Electric drills, electric saws and so on. Under what circumstances should carbon brushes be used?
Matters needing attentionBrush brush rack loaded on the surface, should pay attention to the direction, will hold against the contact surface is too small, weak power or power.Brush lead wire is sheathed with an insulating tube, should be installed in the insulating brush frame; lead wire is bare copper wire, should be installed in the ground brush frame.3. brush brush rack in the internal free landing, such as issuing phenomenon, should remove the excess.4. should brush brush spring pressure in the middle, to prevent uneven force of eccentric wear.The contact area of 5. carbon brush and the commutator, all contact surfaces should be not less than 3/4, the carbon brush is not oil.
Is the energy transfer device or signal between motor or generator or other rotating machinery of the fixed part and the rotating part, it is generally made of pure carbon coagulant, the general shape is square, stuck in the metal bracket, which has spring pressed it on the shaft, such as oil drilling is completed, it will need to be tested, to put down the instrument from the wellbore, is through the brush signal from the rotating part (cable drum outsourcing wire to ground equipment). The carbon brush looks a bit like the eraser bar of a pencil, with a lead on it. Size is large or small. Carbon brush, as a sliding contact, has been widely used in many electrical equipment. The main products are anodized graphite, impregnated graphite, metal (copper, silver) graphite.
Brush (Carbon brush) also known as brush, a sliding contact, is widely used in many electrical equipment. Carbon brushes are mainly used in products such as graphite, impregnated graphite, and metal (including copper, silver) graphite. The carbon brush is the energy transfer device or signal between motor or generator or other rotating machinery of the fixed part and the rotating part, it is generally made of pure carbon coagulant, the general shape is square, stuck in the metal bracket, which has spring pressed it on the shaft, when the rotation of the motor, the power through the change which is delivered to the coil, as its main components are carbon, known as carbon brush, it is easy to wear. Regular replacement, cleaning and carbon deposition shall be maintained.
A carbon brush is used whenever a point drill or an electric saw is used. It is a device that transmits energy or signals between a stationary part of a motor or other generator or other rotating machine;If the power tools are stationary or not turned, they should be changed basically, unless the motor is burned;
