Abstract
The utility model discloses a lubricating station oil path-based temperature automatic control device. The lubricating station oil path-based temperature automatic control device includes an electric contact thermometer, an electric heating tube and a relay, wherein the electric contact thermometer and the electric heating tube are installed in a lubricating station oil path; the electric contact thermometer and the coil of the relay are connected in series with each other so as to form a branch circuit; a first normally-open contact of the relay and the electric heating tube are connected in series with each other so as to form the other branch circuit; two ends of the two branch circuits are connected in parallel with two ends of a 220V alternating-current power source. According to the lubricating station oil path-based temperature automatic control device, the electric contact thermometer is utilized to monitor oil temperature in the lubricating station oil path in real time, when the temperature is lower or higher than the lower-limit or upper-limit temperature values of the thermometer, a lower-limit and upper-limit contact is switched off or switched on, so that the coil of the relay is switched on, and therefore, the contact of the relay is switched on, and thus, the work of the electric heating tube can be controlled, and automatic control of the oil temperature can be realized; and a long-term unsolved problem of the freezing of the lubricating station oil path can be successfully solved, and the normal operation of a hoisting machine can be ensured.
