The invention discloses a temperature and pressing measuring device on a water-cooling wall surface of a
combustion chamber and a
machining method thereof. The device comprises a pressure-measuring
pipe, a temperature-measuring
pipe, a temperature-measuring joint
nozzle, and a pressure-measuring joint
nozzle, the temperature-measuring joint
nozzle and the temperature-measuring
pipe are integrally welded, the pressure-measuring joint nozzle and the pressure-measuring pipe are integrally welded, the temperature-measuring pipe and the pressure-measuring pipe are welded with a
combustion chamber inner wall, a
combustion chamber interlayer, and a block together, and the block and a cavity arranged on a
combustion chamber jacket are welded together. The
machining method includes: finishing of the external surface of the
combustion chamber inner wall is performed; temperature-measuring holes and pressure-measuring holes are machined on the
combustion chamber inner wall, the combustion chamber interlayer, and the block; the temperature-measuring pipe and the pressure-measuring pipe are welded with the combustion chamber inner wall and the combustion chamber interlayer together; the temperature-measuring pipe and the pressure-measuring pipe penetrate through the temperature-measuring hole and the pressure-measuring hole on the block and are welded with the block together, and the block is welded with the cavity on the combustion chamber jacket together. According to the device and the
machining method thereof, the
cooling effect of a measuring point area and the structural intensity of the combustion chamber are not affected, and the leakage of cooling media to the inner side of the combustion chamber and the outside of the combustion chamber interlayer is avoided.
