This application belongs to the field of welding technology and discloses a conductive tip disassembly and feeding device and a conductive tip replacement equipment. The conductive tip disassembly and feeding device includes a conductive tip disassembly and feeding mechanism, a conductive tip feeding mechanism, and a position switching mechanism. The position switching mechanism drives the conductive tip feeding mechanism to move along a first horizontal direction, enabling the feeding mechanism to have a loading position for delivering new conductive tips to the disassembly and feeding mechanism and a waiting position to avoid the disassembly and feeding mechanism. The disassembly and feeding mechanism removes the conductive tip from the welding torch or installs a new conductive tip onto the welding torch. Only one disassembly and feeding mechanism is needed to achieve the disassembly and assembly of the conductive tip, allowing for disassembly and assembly at the same workstation, improving work efficiency. Furthermore, both the feeding mechanism and the position switching mechanism are located below the disassembly and feeding mechanism, making the overall structure more compact and space-saving.

The input terminal of the pre-charge unit is connected to the load switch, and the output terminal is connected to the phase-shifting transformer. A cooling system provides cooling for the phase-shifting transformer and the medium-voltage frequency converter. This invention also discloses a control method for the vehicle-mounted high-power electric drive system. This vehicle-mounted high-power electric drive system and its control method enable the integrated vehicle-mounted operation of a high-power, high-displacement fracturing pump skid and its drive system in the fracturing engineering field, significantly reducing on-site work intensity, lowering operating costs, and mitigating on-site risks.

This utility model discloses a pulse-jet baghouse dust collector for powder collection. It constructs a zoned airflow channel by symmetrically distributing a first and second side chamber, a first and second air duct group within the central chamber, and a first and second air supply pipeline connecting the first and second bag groups respectively. This is achieved through the control of the first and second butterfly valves in the first and second valve groups. The traditional perforated air chamber structure is eliminated, and a split-pipe connection is used, eliminating dust leakage paths at the source. The replacement of lift valves with butterfly valves significantly improves valve reliability and reduces downtime maintenance frequency. The symmetrical chamber layout and rigid structure synergistically enhance overall sealing and load-bearing capacity, thus comprehensively solving problems of leakage, valve failure, and deformation, achieving efficient and stable dust collection.
