Background
The continuous vulcanization production line is a high-efficiency production mode which combines an extrusion process and a vulcanization process into a whole, and is mainly used for producing rubber sleeve cables.
The continuous vulcanization production line is divided into a horizontal type, an inclined type, a catenary type and other structures according to the arrangement structure form of the vulcanization pipelines. The catenary type vulcanization pipeline is a good choice for the surface quality of the produced cable and the service life of the pipeline.
Based on the catenary curve type arrangement structure of the catenary type vulcanization pipeline, the tail end of the cooling pipe at the downstream needs to bear a large force, and the most obvious stressed component is a sealing ring which is arranged at the tail end of the cooling pipe, is used for sealing and blocking water and guiding a cable to pass through.
The sealing ring at the tail end of the cooling water pipe of the existing catenary type vulcanization pipeline is of a PE (polyethylene) structure (see figure 1, the center of the sealing ring is provided with a threading hole 4 with a through hole structure), although the sealing ring can resist most of acid and alkali erosion at normal temperature, the mechanical property and the wear resistance are lower, and the lower mechanical property mainly shows two aspects of lower tensile strength and poorer creep resistance. However, under the dual actions of the take-up tension and the self gravity, the rubber sleeve cable produced by the continuous vulcanization of the catenary vulcanization pipeline enables the sealing ring at the tail end of the cooling water pipe to bear larger longitudinal pressure and transverse pressure, so that the sealing ring is easily damaged and cracked to be damaged; in addition, based on the continuous vulcanization characteristic of the rubber sleeve cable, all component materials contained in the rubber sleeve material are easily mixed into cooling water and form precipitation and collection at a sealing ring at the tail end of the cooling water pipe, in the drainage process of the cooling water along with the take-up action of the rubber sleeve cable, the impurity materials can cause erosion abrasion to the sealing ring flowing through, the erosion abrasion is more obvious under the condition of higher temperature, the higher temperature is from the high-temperature rubber sleeve cable, so that the temperature change amplitude of the cooling water in the cooling water pipe is larger and the instantaneous temperature is higher (generally about 40 ℃), and further the damage of the sealing ring at the tail end of the cooling water pipe is aggravated.
In summary, based on the structural arrangement of the catenary type vulcanization pipelines and the particularity of the production process, the technical problems of short service life, high maintenance and replacement frequency and the like exist in the PE structure sealing ring at the tail end of the cooling water pipe of the existing catenary type vulcanization pipeline due to the lower mechanical property and wear resistance, so that the normal operation of the catenary type vulcanization pipeline is seriously influenced, and the improvement is necessary.
