Summary of Maintenance and Protection of Power Tools Carbon Brush and Collector Ring
The collector ring should be kept clean, roughness round the road Ra0.80μm, eccentricity error can not exceed 0.04mm. Run time to adjust the generator Power Tools Carbon Brush the flow and temperature, run not check the generator 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 improper handling caused by secondary disasters.
In order to adjust and check the Power Tools Carbon Brush spring pressure in a timely manner, keep the spring pressure even too tight or loose, adjust the gap between the Power Tools Carbon Brush and the brush box, make the Power Tools Carbon Brush flexible in the brush box Astringent phenomenon. Accurately adjust the brush box and the distance between the collector ring should be maintained between 2 ~ 3mm. The distance is too small, the cartridge is easy to wear the surface of the collector ring; the distance is too large to cause the Power Tools Carbon Brush to swing or run.
Power Tools Carbon Brush The role of working in oil wells: Power Tools Carbon Brush is the device that transfers energy or signals between a fixed part of a motor or generator or other rotating machine, which is typically a pure carbon plus coagulant Made, the appearance is generally 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 The signal is sent from the rotating part (cable drum of the wire) to the ground instrument.
Power Tools Carbon Brush looks like a pencil-like rubber band, the top of the wire leads. The volume is very small. The circular bearing can be slid in the long bar. The Power Tools Carbon Brush is constructed to hold the Power Tools Carbon Brush in the specified position with the appropriate pressure to hold the Power Tools Carbon Brush to prevent the Power Tools Carbon Brush , A frame portion connecting the brush box and the pressing portion, and a fixing portion for fixing the brush holder to the motor. Power Tools Carbon Brush mainly uses bronze castings, aluminum castings and other synthetic materials. Requirements Brush itself has good mechanical strength, processing performance, corrosion resistance, heat dissipation and conductivity.
When the Power Tools Carbon Brush is burned, wrap it with a fine gauze on the commutator, and gently clean the commutator slot with a blade, and then the commutator is wrapped in gauze. Polished. Do not let the motor commutator beating, Power Tools Carbon Brush will not fire, do not fire the heat will be very small Power Tools Carbon Brush spring will not burn soft, will not produce a vicious cycle.
Power Tools Carbon Brush looks fast, spring is strong, flexible, Power Tools Carbon Brush surface is not rough and bright, weigh the weight than the average Power Tools Carbon Brush has the weight on the line. Indicating that it is high density, wear resistance, long life. When the Power Tools Carbon Brush is burned, wrap it with a fine gauze on the commutator, and gently clean the commutator slot with a blade, and then the commutator is wrapped in gauze. Polished. This will be good, but if the quality of the motor itself is a problem, it is only the replacement of the motor, and now the market cut corners of the machine too much. A: slightly increase the pressure of the Power Tools Carbon Brush spring, to ensure that the motor bearing the degree of precision, do not let the motor commutator beating, Power Tools Carbon Brush will not fire, do not fire the heat will be very small The Power Tools Carbon Brush spring does not burn soft and does not produce a vicious circle. As long as your machine manufacturing precision is high enough, with the time will be long enough.
The brush is placed on the center line of the pole, but the Power Tools Carbon Brush should be placed on the geometric centerline of the motor. If the brush deviates from the geometric centerline, the magnetic field generated by the rotor windings (armature windings) Which affects the magnetic field generated by the stator winding (excitation winding), that is, the reaction of the direct axis and the armature reaction, so that the synthetic magnetic field in the space is distorted, which affects the normal operation of the motor and reduces the efficiency. So the brush should be placed on the geometric centerline. Where the geometric centerline lies in the stator magnetic field of the magnetic pole center line, the stator pole has several pairs, the corresponding geometric center line there are several.
