Description

Technical field

The invention relates to the field of transport engineering and can be used in water-cooled internal combustion engines.

State of the art

A known design of a water pump of an internal combustion engine for pumping coolant (patent RU No. 95032, IPC F01P 5/10, publ. 06/10/2010), comprising a housing, a sealing assembly, a gear pulley, a bearing assembly serving as a pump shaft with an impeller pressed onto it blade type, and the blades are made straightforwardly at least eight, and on the working surface of the flange there are four discharge holes for equalizing the fluid pressure, located between pairs of adjacent blades at equal angular distances nyah, while the back of the impeller is located in the same plane.

The reasons that impede the achievement of the technical solution is the location of the impeller blades to the base at an angle of 90 °, moreover, four holes with a diameter of 8 mm are made on the base of the impeller and there are no stiffeners on the inside.

The prototype of the proposed utility model is a water pump of an internal combustion engine, comprising a housing mechanically machined on metalworking equipment, the surface finish of the housing corresponding to the machining class of the ICE mating surfaces, a gear pulley serving to transmit rotational motion, a bearing assembly with an impeller consisting of a sleeve and blades of thermoplastic material, while the impeller blades in an amount of at least 8 pcs. made at the base with cavitation holes to equalize the pressure drop of the coolant with a diameter of at least 5 mm, the impeller blades have a bend in the direction of rotation with a radius of R24.25 mm, to exclude water hammer during pump operation and create the working area of the impeller, i.e. the reverse side of the impeller hub is made of stiffening ribs in the form of recesses with radii of R25.25 mm, and the beginning of the stiffening ribs and cavitation holes coincide (patent RU 121004, IPC F01P 5/10, publ. 10.10.2012).

The reasons that impede the achievement of the technical result are the deterioration of heat dissipation from the engine, overheating, which leads to a decrease in the life of the engine.

Utility Model Disclosure

The technical problem lies in the development of an internal combustion engine pump, in particular an impeller and a water pump housing, which allows increasing pump performance in all engine operating modes.

The technical result is to increase the heat transfer of the internal combustion engine by increasing the area of the impeller blades and the shortened walls of the water pump housing.

The technical result is achieved by the fact that the water pump comprises a housing, a gear pulley, a locking screw installed in the housing for fixing the bearing, a bearing assembly, an impeller consisting of a sleeve and blades, the beveled corners of the rectangle of the blades in the upper part have an angle with a direction towards another angle which is beveled to the base, while the base of the rectangle has an arcuate shape with a radius of R16 mm, in addition, the reverse side of the impeller contains a recess with a radius of R3 mm and is made in such a way that mounting on the housing of the water pump.

The essence of the technical solution is illustrated in the drawings.

FIG. 1 shows an axial section of a water pump.

FIG. 2 shows a three-dimensional model of a water pump impeller.

FIG. 3 shows a volumetric model of a water pump housing.

FIG. 4 shows a volumetric model of a water pump.

The water pump contains a housing (1), a gear pulley (2), a locking screw (3) installed in the housing for fixing the bearing, a bearing assembly (4), an impeller (5) consisting of a sleeve and blades, and the beveled corners of the rectangle of the blades in the upper part has an angle with a direction in the direction of another angle, which is beveled to the base, while the base of the rectangle has an arcuate shape with a radius of R16 mm, in addition, the reverse side of the impeller contains a recess with a radius of R3 mm and is made in such a way that it can be mounted on Asosa.

Utility Model Implementation

The water pump of the internal combustion engine (Fig. 4) works as follows. The housing 1 of the water pump is mounted on the cylinder block of the internal combustion engine. Torque from the crankshaft of the internal combustion engine is transmitted through the timing belt via a gear pulley 2 to the bearing assembly 4 with the impeller 5 firmly seated on it. Due to the rotation of the impeller 5 of the coolant coming from the radiator and thermostat, acceleration is given and with increased pressure into the cylinder block, thereby ensuring its circulation and cooling of the running engine. The utility model is aimed at increasing the durability of the internal combustion engine, increasing the productivity of the water pump.

Claims (1)

A water pump comprising a housing, a gear pulley, a locking screw installed in a housing for fixing the bearing, a bearing assembly, an impeller consisting of a sleeve and vanes, characterized in that the beveled corners of the rectangle of the vanes in the upper part have an angle with a direction towards another angle, which is beveled to the base, while the base of the rectangle has an arcuate shape with a radius of R16 mm, in addition, the reverse side of the impeller contains a recess with a radius of R3 mm and is made in such a way that it can be installed on the body with a water pump.
