Mobile crushing stations are generally operated in open environments, and the working conditions are often harsh. In the winter, temperatures drop, especially in regions like Xinjiang, Inner Mongolia, and the northern parts of Northeast China, where freezing conditions may occur. Without proper maintenance, it can seriously affect the normal production and lifespan of mobile crushing stations. To ensure the normal operation of the crusher and achieve the goals of stable and efficient production, equipment inspection and maintenance must be carried out, addressing insulation and antifreeze issues. So, how should mobile crushing stations be maintained during the cold winter?
1. Cleaning of Mobile Crusher:
Cleaning the exterior of the diesel engine, chassis, and working devices of the mobile crushing station can remove dirt and stains. During the cleaning process, damaged devices and oil leakage points can be identified, preparing for subsequent maintenance. It is strictly forbidden to use high-pressure, high-temperature water jets to wash parts with high waterproof requirements, especially the electrical components, to avoid damage.
2. Fluid Replacement:
- Use high-quality antifreeze in winter, selecting a type that is about 10°C lower than the lowest temperature of the region. The antifreeze should have long-term effectiveness in winter freeze protection, summer boil protection, corrosion resistance, and scale prevention. Clean the water tank if sediment is detected.
- Choose low-viscosity winter engine oil for the diesel engine, preferably high-performance oil to significantly extend the lifespan of the diesel engine. Replace or clean the oil filter when changing the oil.
- Timely replace lubricating oil, using winter-grade gear oil for the gearbox, transfer case, differential, and steering gear. Clean the components during oil replacement.
3. Component Maintenance:
- Check the battery wiring and adjust the electrolyte density for electrical equipment maintenance. Maintain the starter motor and adjust the generator charging voltage. Regularly charge the battery in winter and maintain the preheating device.
- For brake system maintenance, ensure an adequate brake fluid level and monitor if the crushing quality deteriorates. Check the oil-water separator and ensure the drain switch is functioning correctly. Inspect the brakes for signs of weakening, pulling to one side, insufficient pedal force, and non-retraction, adjusting promptly.
4. Time Adjustment:
Considering the impact of low temperatures on equipment, adjust the production plan to avoid prolonged operation of equipment in extremely low temperatures.
