1. Drain water: In winter, the water in the water pump and its pipelines is prone to freezing, causing equipment damage. Therefore, it is necessary to ensure that the water pump and its system are drained of water when not in operation. You can empty the water in the pump by opening the drain valve, or use hot water to melt the ice.
2. Insulation measures: In cold environments, insulation layers or materials can be installed on the water pump unit to prevent the water pump from freezing. In addition, maintaining room temperature above 5 ℃ can effectively prevent equipment from freezing due to low water temperature.
3. Preheating measures: Preheating before starting the water pump in cold environments can effectively prevent difficulty or damage caused by low temperatures. Preheating should be carried out according to the manufacturer's recommendations, while ensuring that all lubricants and liquids are at the appropriate temperature to ensure optimal performance.
4. Check and replace lubricating oil: Check the lubrication system of the water pump unit in a timely manner and replace the lubricating oil as needed. Under low temperature conditions, the original lubricating oil may thicken, affecting the lubrication effect. It is necessary to ensure the use of lubricating oil suitable for low-temperature environments to maintain the smooth operation of the water pump.
5. Check the sealing and valves: Regularly check the sealing condition of the water pump to ensure that the sealing components will not leak due to shrinkage or expansion under temperature differences. At the same time, check whether the valves are working properly, especially the vent valve and drain valve, to ensure that they can respond quickly when needed.
6. Avoid cold start: The water pump should not be started directly after being stopped for a long time, especially when the temperature is low. A comprehensive inspection and appropriate preheating of the unit should be carried out first to prevent damage to the components due to cold start.
7. Remove accumulated water: Ensure that there is no residual water in the water pump and its piping system. Water accumulation not only increases the risk of icing, but may also cause rusting and corrosion of metal components.
By using the above maintenance methods, the service life of the diesel engine water pump can be effectively extended, ensuring its safe and efficient operation in cold weather.
