Summary of maintenance and protection of Power Tools Carbon Brush and collecting ring
Power Tools Carbon Brush and the collection ring protection and protection Summary: collector ring should be kept clean, roughness Roadway Ra0.80μm, eccentricity error can not exceed 0.04mm. Operation to adjust the generator Power Tools Carbon Brush flow And the temperature, the operation can not check the generator are the flow and temperature, maintenance personnel check the daily flow and temperature, found abnormal and failed to deal with in time, stressed that when there is equal flow when the correct way to deal with, to avoid processing methods Improperly causing secondary disasters.
    The operation should be timely to adjust and check the Power Tools Carbon Brush spring pressure, so that spring pressure even no excessive or too loose phenomenon, adjust the Power Tools Carbon Brush and brush between the gap, so that the Power Tools Carbon Brush in the brush box activities flexible Astringent phenomenon. Accurately adjust the distance between the brush box and the collector ring should be kept between 2 ~ 3mm. The distance is too small, the cartridge easy to wear the surface of the collector ring; distance is too large, easy to cause the Power Tools Carbon Brush swing or beating.
     The role of the carbon brush in the work of the oil mine: the Power Tools Carbon Brush is the device that transfers energy or signals between the fixed part of the motor or generator or other rotating machine, which is usually a pure carbon plus coagulant Made, the appearance is generally box, stuck in the metal bracket, there is a spring to press it on the shaft, such as oil drilling is completed, the need for testing, it is necessary to put the instrument from the wellbore down, that is, through the Power Tools Carbon Brush The signal is sent from the rotating part (cable drum of the outer wire) to the ground instrument.
     The lookout of the Power Tools Carbon Brush is like a rubber band with a pencil pencil. The volume is very small. The circular bearing can be slid in the large bar.With the structure of the Power Tools Carbon Brush is to keep the brush part of the Power Tools Carbon Brush in the prescribed position, press the Power Tools Carbon Brush with the appropriate pressure to prevent the Power Tools Carbon Brush vibration , A frame portion connecting the brush box and the pressing portion, and a fixing portion for fixing the brush holder to the motor. Electric tools are mainly used bronze castings, aluminum castings and other synthetic materials. Requirements Brush itself has good mechanical strength, processing performance, corrosion resistance, thermal performance and electrical conductivity.
     Power tools Carbon brush electrode situation and description: Power Tools Carbon Brush is the motor or generator or other rotating machinery and the rotating part of the fixed part of the transfer of energy or signal between the device, it is generally made of pure carbon coagulation agent Type is usually a box, stuck in the metal bracket, there is a spring to press it on the shaft, such as oil drilling is completed, the need for testing, it is necessary to put the instrument from the wellbore down, that is, through the Power Tools Carbon Brush from the signal Part (the cable drum of the outer wire) is sent to the ground instrument.
 The lookout of the Power Tools Carbon Brush is like a rubber band with a pencil pencil. The volume is very small. Electric tools Carbon brushes are used as a sliding contact and are widely used in many electrical equipment. Product materials are mainly electro-graphite, dipped in graphite, metal (including copper, silver) graphite.
Power tools Carbon brush for a variety of motors, generators, wheel machine. Has a good commutation performance, long service life.
The Power Tools Carbon Brush is used for the commutator or slip ring of the motor as a sliding contact body for deriving the incoming current. It has good electrical conductivity, thermal conductivity and lubrication performance, and has a certain mechanical strength and commutation spark. Almost all motors use electric tools for carbon brushes, which are important components of the motor. Widely used in a variety of AC and DC generators, synchronous motors, battery DC motor, crane motor assembly ring, all types of welding machines and so on.
