Control system of high-efficiency dry self-priming pump set for diesel engine
The control system of the diesel engine high-efficiency dry self-priming pump group is a highly integrated and powerful system designed to ensure the stable, efficient and safe operation of the pump group. The following are the main components of the control system and their functions:
1. Core control unit:
Adopt high-performance PLC or microprocessor as the core controller, responsible for receiving sensor signals, executing control algorithms, and issuing control instructions.
Equipped with large-capacity memory and efficient processor, it can process large amounts of data and achieve rapid response.
2. Sensor network:
Including crankshaft position sensor, temperature sensor, pressure sensor, etc., for real-time monitoring of the operating status of the diesel engine and water pump.
The sensor signal is converted into a digital signal by a high-precision A/D converter for analysis and processing by the core control unit.
3. Actuator:
Receives instructions issued by the control unit, performs injection, ignition, speed regulation and other operations to ensure that the diesel engine runs in the best state.
At the same time, it also includes actuators such as valves and motors to control the flow, head and other parameters of the water pump.
4. Control strategy:
Adopt advanced control algorithms such as PID control and fuzzy control to achieve precise control of the operating parameters of the diesel engine and water pump.
According to the preset working mode or real-time working conditions, the operating status of the pump group is automatically adjusted to achieve high efficiency and energy saving.
5. Fault diagnosis and protection:
The control system can monitor the operating status of the pump group in real time. Once an abnormality or fault is found, the fault diagnosis is immediately carried out and corresponding protection measures are taken.
The fault diagnosis system can accurately identify the type of fault, such as overspeed, low speed, low oil pressure, high cooling temperature, etc., and send out an alarm signal.
Protection measures include automatic shutdown, power cut-off, etc. to ensure the safe operation of the pump group.
6. Human-machine interface:
Equipped with LCD display and indicator light, the operating status and parameters of the pump group are displayed in real time.
Users can perform parameter setting, mode selection and other operations through panel buttons or remote control.
7. Communication interface:
The control system supports a variety of communication protocols, such as RS485, CAN bus, etc., which is convenient for data exchange and remote monitoring with the host computer or remote monitoring system.
