When you buy DW single hydraulic prop, can't assemble, disassemble how to do? Small make up to teach you. This issue is about DW single hydraulic prop assembly and disassembly. DW monomer hydraulic prop is a new type of constant resistance monomer hydraulic prop with external liquid supply, which is the supporting equipment of mechanized general mining working face as well as the end support equipment of fully mechanized mining working face. Let's take a look at the overall assembly and disassembly of DW single hydraulic prop.
Integral assembly of DW single hydraulic prop:
(1) put the assembled live cylinder into the oil cylinder as a whole, install the handle body and put on the connecting wire;
(2) put the top cover into the live cylinder, and connect it with the elastic cylinder pin. All the elastic cylinder pins are not allowed to be exposed, and their openings should be perpendicular to the axial direction of the pillar. And pay attention to make the axis of the 126X126 square body of the top cover parallel to the axis of the cylinder valve hole;
(3) hang the reset spring on the spring ring of the base, load the base into the oil cylinder, and wear the steel wire of the base;
(4) install the three-use valve and make the unloading hole axis of the three-use valve perpendicular to the pillar axis;
(5) after assembly, place the support pillar horizontally and pull the live column from the oil cylinder by hand 300 ~ 400mm (less pull out the lower support column). The live column should be retracted automatically under the action of the reset spring. If it cannot be fully retracted, disassemble it and find out the reason.
Disassembly of DW single hydraulic prop
The disassembly of the pillar can be carried out according to the opposite procedure of assembly, but attention should be paid to:
1. The removal of the base shall be done with the live cylinder ejector.
2. First, draw the live column to * large height, and then remove the handle body to avoid piston scraping the oil cylinder.
3. Piston removal tools should be used when disassembling the piston.
