What impact does deteriorating lubricant quality have on the machine unit?

The temperature of the bearing shells rises. 3. The lubrication and sealing properties of the oil deteriorate, which can cause vibration in the unit. 4. This leads to the melting of the tungsten alloy in the bearing shells.
1) The efficiency of the oil pump decreases, resulting in a lower oil pressure. 2) Water and mechanical impurities are present in the oil, which increases its viscosity and undermines its lubricating properties. 3) The lubricating and sealing capabilities of the oil decline, leading to vibration in the machinery. 4) The oil oxidizes and becomes acidic, causing corrosion in all components that come into contact with it; at the same time, a large amount of rust is formed, which raises the temperature of the shaft bearings
If it is EH oil, more serious consequences can lead to sticking of the solenoid valve and runaway of the turbine.
