Description

A kind of horizontal foam pump
Technical field
The present invention relates to pumping unit field, particularly a kind of horizontal foam pump.
Background technology
In ore dressing and metallurgy industry, often require that centrifugal pump conveys some three-phase flow mediums for containing solid, liquid, vapour, most often See be ore dressing flotation operation produce foam.If vapor content in medium (vapor content refers to the volume ratio in medium shared by air) compared with It is few, and the continuation of foam short (i.e. foam can rupture in the short period of time), technique can also be met from common Pulp pump Require；But if vapor content is higher in medium, and the continuation of foam is long, and cannot generally meet technique from common Pulp pump will Ask.Modal phenomenon is flow, lift and the efficiency of pump far below operating mode when design load or conveying clear water.Its reason is： A large amount of steam bubbles that medium contains, can be constantly swollen due to the pressure subatmospheric in medium before into suction eye Swollen, closer to suction eye, steam bubble expands bigger, makes pump just generate serious cavitation when flow is far below design discharge Phenomenon, so as to the flow, lift and the efficiency that cause pump are substantially less than design load, simultaneously because the generation of cavitation phenomenons, common slag The antifriction alloy flow passage part of stock pump shows to produce cellular cavitation hole, and causes flow passage part initial failure, under such conditions, Foam pump must be adopted.
When ore dressing foam class medium is conveyed, in addition to cavitation, another factor is likely to cause the flow of pump, lift to show Write and decline, here it is oppositely oriented with the impeller annular flow between two blades of the circulation phenomenon in impeller, i.e. medium.This Planting annular flow not only causes the efficiency of pump to decline, while also making the flow reduction of pump.From the angle for reducing circulating loss, blade Quantity it is The more the better because blade is more, the spacing between blade is less, and the circulation scale between blade is less, circulation Caused energy loss is less.But in practice, the blade quantity of clarified water pump is usually no more than 10, the number of blade of Pulp pump Amount is usually no more than 7, and its reason has at 3 points, first technological reason, and blade is too many, can bring very big difficulty to technique, its Two is that blade is more, and friction loss is bigger, and excessive blade can cause the efficiency of pump to be remarkably decreased, therefore the quantity of common blade In 3-10 pieces.For foam pump, due to the poor fluidity of medium, blade also results in the section of impeller throat too much and reduces, Mutually squeeze between blade and feed not freely, to avoid the occurrence of such case, the blade quantity of foam pump generally 3-5 is low In clarified water pump or the blade quantity of Pulp pump, this causes the circulation of foam pump even more serious compared with other centrifugal pumps.
As ore dressing foam is a kind of three-phase flow, the difference in specific gravity of vapour phase proportion therein and solid phase and liquid phase is very big, ring Stream effect causes medium to produce classification between the blades, and solid particle and liquid are larger due to proportion, under the influence of centrifugal force The outside of ring is thrown to, and gas forms air mass then due to the less middle part that ring is wrapped in by liquid and solid particle of proportion.Such as The air content of fruit medium is high, then big air mass can be formed in blade, it is difficult to discharge.Pump interruption can be caused when serious to occur disconnected Stream, makes the conveying capacity of pump further decline, therefore, impact of the circulation to foam pump is not only efficiency decline, and which is to flow Affect more much greater than other centrifugal pumps.
Because of a little, the problems referred to above that foam pump is solved, it is necessary to set about from the following aspects, the knot of first improvement pump Structure, makes medium easily enter impeller, and which two is material manufacture flow passage part using anti-cavitation, this is because in above-mentioned operating mode, Cavitation phenomenons is inevitable, it is necessary to just can guarantee that the life-span of pump using the good material of anti-cavitation performance.Which three is to take measures, Mitigate the circulation phenomenon reduced in blade while blade exclusion phenomenon.
