Definitions

  • the instant invention is designed for used with plural component dispensing systems. Previous designs used a single ISO lube housing piece with a small access hole to get at the coupler piece. This hole was plugged during operation and needed to be removed with a tool before servicing. A tool was needed to remove the coupler pin through the access hole.
  • An enclosure will be used to pump throat seal liquid (TSL) on a hydraulic pumpline.
  • the housing will telescope to allow for easier and faster access to the pump coupler without the use of tools.
  • the ISO Lube pump is required on any pump containing moisture sensitive chemicals, such as isocyanates, in order to isolate the chemical from moisture. While in operation the ISO lube housing will be completely filled with ISO lube.
  • the coupler piece which connects the hydraulic piston rod to the chemical rod, needs to be removed in order to service the chemical or hydraulic pump. Fluid must first be drained from the enclosure, and then the locking nut can be removed by backing it away from the large housing piece. Then the two housing pieces can be loosened by hand. When the end of the thread is reached, the small housing collapses into the large housing, allowing easy access to the rod coupler. See Figure 2 for a view of the collapsed enclosure.
  • the 3 piece design utilizes knurled surfaces to eliminate the need for tools. It is also telescoping so the coupler piece can easily be serviced without the need for a small access hole or any tools.
  • Figure 1 shows a cross-section of the pump coupler with the enclosure of the instant invention positioned for operation.
  • Figure 2 shows a cross-section of the pump coupler with the enclosure of the instant invention positioned for maintenance.
  • An enclosure 10 will be used to pump throat seal liquid (TSL) 12 on a hydraulic pumpline 14. While in operation the ISO (isocyanates) lube housing 16 will be completely filled with ISO lube 12.
  • the 3 piece design utilizes knurled surfaces 34 to eliminate the need for tools. It is also telescoping so the coupler piece 18 can easily be serviced without the need for a small access hole or any tools.

Abstract

L'invention porte sur une enceinte (16) pour renfermer un coupleur (18) entre une tige d'entraînement (20) et une tige entraînée (22), laquelle enceinte comprend une première et une deuxième pièce de préférence cylindriques (30, 28). Lesdites pièces sont dimensionnées de telle sorte que la première pièce (30) est apte à coulisser de façon télescopique à l'intérieur de la deuxième pièce (28), et sont filetées de façon à venir mutuellement en prise lorsque, lors du fonctionnement, l'enceinte (16) est dans une position fermée, ce par quoi l'enceinte (16) est apte à maintenir un lubrifiant à l'intérieur. Pour l'entretien, après avoir évacué le lubrifiant à partir de l'enceinte (16), les deux pièces sont desserrées par vissage de la première pièce (30) jusqu'à ce que l'extrémité du filetage soit atteinte, après quoi l'on fait coulisser de façon télescopique la première pièce (30) dans la deuxième pièce (28), de façon à mettre ainsi l'enceinte (16) dans une position ouverte et à permettre l'accès facile au coupleur de tiges (18).
