When the pressure reaches the set value, the pressure switch will send a signal to control the start or stop of the water pump. Pressure switches are widely used in systems that require constant pressure water supply, such as urban water supply and high-rise building water supply.
The liquid level switch is used to monitor the liquid level height and is commonly used in applications such as water towers, pools and water tanks. When the liquid level reaches the set height, the liquid level switch will send a signal to control the start or stop of the water pump to prevent the water pump from idling or overflowing.
Time relay is used to realize the timing control of water pump, and can set the start and stop of water pump in a specific time period. Time relay is widely used in systems that require timed water supply, such as agricultural irrigation and industrial water.
The control panel is the interface for operators to interact with the water pump control box, usually equipped with buttons, indicator lights and display screens. Through the control panel, operators can easily monitor and operate the water pump control box and understand the operating status and fault information of the water pump.
The power module is used to provide stable power to all electrical equipment in the control box to ensure the normal operation of the control system. The power module usually includes components such as transformers, rectifiers and voltage stabilizers.
In addition to the above main components, the water pump control box may also include some auxiliary equipment, such as fuses, terminal blocks, signal relays and isolation transformers. These devices play an important role in ensuring the safety and reliability of the system.
Modern water pump control boxes are usually equipped with communication modules to realize communication with the host computer or remote monitoring system. Common communication methods include RS485, Modbus, Ethernet, etc. Through the communication module, the water pump control box can exchange data with other devices to achieve more complex control and management functions.
The display is used to display the operating status and parameters of the water pump in real time, such as current, voltage, power, pressure, liquid level, etc. Through the display, the operator can intuitively understand the working conditions of the water pump and promptly discover and deal with abnormal problems.
