Abstract
The utility model relates to a household miniature motor-operated water pump. A single-stage horizontal type vortex pump with a closed impeller and open type flow channel whose two side edges are rectangular cross sections is adopted, a single phase motor is used for driving, the blade wheel and the shaft is in a floating matching, and the diameter of the impeller is 45 millimeters. The utility model has small size and light weight, the power of the motor is only 40W, the delivery lift can reach 0-9 meters, the corresponding flow quantity is 22-0L, and the maximal suction lift can reach more than 7 meters. During work process, the utility model has low noise, no leakage, and no clamping, which can be used for both cold water and hot water (0-80 DEG celsius), being suitable for supplying water from high position, heating through hot water circulation, and establishing 'undeveloped tap water' for peasant households.
Description
The utility model relates to a kind of water pump.
When urban family used tap water now, the resident of high-rise building tends to run into because of the not enough problem of not using water of hydraulic pressure, and was troubling; And in vast rural area, most of family all uses well water, very inconvenience.In addition, water heater has begun to enter urban family, only does bathing usefulness at present usually, if can make hot water form circulation in the room, for family's heating, then brings bigger facility to people.This all problem all needs a kind of micro pump of economy to solve.And do not have a kind of suitable micro pump on the market now, and existing small pump or power is big (more than 120 watts), and volume, weight are also big; Flow, lift are too little, are not suitable for most of families and use.
The purpose of this utility model is to provide a kind of micro pump that most of families use that is fit to, and it just can reach required flow and the lift of family's use under less power and volume, weight.
Solution of the present utility model is: the single-stage horizontal peripheral pump that adopts rectangular cross-section, double shrouded wheel bilateral limit open type runner, drive with single-phase differential motor, cooperate for floating between impeller and the axle, equalizing orifice on the impeller is the keyway formula, the oil sealing of external sealed form is adopted in the sealing of axle, one annular triangular groove is arranged so that " 0 " shape seal ring to be installed between housing and the protecgulum, impeller diameter is 45 millimeters, the impeller width is 7 millimeters, the number of blade is 36, runner shaft section area is 161 square millimeters, and axial and radial clearance is 0.1 millimeter, and power of motor is 40 watts.
Accompanying drawing 1. electric household micro pump structural representations.
Accompanying drawing 2. blade wheel structure schematic representation.
The experimental features figure of accompanying drawing 3. electric household micro pumps.
Below in conjunction with an accompanying drawing and an embodiment the utility model is described in detail, but actual product is not limited to this embodiment.
Use required tap water flow and range of lift according to common family, selected design point flow of the present utility model is 8 liters/minute, and lift is 6.5 meters; Three characteristics of the middle term motor is not suitable for family expenses, and the utility model adopts single phase motor to drive pump impeller work, and motor speed is 2800 rev/mins; By such flow, lift and rotating speed, getting specific speed is 30 rev/mins, and it is little, in light weight also will to satisfy volume simultaneously, thereby adopts peripheral pump to realize task of the present utility model.
Structural feature according to peripheral pump, the utility model has adopted the single-stage horizontal peripheral pump (seeing accompanying drawing 1) of rectangular cross-section, double shrouded wheel bilateral limit open type runner, the diameter of impeller (6) is 45 millimeters, the impeller width is 7 millimeters, the number of blade is 36, process with milling cutter, the shaft section area of runner (13) is 161 square millimeters, and axial and radial clearance is 0.1 millimeter.Because of the pump housing is little, for guaranteeing the gap and be convenient to assembling, adopt unsteady the cooperation between impeller (6) and the axle (8), connect with key (3); Under the very little situation of impeller radial dimension, for guaranteeing the appropriate width of impeller seals band, equalizing orifice on the impeller (15) is made keyway formula (seeing accompanying drawing 2), being equalizing orifice opens inner radius at impeller with the form of keyway, gets keyway (14) in an embodiment and becomes three-flute uniform with two equalizing orifices (15); The oil sealing (7) of external sealed form is adopted in the sealing of axle, be the outer end that oil sealing is placed in peripheral pump housing (12), neither influence unsteady cooperation the between impeller and the axle, guaranteed the appropriate width of impeller seals band again, and with low cost, adopt single oil sealing in an embodiment; For guaranteeing assembly precision, processing one annular triangular groove (1) is used for installing " 0 " shape seal ring between the housing (12) of peripheral pump and protecgulum (2), rather than seal ring directly filled up between the end face of housing and protecgulum, annular in an embodiment triangular groove is that rounded corner forms in the housing front end, and seal ring is then used circular cross-section.The motor (9) that drives peripheral pump work be single-phase differential motor, learns that according to calculating such as the flow of pump, efficient power of motor is 40 watts, selects 40 watts of single-phase capacitance differential motors of Nanjing Micromotor Factory's production in an embodiment for use, works well; Connect by link (10) and fastening piece (5) between motor and the peripheral pump, link can be processed separately to match with commercially available finished product motor and link to each other, also can directly motor housing be processed into required form, annular boss on it (11) is in order to locate to peripheral pump, fastening piece (5) can adopt three screws to be uniformly distributed along the circumference, and housing is fixed on the link (10) with protecgulum.The caliber of importing and exporting water pipe (4) is equally big or small, and desirable 12 millimeters, the cut water width is then got 10 millimeters.
Embodiment of the present utility model is drawn pump characteristics figure (seeing accompanying drawing 3) through experiment, as can be seen from the figure, the flow of pump, lift all reach designing requirement, and lift of pump can be 0～9 meter, corresponding flow is 22～0 liters/minute, and the maximum of pump suction journey can reach more than 7 meters.Overall weight of the present utility model is no more than 2.5 kilograms, external diameter is not more than 80 millimeters, length is not more than 160 millimeters, cost is not higher than 120 yuan, and noise is low in the working procedure, does not have to leak, not stuck, hot and cold water (0～80 degree centigrade) all can use, and is desirable piston type domestic water pump, as high-order supply water, hot water circuit and for peasant household's foundation " native tap water " etc. all very suitable.
