Regularly check the pressure, flow, temperature of each detection point of cement mill gydraulic system, prevent the cement mill gydraulic system from working under abnormal pressure and temperature for a long time, which can reduce the wear of cement mill gydraulic system, prevent internal leakage and ensure the normal operation of cement mill gydraulic system.

The leakage of cement mill gydraulic system is the result of comprehensive influence in many aspects. It is not only simple, traditional and negative to strengthen sealing, but also to eliminate the root cause of leakage systematically and take effective measures to deal with it.

To reduce the leakage of cement mill gydraulic system, reasonable measures should be taken to reduce the leakage of cement mill gydraulic system. Especially in the process of using, the management, operation and maintenance personnel engaged in vertical roller mill should strengthen the sense of responsibility, based on prevention and minimize the leakage of cement mill gydraulic system of vertical roller mill.

Hydraulic oil is not only the medium of power transmission, but also lubricant and coolant in hydraulic system. To ensure that the hydraulic system can work reliably and economically in all situations, the hydraulic oil must have the proper viscosity and good viscosity temperature characteristics. Viscosity is an important index of hydraulic oil.

For a certain hydraulic system, only working of vertical roller mill medium with limited viscosity range can be used to work normally. The viscosity is too large, the resistance increases, the temperature rises rapidly, the energy loss is large, and the system efficiency is reduced; The viscosity is too small, which increases the volume loss of the pump and reduces the oil film support capacity, which leads to dry friction between the moving pairs, and increases the leakage.

A high-quality vertical roller mill can not only save energy and protect environment, but also easily achieve the expected output of the equipment. Not only that, high-quality equipment manufacturers choose new high wear-resistant materials in production, and adopt the international leading production technology. The equipment produced can well meet the production needs of users, providing continuous, efficient and reliable service Safe production provides a more favorable guarantee.

The final output is related to all the equipment of the whole production line. For example, if your output requires 500t / h, you can't only require the hourly output of vertical roller mill to reach 500t, and the processing capacity of the front jaw, cone, belt conveyor, etc. should also match it, otherwise the final output will certainly not be reached. The configuration of a production line should consider all factors to meet your capacity requirements.

Firstly, the problem of insufficient system pressure is caused by the failure of the pressure regulating valve or the abrasion of the valve core of the pressure regulating valve. At this time, the oil filter needs to be removed to observe whether there are metal debris

If there are bright steel particles, it indicates that the working pump of vertical roller mill has wear problems.

If aluminum particles are found, it indicates the wear of vertical mill.

If there are black or copper particles, it means that the clutch wear failure.

In addition, the magnetic filter screen under the oil pan needs to be removed for inspection to see if there is any steel debris. Through the inspection of the above parts, it can be determined whether the oil temperature rise is caused by the component damage.

Old drivers who have operated excavators for many years may have encountered unusual noises in the ultrafine vertical mill. What is the cause of the noise in the ultrafine vertical mill? Today we will analyze the causes and solutions of noise in the ultrafine vertical mill from five aspects.

Pressure fluctuations and noise in the system are caused by improper mating of spool valve with valve bore or by dirt trapping in contact of cone valve with valve seat, blockage of damper bore, skewed spring or failure to move properly in valve bore.

Solution: Pay attention to cleaning and dredging the Yinni hole;Check the relief valve and repair or replace it if damage is found.
