2During two water pump 22 tandem workings, the increase of the pressure of vacuum chamber 4, the pressure that last sand is chewed 5 inside and outside generations increases, and last sand is chewed 5 suction increase, and last sand is chewed 5 husky the measuring greatly of adopting.
Adopt the mode of relay pump 22 to increase pressure, sand is chewed 5 the husky output of adopting in the increase, can select low power generating equipment 21 and water pump 22 for use, energy-conserving and environment-protective, and it is little to take volume, can reduce the volume and the displacement tonnage of hull.
Particularly, the said sand tube group 6 that goes up comprises mixing tube 61, anemostat 62 and last sand tube 63, and said mixing tube 61 is connected with said vacuum chamber 4, said anemostat 62 respectively, said anemostat 62 with said on sand tube 63 be connected.
In use, water pump group 2 can be constantly with in the current suction clear water pipe 3 at a high speed, when current at a high speed pass through nozzle 7 ejections; Vacuum chamber 4 can be near vacuum state, makes that going up sand chews the bigger pressure reduction of 5 inside and outside generations, thereby forms strong suction; The silt at the bottom and water are drawn into sand together chew in 5, and successively through vacuum chamber 4, mixing tube 61, anemostat 62, in the entering in the sand tube 63; Last sand tube 63 with wash Sha Chi and be connected; At last, mix silt and wash Sha Chizhong, reach and take out husky purpose with current inflow at a high speed.
The said generating equipment 21 of present embodiment is a diesel-driven generator, and said diesel-driven generator comprises diesel engine, generator and motor, and said diesel engine is connected with said generator, and said generator is connected with said motor, and said motor is connected with said water pump 22.
The optional power that uses of Diesel engine is 110KW or above Diesel engine, reduces cost of investment and operating cost, can also reduce volume, the displacement tonnage of hull.
The said generating equipment 21 of present embodiment can or be a natural gas engine for heavy fuel burning engine also.
During mostly heavy fuel burning engine is, low-speed generator, mainly contain running cost low, can be for a long time advantage such as operation and reliable, long service life and low noise continuously.
It is wide that natural gas engine has output power range; Advantages such as startup and reliable height, power generating quality is good, maintenance is simple, low-frequency noise is little; Because natural gas is a kind of environment-protecting clean energy, can reduce the pollution to environment, the running cost of natural gas engine is lower than heavy fuel burning engine.
Generating equipment 21 is not limited to above-mentioned three kinds, can select different types according to the demand of producing.
As shown in Figure 2, the difference of present embodiment and embodiment 1 is: the said water pump group 2 of present embodiment is three groups, and three water pumps 22 of three groups of water pump groups 2 are connected in series.
During three water pump 22 series connection, Q
String=Q
1=Q
2=Q
3, H
String=H
1+ H
2+ H
3, and H=P/ ρ (ρ is the density of water, 1000kg/m
3), can know P
String=P
