Description
Technical field
The present invention relates to agricultural water pump technical field, particularly a kind of powershift combined agricultural water pump.
Background technology
Well-known agricultural drainage and irrigation can run into various complex situations: (1) as required within the regular hour agricultureA large amount of irrigation and drainage are carried out in field, and conventional method is to adopt multiple water pumps to work simultaneously, will certainly cause like this moneySource waste, increase equipment and cost of labor; (2) run into crops high-land, and the lower feelings of water source physical featuresCondition, adopts centrifugal multistage pump multiple centrifugal pump to carry; (3) substituting water for cultivation fish pond needs flexible delivery, preventsFry is damaged; (4) immersible pump is more responsive for mud, impurity pasture and water and particle foreign material, need bePump is installed screen pack outward, work a period of time after pasture and water impurity because suction is all adsorbed on screen pack,Thereby cause pump work efficiency low or quit work. Conventional agricultural water pump has centrifugal pump, immersible pump at presentEtc. various ways: centrifugal pump structure is simple, lift is higher, and water yield is little relatively, the machinery effect of water pumpRate is greatly about 70% left and right, and the farmland discharging-irrigating water larger for quantity of sand and mud content exists water pump serious wear,Power consumption is large, when to fish pond water irrigation and drainage, exists fry is damaged to large problem; When having in pump caseWhen air, produce less centrifugal force because the density of the density ratio liquid of air is much smaller, thereby make liquidFace top is not enough to interior liquid to be pressed in pump with the pressure differential at Pump Suction Nozzle place, and centrifugal pump is without from energy-absorbingPower, makes centrifugal pump can not carry the problem of liquid (" air sinuses phenomenon "). Immersible pump and above-mentioned centrifugal pumpCompare, do not have " air sinuses phenomenon ", exterior lower-pump submersible pump directly the pumping chamber from impeller orLiquid, the liquid cools that motor is also pumped are discharged in diffuser exit; Immersible pump is to liquid acting,Mechanical energy is converted to liquid energy, under the effect of centrifugal force, water is discharged, this pump discharge is large, but raisesJourney is very low, and pump efficiency only reaches 68%, and energy resource consumption is larger; In addition, the solid dielectric of pumping is had to oneFixed restriction, insulating requirements is higher, cannot meet high-lift requirement. Two kinds of agricultural water introducing from abovePump can find out, they respectively have pluses and minuses, it is mainly that mechanical efficiency (energy-conservation) is low, poor stability andThe problems such as purposes is single.
The patent of invention that 200710098031.5 of existing patents are called " a kind of spiral flow constant-pressure pump " providesA kind of spiral flow constant-pressure pump, comprise a pump case and an impeller, pump housing endophragm is circular arc, impeller comprisesOne back shroud with a hub portion, be positioned at back shroud front side and the multiple frontal lobes of back shroud shape all-in-one-pieceSheet and be positioned at back shroud rear side and multiple pairs of blades of back shroud shape all-in-one-piece, each front vane is after closeCover plate circular edge place is to counterclockwise bending and to tilting clockwise, with the front surface of back shroudThe bending sloping portion that shape forms an angle, pays blade straight line and extends to impeller outer edge, when this pump rotatesThe vent centrifugal power of bending sloping portion back root part is greater than the vent centrifugal of the front free margins of bending sloping portionPower, the flow stream pressure of back root part is the corresponding flow stream pressure higher than front free margins also, and liquid flow path direction is by back root partPoint to free margins, produce longitudinal flow, form spiral flow along with wheel rotation produces rotational flow, then enterEnter the space between multiple front vanes on impeller, pressurization again, it acts on similar centrifugal multistage pump multiple centrifugal pump, therebyObtain high-lift and constant voltage output.
Although above-mentioned spiral flow constant-pressure pump can reach constant voltage, solid impurity is pumped characteristic, working method andPurposes is single, and it is low that promote liquid efficiency early stage, cannot reach the instructions for use of farmland discharging-irrigating under the slow-speed of revolution.
