Fan does not turn maintenance

1, often caused by bathroom window fan blades do not turn the reasons, are poor maintenance problems. If you turn off the power after the hand to move the fan blade rotation stiffness, you should use some lubricants into the shaft, so that it can be lubricated, it will not affect the motive drag the fan.
2, for the wear caused by the bathroom ceiling fans does not rotate, the most simple or replacement parts, especially the sleeve, if easy to burn after wear and tear.
3, if the capacitance becomes smaller cause the bathroom ventilating fans does not turn, you can remove the capacitor, for a new type of capacitor, the proposed choice than the original capacitor 20%, there will be a better rotation effect.
4, shaft axial gap is too large problem, you can choose to remove the motor after the adjustment of gasket. But remember that when the motor is installed back, pay attention to the rotor must be concentric with the bearing, lubrication screw slowly twist the twist, and finally knock on the shaft with a wooden shaft to ensure that it concentric.
5, if it is because of electrical failure, you can check the wiring of the lines, and sometimes wire damage, etc., can repair the problem.

How to use and maintain the correct fan?

1. Before using the instructions should be read in detail, fully grasp the structure of the electric room fan, performance and installation, use and maintenance methods and precautions.
2. Desktop, floor-mounted fans must use a safety grounding cable three-pin plugs and sockets; ceiling fans should be installed in the ceiling of the higher position, you can not install the ground.
3. Fan blades are important components, whether in the installation, removal, scrub or use, must strengthen the protection, to prevent deformation.
4. Operation of the function switch, button, knob, the action can not be too fast, too fast, can not press two keys at the same time.
5. Ceiling fan speed control knob should be slow to rotate in sequence, should not spin in the stall position, or easy to make ceiling fan fever, burn machine.
6. Fan with a long time later, the leaves of the following is easy to stain a lot of dust. This is the bathroom window fans at work, because the fan and the air friction between the fan leaves the static, charged objects can attract the nature of small objects, which can absorb the indoor floating small dust caused. The fan of the oil or fouling, should be promptly removed. Do not wipe with gasoline or strong lye, so as not to damage the surface paint components function.
7. If the fan in the course of the use of hot, abnormal Jiao Wei, shaking his head is not working, slow speed and other failures, do not continue to use, should promptly cut off the power maintenance.
8. Collect the electric stand fans should be completely removed before the surface of oil, fouling, and wipe with a dry soft cloth, and then wrapped with kraft paper or clean cloth. Store the location should be dry and ventilated to avoid extrusion.

The fan of the purchase skills

1. Look at random files Each fan's random file includes the instruction manual, product certification, electrical circuit diagram and packing list, the purchase should be in accordance with the packing list inventory, check the number and quality of parts.
2. Look at the screen and the exhaust window fans is obvious deformation in the assembly of the fan fan cover, with a pen pointing to the highest point of a fan, slowly move the fan, the other few leaves corresponding to the tip of the pen The distance should be very close, and then turn the fan, pay attention to observe whether the rotation is light and flexible, and can stop at any position.
3. To see whether the control mechanism is flexible control mechanism including speed control switch, timing knob, shaking his head switch, lighting switch, etc., these control agencies should be flexible operation, reliable contact. On the speed control, do not allow two blocks at the same time connected or a block can not go on the phenomenon. Press the stop button, the speed of the key should be normal reset.
4. Look at the activities of some of the performance fan fan head overlooking the angle of the operation of flexible, tight lock, adjust to the maximum angle or shaking his head to the final position, the net cover are not collided with the fan pillars. Fan operation, the stability is better, can not be dumped, shaking his head should not be less than 60-80 degrees.
5. Start performance performance Start performance is an important fan of quality indicators. Inspection, should be transferred in the slow speed, and the power supply rated voltage of 85%, that is, with a voltage regulator to 220 volts to 187 volts to start the fan, electric industrial fans should be able to start from the static, and normal operation, The shorter the time required for a fan to start from normal operation, the better the start-up performance of the fan motor.
6. To see the operation and speed performance power after the shaking his head switch back and forth several times to check whether the failure or assembly too tight, in this process, the fan mechanical transmission part should not have abnormal noise. Fan in high, medium and low speed operation, the motor and fan should be smooth, small vibration, low noise. Fan shaking his head, shut down should be agile, no intermittent, stagnation and jitter phenomenon, the block speed difference should be obvious, the air angle the greater the better. When the fan stops, the shaft axial clearance does not exceed 0.5 cm, the gap is too large, the operation will cause axial movement and impact sound.
7. to see if the leakage of electric power, if the hand touched a strong hemp inductance, test with a pen test, test pen will be light display, can determine the shell leakage, can not be used.
8. to see the continuous operation of the fan performance Fan continuous operation after 2 hours, if the nose shell surface hot, indicating that the temperature is too high, can not be selected. Under normal circumstances, the nose shell surface temperature below 50 ℃, there will be no very hot feeling.

Five-leaf bath ventilator fans, by the Northwestern Polytechnic University aerodynamics expert Professor Sidko use the aircraft wings, propeller principle, to explore a set of the best fan blade bend, sweep angle, the most favorable center of gravity line shape and Blade plane shape. Using these fan design techniques, the design of the fan has a significant high efficiency, low noise characteristics.
As the "cut" the wind is more uniform, the use of "five leaves" of the fan not only brings a mute effect, from the comfort point of view also more choices. Fan fan can be achieved when a wider range of multi-block adjustment. Most of the "three leaf fan" is basically a third block of wind regulation, "five leaf heater with fans" can be more than a block.
Especially in the lower operation of the block, the air is not very violent, you can avoid the fan blowing easy to cool the problem, and from the energy point of view is still very good. It is understood that the United States, "five leaves mute" electric fans as an example, energy efficiency standards can be achieved 1 16 talent platform fan air volume than the national standard increased by 27%, noise than the national standard reduced 15.8%; click power is also reduced 11.4%, energy efficiency ratio increased by 24%.

The shape and principle of the oil and oil are similar to those of the parents. It is the purpose of heating and heating by heating the heating oil in the machine. The structure of the oil is similar to that of the radiator. Therefore, the relationship between the number of electric heaters for home plates and the heating effect Very close.
