Abstract
The utility model relates to a hydraulic submersible step pump, which belongs to the machinery for irrigation and drainage and aims at solving the problems that the existing centrifugal pump has shallow suction lift, the existing axial-flow pump is bulky with high cost, and the existing submersible pump can not be conveniently used in areas without power supply. The utility model is composed of two independent individuals of a centrifugal pump and a hydraulic submersible pump which are connected as a whole through a water delivery pipe. The hydraulic submersible step pump has a delivery lift of 40 meters and a suction lift of 45 meters, and has the advantages of small size, light weight, low function to price ratio, long service life, and high stability and reliability. The hydraulic submersible pump is more suitable for working under inflammable and explosive environment. The motive power matched with the utility model is a single apparatus or an apparatus matched with farm motive power machines, electromechanical machines and hydraulic machines. The hydraulic submersible step pump is applied to water supply and drainage projects of wells, ponds, channels, and rivers, can pump and drain liquids with similar physical and chemical performance with water, and is particularly suitable for water-saving and energy-saving irrigation facilities for sprinkling irrigation, etc. in agriculture.
Description
The utility model belongs to the mechanical facilities of irrigation and drainage in the farm machinery, is applied to that farmland water-saving is irrigated and city industrial and mining enterprise supply water, draining, also is used for the novel hydraulic diving ladder pump of the row's of giving engineering at inflammable and explosive environmental work place.
At present, existing drainage and irrigation equipment mainly contains: centrifugal pump, axial-flow pump, Submerged Motor Pumps, twin-stage flexible axle pump, clutch type soft and hard shaft multiple pump, soft axle deep-well pump, the characteristics that the structure of these several pumps, use respectively have, and the narrow limitation of application area, deficiency place and the economic degree used, concrete condition is:
1, centrifugal pump.Be made of the pump housing and impeller etc., its feature is: can obtain higher lift and power usage mode easily, but it is low to inhale journey, only is 8-9 rice.Because the inequality of the level of ground water depth, and level of ground water descends gradually, the demand that is difficult to conform, and the diversion or make the pump housing with machinery type and be full of water among the suction pipe down of should annotating before starting centrifugal pump is used inconvenient.
2, axial-flow pump.Be made of transmission shaft and subordinate's water pump, its feature is: subordinate's pump directly enters in the water, and the diversion of need not annotating during startup makes water pump only have lift, also both for the down-hole pumpage strengthens, can locate work than the deep water position.But its equipment is heavier and complicated, move, install all inconvenient, when doing power with diesel engine, must use the halved belt transmission, not only work efficiency is low, and is absolutely unsafe, starting is very required great effort during diesel engine (during because of the starting machine, driven transmission shaft and impeller again simultaneously, driven the water acting simultaneously), even can not realize its function.
3, Submerged Motor Pumps.Form by water pump and motor, its feature is: the pump housing and motor directly pull the plug, and there is not the suction journey in it, only have lift, it is comparatively convenient to use in the sufficient area of electric power, in the areas without electricity place that water saving irrigates such as maybe need spray, not the investment that increases corollary equipment, be exactly the price height of Submerged Motor Pumps itself, and safeguard inconvenient, life-span also is subjected to the influence of electrical network situation and working environment bigger, and maintenance expenses is had high input, and influence is extensively promoted.
4, twin-stage flexible axle pump.Be made up of centrifugal pump and subordinate's pump, centrifugal pump is connected by flexible axle with the subordinate pump, and power drives subordinate's impeller by flexible axle and successively supplies water.Its feature is: when guaranteeing that integral pump has higher lift, increased the suction journey of pump again.Integral body has adopted the wire soft shaft transmission of 10-12 rice, and efficient is lower, and cost is higher, and weight is big, moves inconveniently, when doing power source with diesel engine, in the starting diesel engine, has also done the merit of water lift, the phenomenon of diesel engine that starting arranged not sometimes.
5, clutch type soft and hard shaft multiple pump.Constitute by clutch, centrifugal pump, flexible axle and subordinate's axial-flow pump etc.Its feature is: some advantages of comprehensive above each pump, increased the convenience of power starting, and guaranteed high-liftly, increased the suction journey, changed the controllability of inhaling journey.Owing to its employing major axis is done transmission component, and efficient is reduced, the equipment complexity is installed inconvenience, along with the increase of suction Cheng Zengjia price is higher, can not bring up to higher degree inhaling journey.Influence the effect of deep water position operation.
6, soft axle deep-well pump.Be made up of wire soft shaft and subordinate's pump, its feature is: subordinate's pump directly enters in the water, has increased the water lift degree of depth, when areas without electricity is used, must use the halved belt transmission, has reduced safety reliability, and efficient coaxial flow pump is the same lower.The phenomenon that has also had simultaneously the inconvenience of diesel machine.Invar silk flexible axle is difficult for oversize, and the water lift degree of depth is also very limited.
The purpose of this utility model is to overcome the deficiency of above prior art, can be applicable in the irrigation installation such as water-saving spray to have the lift height, inhale Cheng Shen, the life-span is long, can separate combination and provide a kind of, compact structure, volume is little, and is in light weight, stable and reliable working performance, the efficient height, there have areas without electricity to use to be all economical, is convenient to operation under the inflammable and explosive environment, uses hydraulic pressure diving ladder pump easy to maintenance.
Formation of the present utility model:
