20 Liter short path distillation of CBD|ZZKD INSTRUMENT
20L Double Short Path Distillation
Low-temperature circulating pump is a necessary cooling device for refining cbd oil in 20-liter short-path distillation. Pay attention to the correct use method and maintenance method when using it to avoid damage to the instrument.
low temperature coolant circulation pump
How to use and maintain the low temperature circulation pump
1. When the low temperature coolant circulation pump is used, the degree is not displayed. In this case, it may be the circuit board connection line, whether it is bad contact, whether the sensor is falling off, etc., you can plug in the connection line, dry the circuit board and start up. .
2. When there is a phenomenon of non-refrigeration, it may be due to system problems, such as system leakage, and the cause of dirty system blockage. Only professional personnel can be found for maintenance, and the cooling rate is slow and the same.
3. When the equipment is used again, there is no external circulation. First, check if the circulation pump is blocked. If it is blocked, just remove the blockage, or the power box will fall off, or the valve will not open. problem appear.
4. When the whole machine has no power failure, check whether the fuse is blown. If it is only necessary to replace the fuse, there is another possibility that the phase sequence of the power supply is wrong. Just adjust the position of the two fire lines. used.
5. The air-cooled fully enclosed compressor unit is cooled, and the microcomputer intelligent control refrigeration system is automatically turned on. The refrigeration system has multiple protection devices such as delay, overheat and over current.
6. The low temperature coolant circulation pump can output the cold liquid in the tank, cool or thermostat the experimental container outside the machine or establish a second constant temperature field.
7. The microcomputer has a timed shutdown function. After this function is enabled, the timer shutdown time can be set arbitrarily within 0~100 hours.
8. Double window, red and green LED display temperature setting value and temperature measurement value, digital resolution 0.1 °C, the microcomputer can correct the temperature measurement deviation, so that the digital display accuracy reaches 0.1 °C.
9. The low temperature coolant circulation pump has a microcomputer software lock function, which can lock the parameter setting values of the system, and the unrelated personnel cannot change the set parameters.
