Abstract
The utility model provides a pipe booster pump, which belongs to a technology field of pumps. The utility model solves the problem that service life of products is short, which is led because prior pipe booster pump does not have special cooling device to reduce temperature of a motor. The pipe booster pump comprises a shell, a motor, a pump body and a blade wheel, wherein the motor is positioned in the shell, the pump body is fixedly connected with the motor, the blade wheel is positioned in the pump body, one end of a rotation shaft of the motor is fixedly connected with the blade wheel, the other end of the rotation shaft of the motor is fixedly connected with a wind wheel, a ventilation gap is arranged between the shell and the motor, an air inlet is opened on the shell of the side of the wind wheel, and an air outlet is arranged on the shell which is close to the pump body. The wind wheel rotates along with rotation of the motor in the pipe booster pump. The utility model uses air flow, thereby greatly improving radiating effect of the motor, reducing temperature of the booster pump, prolonging service life of the booster pump, and having high practical value.
Description
Technical field
The utility model belongs to the pump technical field, particularly a kind of pipe pressurizing pump.
Background technique
The pipe pressurizing pump is when work, and motor can generate heat, and makes the whole pump housing have higher temperature.This will influence motor properties, shorten the working life of suction booster.But, in existing pipe pressurizing pump, do not make the cooling unit of motor cooling in the pump specially.
Summary of the invention
The purpose of this utility model is at the problems referred to above, and a kind of structure improved novel pipe pressurizing pump is provided, and makes it have the characteristics of rational in infrastructure, good heat dissipation effect, long service life.
For achieving the above object, the utility model has adopted following technical proposal: this pipe pressurizing pump comprises casing, motor, the pump housing and impeller, motor is positioned at casing, the pump housing and motor are connected, and impeller is positioned at the pump housing, and rotating shaft one end and the impeller of motor are connected, the other end of the machine shaft fan blade that is being connected, leave ventilation gap between casing and the motor, on the casing of fan blade sidepiece, have intake grill, on casing, be provided with exhaust outlet near pump housing place.
In this pipe pressurizing pump, fan blade will rotate along with the rotation of motor.Particularly, when suction booster turned round, fan blade rotated, and drove air and was entered by the intake grill of casing, behind the ventilation gap between casing and the motor, was discharged by the exhaust outlet of casing.Like this, utilize air flows, improved radiation effect of motor greatly, reduced the temperature of suction booster, thereby prolong the working life of suction booster.
Compared with prior art, this pipe pressurizing pump mainly is to set up a fan blade on common pipe pressurizing pump foundation, and its product cost increases few, but can prolong the working life of product greatly, so have higher utility.
Description of drawings
Fig. 1 is the profile schematic representation of the pipe pressurizing pump that provides of the utility model.
Fig. 2 is the sectional view of the pipe pressurizing pump that provides of the utility model.
Among the figure, 1, casing; 2, motor; 3, the pump housing; 4, impeller; 5, rotating shaft; 6, fan blade; 7, intake grill; 71, intake opening; 8, exhaust outlet; 81, exhaust vent; 9, ventilation gap.
Embodiment
As depicted in figs. 1 and 2, the suction booster of present embodiment is a kind of high pressure peripheral pump.It comprises parts such as casing 1, motor 2, the pump housing 3, impeller 4 and fan blade 6.It is that material is made that casing 1 adopts stainless steel.It is material that the pump housing 3 and impeller 4 all adopt copper.Impeller 4 and fan blade 6 are fixed on rotating shaft 5 two ends of motor 2 respectively.Obviously, when suction booster is worked, fan blade 6 will rotate simultaneously with impeller 4.
As shown in the figure, on the casing 1 of fan blade 6 sidepieces, intake grill 7 is arranged.In the present embodiment, intake grill 7 is made up of several intake openings 71.Under the drive of fan blade 6, casing 1 outer air will be entered in the casing 1 by each intake opening 71.
On casing 1, be provided with exhaust outlet 8 near the pump housing 3 places.In the present embodiment, exhaust outlet 8 is made up of several exhaust vents 81.Simultaneously, exhaust vent 81 is uniformly distributed in the surface of casing 1.
Be tool ventilation gap 9 at regular intervals between casing 1 and motor 2, pass through for air.
When the supercharging pump housing turned round, the air that is entered by intake grill 7 by the ventilation gap 9 between casing 1 and the motor 2, was discharged from exhaust outlet 8 under the drive of fan blade 6 at last.By this process, accelerated the heat dissipation rate of motor 2, make whole suction booster keep lower operating temperature, help prolonging the working life of product.
