How to identify a Washing Machine Carbon Brushes
It's always good to run without fire. The current is below the rating, the spring pressure is normal, the slide ring (or the commutator) is smooth, the washing machine carbon brush is smooth and smooth, and the wear is uniform, and it is sure not to fire.
The washing machine carbon brush looks at the wire fastness, the spring is strong, the flexibility is better, the washing machine carbon brush surface is not rough and light, weighing weight is more than the ordinary washing machine carbon brush has the component. It has high density, wear-resisting and long life.
Washing machine the stand or fall of carbon brush should model is correct, specification, as long as the model, it is the good washing machine carbon brush, can't see the weight, wear resistant to bad rotor, washing machine to buy carbon brush should offer production vendors models, if no, provide the carbon brush samples, such as washing machines.
The function of the Washing Machine Carbon Brushes in the motor is to change the current direction of dc motor and ac motor. The dc motor is to change the conductive coil of the rotor, thus changing the rotor magnetic pole. It changes the motor's motion. The carbon brush is used for washing machine motor commutator or slip rings, as export import current sliding contact, its conductive, thermal conductivity and good lubrication performance, and has certain mechanical strength and commutation spark instincts. Almost all brushless motors use the washer carbon brush, which is an important component of the brush motor.
The carbon brush of motor washing machine is suitable for all kinds of motor, generator, wheel shaft machine, with good commutation performance and long service life. Washing machine motor carbon brush is used for motor commutator or slip rings, as export import current sliding contact, its conductive, thermal conductivity and good lubrication performance, and has certain mechanical strength and commutation spark instincts. Almost all electric motors use the washing machine carbon brush, which is an important component of the motor. It is widely applicable to all kinds of ac and dc generators, synchronous motors, battery dc motors, crane motors, electric welding machines and so on. With the development of science and technology, the types of motor and working conditions of the use of more and more diversified, so need to have different grades of brush to satisfy these requirements, therefore, the types of brush has more and more with the development of motor industry.
A very important basis to determine the quality of the Washing Machine Carbon Brushes is the wear rate of the washing machine. The smaller the wear rate of a Washing Machine Carbon Brushes, the longer its service life will be. Also, because the wear rate of the Washing Machine Carbon Brushes is smaller, the operation cost of related equipment will be smaller and the operating costs are very low
1, can the finish on the surface of the slip ring carbon brush wear as a washing machine: if the finish on the surface of the slip ring is high, because of its generated by the friction coefficient is relatively small, so the washing machine carbon brush wear rate can be decreased. In addition, we all know, there is a layer of oxide film on the surface of the slip ring, its main function is to reduce the slip ring and a washing machine, the friction coefficient between the Washing Machine Carbon Brushes to reduce the carbon brush wear degree.
2, the pressure of the pressure spring also affects the wear degree of washing machine carbon brush: moderate pressure spring pressure must be adjusted, because if the spring pressure is too large, will increase the mechanical wear of carbon brushes the washing machine; If the pressure spring pressure is too small, although the friction between the washing machine carbon brush and the sliding ring is smaller, it is easy to create the spark of contact.
3. The current will also affect the wear and tear of the Washing Machine Carbon Brushes. Under normal circumstances, the graphite of washing machine washing machine in the anode carbon brush carbon brush through the current washing machine than the cathode carbon brush through the current is relatively larger, casual can cause the positive washing machine carbon brush wear degree than negative wear of carbon brushes the washing machine. And the positive slip ring wear also than negative slip ring, so every time the unit overhaul, we can adjust the washing machine by positive and negative polarity cable carbon brush head to achieve the purpose of delaying wear.
4. The Washing Machine Carbon Brushes can also affect the wear and tear of the washing machine. Different washing machine carbon brush manufacturer and different washing machine carbon brush model its composition and construction are different, so the wear rate of washing machine carbon brush also is not same. So we recommend that customers choose the same carbon brush as the same as possible, because it reduces the amount of wear and tear in the washing machine that is caused by the product model.
