Abstract
The invention discloses a water pump. The water pump comprises a motor and a water pump body. A cylindrical propeller and a check wedge-shaped bump in the water pump and a water outlet part designed according to a fluid mechanical principle are arranged in streamlines, so that the efficiency can be improved by about 30 percent. Paddles of the cylindrical propeller are arranged in the way that the axial view is overlapped slightly to strengthen the unidirectivity; the arrangement of the check wedge-shaped bump also strengthens the unidirectivity; the water outlet part is designed to a streamline, so that the resistance can be reduced and the efficiency can be improved; and a wedge-shaped groove is formed by one side of the check wedge-shaped bump, one side of the propeller and the wall of the pump body, so that a check effect is achieved, the unidirectivity is strengthened and the efficiency is improved. A rubber piece is arranged on the shaft between the motor and the pump body, so that the pump body is prevented from leaking and splashing to the motor to damage the motor; and a water inlet pipe is provided with a check valve. The water pump is high in efficiency and low in cost, and has a popularization value.
Description
Technical field
The present invention relates to a kind of water pump.
Background technique
In the existing technology, be mostly centrifugal water pump, efficient has only about 60%, causes great waste, we can say that Centrifugal water pump is a mistake.
Summary of the invention
The purpose of this invention is to provide a kind of water pump, comprise motor and water pump body, mainly is the streamlined setting in water part protruding and that design according to fluid mechanics principle with the non-return wedge of cartridge type propeller cavitation in the water pump body; Can raise the efficiency about 30%, the blade of cartridge type propeller cavitation is arranged to axial view to be had overlappingly to strengthen one-way slightly, and protruding setting of non-return wedge also is in order to strengthen one-way; The water part is designed to streamlined, can reduce resistance, raises the efficiency; Protruding propeller cavitation one side of non-return wedge becomes the wedge groove with pump housing wall; Play the non-return effect, strengthen one-way, raise the efficiency.On the axle between the motor and the pump housing, a sheet rubber is set, damages motor on the motor in case the pump housing leaks to splash, water inlet pipe is provided with safety check.This pump efficiency is high, and cost is low, has promotional value.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the structural representation of cartridge type propeller cavitation.
Embodiment
Label among the figure: the axle of the blade 13 cartridge type propeller cavitations of 1 motor, 2 pump housings and motor fixed is provided with 3 splashproof sheet rubber 4 sealing gaskets, 5 motors and protruding 7 valves of water pump spindle 6 non-return wedges 8 water parts streamlined tube 12 cartridge type propeller cavitations that 9 cartridge type propeller cavitations, 10 water inlet safety check, 11 cartridge type propeller cavitations are set
With reference to Fig. 1, Fig. 2, the present invention is a kind of water pump, has 1 motor and pump housing two-part, on the axle between the pump housing and 1 motor 3 splashproof sheet rubbers is set; The damage motor in case the pump housing leaks, the 2nd, the fixed setting of the motor and the pump housing, the 4th, sealing gasket, the axle of 5 motors and water pump; The 6th, the non-return wedge is protruding, can strengthen one-way, 7 valves, the streamline setting of 8 water parts; Can reduce resistance, the 9th, the cartridge type propeller cavitation, the 10th, the water inlet safety check can be arranged to ball-type.The tube of 11 cartridge type propeller cavitations can be raised the efficiency, the blade of 12 cartridge type propeller cavitations, and formula layout in the shape of a spiral, axial view should have overlapping slightly, to strengthen one-way, the axle of 13 cartridge type propeller cavitations.Low-cost high-efficiency of the present invention is worthy to be popularized.
