Winter antifreeze measures for the hydraulic system of automatic casting sand molding machines

With the arrival of winter, the low temperature environment has brought many challenges to the hydraulic system of the automatic casting sand molding machine. In order to ensure the normal operation of the equipment in cold weather and prevent the production interruption caused by freezing damage to the hydraulic system, enterprises need to take a series of effective antifreeze measures. The following are some recommended winter antifreeze measures to help you maintain the stability and reliability of the hydraulic system.

Maintenance points for the hydraulic system of the automatic casting sand molding machine:

1. Choose the right hydraulic oil

In a low temperature environment, the viscosity of the hydraulic oil will increase, resulting in unsmooth operation of the system. It is recommended to choose a hydraulic oil dedicated to low temperature, which still maintains good fluidity at low temperatures to ensure the normal operation of the hydraulic system.

2. Check the hydraulic oil temperature regularly

In winter, monitor the temperature of the hydraulic oil regularly to ensure that it remains within the normal range. You can consider using a heating device to heat the hydraulic oil when the temperature is too low to avoid excessive viscosity.

3. Use antifreeze

Adding an appropriate amount of antifreeze to the hydraulic oil can effectively lower the freezing point of the hydraulic oil, thereby reducing the risk of freezing caused by low temperatures.

4. Strengthen insulation measures

Insulating the pipes and oil tanks of the hydraulic system can effectively reduce heat loss. You can use insulation materials to wrap the pipes, or set up insulation covers around the oil tanks to ensure that the hydraulic oil is kept at a suitable temperature.

5. Regular maintenance of the hydraulic system

Before the arrival of winter, conduct a comprehensive inspection of the hydraulic system, including pipes, joints, and cylinders, to ensure that there are no leaks or damaged parts. Regularly replace the hydraulic oil and clean the filter to keep the system in optimal condition.

6. Adjust production plans

In cold weather, adjust production plans appropriately to avoid high-load operations in extremely low temperature environments. You can choose to operate the hydraulic system during periods of relatively high temperatures to reduce the possibility of freezing damage.

7. Employee training and awareness raising

Train operators on the use and maintenance of hydraulic systems in winter to improve their awareness and operating skills of anti-freeze measures and ensure that they can detect and deal with potential problems in a timely manner.

Winter anti-freeze measures are essential for the hydraulic system of automatic casting sand mold molding machines. The risks of hydraulic systems in cold weather can be effectively reduced by choosing the right hydraulic oil, regularly checking the oil temperature, using antifreeze, strengthening insulation, regular maintenance, adjusting production plans, and conducting employee training. Hopefully, these measures will help you keep your hydraulic system running properly in winter and ensure smooth and efficient production.
