Problems solved by technology

[0005]The normal supply of abrasives and the stable state of the high-pressure water line determine the use effect of abrasive jets. In the existing technology, the supply of abrasives is through the specific Venturi adsorption of the jet pipeline. To achieve the mixing of abrasive and water, the supply speed of abrasive can

Abstract

The invention provides an abrasive jet control system which comprises an abrasive feeding device and a control module; the abrasive feeding device comprises a water jet nozzle (2), a conveying mechanism (3), a water knife sand tank (4) and a water pump assembly (6), and the water knife sand tank (4) is used for storing jet abrasives and conveying the abrasives to the water jet nozzle (2) through the conveying mechanism (3); the water pump assembly (6) is used for pumping water to the water jet nozzle (2) so that the water can cooperate with the abrasives to achieve cutting; and the control module comprises a control center, an interaction unit and a detection unit. According to the abrasive jet control system, after cutting is completed, abrasives remaining in a conveying pipeline are blown out through an air compressor, so that sand accumulation in the pipeline is prevented, and the situation that due to the fact that the abrasives are stuck in the pipeline, sand and water cannot be mixed normally, and the maintenance frequency of the system is increased is avoided.

Description

technical field [0001] The invention relates to the technical field of abrasive water jets, in particular to an abrasive jet control system. Background technique [0002] Abrasive water jets are formed by introducing abrasive particles into high pressure water. The introduction of abrasive particles greatly improves the effect of the water jet, so that the abrasive water jet can achieve rust removal, sand cleaning and cutting operations under relatively low pressure. Abrasive jet equipment needs to use a high-pressure generator to achieve high cutting efficiency. However, when pure water cutting cuts relatively hard materials, its speed is still not ideal. This is also the basis for the initial development of abrasive water jet technology. If there is no waterjet sand for water cutting, the accuracy and depth of cutting will be greatly reduced. Laboratory data shows that if you don't put abrasives, you can only cut a 3mm titanium plate, and the cut is jagged. With the add...
