product overview
The HDLH automatic water supply control cabinet is composed of an automatic part, peripheral operation execution mechanism, motor comprehensive protection, and various other sensing devices. It is an economical, practical, safe, reliable, and easy to maintain automatic water supply device based on power frequency to control the start and stop of the water pump motor. Based on years of experience in water pumps and pump control equipment, the product has been carefully designed after repeated optimization and processing by experts in the field of automatic control. The various models of the product have functions such as main circuit short circuit, phase loss, overload, and pump casing leakage for dedicated pumps, as well as stator winding overheating protection, which can be used in conjunction with the efficient and reliable operation of the water pump. In order to effectively control various signal sources in different situations, TYK automatic water supply control cabinet is designed with pressure control type, temperature control type, time control type, air conditioning joint control type, submersible sewage pump special type, and fire control type based on liquid level control. If users require other special devices, I can design and manufacture them specifically. This control cabinet uses high-quality low-voltage electrical appliances, sensors, and sensing devices, resulting in superior quality, durability, and high control accuracy.

Functional principle and purpose
1、 Control mode
1. One in use and one backup: Control two water pumps, 1 # and 2 #. When in automatic mode, they can work in either "1 # main and 2 # backup" or "2 # main and 1 # backup" states. When the main pump fails, the backup pump will automatically start working. When "manual" is exceeded, the control button on the panel will be used. If the user requests to add a "dual-use" mode (i.e. using two pumps simultaneously), please provide detailed instructions when placing an order;
2. Two in use and one backup: Control three water pumps, 1 #, 2 #, and 3 #, which can work in three states: "1 #, 2 # main and 3 # backup" or "2 #, 3 # main and 1 # backup" or "1 #, 3 # main and 2 # backup". When the main pump fails, the backup pump will automatically start working. When starting manually, use the operation button to control it. If one main pump is turned off, it will become "one in use and one backup". If the user requests to add a "three in use" working mode (three pumps can be used simultaneously), please provide detailed instructions when placing an order;
3. Three in use and one backup: Control four water pumps 1 #, 2 #, 3 #, and 4 #, which can work in four states: "1 #, 2 #, 3 # main and 4 # backup" or "2 #, 3 #, 4 # main and 1 # backup" or "1 #, 2 #, 4 # main and 3 # backup" or "1 #, 3 #, 4 # main and 2 # backup". When the main pump fails, the backup pump will automatically start working. When starting manually, use the panel operation button to control. If one main pump is turned off, it will become "dual-use and one backup". If two main pumps are turned off, it will become "one in use and one backup". If the user requests to add a "four use" working mode (i.e. using four pumps simultaneously), please provide detailed instructions for ordering.
2、 Control method
1. Y "liquid level control: This type of control cabinet is equipped with a key float switch or a high-performance electronic liquid level controller, which can automatically control the start and stop of the water pump according to the level of the liquid;
2 、 P "pressure control: This type of control cabinet is equipped with an external electric contact pressure gauge. The pressure controller is independent of the pressure and can automatically control the start and stop of the water pump according to the high or low pressure of the pipeline network. It is also suitable for control using various methods such as float switches, limit switches, and button remote control. It is a" universal interface "motor control cabinet with a wide range;
3. Temperature control of "T": This type of control cabinet is equipped with a temperature sensor outside, which can be adjusted according to the temperature of the conveyed medium. Automatically control the start and stop of the water pump. Applied to constant temperature, exchange unit systems, etc;
4. S "time control: This type of control cabinet is equipped with a time controller that can automatically control the start and stop of the water pump according to the user's pre-set time sequence, and is used for equipment that requires timed control;
