Novel large-displacement radial plunger pump

The invention relates to the technical field of plunger pumps, in particular to a novel large-displacement radial plunger pump which comprises a plunger pump body, an output panel and a driving shaft, an oil inlet cover is arranged on the back of an oil inlet pipeline, the back of the plunger pump body is connected with an oil inlet sealing plate, and the back of the oil inlet sealing plate is in threaded connection with a sealing bolt; an oil inlet bolt hole is further formed in the back of the plunger pump, a through groove with the diameter the same as that of the oil inlet cover is formed in the center of the oil inlet sealing plate, and the sealing bolt penetrates through the oil inlet sealing plate and extends into the oil inlet bolt hole. According to the novel large-displacement radial plunger pump, when the oil inlet pipeline is closed, the oil inlet sealing plate covers the back of the oil inlet pipeline, the sealing bolt is connected to the back of the oil inlet sealing plate in a threaded mode, th
