Definitions
- the invention relates to a multi-stage compressor for compressing gases having a low-pressure region and a high-pressure region, wherein at least one rotary compressor and in the high-pressure region at least a two-cylinder reciprocating compressor is provided and a common motor for driving the rotary compressor and the reciprocating compressor is provided.
- a rotary compressor in particular a screw compressor
- a reciprocating compressor in the high pressure region is basically known from WO 03/010436 A1.
- a multi-stage reciprocating compressor is shown for high compression of the gas to be compressed, wherein the cylinders of the individual compressor stages are arranged in a V-shape to each other.
- the drive of the reciprocating compressor and the low-pressure compressor takes place here via a common crankshaft.
- DE 199 32 433 A1 discloses a method for improving the economy of positive-displacement compressors, wherein it is disclosed herein that a centrifugal compressor is driven either by the drive motor of a reciprocating compressor or by a separate motor.
- a multi-stage piston compressor for the production of compressed air for rail vehicles which consists essentially of a drive unit and a downstream compressor unit and has a low-pressure and at least one high-pressure stage.
- Each of the cranks lying on a crankshaft has two opposing pistons mounted thereon, with adjacent cranks being arranged essentially offset by 180 ° with respect to one another, the pistons in this case being able to be vertically standing, horizontally lying or V-shaped.
- a reciprocating compressor system which has a boxer compressor, are rotated in the piston liners of a staged cylinder by 180 ° and arranged opposite one another.
- the pump or compressor unit has a crankshaft with three cranks, wherein two adjacent cranks are offset by 180 ° to each other, whose respective cylinders are arranged opposite each other in a horizontal plane.
- the aim of the present invention is now to provide a multi-stage compressor of the type mentioned, which compared to comparable multi-stage compressors has an improved vibration behavior.
- this is achieved in that the cylinders are arranged rotated in the high pressure region by 180 ° to each other. Due to the 180 ° twisted, opposite arrangement of the cylinder results in a much lower vibration run recorded in the cylinders piston for compression of the gas to be compressed. Together with the rotary compressor provided in the low-pressure range, this results in an extremely compact multi-stage compressor, with which a relatively high compression of a gas to be compressed can be achieved, whereby at the same time the pressure generated by the multi-stage compressor. th vibrations are kept low. As a result, the multistage compressor according to the invention is particularly suitable for use in mobile compressor installations as well as in compressor installations mounted on a ship.
- the reciprocating compressor whose at least two cylinders are arranged rotated by 180 ° to each other, that are arranged in a so-called box design, compared to conventional, for example, V-shaped arranged to each other, cylinders have relatively low center of gravity.
- the engine is arranged laterally next to the reciprocating compressor.
- it is favorable for a flat and thus a low center of gravity training when the longitudinal axis of a crankshaft of the engine as well as the longitudinal axis of the cylinder are arranged substantially horizontally.
- the rotary compressor is coupled to the engine driven reciprocating compressor. In this case, only a single crankshaft is required, over which both the rotary compressor and the reciprocating compressor are driven.
- the multi-stage compressor according to the invention should also be suitable in particular for mobile use on ships and trucks, it is favorable if the multi-stage compressor has a comparatively small span or width, without reducing the efficiency. This is advantageously achieved in that in each case a stepped piston is received in the cylinders. Alternatively, achieving a small span is also possible when the cylinders are double acting are formed. Due to the comparatively short span, the multi-stage compressor can advantageously be accommodated in ISO containers that are 8 ft (2.54 m) wide and either 20 ft (6,079 m) or 40 ft (12.9 m) long.
- Previously known multi-stage compressor which had both a rotary and a reciprocating compressor, in which the piston compressor but V-shaped were arranged to each other, however, could not be included in ISO containers, which made a mobile application considerably more difficult.
- At least one control device is provided between the individual compressor stages, wherein as a control device discharge valves, bypass valves, adjustable dead spaces, speed controller and other fittings can be provided.
- various mechanical, pneumatic, hydraulic, electrical or electronic components can be used to control or regulate the multi-stage compressor, whereby both a local control and a remote operation is possible.
- the "individual" compressor stages can be assigned to both the low-pressure region and the high-pressure region, or else both can be assigned to the high-pressure region.
- Fig. 1 shows schematically a perspective view of a multi-stage compressor in which a rotary compressor and a reciprocating compressor in boxer design are arranged on opposite output sides of a central drive motor;
- Fig. 2 shows schematically a perspective view of a further embodiment in which the rotary compressor is coupled to the crankshaft of the box-type piston compressor;
- FIG. 3 shows schematically a block diagram of a multi-stage compressor with a two-stage high-pressure compressor
- FIG. 4 schematically shows a sectional view of a further embodiment with a box-type two-stage reciprocating compressor
- Fig. 5 shows schematically a sectional view of a cylinder with a stepped piston
- Fig. 6 shows schematically a sectional view of a double-acting cylinder.
- a multi-stage compressor 1 is shown, wherein in a low-pressure region 2, a screw compressor 3 is provided.
- the screw compressor 3 is coupled to a central drive motor, which drives the piston compressor 6, which is likewise provided in the high-pressure region 5, via a further crankshaft.
- the reciprocating compressor 6 in this case has two cylinders 7, which are arranged rotated by 180 ° to each other, so that the reciprocating compressor 6 is designed in a so-called boxer design, in which the piston 7 'accommodated in the cylinders 7 (see FIG. in the same plane of movement.
- Fig. 2 an alternative embodiment is shown, in which case the drive motor 4 only has a crankshaft 8, which drives with the interposition of a flywheel 9 via a coupling 10 in the boxer design running reciprocating compressor 6.
- the screw compressor 3 provided in the low-pressure region 2 can then be driven via the same crankshaft.
- FIGS. 1 and 2 also show that the screw compressor provided in the low-pressure region 2 is conventionally associated with an inlet control valve 11, via which the air inlet is regulated and the air inlet is closed in the event of the multistage compressor 1 being lowered.
- air filter 12 of the drive motor 4 can be seen, as well as oil filter 13 and fuel filter 14.
- a pulsation damper 17 is provided to limit the pressure oscillations of the gas to be compressed.
- the already pre-compressed gas enters the high-pressure region 5, in which a multi-stage piston compressor 6 is provided, in which in each compressor stage 6, 6 1st two opposite cylinder 7 and piston 7 'are provided so that apart from the compact design of the multi-stage compressor 1 and the high efficiency of the compression and a high degree of smoothness of the overall arrangement is ensured, whereby the multi-stage compressor 1 in particular for use in mobile compressor systems and suitable on ships.
- a further embodiment of the multi-stage compressor 1 is shown, in which in particular the centrally located common engine 4 can be seen, which has a crankshaft 8 with two stub shafts 8 1 , wherein a shaft stub 8 'in the low pressure region 2, a screw compressor is driven and over the other stub shaft 8 'of the two-stage reciprocating compressor. 6
- the two compressor stages 6, 6 'of the reciprocating compressor 6 designed in box construction can hereby be designed, as can be seen in FIGS. 5 and 6, as a stepped piston 15 or as a double-acting cylinder 16.
- a comparatively short design of the reciprocating compressor 6 can be achieved and thus provided in accordance with the invention, rotated by 180 ° to each other arranged arrangement of the cylinder 7 in the high pressure region 5, a comparatively smaller span of the entire device 1 can be achieved since the reciprocating compressor 6 in the Width has the largest extension of the entire device 1.
- the installation of the multi-stage compressor 1 in ISO containers which have a width of 8 ft (2.44 m), possible, which for mobile use, especially on ships, together with the low center of gravity of the overall device of great advantage.
