Abstract

The utility model discloses an energy-saving efficient water supply booster pump, which comprises a motor (14), a driving wheel, a speed reducer (12) and a pump body, wherein the pump body comprises a pump casing (6), a water outlet pipe (2) and a water inlet pipe (9) which are respectively communicated and connected with two ends of the pump casing, rotating shafts (7) movably supported at two ends of the pump casing, rollers (5) arranged on the rotating shafts, and helical blades (4) arranged on the rollers at intervals, wherein the water outlet pipe is conical, the motor is connected with the speed reducer through transmission acceleration, and the speed reducer is connected with the rotating shafts through transmission acceleration. In the utility model, the rotating shafts drive the helical blades to continuously circulate and rotate; due to the action of the helical blades, quick flowing water after being pressed in the quick water inlet pipe is input to the water outlet pipe, so that the water outlet pipe can generate high-pressure water. The utility model has the advantages of compact structure, convenience in manufacturing, strong durability and electrical energy economization, is suitable for the use of a water supply system at a higher-end and a low water-head hydropower, and is mainly suitable for the use of small-and-medium sized hydroelectric generators.

Description

Efficient energy-saving water supply suction booster

Technical field

The utility model relates to water pump, especially relates to a kind of efficient energy-saving water supply suction booster.

Background technique

Water pump is the most frequently used mechanical driver unit of water system, utilizes water pump can realize supplying water at a distance and to high-end place, and water supply distance or water supply are highly high, and the electric power that its water pump consumed is big.At present, various water pumps are because structural limitations, identical down in water flow, lift whenever double the needed electric power of water pump must double above, generally speaking, to lift is that 50 meters high-end places supply water, pump motor power is wanted more than the 35KW at least, is that 100 meters high-end places supply water to lift, and the electric power that water pump consumed is at least more than the 75KW, therefore, existing water pump is big to the electric power that the water supply of high-end place is consumed.

The model utility content

At in the above-mentioned existing technology to the excessive problem of high-end place's water supply pump electrical consumption power, the utility model provides a kind of water supply lift height, but water pump consumes the lower efficient energy-saving water supply suction booster of power of motor.

The technological scheme that the technical problems to be solved in the utility model is taked is: described efficient energy-saving water supply suction booster comprises motor, drive wheel, retarder and the pump housing, the described pump housing comprises that pump case, described pump case two ends interlink respectively and is connected to outlet pipe with intake pipe, have rotating shaft, rotating shaft one end to link to each other with drive wheel in pump case two ends movable supporting, cylinder is set in rotating shaft, helical blade is set on cylinder at interval, it is conical that described outlet pipe is, motor links to each other with retarder after by the transmission speedup, and retarder links to each other with rotating shaft after by the transmission speedup.

The utility model is owing to adopt two-stage transmission speedup and the input rotating shaft of retarder deceleration back, make rotating shaft produce a power that is lower than motor speed and turns round button greatly, rotating shaft drives the helical blade rotation that constantly circulates, because helical blade effect, water in the intake pipe is input in the outlet pipe after the pressurization fast, make the water generates high pressure of outlet pipe, the motor of a 45KW can make water supply pressure reach 5-10Kg/cm2, the water supply lift reaches 100-150 rice, realizes the purpose of the high-lift water supply of low electric power.The utility model is compact structure, easily manufactured not only, and serviceability is strong, and saving power, and it is applicable to high-end place water system and uses and the low-head hydraulic generating, is applicable to that mainly middle-size and small-size hydroelectric generator uses.
