1 Scope of application
iSHAN centralized lubrication systems are designed to lubricate ball bearings, flat
bearings, flat slideways, circular slideways, linear guides, cams, gears, chains, etc..
iSHAN centralized lubrication systems are suitable for the lubrication of various
machines, such as lathes, mills, presses, planner, grinder, etc. It is fit to control different
lubricating points at the same time against different machines.
The YAE-A1 / A2 lubrication units are suitable for using lubricant with a viscosity range
at 30 to 250 cSt during it is running. Only new lubricant shall be used.
The max. discharge pressure for YAE-A1 model is 10 kgf/cm2, and YAE-A2 model is 20
kgf/cm2. The lubrication unit contains a pressure regulating valve for operating stably and a
pressure relief valve in order to prevent injury, death, or property damage. YAE-A2 can
release built-in pressure in the main line through dump valve at the interval time.
For safety, a pressure switch should be mounted to monitor the system. The pressure
switch monitors whether the required pressure build-up occurs in the centralized lubrication
system during the pump cycle time and detects any leaking or lubrication connection damage.
The level switch is design to monitor the filling level and shut down the lubrication unit
when the lubricant is insufficient. To get further safety, the lubrication unit can connect to
other monitored device properly to enhance the alarm system.
The design of YAE-A series is to operate intermittently with an interval-controlled supply
of lubricant to the lubrication point. The interval time can be set from 1 to 999 per
second/minute. The lubrication time can be set from 1 to 999 per second. The default time
unit of lubrication unit is second for lubrication and minute for intermittence. The user can
adjust time for lubrication quantity and interval depends on the application.
The maximum discharge rate of YAE -A1 pump is 300 ml/min.
The maximum discharge rate of YAE -A2 pump is 150 ml/min.
