Background technique
The typical belt drive-type water pump structure of available engine, as shown in Figure 1, water pump pulley 11 and pump shaft 12 are same
Axis setting, pump shaft 12 are mounted in water pump body 13.Under the driving of water pump pulley 11, pump shaft 12 is rotated together, band rotating vane
16 rotation of wheel is finally pumped out from water so that cooling water is inhaled into from pump intake 17, and produces high pressure in water pump high pressure chest 14
The mouth of a river 15 is discharged.
Since the engine water pump belt service life is uncontrollable, damage is difficult to predict.Once the decline of water-pump belts tensile force or damage
The strength of bad or fracture, driving water pump pulley 11 just declines, and the just decline (or being zero) of 11 speed of water-pump belts rotation causes water
The ability decline that pump pumps, in turn results in coolant rate decline (or being zero), causes engine therefore can cool down bad
Failure.
Summary of the invention
In view of the above-mentioned problems, the present invention provides a kind of simple and reasonable engine water pump, the engine water pump is not

Force snesor, the pressure of real-time monitoring water pump high pressure chest have corresponding relationship with pressure by pump capacity, can find water in time
Pump declines and takes necessary measure, avoids causing engine that cooling undesirable failure occurs since coolant rate declines.
Technical solution provided by the present invention is as follows:
The present invention provides a kind of engine water pumps, comprising: water pump body, water pump pulley and pump shaft are coaxially disposed, water
Pump shaft is mounted in water pump shell, and under the driving of water pump pulley, pump shaft band rotary impeller is rotated, and water pump is formed in water pump shell
High pressure chest；Force samples hole is offered on the corresponding water pump shell of water pump high pressure chest；And pressure sensor, it is directly installed on
It is connect on force samples hole or by connecting pipe with force samples hole, to be adopted to the coolant pressure in water pump high pressure chest
Sample.
Preferably, in above-mentioned technical proposal, force samples hole be arranged in the corresponding water pump shell of water pump high pressure chest top, under
Side or side.
Preferably, in above-mentioned technical proposal, pressure sensor is piezoelectric transducer.
Compared with prior art, the invention has the following beneficial effects: the engine water pumps not change water pump original
On the basis of primary structure and water pumping function, the pressure sensor of monitoring water-aspirator pressure is added at water pump high pressure chest, is supervised in real time
The pressure for surveying water pump high pressure chest, has corresponding relationship with pressure by pump capacity, can find that water pump declines and take must in time
The measure wanted avoids causing engine that cooling undesirable failure occurs since coolant rate declines.

Specific embodiment
With reference to the accompanying drawing, specific embodiments of the present invention will be described in detail, it is to be understood that guarantor of the invention
Shield range is not limited by the specific implementation.
As shown in Figures 2 to 4, the specific structure of the engine water pump of specific embodiment includes: water pump according to the present invention
Ontology and the pressure sensor 28 that monitoring water-aspirator pressure is added at the water pump high pressure chest of the water pump body, wherein water pump sheet
Body does not change the primary structure of original water pump and pumps function.It offers at the water pump high pressure chest of the water pump body and is passed for pressure
The force samples hole of 28 real-time monitoring water pump high pressure cavity pressure of sensor, in this way, being closed using pump capacity is corresponding with its pressure
System can find water pump decline in time and take necessary measure, avoid causing engine to be sent out since coolant rate declines
The undesirable failure of raw food.
In the cylinder body of automobile engine, there is the water channel of a plurality of Cooling Water circulation, with the radiator for being placed in automobile front
(being commonly called as water tank) is connected by water pipe, constitutes a big water circulation system, in the cooling liquid inlet position of engine, dress
There is a water pump body, driven by belt, the hot water in engine cylinder body water channel is pumped out, cold water is pumped into.In water pump
Side do not opened when automobile just starts when (cold vehicle) there are one thermostat, make cooling water without water tank, only starting
Circulation (being commonly called as partial circulating) turns on when the temperature of engine reaches 80 degree or more in machine, and in-engine hot water is pumped
Enter water tank, cold wind when automobile front driving blows over water tank, takes away heat.Wherein, the water pump pulley 21 and pump shaft of water pump body
22 coaxial arrangements, pump shaft 22 are mounted in water pump shell 23.Under the driving of water pump pulley 21, pump shaft 22 is rotated together, band
Rotary impeller 26 rotates, so that cooling water is inhaled into from pump intake 27, and produces high pressure in water pump high pressure chest 24, finally from
Pump outlet 25 is discharged, and is sent to engine.
Force samples hole 29 is offered on the corresponding water pump shell 23 of water pump high pressure chest 24, it is right for pressure sensor 28
Coolant pressure in water pump high pressure chest 24 is sampled, and then 24 pressure of real-time monitoring water pump high pressure chest.Force samples hole 29
The top, lower section or side (as shown in Figures 2 to 4) of the corresponding water pump shell 23 of water pump high pressure chest 24 are set.
Pressure sensor 28 is a kind of sensor the most commonly used in industrial practice.Generally usual pressure sensor is defeated
It is out analog signal, analog signal refers to that information parameter shows as continuous signal in given range.Or it is continuous at one section
In time interval, the characteristic quantity of representative information can be rendered as the signal of any number in any moment.And we usually make
Pressure sensor is mainly to be fabricated using piezoelectric effect, and such sensor is also referred to as piezoelectric transducer.
Pressure sensor 28 is directly installed on force samples hole 29 or is connected by connecting pipe 30 and force samples hole 29
It connects, to be sampled to the coolant pressure in water pump high pressure chest 24, and then 24 pressure of real-time monitoring water pump high pressure chest.Due to
Pump capacity is with the pressure of water pump high pressure chest 24 in relation to corresponding relationship, it is known that the pressure of water pump high pressure chest 24 is just relevant to
It is aware of the flow of water pump.When tension declines or damages, the strength of driving water pump pulley 21 just declines water-pump belts,
Pump shaft 22, wheel speed decline, the pressure of water pump high pressure chest 24, pump capacity will decline.Pass through monitoring high pressure chest 24
Pressure understands the flow of water pump, when the pressure of water pump high pressure chest 24 declines (flow decline), takes timely measure and avoids flowing
Amount deficiency causes engine overheat to break down.
To sum up, the engine water pump is not on the basis of changing the original primary structure of water pump and pumping function, in water pump
Added at high pressure chest monitoring water-aspirator pressure pressure sensor, the pressure of real-time monitoring water pump high pressure chest, by pump capacity with
Pressure has corresponding relationship, can find in time water pump decline and take necessary measure, avoid due to coolant rate decline and
Cause engine that cooling undesirable failure occurs.
The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this
The principle of invention, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these changes
Change and improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and its
