Abstract

The invention relates to the technical field of ship processing, and discloses a flow guide pipe positioning and mounting method, which comprises the following steps of: positioning a propeller axis, mounting a propelling device, propelling a propeller at a slipway stage, and measuring data of a glass fiber reinforced plastic flow guide pipe according to the propeller axis, a propeller rotating plane line and a guide edge blade tip; drilling a small-end flange and a lower-end flange mounting base of the glass fiber reinforced plastic flow guide pipe, preparing a transition base and an adjusting gasket, and finally connecting and fixing by using bolts, so as to ensure the mounting precision of the whole glass fiber reinforced plastic flow guide pipe. According to the method, the flow guide pipe shipping work of the high-power propeller can be smoothly implemented, and the precision requirement can be met.

Description

technical field [0001] The invention relates to the technical field of ship processing, in particular to a method for positioning and installing a draft pipe. Background technique [0002] The high-speed law enforcement equipment transport ship is a special law enforcement official ship. In addition to high navigation safety and high survivability, it also requires excellent speed, maneuverability, seaworthiness under high sea conditions, close-range confrontation and maneuverability. Flexible maritime law enforcement capabilities. The ship uses four sets of high-power propulsion devices as the main power equipment. The glass fiber reinforced plastic guide tube that propels the propeller plays a very important role as the diversion part of the fluid driven by the propeller, and the installation quality must be guaranteed. However, the existing installation method is complicated and poor in precision, which is not conducive to the installation and subsequent use of the guide...
