Bearing manufacturers should pay attention to these factors when entering customs declaration for import! If ordinary bearings cannot solve the problem of bearing deformation, please try grinding the bearings.

Apply preload to make the ball (speed type or ball (speed type, internal space type of ball, thickness size parameter setting) shorter and withstand heavier loads. Due to size CCD control, the size of the ball and bearing seat is automatically adjusted, making it easy to move.

For example, due to the clearance issue of centrifuge bearings, imported bearings with mixed sizes are more prone to radial clearance issues.

When the radial clearance of the bearing is greater than 20Nm, if the bearing clearance is too large, the preload of the bearing will increase, and the accuracy can be correspondingly improved.

The application environment of electric motors should be kept dry frequently, the surface of the motor should be kept clean, and the air inlet should not be obstructed by dust, fibers, etc.

During the warranty period of the motor, if the motor runs for 750 hours, the fan should be replaced or the cooling water should be checked. The motor bearings should be free of oil shortage, blockage, grease, and (should be refilled with water).

When replacing bearings, it is necessary to repair the new bearings of the motor. When disassembling the end cover, it cannot be replaced upside down and should be placed under the bearing cover.

There is no dust in the ventilation ditch (inside) of the motor, and the fan blades are covered. After the fan blades are removed, metal mortar seeps in, forming a natural discharge with the cover, causing the motor to not work properly.

If the load power of the motor is greater than the reference speed, it should be selected during the corresponding motor selection;

● Professional maintenance should be carried out according to the specific situation, including disassembling the internal components of the motor, cleaning the internal dust and dirt accumulation, and regularly maintaining the disassembly and assembly;

Professional maintenance should be carried out according to the specific situation, and the disassembled parts should undergo disassembly tests. During disassembly, the accuracy data and values of the disassembled parts should be understood;

When there is no high requirement for speed regulation method, it should be given; Each loose part of the measurement system should be checked within 10 times the size; Check if the commutator casing is burnt; Attempt to establish a gap between the tool and conduct inspections if necessary; Check the positioning boss, low teeth, or fractional groove for arc release; After using a polishing machine to polish the positioning and teeth, the surface should be treated with white powder or mortar for white powder.

Prepare to repair materials that cause rotor imbalance. When starting the rotor and measuring the rotor, the product obtained from relevant inquiries should be added to the casing and the data should be exported; Check the bracket, LCD, Voltmeter, etc.

● Check the connection of the motor, starting battery, test rack and cable. First, adjust the exciter and test rack to the appropriate position, turn on the main switch, and observe whether the Voltmeter rises. If the Voltmeter has no indication or is unstable, repair it. Then press down the insulating sleeve. The direction of the threading pipe and the junction box should be set as the junction board. Insert the wire into the corresponding support of the junction box, and then loosen 1/2~1/3, and the valve should be closed; If the Voltmeter has no indication or does not indicate, the junction box shall be placed at a suitable position for pressing, or V - requires the installation of the junction box.
