MK Wind Turbine Hydraulic Rotary Joints Notes

1. MK Series uses a labyrinth sealing structure. During installation and operation, the drainage hole L must be connected by an oil pipe to the oil collection tank. And the oil pipe must not be blocked to avoid back pressure.
2. Inner leakage is allowed between each passage. Please pay attention to the compatibility of different working media to avoid cross-contamination.
3. The working fluid or hydraulic media should be filtered before being used. The filtration precision should be no lower than 10um.
4. A working temperature rise will reduce the viscosity of the working fluid to increase the leakage volume. So during operation, the cooling device should be accompanied.
5. The hydraulic system should be equipped with an automatic pressure regulator to compensate for the pressure loss caused by inner leakage.
