Abstract
The utility model discloses a kind of engine water pump, including impeller housing, impeller and water pump shell, the impeller is fixedly mounted in impeller housing, and in the cavity formed after impeller housing with water pump shell fastening, delivery port is provided with the outer wall of the water pump shell, pump aquaporin between the installation cavity of the impeller and delivery port by inclining is connected, and the pump aquaporin is gradually increased to the direction of water pump shell from impeller housing apart from the distance of water pump axis, and pump aquaporin interior smooth is without bending.The pump aquaporin that the pump aquaporin of former right-angled corner is become inclined, the water flowing for pumping out impeller is more smooth, simultaneously, due to the change of pump aquaporin so that former narrow pump aquaporin becomes more spacious, significantly reduces flow resistance, increase channel cross-section, and then pump outlet capacity is improve, contain the pinking that engine abnormity burning is produced, improve the life-span of engine.
Description
Technical field
The utility model is related to engine component, and in particular to a kind of engine water pump configuration.
Background technology
Engine water pump is used for cooling down engine, prevents indicating oven temp. of engine and breaks down.The work of engine water pump is former
Reason：Water pump bearing and wheel rotation are driven by belt pulley, the coolant in water pump is driven by impeller and rotated together, in centrifugal force
In the presence of be thrown toward the edge of water pump cover, while producing certain pressure, then flow out from water outlet or water pipe.Impeller
Center reduced pressure as coolant is thrown out of, the coolant in water tank is in unit fixed on water pump suction and the differential pressure action of impeller central
The lower reciprocation cycle for being inhaled in impeller through water pipe, realizing coolant.
In conjunction with shown in Fig. 3, Fig. 4, existing engine water pump is made up of impeller housing 1, water pump shell 3 and impeller 2.Impeller 2 is solid
Dingan County is mounted in impeller housing 1, and in the cavity formed after impeller housing 1 with the fastening of water pump shell 3, is set on the side wall of water pump shell 3
It is equipped with delivery port 4.Connected by the pump Aquaporin-5 of right-angled corner between the installation cavity of impeller 2 and delivery port 4.2 rotating band of impeller
Water is pumped out by the water in movable vane piece in the effect of centrifugal force, due to the structure of water pump shell 3 unreasonable, water pump inefficient,
In the more aobvious protrusion of the slow-speed of revolution, during low speed, pump outlet capacity is not enough, causes engine to be susceptible to abnormal combustion in 1500-2300 rotating speeds interval
Burn, produce pinking, affect engine work, reduce engine ordinary life.
Utility model content
When the utility model aims to solve the problem that low engine speeds, because water pump pump outlet capacity is not enough, abnormal combustion and quick-fried is produced
The problem of shake.
For this purpose, the technical scheme that adopted of the utility model for：A kind of engine water pump, including impeller housing, impeller and water
Pump case, the impeller are fixedly mounted in impeller housing, and in the cavity formed after impeller housing with water pump shell fastening, the water
Delivery port is provided with the outer wall of pump case, and the pump aquaporin between the installation cavity of the impeller and delivery port by inclining is connected,
The pump aquaporin is gradually increased to the direction of water pump shell from impeller housing apart from the distance of water pump axis, and pump aquaporin interior lights
Slide without bending.
Used as the preferred of such scheme, the pump aquaporin is 30～45 ° with the angle of water pump axis, the delivery port
For mounting hole, and the length direction of mounting hole is vertical with water pump axis.By limit pump aquaporin and water pump axis angle and
The shape size of delivery port, on the premise of not increasing water pump shell length, further improves pump outlet capacity, makes current more smooth.
Further, be provided with the lateral wall of the impeller housing some be parallel to each other and axially extending reinforcement, and plus
The thickness of strong muscle is gradually increased from impeller housing to the direction of water pump shell, increases the intensity of impeller housing, especially near water pump shell one
The intensity of side, improves the service life of water pump.
The beneficial effects of the utility model：The pump aquaporin that the pump aquaporin of former right-angled corner is become inclined, makes impeller
The water flowing for pumping out is more smooth, simultaneously as the change of pump aquaporin so that former narrow pump aquaporin becomes more to widen
Spacious, flow resistance is significantly reduced, channel cross-section is increased, and then is improve pump outlet capacity, contained engine abnormity burning
The pinking of generation, improves the life-span of engine.

Specific embodiment
Below by embodiment and accompanying drawing is combined, the utility model is described in further detail：
In conjunction with shown in Fig. 1, Fig. 2, a kind of engine water pump is mainly made up of impeller housing 1, impeller 2 and water pump shell 3.Impeller 2
It is fixedly mounted in impeller housing 1, and in the cavity formed after impeller housing 1 with the fastening of water pump shell 3, impeller housing 1 is led to impeller 2
Cross circumferentially disposed screw lock together, on the side wall of water pump shell 3, be provided with delivery port 4, consistent with the structure before improvement.
Difference is：Pump Aquaporin-5 between the installation cavity of impeller 2 and delivery port 4 by inclining is connected, pump Aquaporin-5
Distance apart from water pump axis is gradually increased from impeller housing 1 to the direction of water pump shell 3, and pump Aquaporin-5 interior smooth is without bending.
Pump Aquaporin-5 is preferably 30～45 ° with the angle of water pump axis；Delivery port 4 for mounting hole, and the length of mounting hole
Degree direction is vertical with water pump axis, on the premise of 3 length of water pump shell is not increased, increases the cross section of delivery port.
In addition, be provided with the lateral wall of impeller housing 1 some be parallel to each other and axially extending reinforcement 6, and reinforcement 6
Thickness gradually increased from impeller housing 1 to the direction of water pump shell 3, increase the intensity of whole impeller housing 1, especially near water pump
The intensity of the impeller housing 1 of 3 side of shell.
