Constant temperature magnetic stirrer has been widely used, but only limited to the research and development, the level of the small, people often produces illusion to magnetic stirrer, think of the magnetic stirrer is weaker, small power, cannot be used for big volume, as well as the dead Angle, online cleaning (CIP) and online sterilization (SIP), etc., however, this view had overthrown in real applications. At present, the magnetic agitator can be zui large and suitable for 40t water agitator, or even larger, and there are many kinds of applications. In terms of structure, the magnetic agitator generally consists of a rotating head with a negative bearing. Yang bearing, tank bottom welding plate, motor composition. Motor drive head has a few permanent magnets (not ring), turned in the corresponding position have the same number of permanent magnets, polarity attraction, when installed, motor drive the head and turn the permanent magnets in the magnetic coupling between each other, motor drive head, magnetic drive turned to run, the two are completely separated from the tank bottom, there is no mechanical transmission shaft through the tank. The design of the head, the connection between the head and the bearing, and the gap between the head and the bearing are directly related to the effect of CIP/SIP. Generally, the more open the head is, the better.

If the digital display thermostatic magnetic agitator fails, users should learn the necessary maintenance methods, including:

1. If the digital display constant temperature magnetic stirrer is heavily polluted, clean the buttons, contact points and wiring points before maintenance and check whether the external control keys work normally. Many faults are caused by dirt or dust of the equipment.

2. When the digital display constant temperature magnetic agitator is not powered on, it shall first determine whether the buttons, thermal relays, transformers and fuses of the electrical equipment are intact, and then judge the fault reason, and then conduct the test by power, listen to the sound, measure parameters and find out the fault reason, and then start the maintenance.

3. Before removing the digital display and constant temperature magnetic stirrer, it is necessary to carefully check whether there is any significant damage or crack in the equipment, understａnd its maintenance experience and service life, and then check the inside of the digital display and constant temperature magnetic stirrer.

4, after concluding that there is no problem with the mechanical parts, digital display thermostatic magnetic agitator electrical inspection, circuit fault inspection, to use the detection instrument to find the fault location, if not bad contact, then can be targeted to view the line and mechanical operation relationship, to prevent mistakes.
