SIMO YKK electric motor 1000kw adopts fully enclosed air-air cooler, to improve the heat dissipation performance and temperature rise of the motor. It is cooled by the internal air (motor hot air) of the heat exchanger (air-to-air cooler). The device itself is cooled by the external cooling air flowing through the heat exchanger (air-air cooler). The equipment consists of an air-air cooler and an external fan mounted on the motor shaft or an air-air cooler and an axial fan. Air-to-air coolers are usually manufactured by professional manufacturers, and the amount of heat and temperature difference to be exchanged per unit time must be determined when the motor is designed.
Three hidden plates are arranged in the cooler to guide the flow of the internal air path. The partition in the middle is at the same distance from the partitions on both sides. The motor rotates through the rotor to drive the internal air path to circulate. The internal wind from the motor flows into the cooler from bottom to top along the radial direction. Under the action of the partition, it flows through the tube bundle in two ways to the upper space of the cooler, and then turns to flow downwards and flows through the tube bundle. In this way, the heat in the motor is transferred to the heat exchange tube through the inner air duct, and then transferred to the outer air duct through the heat exchange tube. The cooled motor internal wind flows out of the cooler radially from the left and right outlets and flows into the motor. The outside wind flows axially in the heat exchange tube, flows in from one end and flows out from the other end.
Since the stator and rotor cores of SIMO YKK electric motor 1000kw have radial and axial ventilation channels, according to the direction of the cooling air flow inside the motor, the internal ventilation of the motor can be divided into two types: radial ventilation and mixed ventilation. The mixed ventilation system generally belongs to the series air path, the air path is long, the wind resistance is high, and the wind pressure drop is large. It is necessary to install a large fan at one end to increase the ventilation rate, but it is likely to cause the following adverse consequences:
1. Increased fan loss;
2. The cross-sectional width of the wind path at both ends of the core is asymmetrical;
3. The minimum area of the ventilation duct is small and the temperature difference between the two ends of the iron core is large.
Radial ventilation generally divides the wind resistance of the series air path into two, and then connects them in parallel to greatly reduce the wind resistance, which has the following advantages;
1. Make full use of the ventilation slots and rotor webs of the rotor that can generate wind pressure to generate wind pressure;
2. It has the characteristics of low turning wind resistance, short wind path, small wind pressure drop and low fan loss;
3. There is a good energy-saving and consumption-reducing effect.
SIMO YKK electric motor 1000kw maintenance;
Regular inspection to see if there are abnormal sounds and vibrations during operation; if the rotating parts are overheated or loose.
Regular maintenance: check the tightness of the parts and components thoroughly. Check the radial clearance between the fan tube and the impeller; the angle of the blades and the bounce of the blades along the axial direction of the fan. Remove the oil on the surface of the fan blades.
Precautions for use: The use angle of the fan should not exceed the specified angle adjustment range to prevent the motor from overloading; When the motor is overhauled and replaced, must pay attention to wiring phase, and the fan impeller should be rotated clockwise when viewed from above.
