Causes of noise from electric flatcars
2022-05-16
1. Common faults of low-voltage equipment: abnormal noise is generated in the control circuit generally emits a "hum" noise, most of which is a common fault of the AC contactor (such as AC contactor circuit breaker poor contact phenomenon. Rated voltage does not meet. Magnetic core is stuck these), solve the common fault AC contactor to carry out maintenance, can not repair when the need to remove and replace, after the solution, the noise independent clear.
2. Common faults of electric flatbed car: immediately shut down, check whether the electric flat car is single-phase electric operation, or rolling bearing destruction. Output shaft pivot skew and "sweeping" and other common failures, this is to make the electric flatbed truck have abnormal sound, not the same common fault sound parts and how much and sound not the same, single-phase electricity running, all electric flatbed truck out of the regularity of the strong and weak "buzzing sound "sound; and rolling bearing damage, will be in the rolling bearing around, out with the "Gaden - Gaden" "buzzing" sound; and output pivot skew, or electric flatbed car light sweep, all electric flatbed car out A very high "buzzing" sound, often accompanied by a sharp, harsh sound. In short, should be based on the noise of the different, find common faults, carry out one-by-one repair, repair electric flatbed truck all normal characteristics, when the electric flatbed truck common faults are not dealt with, the application of electric flatbed truck is strictly prohibited.

3. reducer common fault: shut down the machine to check, confirm the reducer of the reducer or rolling bearing in the application is not added grease, the application is not regularly replaced grease, such as not according to the requirements of wetting, reducer will not only form too high "humming" sound, but also continue too much damage or destruction of the transmission gear and rolling bearings.
