JH1A-40 feeder controllerWidely used in metallurgy, mining, coal, building materials, chemical industry, power, grain, machinery and other industries, it can uniformly, continuously and quantitatively deliver granular and powdery materials to the receiving device. Especially suitable for situations where automatic batching, quantitative packaging, production process automation, and high feeding accuracy are required. The main feature of electromagnetic vibration feeder is that it can instantly change and open/close the material flow, so the feeding amount has high accuracy. 2. Small size, light weight, simple structure, easy installation, no rotating parts, no need for lubrication, low operating costs. 3. Due to the use of the resonance principle of mechanical vibration, the electromagnetic vibration feeder operates in a low critical near resonance state, resulting in less energy consumption. 4. Due to the continuous throwing of materials in the feeding trough during the feeding process and their jumping motion forward along a parabolic trajectory, the wear of the feeding trough is relatively small. Realize centralized and automatic control of the production process. The main use of electromagnetic vibration feeder: Electromagnetic vibration feeder is widely used in metallurgy, coal, electronics, machinery, chemical industry, building materials, light industry, grain and other industries. In the production process, it is used to quantitatively, uniformly and continuously feed block, granular and powdery materials from storage silos or funnels to the receiving device.
1、 Overview
This controller is a modified version of the electromagnetic speed control motor controller jointly designed by the former Ministry of Machinery Industry, with more stable performance and higher speed accuracy. Mainly used for speed control of AC electromagnetic speed regulating motors (slip motors), achieving constant torque stepless speed regulation. When the load is fans and pumps, it has a significant energy-saving effect.
2、 Debugging steps
Check if there is any looseness in the parts, if the fuse specifications are correct, and if the tachometer pointer is at zero position.
Connect the power supply to the motor and check if the rotation direction is consistent with the mechanical drag.
During the test drive, start the asynchronous motor first, then connect the power supply to the controller. The indicator light will turn on, and turn the speed control knob. At this time, the tachometer gradually rises. Set the speed value according to the implementation needs.
Due to individual differences in speed measuring generators, tachometer calibration and adjustment should be performed before using a new governor. First, set the speed to 1200r/min, compare the tachometer on the panel with other standard tachometers, and adjust the tachometer calibration potentiometer on the panel to make the actual speed match the displayed speed.
*High speed setting: Rotate the speed potentiometer clockwise to the bottom, adjust the feedback quantity to adjust the potentiometer, and make the speed reach the maximum fixed speed of the slip motor.
