Description
Technical field
The invention belongs to long-distance slurry line transportation field, particularly relate to a kind of undisturbed switching method of operating modes of multi-stage pump station.
Background technique
When the long-distance pipe that utilizes hydraulic principle to carry out solid material is carried; Because of tens kilometers at least of fed distance, nearly thousand kilometers at most, therefore in the pipeline way, need to increase a plurality of booster stations and could accomplish the conveying task; And during the line transportation of solid material; The flow velocity of slurry must be controlled in certain scope, so each pumping plant needs play often switching between operating mode at independent operation mode with connecting, because of each high-pressure service pump station owner pump is positive-displacement pump; And such main pump must provide the inlet pressure greater than 300KPa, as is lower than this force value and then causes main pump protection to be stopped.Usually the inlet pressure of line transportation ore pulp is about 800KPa; About will guaranteeing that when switching the ore pulp of feeding pump when main pipe is fed ore pulp also will be for 800KPa; If pressure is inconsistent; Then can build-up of pressure unbalanced not of uniform size the causing of flow that causes ore pulp to be carried finally causes main pump to stop.So in handoff procedure, must guarantee main pump inlet pressure no change.
As shown in Figure 1, when independently excited cavity moved, ball valve FV01, FV03 opened, FV02 closes.When will the company of switching to during the molding formula, need to open FV02, but the FV03 outlet connects pond or stirring chest, with atmosphere,, cause the low protection of main pump inlet pressure to stop so make that main pump inlet pressure is zero after opening FV02.When connecting the molding formula, ball valve FV01, FV02 open, FV03 closes equally.When switching to independently excited cavity, need to open FV03, at this moment causing main pump inlet pressure equally is zero the parking.
Summary of the invention
The present invention has proposed following technological scheme in order to solve the no disturbance switching problem of operating modes of multi-stage pump station.
A kind of operating modes of multi-stage pump station that is used for does not have the energy dissipator that disturbance is switched; Said multi stage pumping station is provided with first ball valve and second ball valve between prime pumping plant and main pump inlet; Between the first ball valve output terminal and stirring chest/pond, be provided with the 3rd ball valve; Between the second ball valve output terminal and feeding pump, be provided with the feeding pump ball valve, said energy dissipator comprises ceramic energy dissipating plate, is arranged on the input ball valve of energy dissipating front edge of board, is arranged on the output ball valve of energy dissipating plate rear end and controls ball valve, wherein imports ball valve and is connected the 3rd ball valve output terminal; The output ball valve is connected stirring chest/pond one end, and the control ball valve is arranged between the 3rd ball valve and the stirring chest.
The invention also discloses and utilize above-mentioned energy dissipator to carry out multi stage pumping station to connect the undisturbed switching method that the molding formula switches to independently excited cavity, specifically: start feeding pump, open feeding pump ball valve, energy dissipating plate input ball valve and output ball valve; The closing control ball valve; Open the 3rd ball valve then, the energy dissipating plate makes that the pressure difference at the 3rd ball valve two ends is zero, closes second ball valve then; Accomplish and switch, guarantee that main pump inlet pressure in handoff procedure does not change.
The invention also discloses and utilize above-mentioned energy dissipator to carry out the multi stage pumping station independently excited cavity to switch to the undisturbed switching method that connects the molding formula, specifically: open energy dissipating plate input ball valve and output ball valve, closing control ball valve; Start feeding pump, open the feeding pump ball valve, open the 3rd ball valve; The energy dissipating plate makes that the pressure difference at the 3rd ball valve two ends is zero, closes second ball valve then, opens the control ball valve; Accomplish and switch, guarantee that main pump inlet pressure in handoff procedure does not change.

Embodiment
Below in conjunction with accompanying drawing the present invention is specifically described.
As shown in Figure 2; Between prime pumping plant and main pump inlet, be provided with the first ball valve FV01 and the second ball valve FV02; Between the first ball valve FV01 output terminal and stirring chest/pond, be provided with the 3rd ball valve FV03, between the second ball valve FV02 output terminal and feeding pump, be provided with feeding pump ball valve FV04, the present invention increases by a cover energy dissipator 1 in ball valve FV03 rear end; Shown in frame of broken lines part among the figure, this energy dissipator 1 comprises ceramic energy dissipating plate 2, inlet opening ball valve FV06 and delivery outlet ball valve FV07.Utilize energy dissipating plate 2 to make the isostasy at energy dissipating plate 2 two ends.Simultaneously, between ball valve FV03 and stirring chest, increase by a control ball valve FV05.
When even the molding formula switches to independently excited cavity, start feeding pump 3, open FV04, FV06, FV07; Close FV05, open FV03 then, the inlet pressure of line transportation ore pulp is about 800KPa usually; This moment, the ore pulp of the 800KPa that energy dissipator 1 will transport from main pipe carried out energy dissipating, thereby made energy dissipating plate pressure at two ends balanced, and the pressure difference at FV03 two ends is zero; Close FV02 this moment, guaranteed that main pump inlet pressure in handoff procedure does not change.
Switch to Lian Dashi at independently excited cavity, open FV06, FV07, close FV05; Start feeding pump 3, open FV04, open FV03; Same effect owing to energy dissipating plate 2, the pressure difference at FV03 two ends is zero, closes FV02; Open FV05, switch and accomplish, guaranteed that main pump inlet pressure in handoff procedure does not change.
In a word; No matter connecting the molding formula, to switch to independently excited cavity still be that independently excited cavity switches to and connects the molding formula; The pressure that has all guaranteed feeding pump 3, energy dissipating plate 2 two ends is consistent with the inlet pressure of main pipe transfer ore pulp; The pressure that promptly guarantees the three all is about 800KPa, thereby has avoided the main pump protection to stop.
