Low temperature cooling circulation pump is a device that uses mechanical refrigeration to achieve closed loop low-temperature liquid circulation. It mainly maintains the temperature stability of experimental or industrial equipment through mechanical refrigeration and is widely used in scientific research and industrial fields. Its core function is to provide stable low-temperature cooling support for rotary evaporators, double-layer glass reactors, freeze-drying equipment, etc., ensuring accurate and controllable temperature during experiments or production processes.
The working process of low-temperature cooling circulation pump can be divided into three key steps:
Heat exchange cooling: The pump body is driven by an electric motor or pneumatic transmission to extract high-temperature coolant from the cooled equipment and deliver it to the condenser inside the water tank. The condenser is made of high thermal conductivity materials such as copper, and the cooling liquid exchanges heat with the internal environment when flowing through the condenser, resulting in a rapid decrease in temperature.
Circulating transportation: The cooled liquid enters the cooled equipment again through the outlet pipeline, forming a closed-loop circulation. The pump body adopts an anti cavitation impeller design to ensure stable liquid transportation in low temperature environments and avoid performance degradation caused by bubble generation.
Intelligent temperature control: The device is equipped with a microcomputer control system and P.I.D. temperature regulation technology, which can monitor the temperature of the coolant in real time and automatically adjust the working status of the pump (such as flow rate and cooling power), ensuring that the temperature fluctuation range is controlled within ± 0.1 ℃, meeting the requirements of high-precision experiments.
Main functions
Temperature control: Provide low-temperature cooling for equipment such as rotary evaporators, double-layer glass reactors, spectrophotometers, etc., to maintain the temperature of experimental or industrial equipment within the set range.
Pressure regulation: By stabilizing the pressure of the circulating working fluid, it ensures the normal operation of the low-temperature system and avoids system abnormalities caused by gasification or liquefaction of the working fluid.
Energy saving and consumption reduction: By recycling working fluids to remove excess heat, energy consumption can be reduced and system energy efficiency can be improved.
