Problems solved by technology
This connection method has a disadvantage. When the leak of the assembly is confirmed to be caused by the seal groove or the seal ring and needs to be replaced, because the seal groove is coated with sealant, the original structure pattern and the seal ring will be destroyed, and the replacement will not be possible, resulting in overall waste. If the sealant is applied unevenly and the compression deformation of the sealing ring is inconsistent, it will provide a leakage channel for the liquid or air in the chamber, which will cause the assembly to leak instead. There is a problem of improving the disassembly and replacement of the sealing ring, but the sealing effect still not good

The invention discloses an engine water pump sealing gasket which comprises a gasket body. A hole is formed in the gasket body, a protruding pillar is arranged in the hole in a penetrating mode, the sealing gasket is arranged between a water pump shell and a shaft sleeve, bosses are arranged at the upper end and the lower end of the sealing gasket, the bosses are connected with grooves in a matched mode, and arc grooves are formed in left arms and right arms of the bosses. According to the engine water pump sealing gasket, the detachable sealing gasket is arranged between the water pump shell and the shaft sleeve, and therefore the sealing effect can be achieved, and detachment is convenient.
Description
technical field [0001] The invention relates to the technical field of engine components, in particular to an engine water pump sealing gasket. Background technique [0002] The water pump casing of the automobile engine is a die-casting molded part. Whenever the water pump assembly is connected to the cylinder body, the gap between the two rigid parts is sealed by a rubber sealing ring to ensure that the cooling liquid does not leak out. Usually, an adhesive is applied to the sealing groove of the pump casing to bond the sealing ring, so that the sealing ring is not easy to fall off during the inversion, transportation and assembly of the water pump assembly, so as to ensure the integrity of the assembly. This connection method has a disadvantage. When the leak of the assembly is confirmed to be caused by the seal groove or the seal ring and needs to be replaced, because the seal groove is coated with sealant, the original structure pattern and the seal ring will be destroy...
