Because the engine water pump belt life-span is uncontrollable, damage and be difficult to prediction.Water-pump belts is once tension force declines or damages or fracture, the strength of water pump pulley 11 is driven just to decline, water pump pulley turns 11 speed and just declines (or being zero), the ability of water pump pump water is caused to decline, and then cause coolant rate to decline (or being zero), cause motor therefore can occur to cool bad fault.
The information being disclosed in this background technique part is only intended to increase the understanding to general background of the present utility model, and should not be regarded as admitting or imply in any form that this information structure has been prior art that persons skilled in the art are known.
Model utility content
The purpose of this utility model is to provide a kind of simple and reasonable engine water pump, this engine water pump is on the basis not changing the original main structure of water pump and pump water function, the pressure transducer of monitoring water-aspirator pressure is set up at water pump hyperbaric chamber place, the pressure of Real-Time Monitoring water pump hyperbaric chamber, corresponding relation is had by pump capacity and pressure, can decline and take necessary measure by Timeliness coverage water pump, avoiding causing because coolant rate declines motor that the bad fault of cooling occurs.
For achieving the above object, the utility model provides engine water pump, comprising: water pump body, its water pump pulley and water pump spindle are coaxially arranged, and water pump spindle is arranged in water pump shell, under the driving of water pump pulley, water pump spindle band rotary impeller rotates, and forms water pump hyperbaric chamber in water pump shell; The water pump shell that water pump hyperbaric chamber is corresponding offers force samples hole; And pressure transducer, it is directly installed on force samples hole or by PRESSURE PIPE and is connected with force samples hole, samples to the coolant pressure in water pump hyperbaric chamber.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but is to be understood that protection domain of the present utility model not by the restriction of embodiment.
Clearly represent unless otherwise other, otherwise in whole specification and claims, term " comprise " or its conversion as " comprising " or " including " etc. by be understood to include the element of stating or constituent element, and do not get rid of other element or other constituent element.
As shown in Figures 2 to 4, concrete structure according to the engine water pump of the utility model embodiment comprises: water pump body and the water pump hyperbaric chamber place at this water pump body set up the pressure transducer 28 of monitoring water-aspirator pressure, wherein, water pump body does not change main structure and the pump water function of original water pump.The water pump hyperbaric chamber place of this water pump body offers the force samples hole for pressure transducer 28 Real-Time Monitoring water pump hyperbaric chamber pressure, like this, utilize the corresponding relation of pump capacity and its pressure, decline with regard to energy Timeliness coverage water pump and take necessary measure, avoiding causing because coolant rate declines motor to occur to cool bad fault.
In the cylinder body of motor car engine, there is the water channel of many Cooling Water circulations, be connected by water pipe with the radiator (being commonly called as water tank) being placed in automotive front, form a large water circulation system, in the cooling liquid inlet position of motor, a water pump body is housed, is driven by belt, hot water in engine cylinder-body water channel is pumped, cold water is pumped into.A thermostat is also had on the side of water pump, when automobile just starts time (cold car), do not open, make cooling water without water tank, only motor Inner eycle (being commonly called as short circle), when the temperature of motor reaches more than 80 degree, just open, in-engine hot water is pumped to water tank, and cold wind during automobile front driving blows over water tank, takes away heat.Wherein, water pump pulley 21 and the water pump spindle 22 of water pump body are coaxially arranged, and water pump spindle 22 is arranged in water pump shell 23.Under water pump pulley 21 drives, water pump spindle 22 rotates together, and band rotary impeller 26 rotates, and cooling water is inhaled into from pump intake 27, and produces high pressure at water pump hyperbaric chamber 24, finally discharge from pump outlet 25, deliver to motor.
The water pump shell 23 of water pump hyperbaric chamber 24 correspondence offers force samples hole 29, samples for the coolant pressure in pressure transducer 28 pairs of water pump hyperbaric chambers 24, and then Real-Time Monitoring water pump hyperbaric chamber 24 pressure.Force samples hole 29 is arranged on the top of the water pump shell 23 of water pump hyperbaric chamber 24 correspondence, below or side (as shown in Figures 2 to 4).
Pressure transducer 28 is a kind of sensors the most conventional in industrial practice.The output of general usual pressure sensor is analogue signal, and analogue signal refers to that information parameter shows as continuous print signal in given range.Or within one period of continuous print time lag, the characteristic quantity of its representative information can at the signal being rendered as arbitrarily any number instantaneously.And our normally used pressure transducer mainly utilizes piezoelectric effect manufacture, such sensor is also referred to as piezoelectric transducer.
Pressure transducer 28 is directly installed on force samples hole 29 or by PRESSURE PIPE 30 and is connected with force samples hole 29, samples to the coolant pressure in water pump hyperbaric chamber 24, and then Real-Time Monitoring water pump hyperbaric chamber 24 pressure.Because the pressure of pump capacity and water pump hyperbaric chamber 24 is about corresponding relation, the pressure being aware of water pump hyperbaric chamber 24 is just relevant to the flow being aware of water pump.Water-pump belts declines once tension force or damages, and drive the strength of water pump pulley 21 just to decline, water pump spindle 22, wheel speed decline, and pressure, the pump capacity of water pump hyperbaric chamber 24 will decline.Understood the flow of water pump by the pressure of monitoring hyperbaric chamber 24, when pressure drop (the flow decline) of water pump hyperbaric chamber 24, take measures in time to avoid underfed to cause engine overheat to break down.
To sum up, this engine water pump is on the basis not changing the original main structure of water pump and pump water function, the pressure transducer of monitoring water-aspirator pressure is set up at water pump hyperbaric chamber place, the pressure of Real-Time Monitoring water pump hyperbaric chamber, corresponding relation is had by pump capacity and pressure, can decline and take necessary measure by Timeliness coverage water pump, avoiding causing because coolant rate declines motor that the bad fault of cooling occurs.
The aforementioned description to concrete exemplary of the present utility model is to illustrate and the object of illustration.These descriptions not want the utility model to be defined as disclosed precise forms, and obviously, according to above-mentioned instruction, can much change and change.The object selected exemplary embodiment and describe is to explain certain principles of the present utility model and practical application thereof, thus those skilled in the art can be realized and utilize various different exemplary of the present utility model and various different selection and change.Scope of the present utility model is intended to limited by claims and equivalents thereof.
