Abstract
The utility model relates to a large flow double turbine shroud long distance oil transmission pump, belonging to the field of pump product. An interval of 8 to 20mm is reserved between the internal sidewall of partition tongue of double turbine shroud and the external circular edge of impeller, and the blade outlet angle of impeller is 27 to 35 DEG; the pump can be suitable and meets the transportation requirements of viscous oil liquid, and can bear and finish the transportation operation of good fluidity liquid as fresh water, muddy water, etc. The utility model has the advantages of extensive application scale, strong adaptability, large flow rate, long transportation distance and high efficiency.
Description
Technical field
The utility model belongs to the pump series products, is mainly used in the conveying operation of fluids such as oils liquid and clear water.
Background technique
The multistage fractional centrifugation pump of two volute single suctions is one of important pump type of current conveying clear water and similar clear water liquid, mainly is suitable for field irrigation, factory and city water; Because this pump noise in operating is less, is particularly suitable for the water supply of tall building and hotel again and uses.But because the deficiency on its structural design, this pump can not adapt to and satisfy the mobile relatively poor conveying such as crude oil class liquid, its application area is narrowed down, and such pump duty is little, and lift is low, bad adaptability.
Summary of the invention
The purpose of this utility model is exactly technical problem and the shortcoming that exists at the existing pair of multistage fractional centrifugation pump of volute single suction, design provides the two volute length of a kind of big flow apart from oil transfer pump, by redesign, reach and improve this pump duty, lift and efficient, expansion adaptability, satisfied long apart from the purpose of carrying needs thick liquid such as crude oil class product to its impeller blade exit angle and impeller and two volute cut water gaps.
Basic design of the present utility model is, is provided with 8-20 millimeter gap between the baffle tongue end internal face of two volutes and circumference of impeller outward edge, and the blade outlet angle of impeller is 27 °-35 °.
The utility model had both satisfied the conveying requirement than the toughening oil class I liquid I, can finish liquid such as clear water, muddy water again and carry, and had the advantages that using scope is wide, adaptive capacity is strong, flow is big, fed distance is long, efficient is high.
Description of drawings
Fig. 1 is that the two volute length of big flow are apart from the oil transfer pump structural representation;
Fig. 2 is the side direction view of Fig. 1.
Piece number explanation among the figure:
1, two volutes, 2, cut water, 3, impeller, 4, blade.
Embodiment
Below in conjunction with accompanying drawing the utility model optimum implementation is described in detail.The two volute length of big flow comprise two volutes 1 apart from oil transfer pump and are fitted in impeller 3 in two volutes 1, and being provided with H between the cut water 2 tongue end internal faces of two volutes 1 and impeller 3 circumferential outer edges is the 8-20 mm clearance; The blade 4 exit angle α of impeller 3 are 27 °-35 °.
During operation, liquid enters in the impeller 3 through impeller 3 oilers, and the impeller of rotation 3 drives blade 4 liquid is discharged fast, and through cut water 2 outsides of two volutes 1, enters in next stage impeller 3 and the two volutes 1, carries step by step, outside the last excavationg pump, finishes conveying.Enough big and reasonably under angle of impeller outlet alpha and impeller and H effect of cut water gap and the assurance, make the oils liquid reliable delivery of thickness.This pump hour flow can reach more than 800 tons, promotes about 800 meters of lift.
