When maintaining the cone crusher, there should be seasonality. For example, when the temperature is low in winter, diesel and water are more likely to freeze, and it is difficult to start the machine. When the crusher is used in winter, because of the cold climate, the diesel engine is difficult to start, and the cooling water And the electrolyte is easy to freeze, and at the same time, the wear of parts and the fuel consumption increase significantly, so corresponding maintenance measures must be taken before the winter, and the crusher must be thoroughly inspected and maintained to ensure that the construction machinery can survive the winter safely. Therefore, maintenance in winter is different from other seasons. How to maintain the crusher in winter?

1) Cleaning of hydraulic cone crusher
Cleaning the exterior of the diesel engine, chassis, and working devices of construction machinery can play a role in descaling and decontamination. During the cleaning process, damage to various devices, components and oil leakage can also be found, and preliminary work can be done for the next maintenance. It is strictly forbidden to use a high-pressure and high-temperature water gun to wash the parts with high waterproof requirements, especially the electrical parts, so as to avoid damage.

2) Selection and replacement of oil
Selection of fuel oil
Diesel is easy to wax at low temperature, viscosity increases, fluidity deteriorates, and atomization is poor, which deteriorates the combustion process and reduces the power and economy of diesel engines. In order to make the diesel engine work softly and reduce fuel consumption, diesel with lower freezing point should be selected. The general selection principle is: the freezing point of diesel oil is about 5°C lower than the ambient mixing degree. The diesel grades available in winter are: -10#, -20#, -35#, etc.
During maintenance, the fuel system should be cleaned. Thoroughly clean all filters, replace the fuel filter element, discharge the sewage from the oil-water separator and clean it, and check the working condition of the oil pump to eliminate hidden troubles.
Replacement of diesel engine oil
Diesel engines should use low-temperature oil with lower viscosity. Try to choose high-performance engine oil, which is not only not easy to oxidize at high temperature, but also will not leave deposits in the precision parts of the diesel engine, which can greatly extend the life of the diesel engine. Multi-grade oil can work in a wide temperature range, generally, multi-grade oil with viscosity grade of SAE5W-40 or SAE10W-40 can be selected. When changing the oil, the oil filter should be replaced or cleaned.
Change oil and grease
During seasonal maintenance, replace the gear oil in the transmission, transfer case, differential and steering gear with gear oil for winter use, and pay attention to cleaning when changing the oil.
3) Maintenance of parts
Maintenance of the diesel engine cooling system Check the working state of the thermostat to prevent the water temperature of the diesel engine from being too low or too high. Remove limescale from the water jacket. It is necessary to choose a long-term antifreeze that is about 10°C lower than the lowest temperature in the area where the construction machinery is used, and has antifreeze in winter and anti-boiling, anti-corrosion and anti-scaling in summer. Once the water tank is found to have silt deposits, remove it immediately.
Maintenance of electrical equipment Check the motor wiring of the battery. Check and adjust the electrolyte density. Service the starter motor. Increase the alternator charging voltage. The battery should be charged frequently in winter. Maintain the preheater.
The maintenance of the brake system should pay attention to whether the brake fluid is sufficient and whether the quality is deteriorated. Check the oil-water separator. Whether the drain switch is working properly. Check whether the brakes are weak, deviate, the pedaling force of the brake pedal is insufficient, and the brake does not return, and adjust in time.
