Introduction to pipeline
(1) Two-line main pipe and branch pipe: From the lubrication pump to the oil inlet of all distributors, the pressure is relatively high. Cold-drawn seamless steel pipes are usually used, and the material is 10 or 15-gauge steel. Severely corroded pipes must not be used; (2) Oil supply pipe: From the distributor to the oil inlets of all lubrication points (the oil holes of the bearing seat), the pressure is relatively low. Usually drawn copper pipe is used, which is convenient for piping when it is bent. There are also cold drawn of seamed steel pipes or stainless steel pipes; (3) Use hose joints when connecting to moving parts. piping layout requirements (1) The pipeline should try to avoid high temperature radiation and cooling water spray and other places where the temperature is too high or too low, especially the hose joints; (2) The pipe layout should not affect the operation of the host and other equipment, and should be safe and reliable, so as to facilitate the work, observation and maintenance; (3) The piping should be horizontal and vertical, neat and beautiful. Minimize bends or small-angle bends, and use large arcs to reduce oil flow resistance; (4) When the installation conflicts, the small pipe should be replaced by the large pipe and the low-pressure pipe should be replaced by the high-pressure pipe; (5) Pipes should not be in contact when they cross each other, and should be separated by a certain distance; (6) The joints of parallel pipes should be staggered to avoid affecting the installation and disassembly; (7) In order to facilitate the disassembly and cleaning of the pipeline, the union should be properly installed, but it should be used sparingly to reduce the possibility of leakage.
