Washing Machine Carbon Brushes daily maintenance recommendations
one. Maintenance time recommended every three months on the key components of the regulator and the Washing Machine Carbon Brushes to do a shutdown check maintenance. two. Maintenance method to check the Washing Machine Carbon Brushes holder is loose, whether the Washing Machine Carbon Brushes in the same plane, the same line, the contact is good, any situation must be replaced in time, otherwise, will affect the normal operation of the regulator and life. If you find the Washing Machine Carbon Brushes wear too fast, check the column regulator coil is smooth, whether there is a floating point; load current is too large.
Washing Machine Carbon Brushes use precautions
 1, in order to protect the normal operation of the motor, the correct choice of Washing Machine Carbon Brushes model is very important, because the manufacture of Washing Machine Carbon Brushes when the choice of raw materials and processes are different, its technical performance is also different. Therefore, in the choice of Washing Machine Carbon Brushes, should be taken into account the performance of Washing Machine Carbon Brushes and motor Washing Machine Carbon Brushes technical requirements. Washing Machine Carbon Brushes use performance good mark should be:
(1) in the commutator or collector ring surface can quickly form a layer of uniform. Moderate and stable oxide film.
(2) Washing Machine Carbon Brushes long life does not wear commutator or collector ring.
(3) Washing Machine Carbon Brushes has a good commutation and current collection performance, so that the spark is suppressed within the allowable range, and the energy loss is small.
(4) Washing Machine Carbon Brushes operation, but hot, low noise, reliable assembly, no damage.
2, Washing Machine Carbon Brushes into the brush to ensure that the upper and lower free to move, Washing Machine Carbon Brushes and brush the gap between the wall should be between 0.1-0.3 mm, so that the Washing Machine Carbon Brushes card in the brush or because of the gap is too large swing. Brush the lower edge of the brush from the surface of the commutator should be kept at about 2 mm. Such as the distance is too small, brush easy to touch the commutator, the distance is too large, Washing Machine Carbon Brushes easy to cause damage.
3, in the same motor, in principle, should use the same type of Washing Machine Carbon Brushes, but for the individual for the special difficulties of large and medium-sized motor, can be used Gemini Washing Machine Carbon Brushes, sliding into the edge of the use of good lubrication, The use of suppression of spark ability of the Washing Machine Carbon Brushes. Thus improving the operation of the motor.
4, Washing Machine Carbon Brushes wear to a certain extent you need to replace the new Washing Machine Carbon Brushes, Washing Machine Carbon Brushes should be all updated, if the old and new Washing Machine Carbon Brushes mix, there may be uneven distribution of current phenomenon. For large units, the replacement of the Washing Machine Carbon Brushes is bound to affect the production, so you can use non-stop, each change 20% of the Washing Machine Carbon Brushes (that is, each motor of each brush pole 20%), each time interval of 1 -2 weeks, to be run and then gradually replace the rest of the Washing Machine Carbon Brushes to ensure the normal operation of the unit.
5, in order to make the Washing Machine Carbon Brushes and commutator (or collector ring) good contact, the new Washing Machine Carbon Brushes should be grinding radian, grinding radian generally on the motor. Place a thin glass of sandpaper between the carbon brush of the washing machine and the commutator (or collector ring). Under normal spring pressure, grind the carbon brush of the washing machine in the direction of rotation of the armature. The sandpaper should be attached to the commutator (or Collecting ring), until the Washing Machine Carbon Brushes arc surface coincidence, and then, lift the Washing Machine Carbon Brushes, remove the sandpaper, with compressed air blowing and grinding dust, and then wipe clean with a soft cloth. Grinding Washing Machine Carbon Brushes should not use emery paper, to prevent the diamond particles embedded in the commutator slot, the motor running, scrape the Washing Machine Carbon Brushes and commutator surface. After grinding, the motor first 20% -30% of the load running a small number
, So that the Washing Machine Carbon Brushes and commutator (or collecting ring) run and establish a uniform oxide film. And then gradually increase the current to the rated load.
6, applied to the same motor Each Washing Machine Carbon Brushes unit pressure should strive to be uniform, so as to avoid uneven distribution of current lead to individual Washing Machine Carbon Brushes overheating or spark. Washing Machine Carbon Brushes unit pressure should be "Washing Machine Carbon Brushes technical performance table" in the "working conditions" column recommended pressure choice. For higher speed motor or motor under the conditions of vibration, should be appropriate to improve its unit pressure to ensure that the Washing Machine Carbon Brushes normal work. For example: traction motor Washing Machine Carbon Brushes unit pressure is 0.4-0.6kgf / cm2. Usually, the Washing Machine Carbon Brushes unit pressure is too high, so that Washing Machine Carbon Brushes wear; unit pressure is too small, contact instability, prone to mechanical sparks.
