A multifunctional spray gun system for ship repair

Abstract

The invention belongs to the field of ship repairing equipment, and in particular relates to a multifunctional spray gun system for ship repairing. Including a multi-functional spray gun, the multi-functional spray gun is provided with an air inlet and a water inlet; the multi-functional spray gun includes a water gun tube main body, a nozzle, a jet regulating tube, and an air jet regulating tube; the end of the jet regulating tube near the outlet end is a closed structure, and the outlet end There is a long strip-shaped air outlet that runs through the inside and outside along the circumference of the tube. The inner diameter of the jet regulating tube is equal to the outer diameter of the jet regulating tube, and the outer diameter of the jet regulating tube is smaller than the inner diameter of the nozzle; The position is adjustable. According to the requirements of green ship repairing processes such as paint and rust removal, sea organism removal and purging, the present invention can realize ultra-high pressure water jet, cavitation jet and air injection by changing the position of the jet flow adjustment pipeline and air injection adjustment pipeline inside the spray gun. Function, achieve the purpose of one gun with multiple functions, improve the versatility of the equipment in the field of ship repairing technology, and reduce the cost of ship repairing.

Description

technical field [0001] The invention belongs to the field of ship repairing equipment, and in particular relates to a multifunctional spray gun system for ship repairing. Background technique [0002] With the rapid development of society and economy, the total amount of world trade exchanges is growing rapidly, and maritime transportation is also playing an increasingly important role, and the demand for ships as the main means of transportation at sea is also gradually increasing. Since the hull is immersed in seawater every day, it is corrosive to the hull steel plate, and marine organisms will also attach to the surface of the hull. As the service life of the ship increases, rust will occur on the hull steel plate and a large number of marine organisms will adhere to it. Affect the service life and performance of the ship. Therefore, the surface of the ship must be cleaned regularly. [0003] The ship repair process involves the paint and rust removal of the ship's out...

AI Technical Summary

Problems solved by technology

[0004] When the existing ultra-high pressure water jet technology and cavitation jet technology are applied in the field of ship repair, corresponding proprietary equipment is required. When the process is applied, it involves the transportation, arrangement and installation of multiple equipment, which will inevitably lead to Increased construction costs

In the process of derusting with high-pressure water, the surface after derusting is prone to anti-rust phenomenon because it is not dried by jet blowing

In addition, the existing cavitation jet technology mainly relies on the structural characteristics of the nozzle to realize the cavitation jet. The occurrence rate of cavitation in the jet process is low and difficult to control, and the efficiency of practical application needs to be improved.
