Embodiment 1

[0057]A system 10 for determining the fault point of a coal feeder, such asfigure 2 As shown, the system 10 includes a control board 101, a frequency converter 102, a motor 103, a recording device 104, a main control device 105, a signal distributor 106, and a current sensor 107; the control board 101 is connected to the frequency converter 102, and the frequency converter 102 is connected to The motor 103 is connected, and the frequency converter 102 receives the speed control command issued by the control board 101, and changes the output current according to the speed control command to adjust the speed of the motor 103. The speed control instruction may be the current output value. For example, the speed control instruction sent by the control board 101 to the inverter 102 is the first current output value, and the inverter 102 controls the output current to be the first current according to the speed control instruction. The output value is used to adjust the speed of the motor...

Abstract

The invention provides a system and a method for determining a fault point of a coal feeder, which relates to the chemical field and aims to solve the problem that the fault point of the coal feeder cannot be quickly located. The system comprises a control board, a frequency converter, a motor and a recording device, wherein the control board is connected to the frequency converter; the frequencyconverter is connected to the motor and is used for receiving a speed regulation instruction emitted by the control board, and regulating rotation speed of the motor by changing output current according to the speed regulation instruction; and the recording device is connected to the control board for recording the speed regulation instruction sent to the frequency converter by the control board.The system and the method for determining the fault point of the coal feeder provided by the invention are used for determining the fault point of the coal feeder.

Description

Technical field[0001]This application relates to the field of chemical engineering, and in particular to a system and method for determining the fault point of a coal feeder.Background technique[0002]The coal feeder is one of the key equipment of the coal-fired pulverizing system of thermal power plants. Currently, the most widely used coal feeder is an electronic weighing coal feeder. The control panel of the electronic weighing coal feeder has the functions of coal weighing, coal feeding control and fault feedback.[0003]When the coal feeder trips due to a fault, the cause of the fault can be determined by the fault code on the control panel. However, in general, a fault code corresponds to multiple possible fault causes, and technicians need to eliminate multiple possible fault causes one by one in order to determine the true cause of the fault and then determine the point of failure. For example, if the fault code on the control board is "03 trip", the corresponding fault cause m...
