During the use of the crusher , if some protective measures are not taken in a timely manner, the crusher equipment may be easily corroded or prone to failure during use, thereby affecting the working efficiency of the crusher and failing to achieve the desired effect. The following points are the precautions for the crusher to be used in use:

1. Temperature affects the crusher

In the work, the temperature of each component has its own normal range. In the process of using the crusher, it is necessary to prevent overload operation at low temperature, ensure normal operation in the low-speed pre-warming stage, and then drive or work after the machine reaches the specified temperature. Do not ignore the important work because there is no problem at that time; Second, we must prevent the machine from running at high temperature. During the operation of the machine, the values ​​on various thermometers should be checked frequently. If the problem is found, the machine will be shut down immediately and the fault will be eliminated. For reasons that cannot be found for a while, it must not be treated without any treatment. In the usual work, pay attention to check the working condition of the cooling system. For water-cooled machinery, it must be checked before daily work to add cooling water. For air-cooled machinery, the dust on the air-cooled system should be cleaned regularly to ensure smooth air circulation.

2. Effect of impurities on the crusher

Generally it refers to mechanical impurities dust, soil, etc. Some non-metallic metal shavings, and the crusher wear debris material during use and the like generated in the jack. Once these impurities enter the inside of the machine and reach the mechanical mating surface, the hazard is great. It not only causes the relative movement to block, accelerates the wear of the parts, but also scratches the mating surface, destroys the lubricating film, and raises the temperature of the parts. High, lubricating oil deteriorates. It is determined that when the mechanical impurities in the lubricating oil increase to 0.15%, the wear degree of the first piston ring of the engine will be 2.5 times larger than the normal value; when the rolling bearing enters the impurity particles, the life will be reduced by 80% to 90%. Therefore, for crushers operating in harsh environments and complex conditions, first use high-quality, matching parts and lubricants, grease, and block the source of harmful impurities; second, do the mechanical protection work at the work site. To ensure that the corresponding mechanism can work properly and prevent various impurities from entering the inside of the machine. For faulty machinery, try to repair it at a regular repair site. When repairing on site, protective measures should also be taken to prevent parts replaced during on-site repair from being contaminated by impurities such as dust before entering the machine.

3. Effect of corrosion on the crusher

A phenomenon in which a metal surface is chemically or electrochemically reacted with a surrounding medium to cause damage is called corrosion. This corrosive effect not only affects the normal operation of the mechanical appearance equipment, but also corrodes the internal parts of the machine. Chemical substances such as rainwater and air enter the machine through external passages and gaps of mechanical parts, corrode the inside of mechanical parts, accelerate mechanical wear, and increase mechanical failure. This corrosion is sometimes invisible. If you can't touch it, it is easy to be ignored, so it is more harmful. In use, management and operators should take effective measures according to the local weather conditions and air pollution at that time, reduce effective measures, reduce the impact of chemical corrosion on machinery, and focus on preventing the intrusion of chemical components into the rainwater and air. .

H-Beam Steel

H-beam is a kind of economical section and high-efficiency section with more optimized cross-sectional area distribution and more reasonable strength-to-weight ratio. It is named after its section is the same as the English letter "H". Since all parts of H-beam are arranged at right angles, H-beam has the advantages of strong bending resistance, simple construction, cost saving and light weight in all directions, and has been widely used.
