What should be done if the cooling water of a pump freezes in cold weather? ? ? What are the main anti-freezing measures for pumps and pipelines in colder areas of the north? ? ?
Insulate the pipes; for pipes that are not in use, drain the liquid from them. If this cannot be done, provide heating – either electric heating or steam heating； Drain the liquid from the standby pump; if it doesn’t drain, you can start the standby pump – it will just consume a little more electricity.
Warm it up slowly using steam or hot water
If it has already frozen, use hot water to thaw it. In the northern regions, operating equipment must be installed indoors, while outdoor piping systems need to be insulated with heating elements; generally, electric heating strips are used, while steam heating is employed for special cases
Drain the liquid from within the spare pump’s casing; reduce the flow rate of the seal water – this way it’s less likely to freeze
