Machine Survey It is recommended that in the process of developing the lube system, a survey of the machine is made, and a schedule of lubrication points is created. This schedule should include the location of the bearing or lube point, the bearing size, 8-Hour lube requirement, and the measuring devices to use at each point. It may also be desirable to add an area for any remarks for each lube point and note any special considerations, which must be made for that particular point.
• • When lubricant lines are routed in an area where they could be damaged, adequate guarding must be installed. Common materials such as angle iron, channel iron, and heavy wall pipe can all be used to fabricate guards. Be sure to allow adequate slack in lines to facilitate for movement of parts of the machine.
Use only one feed line and injector per bearing as shown on the right. Do not combine two feed lines together for two lube points, as shown on the left. In other words, it is ok to feed one bearing with 2 or more injectors. It is not acceptable practice to feed two or more bearings with one injector. If two bearings are supplied by one feed line, as shown in the example on the right, one or the other bearing will received more lubricant than the other bearing.
Outputs from adjacent outlets may be combined by installing a special closure plug (303-174993) in one or more outlets. Lubricant from a plugged outlet is redirected to the next adjacent outlet in descending numerical order. Outlets 1 and 2 must not be plugged since they have no cross-port passage to the next adjacent outlet. Long Plain and Flat Bearings, Large Diameter Bearings Special consideration should be given to bearings that are extremely long or large in diameter.
cutting. See the supply line charts for each system type for recommended tube size and wall thickness to use. Copper tubing should never be used in lubrication systems, as it is not rated for the pressure which can be developed in an automatic lubrication system. Do not confuse Lincoln’s copper-coated steel tubing (62175; 62176) with copper tubing. The copper coating on the steel tubing is to provide corrosion resistance to the steel tubing.
Guidelines for High Pressure Grease Systems: 1. 2. 3. 4. 5. 6. Using a manual grease gun, confirm each lubrication point, which will be connected to the lubrication system, will ac cept lubricant. Use the same size pipe or tubing on all parts of the main supply line, including riser, ceiling run, branch lines, and drop lines. Where the main supply line has various branch lines; the branch lines can be reduced in size by the use of the Pipe or Tube Equivalency Charts in the Appendix.
Individual points can be adjusted at the injector. By adjusting the output at the injector the lubricant output can be adjusted to suite one individual point. If all or the majority of all the system needs more or less lubricant, the cycle rate can be increased or decreased as required. In some situations it may be necessary to add injectors to increase the output to one or two specific lube points. See Section 2 of this manual for combining injector outputs.
the importance of replacing any components with new components that have pressure ratings that meet or exceed the system pressure requirements. Trouble Shooting – Centro-Matic Systems Symptom Possible Cause Corrective Action Turn on power to controller, timer or motor. Most timers and controllers have power lamp that No electrical power to controller, should light when power is present. Check timer, or motor (electric pumps) fuses/circuit breakers on circuit(s) for all CentroMatic system components.
Pressure switch incorrectly set or Set pressure switch to correct system pressure not functioning or replace if defective. Move pressure switch closer to injector that is Pressure switch too close to pump the greatest distance from pump. Pump turns off before all injectors Use Lincoln pressure switch or insure that cycle Pressure switch reacting to surges proper snubber is installed in other pressure in supply line (Oil systems) switches Increase system pressure as required.
Trouble Shooting – Quicklub Progressive Systems Fault: Blockage in the downstream progressive system Cause: • • Correction: Bearing, lines, or metering valves clogged. In the case of SSV 6 through SSV 12 metering valves, outlet ports 1 and/or 2 are closed. The fault can be identified by : a) Grease leaking from the pressure relief valve; b) The fact that the indicator pin on the primary valve does not move in and out when the pump runs.
Trouble Shooting - Modular Lube Systems DESCRIPTION In a Lincoln Modular Lube lubrication system, lubricant from the pump flows through the metering devices and to the lubrication points serviced by the system. If any component of this system does not freely accept and discharge its portion of the lubricant, a blockage has occurred. This blockage will result in higher than normal pressure to be developed by the lubricant pump.
Pin Type Indicators High pressure from lube line blockage causes a pressure sensitive disc to rupture. The lubricant then forces an indicator pin to protrude, indicating the location of the blockage. The high pressure backs up through the system. When the fault is corrected, the disc must be replaced and the pin reset manually. Atmospheric Indicators These indicators give visual indication of excessive system pressure.
Master Divider Valve Without Performance Indicators: With pressure on the master divider valve as outlined in step 2, remove the alternate outlet plugs one at a time and attempt to operate the manual pump after each plug is removed. Do not exceed 2,000 PSI. If pressure drops and the master cycles freely after an alternate outlet plug is removed, then blockage is downstream in the area that is being served from that lubricant outlet. See Step 3.
disassembly. With the individual sections on the bench, remove the end plug from both ends of the section. Taking one section at a time remove the piston, if it appears to be jammed, try removing it from the other direction. With badly jammed pistons it may be necessary to use a brass rod and lightly tap piston out. Clean sections and pistons in a suitable clean solvent until all lubricant has been removed. Use compressed air to dry and blow out all ports thoroughly.
Centro-Matic System Schematic Centro-Matic System Notes • • • • • • • Centro-Matic systems operate with lubricant pressure provided by the pump. The system must “vent” or reduce the pressure in the lubricant supply line to a pressure low enough that the injectors will reload with lubricant for the next lubrication cycle. This is the purpose of the vent valve. If one injector in the system fails, all other injectors will continue to deliver lubricant normally.
Modular Lube System Schematic Modular Lube System Notes • • • • • • • • • • • • Modular lube divider valves must have a minimum of three working sections. Modular lube progressive systems operate on lubricant flow, not pressure. The lubricant pump delivers lubricant to the master, or primary valve. The master divider valve proportions the lubricant volume delivered to the secondary divider valves.
Quicklub System Schematic Quicklub Progressive Lubrication System Notes • • • • • • • • During an ON cycle, the pump supplies lubricant to the Primary (Master) Divider Valve. The Primary Valve meters the amount of lubricant supplied to the Secondary Valves. The Secondary valves meter the amount of lubricant delivered to the lubrication points. The output volume of SSV valves is changed by installing a special closure plug in one of the outlet ports.
