Abstract
The utility model relates to an energy-saving efficient axial-flow pump, belonging to the single-stage half regulating vertical type axial flow pump, which relates to hydraulic machinery. The utility model aims at providing an axial flow pump which has the advantages of advanced structure, good performance, high efficiency, energy saving, high manufacture and assembly precision. The utility model is characterized in that the energy-saving efficient axial-flow pump adopts novel fluid sheets, improves the angles of blades and diffusers, and uses a water rubber bearing instead of an oil rubber bearing. The utility model has the advantages of large flow and high delivery lift, widely being used for agriculture, which provides a reliable machine for harvest assurance in drought and water logging.
Description
The utility model relates to hydraulic machinery, belongs to single-stage and partly regulates vertical-type axial-flow pump.
Existing axial-flow pump remains in following defective in the middle of irrigation and drainage are used:
1, the external PVA-35 axial-flow pump of producing, poor performance, efficient are hanged down and are not reached usage requirement;
2,14 of domestic production " ZLB-70 axial-flow pump, though on performance, improve to some extent,, for the part of most critical---the water inlet and outlet angle of blade and the angle of wing, still design not good enoughly, its flow and lift can not satisfy user's needs.
The purpose of this utility model is at the defective on the prior art, and the energy-efficient axial-flow pump that a kind of flow is big, lift is high, performance is good is provided, for the agricultural high yields irrespective of drought or water logging is contributed.
Formation of the present utility model is made up of rigid coupling (1), Gland (2), filler (3), stuffing box chamber (4), rubber bush bearing (5), Discharging bent-tube (6), pump shaft (7), diffuser (8), impeller base (9), blade (10), locating stud (11), screw rod (12), impeller head (13), tubaeform intake pipe component such as (14).Its turnover water pipe internal diameter is 350 millimeters.And have two best performances, and if the apolegamy motor is 30KW person, then the irrigation and drainage lift can reach 6.5 meters, represents with 350XLB-6, if the apolegamy motor is elected 37KW person as, then the irrigation and drainage lift can reach 7.8 meters, represents with 350XLB-8.
Its improvement characteristics, adopted advanced technology both domestic and external, increase and designed 48 cover special process equipments, the frock coefficient is reached more than 1.3, thereby improved the castability of product and machine adds and assembly precision, make impeller and pump housing matching gap rationally, go slick, runner is smooth, friction factor reduces.Also according to the advanced experience of No. three blades, the design of blade is improved, reduced centrifugal force, increased axial lifting force, reduced backflow, increased following current, thereby the big raising of quality of product.
One of feature of the present utility model is improved the water inlet and outlet angle of blade (10), and blade edge is shortened, and wedge angle is made circular shape.And the installation and the locking device of blade (10) improved, be convenient to blade (10) translation-angle and fastening.
Two of its feature is made streamline with diffuser (9), and the stator angle is improved.
Three of its feature has adopted the rubber bush bearing structure, so both can save valuable metallic material, has opened up again with the new way of water for oil lubrication.
Advantage of the present utility model and good effect:
1, structure advanced person, manufacturing and assembly precision height, its flow improves respectively more than 46.2% and 41.8%.
2, function admirable has been improved the indicatrix of water pump, has enlarged efficient region, hydraulic efficiency is risen to respectively more than 10% and 7%, and make lift bring up to 6.5 meters and 7.8 meters respectively.
3, adopted with the rubber bush bearing of water for oil lubrication.
4, compared with prior art, its performance raising sees table 1 for details.
5, energy saving, the utility model necessary electromotor is respectively 30KW and 37KW, can satisfy water drainage, the drought resisting needs in 3300 mu of farmlands, " flow of XLB-70 axial-flow pump increases by 84 liters/second, irritates the farmland more than 840 mu more; also the water lift height is increased by one meter; respectively by idle, consumption calculations three degree that per hour economize on electricity; operation every day is by calculating 24 degree that then economize on electricity in eight hours; annual operation was calculated by three months; 2160 degree can economize on electricity than existing 14, life-span than 350ZWD type axial-flow pump prolongs more than three times, and one-time investment is few, receives praises from customers.
Description of drawings:
Fig. 1 is a complete machine schematic representation of the present utility model.
(1) is rigid coupling in Fig. 1; (2) be Gland; (3) be filler; (4) be the filler cassette holder; (5) be the rubber axis pump; (6) be Discharging bent-tube; (7) be pump shaft; (8) be diffuser; (9) be impeller base; (10) be blade; (11) be locating stud; (12) be screw rod; (13) be the impeller head; (14) be tubaeform intake pipe.
Embodiment:
The conformity that when making and assembling tubaeform intake pipe (14), diffuser (8), will keep size and precision with Discharging bent-tube (6).When assembling impeller base (9) and blade (10), the wall gap must keep even within its cylindrical and diffuser (8) and the tubaeform intake pipe (14).Rubber bush bearing (5) will must not note and touch oils in the middle of being made, assemble and using.In impeller base (9), require to be carved with number of degrees line, the center should be carved and is zero degree, on the left side carve for+2 ° ,+4 °; Be-2 ° ,-4 ° quarter on the right, and sheet leaf established angle is a zero degree.
Claims (2)
