The present invention provides a thermal flow detection and temperature measurement system for piston cooling oil of an internal combustion engine for ships, which includes a sensor unit and a digital temperature measuring instrument. The sensor part includes: a first protruding part forming a through hole inside and having a first temperature sensor and a heating wire in the through hole; a second protruding part adjacent to but spaced from the first protruding part, and A through hole is formed inside, and inside the through hole is equipped with: a second temperature sensor that subtracts the temperature of the piston cooling oil from the temperature provided by the first temperature sensor; a third temperature sensor that provides the above-mentioned temperature to the external central control center. Oil temperature; the fourth temperature sensor provides the measured oil temperature signal to the digital temperature measuring instrument arranged on the outer wall of the internal combustion engine. The digital temperature measuring instrument is arranged on the outer wall of the above-mentioned internal combustion engine, and includes a temperature display part and a flow identification part.
Description
technical field [0001] The present invention relates to a flow detection and temperature measurement system, and in particular to a piston of a marine internal combustion engine that senses the temperature and flow of piston cooling oil of a marine internal combustion engine at the work site so that the control unit can also sense the temperature and flow of the piston cooling oil. Thermal flow detection and temperature measurement system for cooling oil. Background technique [0002] The large-scale internal combustion engine for ships is the power mechanism that propels the ship forward, and the piston cooling oil of the internal combustion engine has an important impact on the safe operation and durability of the internal combustion engine. Therefore, depending on the detection method of the sensor that detects the above piston cooling oil, its reliability And durability is also different. [0003] figure 1 It is a schematic diagram of a thermodynamic flow detection and...
