Simple fault handling method for constant temperature oil bath

Simple fault handling method for constant temperature oil bath

Because of its high temperature and constant temperature characteristics, thermostatic oil baths are widely used in biological, physical, chemical, environmental, scientific and other fields. However, equipment may cause such problems or minor problems due to improper operation or working environment. Now let me talk to you about how to deal with these problems.

For example, during the use, you may encounter the power indicator light, but the temperature control display does not light. At this time, we check whether the temperature controller output is normal. Generally, such a fault is mostly caused by a transformer on the temperature controller or In the process of use, there is a phenomenon of virtual soldering, find the cause of the fault, and deal with it.

If it is found that there is no power supply when the power switch is turned on, check whether the power socket has power, whether the fuse is intact, and whether the power switch has fault. This fault is mostly caused by the power switch being damaged.

If it is found that the constant temperature oil bath is far beyond the set temperature for a long time during operation, we can observe whether the heating indicator is extinguished after reaching the set temperature. If it is off, the temperature controller is normal, just replace the relay. If the heating indicator is always on, the temperature controller is broken and needs to be replaced.

Also, if it is found that the temperature cannot be increased after using for a period of time, the resistance of the heating tube becomes large or the connection line of the heating pipe is corroded, resulting in a large contact resistance. The former needs to replace the heating tube, and the latter cuts the wire at the joint, and at the same time The rusted part of the heating pipe joint is cleaned, and the new connection and the method can be judged by visual inspection.

If you encounter the above simple faults when using the constant temperature oil bath , you must be patient to check the reasons, eliminate them one by one, and use the correct method to carry out maintenance and repairs in a reasonable way to improve our work efficiency.
