Answer: (1) Low water volume or low water pressure; the inlet valve should be opened wider or the water pressure increased. (2) Scaling on the heat exchange tubes of the cooler; clean off the scale. (3) If the cooling water temperature is high, contact the water supply party to lower the water temperature.
(1) If the water volume is low or the water pressure is low, increase the inlet valve opening or raise the water pressure. (2) Scaling on the heat exchange tubes of the cooler; clean off the scale. (3) If the cooling water temperature is high, contact the water supply party to lower the water temperature.
Circulating water quality, water volume, water pressure, supply water temperature； Circulating gas thermometer gas volume ； Wax formation, etc.

1. The design parameters of the water cooler itself, such as the heat exchange area, the material of the heat exchange tubes, and the medium undergoing heat exchange. 2. Water temperature and flow rate. 3. Whether the water quality is clean and whether there is any scaling. 4. Changes in medium temperature, pressure, and flow rate.
Inlet temperature, water flow rate. Equipment issue
Pressure, temperature, flow rate, structure of the heat exchanger itself
1. The heat exchanger design is not appropriate. 2. Medium flow rate, pressure, and temperature. 3. Pipe diameter of the pipelines. 4. Scaling and wax formation on the heat exchanger
1\ If the water volume is low or the water pressure is low, increase the inlet valve opening or raise the water pressure. 2\ The heat exchange tubes of the cooler are scaled; clean the scale. 3\ If the cooling water temperature is high, contact the water supply party to lower the water temperature.
1. If the water volume is low or the water pressure is low, increase the inlet valve opening or raise the water pressure. 2. The heat exchange tubes of the cooler are scaled; clean the scale. 3. If the cooling water temperature is high, contact the water supply provider to lower the water temperature.
(1) If the water volume is low or the water pressure is low, increase the inlet valve opening or raise the water pressure. (2) Scaling on the heat exchange tubes of the cooler; clean off the scale. (3) If the cooling water temperature is high, contact the water supply party to lower the water temperature. When synthetic methanol is produced, paraffin is formed and adheres to the walls of the water cooler tubes, reducing the cooling efficiency. The amount of cooling water can be appropriately reduced, and syngas at a higher temperature can be used to melt paraffin wax.
