Abstract
A cooling and flushing arrangement (1) for a tool (10), has a coolant and flushing agent (2) in a closed storage tank (3), which is connected to a suction pump (4) and has a closed flushing circulation system (6) running from the storage tank (3) through a filter (8), connected via a pressure pump (7) and through a collecting member (11) associated with the tool (10), with a suction line (12) running back to the storage tank (3). A reservoir circulation system (13) for the coolant and flushing agent (2), contains a reservoir (14) connected to the storage tank (3) via a float valve (15) situated in the storage tank (3), and is connected at another location in the flushing circulation system (6) to the reservoir (14) via a valve (16).
Claims11
A cooling and flushing arrangement for a tool (10) including a coolant and flushing agent (2) contained in a closed storage tank (3), a suction pump (4) connected to said storage tank (3), a closed flushing circulation system (6) extending in a supply line from said storage tank (3) through a filter (8) with a pressure pump (7) located in the pipeline between said storage tank (3) and said filter (8), said supply line extending from said filter (8) to a collecting member (11) enclosing at least a part of said tool (10), said flushing circulation system (6) including a suction line (12) extending from said collecting member (11) to said storage tank (3), said flushing circulation system (6) is combined with a reservoir circulation system (13) for said coolant and flushing agent (2) comprising a reservoir (14) connected to said storage tank (3) via a float valve located in said storage tank (3) and said reservoir (14) connected at a position spaced from the connection to said storage tank (3) to said flushing circulation system (6) via a drain valve (16), said drain valve (16) forms a filter concentrate drain at a lower end of said filter (8).
A cooling and flushing arrangement, for a tool (10) including a coolant and flushing agent (2) contained in a closed storage tank (3), a suction pump (4) connected to said storage tank (3), a closed flushing circulation system (6) extending in a supply line from said storage tank (3) through a filter (8) with a pressure pump (7) located in the pipeline between said storage tank (3) and said filter (8), said supply line extending from said filter (8) to a collecting member (11) enclosing at least a part of said tool (10), said flushing circulation system (6) including a suction line (12) extending from said collecting member (11) to said storage tank (3), said flushing circulation system (6) is combined with a reservoir circulation system (13) for said coolant and flushing agent (2) comprising a reservoir (14) connected to said storage tank (3) via a float valve located in said storage tank (3) and said reservoir (14) connected at a position spaced from the connection to said storage tank (3) to said flushing circulation system (6) via a drain valve (16), a drive (17) forms the driving means for said suction pump (4) and said pressure pump (7).
