Description
Technical Field
The invention relates to the technical field of underwater cutting, in particular to a water jet cutter assembly.
Background
More and more oil gas is transported through under water now, need use the oil gas pipeline at the in-process of transporting oil gas, this has just avoided carrying out the cutting operation to the oil gas pipeline under water.
The existing underwater cutting in the market mainly adopts the traditional electric arc-oxygen cutting technology, and the working principle of the technology is that high temperature generated by the underwater electric arc and chemical reaction heat generated by oxygen and a metal element to be cut are utilized to heat and melt the metal to be cut, and molten metal and oxidized slag in a cutting seam are blown off by means of the impulsive force of oxygen flow, so that the cutting seam is formed. The required cutting length is obtained along with the continuous movement of the underwater electric arc and the continuous supply of oxygen, so that the aim of cutting off the cut metal material is fulfilled. When cutting operation is carried out, a diver holds the cutting torch by one hand and holds the cutting strip by the other hand, the cutting strip is arranged in a jaw of the cutting torch, the cutting strip is screwed and fixed, and then the cutting strip is arranged on a cutting point. When cutting, in order to prevent the inner hole of the cutting strip from being blocked, the oxygen is started and the arc is started to cut while the power supply is informed. When the cutting strip is replaced or the cutting is stopped, the power-off is informed firstly, and then the oxygen is turned off. When the cutting operators are alternated, the power supply must be cut off, and the cutting torch should be properly placed near the cutting seam and cannot be randomly placed.
When using conventional arc-oxygen cutting techniques, safe operation in the process is important, and divers should note the following: the underwater cutting operation needs to be fully prepared, a cutting circuit and a cutting gas circuit are connected, and obstacles and various explosive articles which may endanger the operation safety in an operation area are removed; and (II) performing cutting operation underwater, and forbidding using oil pipes, steel cables, ship bodies, anchor chains or seawater as grounding wires under any conditions, wherein the grounding wires must use flexible cables with enough conductive sectional areas to be directly connected with the structure to be cut and must be firmly connected. And (III) cutting operation is carried out underwater, an operation platform or a working frame is required to be arranged, and as the diver has great danger in the suspension state operation and is careless, diving accidents can be caused, so that the diver is not allowed to carry out engineering cutting in the suspension state. And (IV) the diver should be vigilant for the underwater crush injury at any time. When cutting, enough avoidance positions are reserved before the component is cut, and the final cutting work is carried out after the component is located at the safest and most reliable position, so that the component is prevented from being crushed and damaging equipment worn. And (V) when the cutting operation is carried out underwater, the cutting torch is prohibited from touching any part of the body of the cutting torch or other operators, particularly, the metal helmet is not required to be touched, and accidents are prevented.
The traditional electric arc-oxygen cutting technology has great potential safety hazard, a diver usually has higher requirements on underwater working environment during underwater operation (particularly deep water operation), and oxygen explosion danger is easy to occur during pipeline cutting operation, so that the safety of the diver during underwater operation is not high.
