Made of a synthetic material that is rigid but presents no risk of sleeve damage due to frictionn it acts as the support surface for the sealing rings. The self-lubricating nature of the material allows for fine adjustment of the shaft clearance. The inner diameter of the packing ring has a helical groove intended to direct, orientate, and uniformly distribute the gas flow injected via the lantern ring. The purpose of this flow is to prevent solid particles migrating into the sealing rings, and especially between the sleeve and the inner diameter of the rings. Braids Separators Provide a complete seal between the lantern ring and the atmosphere. In this way, they ensure the preferred direction of the gas flow towards the tank. Optimizes the transmission of axial tightening across the whole length of the cartridge seal. In this way, the resultant radial force, a factor in sealing, is made homogeneous and effective across the entire length of the seals. The tightening needed to realize sealing is minimized, thus limiting the friction load and minimizing heating and wear. A metal part of which the shape and fit are designed to allow the injection of a gas, to direct and distribute it evenly around the sleeve. Dynamic clamping assembly Sleeve Gauge Braids Provide the seal between the lantern ring and the mixer tank. It provides a directional seal. The structure and material of the braided ring and the dimensional characteristics of the rings, combined with gas injection via the lantern ring, lead to the creation of an annular gas flow towards the tank, which prevents any migration of particles into the seals. Lantern ring HEAT STERILIZERS Biomass from slaughtering cycles from 0 to 00 C = 0 to bar Shaft = Ø 0 mn Rotation speed = to 0 RPM The size, number, mounting sequence, and height after tightening of the stack allows the setting of the correct pre-load on the sealing rings ensuring sealing while controlling friction. The flexibility of the spring washers allows the maintenance of this pre-load, within known limits, as the sealing rings become compressed. Interchangeable component intended to protect the shaft from abrasive wear, and allowing the integration of a bearing surface with optimum characteristics in terms of surface finish and hardness (chromium carbide). Visible indication of tightness and wear on the sealing rings. Indicates the need for a preventive retightening and simplifies operator action by limiting, with a stop, the force transmitted to the seals. Visual retightening. Retention and anti-shock screw To be removed before installation. Allows for long storage without stressing the active components.
