This invention belongs to the field of transmission system sealing technology and proposes a brush-type sealing structure for rotary sealing. It includes an outer retaining ring, an inner retaining ring, a first upper brush fixing ring, a second upper brush fixing ring, a first lower brush fixing ring, a second lower brush fixing ring, an upper brush filament bundle, and a lower brush filament bundle. The outer retaining ring is composed of a side wall and a bottom wall. The inner retaining ring is located in the middle of the side wall of the outer retaining ring. The second upper brush fixing ring is located on the upper surface of the upper surface of the inner retaining ring, and the second lower brush fixing ring is located on the lower surface of the inner retaining ring. The first lower brush fixing ring is located on the upper surface of the bottom wall of the outer retaining ring. The first upper brush fixing ring is located at an opening in the side wall of the outer retaining ring. An upper brush filament bundle is located between the first and second upper brush fixing rings, and a lower brush filament bundle is located between the first and second lower brush fixing rings. This brush-type sealing structure can simultaneously meet the high-temperature sealing requirements of both static and rotating interfaces, significantly reducing the risk of leakage and achieving long-term stable operation of the system.

The utility model discloses a device convenient for online maintenance of a bucket elevator, which comprises an outer shell, an oil recharging assembly is arranged on the inner side of the outer shell, and a monitoring assembly is arranged above the oil recharging assembly, and relates to the technical field of online maintenance of bucket elevators. According to the device facilitating online overhauling of the bucket elevator, through cooperative operation of the integrated monitoring assembly and the oil supplementing assembly, a closed-loop management system for chain state monitoring and dynamic lubrication is built, the device can monitor the tension of the chain in real time and synchronously feed back the tension to the control system, the control system controls the oil supplementing assembly, and the oil supplementing efficiency is improved. Compared with a traditional manual inspection mode, manual inspection frequency can be greatly reduced, shutdown maintenance time can be shortened, operation and maintenance efficiency can be remarkably improved, operation continuity of the bucket elevator and stability of the production rhythm are effectively guaranteed, meanwhile, the oil supplementing assembly can accurately control the oil quantity, and the oil supplementing efficiency is improved. And the conditions of insufficient oil injection and excessive oil injection are prevented.

This invention relates to the field of pump equipment technology, specifically to a high-temperature dual-suction centrifugal pump combined flushing structure, comprising: a dual-suction centrifugal pump, connected to a sealed cavity and a drive component; a first cyclone self-cleaning heat exchanger and a second cyclone self-cleaning heat exchanger, respectively connected to both ends of the sealed cavity, a cooling water inlet, and a cooling water outlet; a first liquid storage tank and a second liquid storage tank, respectively connected to both ends of the sealed cavity, a cooling water inlet, and a cooling water outlet; and a level gauge, a pressure detection element, and a thermometer, all mounted on the first and second liquid storage tanks. By integrating a self-cleaning structure that utilizes the kinetic energy of the flushing fluid to continuously peel off polymer deposits on the pipe wall, an anti-clogging cooling flow channel with online self-sustaining capability is established, fundamentally eliminating the flushing flow rate attenuation problem caused by localized cooling and coking of aromatics, ensuring that the inner mechanical seal always receives stable and sufficient cooling and lubrication throughout the entire operating cycle.

This invention relates to the field of storage technology and discloses a protective device for a storage server and a storage server cabinet. The device includes a fixed frame with a movable frame inside, the movable frame being detachably connected to the chassis. Both the fixed and movable frames are U-shaped structures. The device also includes an auxiliary fixing mechanism and a buffer support mechanism. The buffer support mechanism includes an inclined guide groove disposed on the side wall of the movable frame, with two symmetrically arranged inclined guide grooves on the same side of the movable frame. The side wall of the fixed frame is provided with a support shaft that slides along the inner side of the inclined guide groove. This invention, through the cooperation of the inclined guide groove and the support shaft driven by a return spring, converts vertical vibration into horizontal elastic potential energy, achieving efficient multi-dimensional buffering and significantly reducing the risk of data loss due to hard drive vibration. For chassis of different weights, it provides direct push-in or step-by-step lifting installation schemes, and the rotating connection of the support shaft makes assembly smooth and convenient.

The invention belongs to the technical field of liquid lead-based cooling reactors, and particularly relates to an integrated lead-based coolant efficient purification device. The heat exchanger comprises an outer shell, the upper end and the lower end of the outer shell are connected with an upper sealing head and a lower sealing head respectively, an inner flow channel is installed in the outer shell, a bottom heat exchange tube bundle is arranged below the inner flow channel, and the bottom heat exchange tube bundle is communicated with the inner flow channel and the lower sealing head respectively; and a filtering assembly is arranged in the inner flow channel. The liquid lead-based metal cooling agent purification device can realize functional partition of bottom heat exchange, middle cooling and top trapping, and has the characteristics that the temperature of the cooling area can be adjusted in a grading manner, the filter assembly is detachable and the like, so that dissolved impurities in the liquid lead-based metal cooling agent can be efficiently and deeply purified.
