Plate-and-frame filter press circuit composition.
The circuit of the plate-and-frame filter press is mainly composed of three parts: power supply circuit, control circuit and motor drive circuit.
1.Power supply circuit: The main function is to provide a stable power supply for the entire plate and frame filter press, usually using a three-phase four-wire system to ensure the normal operation of the equipment.
2.Control circuit: responsible for receiving operation instructions, controlling the logic operation of the whole equipment, including start, stop, automatic manual switching and other functions.
3.Motor drive circuit: connect the motor and the control circuit, drive the motor to run according to the control instructions, and realize the various actions of the filter press.
How the circuit works.
1.Power supply circuit: The power supply circuit connects the external power supply to the equipment, and provides stable and pure direct current for the subsequent circuit through filtering and rectification.
2.Control circuit: The core of the control circuit is the microcontroller, which sends control signals to the motor drive circuit after logic operation according to the input instructions or sensor signals.
3.Motor drive circuit: The motor drive circuit is composed of transistors, relays and other components, which adjusts the running state of the motor according to the control signal and realizes various actions of the filter press.
Common faults and troubleshooting.
In view of the circuit faults that may occur during the operation of the plate and frame filter press, this article lists several common problems and troubleshooting methods:
1.Power failure: Check whether the power cord is damaged, whether the power switch is normal, and whether the power supply voltage is within the specified range.
2.Control failure: check whether each component of the control circuit is normal, whether the control program is wrong, whether there is external interference, etc.
3.The motor does not check whether the motor drive circuit is normal, whether the motor is damaged, whether the load is too heavy, etc.
