Fast shutter doors Instructions three (maintenance and repair)
      ZHEJIANG DULUN ENERGY SAVING TECHNOLOGY CO., LTD. is a professional Continental shutter doors, shutter doors sheet, aluminum manufacturers.
       Length of life is not just the quality of the door fast, everyday proper use and maintenance is also very important.
Periodic inspection:
      Periodically review the door rail, doors without deformation, jamming phenomenon, the operation button is good, whether the button box door can be locked. The shutter doors electrical control box indicating signal is normal, the box for damage. Door opening button, press the top (or bottom) button, shutter doors should rise or fall, if the shutter doors up and down the elevator button operation and is not the same, you must immediately stop, adjust the power supply before re-entry program after the operation. In the button operation rise (or fall) process, the operator is prohibited to leave the scene, while the operation should pay close attention to shutter doors rise (or fall) is able to automatically stop after a certain location. If the shutter doors rise forthcoming rail (or fall to the ground already) is still not stop, it must be limiting device repair (adjustment) to normal before re-operation.


Fast door motor maintenance:

      Maintenance process: cleaning rotor - replace brushes or other components - F grade vacuum pressure impregnation - drying - balancing school.
1, the use of the environment should be kept dry, the surface of the motor should be kept clean, the air inlet should not be affected by dust, fiber and other obstacles.
2, when the continuous operation of the motor thermal protection, should identify the fault from the motor or overload protection devices or setting value is too low, after elimination of the fault can be put into operation.
3, should ensure that the motor well lubricated during operation. General motors run about 5000 hours, which should supplement or replace the grease, running or overheating found bearing lubrication deterioration, in time for hydraulic grease. When replacing the grease, you should remove the old oil, gasoline and cleaning bearings and bearing cap fuel tank, and then the cavity ZL-3 lithium grease filling between the bearing inner and outer rings of 1/2 (2-pole) and 2/3 (for 4,6,8 pole).
4, when the end of life of the bearing, vibration and noise will significantly increase the motor running, check the bearing radial clearance reaches the following values, which should replace the bearings.
5, when removing the motor from the shaft end or extended end of the rotor can be removed. If there is no need to remove the fan, or remove the rotor from non-drive end is more convenient, when removal of the rotor from the stator, should prevent damage to the stator windings or insulation.
6, must write down the primary winding of the form, size and number of turns, wire gauge and other replacement of winding, when the loss of these data, the manufacturer should be obtained, free to change the original design of the winding, often an electric motor or several performance worse, even unusable.
