Lubricating oil is a liquid or semi-solid lubricant used for friction reduction, auxiliary cooling, rust prevention, cleaning and buffering. Good lubricating oil can help the cement brick machine to relieve the pressure caused by long-term operation, help the cement brick machine to coordinate the fuel consumption of the main engine, reduce friction, and extend the service life. What should be distinguished from the pros and cons of lubricating oil?
The viscosity and temperature resistance of lubricating oil are two dimensions to measure the quality of lubricating oil. The lubricating oil viscosity is too high, the fluidity is poor, the contact surface is slightly longer, the cleaning and cooling performance is poor, but the lubricating oil with good sealing performance is too small, the lubricant can not form a reliable oil film, the sealing performance is poor, the wear is large, and the lubrication cannot be maintained. Ground protection of the parts of the cement brick machine. Therefore, the viscosity of the lubricating oil should be considered reasonably when choosing lubricating oil for cement brick machine. In addition, due to the long running time of the cement brick machine, the temperature resistance of the lubricating oil is required to be high. The lubricating oil is required to have enough viscosity at around 300°C to ensure the realization of the lubrication effect; lubrication is still required at zero degrees or even minus 40 degrees Celsius The oil has sufficient fluidity to ensure the normal operation of the machine. The above is the requirement of lubricating oil viscosity and temperature resistance of cement brick machine.
The oxidation resistance of cement brick machine lubricating oil is better, the lubricating oil is easy to combine with oxygen at high temperatures, and its oxidation products make the lubricating oil deteriorate and fail, which will cause the engine to be prone to failure. Therefore, sufficient antioxidants should be added to the lubricating oil to prevent its oxidative deterioration.
