Prevent failures that are prone to occur in the work of metal balers

There are two types of three-phase asynchronous motors for hydraulic metal balers: direct start and step-down start.Direct start is a simple, reliable and economical start-up method, but the motor start-up current is 4/7 times the rated current.On the one hand, excessive start-up current will cause the voltage of the power grid to drop significantly, which directly affects the normal operation of other motors and electrical equipment in the same network.On the other hand, frequent start-up of the motor can cause serious heat generation, accelerate the aging of the coil, and shorten the service life of the motor.Only small-capacity motors are allowed to start directly.Due to the large starting current, large-capacity cage asynchronous motors usually use step-down start.Step-down start-up refers to the start-up of the stator winding of the motor by appropriately reducing the voltage of the starting equipment and then applying it.After the motor starts, the voltage returns to the rated value of normal operation.Since the current decreases as the voltage decreases, the starting current passes through the buck.

In order to prevent the metal baler from being prone to failure during work, in order to further check the damage of the internal parts of the metal baler, and remove the damaged parts for repair or replacement.This contributes to the efficiency and service life of the metal baler.Strictly abide by the correct folding and unloading method of the metal baler, and use appropriate disassembly tools correctly to avoid serious damage to the metal baler. It is strictly prohibited to work on the working surface of the parts.If you need to strike, you can use a copper or plumb hammer, or you can add a soft cushion between the work object and the hammer. Do not use measuring tools or contusion knives instead of hammers, use gun heads instead of hammers, and chisels instead of wrenches.From the table to the inside, from the assembly to the component., Then go to the parts, disassemble step by step, and check while disassembling.The parts of the metal baler equipment after disassembly should be placed in the wooden frame and wooden box in order to prevent the parts from being scattered, damaged or rusted due to moisture, so as to avoid confusion during assembly.
