Description
technical field: the utility model relates to design and the improvement of cooling water pump of combustion engine, is a kind of temp. control flow measuring cooling water pump of combustion engine.
background technique: prior art internal combustion engine optimum temperature is between 76 ℃～86 ℃, on it, cooling waterpump water intake is directly connected to water tank, under certain rotating speed, pump water inlet is much, inflow is exactly much, can not regulate, simultaneously, because water pump pulley size immobilizes, pump rotary speed is also constant under certain operating mode, cause internal-combustion engine every task start organism temperature when too low water pump also as usual operate at full capacity, make a large amount of circulating water between water pump and body, carry out invalid circulation, so both affected body preheat time of 76 ℃～86 ℃ from normal temperature to optimum working temperature, waste energy again.
model utility content: the purpose of this utility model will solve exactly the existing water flow of existing cooling water pump of combustion engine and can not regulate, and causes the engine warming up time long, and the invalid waste problem of the energy, provides a kind of temp. control flow measuring internal combustion engine water pump.
Concrete scheme of the present utility model is: a kind of temp. control flow measuring cooling water pump of combustion engine, it has the pump housing, on the pump housing, be respectively equipped with bearing position, water seal position, suction chamber, pumping chamber, water outlet, bearing position place at the pump housing is equipped with shaft connecting bearing, on shaft connecting bearing, the left end axle journal interference of axle is provided with drive pulley, the inclined to one side middle part axle journal of axle and the place's interference of the water seal position of the pump housing are provided with water seal, the right-hand member axle journal interference of axle is provided with impeller, described impeller is mounted between pump housing suction chamber water outlet and pumping chamber, right side at pump housing pumping chamber is also provided with liner and cover plate, cover plate is provided with water outlet, it is characterized in that: pump housing water inlet has circular cross-section flange, at flanged surface, place is provided with fill hose joint with bolt, heat-operated valve is installed in fill hose joint.
The utility model heat-operated valve is provided with upper bracket, lower support frame, valve, spring, thermostatic element.Wherein thermostatic element is comprised of inductor, rubber pipe, paraffin+copper powder+al powder mixt, little sealing gasket, sealing cover and center-pole, upper bracket is provided with a valve port, lower support frame bottom is provided with spring seat, spring housing is in thermostatic element lower end, a valve is installed in thermostatic element middle part shoulder place interference, it is ￠ 5 apertures that valve is provided with two diameters, when water temperature during lower than 76 ℃ valve close completely, the water that on valve, two apertures provide small flow circulation between water pump and machine are stopped, now water pump consumed power is little, on organism temperature is rapid, grow to 76 ℃, when cooling waterpump temperature is between 76 ℃～86 ℃, induction paraffin is liquefy gradually, volume increases thereupon, rubber pipe is shunk, thereby the center-pole bottom conical surface is produced to upwards thrust.Because the upper end of bar is fixed, therefore center-pole produces downward reaction thrust to rubber pipe and inductor, overcome spring tension valve is opened gradually, valve port water inlet area progressively increases, and water feeding of water pump amount is also progressively strengthened.When in internal combustion (IC) engine airframe, water temperature is elevated to, valve will be opened completely 86 ℃ time, it is maximum that water feeding of water pump amount reaches, water pump runs well completely, now water pump consumed power is maximum, guarantee engine cooling water normal circulation between water pump, body and water tank, internal-combustion engine is stable operation between 76 ℃～86 ℃.
The utility model and existing cooling water pump of combustion engine comparison, by heat-operated valve is installed at pump water inlet place, make water pump change to control uninterrupted according to engine temperature, reaches energy-conservation object.
