Why did the rotary evaporator gear motor malfunction? Rotary evaporator manufacturers will answer you.

The rotary evaporator rotates under constant temperature heating and under negative pressure to form a film, and then is efficiently evaporated and then cooled to recover the solvent. It is an ideal instrument for laboratory distillation extraction, material crystallization and solvent separation.Yesterday we talked about the precautions of using the rotary .Also as the main parts of the rotary evaporator,gear motor is the essential tools to control the flask rotation speed.If there is a fault in the use of the reduction motor, it will affect the efficiency of the experiment.Today, as a manufacturer of rotary evaporator, Henan Lanphan science and technology is here to answer your questions about the possible reasons for the failure of the rotary evaporator gear motor.

The reasons for the rotary evaporator gear motor malfunction are as follows:

1、Rotary evaporator geared motors have been subjected to excessive load for a long period of time, causing the temperature to rise too high and damage the insulation, shortening the service life of the geared motor.

2、Rotating speed matching principle refers to the gear motor and the manufacturing machine are running in the setting speed in the same Same transmission mode.

3、Keep the components of the geared motor clean, ensure that the assembly of the end cover, bearings, etc. is reasonable, and do not perform brutal construction to prevent the corresponding components from being deformed by the force-decelerating motor.

4、Bearing damage is a common fault in the operation of geared motors.Replace the bearing again . If the motor end cover is nested, the interference is large or the ellipticity exceeds the standard, causing the bearing ball clearance to be too small or uneven, resulting in an increase in the friction force when the bearing is running, and the temperature rises sharply or even burns the instrument.

5、The bearing chamber is not clean or the grease added is not clean.For example, the tiny rigid material in the bearing cage is not completely cleaned, or the bearing raceway is damaged during operation, causing the temperature rise to be too high and burn the bearing.

6、The operating temperature of the geared motor of the rotary evaporator is too high, and the bearing is not filled with grease in time to cause the bearing to be short of oil or even burned.

7、The bearing itself has manufacturing quality problem such as Inflexibility of rotation, groove rusty spot,excessive clearance,holder deform etc.

8、When the running condition of the bearing is not good, the vibration and noise of the geared motor will increase significantly. When checking the radial clearance of the bearing, please replace the bearing.

9、The rotary evaporator does not operate for a long period of time, causing the grease to deteriorate, while the bearing is rusted but not repaired.

10、When the rotary evaporator motor has vibration, it should be distinguished whether it is caused by the geared motor itself or the transmission is bad, or it is transmitted by the mechanical load end, and then it is excluded according to the specific situation.
