Record 1 2008-12-02

English

Subject field(s)
  • Non-Artesian Water Wells
  • Equipment and Tools (Water Supply)
CONT

Surge-blocks, swabs, or plungers are disc shaped devices made to fit tightly within the well. Their edges are usually fitted with rubber or leather rings to make a tight seal against the well casing. Pipe sections are then attached to the surge-block to lower it into the well, above the well screen, and about 15 feet below the water level. The assembly is then repeatedly lifted up and down. The up and down action of the surge-block creates suction and compression strokes that force water in and out of the well through the screened interval, gravel pack, and aquifer. It works like a plunger in the way that it removes small obstructions and sediments from the well. The surge-block is slowly lowered each time resistance begins to decrease.

CONT

A rapid up and down motion of a surge block in the water of the well will give reversals of flow through the screen ...

  • Puits autres qu'artésiens (Sources d'eau)
  • Équipement et outillage (Alimentation en eau)

Record 2 2008-02-18

English

Subject field(s)
  • Closing Devices and Nozzles (Mechanical Components)
  • Aeronautical Engineering and Maintenance
DEF

A circular rubber seal with a depressed center surrounded by a raised sealing lip.

CONT

The advantage of the flapper disc seal over the cup-type seal is that the flapper-type seal won’t invert. Occasionally, the cup-style seal will invert and lodge the casing plunger in the production string, necessitating a wireline trip.

OBS

Seals in one direction only allowing fluid to bypass it in the opposite direction.

Key term(s)
  • cup type seal

French

Domaine(s)
  • Obturateurs et buses (Composants mécaniques)
  • Aérotechnique et maintenance
DEF

Joint en caoutchouc, à centre creux et à lèvre circulaire élevée pour une meilleure étanchéité.

OBS

joint-calotte : terme uniformisé par le Comité d'uniformisation de la terminologie aéronautique (CUTA) - Maintenance.

PHR

Joint calotte de pompe, joint calotte en U.

Record 5 1992-10-09

English

Subject field(s)
  • Nuclear Science and Technology
CONT

The channel closures installed on a CANDU reactor shall be locked in place by closure safety locks.... The closure body shall close off the end fitting bore so that any failure of the seal disc does not result in a loss of coolant in excess of the capacity of the make-up system.

French

Domaine(s)
  • Sciences et techniques nucléaires
CONT

Les bouchons de fermeture de canal installés dans un réacteur CANDU doivent être retenus au moyen de verrouillages de sûreté (...) Le corps du bouchon de fermeture doit obturer l'alésage du raccord d'extrémité de sorte qu'aucune défaillance du disque d'étanchéité ne provoque une perte de caloporteur supérieure à la capacité de débit du circuit d'appoint.
