Definitions

  • the innovation relates to a compressor unit enclosed by a housing, with a drive motor, a screw compressor and a fan wheel as well as additional units.
  • the innovation is based on the task of designing a compact and economically designed compressor unit with low noise emission for a diesel-driven screw compressor.
  • the fan wheel is arranged between a diesel engine and the screw compressor, with a cooling air inlet being formed on one end face of the housing and for the air sucked in by this one passing over the fan wheel upwards and into a horizontal section Channel is provided, which is followed by a section running again upwards and parallel to the aforementioned horizontal section in the opposite direction, which is arranged outside the housing on its upper side.
  • the central fan arrangement with the exhaust air duct lying above it results in a compact construction of the compressor unit, which permits a favorable arrangement of the other additional units with economical cooling air guidance.
  • the multiple deflection of the exhaust air above the central fan wheel results in effective noise reduction.
  • the free end face of the diesel engine is expediently provided for driving the hydraulic device, so that both sides of the diesel engine are used for drive purposes.
  • the diesel engine can be an air-cooled engine, wherein on the side of the drive for the hydraulic device there is another motor-internal fan wheel, which draws in the cooling air required for the engine from the front side of the housing, which leads to the cooling air inlet for the oil cooler of the. Compressor is opposite.
  • the cooling air for the motor can be sucked in directly from the front side or also from below on the front side, the latter embodiment in turn resulting in better sound absorption.
  • An easily releasable coupling is advantageously provided between the central fan wheel and the diesel engine, so that the diesel engine can drive the hydraulic device alone if this is necessary.
  • a diesel engine 2 is arranged in one half of the housing in the view according to FIGS. 1 and 2, which on the inner side via a not shown, easily releasable coupling with an approximately in the The center of the housing 1 arranged fan wheel 3 is connected, of which only the hood 4 surrounding the fan wheel is shown in FIGS. 1 and 2.
  • An i screw compressor 5 is arranged in the other half of the housing 1 on the opposite side of the fan wheel.
  • a cooling air inlet 6 is formed on the front side.
  • a cylindrical oil container 7 is arranged in a vertical position behind the cooling air inlet and contains the oil reservoir required for the screw compressor 5 working with oil injection and is provided with an oil separator.
  • an oil cooler 8 is arranged behind the oil container 7 and extends almost over the entire cross section of the interior of the housing 1.
  • a cylindrical air filter 9 for the air drawn in by the screw compressor is arranged above the screw compressor 5, a pipe socket 10 being guided past the oil cooler 8 by the air filter 9 and opening into the space in front of the oil cooler 8, as is the case this is shown in Fig. 2.
  • the compressor sucks in cold air and not the air which has already been heated by the oil cooler 8.
  • another air filter 11 is located laterally above the screw compressor 5 and behind the _ Oil cooler 8 arranged, which filters the combustion air for the diesel engine 2.
  • a line section 12 is also provided on this air filter 11, which leads past the oil cooler 8 into the space in front of it, so that cool air is sucked into the combustion chambers of the diesel engine 2 and thus more air per unit volume.
  • the cooling air sucked in by the central fan wheel 3 through the cooling air inlet 6 flows upward approximately vertically above the fan wheel 3 and is then passed into an approximately horizontal channel section 13 (FIG. 1) which extends counter to the direction of flow of the sucked-in cooling air and then through a Opening in the top of the housing 1 is deflected upwards.
  • a further channel section 14 is arranged above this opening on the upper side of the housing 1 and runs approximately parallel to section 13 and in the opposite direction.
  • the outlet opening 15 of the exhaust air duct 13, 14 lies with its plane perpendicular to the longitudinal axis of the housing and is directed towards the side opposite the suction side at 6, so that the warm exhaust air cannot get into the cooling air inlet.
  • two exhaust ports 16 of the diesel engine 2 protrude on the upper side of the housing, which are curved in the direction of the exhaust air, as shown in FIG. 1.
  • a drive unit 17 for the hydraulic device is arranged on the left-hand side of the diesel engine 2 shown in FIGS. 1 and 2.
  • a fan wheel 18 (FIG. 2) is arranged on this side, which ensures the cooling air required by the air-cooled diesel engine 2.
  • this is sucked in on the left end face of the housing 1 through an inlet opening 19 arranged on the underside of the housing.
  • This suction opening can also be formed in the left end face of the housing 1.
  • a partition wall can be provided on the left side of the hood 4 of the fan wheel 3 in FIGS. 1 and 2, which extends upwards and the cooling air flow sucked in from the right side deflected above, while on the other side of this partition wall, not shown in detail, the cooling air flow drawn in from the left-hand side is directed upward and conducted into the exhaust air duct 13, 14.
  • a cutout 20 indicated by dashed lines in FIG. 2 can be provided on the upper side of the fan cover 4, through which the cooling air drawn in from the right end face is directed upward.
  • the housing 1 shown in cross section in FIG. 3 can be lined with a sound-absorbing insulating material 21. At 22 handles are shown, which are attached to removable side parts of the housing 1. As shown in FIG. 3, the exhaust air opening 15 extends over the entire width of the housing 1.
  • the cylindrical fan cover 4 is held by struts 23 which are fastened to a flange of the screw compressor 5.
  • the housing 1 is placed on vibration-damping rubber bearings 24 on a frame 25 made of I-beams. This frame 25 can be arranged stationary or on a chassis.
  • an oil container 26 which contains the lubricating oil required by the diesel engine 2.
  • the diesel has engine 2 no oil pan, rather the oil reservoir usually contained in the oil pan is contained in the container 26.
  • a water-cooled diesel engine or possibly also a gasoline engine can be provided, the water cooler of the engine being arranged on the side of the fan wheel 18 or the drive 17 for the hydraulic device and the cooling air inlet likewise being arranged on the left side of the housing becomes.
  • the fan wheel 3 is designed so that it generates the required pressure against the cooling air flow built up by the fan wheel 18 of the motor.
  • the cross section of the exhaust air duct is designed so large that there is no mutual hindrance or a jam between the two cooling air streams which meet.
  • the opening cross section of the channel section 13, like the outlet opening 15, extends over the entire width of the housing 1.
  • a radial fan can also be arranged between the diesel engine and the screw compressor.
  • a spiral housing is expediently arranged between the compressor and the motor, which directs the exhaust air flow upwards.
