Definitions
- the invention relates to a sealing head for feeding a Heat transfer medium, esp. Of a heat transfer oil, to a rotating printing system, such as a drying drum, Heating roller or the like.
- a sealing head for feeding a Heat transfer medium, esp. Of a heat transfer oil, to a rotating printing system, such as a drying drum, Heating roller or the like.
- a Heat transfer medium esp. Of a heat transfer oil
- a rotating printing system such as a drying drum, Heating roller or the like.
- a sealing head for feeding a Heat transfer medium, esp. Of a heat transfer oil
- a rotating printing system such as a drying drum, Heating roller or the like.
- Such a sealing head is for example from the EP 0 448 730 and has been in practice extremely well proven. Note, however, that this Solution an increased effort because of the circulation of a Master medium required.
- the invention is based, by constructive development of a sealing head of to improve the type mentioned above so that at Simplified structure and operation at Maximum temperature of the heat transfer medium is made possible without any increased wear, especially in the Sealing area occurs.
- the advantage achieved by the invention consists in essential in that, despite reduced expenses, like the implementation of simple cooling measures as well as the Attaching a simple insulating a safer Operation at maximum temperature of the heat transfer medium becomes possible without any downtime problems on the seal occur.
- Cooling flange an annular cooling chamber for a having flowing through cooling medium.
- the cooling chamber each with a diametrical is provided to each other arranged inlet and outlet. This is a complete separation of this Cooling circuit ensures, so that the cooling optionally with lubricating oil or just with cooling water can be done.
- a sealing chamber forming a closed chamber is arranged, wherein in the chamber a filling nozzle for a preferably liquid medium opens.
- This chamber can with a suitable liquid without pressure over the Filling nozzles are filled, creating a chemical Reaction between the atmospheric oxygen and the over the Mechanical seal is prevented from exceeding oil leakage.
- the illustrated in the drawing sealing head 1 is used for Supplying a heat transfer medium, in particular a Heat transfer oil, to a rotating printing system 2,
- a heat transfer medium in particular a Heat transfer oil
- a rotating printing system 2 For example, a drying drum, heat roller or like that in the drawing only with his Connection device is indicated.
- the Sealing head 1 from a connected to the printing system 2 tubular rotor 3 and one on two bearings 4 the rotor 3 arranged stationary Sealing head housing 5, which has a connecting piece 6 for a the heat transfer medium leading, not in the drawing own connection cable has shown.
- Inside the Sealing head housing 5 is the rotor 3 at the open end of the pipe via openings 7 in direct connection with the Connecting piece 6, so that the heat transfer medium through the Connecting piece 6 and the rotor 3 in the printing system can get.
- connection piece 6 and the rolling bearings 4 a mechanical seal 8 is arranged, the rotor 3 against the wall of the sealing head housing. 5 seals.
- This mechanical seal 8 is preferably from a via a bellows 9 attached to the rotor 3 Sealing ring 10 and one on the seal head housing. 5 fixedly arranged sealing ring 11th
- the mechanical seal 8 is of an am Sealing head housing 5 arranged cooling flange 12th enclosed, the axially on both sides of the Mechanical seal 8 extends.
- the insulating member 14 is in detail as on Sealing head housing 5 fixed sleeve part designed, wherein the connecting piece 6 facing side as radially projecting inner flange is formed.
- the inner lateral surface of this inner flange forms the Limitation of the annular gap 13 to the rotor 3 out.
- the axial Height of this inner flange affects the width of the Annular gap 13, reducing the circulation of Heat transfer medium between the outer area of Mechanical seal 8 and the area flowed through on Connecting piece 6 and the openings 7 largely prevented and thus the temperature of the Heat transfer medium in the sealing area significantly reduced becomes.
- the insulating member 14 is supported axially against the cooling flange 12, so that, since the Insulating element 14 expediently made of a material low thermal conductivity exists, a continuous heat-insulating effect up to the cooling flange 12 is reached.
- the cooling flange 12 has, as can be seen in particular from 2 shows, an annular cooling chamber 15, which is flowed through by a cooling medium.
- This is the Cooling chamber 15, each with a diametrical to each other arranged inlet and outlet 16,17 provided.
- Cooling medium can a variety of suitable Liquids are used because of this cooling circuit self-contained, so no touch For example, can occur with the heat transfer medium. In particular, this is lubricating oil or simple Cooling water are used.
- This thus formed chamber 18 can via a filling nozzle 20 with a preferably liquid medium are filled, thereby preventing that a chemical reaction of the over Mechanical seal 8 in this chamber 18 reaching Oil leakage can occur with atmospheric oxygen.
- the rotor 3 is in which via the mechanical seal. 8 or the sealing element 19 and the bearings 4 extending, provided with the reference numeral 21 area designed double-walled, thereby complementing the Heat transport from the rotor 3 forth to the mechanical seal. 8 is reduced.
