Abstract
The utility model discloses a booster water pump which comprises a pump body 3 provided with an inlet 22 and an outlet 23, wherein a rotating shaft 18 and an impeller 5 fixedly connected with the rotating shaft 18 are arranged in the pump body 3. The utility model is characterized in that one side of the pump body 3 is fixedly connected with a shell provided with an inlet 10 and an outlet 6; an impeller 14 fixedly connected with the rotating shaft 18 is arranged in the shell. The utility model has the advantage that the booster water pump can utilize return water potential energy to save energy for reducing the design lifting distance of the water pump or decreasing the motor power of a circulation water pump.
Description
The utility model relates to a kind of water pump, especially a kind of booster water pump.
Present water pump power all derives from motor, and the potential energy of backwater wastes in the circulatory system.
The purpose of this utility model provides a kind of backwater potential energy that can utilize and saves the water pump that the energy can reduce rated lift or reduce circulation-water pump electric machine power.
Technical solution of the present utility model is: a kind of booster water pump, comprise the pump housing 3 that is provided with inlet 22 and outlet 23, rotating shaft 18 and the impeller 5 affixed with rotating shaft 18 are housed in the pump housing 3, it is characterized in that: a side of the pump housing 3 is connected with and is provided with inlet 10 and outlet 6 housing, and the impeller 14 affixed with rotating shaft 18 is housed in the housing.
Described housing is a scroll casing shape, and inner chamber is provided with baffle plate.
Blade on the described impeller 14 is a lateral bending shape.
The utility model compared with prior art has the advantage that can utilize the backwater potential energy saving energy can reduce the water pump rated lift or reduce circulation-water pump electric machine power.
Below in conjunction with accompanying drawing the utility model embodiment is further described:
Fig. 1 is the utility model embodiment's a main cross-sectional schematic;
Fig. 2 is that the utility model embodiment axle is surveyed schematic representation.
As Fig. 1, shown in 2, the pump housing is an ironcasting, pump housing protecgulum 3 is provided with inlet 22 and outlet 23, and stud with seal ring 2, rotating shaft 18 is housed in the pump housing, impeller 5 is housed in the rotating shaft 18, rotating shaft 18 is used key connecting with impeller 5, it is fixing to add lock washer 4 with nut 1, one side of pump housing protecgulum 3 and potential energy engine housing Bolt Connection, the potential energy engine housing is provided with water inlet 10 and water outlet 6, and housing is that the scroll casing shape ironcasting is to be formed by slider 12 and bonnet 16 usefulness bolted on connections, and inner chamber is provided with into hydroecium baffle plate 21 and water-supplying chamber's baffle plate 20, impeller 14 with rotating shaft 18 key joints is housed in the housing, blade on the impeller 14 is a lateral bending shape, and axle sleeve 7 is equipped with in 18 of bonnet 16 and rotating shafts, packing ring 8, filler 9 and Gland 11, bearing 17 is equipped with in 18 of pump housing back poppet 19 and rotating shafts.
Its working procedure is: the system's backwater that has certain pressure is entered into hydroecium 15 by potential energy machine water inlet 10, going into hydroecium baffle plate 21 forces the lateral bending blade on the water slug impeller 14 to make impeller 14 rotations drive rotating shaft 18 rotations, thereby drive water pump vane 5 work, system's backwater enters water-supplying chamber 13 along water-supplying chamber's baffle plate 20 move a week in scroll casing shape potential energy casing after, is got back in the system by water outlet 6.Because system's backwater work done, increase actual input power, thereby under the constant situation of input power, improved the lift of water pump, that is to say the motor that has adopted this booster water pump can select lower-wattage.
