YQN series submersible dredge electric motor
YQN series submersible dredge electric motor is developed for channel dredging, sand mining,marine equipment and underwater engineering.It is applied in trailing suction dredger,twisting suction dredger,sand mining ship, and special underwater equipment which is matched with underwater pump,cabin pump,sand pump,reducer, and special underwater equipment.It can work underwater or in cabins for a long period time. All of its functions
can satisfy various requirements of the above-mentioned ships,pumps and reducers.At the same time,the product has the characteristics of the structure reasonable,choose the material superior quality,install convenient and the credibility high etc.It is the perfect driving equipment of dredge industry and marine equipment When the product is used to match with converters,it has been taken full consider of the effects on the motor
created by the high-frequency harmonic of converter and the change of frequency,to insure it meet the requirements of frequency control on motor.
The product has a variety of installation forms.We can select it in accordance with the conditions
Reliability,intelligence and green efficiency are the basis principles during the product designing.And it has been
taken full consider of the requirements of complexity of motor working underwater, strong overload capacity and
high reliability. The motor has the characteristics as follow:
YQN series motor is divided into three types:dry type,inflation type and oil-filling type.It is the closed structure.The type will be selected in accordance with different working conditions. The exposed outer shell of motor is made of corrosion-resistant steel and welded to shape.All of fastening components are of high quality stainless steel.Rotor are of squirrel-cage.
In order to guarantee reliable operation,class H insulating material shall be adopted to be main insulation.
Stator slot insulation,layer insulation and impregnated paint are chosen as high-class and quality insulation,which can work normally under the condition of high temperature.The damp proof process is used when installing the whole set.
Sealing of motor contains static sealing and rotary sealing.Static sealing shall be sealed by sealing compound and sealing rings.Rotary sealing utilizes mechanical seal and oil seal to combine seal, which mechanical seal is main and oil seal is assistant. The inner extension cable is also used oil resistant rubber as cable jacket.The inner connectors are sealed by special sealing process,which can avoid water from damaged cable into motor chambers and also prevent sweating caused by cable breathing,which due to working in humid environment or long-term placement
In motor inner,there are normal over heat protective sensor,motor inner chamber water sensor,oil chamber water sensor, cable connection chamber water sensor and bearing temperature sensor.All of alarm signals shall be
Transmitted to a motor protector and a display meter in motor switch gear.According to different signals,relevant
instruction and display shall be given.
When the electric motor is applied to deep sea,it usually equip with pressure balancing devices which could make
The pressure inside and outside of the electric motor well balance automatically.
Motor can adopt reduced voltage measure to start As for large capacity, it is better to adopt soft starting or inverter
starting control to start.Elom can supply the matched switch gear.By means of inverter or diesel engine, motor
has the ability to adjust running speed.Motor fully satisfies the characteristic requirements to adjust running speed.
According to customer requirements, different sensors can be used to implement the following content of the
a.Temperature: detection of stator temperature and bearing temperature
b.Vibration: detection of displacement,speed and acceleration
c.Power supply:detection of voltage and current
d.Leakage: detection of stator water and oil chamber water
e.Speed: detection of speed
It can monitor and warn the running state of equipment through above mentioned detections. It can analyze from time to time,track running status, and provide early warning report At the same time,it can also realize remote
monitoring and management of the Internet of Things.
