DSK 0-050-08-US (09.04) for mounting plates General information s are used in large oil circulation lubrication systems. The task of a flow limiter is to divide up the volumetric flow of the main line into parallel individual volumetric flow quantities and to limit these according to requirement, or to keep them constant. The volumetric flow generated is independent of the system pressure and virtually independent of viscosity. The flow limiter was developed specially for mounting plates. The advantage of this design is its simple and compact construction. Using interchangeable plug-in nozzles, the volumetric flow of the flow limiter can be set stepwise from 0.09 to 8.18 l/min. This also makes subsequent adjustments possible (necessary when the unit is modified, e.g.). Tedious resetting and measuring are unnecessary. SP/SMB 8... The volumetric flow can be monitored simply and safely with a signal transmitter or proximity switch (which is also subsequently screwed in). A fault signal occurs when the volumetric flow drops to approx. % of the nominal volumetric flow. Mode of operation Functional diagram With the flow limiter, the total volumetric flow Q is divided up by the parallel layout of the on the mounting plate into individual flow lines Q i. The system pressure, being the input pressure p 1 is thus maintained for all flow limiters. Every has a control plunger with a plug-in nozzle as a differential pressure regulator. The differential pressure (p 1 -p 2 ) at the interchangeable plug-in nozzle D 1 in the control plunger is based on a balance of forces p 1 A = p 2 A + F resp.. p1/2 = p 1 - p 2 = F/A = constant. It follows that: The difference in pressure in front of and behind the variable jet D 2 is maintained constant by a balance in pressure. The condition for this function is that the system pressure p 1 is always greater than the sum of the pressure drops in and after each flow limiter. p 1 > p1/2 + p 3 For this reason the pump volume flow should exceed all individual flow quantities by approx. 15 %, i.e., Q = 1.15 ( Q i ). p 1 pressure upstream of the plug-in nozzle D 1 p 2 pressure downstream of the plug-in nozzle D 1 p 3 pressure downstream of D 2 D 1 D 2 RK F A plug-in nozzle throttle control plunger spring pressure cross-section of the control plunger Fig. 1 Functional diagram SP/SMB 8. www.vogelag.com

From here, the lubricant then reaches the lubricating point directly via the flow limiter (4), or via the progressive distributor (3) or flow divider (6) which are connected to it. The signal transmittersor proximity switches which are screwed into the flow limiters (4) monitor the volumetric flow.

Remove stop screw (hexagonal 30 mm) or signal transmitter or proximity switches with sealing ring slowly Caution! Escaping oil may be hot! Remove control plunger, plug-in nozzle with sealing ring and pressure spring. Remove plug-in nozzle from control plunger. Use a rod approx. ø 7 in diameter, if necessary, (on no account a pointed instrument such as a needle). Insert new plug-in nozzle with sealing ring into the control plunger as far as it will go. Insert pressure spring (without crossing the thread) into the bore hole. Insert control plunger with new plug-in nozzle on top of the pressure spring into the bore hole without crossing the thread. Check control plunger for smooth action by pressing against the pressure spring. Crossing the thread causes malfunctions. Screw in stop screw or signal transmitter with sealing ring.
