Definitions

  • the present invention relates to a screw compressor for a utility vehicle.
  • Screw compressors for commercial vehicles are already known from the prior art. Such screw compressors are used to provide the necessary compressed air for example for the braking system of the commercial vehicle.
  • oil-filled compressors in particular also screw compressors, are known in which the task is to regulate the oil temperature.
  • This is usually achieved by having an external oil cooler that is connected to the oil-filled compressor and the oil circuit via a thermostatic valve.
  • the oil cooler is a heat exchanger which has two separate circuits, the first circuit being provided for the hot liquid, that is to say the compressor oil, and the second being provided for the cooling liquid.
  • air, water mixtures with an antifreeze agent or another oil can be used as the coolant.
  • This oil cooler must then be connected to the compressor oil circuit via pipes or hoses and the oil circuit must be secured against leaks.
  • This external volume must also be filled with oil, so that the total amount of oil is also increased. This increases the system inertia.
  • the oil cooler must be housed and fastened mechanically, either by means of brackets located around it or by a separate bracket, which requires additional fastening means, but also installation space.
  • Screw compressors usually have oil filters in order to filter out any particles in the screw compressor and to ensure that the screws in particular are lubricated.
  • oil filters in order to filter out any particles in the screw compressor and to ensure that the screws in particular are lubricated.
  • Such an arrangement is for example from DE 42 34 391 B4 known.
  • a screw compressor for a commercial vehicle with the features of claim 1. According to this, it is provided that a screw compressor for a commercial vehicle is provided with a housing, with an oil sump being provided in the housing when the screw compressor is ready for operation and installed and with the A magnet is arranged in the oil sump.
  • the invention is based on the basic idea that in the present design mainly magnetic particles contaminate the oil and that such particles must be filtered out by an oil filter.
  • an oil filter In order to prevent an oil filter from clogging, it makes sense to use an alternative and / or additional option for a particle trap. This is achieved by a magnet. Due to the arrangement of the magnet in the oil sump, preferably at the deepest point in the oil sump, it is achieved that the number of magnetic particles in the oil is reliably reduced The oil filter can thus be made smaller or even omitted entirely.
  • the screw compressor does not have an oil filter. This simplifies the construction of the screw compressor, since one component is omitted and, moreover, fewer oil lines have to be provided in the housing of the screw compressor or also external oil lines around the screw compressor. There is also no wear part of the screw compressor, since the oil filter would have to be replaced after a certain period of time due to clogging. This is no longer necessary.
  • the housing has a housing body and a housing cover, the magnet being arranged in the housing body.
  • the arrangement in the housing body enables simple and reliable fastening, but also assembly of the magnet. Even when the screw compressor is serviced and overhauled, the magnet is easily accessible and can easily be cleaned or replaced.
  • the housing has a housing body and a housing cover, the magnet being arranged in the housing cover.
  • a baffle plate is arranged in the housing and that the magnet is arranged below the baffle plate in the oil when the screw compressor is ready for operation and installed.
  • the baffle makes it possible for the movement of the oil in the housing to be restricted and the effect of centrifugal forces and inertial forces reduced when the screw compressor is in motion, especially when the utility vehicle is in operation and when driving.
  • the arrangement of the magnet below the baffle plate when the screw compressor is ready for operation and installed ensures that the magnet is essentially always bathed in the oil and can thus perform its function as a particle trap.
  • the magnet can be designed as an essentially cylindrical disk. This enables simple manufacture, but at the same time also a comparatively large surface to which particles can adhere. However, the magnet can also have any other shape.
  • the magnet can be fastened in the housing by means of a spacer. This makes it possible for the oil to wash around both the front and the rear of the magnet.
  • the spacer can have a screw bolt and / or a spacer element.
  • the spacer element can be, for example, a spacer sleeve pushed onto a screw bolt.
  • Fig. 1 shows a schematic sectional view of a screw compressor 10 in the sense of an exemplary embodiment of the present invention.
  • the screw compressor 10 has a fastening flange 12 for the mechanical fastening of the screw compressor 10 to an electric motor not shown in detail here.
  • the screw 18 meshes with the screw 16 and is driven by this.
  • the screw compressor 10 has a housing 20 in which the essential components of the screw compressor 10 are accommodated.
  • the housing 20 is filled with oil 22.
  • an inlet connector 24 is provided on the housing 20 of the screw compressor 10.
  • the inlet connector 24 is designed such that an air filter 26 is arranged on it.
  • an air inlet 28 is provided radially on the air inlet connector 24.
  • a spring-loaded valve insert 30 is provided, designed here as an axial seal.
  • This valve insert 30 serves as a check valve.
  • An air supply channel 32 is provided downstream of the valve insert 30 and supplies the air to the two screws 16, 18.
  • an air outlet pipe 34 with a riser 36 is provided on the output side of the two screws 16, 18.
  • a temperature sensor 38 is provided, by means of which the oil temperature can be monitored.
  • a holder 40 for an air / oil separator 42 is also provided in the air outlet area.
  • the holder 40 for the exhaust filter has in the assembled state in the area facing the floor (as also in FIG Fig. 1 shown) the exhaust filter 42 on.
  • a corresponding filter screen or known filter and oil separation devices 44 which are not specified in detail, are also provided inside the exhaust filter 42.
  • the holder for the exhaust filter 40 has an air outlet opening 46, which lead to a check valve 48 and a minimum pressure valve 50.
  • the check valve 48 and the minimum pressure valve 50 can also be formed in a common, combined valve.
  • the air outlet 51 is provided downstream of the check valve 48.
  • the air outlet 51 is usually connected to correspondingly known compressed air consumers.
  • a riser 52 is provided which has a filter and check valve 54 at the outlet of the holder 40 for the exhaust filter 42 when it passes into the housing 20.
  • a nozzle 56 is provided in a housing bore downstream of the filter and check valve 54.
  • the oil return line 58 leads back approximately to the middle area of the screw 16 or the screw 18 in order to supply oil 22 again.
  • An oil drain plug 59 is provided in the bottom area of the housing 20 in the assembled state. Via the oil drain screw 59, a corresponding oil drain opening are opened through which the oil 22 can be drained.
  • the housing 20 In the lower area of the housing 20 there is also the extension 60 to which the oil filter 62 is attached.
  • the oil 22 is first fed to a thermostatic valve 66 via an oil filter inlet channel 64 which is arranged in the housing 20.
  • thermostat valve 66 a control and / or regulating device can be provided, by means of which the oil temperature of the oil 22 located in the housing 20 can be monitored and adjusted to a setpoint value.
  • a nozzle 72 is also provided, which is provided in the housing 20 in connection with the return line 68.
  • the cooler 74 is connected to the extension 60.
  • a safety valve 76 In the upper area of the housing 20 (in relation to the assembled state) there is a safety valve 76, via which an excessively high pressure in the housing 20 can be reduced.
  • a bypass line 78 which leads to a relief valve 80, is located upstream of the minimum pressure valve 50. Air can be fed back into the area of the air inlet 28 via this relief valve 80, which is controlled by means of a connection to the air supply 32.
  • a vent valve (not shown in more detail) and also a nozzle (diameter reduction of the supply line) can be provided in this area.
  • an oil level sensor 82 can be provided approximately at the level of the line 34 in the outer wall of the housing 20.
  • This oil level sensor 82 can be, for example, an optical sensor and can be constructed and set up such that it can be recognized on the basis of the sensor signal whether the oil level is above the oil level sensor 82 during operation or whether the oil level sensor 82 is exposed and the oil level has fallen accordingly as a result.
  • an alarm unit can also be provided that outputs or forwards a corresponding error message or warning message to the user of the system.
  • the function of the in Fig. 1 shown screw compressor 10 is as follows: Air is supplied via the air inlet 28 and reaches the screws 16, 18 via the check valve 30, where the air is compressed. The compressed air-oil mixture, which rises with a factor of between 5 and 16 times compression after the screws 16 and 18 through the outlet line 34 via the riser pipe 36, is blown directly onto the temperature sensor 38.
  • the air which still partially carries oil particles, is then guided via the holder 40 into the exhaust filter 42 and, if the corresponding minimum pressure is reached, reaches the air outlet line 51.
  • the oil 22 located in the housing 20 is kept at operating temperature via the oil filter 62 and possibly via the heat exchanger 74.
  • the heat exchanger 74 is not used and is also not switched on.
  • the corresponding connection takes place via the thermostatic valve 68.
  • oil is fed to the screw 18 or the screw 16, but also to the bearing 72, via the line 68.
  • the screw 16 or the screw 18 is supplied with oil 22 via the return line 52, 58; here the oil 22 is purified in the exhaust filter 42.
  • the screws 16 and 18 of the screw compressor 10 are driven by the electric motor, not shown in detail, which transmits its torque via the shaft 14 to the screw 16, which in turn meshes with the shaft 18.
  • the relief valve 80 ensures that in the area of the supply line 32, the high pressure that prevails in the operating state, for example on the outlet side of the screws 16, 18, cannot be locked in, but that, especially when the compressor starts up, always in the area of the supply line 32 there is a low inlet pressure, in particular atmospheric pressure. Otherwise, when the compressor starts up, a very high pressure would initially arise on the output side of the screws 16 and 18, which would overload the drive motor.
  • Fig. 2 shows a perspective view of part of the screw compressor 10, namely the housing body 20a of the housing 20.
  • a corresponding receptacle is provided in the housing body 20a, the rotor housing 20b for the two screws 16 and 18.
  • a baffle 100 with oil passage slots 102 is provided below this rotor housing 20b below this rotor housing 20b .
  • the oil sump of the oil 22 is located below the baffle plate 100 in the assembled and operationally ready state.
  • a magnet 104 is provided in the oil sump of the oil 22 in the operationally ready and assembled state.
  • the magnet 104 is fastened to the housing body 20a by means of a spacer 106, which here consists of a screw bolt 108 and a spacer sleeve 110 not shown in detail.
  • the screw compressor 10 has in Fig. 2
  • the embodiment shown does not have an oil filter 62. This is omitted and is completely replaced by the magnet 104.
  • the magnet 104 is designed as a substantially cylindrical disk.
  • the magnet 104 is completely surrounded by the oil 22 with the exception of the small area on the housing body 20a facing the small area in which the spacer 106 passes through the magnet 104.
  • the housing cover of the screw compressor 10 is in Fig. 2 Not shown.
  • the function of the magnet 104 can be described as follows: The magnetic particles floating in the oil 22, which get into the oil 22, for example through abrasion of the intermeshing screws 16 and 18 or the bearings or other moving parts of the screw compressor 10, are removed from the oil 22 by the magnet 104, which acts as a particle catcher here filtered out and tightened.
  • the magnet 104 thus acts as a particle trap and thereby cleans the oil 22.
  • the oil filter 62 can thus be dispensed with, since it is no longer necessary to carry out further filtering of the oil 22.
