The recent equipment failures are mainly based on the breakdown of locomotives, vehicles, and electricity. In this regard, the Ministry of Railways requires that the maintenance system continue to strengthen the analysis of broken machines and quality management, strictly implement the requirements for the organization and analysis of passengers and buses to break the competent director, continue to carry out in-depth mechanization activities, and vigorously eliminate locomotive running parts and roof high-voltage equipment. Direct supply equipment quality risks, improve the quality of on-line application. Vehicle systems should strengthen safety precautions such as inertial faults of passenger car fires, hot wheels of trucks, bearing failures of EMUs, and failures of traction systems to ensure safe operation. The telecommunications system must conduct in-depth analysis of the recent multiple failures and study and formulate rectification measures.
Mist haze has increased since autumn. The Ministry of Railways pointed out that the power supply system should continue to do a good job in anti-fog work to prevent the occurrence of large-area pollution flashes, strengthen the daily inspection and maintenance of equipment, and increase the cleaning and wiping of insulation equipment on the contact network according to the pollution along the line. In view of the current day and night temperature difference characteristics, power supply system units should promptly check the clues, strengthen the line inspection, segmentation, phase separation, jumper and contact network connections and other key parts of the inspection tour to ensure stable operation of the power supply equipment .
There have been many problems with railroad derailment recently. The Ministry of Railways emphasized that the public works system should focus on preventing the rails from breaking off, and carry out a notorious check on the state of the rails, welds, and joints on the lines, focusing on the existing serious injuries, minor injuries, minor injuries, and fish scale damage. , Combine with the comprehensive inspection of daily inspections, scientifically formulate repair plans and emergency response plans to ensure that the rails are in good condition.
Metal filler is a material used to fill chemical equipment such as tower reactors, adsorbers, and distillation towers. They are usually made of metal wires, wire mesh, or metal sheets, with a high surface area and open pore structure, which can increase the contact area and reaction rate of chemical reactions or adsorption processes. Metal fillers are typically used in the following areas:
1. Distillation: Metal fillers can improve the efficiency and output of distillation towers, reduce energy consumption and operating costs.
2. Adsorption: Metal fillers can be used to prepare various adsorbents, such as activated carbon, molecular sieves, etc., for adsorption and separation of impurities in gases or liquids.
3. Reaction: Metal fillers can be used for catalytic reactions, such as preparing synthesis gas and cracking hydrocarbons.
4. Mass transfer: Metal fillers can be used for mass transfer processes, such as gas absorption, extraction, etc.
The advantages of metal fillers include high surface area, open pore structure, good mass transfer performance, good corrosion resistance, and easy cleaning and maintenance.Metal Structured Packing,Wire Mesh Structural Packing,Ceramic Corrugated Structured Packing,350 Y Structured Packing
