Problems solved by technology

[0003] Traditional fire water pipes are made of stainless steel. Since the telescopic water pipe has multiple stages, it will cause the telescopic water pipe to be heavy and inconvenient to use. If the aluminum alloy material is used for the processing of the fire water pipe, it can greatly reduce the cost of the telescopic water pipe. Self-weight, so there is an urgent need for a processing technology for fire-fighting water pipes to realize the processing of aluminum alloy fire-fighting water pipes

Abstract

The invention relates to the technical field of fire-fighting vehicles, in particular to a processing technology for a telescopic water pipe of a fire-fighting vehicle, comprising the following steps: blanking; correction of the roundness and straightness of the water pipe; grinding and polishing the inner and outer circular surfaces of the water pipes of each diameter ; Welding of water pipes, flanges and joint sleeves; sealing test of water pipe single components; hard anodizing of inner and outer surfaces of water pipe single components; surface lubrication treatment; overall assembly of telescopic water pipes; overall sealing test of telescopic water pipe components. In this process, the straightness and roundness of each water-saving pipe contained in the telescopic water pipe are first calibrated to improve the matching accuracy. Welding is performed before the hard anodizing of the water pipe monomer components, so as to ensure the normal welding of water pipes, flanges and joint sleeves. Hard anodizing is carried out on the inner and outer surfaces of each water-saving pipe monomer component, so that the inner and outer surfaces of each water-saving pipe have high hardness and wear resistance, and the impact of sand and gravel on the water pipe wall is reduced when the water source environment is harsh. s damage.

Description

technical field [0001] The invention relates to the technical field of fire-fighting vehicles, in particular to a processing technology for a telescopic water pipe of a fire-fighting vehicle. Background technique [0002] The telescopic water hose for fire trucks is specially used for fire trucks or other emergency vehicles to transport water to high fire sources, so as to quickly extinguish high fire sources. [0003] Traditional fire water pipes are made of stainless steel. Since the telescopic water pipe has multiple stages, it will cause the telescopic water pipe to be heavy and inconvenient to use. If the aluminum alloy material is used for the processing of the fire water pipe, it can greatly reduce the cost of the telescopic water pipe. Due to its own weight, there is an urgent need for a processing technology for fire-fighting water pipes to realize the processing of fire-fighting water pipes made of aluminum alloy. Contents of the invention [0004] The technical...
