Specific embodiment
The technical scheme in the embodiments of the invention will be clearly and completely described below, it is clear that described implementation
Example is only a part of the embodiments of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, this field is common
Technical staff's all other embodiment obtained without making creative work belongs to the model that the present invention protects
It encloses.
As depicted in figs. 1 and 2, the embodiment of the present invention includes:
A kind of anhydrous self-priming distinguishes the super-silent intelligent water pump of water flow, including the pump housing 1, motor 3, impeller 4, shock bracket 5
And the rear end of flow guiding disc 2 is arranged in pedestal 6, the motor 3, the impeller 4 is arranged between flow guiding disc 2 and motor 3,
The shock bracket 5 is arranged between the pump housing 1 and pedestal 6.In the present embodiment, it is provided with flow guiding disc 2 on the pump housing 1,
The pump housing 1 and flow guiding disc 2 uses integral structure, conventional pump body design flow guiding disc and the pump housing different from conventional pump body design
Then separately design reassembles waste of time, and fixed do not take pains is spinned, and loses performance, sets in the present embodiment middle pump body
In respect of flow guiding disc, flow guiding disc is integral with pump body design, and assembly is simple, and performance is stablized.
Wherein, be provided with water inlet 11, water outlet 12, water filling plug 13 and pull ring 14 on the pump housing 1, it is described into
The mouth of a river 11 and water outlet 12 are separately positioned on the left and right sides of the pump housing 1, and the water filling plug 13 and pull ring 14 are arranged at
The upper end of the pump housing 1.
Conventional self priming pump must be equipped with ejector to meet self-priming before drawing water every time in pump housing topped up with water and the pump housing
Condition, in order to overcome these defects, the present invention solves this problem on flow-guiding structure, as shown in figure 3, the flow guiding disc
2 use leakproofness single outlet structure, are provided with flow guiding disc water outlet 21, flow guiding disc water inlet 22 on the flow guiding disc 2 and lead
Discharge orifice 23, in 2 outside of flow guiding disc, the setting of deflector hole 23 is in flow guiding disc water inlet 22 and leads for the setting of flow guiding disc water outlet 21
Between flow table water outlet 21.Wherein, the diameter of the deflector hole 23 is 1-50mm.When work impeller 4 under high speed rotation into
Vacuum state is formed at mouthful, since flow guiding disc 2 belongs to leakproofness single outlet structure, the entrance of deflector hole 23 and impeller 4 at this time
An open circuit circulation is formed, drives airflow circulating flowing, the entrance negative pressure of impeller 4 is increasing, and water can pass through atmosphere at this time
It is inhaled into flow guiding disc water inlet 22 under pressure effect and is entering the pump housing 1, lower discharge pump is then acted on by the high speed centrifugation of impeller 4
Body 1.
The key factor for forming self-priming condition is high-revolving impeller, rubs due to being chronically under high revolving speed, mechanical
Sealing can generate heat rapidly, if quickly by high temperature melting, sealing will fail for rubber or plastics without suitable radiating condition,
In order to solve this problem, the present embodiment is as shown in figure 4, open up the conduction hole that a diameter is 1-30mm in 4 entrance of impeller
41, using the principle of 4 entrance negative pressure of impeller, the Shi Shuihui that works is inhaled into conduction hole, while cold under the action of impeller 4 rotates
But water can be constantly recycled in mechanical seal, and mechanical seal just obtains the heat dissipation of recirculated water.
As shown in figure 5, the shock bracket 5 uses wild goose type shock bracket, installation is provided in the shock bracket 5
Hole 51.Conventional water pump will form very big noise due to the vibration of motor itself and water flow at work, and water pump is made in high amplitude
It can be loosened with lower screw, entirety can be displaced, motor failure after a period of time, in order to solve this problem present invention combination wild goose limb
The balance and ductility of body solves this problem.
Further, the super-silent intelligent water pump further includes the soft materials and parts silencing means 7 of elasticity, the soft material of elasticity
Part silencing means 7 is arranged between shock bracket 5 and the pump housing 1.Wherein, the soft materials and parts silencing means 7 of the described elasticity and motor 3 it
Between be equipped with gap, clearance distance 0-50mm.Motor 3 shakes at work can pass to the pump housing 1 and shock bracket 5, elastic at this time
Soft materials and parts silencing means 7 can absorb vibration, and shock bracket 5 and ground face contact extension, which are spread out, increases contact area to open noise reduction
The purpose of damping.
In the present embodiment, the motor 3 uses brshless DC motor.Conventional water pump motor, which uses, brush series excited machine,
Self-priming performance is improved using its high revolving speed, but has the brush series excited machine service life there was only 200 hours, noise can achieve when work
60 decibels, for a long time using that can make one irritated under high noise environments, in order to solve this problem, the present invention utilizes brushless dc
Machine is in conjunction with water pump, and service life 2000 hours or more, mute state is in when work, achieved the purpose that it is efficient super-silent,
And intelligent brushless motor has the function of blocking rotation, preventing idle load, burn-out-proof machine, super-silent.
Wherein, the motor 3 includes front motor cover 31, motor casing 32, stator (figure not depending on), rotor (figure does not regard), electricity
Machine rear cover 33, control panel 34 and PCB housing 35, the front motor cover 31 are connect by screw with the pump housing 1, the stator with
Rotor is arranged in motor casing 32, and the motor casing 32 is connect by screw with front motor cover 31, and the control panel 34 is set
It sets on motor rear cover 33, the heater element on the control panel 34 is fitted and connected with motor rear cover 33, after the motor
Lid 33 is connect by screw with motor casing 32, and the PCB housing 35 is connect by screw with motor rear cover 33.
Among the above, the front motor cover 31 and 33 material of motor rear cover are all made of cast iron or aluminium alloy or kirsite or copper
Alloy；32 material of motor casing is using cast iron or aluminium alloy or kirsite.
It is of the invention compared with prior art, have the advantages that
1, the pump housing and flow guiding disc use integral structure, and the pump body design with guide functions solves the complexity assembled in the past
