Definitions
- the invention relates to a device for pumping large quantities of liquid, with at least two pumps each forming its own structural unit, which are connected on the pressure side together to a pressure line and coupled to a common drive.
- Pumps of this type are used for testing and cleaning pipelines. To test the pipelines, they are checked for leaks by "stressing". In this case, a liquid, for example water, is pumped into the pipelines under a pressure which is higher than the medium to be conveyed in the pipeline in the pipeline's operating state. If the pipeline tested in this way is leakproof at a higher test pressure, it is assumed that it is also leakproof in the operating state, at a pressure lower than the test pressure.
- stressing In this case, a liquid, for example water, is pumped into the pipelines under a pressure which is higher than the medium to be conveyed in the pipeline in the pipeline's operating state. If the pipeline tested in this way is leakproof at a higher test pressure, it is assumed that it is also leakproof in the operating state, at a pressure lower than the test pressure.
- the length of the section that can be checked during a stress event depends on the amount of liquid that can be introduced into the pipeline. The greater the amount of liquid that can be pumped into the pipeline at the desired pressure, the greater the length of the section that can be checked. The greater the length of the individual sections, the lower the number of stress Operations required to review a given pipeline section and the less effort required to review that pipeline section.
- a device is known from practice in which a plurality of pumps, each forming a structural unit, are connected together on the pressure side to a pressure line. This results in a large total delivery rate of the device in the sum of the individual delivery rates of the individual pumps.
- the known device consists of three modules, a drive unit, a first pump unit and a second pump unit.
- the individual pumps of the known device are driven by the common drive.
- a transfer case is connected to the drive, to which the drive shafts of the pumps are coupled.
- Two pumps are arranged on a common drive shaft in the first pump unit, while only one pump is provided in the second pump unit.
- this device is unwieldy due to the large number of modules and the space required.
- the stressing of pipelines takes place on site at the individual construction stages of the pipeline. For this purpose, the device must be transported to the individual construction sections of the pipeline. In the known device, this is done by disassembling the device into its individual modules and transporting it to the place of use in modules.
- the object of the invention is to develop the known device described in more detail above in such a way that an easy-to-transport and space-saving device is created.
- a device of the type specified at the outset at least one of the pumps is positioned in a plane which is vertically spaced from the plane in which the respective other pump is arranged.
- the vertically spaced arrangement makes it possible to stack the individual pumps directly one above the other, thereby saving considerable space.
- the invention makes it possible to combine the individual units of the device into modules. These can be easily transported to the respective place of use and in turn can be set up to save space.
- the drive power of the common drive is preferably divided by a transfer case to the drive shafts of the individual pumps. It is expedient if a transfer case is assigned to each level, via which the pumps assigned to this level are coupled to one another on the drive side are and the transfer case are additionally coupled to each other so that the pumps can be connected to the common drive via one of the transfer case.
- the levels can run parallel to one another and the transfer case assigned to one level can be coupled to the transfer case of the other level via a shaft running perpendicular to the respective level.
- a preferred embodiment of the invention has three pumps, two of which are arranged in one plane and the third is positioned in the plane spaced vertically from it.
- the device is particularly easy to transport if its individual parts are accommodated in a housing, the dimensions of which correspond to the dimensions of a standard container, for example an ISO 20 '' container.
- a device of the type according to the invention that is optimized with regard to the lowest possible pulsation is characterized in that the pumps are coupled to the drive in such a way that each of them executes a pumping stroke offset from the other pumps by a certain, fixed time interval.
- the pump strokes of the individual pumps are coordinated with one another in such a way that pulsation in the pressure line is largely avoided.
- Devices of this type designed in accordance with the invention no longer require a pulsation damper and, because of the low pulsation achieved and the structure distributed over several vertical planes, are
- the device according to the invention is easy to disassemble and transport, particularly suitable as devices for stressing pipelines.
- This embodiment of the invention can be implemented in a simple manner in that the pumps are coupled to the drive via a crankshaft, the crank pins being arranged evenly distributed around the axis of rotation of the crankshaft.
- FIG. 2 is a sectional view taken along the line I-I in Fig. 1,
- Fig. 3 is a sectional view along the line II-II in Fig. 2 and
- FIG. 4 shows a sectional view along the line III-III in FIG. 2.
- the module 1 shows a side view of the device according to the invention, which forms a single module 1.
- the module 1 is formed by a frame 2, the dimensions of which correspond to those of a standard container.
- the drive unit 3 and the pumps 4, 5, 6 are arranged in the frame 2.
- the pump 4 is placed on a level above the pumps 5, 6.
- Pressure lines 13, 14, 15 are arranged on the pressure side of the pumps 4, 5, 6 and are brought together in a pressure control valve 16.
- An outlet connection 17 is provided on the pressure regulating valve 16.
- a transfer case 18 is connected to the drive unit 3, which can be designed as an internal combustion engine, for example, in the level of the pumps 5, 6.
- a second transfer case 22 is connected to the transfer case 18 via a vertical shaft and lies in the same horizontal plane as the pump 4.
- the pump 4 is connected to this transfer case 22 via a drive shaft 23 by means of a clutch 24.
- the illustrated device according to the invention is operated as follows:
- the drive 3 delivers its drive line to the transfer case 18, from which it is passed on to the drive shaft 21 and to the second transfer case 22.
- the pumps 5, 6 are driven by the drive shaft 21, while the pump 4 is driven by the drive shaft 23 continuing from the transfer case 22.
- This distribution cylinder 9 is fed by liquid which flows through the inlet port 7 and the filter 8 connected to it.
- the liquid is pumped into the pressure lines 13, 14, 15 by the pumps 4, 5, 6.
- the device described creates a compact device for pumping large amounts of liquid which is easy to transport due to its small dimensions.
