Requirements for the use of water pump electrical automatic control cabinet
Switching mode of main and backup pumps for multi pump control in the water pump control cabinet:
Not specified as a regular type, use a manual switch to select the main pump and backup pump before starting up. After the main pump fails, the backup pump will automatically start. Generally, this method is used for controlling the main and backup pumps.
AS: timed automatic switching/manual switching
Suitable for situations where the main and backup pumps need to be used alternately at regular intervals, so that the long-term continuous working time is evenly distributed between the main and backup pumps. The regular switching time is 8-12 hours, which is a selective type. When there is no need for timed automatic switching, the switch can be switched to manual switching mode to select the main and backup pumps. This model has a backup pump self switching function.
AC: Alternating automatic switching/manual switching
The selection of main and backup pumps requires alternating working environments. Every time it is started, the main and backup pumps are exchanged. When there is no need to alternate, the switch can also be switched to manual mode to select the main and backup pumps. This model has a backup pump self switching function.

Determination of the starting method for the electrical automatic control cabinet of the water pump
Generally, water pumps with motor power below 15KW are started directly.
Z: Sewage pumps above 15KW are generally started using self coupling pressure reduction, and fire and sprinkler pumps can also be started using this method.
Y: If there are no special requirements for other models of water pumps above 15KW, they are generally started using the Y - △ pressure reduction starting method.
R: If you want to further reduce the impact on the power supply and motor during starting, extend the mechanical life, completely eliminate water hammer and noise, and achieve energy saving, you can use soft starting method. Our company's BYK control cabinet is equipped with imported high-quality soft starters, which have superior performance and high reliability.

By using an external electric pressure gauge or pressure controller, it is possible to automatically turn on and off the pump in response to changes in network pressure. Large scale application in domestic water supply and fire pressure boosting systems. As this box is also suitable for controlling water pumps with Key float switches and remote control with limit switch buttons, it is a 'universal interface' motor control box with a wide range of applications.
S-type: Time controlled type. This control box does not have a time setting button or display, and users can control the opening and closing of the water pump according to their timing needs. Suitable for controlling various timed and regular intermittent working modes.
X-type: Fire specific type. This model is designed according to the National Fire Protection Center, and the start of the fire sprinkler pump can be manually operated by ① the chassis panel; ② Each fire hydrant button or pressure switch is activated; ③ The DG24V of the fire control center is activated, and there is a signal contact for the pump to stop and start in the fire control center as an indication.

Control principle of water pump electrical automatic control cabinet
The soft start control device utilizes advanced microprocessing to control high-power thyristor components, achieving functions such as software start, soft stop, and power saving for AC induction motors. Soft start refers to the process in which the output voltage of a device increases in a regular manner, causing the controlled motor voltage to rise from zero to full voltage, and the corresponding speed smoothly accelerates from zero to the rated speed. Soft stop refers to the process in which the output voltage of the device decreases according to a certain requirement, causing the controlled motor voltage to drop from full voltage to zero, and the speed to smoothly decelerate from the rated speed to zero accordingly. Energy saving operation refers to the automatic adjustment of the output voltage of the device based on the load situation to improve the power factor of the motor during light load operation, in order to achieve the goal of energy saving. Soft start can make the starting and stopping torque curves of the water pump approach the pump torque characteristic curve, minimizing the electrical and mechanical starting impact of the pump and system, making the starting extremely reliable.

Eliminating the surge current during startup. Reduce motor losses.
4. Efficient and energy-saving
When the motor is under light load, the soft starter can reduce the terminal voltage, improve the motor power factor, and achieve energy-saving under light load.
5. Soft parking function
The soft parking function can prevent the water pump from experiencing the 'water hammer' effect.
6. Easy to operate, stable to run, and reliable
Automated control can be put into safe and continuous operation without maintenance after the system is debugged and running normally.
7. Complete protection function
It has multiple protections such as overcurrent, overvoltage, overload, phase loss, short circuit, overheating, etc.
