A hybrid integrated ultra-high pressure premixed abrasive jet equipment

Abstract

The invention discloses series-parallel integrated high-pressure pre-mixing, grinding and jetting equipment. The series-parallel integrated high-pressure pre-mixing, grinding and jetting equipment comprises an ultrahigh-pressure moving pump station and a three-dimensional machine tool platform, and also comprises a tandem mixing valve body and a parallel grinding tank; an input port is formed at the left end of the tandem mixing valve body; a vertical flow dividing pipe is arranged at the upper end of the input port; an low-position input hose is arranged at the lower end of the vertical flowdividing pipe; a high-position input joint is arranged at the upper end of the vertical flow dividing pipe; a transition valve body is arranged at the lower end of the parallel grinding tank; a pure water input pipeline and a mixed liquid output pipeline are arranged on the two sides of the tandem mixing valve body correspondingly; a bias blind channel and a main horizontal channel are formed in the tandem mixing valve body; and a manual cut-off valve rod is arranged on the middle part of the main horizontal channel. The series-parallel integrated high-pressure pre-mixing, grinding and jettingequipment can solve the problem that the pre-mixing, grinding and jetting work has low continuity, can effectively avoid the condition that the equipment cannot work continuously caused by the pump stopping and sand loading process and can improve the operation efficiency of the equipment.

Description

technical field [0001] The invention relates to the technical field of abrasive water jet mechanical equipment design, in particular to a hybrid integrated ultra-high pressure pre-mixed abrasive jet equipment. Background technique [0002] The water jet is a high-speed water stream of different shapes formed by the nozzle, and the flow rate of the jet depends on the pressure drop before and after the nozzle outlet section. Water jetting is the simplest form of energy transformation and application. Usually, the power-driven pump completes a suction and discharge process of water, pumps a certain amount of water to the high-pressure pipeline, and makes it reach the nozzle with a certain amount of energy. The hole diameter of the nozzle is required to be much smaller than that of the high-pressure pipeline, so this certain amount of water reaching the nozzle must be accelerated if it wants to flow out of the nozzle hole. In this way, the water that accelerates condensation t...

Problems solved by technology

[0003] However, the existing pre-mixed abrasive jet equipment cannot realize the problems of poor continuity of the pre-mixed abrasive jet, and cannot effectively avoid the situation that the equipment cannot continue to operate due to the shutdown of the pump and sand loading process, which seriously restricts the operating efficiency of the equipment; Abrasive jet equipment cannot divide high-pressure water into two channels for input. It can neither realize the mixing of sand and water at the upper end of the abrasive tank and form a fluidized function, nor can it realize the input function of multiple water flows in the transition valve body at the bottom of the parallel abrasive tank. Some pre-mixed abrasives The jet equipment cannot directly input high-pressure water into the middle of the parallel abrasive tank, and cannot provide water source for the sand-water fluidization in the central area of ​​the parallel abrasive tank. Some pre-mixed abrasive jet equipment cannot realize the sand-water circulation and mixing fluidization function in the central area of ​​the parallel abrasive tank. It has not solved the technical problem of sand-water mixed fluidization in a single position in the parallel abrasive tank, and it is also impossible to avoid the change in the concentration of the abrasive mixed liquid in the later stage of equipment operation. Some pre-mixed abrasive jet equipment cannot realize multiple serial mixing valve bodies working in series , it is impossible to realize the high-pressure water splitting input of the series mixing valve body and the mixed liquid output and continuous working function, and the front mixing abrasive jet equipment cannot realize the mixing ratio of water and sand in the fixed parallel abrasive tank, and cannot limit the mixed liquid The output concentration cannot meet the needs of the actual situation
