Description
Technical field
The utility model relates to a kind of front mixing abrasive water jet abrasive mixed assembly system, is specially adapted to Abrasive Water Jet Machining system.
Background technology
Since British Fairhurst in 1986 proposes front mixing abrasive water jet system, water jet researcher updates front mixing abrasive water jet hybrid system.At present, most typical front mixing abrasive water jet abrasive mixed assembly system is to rely on the deadweight of abrasive material and the pressure differential on equilibrium water road, abrasive material is entered be positioned at the hybrid chamber of high-pressure abrasive material tank bottom to mix with high pressure water.But because this hybrid mode is subject in tank the impact of amount of abrasive larger, along with the minimizing gradually of amount of abrasive in abrasive can, feed concentration also constantly changes, thereby causes feed inhomogeneous, this is very unfavorable to precision cutting.
Utility model content
The problem existing for above-mentioned prior art, the utility model provides a kind of front mixing abrasive water jet abrasive mixed assembly system, simple in structure, reliable, and uniform feeding makes abrasive material flow more stable.
To achieve these goals, this front mixing abrasive water jet abrasive mixed assembly system, comprises high-pressure intake pipe one, high-pressure intake pipe two, fluid-conveying pipe, fluidization abrasive material pump orifice, threeway and high-pressure abrasive material tank;
By described high-pressure intake pipe one and fluid-conveying pipe, form U-shaped pipeline, it is inner that this U-shaped pipeline is placed in high-pressure abrasive material tank, the bottom of described U-shaped pipeline is positioned at the bottom of described high-pressure abrasive material tank, and offer fluidization abrasive material pump orifice in the bottom inside of U-shaped pipeline, one side of described U-shaped pipeline is high-pressure intake pipe one, and opposite side is fluid-conveying pipe;
Middle part at described fluid-conveying pipe is provided with threeway, the connection fluid-conveying pipe suitable for reading of described threeway, and the end opening of threeway connects high-pressure intake pipe one, and the side mouth of threeway connects high-pressure intake pipe two.
Further, described U-shaped pipeline bottom the described high-pressure abrasive material tank degree of depth 70%～95% between.
Compared with prior art, the pipeline that this front mixing abrasive water jet abrasive mixed assembly system share abrasive mixed is all placed in the inside of high-pressure abrasive material tank, by threeway, connect high-pressure intake pipe one, high-pressure intake pipe two and fluid-conveying pipe, and in the bottom inside of U-shaped pipeline, offer the fluidization abrasive material pump orifice of opening upwards, simple in structure, reliable, uniform feeding, stable.Jet pump principle and fluidization principle are combined, rely on the rapid flow of water under high pressure, after abrasive material is pumped out, then mix with water under high pressure, thereby make abrasive material flow more uniform and stable.Because traditional front mixing abrasive water jet hybrid mode is subject in tank the impact of amount of abrasive larger, minimizing gradually along with amount of abrasive in abrasive can, feed concentration also constantly changes, thereby causes feed inhomogeneous, and the feed fluctuation of concentration of traditional front mixing abrasive water jet hybrid system can be up to 5%～8%; And hybrid system of the present utility model is due to jet pump principle and fluidization principle are carried out to reasonable combination, thereby make abrasive material flow more stable, feed fluctuation of concentration can be controlled to 1%～2% left and right.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, high-pressure intake pipe one, 2, high-pressure intake pipe two, 3, fluid-conveying pipe, 4, fluidization abrasive material pump orifice, 5, threeway, 6, high-pressure abrasive material tank.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1, this front mixing abrasive water jet abrasive mixed assembly system comprises high-pressure intake pipe 1, high-pressure intake pipe 22, fluid-conveying pipe 3, fluidization abrasive material pump orifice 4, threeway 5 and high-pressure abrasive material tank 6;
By described high-pressure intake pipe 1 and fluid-conveying pipe 3, form U-shaped pipeline, this U-shaped pipeline is placed in high-pressure abrasive material tank 6 inside, the bottom of described U-shaped pipeline is positioned at the bottom of described high-pressure abrasive material tank 6, and in the bottom inside of U-shaped pipeline, offer the fluidization abrasive material pump orifice 4 of opening upwards, one side of described U-shaped pipeline is high-pressure intake pipe 1, and opposite side is fluid-conveying pipe 3;
At the middle part of described fluid-conveying pipe 3, be provided with threeway 5, the connection fluid-conveying pipe 3 suitable for reading of described threeway 5, the end opening of threeway 5 connects high-pressure intake pipe 1, and the side mouth of threeway 5 connects high-pressure intake pipe 22.
Further, described U-shaped pipeline bottom the described high-pressure abrasive material tank degree of depth 70%～95% between, and then make the fluidization abrasive material pump orifice 4 that is opened in U-shaped BOP inner side in this depth intervals, and can make abrasive material flow more stable, feed is more even.
The course of work and the principle of this front mixing abrasive water jet abrasive mixed assembly system are: water under high pressure is divided into two-way before entering abrasive can 6, the high-pressure intake pipe 1 of leading up to flows to abrasive can 6 bottoms, while flowing through fluidization abrasive material pump orifice 4, part high-velocity flow makes this place's abrasive material fluidization, while is because flow velocity comparatively fast forms local depression district around at pump orifice 4, thereby the abrasive flows after suction fluidization is to threeway 5; The high-pressure intake pipe 22 of leading up to directly enters threeway 5, and dilution is brought the fluidization abrasive material of threeway 5 into by high-pressure intake pipe 1, then is flowed out by fluid-conveying pipe 3.
This front mixing abrasive water jet abrasive mixed assembly system is simple in structure, reliable, and uniform feeding, stable, combines jet pump principle and fluidization principle, rely on the rapid flow of water under high pressure, after abrasive material is pumped out, then mix with water under high pressure, thereby make abrasive material flow more stable.
