摘要： So-called decoking, in other words, the emptying of a container (23), in which coke arising from the operation of a refinery is deposited is carried out using a decoking tool (24) with a free mounting on the end of a drilling bar (3). The mounting is achieved using a sliding guide (4) on a guide plate (1), coupled to the container (23). According to the invention, distortions in the container and the guide plate (1) therewith as a result of temperature variations during operation of the refinery which could lead to function disturbance of the drilling rod (3) are avoided, wherein the sliding guide (4) and the guide plate (1) are arranged with a sprung relative deflection by means of at least one spring element (5) in the manner of a spring damper.

摘要： The invention relates to a tool for breaking up coke, comprising a housing which is fixed to a drilling rod in the operating state and in or on which at least one jet for cutting and one jet for drilling of coke is arranged and at least one valve for opening and closing the jets. The tool is embodied for two different operating states. The at least one valve closes the cutting nozzle in the drilling operating state, whilst in the cutting operating state the drilling nozzles are closed by the at least one valve. The housing, valve and nozzles are embodied such that an unhindered flow of water from the drilling rod through the housing and the valve and the nozzles which are not sealed by the valve is guaranteed, characterised in that the nozzles for sealing, depending on the selected operating condition, are sealed by the balls of a ball valve. The invention further relates to a tool in which the arrangement for operating the valve is arranged above the nozzles.

摘要： The invention relates to a tool for comminuting coke comprising a housing which, during operation, is fastened to a boring rod. At least one cutting nozzle for cutting, a boring nozzle for boring coke, and at least one valve for controlling a direction of flow of the water flowing through the boring rod and the housing, through the cutting nozzle and the boring nozzle are arranged on or inside said housing. In order to provide a tool for comminuting coke that has a simple design and can be reliably used and maintained, the invention provides that at least two flow channels are made inside the housing that each extend between individual inflow openings, which are assigned to the respective flow channel, and the cutting nozzle and the boring nozzle. The valve for closing and opening the inflow openings is placed in the area of the inflow openings.

摘要： The invention relates to a magnetic coupling, in particular a magnetic coupling pump, which comprises an inner rotor and an outer rotor between which a separating can (1) is arranged, which has a flange (2). Said flange (2) can be fastened to a coupling component (6), preferably to a housing cover (6), by means of a mating flange (7). The separating can (1) is made of a ceramic, wherein the coupling component (6) and the mating flange (7) are made of a metallic material. Harmful stress transitions or stress peaks in the preloading of the connection and thermal material expansions can cause damage to the separating can, in particular to the flange of said separating can, or can cause relaxations that can lead to leaks. Therefore, according to the invention, a spherical elevation (13) is arranged on the flange (2), which spherical elevation engages in a corresponding spherical recess (14). Also according to the invention, a compensating element (17) is arranged between the flange (2) and the mating flange (7). The compensating element (17) can have a spherical recess (14) on one of the end faces (18, 19) of the compensating element, said spherical recess corresponding to the spherical elevation (13).
