Spray nozzles for grease up to NLGI grade 2
These spray nozzles are used to spray grease up to NLGI grade 2 on surfaces, e.g. on the tooth surface of large gears.
The grease is supplied by pulsation via inlet S by, for instance, a progressive feeder and is blown out by compressed air flowing continuously during the entire lubrication period. Compressed air in connected to inlet L1, optionally to L2. Depending on the construction of the spray nozzle, the spray pattern is either rectangular (SP31) or circular (SP32). Several spray nozzles may be connected in series to one compressed air line. At the last spray nozzle of one line, however, one inlet borehole for the compressed air must be closed with a screw plug. This also applies where there is only one spray nozzle.
