[0016] The present invention will be described in detail below in conjunction with the drawings.
[0017] Such as Figure 1 to Figure 7 As shown, the cylinder of the static pressure exciter of the present invention includes a cylinder tube 5 and a piston 2 placed in the inner cavity of the cylinder tube. Two seals are used between the cylinder barrel 5 and the piston 2, which can significantly improve the sealing effect. Both ends of the piston 2 are fixedly connected to a piston rod 11 and a piston rod 12. The piston rod 11 and the piston rod 12 are respectively fixedly connected with the piston 2 in a threaded manner. The piston rod 11 and the piston rod 12 respectively extend out of the cylinder 5 Cavity. The hydrostatic bearing 31 is fixedly connected to the end cover 41 by bolts 181 and 182; the hydrostatic bearing 32 is fixedly connected to the end cover 42 by bolts 183 and 184. Such as Figure 5 As shown, the cross-sections of the hydrostatic bearing 31 and the hydrostat...
