Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of automobile engine, concretely is automobile water pump with volute structure. BACKGROUND

[0002] In the cylinder body of automobile engine, there are multiple water channels for circulating cooling water, which are connected with the radiator (commonly known as water tank) placed in the front part of the automobile through water pipes to form a large water circulation system. A water pump is installed at the upper water outlet of the engine. The water pump is driven by the fan belt to pump out the hot water in the cylinder body water channel and pump in the cold water. There is also a thermostat beside the water pump. When the automobile is just started (cold car), the thermostat is not opened, and the cooling water does not pass through the water tank, but only circulates in the engine (commonly known as small circulation). When the temperature of the engine reaches above 95 degrees, the thermostat is opened, and the hot water in the engine is pumped into the water tank. The cold wind blowing through the water tank when the automobile is running carries away the heat. The engine drives the water pump bearing and impeller to rotate through the belt pulley. The cooling liquid in the water pump is rotated together by the impeller under the action of centrifugal force and is thrown to the edge of the water pump housing. At the same time, a certain pressure is generated, and then the cooling liquid flows out from the water outlet or water pipe. The center of the impeller is under reduced pressure due to the ejection of the cooling liquid. The cooling liquid in the water tank is sucked into the impeller through the water pipe under the pressure difference between the water pump inlet and the center of the impeller, realizing the reciprocating circulation of the cooling liquid.

[0003] Application No. CN202221332370.1 discloses a composite volute for testing automobile water pump assembly, which comprises a support and a volute model fixed on the support to form a composite volute. The volute model is connected with the water pump cover assembly through the support to form a water pump assembly. The support is composed of a bottom plate and a support plate. The support plate is vertically fixed on the bottom plate and has a hole through which the impeller passes. One side of the support plate is sealingly connected with the volute model, and the other side of the support plate is used to connect the water pump cover assembly. The volute model comprises an aluminum alloy block, and a volute cavity is formed on the bonding surface of the aluminum alloy block. Compared with the existing mode, the composite volute does not need to wait for the engine cylinder body to be cast into shape, which can shorten the research and development period. The volute model is made of aluminum alloy block, which can reduce the research and development cost. The utility model has the advantages of simple structure, low manufacturing cost and good universality.

[0004] Although the above-mentioned utility model has the advantages of adopting a composite volute, not needing to wait for the engine cylinder body to be cast into shape, which can shorten the research and development period, and adopting an aluminum alloy block to make a volute model, which can reduce the research and development cost, the utility model has the disadvantage that when the device is used and connected externally, there is a possibility of looseness through the conventional bolt connection, which cannot provide further protection.
