The low temperature constant temperature circulation tank is a high-precision constant temperature source with its own refrigeration and heating. It can be used for constant temperature experiment in the water tank of the machine, or connected to other equipment through a hose, and used as a constant temperature source. It is widely used in research departments such as petroleum, chemical, electronic instrumentation, physics, chemistry, bioengineering, medical and health, life science, light industry food, physical property testing and chemical analysis, colleges and universities, enterprise quality inspection and production departments, working for users. Provide a cold-cooled, uniform temperature field source for constant temperature testing or testing of test samples or products, or as a source of heat or cold for direct heating or cooling and auxiliary heating or cooling.
In the daily use of low temperature constant temperature circulation tank, but we still need to constantly invest human and material resources to maintain the use of equipment, increase the service life of the equipment, so that it can effectively improve the work efficiency while producing high quality products. Simply give you a few tips:
1. The liquid medium should be added to the front tank of the low temperature constant temperature circulation tank. Generally, the liquid level is lower than the working surface by 30mm-50mm to prevent the heater from burning out;
2. The power supply is 220VAC/50Hz, and the equipment must have good grounding;
3, pump switch and refrigeration switch: equipment The province's circulating pump is automatically turned on when the equipment starts running, the refrigeration compressor will make the corresponding start or stop command according to the temperature of the equipment, unless there is a special need;
4, JMD series low temperature constant temperature circulating tank adopts the automatic control function of circulating pump, that is, when the equipment is running, the circulating pump runs automatically. When the equipment is running, because of the function of the circulating pump, the liquid surface will show a flowing pattern. There is no obvious flow state at the liquid tank interface during operation, which means that there may be a helium state and it should be exhausted in time;
5. The low temperature constant temperature circulating tank has its own cooling function. The cooling function can automatically issue the running or stopping command according to the temperature of the equipment. It can also artificially prohibit the compressor from running through the system parameters. When the equipment prohibits the compressor from running, the compressor needs to be set again. It will only resume normal cooling operation. In the cold season in winter, if the water temperature is lower than room temperature 5-10 degrees, you can try to turn off the compressor and realize some temperature control by single heating, which can effectively reduce noise and energy saving;
6. The instrument should be placed in a ventilated and dry place, and the back and sides should be separated from the obstacle by more than 300mm;
7. After the instrument is used, the power switch is turned off and the power plug is unplugged. If it is not used for a long time, the liquid in the tank should be drained and scrubbed clean;
8. When the temperature is above 60 °C, be careful to touch the surface of the thermostatic bath to avoid hot hands;
