Products Description
Introduction of DW Mining Supporting Acrow Prop Single Hydraulic Prop For Sale
1. The working fluid of Underground DN Inner Injection Single Hydraulic Prop is the 5th hydraulic oil, back to the column when the hydraulic oil flow back into the cylinder plunger cavity to form a closed loop;zmwm15
2. Does not require pumping and piping systems, auxiliary equipment, low cost; 3. Mains and pumping stations in the absence of local still use, flexibility, easy management and simple;
4. Since the working fluid is a closed loop, prop prop hydraulic oil flowing back when the plunger cavity pillar itself to achieve closed loop hydraulic oil, hydraulic oil consumes very little;
5. Prop hydraulic system for the closed system, hydraulic oil does not spill, do not pollute the environment, environmental protection, and face the production of small, well maintained face environment, better working conditions;
6. Prop valve is fully installed in the pillar cavity , the possibility of contamination by outside the small, high reliability.
