Prop demolition column machine is a single prop repair business produced a good helper, demolition column work efficiency can be greatly increased corporate earnings. Hydraulic prop demolition column machine technology features introduced please log in Tai'an City Mechanical and Electrical Equipment Co., Warner official website to see three valves test rig at: http:? //www.tahnjd.com/product.asp Pro = 35 single hydraulic Pillar demolition column machine is a hydraulic prop demolition column dedicated equipment, it can disassemble severe corrosion, with the demolition of the pillars of the existing equipment is difficult to make the process of demolition column basically realized mechanization computer three valves test rig, to accelerate the demolition column and repair process, is the better one split column device. To complete the three valves, base, handle body, cover and live cylinder disassembly task with three valves test rig manufacturing, to achieve a machine can. Hydraulic props single cylinder test items and technical standards Live detection items and technical standard column monomer hydraulic prop 1 outer diameter dimensions and tolerances should be φ92h9. 2 the outer diameter surface of the pits or scratches to allow a slight scratch depth of less than 0.5mm. 3 bottom nozzle dimensions and tolerances should be φ80h9 bottom port φ80h9 cylindrical surface rust is not allowed. 4 port 15 ° chamfer at the bottom roughness Ra≤6.3μm. 5 Surface hardness HB270 ~ 310. 6 coating thickness should be 45 ~ 60μm. 7 valve hole dimensions and tolerances φ42H9 8 plating look no blistering, peeling, flaking, burning and other defects and severe bruising and other mechanical damage. 9 runout <2mm. 10 hyperbaric welding test, 1.5 times the rated working fluid pressure retaining 2min no leakage. 11 stigma hardness of HB240 ~ 270. 12 bottom nozzle φ80 hole ovality of not more than 0.1mm.
