Wind Turbine Bolt Installation: How Many Hours of Operation Require Oil Change for Hydraulic Wrench Pumps?

When installing wind turbine bolts, many users have inquired about the required oil change interval for hydraulic wrench pumps after a certain number of operating hours.

Hydraulic wrench pump oil has specified usage guidelines. Generally, oil should be replaced after 300 continuous operating hours. If used in field conditions and any of the following issues arise, oil replacement is necessary:

1. Contamination from dust entering the oil.

2. Unusual odor development.

3. Water ingress causing oil emulsification.

4. Oil degradation or discoloration.

These conditions impair the pump's functionality.

For manufacturing facilities with cleaner environments and lower usage, oil should be changed at least every six months. Wind turbine installation firms with high usage and harsh conditions should change oil monthly.
