A chemical injection pump for injecting chemicals into subsea system at depths up to 10,000 feet is described which uses a minimum of moving parts by employing an actuator, for instance a solenoid, to power a double acting actuator rod and plungers thereon. The pump would generate low pressures and low fluid volumes, but be more durable and reliable than conventional rotating pumps operating under subsea conditions.
L'invention concerne une pompe à injection chimique permettant d'injecter des produits chimiques dans un système sous-marin à des profondeurs supérieures à 10 000 pieds, utilisant un minimum d'éléments mobiles, grâce à un dispositif de commande, par exemple, un solénoïde, permettant d'actionner une tige d'asservissement à double effet et des pistons plongeurs disposés dessus. La pompe produit des pressions basses et des volumes fluidiques faibles, mais elle dure plus longtemps et elle est plus fiable que les pompes rotatives classiques exploitées en milieu sous-marin.
