Precautions for the actual use of fully enclosed high and low temperature circulation devices

In many occasions, it is necessary to use a closed cycle industrial heating machine, especially in the laboratory, the common process requirement is to control the temperature of the reactor and make the material in it react
.
1, the fully enclosed high and low temperature circulation device in the work of the low temperature fluid medium through the pipeline under the action of pressure into its input port, along the electric heating vessel internal specific heat exchange runner, the use of fluid thermodynamic principle design path, take away the high temperature thermal energy generated in the work of the electric heating element, so that the temperature of the heated medium rises, the electric heater outlet to obtain the process requirements of the high temperature medium
.
2, the fully enclosed high and low temperature circulation device uses electrical energy to convert heat energy to heat the material to be heated, refrigeration using a compressor can quickly raise or lower so that it reaches the set temperature, control the refrigeration and heating temperature
of various reactors.
3.
The liquid addition and emptying of the fully enclosed high and low temperature circulation device are carried out at the
same time.
There is a device inlet above the equipment, the exhaust valve is on the side of the equipment, and a special auxiliary tool can be used to insert a word hole, close clockwise, and open
counterclockwise.
If a reversal occurs, it may lead to damage
to the circulating pump.
4, the fully enclosed high and low temperature circulation device when the liquid emptying, but also need to pay attention to protective measures, to ensure that the thermal conductive medium meets the system requirements, to ensure that there is no precipitation, color and corrosiveness, if there is a small amount of precipitate should be stable precipitation, when adding thermal conductive medium, can not add the precipitate to the system
.
5, the fully closed high and low temperature circulation device filling should pay attention to prevent spillage, and always observe the liquid level display window on the side of the equipment to prevent overflow into the electrical cabinet caused by equipment damage and pollution, before adding liquid, you should check whether the relevant pipelines are fully open, whether the equipment drainage port is closed
。 6, the fully enclosed high and low temperature circulation device should pay attention to when emptying the liquid, open the sealing cover counterclockwise when adding liquid, insert the funnel to inject the thermal conductive medium, add liquid to the expansion level, open the exhaust valve counterclockwise when emptying, click the emptying button on the main control page of the device touch screen, cycle for many times to guide the liquid emptying after the liquid level is not until it falls, at this time it means that the internal air has been basically emptied, we are running the drain and adding liquid for about half an hour, closing the exhaust valve can use the equipment
normally 。 Fully enclosed high and low temperature circulation device is often used in the chemical, pharmaceutical industry and laboratory small tests, etc.
, divided into stainless steel reactor and glass-lined reactor, FRP reactor, etc.
, for the different materials used in the process is also different, users can choose the appropriate temperature control device
according to the actual situation.
