent magnet and a coil, a containing cavity is formed in the shell, the armature is arranged in the containing cavity and can move in the containing cavity in the length direction of the shell, the pole shoe is connected with the shell, one end of the pole shoe extends into the containing cavity, and the other end of the pole shoe extends into the first rod. The pole shoe and the armature are arranged at intervals in the length direction of the shell, the first rod is arranged in the pole shoe in a penetrating mode, one end of the first rod is connected with the armature, one end of the first rod extends out of the containing cavity, the first rod can move in the length direction of the shell along with the armature, the permanent magnet is arranged on the pole shoe in a sleeving mode and located in the containing cavity, and the coil is arranged in the containing cavity. The coil surrounds the armature and the pole shoe, makes contact with the permanent magnet and is suitable for being connected with an external power source. The electromagnetic assembly is high in energy conversion efficiency and high in opening and closing response speed.

Description

technical field [0001] The invention relates to the technical field of electromagnets, in particular to an electromagnet assembly. Background technique [0002] As the basic component in the electromagnetic unloading system of the mining pumping station, the intrinsically safe electromagnet is the key to realize the intelligent automatic liquid supply on demand in the fully mechanized mining face. Through the control of the on and off of the electromagnet, the action of the electromagnetic pilot valve in the electromagnetic unloading valve is driven, so that the unloading port of the main valve is continuously closed and opened, and the process of pressurization and unloading of the unloading system is realized, so as to satisfy the comprehensive requirements of the unloading system. The intermittent liquid demand of the working face load is adopted, and the liquid is supplied to the system in a timely and accurate manner, and the liquid supply pressure of the pump station i...
