Abstract
The invention provides a spiral centrifugal pump. A whole pump body is composed of structural elements designed according to a spiral principle and a centrifugal principle. The spiral centrifugal pump comprises a motor, a pump shaft, a water blocking ring, a water outlet, a mechanical seal, a centrifugal impeller, a pump body, a wear-resistant rubber sleeve, a spiral blade and a water inlet and is characterized in that the spiral blade is connected onto the pump shaft at the water inlet of the pump body; the centrifugal impeller is mounted on the pump shaft below the water outlet; the wear resistant rubber sleeve is mounted in the pump body on the outer side of the spiral blade; the outer side of the spiral blade is in contact with the wear-resistant rubber sleeve so as to form a sealed cavity on the inner side of the pump body; the diameter of the spiral blade is 10-20 cm; and the diameter of the centrifugal impeller is 30-50 cm. The spiral centrifugal pump has the benefits as follows: the water pump has a low requirement for water quality, is small in size, high in efficiency, smooth in running, low in noise, large in flow, high in lift and wide in application range, reduces the power cost, keeps constant in a whole running period and has great economic and social benefits.
Description
Technical field
The invention belongs to pumps design technical field, be specifically related to a kind of helico-centrifugal pump can carried impurity slurries and extract current.
Background technique
At present, the various water pumps that China produces are all based on centrifugal, and during pump work, because liquid stream throws away from axially entering into radial direction, entering, blade place runner is narrow and flow to the sudden turn of events, and pressure becomes malleation from negative pressure rapidly.Especially multiple-blade centrifugal pump, very easily hook.Blocking, impact normally works.The sudden change flowed to and the urgency of pressure increase, and cause current in pump unstable, and greatly, therefore, the impact of liquid stream in pump, consumes a large amount of energy for blade and liquid stream relative velocity, can not realize harmless conveying.Adding centrifugal impurities pump adopts each cross-sectional area of annular delivery chamber equal, and flow velocity is not etc. everywhere, causes part hydraulic loss yet, causes the efficiency of pump to reduce, cause the waste of power.
Summary of the invention
The present invention overcomes the deficiencies in the prior art part, and provide a kind of energy-efficient, volume is little, and run balance, passing ability is good, strong adaptability, and water flow is large, and lift is high, the helico-centrifugal pump that utilization efficiency is high.
The object of the present invention is achieved like this: helico-centrifugal pump is by spiral " and " centrifugal " two kinds of principle designs structure member composition pump overall, it comprises motor, pump shaft; water retaining ring, water outlet, mechanical close; centrifugal impeller; the pump housing, abrasive rubber cover, helical blade; water intake form; it is characterized in that being connected with helical blade on the pump shaft of pump housing water inlet, the pump shaft below water outlet is equipped with centrifugal impeller, and the pump body outside helical blade is equipped with abrasive rubber cover.
Object of the present invention can also realize like this: overlap with abrasive rubber outside helical blade and contact, make to form closed cavity inside the pump housing, and the diameter of helical blade is 10-20cm, and the diameter of centrifugal impeller is 30-50cm.
Like this, helical blade and centrifugal impeller are on same pump shaft, and spiral and centrifugal two kinds of forms combine together.Helico-centrifugal pump operationally, helical flow path is formed inside the helical blade of inlet end and the pump housing, liquid stream is forced advance in pump and liquid stream that spiral flow channel transports by the centrifugal impeller of water outlet end is forced to discharge from water outlet, therefore, when discharging and carrying high concentration medium, also there is unique positive feed effect and smooth conveying characteristic.
The invention has the beneficial effects as follows that water pump is not tight to water quality requirement, volume is little, and efficiency is high, operates steadily, and noise is low, and flow is large.Lift is high, saves power cost, and all keeps constant during whole service, 2.Applied widely, there is huge economic and social benefit.
Accompanying drawing explanation
Fig. 1 is the overall construction drawing of helico-centrifugal pump
Embodiment
In accompanying drawing, each part numbers is as follows:
1, motor 2, pump shaft 3, water retaining ring 4, mechanical seal 5, water outlet 6, the pump housing 7, centrifugal impeller 8, abrasive rubber cover 9, helical blade 10, water intake
Connect motor (1), pump shaft (2) rotates, liquid at high speed rotation is brought in the pump housing (6) from water intake by helical blade (9) by liquid, again by the centrifugal action of centrifugal impeller (8), liquid is discharged by water outlet (5), so circulates.
Since the present invention tries out successfully, to operate steadily, noise is low, and flow is large, and lift is high, applied widely, has won the accreditation of user etc. feature, promotes wide market, can bring huge economic and social benefit.
