The invention relates to a process for connecting a pipe ( ) in the region of its pipe end to a pipe coupling ( ), comprising at least one support sleeve ( ) with engagement elements ( ), in which context the pipe ( ) and the support sleeve ( ) are first pushed into one another, the pipe ( ) then being pressure deformed, thereby bringing about a form-fitting connection with the engagement elements ( ) and bringing about a sealing relationship with sealing surfaces ( ), mutually adjoining each other in axial direction. The process is characterised in that an axial force, bearing on the sealing surfaces ( ) is applied to the pipe ( ) by way of a spring device ( ) deriving support from the pipe coupling ( ) and that a facility for expansion is provided for the pipe ( ) on the side of the engagement elements ( ) oriented towards the pipe.

Method for connecting a pipe and a pipe coupling, link between a pipe and a pipe coupling, and connector used

A pressing device includes a pressing tool, an electric motor for driving the tool, and a rechargeable battery for supplying energy to the electric motor. A control device has a voltage comparison element that performs a voltage comparison between the battery voltage and a limit voltage. The control device generates an attention signal and/or limits activation of the electric motor if the voltage comparison element indicates that the battery voltage is equal to or less than the limit voltage. The control device includes an interval element with at least one storable interval. A load element acts upon the battery so that it generates a varying voltage curve. The interval element is activated when the load element is on and voltage comparison is made during a predetermined interval.

Handleable working device, in particular pressing device

A pressing device for joining workpieces has a pressing tool and a motorized drive for actuation of the pressing tool over a pressing distance, as well as a control device which has a drive control device for influencing the drive. The drive control device has a malfunction detection device which has an actual value sensor which is suitable for detecting, as the actual value, a physical magnitude which is correlated with the pressing resistance. At least one limit value profile for the actual value is retained in the malfunction detection device, and it has a comparison device which, during a pressing, checks whether the particular actual value lies on the permissible or impermissible side of the pertinent limit value profile. The malfunction detection device comprises a signal device and/or a shutdown device for the drive, which are/is activated if the actual value lies on the impermissible side of the pertinent limit value.

Pressing device

Press apparatus

A tube-type heat exchanger having inlet and output conduits and tubes connected therebetween, and a return conduit extending from the output to the inlet conduit is, as is known, traversed by a coolant liquid from the intake to the output conduit through the tubes. Balls are released into the intake conduit from the return conduit and pass with the coolant through the tubes to clean same. These balls are trapped in the output conduit and introduced back into the return conduit where each ball's momentum is measured and outputs corresponding thereto are generated. These outputs are compared with a set-point signal corresponding to minimum acceptable ball momentum and all of the balls from the conduits are withdrawn and replaced with fresh balls when in a predetermined period of time a predetermined number of the outputs fall below the set-point signal.

Batch-type scrubbing-ball replacement system for heat exchanger

A tube-type heat exchanger having inlet and output conduits and tubes connected therebetween, and a return conduit extending from the output to the inlet conduit is traversed by a coolant liquid from the intake to the output conduit through the tubes. Balls are released into the intake conduit from the return conduit and pass with the coolant through the tubes to clean same. These balls are trapped in the output conduit and introduced back into the return conduit where each ball's momentum is measured and an output corresponding thereto is generated. This output is compared with a set-point signal corresponding to minimum acceptable ball momentum, and any ball whose momentum is below the minimum momentum is withdrawn from the return conduit and replaced in the conduits with a fresh ball.
