Centrifugal pump rubber flexible joints

Rubber flexible joints are selected at the entrance and exit of centrifugal pumps and at the corners of pipelines, with connectors and positioning connectors in rolling pipeline connections, without fixed docks, endless docks and positioning dock support brackets. Since the joint can transmit the blind thrust when starting the pump to all positions of the pump and pipeline according to the foot bolt, it prevents the thrust from being concentrated at the corner of the pipeline or on the near side of the pump, causing impact damage to mechanical equipment. In fact, in a variety of pipeline applications, in the pipeline connection has its interaction, the pipeline operation to play the role of shrinkage compensation offset, because they have this correlation in the pipeline connection, so they have complementary and exchange of alternative roles in the pipeline connection applications, only in special circumstances to choose the type, specification series of pipeline connector applications. Most design solution companies and installation engineering companies base their decision on the location of the pipeline connector and whether the connector is in the corner of the rolling pipe and in the middle of the centrifugal pump gate valve, and whether there are fixed fixed piers, endless piers and positioning piers support brackets in the pipeline.
Flange type rubber flexible joint is the equipment of coupling pipeline consisting of itself, sealing ring and snap-on prefabricated components. The compensation connector is suitable for digesting and absorbing the offset and cannot bear the force driving force. After installation on the pipeline, tighten the nut ductile seal ring, under the action of the nut cover, outside the pipeline sealing and connection effect of mutual inclination. When the ambient temperature changes, the pipeline can expand at will in the middle of the joint, and when the foundation settles, the pipeline can be tilted to ensure that there is no leakage of the seal, and then play the purpose of automatic compensation. The rubber flexible joint has a long service life, and the fatigue service life is very with the pipeline. The rolling surface layer is uniquely solved and has good corrosion resistance in physiological saline, solution and other conditions, which is more than 50 times higher than that of low alloy steel. At the same time, after many years, when the actual effect of sealing is weakened by damage, you can tighten the flange again, improve the sealing characteristics, loosen the foot bolt, remove the pressure ring, put in a layer or double sealing ring, snap the pressure ring, and use again. The chloride ion content is not specified, and is especially suitable for systems where the chloride ion content of the substance or the surrounding environment is not acceptable.
