How Temperature and Impurities and Corrosion Affect Crushers
1. Temperature impact on the crusher
In the work, the temperature of each component has its own normal range. Crusher in the process of use, one to prevent overload operation at low temperatures, to ensure the normal operation of the low-speed pre-temperature stage, so that machinery to reach the prescribed temperature before driving or work, do not ignore its important to do because there is no problem at the time; two to prevent the machinery in the high temperature operation, machinery running process to frequently check the value of various temperature table, find problems immediately stop to check, find fault even troubleshooting. For a moment to find the reason, must not be processed without still make the machinery work with disease. In the usual work, pay attention to check the working condition of the cooling system. Water-cooled machinery, the daily work must be checked before adding cooling water; air-cooled machinery, but also to regularly clean up the dust on the air-cooled system to ensure that the cooling air duct smooth.
2. The impact of impurities on the crusher
Mechanical impurities generally refers to dust, soil and other non-metallic substances and crusher in the use of the process since the rise of some metal chips, wear products, etc.. Once these impurities enter the inside of the machinery, reach the mechanical with the surface between, its harm is great, not only make the relative movement out of block, accelerate the wear of the parts, and will bruise with the surface, destroy the lubricant film, make the parts temperature rise, lubricant deterioration.
According to the determination, the mechanical impurities in the lubricating oil increase to 0.15%, the engine first piston ring wear degree will be 2.5 times larger than the normal value; rolling bearing into the impurity particles, its life will be reduced by 80% to 90%. Therefore, for the crusher working in a harsh environment, complex conditions, one should use high-quality, supporting parts and lubricants, grease, blocking the source of harmful impurities; two to do a good job of mechanical protection of the work site to ensure that the corresponding institutions can work properly to prevent a variety of impurities into the mechanical interior. Faulty machinery, as far as possible to the regular repair places for repair. Site repair, but also to do a good job of protective measures to prevent the replacement of parts in the field repair before entering the machinery contaminated by dust and other impurities.
3. The impact of corrosion on the crusher
Metal surface and the surrounding media to chemical or electrochemical reaction and damage to the phenomenon known as corrosion. This corrosion effect will not only affect the normal work of the mechanical exterior equipment, and will corrode to the internal parts of the machinery. Such as rain in, air chemicals and other mechanical parts through the external channels, gaps and so on into the mechanical interior, corrosion of mechanical parts inside, accelerate mechanical wear and tear, increase mechanical failure. As this corrosion effect is sometimes invisible. Untouchable, easy to be ignored, and therefore its harm is greater. In use, management and operators should be based on the local weather conditions at the time, air pollution, to take effective measures to reduce effective measures to reduce the impact of chemical corrosion on machinery, focusing on preventing rain and air chemical composition of the mechanical intrusion.
