SL3NB-1300A mining air bag capsule oilfield drilling mud pump accessories with high pressure resistance

Description :

  The air bag capsule is a key buffering component in the oilfield drilling mud pump system, mainly used to absorb the pressure pulsation generated during the operation of the mud pump, stabilize the discharge manifold pressure, and protect the pump body and pipeline system from impact damage. This model is specifically designed for the SL3NB-1300A three cylinder single acting mud pump, suitable for high load, continuous operation oil drilling conditions. It can effectively extend the service life of the pump valve group and pipeline, ensuring the safety and efficiency of drilling operations.

  The air case capsule is made of high-strength synthetic rubber material, which has excellent oil resistance, wear resistance and aging resistance, and can adapt to the complex and changeable chemical environment underground. Its structural design strictly follows the standards of petroleum drilling and production equipment such as API Spec 7K, and its pressure bearing capacity usually covers the rated working pressure range of mud pumps, with common working pressures reaching over 30MPa. The product undergoes strict vulcanization process to ensure uniform wall thickness and good airtightness of the capsule, which can maintain structural integrity under frequent pressure fluctuations and prevent early rupture or leakage.

When selecting, it is necessary to strictly check the specific model SL3NB-1300A of the mud pump. The interface size and volume of the air case of different brands or series of mud pumps may vary and cannot be used interchangeably. This accessory is suitable for the mud circulation system of various oil drilling rigs and workover rigs, and is not suitable for ordinary industrial water pumps that are not used for drilling. When purchasing, it is necessary to confirm whether to replace only the internal capsule or the outer shell components. This product is an internal rubber capsule accessory, and before installation, it is necessary to check whether there are sharp burrs inside the air case shell to avoid scratching the new capsule.

When installing the air bag capsule, it should be ensured that the pre filled nitrogen pressure meets about 30% -40% of the working pressure of the mud pump to achieve the best buffering effect. In daily maintenance, it is necessary to regularly check the airbag pressure. If the pointer of the pump outlet pressure gauge swings too much, it may indicate that the capsule is damaged or the pressure is insufficient. The machine should be stopped in time for inspection and replacement. It is recommended to establish a regular replacement plan to prevent mud from entering the air casing due to long-term fatigue failure of the capsule, which can cause more difficult to clean faults and ensure continuous drilling operations.
