The course of work is as follows: first start whole system, comprise various pump and PLC control system, the front latent husky pump 12 adopted in sand ship is for subsequent use, that is two are used for one, front latent husky pump 12 and the first latent husky pump 17 are started working, water enters the first latent husky pump 17 together with the silt slurries of bed surface, and is outwards delivered to inlet channel 24 or shaped mortar pool 31 by outer defeated sediment delivery pipe 18; Along with the minimizing of bed surface silt, when the dried up lower bed surface of suction inlet of the first latent husky pump 17 is too far away, the first latent husky pump 17 is made to decline respectively by hoist engine 15, the first suction inlet of diving husky pump 17 is made to remain close with bed surface, to keep inhaling husky continuity, when reaching certain depth, when sand can not inhaled again by front latent husky pump 21, then move sand dredger and excavate.

Flowing into the Yellow River slurry of inlet channel 24 is greater than 2m/s speed with flow velocity enters in mortar jar 22 along the tangential direction of the first mortar jar 22 inwall, and slurry, under the effect of its inertia, is forced to do hoop rotary motion after running into the first mortar jar 22 inwall.Sand grain in slurry under the influence of centrifugal force, moves along the first mortar jar 22 inwall as hoop.Due to suffered centrifugal forcedifference, suffered by the solids crude particle in slurry centrifugal forcegreatly, can overcome hydraulic resistance and move to the first mortar jar 22 inwall, and under the acting in conjunction of self gravitation, move downward along mortar jar 22 spiral inner wall, thin and little particle and most of water are then because of suffered centrifugal forceless, do gyration along the frustum of a cone 23 with slurry.At grade, in the first mortar jar 22, velocity flow profile is: the nearly frustum of a cone 23 flow velocity is less, and away from the frustum of a cone 23 near the first mortar jar 22 inwall place, flow velocity is maximum.Under the promotion of follow-up feed, slurry continues downwards and gyration, so coarse granule continues to periphery concentrate, fine particle then rests on central area, and grain diameter is increasing to inwall by center, forms hierarchal arrangement.Along with slurry to flow to the bottom of the frustum of a cone 23 from the top of the first mortar jar 22, flowing sectionmore and more less, flow velocity becomes large, at slurry systolic pressureunder compeling, the water contained in slurry has to change direction, then move upward along the frustum of a cone 23, form inward eddy, because flow velocity is relatively little, if there is sand grains, then under gravity, continue to make subsiding movement downwards to cylinder bottom place, the water that the first mortar jar 22 internal upper part divides is then for sand content is less than 5kg/m ³intimate clear water, this part water through overflow pipe 25 from overflow discharge, become overflow, flow back to the Yellow River.Big particle then continues to move downward along spiral inner wall, forms contour stealth, finally enters feed tank 27 by effluent conduit 26.

Because bottom the frustum of a cone 23, effluent conduit 26 flow q is less than inlet channel 24 flow Q ₁, the unnecessary water yield then makes slow swirling motion upwards to the frustum of a cone 23 top along the frustum of a cone 23 outer diameter face, leaks through overflow pipe 25, and its flow is Q ₂, i.e. Q ₁=q+ Q ₂.

Control its water level or flow by the gate valve adjusting overfall, the concentration regulating effluent conduit 26 sand content bottom overflow pipe 25 flow and the frustum of a cone 23 can be reached.

If collect husky pond, sand dredger carries the Yellow River slurry come up to enter slope kerve formula inlet channel 32 from left bank by the sediment delivery pipe buried underground, because slope kerve formula inlet channel 32 cross-section of river increases, flow rate of water flow obviously slows down, by 2m/s, be down to 0.5m/s, first larger coarse grained sediment settlement on the water inlet hipped end bottom surface of slope kerve formula inlet channel 32, and deposits in husky well 321 along bottom surface, slope to funnel collection; Fine grain silt is then deposited on the water outlet hipped end bottom surface of slope kerve formula inlet channel 32, and deposits in husky well 321 along bottom surface, slope to funnel collection; Small part fine grained is then discharged from catch-drain 38 under the control of control of export lock 33.

In the husky well of funnel collection, the sand of 321 depositions is drawn into outer conveyance conduit by slush pump 37 under the effect of feeding sediment transport pump 36.In feeding sediment transport pump 36 course of work, control the sand content of the slurry from the conveying of feeding sediment transport pump 36 by landing control device 35.

One-level booster station is entered from Ji Shachi or the dense device of silt denseer slurry out, if vertical hydraulic mud pump with plunger, in advance from injected clear water in side-entrance 59 downwards cavity 55, by the first opened type heat radiation position indicator 511, upper plenum 54 is filled water, slurry enters in pump from side-entrance 59, when the first hydraulic jack 512 drives piston boit 58 to move upward, negative pressure is formed in the second mortar jar 51, outlet unidirectional gravity force ball valve 53 is under the differential pressure action of side outlet 510 and the second mortar jar 51, start to move downward, side outlet 510 is by shutoff, import one-way floating ball valve 52 is under the pressure effect of the slurry from sediment delivery pipe, start to move downward, side-entrance 59 is opened, slurry enters in the first mortar jar 51, consider position device 518 gradually by jack-up, the few slurry entering the first mortar jar 51 mixes with clear water, form Hun Jiang district 516.

When the first hydraulic jack 512 drives piston boit 58 to move downward, promote the water of extruding clear water zone 515, water is squeezed, as the transmission medium to slurry transferring energy, slurry is extruded, pressure increase in second mortar jar 51, import one-way floating ball valve 52 is caused to move to supplied materials direction, block side-entrance 59, make slurry can not enter in the second mortar jar 51, simultaneously, slurry in second mortar jar 51 can not export mortar to feed tank 27 or sediment delivery pipe, outlet unidirectional gravity force ball valve 53 moves upward and to be opened by side outlet 510, slurry in second mortar jar 51 flows out to outer row's sediment delivery pipe from side outlet 510.

In piston boit 58 motion process, understand frictional heat and receive the heat dispersed from the first hydraulic jack 512, piston boit 58 is generated heat, affect the stable of pump operation and operating efficiency, water in upper plenum 54 now can play the effect of cooling piston post 58, the stable operation of maintenance equipment, the water that the first opened type heat radiation position indicator 511 is also conducive in lower cavity 55 simultaneously outwards dispels the heat in time.

The reciprocating motion of piston boit 58, annular brace sealing ring 7 is worn, sealing is deteriorated, after annular brace sealing ring 57 weares and teares, clear water can be made to mix, and mortar enters upper plenum 54, annular brace sealing ring 57 can be worn further, and the water level at this moment in the first opened type heat radiation position indicator 511 will rise, thus reminds operating personnel to change annular brace sealing ring 57 in time.

If vertical hydraulic inner tube of a tyre slush pump, in advance two of plunger type water vat 65 chambeies are all filled water, and the liquid level in the chamber on the right will arrive in the second uncovered heat radiation position indicator 610, water now in the cavity of the left side also enters the cavity between the 3rd mortar jar 61 inwall and the mortar inner tube of a tyre 64, when the output of the second hydraulic jack 611 drives plunger 68 to move to oil cylinder direction, negative pressure is formed in the 3rd mortar jar 61, second exports one-way floating ball valve 63 in the 3rd mortar jar 61 outlet with under the differential pressure action of the 3rd mortar jar 61, start to the 3rd mortar jar 61 direction motion, 3rd mortar jar 61 exports by shutoff, second import one-way floating ball valve 62 is under the pressure of the slurry from feed tank 27 or sediment delivery pipe, start to move downward, 3rd mortar jar 61 import is opened, slurry enters in the mortar inner tube of a tyre 64, the mortar inner tube of a tyre 64 is slowly heaved,

When plunger 68 is to the 3rd mortar jar 61 direction motion, promote the water in squeezing rod plug water vat 65, water is squeezed, as the transmission medium to the mortar transferring energy in the mortar inner tube of a tyre 64, the mortar inner tube of a tyre 64 is extruded, interior pressure increase in the mortar inner tube of a tyre 64, the second import one-way floating ball valve 62 is caused to move to supplied materials direction, block the import of the 3rd mortar jar 61, make slurry can not enter in the mortar inner tube of a tyre 64, slurry simultaneously in the mortar inner tube of a tyre 64 also cannot overflow to supplied materials direction, second outlet one-way floating ball valve 63 moves downward to be opened the 3rd mortar jar 61 outlet, slurry in the mortar inner tube of a tyre 64 flows out from outlet.

Because of frictional heat and the heat dispersed from the second hydraulic jack 611 can be received in plunger 68 motion process, plunger 68 is generated heat, affect the stable of pump operation and operating efficiency, water in plunger type water vat 65 now can play the effect of cooling plunger 68, the stable operation of maintenance equipment, the water that the second uncovered heat radiation position indicator 610 is also conducive in plunger type water vat 65 simultaneously outwards dispels the heat in time.

The reciprocating motion of plunger 68, sealing ring 67 between plunger 68 and plunger type water vat 65 is worn, sealing is deteriorated, after sealing ring 67 weares and teares, the water in the chamber on the left side of plunger type water vat 65 can be made to flow in the chamber on the right, at this moment the water level in the second uncovered heat radiation position indicator 610 will rise, thus reminds operating personnel to change sealing ring 67 in time.

Flow through sediment transport through pipeline surge tower from one-level booster station slurry out through sediment delivery pipe and then enter two-stage pressurizing pumping plant, finally insert subsidence area, when one-level pumping plant normally work, secondary pumping station break down time, the water sand carried by sediment delivery pipe 41 will be moved upward by erectting pipeline 42, along with increasing in water sand, pressure increase in sediment delivery pipe 41, the water sand exceeding secondary pumping plant transportability of sediments is discharged in reservoir 44 by erectting pipeline 42, alleviates the pressure in sediment delivery pipe 41; When the water level in reservoir 44 exceedes Liquid level display, draining valve 46 is opened, and the water in night cylinder is drained into automatically planning region; When secondary pumping station normally works, and one-level pumping plant is when breaking down, defeated slurry quantity not sufficient in sediment delivery pipe 41, when not reaching design slurry body amount, pressure in sediment delivery pipe 41 reduces, erect the husky slurry amount of supplementing and lacking that will lower of water in pipeline 42, now the pressure erect in pipeline 42 will correspondingly diminish, stop valve 45 reverse time automatically to open under the effect of pressure reduction, the water in reservoir 44 flows out, and adds in sediment delivery pipe 41, simultaneously, submersible pump 48 works, and maintains the liquid level in reservoir 44, ensures that secondary pumping station is carried according to design discharge.
