The pressure difference that device is the self weight and equilibrium water road by abrasive material is inhaled, abrasive material is made to enter the mixing chamber positioned at high-pressure abrasive material tank lower part
It is mixed with high pressure water.But since this hybrid mode is affected by amount of abrasive in tank, with amount of abrasive in abrasive can
Gradually decrease, feed concentration also constantly changes, to cause feed uneven, this is very unfavorable to accurate cutting.Due to passing
System front mixing abrasive water jet hybrid mode is affected by amount of abrasive in tank, and in abrasive can, amount of abrasive gradually subtracts
Few, feed concentration also constantly changes, to cause feed uneven, the feed of traditional front mixing abrasive water jet hybrid system is dense
Degree fluctuation up to 5%~8%.

Pipe end is stretched out outside high-pressure abrasive material tank, and first high-pressure intake pipe is equipped with fluidization abrasive material pump orifice, and fluidization abrasive material is taken out
First high-pressure intake pipe of suction inlet water outlet side is equipped with water pump.
Preferably, the first high-pressure intake pipe between the water pump and fluidization abrasive material pump orifice be equipped with the second high pressure into
Water pipe.
Preferably, the fluidization abrasive material pump orifice is arranged in high-pressure abrasive material tank 80%~90%.
Preferably, sealing material is equipped between the water inlet and the first high-pressure intake pipe.
Preferably, the fluidization abrasive material pump orifice includes the first fluidization abrasive material pump orifice, the second fluidization abrasive material pumping
Suction inlet, the first fluidization abrasive material pump orifice, the second fluidization abrasive material pump orifice are set gradually from water (flow) direction, the first fluidization mill
Expect pump orifice, the second fluidization abrasive material pump orifice towards on the contrary.
Compared with prior art, the invention has the following advantages:
First, the present invention, which innovatively increases water pump in high-pressure intake pipe water part, is, water pump cooperation connects two pump orifices, makes
The suction for obtaining abrasive material is more stable.
Second, fluidization abrasive material pump orifice includes the first fluidization abrasive material pump orifice, the second fluidization abrasive material pump orifice, the
One fluidization abrasive material pump orifice, the second fluidization abrasive material pump orifice are set gradually from water (flow) direction, the suction of the first fluidization abrasive material
Mouthful, the second fluidization abrasive material pump orifice towards on the contrary, aspirated for the abrasive material of both direction in high-pressure abrasive material tank, improve
Pumping efficiency, structure is simple, reliable, uniform feeding, stabilization.Jet pump principle and fluidization principle are combined, by high pressure
The quick flowing of water after pumping out abrasive material, then is mixed with high pressure water, to make the more uniform stabilization of abrasive material flow.
Third, and hybrid system of the invention is due to carrying out reasonable combination for jet pump principle and fluidization principle, thus
Keep abrasive material flow more stable, it can be by feed fluctuation of concentration control 1%~2% or so.
