Embodiment Construction

[0046] One, construction condition of the present invention:

[0047] Before the construction, inspect the site and the progress of the hull construction to see if it meets the requirements for shafting and main engine installation and positioning, and take corresponding measures to eliminate the inconsistencies.

[0048] 1. Hull construction: the main welding work and rectification work of the hull structure after the front bulkhead of the engine room and below the upper deck should be completed.

[0049] 2. The tightness test of the main hull area, including cabins and cabinets connected to the hull inside the engine room, is to be completed.

[0050] 3. The baseline deflection of the hull should be within the specified range. The baseline of the hull and the centerline of the two main hulls should be drawn and marked, and unnecessary temporary supports in the above areas should be removed.

[0051] 4. In addition to the above requirements, the construction of other hull st...

Abstract

The invention discloses a ship spray pump installation process, aiming at providing a ship spray pump installation process with high installation accuracy and good reliability, which can meet the requirements of ship inspection specifications and engine shaft system installation process. The invention comprises the following steps: a. positioning the centerline of the shaft system; B. positioningthe spray pump shaft; c. installing injection pump shafting. The invention is applied to the technical field of marine jet pump installation technology.

Description

technical field [0001] The invention relates to a jet pump installation process, in particular to a ship jet pump installation process. Background technique [0002] The jet pump is also called the water jet propeller, which refers to a propeller in which the jet part of the propulsion mechanism is immersed in water, and the reaction force generated by the jet water is used to drive the ship forward. It is composed of water pumps, pipes, suction ports and spouts, etc., and can change the jetting direction of the water flow through the spouts to realize the manipulation of the ship. The efficiency is lower than that of propellers, but the maneuverability is good, especially for shallow water channels with sediment bottoms. Water jet propulsion Has good adaptability. At present, the installation accuracy and reliability of marine jet pumps are low, and it is difficult to meet the technical requirements of ship inspection regulations and turbine shafting installation. Conten...
