The submersible pump level control cabinet has multiple protection functions such as overload, short circuit, phase loss protection, pump body leakage, motor overheating and leakage, and complete status display. It also has single pump and multi pump control working modes, multiple main and backup pump switching modes, and various starting modes. It can be widely used for automatic control in various occasions such as water supply, drainage, fire protection, sprinkler network pressurization, HVAC cold and hot water circulation in industrial and agricultural production and various buildings. The submersible pump level control cabinet has excellent internal quality, beautiful and durable appearance, and easy installation and operation, making it a safe and reliable companion for various types of water pumps.

2、 Product features:

1. Widely used: There are corresponding specialized models and specifications for various occasions, such as domestic water supply and drainage, fire protection, sprinkler, pressurization, air conditioning cooling circulation, industrial control pumps, sewage discharge. Control the motor power range from 0.18 to 250 kW.
2. Excellent Quality: Carefully designed and crafted with international and domestic renowned electrical components and high-quality standard cabinets.
3. Versatile functions: From one control to five control, the main and backup pumps can be freely selected and combined, with multiple starting methods and various control forms. Automatic fault switching. We can also design it specifically for you.

3、 Working principle:
When the liquid level in the sewage tank reaches the high detection level in the submersible pump liquid level control cabinet, current flows through the deep electrode head, and the signal is input to the control circuit and drives the switch circuit. The relay closes and the sewage pump starts to discharge. When the liquid level is below the detection level, the input signal is interrupted, the sewage pump is powered off, and the sewage discharge is completed. It can also be directly controlled using manual mode. The control circuit is stable, and the liquid level fluctuation will not affect the output circuit.
1. The structural characteristics are designed with a closed control box to prevent dust
2. The detection electrode is made of stainless steel to extend its service life.
3. It has two control modes: manual and automatic.
4. The liquid level control height can be adjusted by oneself.
5. The upper and lower limits of the controller can be set in two ways: input and output (to be selected by the user)
6. Technical indicators: Environmental temperature: -15 ℃ -+65 ℃; Relative humidity: not exceeding 90%
7. Working voltage: AC 220V ± 10% 50HZ
8. Overall power consumption:<15W
9. Control the capacity of the water pump motor: 5-22KVA, please specify when the power capacity is higher
10. Detection of pump pool depth: 1-3.5M (made according to the actual depth of the user)
11. Applicable location: Suitable for use with water flushing equipment in coal transportation systems and for controlling other sewage tanks.

4、 Multi pump working mode:
1. One for use and one for backup: Control two water pumps, I and II, which can work in either "I main and II backup" or "II main and I backup" modes.
2. Two in use and one backup: Control three water pumps, I, II, and III, which can work in three ways: "I, II main, III backup" or "II, III main, I backup" or "I, III main, II backup".
3. Three in use and one backup: Control four water pumps, I, II, III, and IV, which can work in four ways: "I, II, III main and IV backup" or "II, III, IV main and I backup" or "I, III, IV main and II backup" or "I, II, IV main and III backup".
4. Dual use: It can independently control two water pumps, I and II, or be connected through a floating ball combination to form "I for use, II for backup" or "II for use, I for backup". When the flow rate changes or the main pump fails, and the liquid level reaches the starting control point of the standby pump, the standby pump will automatically start. This type is suitable for controlling the liquid levels of two water tanks or for controlling variable flow water supply and drainage systems.
5. Three uses: It can independently control three water pumps, I, II, and III, and can also be connected through a floating ball combination to form "I, II main, III backup or II, III main, I backup or I, III main, II backup". When the flow rate changes or the main pump fails, and the liquid level reaches the starting control point of the standby pump, the standby pump will automatically start. This type is suitable for controlling the liquid levels of three water tanks or for controlling variable flow water supply and drainage systems.
6. Four uses: It can independently control four water pumps, namely I, II, III, and IV. It can also be connected through a floating ball combination to form "I, II, III main and IV backup" or "II, III, IV main and I backup" or "I, III, IV main and II backup" or "I, II, IV main and III backup". When the flow rate changes or the main pump fails, and the liquid level reaches the starting control point of the standby pump, the standby pump will automatically start. This type is suitable for controlling four water tank positions or controlling variable flow water supply and drainage systems.
7. The above modes all have manual functions, and each pump can be manually started and stopped in manual mode.
