Abstract
The invention discloses the welding method of fire-fighting drawdown pump peculiar to vessel, it is characterised in that comprise the following steps, 1, weld must be cleaned out before weldering, the weldering meat at original cracking position is taken away, with handing over phase polishing machine mill to remove, clean ferrum oxide of must polishing after the plane of cracking position；2, fire pump welding position to preheat before welding, then uses interval weldering, dispersion weldering or postwelding hammering, taps weld seam and weld edge with hammer, taps with hammer after being soldered completely, until weld seam cools down；3, fire-fighting drawdown pump welds with water suction, water pipeline and must assure that through welding, is then welded with ribs, ribs thickness >=10mm outside pipeline；Often it is soldered one cracking position and checks cracks, weld again after then eliminating with carbon arc air gouging if any crackle.
Description
Technical field
The invention belongs to fire-fighting field of mechanical technique, particularly relate to the welding method of fire-fighting drawdown pump peculiar to vessel.
Background technology
Fire pump is mounted on boats and ships, fixed fire extinguishing system or other fire fighting devices, is used as conveying water or foam solution
Dedicated pump Deng liquid extinguisher.The type selecting of fire pump should be according to the technological process of fire pump application project, plumbing requirement, from
Liquid-conveying amount, Unit head, liquid property, pipeline are arranged and are operated five aspects such as operating condition and take in.Need
Professional and technical personnel is designed safeguarding reparation.
Summary of the invention
Technical problem solved by the invention is to provide the welding method of a kind of fire-fighting drawdown pump peculiar to vessel, has remediation efficiency
Height, low cost, effective feature.
In order to solve the technical problem of above-mentioned existence, the technical solution used in the present invention is as follows:
The welding method of fire-fighting drawdown pump peculiar to vessel, it is characterised in that comprise the following steps, 1, must be by dry for weld cleaning before weldering
Only, the weldering meat at original cracking position is taken away, with handing over phase polishing machine mill to remove, clean oxidation of must polishing after the plane of cracking position
Ferrum；2, fire pump welding position to preheat before welding, then uses interval weldering, dispersion weldering or postwelding hammering, strikes with hammer
Hit weld seam and weld edge, tap with hammer after being soldered completely, until weld seam cools down；3, fire-fighting drawdown pump and water suction, water is sent
Pipeline welding must assure that through welding, is then welded with ribs, ribs thickness >=10mm outside pipeline；Often it is soldered one cracking
Position checks cracks, welds after then eliminating with carbon arc air gouging if any crackle again.
Further, second step, stop timely water-cooled weld during weldering every time, interbed temperature controls below 50 DEG C.
Further, the impeller of fire-fighting drawdown pump, stator use corrosion resistant plate compacting to form through laser welding.
Compared with prior art, the invention has the beneficial effects as follows:
After the welded reparation of the fire-fighting pump housing, weld seam position is still good, and surface smoothness is high, and waterpower flow losses are little, and efficiency is high,
And easily clean inside, highly beneficial for conveying pure medium.The method remediation efficiency height, low cost, effective, have one
Fixed practical value.
Detailed description of the invention
Below the technical scheme of the preferred embodiment of the present invention is described in detail.
The welding method of fire-fighting drawdown pump peculiar to vessel, comprises the following steps, 1, weldering before weld must be cleaned out, former
The weldering meat at position of ftractureing is taken away, with handing over phase polishing machine mill to remove, and clean ferrum oxide of must polishing after the plane of cracking position；2, in weldering
Connect front fire pump welding position to preheat, then use interval weldering, dispersion weldering or postwelding hammering, tap weld seam and weldering with hammer
Tape edge edge, taps with hammer after being soldered completely, until weld seam cools down；Second step, stops timely water-cooled weld during weldering every time,
Layer temperature controls below 50 DEG C.3, fire-fighting drawdown pump welds with water suction, water pipeline and must assure that through welding, then outside pipeline
Side is welded with ribs, ribs thickness >=10mm；Often it is soldered one cracking position and checks cracks, then use carbon arc if any crackle
Gouge welds after eliminating again.
The impeller of above-mentioned fire-fighting drawdown pump, stator use corrosion resistant plate compacting to form through laser welding.
The foregoing is only explanation embodiments of the present invention, be not limited to the present invention, for the technology of this area
For personnel, all within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. made, should be included in
Within protection scope of the present invention.
