 真空设备的安全信息

Vacuum pumps and vacuum gauges in category 3 are intended for connection

to equipment in which during normal operation explosive atmospheres

caused by gases, vapors or mists normally don’t occur; or, if they

do occur, are likely to do so only infrequently and for a short period only.

Equipment in this category ensures the requisite level of protection during

normal operation.

The use of gas ballast or the operation of venting valves is only permitted

if thereby explosive atmospheres normally don’t occur in the interior

of the equipment or, if they do occur, are likely to do so only infrequently

and for a short period.

The pumps are marked with ”X” (according to EN 13463-1), i.e., restrictions

of the operation conditions:

• The equipment is designated for a low degree of mechanical stress

and has to be installed in a way so that it cannot be damaged from

outside.

Pumping units have to be installed so that they are protected against

shocks from the outside and against glass splinters in the event of

breakage (implosion).
