High-pressure water jet flow system for removing rust of ships and working method thereof

Abstract

The invention discloses a high-pressure water jet flow system for removing rust of ships and a working method thereof. The system of the invention comprises a low-pressure water pipeline, a super-high pressure water pipeline, a cooling pipeline and a pneumatic pipeline, wherein the super-high pressure water pipeline comprises a lubricating oil cooler of a super-high pressure pump, a cooling pressure gauge, an super-high pressure motor and the super-high pressure pump; one end of the lubricating oil cooler of the super-high pressure pump is also connected with the super-high pressure pump through the cooling pressure gauge; the other end is connected the super-high pressure pump sequentially through a cooling temperature relay, a cooling filter, a lubricating oil cooling pump and a cooling pressure relay; and a rust removing nozzle is installed at the output end of the super-high pressure pump. The method comprises the steps of sucking stable water flow to be converted into super-high pressure water and jetting the super-high pressure water out through the rust removing nozzle. In the invention, because the high pressure water with the pressure up to 250 MPa, which is generated by the super-high pressure pump, is directly used to be passed through a spray nozzle and the high-speed water flow with extreme high level density is jetted out, the rust removing effect is good and delivering abrasive materials is not needed.

Description

technical field [0001] The invention relates to a ship derusting system, in particular to a ship derusting high-pressure water jet system and a working method thereof. Background technique [0002] Ship rust removal is the pretreatment of ship surface steel materials, the primary task before ship painting, the key step in ship repair and shipbuilding, and a relatively large system engineering. The traditional ship derusting method adopts manual derusting, shot blasting and water jet abrasive derusting. Manual rust removal relies on manual knocking and peeling of rust, which is very inefficient and of poor rust removal quality; shot blasting relies on steel shots thrown by a centrifugal pump to quickly impact the rust layer to achieve peeling of the rust layer, and the rust removal efficiency is relatively low. High, but the pollution is serious, and the treatment of steel shot is troublesome; water jet abrasive derusting is mixed with quartz sand in high-pressure water jet,...

Manual rust removal relies on manual knocking and peeling of rust, which is very inefficient and of poor rust removal quality; shot blasting relies on steel shots thrown by a centrifugal pump to quickly impact the rust layer to achieve peeling of the rust layer, and the rust removal efficiency is relatively low. High, but the pollution is serious, and the treatment of steel shot is troublesome; water jet abrasive derusting is mixed with quartz sand in high-pressure water jet, the abrasive has strong exploitation ability, and the experimental effect is good. However, the dock is very large, and the transportation of abrasive requires scaffolding, which is difficult to transport. easy
