When the line speed of the paper machine is low, one generation of paper products should be considered, and the width of the paper is not large. However, internal combustion engine oil, hydraulic oil or gear oil cannot be used to replace the circulating oil in the dry part of the paper machine. Due to the low temperature oxidation and corrosion resistance of internal combustion engine oil, the extreme pressure wear, demulsification and corrosion inhibition properties of hydraulic oil cannot meet the lubrication requirements of the dry part of the paper machine, so it cannot be replaced or mixed with paper machine special oil. The following editor will tell you how the circulating oil of papermaking machinery meets the higher performance requirements of the system.
The performance characteristics of the circulating oil of the paper machine: good viscosity-temperature performance, to ensure normal lubrication when the working temperature changes greatly; good oxidation stability, reduce the deterioration rate of the oil, and extend the service life of the oil; it has good rust prevention Performance, to ensure good anti-rust effect on lubricating parts; good foam resistance, make the bubbles generated during the cycle of oil easily disappear, to ensure normal oil supply and oil film formation; good anti-emulsification performance, make it mixed in the oil The water in the oil can be separated quickly to ensure the performance of the oil. It has good filtering performance and prevents clogging of the filter system; it has good extreme pressure and anti-wear performance to avoid wear of lubricating parts under heavy loads; it has good cleanliness and dispersion to prevent sludge sludge.
In the new high-speed wide-web paper machine, the main bearing of the wet end also adopts centralized automatic forced lubrication by the central lubrication station. In this system, the wet and dry parts of the paper machine are equipped with a central lubrication station, which is managed and operated by an automatic control system. In view of the high-speed and heavy-load continuous operation of modern paper machines, the properties of lubricating oils such as viscosity temperature, oxidation stability, extreme pressure, demulsification, and filtration are proposed.
