Detailed Product Description: | Hydraulic prop, hydraulic prop manufacturers Sichuan, suspension hydraulic prop manufacturers, hydraulic prop 0.6 m, 2.8 m fiberglass hydraulic prop, three valves, hinged roof beams, suspended monomer nylon column shoes Since the advent of hydraulic prop, after the mine use by the majority of users. Due to the mine's underground conditions vary, some use of units of the product put forward higher requirements, particularly strength to live the column. In response to this technical difficulties, I founded technical group, by a variety, a large number of tests, and finally developed a special heat treatment process, so that the surface hardness of the plunger from 28-30 ° up to 43-45 °, very effectively improving the pillars of "Artillery collapse", "bending" the ability to extend the life of the product, greatly reducing product failure rates. ? Suspending Prop Model meaning: the difference between the rated working resistance pillar DWX suspension DW31.5-350 / 110X external D- W- representative on behalf of hydraulic prop injection type 31.5- to a maximum height of 110 as the pillar of the pillars and other internal note advantage pillars, pillars outside Note: 1) eliminating the pillar caused due to internal leakage virtual roof, off the top, smothered wounding accidents; 2) large hydraulic work schedule, expanding the scope and improve the recovery rate of coal resources ; 3) In the case of the pillars supporting the high-pressure, and the greater the pressure seal more tightly; 4) the use of a plunger (suspension) technical principles, higher pillar of stability and security; strength 5) column and higher reliability avoid the roof collapse, etc. due to the weld fatigue fracture caused by accidents; 6) sliding seal point compensation and sealed with a seal swelling technical principles. Improve the safety performance of the sliding seals and seal point reduction in the seal replacement rate; 7) greatly reduces the labor intensity of the miners; 8) suspension Prop working medium groundwater, avoiding mine working environment and groundwater pollution; 9) liquid column play a very good cushioning effect and improve the safety of the coal face; 10) using a special hardening treatment process, increase column strength, greatly improving safety; 11) DWX Series suspended Prop extremely low failure rates. Factory direct supplier obvious price advantage, factory direct.
