Knowledge of common faults in small chemical high and low temperature cycle devices

The status of small chemical high and low temperature circulation devices in the industry is increasing day by day, not only the technical level, but also the quality is constantly improving.
The accurate control of its temperature is very important, because the temperature is too high, it will lead to the processing process.
The desired temperature quality control effect will also cause unnecessary losses
.


1.
The equipment thermometer fails, causing the small chemical high and low temperature circulation device to overheat
.

It is important to know that the placement of each part of a device is very important.
The temperature probe should be placed at the air outlet, which refers to the hot air outlet or inlet, which can make the temperature of the constant temperature phase more stable, and can easily control the flushing temperature.
The placement of the probe It should also be fixed.
If there is looseness, there may be a temperature control deviation, and the temperature in the device fluctuates greatly
.

In this way, when the fault that the device temperature is too high is found again, you can check whether the probe is placed in place
.

2.
The motor of the small chemical high and low temperature circulation device is reversed.
If the motor in the equipment is reversed, it will directly affect the normal circulation, resulting in a decrease in air volume and abnormal temperature, which may be due to excessive temperature or unstable or unheated temperature.
etc.

_
Therefore, when the equipment temperature is too high, you can check whether the motor is reversing
.

　　3.
In daily use, timely cleaning and maintenance of the small chemical high and low temperature circulation device can reduce the failure of the instrument
.

　　4.
Before using the equipment, clean up the internal impurities before operation
.

　　5.
It is better to clean the power distribution room at least once a year.
The cleaning here refers to sucking up the dust in the room
.

6.
The outside of the box should be cleaned more than once a year, and can be wiped with some clean water when cleaning
.
