Title
(EN) CARRIER FOR PLUNGER DURING DISASSEMBLY
(FR) SUPPORT POUR PISTON PENDANT LE DÉMONTAGE
Abstract
(EN)
A carrier that holds a plunger for a reciprocating pump during maintenance. Maintenance of the pump typically includes repacking of the packing that surrounds the plunger and revalving of the pump's inlet and outlet valve. To allow repacking or revalving, the pump is disassembled and the plunger is removed. The carrier mates with the pump to hold and support weight of the plunger during disassembly, allowing one person to perform pump revalving and repacking.
(FR)
L'invention concerne un support qui tient un piston de pompe à piston pendant l'entretien. L'entretien de la pompe comprend typiquement le changement de la garniture qui entoure le piston et le changement de la soupape d'entrée et de sortie de la pompe. Pour permettre le changement de garniture ou de soupape, la pompe est démontée et le piston est retiré. Le support s'adapte à la pompe afin de tenir et supporter le poids du piston pendant le démontage, en permettant à une personne d'effectuer le changement de la garniture ou de la soupape de la pompe.
