Processing Technology And Classification Of Dredging Hose
No matter what industry technology is the driving force for development, the value of technology lies not in leading but in application.
There are many types of large-diameter dredging hoses, but the technical processes are also different. The processing method of large-diameter wave-sparging rubber hose is different. The inner rubber hose of the composite tube is wound on the mirror steel wire or the steel wire rope on the coiling machine or the braiding machine.
The large-diameter rubber hose is synchronously coiled in the coiling machine or braiding machine between the middle rubber sheet between every two layers of steel wires or steel wire ropes.
Large diameter dredging hoses are divided into water delivery hoses, mud suction and discharge hoses, oil resistant hoses, acid and alkali resistant hoses, high temperature resistant hoses, steam hoses, and large diameter wear-resistant hoses according to the conveying medium.
Dredging Hose Processing technology
Large-diameter water hoses are used to convey or pump water and other neutral liquids at room temperature. It is mainly used for industrial suction and drainage, agricultural and forestry irrigation, urban drainage, etc.
Large-diameter dredging hoses can be divided into high-pressure large-diameter hoses and low-pressure large-diameter hoses according to the working pressure state. Among the processing technology, low-pressure large-diameter hoses are divided into low-pressure conveying large-diameter hoses (positive pressure) and low-pressure suction large-diameter hoses ( negative pressure).
The frame layer of high-pressure large-diameter rubber hose is multi-layer steel wire braiding or environmental reinforcement layer, and the frame layer of low-pressure large-diameter rubber hose is multi-layer fabric/shizi wire surround reinforcement layer, plus spiral steel wire frame reinforcement layer, and the negative pressure suction hose adopts double layers The spiral steel wire skeleton reinforced layer structure ensures that the pipe body will not be sucked or deformed under negative pressure working conditions.
- Use: It is a flanged dredging hose, which can be used on sand dredging ships such as seas, ports and rivers.
- Structure and performance: The dredging hose is composed of a synthetic rubber outer rubber layer with good wear resistance and weather resistance, a spiral steel wire skeleton layer, a middle rubber layer, and a thickened inner rubber layer of high wear-resistant rubber; the flanged dredging hose has certain flexibility High wear resistance and good wear resistance, thickened high wear-resistant rubber inner rubber layer effectively prolongs the service life of the hose.
