Definitions
- the present invention relates to a pumping station for a pipeline, in particular oil or gas pipeline having the features of the preamble of claim 1, and a method for starting at least one internal combustion engine in such a pumping station.
- Pumping station includes compressor stations.
- Pumping stations for oil or gas pipelines use internal combustion engines, such as large gas engines, which drive one or more feed pumps to convey the medium - oil or gas - through the pipeline.
- Such gas engines have for example a power of 1800 to 1 1000 hp and a starting torque of, for example, 32000 Nm at 4000 hp.
- the ignition speed may then be 65 rpm, for example, and should be held for 30 seconds.
- the pumped medium in particular gas
- the internal combustion engine is used to start the internal combustion engine. For environmental reasons, this is no longer desirable.
- a hydraulic pressure accumulator is filled by means of a filling pump.
- the hydraulic medium contained in the hydraulic pressure accumulator which can be designed as a bladder accumulator, as a piston accumulator or as a spring accumulator, is then switched electrically or by manual actuation of a valve to a hydraulic motor, which raises the internal combustion engine to an undefined speed so that it can ignite.
- a toothing between the hydraulic motor and the internal combustion engine must be meshed.
- Einspuren by an auxiliary power such as electrical, hydraulic or pneumatic displacement of a gear of the hydraulic motor in a drive connection with the engine

- the starting of the internal combustion engine that is, the pulling up of the crankshaft of the internal combustion engine with the hydraulic motor, has hitherto been characterized in that the pressure prevailing in the accumulator pressure is transmitted unregulated by the hydraulic medium to the hydraulic motor, so that the internal combustion engine is ignited at an undefined speed. As a rule, this achieves a speed level which is higher than required.
- the internal combustion engine can be safely ignited, however, the energy consumption from the hydraulic pressure accumulator is high, so that comparatively large and therefore expensive hydraulic storage must be provided.
- the present invention has for its object to provide a pumping station for a pipeline of the type shown above, which manages with a smaller, less expensive hydraulic pressure accumulator. Furthermore, a method for starting a corresponding internal combustion engine in a pumping station should be specified, which enables the use of the comparatively smaller hydraulic pressure accumulator.

- a synchronized or unsynchronized coupling between the hydraulic motor and the internal combustion engine may be provided.

- the pressure accumulator is designed as a memory with gas tensioning device, in particular as bladder or diaphragm accumulator.
- an additional gas storage gas-conducting connected to a gas side of the accumulator to increase the gas spring of the pressure accumulator. For example, at constant pressure level and at the same maximum storage pressure by connecting an additional gas storage, which may be filled with nitrogen, for example, doubles the maximum recordable amount of hydraulic medium, especially if the gas storage has at least the same receiving volume as the pressure accumulator.

This list is not exhaustive, but other sizes can be used. Of course, it is also possible to determine the speed of the internal combustion engine based on state variables outside the hydrostatic system or to measure directly.
