-120 degree heat sink test how to use the cryogenic unit

-120 degree heat sink test cryogenic unit can meet different refrigeration temperature requirements, widely used in chemical, pharmaceutical, biochemical and other industries in the field of low temperature reaction, fast refrigeration speed, safe and reliable
.
If it is operated for a long time, it will consume a lot of costs
.
And in order for the user to run well, then how should the user choose qualified equipment
.
1.
-120 degree heat sink test before the cryogenic unit is turned on and used 1.
Placement environment: When handling and moving, it is necessary to keep the body vertically upward
.
Provide a stable fixed device to ensure that the cryogenic unit of -120 degree heat sink test will not tilt.

ENSURE THAT THE DISTANCE BETWEEN THE SURROUNDING WALLS AND THE BACK PANEL OF THE INSTRUMENT IS MORE THAN 70CM TO ENSURE THAT THERE IS SUFFICIENT VENTILATION TO ALLOW THE EQUIPMENT TO DISSIPATE HEAT
IN TIME UNDER HIGH OPERATION.
2.
Attention to supporting connection: check the tightness
of the connecting pipe interface between the -120 degree heat sink test cryogenic unit and the peripheral equipment.
Closed applications of external equipment, such as reactors, need to ensure that the pipeline materials and properties match
the heat transfer fluid and temperature range.
It is necessary to ensure that no air bubbles remain in the system, ensure that the outlet of the heat conduction medium is connected to the lower interface of the reactor, and the inlet of the heat transfer medium is connected to the upper interface of the reactor Do not place items
such as work, quantity, clamps and products.
3.
Filling refrigerant: without special reasons, the general equipment will not produce a large number of leaks
.
If a certain amount of refrigerant leaks due to improper use or after repair, the refrigerant
needs to be refilled.
Charging refrigerant should pay attention to the refrigerant type
used in the unit.
4.
Filling heat conduction fluid: heat conduction medium heat conduction medium can not use water, the filling steps are detailed in the draining and adding liquid operation instructions, when power-on test operation, check the working conditions of each part, whether there are abnormal phenomena and sounds Second, -120 degrees heat sink test cryogenic unit is in use 1.
Make preparations before start-up, pay attention to the heat conduction medium used in the equipment and open the exhaust, set the temperature and turn on the operation key to start temperature control
.
2.
When starting, pay attention to whether the temperature, pressure, liquid level, hydraulic, air pressure, electrical system, air pressure system, instrument signal and other protection of the equipment are normal
.
If there is any abnormality, it should be stopped for inspection immediately until the cause is found out and eliminated
.
Third, -120 degrees heat sink test after the low temperature unit is stopped 1.
Power off through the program: click the "Stop" button of the main control window, and the standby unit components can be directly powered off after the standby unit parts completely stop working
.
2.
When the work is stopped, all joysticks, etc.
should be placed in the non-working position, and the electrical control switches, knobs, etc.
should be restored to the off state and cut off the power supply
.
3.
Clean it after each use, no dirt, the processed parts are stored neatly, and there is no leakage at the interface of each transmission pipe
.
4.
If you need to not work for a long time, when the ambient temperature of the equipment is lower than 0 degrees, the water inside the system is easy to cause cracking of the condenser components, so when stopping, it is necessary to drain all the internal water to prevent the pipeline from rusting or cracking, resulting in damage
to the condenser.
And discharge
the internal heat conductive medium of the device.
-120 degree heat sink test cryogenic unit during use, should be maintained frequently, as far as possible to extend the service life
of the equipment.
