IV. Ordering Information for YE4 Three-Phase Asynchronous Motors

Ordering Instructions

Please specify the model, rated power, number of poles, voltage, frequency, and installation structure type of the motor when ordering. Different manufacturers may have special ordering requirements or custom options, such as whether a double shaft extension is needed, reversing the position of the junction box, reverse rotation of the shaft, or manufacturing it as a wet tropical or outdoor corrosion-resistant type. If there are any special requirements, they must be clearly stated in the contract and prior contact with the manufacturer is necessary.

Application of YE4 Motor in Submersible Pump

Provide power

The YE4 electric motor can serve as a power source for submersible pumps, driving the impeller of the submersible pump to rotate and generate centrifugal force, thereby realizing the liquid conveying function. This is because the YE4 electric motor has high efficiency, effectively converting electrical energy into mechanical energy to meet the power requirements of submersible pumps.

Adapt to Multiple Work Scenarios

In agricultural irrigation, the YE4 electric motor, combined with submersible pumps, can extract water from underground sources for irrigating farmland. Due to the high efficiency and energy-saving characteristics of the YE4 electric motor, it can reduce irrigation costs and improve irrigation efficiency.

In the field of industrial water treatment, such as the discharge and treatment of sewage, the YE4 electric motor driven submersible pump can transport sewage to designated treatment areas. Its stable operation performance ensures the continuity of the sewage treatment process.

In municipal drainage work, when encountering rainwater accumulation or sewage discharge, the combination of YE4 electric motor and submersible pump can effectively drain water, avoiding urban waterlogging and other issues. Moreover, the low noise characteristics of the YE4 electric motor also reduce noise pollution to the surrounding environment.

In terms of building water supply and drainage, whether it's the building's water supply or drainage system, the YE4 electric motor works in synergy with submersible pumps to ensure the rational distribution and normal discharge of water resources within the building. Among them, the durability of the YE4 electric motor guarantees the long-term stable operation of the water supply and drainage system.

With the development of high-end fields such as marine development, the YE4 motor can also be applied to underwater pumps working in marine environments. For example, it can be used to pump seawater on offshore platforms for purposes such as flushing, cooling, or fire extinguishing. Its double-layer insulation structure and anti-corrosion measures make it more suitable for complex environments like the ocean, giving it an advantage over traditional motors.

Conforms to the trend of diving pump development

Submersible pumps are evolving towards efficiency, intelligence, and energy conservation. The high efficiency and energy-saving properties of YE4 electric motors align with this trend. At the same time, YE4 electric motors can be combined with intelligent protection strategies. For instance, in intelligent protection systems for submersible pump motors, such as overload protection and leakage protection, YE4 electric motors can better adapt to the requirements of intelligent control, enhancing the operational safety and service life of submersible pump motors.
