Abstract

The invention discloses a centrifugal cooling water pump, which comprises a water inlet receiving tray (1), an impeller (2), a volute (3), a bearing (4), a bearing seat (5), a transmission shaft (6), fasteners (7), a high-temperature impeller (8), a hub (9), a low-temperature impeller (10), a water inlet (11), a water inlet (12), a water outlet (13) and a water outlet (14), wherein the water inlet receiving tray (1) is provided with the water inlet (11); the volute (3) is provided with the water inlet (12), and the volute (3) is connected with the water inlet receiving tray (1) and the bearing seat (5) through the fasteners (7); the bearing seat (5) is in interference connection with the bearing (4); the bearing (4) is in interference connection with the transmission shaft (6); the transmission shaft (6) is in interference connection with the impeller (2); and one side of the impeller (2) is provided with the high-temperature impeller (8), the other side of the impeller (2) is provided with the low-temperature impeller (10), and the impeller (2) is axially provided with the hub (9). The centrifugal cooling water pump can improve the temperature balancing capacity of an engine, improve the heat transfer efficiency, reduce the discharge index of an internal-combustion engine, increase the efficiency of the whole machine and reduce the oil consumption.

Description

Technical field: [0001] The invention belongs to the technical field of hydraulic pressure, and in particular relates to a centrifugal cooling water pump. Background technique [0002] At present, the internal combustion engine mainly adopts a single-circuit centrifugal cooling water pump, and the cooling water temperature can only reach a certain index, which cannot meet the temperature requirements of the cooling liquid for different components of the internal combustion engine cooling system. In order to achieve the engine with low fuel consumption and high emission requirements, the body is cooled The temperature of the liquid is increased to above 120°C. On the other hand, the intercooler needs to limit the coolant temperature below 100°C in order to meet the demand for intake air temperature and density, and the oil cooler to meet the demand for oil cooling. The dual-circulation cooling system can meet the temperature requirements of different parts of the cooling syst...
