Abstract

A proportion-adjustable electromagnet comprises a shell, a plastic package coil and a magnetic core pipe are installed in the shell, the magnetic core pipe comprises a guide sleeve, moving iron is installed in the guide sleeve, a push rod is fixedly connected to the moving iron, a plurality of oil passing holes are formed in the moving iron, threads are arranged in a hole in the rear end of the guide sleeve, and a tail cap is connected to the rear end of the guide sleeve in a screwed mode through the threads. A spring is installed between the tail cap and the rear end of the moving iron, one end of the spring is pressed on the moving iron, the other end of the spring is pressed on the tail cap, a section of threaded hole is formed in the rear end of the oil passing hole, a solenoid is connected into the threaded hole in a screwed mode, a middle hole is formed in the solenoid, a clamping part matched with a wrench or a screwdriver is arranged at the rear end of the solenoid, and the solenoid is provided with a plurality of replacement solenoid bodies. The screw tube can be replaced by detaching the tail cap from the guide sleeve. The electromagnet can solve the problem that most of hydraulic system pressure control is unstable due to valve control.

Description

technical field [0001] The invention relates to an electromagnet, in particular to a proportional electromagnet, and belongs to the technical field of electromagnet manufacturing. Background technique [0002] The proportional electromagnet is a commonly used component in the hydraulic control system. It is used in conjunction with the hydraulic valve to control the hydraulic system. In the hydraulic control, the pressure is required to be stable and the fluctuation is reduced. The stability of the system pressure has a greater relationship with the electromagnet. The armature (moving iron) of the electromagnet is provided with an oil hole (liquid hole), which is used to pass the liquid to balance the pressure when the armature moves, and the diameter of the oil hole is inconsistent throughout the length, so that it can be generated during the movement of the armature. Damping, in the case of satisfying the response time, the action of the valve can meet the requirements of ...
