Technical field
The utility model relates to a kind of noiseless switched system of feeding pump, especially relates to the noiseless switched system of feeding pump in a kind of long distance high-voltage Slurry Pipeline Transportation field.
Background technique
Feeding pump is the key equipment in long distance high-voltage Slurry Pipeline Transportation field, and it belongs to centrifugal pump type.Feeding pump system is for long distance high-voltage Slurry Pipeline Transportation technology field, and existing technological design adopts the using and the reserved control principle, and a set of equipment normally moves, and another set of device standby is for subsequent use.When the equipment of normal operation breaks down, stand-by equipment can come into operation immediately, ensures that upstream device normally moves and avoids next procedure to produce and pauses.Moreover the existence of stand-by equipment can be faulty equipment and wins the valuable repair time.
If Fig. 1 is existing feeding pump system delivery technology switching figure, its working method is as follows:
1,, when feeding pump A slurry body, its supporting valve state is: the valve in open mode has: valve A2, valve B3, valve C5 and valve D6; Valve in closed condition has: valve E8, valve F9 and valve G11.In feeding pump A slurry body process, break down and need switch to stand-by feeding pump B operation time, existing switched system operating procedure has:
(1) cut water: open valve E8, clean waterpump 12 is inputted clear water; Throttle down A2, stop supplies slurry.
(2) cut pump: clean waterpump 12 is opened valve F9 after inputting clear water and rinsing well to feeding pump A for approximately 10 minutes, start feeding pump B to normal, open valve G11; Then throttle down C5, stops feeding pump A, throttle down B3.
(3) cut slurry: open valve A2, throttle down E8, recovers slurry body.
The switching of valve, the start and stop of equipment, completing of existing whole feeding pump switched system operating procedure needs 15～20 minutes consuming time.
In like manner, feeding pump B slurry body breaks down and need switch to stand-by feeding pump A operation time, its handover operation step is all: cut water, cut pump, cut slurry.
2,, when feeding pump A carries water, its supporting valve state is: the valve in open mode has: valve E8, valve B3, valve C5 and valve D6; Valve in closed condition has: valve A2, valve F9 and valve G11.Feeding pump A carries and in the process of water, breaks down and need switch to stand-by feeding pump B operation time, existing switched system operating procedure is only cut pump: open valve F9, start feeding pump B to normal, open valve G11; Then throttle down C5, stops feeding pump A, throttle down B3.
Feeding pump system is carried to switch in the process of water and is not related to step and cut water and cut slurry, and the slurry in pipeline, feeding pump equipment of tracing it to its cause when carrying water is rinsed well.While carrying water, handoff procedure only needs to cut pump, therefore handoff procedure only needs 5～8 minutes consuming time.
In like manner, feeding pump B carries water to break down and need switch to stand-by feeding pump A operation time, its handover operation step is only cut pump.
Existing feeding pump system carries that to switch technique of crucial importance, is bringing into play the effect that is difficult to substitute, but along with the enforcement of production process, and while facts have proved feeding pump system slurry body, it switches technique and has following defect:
1, handoff procedure relates to and cuts water, cuts pump, cuts slurry, complex steps; The switching of valve, the start and stop of equipment, complicated operation.
2, cut online water and rinse feeding pump system, sparge water is directly inputted to pressurization main pump, main pipeline, reduces the operating rate of pressurization main pump slurry body, disturbs the concentration of main pipeline slurry body.
3, cut water step and need expend tens cubes of sparge waters at every turn, this sparge water of tens cubes is input to pressurization main pump and is transported to next stage pumping plant and needs sky high cost, and cuts water step remote-effects pressurization main pump and carry less the slurry of tens cubes, extremely uneconomical.
