A wire harness wall-passing structure and an installation method thereof. The wire harness wall-passing structure comprises: a sleeve pipe, a pouring sealant, and at least one sealing plug, wherein the sleeve pipe is alternately filled with the pouring sealant and the sealing plug along the axis direction of the sleeve pipe; and at least one first through hole formed in the sealing plug, and a wire harness which can penetrate through the pouring sealant and the first through hole in the sealing plug. According to the wire harness wall-passing structure, the sleeve pipe is filled with the pouring sealant and the sealing plug, so multi-stage sealing and multi-time sealing of the wire harness are achieved, the sealing performance of the wall-passing structure is greatly improved, and the wire harness wall-passing structure is more suitable for to-be-fixed devices such as a high pressure vessel.

A piston press system and a test method using the same are used for predicting the roll service life of high-pressure grinding rolls. The method is based on the same comminution mechanism of inter-particle layers compression as the heavy equipment high-pressure grinding rolls to simulate the grinding process of the studded high-pressure grinding roll, realizing that the coverage area of studs accounts for 16% to 20% of the compression surface by disposing tungsten carbide upper studs and lower studs, better restoring the simulation process and effectively realizing the roll service life prediction of the heavy equipment high-pressure roller mill with a small quantity of materials.
