Description

Double-line explosion-proof fuel distributing tank Technical Field The utility model relates to the technical field of centralized lubrication, in particular to a double-line explosion-proof oil separating tank. Background The intelligent double-line dry oil centralized lubrication system is efficient and accurate automatic lubrication equipment and is specially designed for multipoint lubrication requirements of large industrial machinery. According to the system, dry oil (lubricating grease) is quantitatively conveyed to each lubrication point through alternate pressure supply of the two main oil pipes, so that the manual maintenance cost is obviously reduced, and the equipment reliability is improved. The intelligent centralized lubricating system for the double-line grease is usually driven by the oil cylinder to drive the piston plate to reciprocate in the grease distribution tank, and in this way, the lubricating grease in the grease distribution tank can be effectively pressed into the double-line oil pipe. However, in practical applications, the two-wire tubing may experience problems with plugging. Once the two-line tubing is plugged, if the system is still constantly applying pressure to the split tank, this will likely lead to a sharp rise in the internal pressure of the split tank, causing serious consequences of tank bursting.
