Description

Mechanical seal assembly for high-temperature oil pump Technical Field The utility model belongs to the technical field of high-temperature oil pumps, and particularly relates to a mechanical seal assembly for a high-temperature oil pump. Background The high-temperature oil pump consists of pump body, pump cover, internal and external rotors, pump shaft and shaft end combined seal, etc. its main drive is formed from a set of mutually-meshed rotors, and its shaft end seal adopts high-temperature-resisting reflux combined seal, adopts water tank type cooling mode to control shaft seal outlet temperature, and belongs to positive displacement pump. The existing high-temperature oil pump has the defects that when the oil pump is used, an oil inlet is required to be connected with a conveying pipe, the sealing performance of most of connecting parts is poor, the phenomenon of oil seepage can occur after the service time is long, and the use is inconvenient, so that the mechanical sealing component for the high-temperature oil pump is provided. Disclosure of utility model The utility model aims to provide a mechanical seal assembly for a high-temperature oil pump, which aims to solve the problem that most of joints in the background art are poor in sealing performance. In order to achieve the above purpose, the mechanical seal assembly for the high-temperature oil pump comprises a base and a support plate, wherein one end of the base is provided with the support plate, the support plate is fixedly connected with the base, one end of the support plate is provided with a shell, the shell and the support plate are fixed through welding, one side of the shell is provided with an oil inlet, one end of the oil inlet is provided with an oil pipe, one end of the oil inlet is embedded with a seal groove, a first sealing gasket is arranged in the seal groove, the first sealing gasket is made of elastic materials, one end of the oil pipe is provided with an inserting plate, the inserting plate is fixed with the seal groove through insertion, and one end of the inserting plate is provided with a second sealing gasket. Preferably, a sealing plate is arranged in the oil pipe, a third sealing gasket is arranged in the oil inlet, and the third sealing gasket is fixedly connected with the oil inlet. Preferably, a first flange is arranged at one end of the oil pipe, a second flange is arranged at one end of the oil inlet, and the second flange and the first flange are fixed through bolts. Preferably, a motor is arranged at one end of the base, and the motor and the base are fixed through screws. Preferably, the output end of the motor is provided with a rotating shaft, the rotating shaft extends to the inside of the shell, and the top of the shell is provided with an oil outlet.
