Hydraulic Diaphragm Drilling Rig Spare Parts NXQ-AB-40/31.5-L-Y Accumulator
Accumulator description of Drilling Rig Spare Parts
The accumulator is an essential and important component in the hydraulic transmission system. It has the functions of storing energy, stabilizing pressure, absorbing hydraulic shock, eliminating hydraulic pulsation, and reducing power consumption.
NXQ- accumulator cavity is divided into two parts by the bladder: the bladder is filled with nitrogen, and the bladder is filled with hydraulic oil. When the hydraulic pump presses the hydraulic oil into the animal energy device, the bladder is deformed under pressure, the volume of the gas decreases with the increase of the pressure, and the hydraulic oil is gradually stored. If the hydraulic system needs hydraulic oil, the energy device will discharge the hydraulic oil to compensate the energy of the system.

In the formula:
P1=accumulator charging pressure
P2=minimum working pressure of the system
P3=maximum working pressure of the system
Inflation pressure
Shock absorbing - the normal pressure of the energy generator set
point or a slightly higher pressure is used as the inflation
pressure;
pulsation absorption - 60% of the average pressure of the pulsation
is used as the inflation pressure;
energy storage - the inflation pressure should be lower than the
system minimum 90% of the working pressure and 25% higher than the
maximum working pressure.
Capacity selection:
When the liquid is flushed or drained slowly by the animal energy
device, it is enough to allow the nitrogen to fully exchange heat
with the surrounding environment when it is pressurized or
depressurized, so that the working temperature remains constant.
This is an isothermal change. On the contrary, when The animal
energy device is filled and discharged quickly, so that the
nitrogen cannot fully exchange heat with the surrounding
environment when it is pressurized or depressurized, which is an
adiabatic change.
