6.7.2 Connection of aerosol lines to an MQL system with bypass control
See Figure 34
On an MQL system with bypass control, the
aerosol flow must be divided by a Y-piece at
the end of the aerosol line coming from the
aerosol generator (
2
), as close as possible to
the tool spindle. One of the two downstream
aerosol lines is then routed to the tool
spindle (
8
), while the other aerosol line is to
be routed through the provided bypass valve
(
6
) either back to the refill reservoir (de-
signed for this application) or the customer’s
exhaust air system.
• Route the aerosol line (
1
) from the aero-
sol generator (
2
) to the immediate vicin-
ity of the tool spindle (
8
)
• Install the supplied Y-distributor at
the end of the aerosol line (
1
), as close
as possible to the entrance to the tool
spindle
• Connect both outlets of the Y-distributor
(
3
) to the aerosol lines
• Route and connect one of the two aero-
sol line (
4
) to the tool spindle
There are two ways to route the other
aerosol line, which leads through the bypass
valve:
1. Routing to exhaust air system on ma-
chine tool
• Secure the bypass valve (
6
) at an appro-
priate location in the machine tool
• Connect the inlet side of the bypass valve
(
6
) to the aerosol line (
5
) coming from
the Y-distributor (
3
).
• Connect the outlet side of the valve (
6
), in
which the bypass restrictor (
9
) has been
pre-installed, to the aerosol line (
5
) and
route the line to the suction area of the
machine tool.
• Use the supplied cable to establish the
electrical connection between the bypass
valve (
6
) and the bypass control (Chapters
7 and 8).
2. Routing to oil reservoir (accessory) of the
MQL system
The bypass line can also return to the oil re-
filling reservoir. As this is system-dependent,
consultation with the SKF dealer or the SKF
Customer Service department is required.
