The environment of industry selects most suitable hydraulic breaking hammer, and when backward stroke of the piston starts, the impact of piston last time is over, and is in wink
When standstill state, main valve chamber is low pressure chamber at this time, and V4 chamber is normal high pressure chest, therefore main valve plug is in lower limit position, in this way,
Piston ante-chamber is communicated by main valve plug with high pressure oil, and piston back cavity is communicated with oil back chamber always, is low pressure, therefore piston is in ante-chamber
Under the action of high pressure oil, make backhaul accelerated motion, while compressing tail portion nitrogen chamber nitrogen, is allowed to make adiabatic compression, piston is in height
Continued up under the action of pressure oil and make drawback movement, when piston middle section downside cross control mouth it is following when, high pressure in chamber
Oil enters the chamber of main valve, since the hydraulic coupling that transit chamber acts on main valve plug is greater than the hydraulic coupling that chamber acts on main valve plug, thus
Spool is forced to start commutation movement, the movement of spool is gradually decreased into the high pressure oil in chamber, so that respective action is on piston
Backhaul thrust be also gradually reduced, and the backhaul resistance that applies of compressed nitrogen relatively is increasing, and piston is just transferred to back
Journey deboost phase, the pressure oil that spool will finally be completely cut through in chamber, piston will stop drawback movement quickly.
On the basis of the technical conditions of existing quartering hammer cylinder body, still remained in the range and convenience used
Many insufficient, most of quartering hammer cylinder interior is mostly integral structure, leads to internal nitrogen since volume is smaller in structure
Necessary requirement is not achieved in room, is inconvenient, and traditional cylinder interior damping property is poor, and it is existing to be often easy to happen internal rupture
As influencing the normal use of equipment.
