blacoh pulsation dampener

General material is NBR, the high pressure series material is HNBR. (Item 11)

1.Application

Reduce the drilling pump pressure fluctuations of instantaneous displacement change;Make the pump pressure smoothly, protect equipment from damage caused by severe vibration. 

Filled with nitrogen in the air or inert gas, in the absence of them,air can replace.But oxygen or combustible gas is forbidden. 

2.Pressure

Inflation pressure is 20% ~ 30% of the maximum working pressure. The advanced filling pressure is 2.0-2.5 MPa.

3.Air bladder replacing for discharge dampener

• Make sure there is no pressure in the system
• Disassemble the cover of dampener.
• take out the air bladder
• Check whether the air bladder is damaged or not. Eliminate the damage factor.
• Check the bottom plug condition and the edge should be smooth.
• install the new air bladder
• Install the upper cover and make sure the air bladder is not distorted and extruded
• Screw down the bolts
• Charge it
