TRICKLE IMPREGNATING MACHINE

TRICKLEIMPREGNATING MACHINE (BATCH TYPE)According to the principle of Trickle Impregnation, activated resin is trickled in a thin jet on to therotating preheated winding. The resin immediately gets heated and its viscosity is reduced. Due to therotary motion of the winding, the resin gets distributed evenly inside the winding without any drain loss.The heated winding accelerates the gelling and curing of the resin. The resin applied on the winding isquickly sucked through the slots. Assisted by the capillary action it pushes out the trapped air from thesmall voids and gaps, in the winding and penetrates evenly in all the voids. The essential point forsuccessful application of the trickle impregnating resin is the correct adjustment and the control of thewinding temperature.TRICKLEIMPREGNATING MACHINESThe design of a Trickle Impregnation Plant ensures the uniform quality of a trickle impregnation. Our trickle impregnation plants have the following essential features. Automated Cycle, independent of operator.Arrangement for quick mounting and for making the connections of resistanceheating.Precise temperature control of the winding.Accurately metered resin quantity required for the component.The trickle impregnation plants with the above features are custom built taking into account several factors such as production rate, size and shape of the component, type of trickle resin etc. The trickle impregnation plants are suitable for carrying complete Trickle Impregnation process i.e. Pre-heating, Trickling and Curing. The Plants are completely automatic except for job loading and unloading. Mainly three types of trickle impregnation plants are popular for various types of components.Trickle impregnation process is especially characterized by its low energy cost due to a very short cycle time compared to Dip Varnishing or the Vacuum impregnation. Compared to the Dip and bake varnishing method, which uses varnishes containing 50 to 55% solvents and the impregnation cycle of 8 hrs to 24 hrs. Trickle impregnation cycle times are substantially low to the tune of 20 min. to 40 min. Hence it is quite evident that trickle impregnation process offers the most cost economical answer to the impregnation process.
