Diesel oil automatic supply circuit for bunker oil boiler

摘要

The invention provides a detailed description of the automatic supply circuit of diesel oil in a bunker oil boiler, from the gas furnace of the bunker boiler to the bunker oil, in order to make it easy to ignite, after the fuel oil is burned, before digestion, the diesel oil shall be automatically supplied and digested, so as to retrovert the gas furnace. This is an effective automatic diesel supply circuit.;The main line (a) supplied by 220V is connected with power LED (L-1), which is connected with timer and relay contact and force switch (2) through temperature regulator (1), and through force relay (pry 2),And then the power relay (pry2-1) for the bunker oil valve linked with it,Connect and connect power relay (pry2-2) for gelatin valve, automatically provide bunker oil valve (b.c.v) and LED (L-3), diesel valve (d.z.v) and LED (L-2), at the same time connect and connect power relay (pry1-2), automatically provide diesel.
