The air bag is also called the exhaust air bag, which is installed in a section of the discharge pipe of the hydraulic end, which plays a good role in stabilizing and compensating pressure. Its working pressure is 80% of the working pressure of the mud pump. F500/F800 mud pumps use KB45 air packs, and F1000/F1300/F1600 use KB75 air packs. It is worth noting that when disassembling the air bag, the pressure must be released first.
The pressure of the airbag inflator is 30% of the design pump pressure, the general pressure is 4~6MPa, and the best pressure is 4.5MPa. During normal working hours of the mud pump, the airbag stop valve is closed to protect the instrument
