Repair Blockages Blocks will cause a higher than normal pumping pressure. Depending on the application or system design, this blockage will usually result in a complete loss of lubricant flow into the total system and no bearing will be receiving lubrication. The loss of flow due to a blockage is first indicated with the higher than normal system pressure that is developed by the pump as it attempts to overcome this blockage. Higher pressure is limited, isolated and signaled through the use of various performance indicators, reset and relief, incorporated into the system design. Performance Indicators (Customer Supplied) NOTICE Never block a lube outlet that is designed to discharge lubricant. Performance indicators are pressure-sensitive devices that pinpoint excessive pressure in the lubricating system. These devices which are installed in the indicator ports of valves, signal a fault either by causing an indicator pin to protrude or by releasing lubricant into the atmosphere. Reset Indicator with Memory Reset indicators stop lube system operation when a fault occurs. These devices can be used in either master or secondary valves. When a lube line becomes blocked, the resultant high pressure pushes the indicator pin through the opening in the cap. The high pressure prevents the affected valve s piston from completing its cycle, causing a pressure backup through the valve which trips a pressure switch upstream from the valve and shuts off the pump. The indicator pin remains extended until it is reset manually. This helps locate the lube line that is blocked. Rupture Indicator Rupture indicators are used on valve applications where lube system pressure exceed 2500 psi. The high pressure from the lube line blockage causes a disc to rupture. The lubricant then forces an indicator to protrude, locating the blockage. The high pressure backs up through the system and trips a switch to shut the system off. When the fault is corrected, the disc must be replaced and the pin reset manually. Automatic Relief Indicator An automatic relief indicator pinpoints lube line blockage but allows the lube system to continue supplying lubricant to points that are not blocked. They are used primarily in secondary valves. The excessive pressure created by line blockage moves a piston, enabling the lubricant to escape through a vent. When the pressure is relieved, the spring resets the piston. Because these devices permit the lube system to keep operating when a lube point is blocked, a separate pressure switch connected to an audible alarm should be used to warn of high pressure (customer must supply these items). Locating Blockages NOTICE Use only clean oil filtered to the SAE -recommended cleanliness level of ISO 18/14 (ISO Standard 4406) when prefilling a system. The manufacturers of the machine tool and its component bearings should be consulted to ensure that the ISO 18/14 cleanliness level is adequate. 1. Make a visual inspection of the system. Check for crushed lines or improper valve installation. 2. Use the following procedure to verify that each valve outlet required to discharge lubricant can do so and that no pipe plugs have been installed in an outlet designed to serve a bearing or another valve. 16 313721A
Repair 3. Master Valves Without Performance Indicator a. Fill a hand pump (a) with clean, filtered lubricant. b. Connect hand pump (a) to the inlet of the master valve and slowly operate pump. c. If system will not cycle freely below 1500 psi, see Master Valves with Performance Indicator (below). Testing Master Valves for Blockages Master Valves With Performance Indicator (d) Connect hand pump (a) to the master valve as outlined in Step 3 and increase pressure to 2000 psi. a. Remove each port plug (6) one at a time and attempt to operate hand pump after each plug is removed. Do not exceed 2000 psi. b. If pressure drops and the master cycles freely after an indicator port plug is removed, then blockage is downstream in the area that is being served from that outlet. See Step 3. Connect hand pump (a) to the master valve as outlined in Step 3 and increase pressure to 2000 psi. Performance indicators (d) in the indicator ports will signal the location of the blockage. An indicator pin (d) in the up position indicates pressure is in that outgoing line and signals the blockage is in the area being served from this outlet (FIG. 12). If no indicator pins (d) are protruding, the blockage is in the master valve. NOTICE If all port plugs (6) are removed and the master will not cycle, the blockage is in this valve. When the port plug (6) of a blocked area is removed, a small shot of trapped lubricant will usually surge out of this outlet as the inlet pressure on the valve drops. If Master Valve Testing indicates a blockage in the master valve, the valve must be disassembled and cleaned. See Cleaning Valves, page 18. 6 a FIG. 12 d d ti13744 FIG. 13 a 6 ti13745 313721A 17
Repair Repairing Blockages Cleaning Valves If a blockage is indicated downstream of the master valve, install a hand pump (a) in the indicator port of the master valve that is common to the blocked area. (See FIG. 13). 1. Proceed to downstream secondary valve and remove all port plugs (6). 2. Slowly operate hand pump (a). If lubricant can be discharged freely through each of the indicator ports of the valve, the blockage is not in the supply line or the valve. Go to step 4. If lubricant is not freely discharged through open indicator ports of the second valve, the blockage is in this valve or its supply line. 3. Disconnect supply line at secondary inlet fitting and slowly operate hand pump to verify location. If blockage is in this valve, clean valve section. NOTICE Dirt and foreign material will damage lubricating equipment. Perform all service and disassembly under the cleanest possible conditions. Do not insert hard metal objects into piston bore (i.e., punches, screwdrivers, etc.). Use a brass rod and hand pressure only. 1. Relieve pressure, page 12. 2. Remove end plugs (12) only and try to move each piston (5) back and forth without removing the piston from the valve section. 3. If all pistons (5) move freely and there is no indication of a more serious problem, replace end plugs (12). If piston does not move freely: 2. Clean sections and pistons in suitable clean solvent until all lubricant has been removed. 3. Use compressed air to dry and blow out all ports thoroughly. A small metal probe should be used to make sure all passages are clean and open. Inspect cylinder bore and piston carefully for scratches, score marks or other damage. FIG. 14 a ti13746 NOTICE If either piston or cylinder bore is damaged, the valve must be replaced. All pistons are selectively fitted to the bore for proper clearance. 4. Install hand pump (a) into each indicator port of secondary valve in turn and slowly operate pump (FIG. 14). If high pressure exists, blockage has been located. Look for crushed line, tight bearing, improperly drilled fittings and/or lube inlet port. Correct as necessary. 4. If valve section and piston both appear in good condition, reassemble making certain piston slides smoothly but snugly in cylinder bore. 18 313721A
Repair Contamination Blockage If dirt, foreign material or any other form of contamination is found in a valve, cleaning that valve will only temporarily solve contamination blockage problems. The source of the contamination must be eliminated for satisfactory service. The system filtering method must be investigated, filter elements should be inspected and cleaned if necessary. The reservoir filling method should be reviewed to eliminate any chance of foreign material entering the reservoir during filling. Separation Blockage If a hard wax or soap-like material is found in the Valve Section, grease separation is occurring. This means that the oil is being squeezed from the grease at normal system operating pressure and the grease thickener is being deposited in the valve.
