Liyuan 6inch Submersible Motors Manufacturer

Liyuan Submersible Motors Manufacturer is a special motor used to drive submersible pump, which is widely used in agricultural irrigation, industrial water supply and drainage and water supply system. 6-inch submersible motor is a medium-sized submersible motor, usually used with 6-inch submersible pump, suitable for deep Wells, rivers, lakes and other water source extraction. Here are some key points about the 6-inch submersible motor:

1. Structure and composition

The 6-inch submersible motor is composed of stator, rotor, bearing, mechanical seal, cable and shell. Its main feature is that it has god sealing and can work underwater for a long time without being eroded by water. Usually the shell is made of corrosion resistant materials such as stainless steel to ensure the service life in different water quality environments.

• Stator: The stator is embedded with copper coils to generate a magnetic field and drive the rotor to rotate.

• Rotor: It interacts with the stator to produce rotating motion and directly drives the impeller of the submersible pump.

• Bearing and mechanical seal: ensure the smooth and waterproof performance of the motor in high humidity environment. A high quality sealing system prevents water from entering the motor and extends its service life.

Second, the working principle

The working principle of the submersible motor is similar to that of the conventional motor, based on the principle of electromagnetic induction. When the motor is powered on, the stator coil generates a rotating magnetic field, which drives the rotor to rotate, and the rotor shaft is connected to the impeller of the pump, which makes the impeller rotate at high speed, so that the water is extracted from the well or water body.

3. Technical parameters

The specific parameters of the 6-inch submersible motor will vary according to different manufacturers and the use environment, but usually include the following important parameters:

• Rated power: The power range is generally between 2.2kW and 37kW, and the user can choose the right power motor according to the actual pumping demand.

• Rated voltage: 380V three-phase AC is usually used, and 220V single-phase power is also used in some occasions.

• Rated frequency: 50Hz or 60Hz, depending on regional power supply standards.

• Speed: Generally about 2850rpm, but there are also variable speed models adjusted according to actual needs.

• Efficiency: high-quality 6-inch submersible motors usually have a high energy conversion rate and significant energy saving effect.

4. Advantages and applications

The 6-inch submersible motor has the following significant advantages:

1. High efficiency and energy saving: High efficiency motor design can reduce the consumption of electric energy, and can maintain high efficiency operation within a large range of load changes.

2. Strong durability: submersible motors generally use corrosion-resistant materials, which are suitable for various water quality environments, especially acidic or alkaline water bodies.

3. Easy installation: Compared with traditional pumps, submersible motors are directly placed underwater, without complex ground pumping stations and equipment, which greatly saves installation space.

4. Stable operation: Because the motor runs under water, the noise is small, the cooling effect is good, and it can work continuously for a long time.

6 inch submersible motor has a wide range of applications in agricultural irrigation, drinking water extraction, municipal drainage and industrial water treatment. For example, in farmland irrigation, the 6-inch submersible motor can effectively raise groundwater to meet the needs of crop growth; In the industrial sector, submersible motors can also be used to extract cooling water or treat sewage.

Maintenance and maintenance

Although the 6-inch submersible motor is designed to work for long hours, daily maintenance and maintenance is still crucial. Here are some common maintenance measures:

1. Check the motor cable regularly: ensure that the cable is not aging or damaged, to avoid damage to the motor or leakage.

2. Monitor the working current of the motor: check the working current of the motor regularly to prevent the motor from overload or idling operation.

3. Check the tightness: replace the mechanical seal and bearing regularly to ensure the sealing performance of the motor and prevent water from entering the motor and causing failure.

4. Avoid frequent start: the submersible motor is not suitable for frequent start, and should wait at least 3 minutes after each stop before restarting to avoid damage to the motor.

conclusion

With its high efficiency, durability and wide adaptability, the 6-inch submersible motor has played an important role in various hydraulic engineering and industrial applications. Reasonable selection, installation and maintenance of submersible motors can not only effectively improve work efficiency, but also extend the service life of equipment and reduce operating costs.
