Why Set Delayed Start For Heater Chiller's Compressor?
High and low temperature experimental equipment is a device that can provide high-temperature and low-temperature circulating liquids for other experimental equipment. It has the advantages of fast heating and cooling, precise temperature control, and simple operation. It is an ideal equipment for pilot tests in modern laboratories. The entire liquid circulation system of the high and low temperature experimental equipment is closed, and the circulation system has an expansion vessel. The expansion vessel does not participate in the circulation of the liquid, but is only a mechanical connection, so no matter how the temperature of the circulating liquid is, the expansion medium can always maintain normal temperature .
Since the entire circulation system is airtight, there will be no oil mist at high temperature, and there will be no phenomenon of absorbing moisture in the air at low temperature, which prolongs the service life of the heat transfer oil. High and low temperature experimental equipment is widely used in industries such as petroleum, chemical industry, physics, chemistry, bioengineering, pharmaceutical research, electronic instrumentation, light industry and food, and is an ideal high-precision constant temperature source.
Many new users and friends just got the high and low temperature experimental equipment, maybe they can’t wait to turn on the equipment and try it without even reading the manual, but after turning on the refrigeration function button of the heating cooling circulator to start working, they found that the compressor did not start. Ask our staff if the compressor is faulty. Of course, this is definitely not caused by a compressor failure, but a protection function we have set for the compressor: delayed start. The compressor is one of the components of the refrigeration system of the high and low temperature test equipment, and it is also the key to the entire refrigeration system, so the high and low temperature test equipment produced by laboao Instruments also fully protects it.
We all know that refrigerators and air conditioners cannot be placed upside down, and the same is true for high and low temperature experimental equipment. This is to prevent lubricating oil from flowing into the compressor to form liquid shock and damage the internal parts of the compressor. Delayed start can avoid This phenomenon. In addition, because the internal pressure of the compressor is still relatively high just after the compressor stops, if we start it immediately at this time, the motor will start under high pressure, and it may fail to start because the starting current is too large. The delayed start can stabilize the high and low pressure inside the compressor, and the equipment can start normally.
