[0034] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings.
[0035] Such as Figure 1 to Figure 4 Shown here is a hydraulic spring operating mechanism proposed in the first embodiment of the present invention, which cooperates with the pressure tester M and includes a working cylinder 1 with oil and a piston rod 2 matched with the working cylinder 1. The working cylinder 1 is provided with an opening pressure test channel 11 and a closing pressure test channel 12 respectively; among them,
[0036] The opening pressure test channel 11 is embedded with a first pressure sensor 111 for real-time acquisition of the dynamic oil hydraulic pressure in the working cylinder 1 during the opening process of the hydraulic spring operating mechanism. The first pressure sensor 111 has a probe at one end of the working cylinder 1. Inside th...
