Nowadays, there are more and more machines, and it is normal to start at long temperatures. However, the reaction of the machine is a bit slow or abnormal at colder temperatures. The temperature on our side is OK, but there is more trouble in the northeast, especially the old machine that takes a long time. However, today we will introduce the starting skills of mechanical equipment such as sand making machine in low temperature environments.
The appearance of the diesel engine, the chassis and the working device of the cleaning engineering machine can play the role of descaling and decontamination. In the cleaning process, the damage of each device, components and oil leakage parts can be found, and the preliminary work for the next maintenance and repair can be done. It is forbidden to use high-pressure and high-temperature water guns to flush parts with high waterproof requirements, especially electrical parts, to avoid damage.
Diesel is prone to wax formation at low temperatures, viscosity increases, fluidity deteriorates, and atomization is poor, which deteriorates the combustion process and reduces the power and economy of the diesel engine. In order to soften the diesel engine and reduce fuel consumption, diesel with a lower freezing point should be used. The general selection principle is: the condensation point of diesel is about 5 °C lower than the environmental mixing. The diesel grades available for winter are: -10#, -20#, -35#, etc.
The fuel system should be cleaned during maintenance. Thoroughly clean all the filter screens, replace the fuel filter, discharge the sewage from the oil-water separator and clean it. Colleagues check the operation of the oil pump to eliminate hidden troubles.
Diesel engines should use low temperature oil with low viscosity. Try to use high-performance engine oil. This kind of oil is not easy to oxidize at high temperature, and it will not leave any deposits in the precision parts of the diesel engine, which can greatly extend the life of the diesel engine. Multi-grade oils can be operated over a wide temperature range. Generally, multi-grade oils with a viscosity rating of SAE5W-40 or SAE10W-40 are available. Replace or clean the oil filter while changing the oil.
When changing seasons, replace the gear oil in the transmission, transfer case, differential, and steering gear with gear oil for winter. Pay attention to cleaning when changing oil.
