Q：How harmful is water in hydraulic oil?

  First, the way water into the hydraulic system:

• Mechanical failure, such as poor sealing, cooling coil leakage so that water into the oil.

• In the hot and humid climate, the oil tank breathing and brought in.

• Working environment humidity, rain, snow, ice melt water pollution.

  Second, the harm of water on the hydraulic system:

• Can react with the hydraulic oil, the formation of acids, gums and sludge, water can also precipitate additives in the oil; the main effect of water is to reduce lubrication, dissolved in hydraulic oil in trace amounts of water can accelerate the wear of high-stress components, only by the water (100-400) × 10-6 mineral oil rolling bearing fatigue life studies have shown that the bearing life is reduced by 30% -70%. Water can cause sticking of the control valve, in the pump inlet or other low-pressure parts to produce vapor damage, corrosion, rust and corrosion of metal.

  Third, the solution:

• Strengthen the monitoring of the water content in the oil, outdoor use of hydraulic equipment, it is best to use weatherproof tents, strengthen the system sealing measures, waterproof entry. Tank breathing holes installed dryer, the conditions of the system can be installed "super-absorption type" filter drier.
