Explosion proof distribution box, instrument box, control box, distribution cabinet, switch junction box

One control, one explosion-proof sewage pump control boxSuitable for various technical specifications of submersible sewage systems, design and produce low-voltage electrical appliances and sensor controllers with high durability according to relevant standards and industry standards. The one control one sewage pump control cabinet is particularly suitable for automatic control and protection in industrial and mining enterprises such as hotels, construction, metallurgy, chemical industry, mining, petroleum, textile, as well as underground engineering, municipal engineering, sewage treatment and other departments.

Characteristics of Control Cabinet for Control One Sewage Pump:

①The selection of branded low-voltage electrical circuits is reasonable and concise, with durable control programs, resulting in excellent system performance, flexible control, and resistance to damageInterference energyStrong strength and durable work.

②It has protection functions such as motor overload, short circuit, phase loss, pump leakage, and high temperature of motor stator, making it easy to use and maintain.

③Set up manual and automatic control functions to ensure continuous operation of equipment protection.

④Programmable control, capable of achieving single level control, multi level control, automatic alternating operation of main and backup pumps, automatic timed rotation, pressure control, etc. according to user needs

⑤Configurable touch operation human-machine interface product, high-power water pump can use frequency converter or intelligent soft start to achieve smooth start.

Working principle of one control and one sewage pump control cabinet:

1.Control the discharge float of ordinary sewage pits

The system can use one or more water pumps. When using a water pump, the float switch fluctuates up and down with the liquid level in the sewage pit. When the float is at the pump water level, it starts the submersible pump through the control cabinet to start draining water; When the float is at the stop pump water level, the float stops the operation of the submersible pump through the control cabinet. When multiple pumps are used, the backup pump automatically starts running and the control cabinet displays a fault signal for the submersible pump.

Liquid level standby pump put into operation: When the main pump flows into the collection pit with low sewage flow, high flow or main pump failure causes the liquid level to rise to another float switch, the standby pump is also put into operation.

2.Discharge control of drainage pump station

manual replacement/Fault switching: Choose either the main pump or the backup pump. When the main pump is working at high water level, if the main pump fails or the control circuit fails, each pump will be delayed and sound and light alarms will be issued. When the sewage flow into the collection pit exceeds the discharge capacity of the main pump, the standby pump is delayed and emits an audible and visual alarm

3.Discharge control of drainage pump station

Automatic alternating rotation: When the water level reaches a high level1start#(or2#After the drainage is completed, when the water level reaches the high water level for the second time, the wheel is2#(or1#When the water level of the pump reaches the high water level, both pumps are put into operation to complete the drainage and rotation of the main and backup pumps.
