The invention relates to an installation process of an impeller casing of a marine water jet propulsion device and provides installation process and tooling of an impeller casing of a marine water jet propulsion device. The tooling comprises a shaft tube and an outer circular plate installed on the periphery of the shaft tube, and a tooling locating spigot corresponding to the size of an impellercasing locating spigot is arranged on the outer circular plate. When the tooling is used for installing the impeller casing, the installation process comprises the following steps of: firstly, connecting the tooling and the impeller casing into a coaxial integral body, installing the integral body on a hull stern transom plate through an adjusting device, and respectively arranging the tooling and the impeller casiing inside and outside the hull stern transom plate; pouring epoxy to the stern transom plate and the impeller casing after adjusting the shaft tube and the water jet propulsion device to be coaxial by the adjusting device, and removing the tooling to realize the accurate locating and installation of the impeller casing on the hull stern transom plate. The invention greatly increases the locating and installation accuracy of the impeller casing of the marine water jet propulsion device, simplifies installation process and shortens installation time.
Description
technical field [0001] The invention relates to the installation process and tooling of the impeller cover of the water jet propulsion device of the ship. Background technique [0002] In the outfitting of ships, the positioning and installation accuracy of the impeller cover of the ship's water jet propulsion device is very high. Otherwise, it will directly cause low efficiency of the propulsion system and affect the performance of the ship. The installation process of the impeller cover of the existing ship water jet propulsion device requires two construction workers to stand inside and outside the impeller cover of the water jet propulsion device to coordinate and adjust the tooling; according to the inner surface of the impeller cover of the water jet propulsion device Measure positioning. This method has low measurement accuracy, large errors, and great dependence on the work experience of construction personnel, making it difficult to ensure the positioning and ins...
