Relevant knowledge of reactor refrigeration equipment
The reactor refrigeration equipment is a kind of water cooling equipment, which is a kind of cooling water equipment that can provide constant temperature, constant flow and constant pressure. The working principle of the reactor refrigeration equipment is to first inject a certain amount of water into the water tank in the machine, cool the water through the refrigeration system, and then send the low-temperature cooling water to the equipment that needs to be cooled by the water pump. The temperature rises and then returns to the water tank, and then the water is cooled by the refrigeration system.
Many people have questions about the frozen water flow detection of the reactor refrigeration equipment when they choose the reactor refrigeration equipment. Today, I will explain to you: Return water temperature and outlet water temperature detection:
After 30 minutes of starting up, check the system or chilled water system inlet and outlet thermometers through the unit's control system parameters, and the inlet and outlet temperature of the unit can be read when the unit is running. The difference must be around. If the temperature difference between the inlet and outlet water is too large, it means that the water flow of the water system through the plate is too small, which may cause the unit to fail to operate normally or be damaged.
Water pressure detection of inlet and outlet pipes:
Through the detection of the return water pressure and the outlet water pressure value, check the water flow rate of the chiller under the pressure difference between the inlet and outlet water pressures in the random manual of the unit. By referring to the water flow corresponding table or diagram of the unit in the manual, In order to judge whether the water system is normal, and use this difference to determine which section of the water pipeline has a large resistance value, and make corresponding rectification plans and actions.
Water pump running current detection:
By detecting the running current of the water pump of the reactor refrigeration equipment and comparing it with the rated current, it can be judged whether the actual water flow is larger or smaller than the rated water flow of the pump. Only by comprehensively judging with the previous parameters can an accurate water system detection be obtained. Analysis and judgment report.
What is the general reason for the high pressure of the reactor refrigeration equipment?
The cooling water flow is too low or the water temperature is too high (increase the cooling water flow or reduce the water temperature); too much refrigerant (discharge part of the refrigerant); the expansion valve opening is too small (adjust the expansion valve opening appropriately); the condenser copper tube/fin There is a lot of fouling on the chip, and the heat exchange effect is poor (clean or replace the filter);
Reaction kettle freezer temperature controller---simple, practical and accurate temperature control
The temperature controller of the refrigeration equipment of the reaction kettle, there is a choice of a large panel controller or a microcomputer temperature controller. The temperature controller also uses a chip, and the only thing left is the size of the panel.
To Sum Up
LNEYA reactor refrigeration equipment is widely used in the low temperature reaction field of chemical industry and other industries. It adopts 7-inch color touch screen display input and temperature curve recording. The entire system is a fully enclosed system. There is no water absorption during low temperature operation, which prevents ice crystals and improves the life of the thermal fluid.
