液壓扳手畢業設計全套
Abstract
In the energy, the transportation, the metallurgy, the chemical industry, the mine and other professions equipment setups, in the overhaul work, the assembling and dismantling big specification bolt quite is difficult; Some bolts install in the spatial extremely small and narrow place are unable with to lengthen the arm of force or with the method fastening and the disassemblage bolt which hammers; Some equipment long-term use in the quite moist place, the bolt rusts away seriously is unable with the artificial disassemblage, thus overhauls with difficulty; In elevated duct and on high altitude equipment skeleton fastening and disassemblage bolt, staff although wears the safety belt also with difficulty to use the strength, must safely complete the work to be extremely difficult; According to the equipment management authoritative organization statistics, has above 50% in the equipment movement breakdown is because the bolt question causes, but creates the equipment significant accident because of the bolt question the quantity also extremely astonishing, therefore the new equipment setup and the overhaul standard fasten to the bolt the moment of force request quite is strict, but meets the requirements with difficulty with the artificial method.
Above the hydraulic pressure torque spanner solves the question ideal tool. This tool the high-pressure oil which produces with the necessary ultrahigh voltage hydraulic pump takes the power, automatically completes the bolt the fastening and the disassemblage work, steady, does not have the impact, safe, the assembly quality is high
