Description
Technical field
The present invention relates to water pump field.
Background technology
Water pump is the machinery for conveying liquid or being pressurized liquid.It transmits the mechanical energy of prime mover or other external energies
Liquid, increase liquid energy, being mainly used to conveying liquid includes water, oil, acid ＆ alkali liquid, emulsion, suspended emulsion and liquid gold
Category etc..
Centrifugal pump：Before water pump starts, pump and water inlet pipe are first filled into water, after pump operation, impeller at a high speed rotation and produce
In the presence of raw centrifugal force, the water in impeller channel is thrown toward surrounding, is pressed into spiral case, and impeller eye forms vacuum, pond
Water is inhaled into supplemented with this space under external atmospheric pressure along suction hose.Then the water sucked is thrown away through spiral case by impeller again
And enter outlet pipe.As can be seen here, if centrifugal pump impeller constantly rotates, it can continuously absorb water, press water, water can be continuously
Raised from lower to eminence or a distant place.In summary, centrifugal pump is due to the work of centrifugal force caused by the high speed rotation in impeller
Under, water extraction is hoisted, therefore claims centrifugal pump.The general characteristic of centrifugal pump：Water is along impeller along the direction that flows through of centrifugal pump
Axial direction suction, perpendicular to axial outflow, that is, it is mutually in 90 ° to pass in and out water (flow) direction.Because centrifugal pump is by impeller inlet formation vacuum
Water suction, therefore into pump and diversion must be irrigated in suction hose in prestart, or be evacuated with vavuum pump, formed very with discharging air
Sky, and pump case and suction line must be sealed strictly, must not gas leakage, otherwise can not form vacuum, also just do not inhale water.Due to
Impeller inlet is not likely to form absolute vacuum, therefore centrifugal pump suction head flows through suction line no more than 10 meters plus water
The linear loss brought, actual allowabler mounting height（Height of the water pump axis away from the suction water surface）Much smaller than 10 meters.Such as installed
Height, then do not absorb water；Further, since mountain area is lower than Plain atmospheric pressure, therefore same water pump be in mountain area, particularly in alpine region
During installation, its setting height(from bottom) should reduce, and otherwise can not suct water.
Axial-flow pump, the operation principle and feature of axial-flow pump, axial-flow pump is different from the operation principle of centrifugal pump, and it is mainly sharp
The thrust water lift caused by the high speed rotation of impeller., can be water under to lift caused by water when axial flow pump blade inner rotates
Side shifts top onto.
The blade of axial-flow pump is typically immersed in by the pond in water suction source.Because impeller rotates at a high speed, caused by blade
Under lift effect, continuously water is pressed upwards on, water is flowed out along outlet pipe.Impeller is constantly rotated, and water is also just connected
It is continuous to be sent to eminence.The general characteristic of axial-flow pump, water are along the axial direction suction of impeller, axially stream in the direction that flows through of axial-flow pump
Go out, therefore claim axial-flow pump.Lift is low（1~13 meter）, flow is big, high efficiency, suitable for Plain, lake region, river reach irrigation and drainage.Prestart is not
It need to pour water, it is simple to operate.
The operation principle of mixed-flow pump, because the impeller shape of mixed-flow pump is between centrifugal pump impeller and axial-flow pump impeller,
Therefore, the existing centrifugal force of the operation principle of mixed-flow pump has lift again, and by both comprehensive functions, water with axle then to form certain angle
Degree outflow impeller, hoists water extraction by volute chamber and pipeline.The general characteristic of mixed-flow pump, mixed-flow pump compared with centrifugal pump,
Lift is relatively low, and flow is larger, and compared with axial-flow pump, lift is higher, and flow is relatively low.Suitable for Plain, lake region irrigation and drainage.Water is along mixed flow
Pump to flow through direction and impeller axle angled and suck and outflow, therefore also known as diagonal pumps.
The characteristics of high pressure reciprocating pump：
High pressure reciprocating pump, the use pressure of high pressure reciprocating pump typically should be between 10MPa~100MPa.It belongs to positive displacement pump,
Reach the purpose of conveying liquid by the volume cyclically-varying in working chamber；The mechanical energy of prime mover is converted into through pump
Convey the pressure energy of liquid；The capacity of pump is solely dependent upon working chamber volume changing value and its change frequency within the unit interval,
It is unrelated with discharge pressure in theory.Reciprocating pump is the reciprocating motion in fluid cylinder working chamber by means of piston（Or pass through barrier film, ripple
Periodicity elastic deformation of the flexible members such as line pipe in working chamber）It is periodically variable produce working chamber volume.Tying
On structure, the working chamber of reciprocating pump is separated by sealing device and the external world, passes through pump valve（Inlet valve and dump valve）With pipeline ditch
Logical or closure.It is primarily adapted for use in high-pressure low-flow, it is desirable to which the flow of pump is constant or quantifies, proportional a variety of Jie of conveying
Matter, either require that intake performance is good or require the occasion for having self-priming performance.It is past under the situation of world today's energy scarcity
Multiple pump has obtained wide as energy-conserving product in numerous industries such as energy mining, oil fine chemistry industry, food and medicine processing
General use.This kind of pump configuration is more complicated, and matching is strong and poor universality, wide in variety and batch is small.
It can be seen that existing water pump, otherwise be exactly that lift is low（Less than 10 meters）, otherwise be exactly that complicated cost is high.
