The invention relates to a sand dosing and blocking device (1) for sand spreading systems for vehicles, particularly rail vehicles with drive, the invention having a sand supply container (2) with an outlet opening (4), which can be closed by a closing element (3), for the dosed release of sand to a conveyor unit (5) which is preferably pneumatically activated, wherein the closing element (3) is formed by a lifting rod (7) of an electrically activated lifting magnet (6). According to the invention, the lifting magnet (6) is arranged inside the sand supply container (2) in the area of the outlet opening (4).
摘要:
A sand spreading device in rail-borne high-speed vehicles in which a metering device and a conveying device are provided. For preventing a lateral discharge of the conveyed sand, both devices do form one unit, yet are separately controllable. When using a bucket wheel (Z) controlled by a vehicle speed indicator (FT), it will be possible to achieve an exact, infinitely variable amount of sand, or conveyance, respectively.
摘要:
The invention relates to a filter installation having at least one filter element for the filtering of a crude gas containing impurities, in particular particulate impurities. The crude gas flow to be filtered can be supplied to the filter installation via a crude gas line and at least two filter modules, each having at least one filter element, are provided. Each filter module is fluidly connected to the crude gas line via a module crude gas line through which a part of the crude gas flow can be supplied to the respective filter module. Each module crude gas line has a blocking member through which the supply of the respective partial crude gas flow can be interrupted for the cleaning of the filter element of the respective filter module.
摘要:
A method, and an apparatus, for monitoring the sand supply in a sand tank (2) of a sand-scattering device in vehicles, in particular in express trains. To prevent an insufficient sand supply, the sand-supply level is monitored by a inspection point.
摘要:
Metering or dosing device for sand spreading apparatuses with a metering piston for sealing off and releasing the throughflow opening for the material to be spread, in which the metering piston and the opposite housing wall of the passage hole have profiles overlapping each other so that a labyrinth-like outflow of the spread material results.
摘要:
A sand dosing and blocking device for sand spreading systems for vehicles, particularly rail vehicles with drive, has a sand supply container with an outlet opening which can be closed by a closing element for the dosed release of sand to a conveyor unit which is preferably pneumatically activated. The closing element is formed by a lifting rod of an electrically activated lifting magnet. The lifting magnet is arranged inside the sand supply container in the area of the outlet opening. Frequency control of the lifting magnet varies the dosed flow of sand, which may be varied in response to vehicle wheel speed.
摘要:
A system for spreading spreadings in front of the wheels of vehicles, in particular, rail vehicles, including at least one container for the spreadings, at least one device arranged below each spreadings container for metering the spreadings with an outlet opening for dispensing the metered spreadings and at least two devices for conveying the metered spreadings over at least two conveyor lines. The conveyor devices provided for the metering device are made up of a pneumatically operated multiple injector arranged beneath the outlet opening, with at least two separate cavities for the dispensing of the metered spreadings, with one compressed air connector per cavity, and a connector for the conveyor line in each cavity opposite the compressed air connection.
