Slick Stuff ! Many of our industrial lubricants are enhanced with CERFLON® ceramic lubricating technology CERFLON acts like microscopic ceramic ball bearings to add more lubricity. Our formulas are more effective than most other industrial lubricants containing PTFE or ® TEFLON . CERFLON® is a registered trademark of, and a brand owned by Ceramic Reinforced Technologies. TEFLON® is a registered Trademark of DUPONT. ® Power Transmission Reliability Look for worn hoses Call 877-GO4-GUNK for local distributors www.gunk.com Shaft alignment in a Flash. Let us show you how! ® Check the hoses in the system for the proper length and signs of wear. It’s rare for a hose to burst because the rated working pressure was exceeded. Normally, hoses rupture because of a poor crimp or from rubbing on a beam, another hose or Bled dry some other object. If rubbing can’t be avoided, invest in a reel of hose sleeves, which are available from a variety of manufacturers. A hose should not exceed about 4 ft. in length, unless it moves with a machine member. Also, inspect system piping to verify that a hose is included where you connect to a valve bank or cylinder. The hose absorbs Figure 5. There should be no continuous flow from the bleed the hydraulic shock genvalve on a piston accumulator. erated when oil is rapidly deadheaded. An exception to this rule is that you should use only hard piping when connecting to a vertical or suspended load. Pilotoperated check valves and counterbalance valves are used to hold the load in the raised position. Verify that pipes that are mounted to structural elements are made using proper hydraulic clamps. Ordinary beam and conduit clamps aren’t acceptable, because they can’t absorb the shock generated in the piping or tubing. Space the clamps about 5 ft. apart along the run and within 6 in. of the pipe or tubing terminations. Once the system is thoroughly inspected and upgraded, develop a preventive maintenance schedule to make these checks on a regular basis. Many times, no thought is given to the hydraulic system as long as it’s running and the machine is operating. Final 2008 Industrial Ad #2 for Plant Services Mag.
