Flow limiter SP/SMB 10...

General information
Flow limiters are used in large circulating-oil lubrication systems.The task of a flow limiter is to divide up the volumetric flow of themain line into parallel individual volumetric flow quantities and to“limit” these according to requirements, or to keep themconstant.
The volumetric flow produced does not depend on the systempressure and is nearly independent of viscosity. It is alsopossible to switch from the rated volumetric flow of the SP/SMB10 to a reduced starting flow (1 : 4) to keep cold bearingsfrom overflowing
The SP/SMB 10... flow limiter was developed specially formounting plates. The advantage of this design is its simple andcompact construction.
Using interchangeable plug-in nozzles, the volumetric flow of theflow limiter can be set stepwise from 0.210 to 8.18 l/min.Thatmakes it possible to adjust the volumetric flow rates at a laterdate.
The SP/SMB 10... Group comes with a visual/electronic gearwheel-type flow indicator.

Flow limiter SP/SMB10 ...
Design
The SP/SMB 10 flow limiter consists of the following:
� flow limiter housing (with sensor)
� flow limiter regulating assembly (with control piston, plug-innozzle and pressure spring)
� gear pair
� flow limiter cover (with sight glass, seals, plugs and fasteningscrews)
� baseplate.
The housing, gears and cover consist of an anodized aluminumalloy to ensure corrosion-resistance and low weight. A roundglass disk conforming to DIN 8902 (pressed hard glass) is usedfor the sight-glass pane. The pane floats in the cover to avoiddistortion and premature failure. The housing accommodates asensor that is actuated by pin magnets embedded in the gear.

Mode of operation
With the flow limiter SP/SMB 10...flow limiter, the total volumetricflow Q is divided up into individual flow lines Q, by the parallellayout of the volume limiter on the mounting plate. The systempressure, being the input pressure p1, is thus maintained for allflow limiters.
Every flow limiter has a control piston with a plug-in nozzle as adifferential pressure regulator.
The differential pressure (p1-p2) at the interchangeable plug-innozzle D1 in the control piston is based on a balance of forces
p1 • A = p2 • A + F resp.. p1/2 = p1 - p2 = F/A = constant.
It follows that:
The difference in pressure in front of and behind variablenozzle D2 is held constant by a balance in pressure.
Only one respective nozzle of the two plug-in nozzles D1 and D2
is active in this respect. In the starting phase, oil flows throughboth nozzles, but only the smaller of the two (D1) is active.
Starting phase
p II > p I
The starting volumetric flow should not, however, be greater than1/4 the volumetric flow in normal operation.
Operation
In normal operation (see Fig. 3 for changeover-valve switchposition) only nozzle D2 is actuated.
pI > pII
For this function the system pressure pI must always be greaterthan the sum of the pressure drops in and downstream of eachflow limiter.
p I > (p1 - p2) + p3
For this reason the pump´s volumetric flow should exceed all theindividual flow quantities by approx. 15 %, i.e.,
Q = 1,15 • ( ∑ Qi ).
The downstream gear wheel-type flow indicator uses a dynamicpulse generator (24 V DC) to emit a continuous sequence ofpulses proportional to the volumetric flow. The proportionalityfactor K1 is derived from the swallowing capacity of onerevolution of the gear pair (K1 = 12.0 ml/pulse).
The sequence of pulses can be displayed and monitored bypulse-monitoring equipment, group monitoring units or a centralevaluation station.

Example of a circulating-oil lubricationsystem
Before lubrication begins the lubricant is heated inside thepressurized-oil station (1). The delivery line (2) cuts in when thespecified lubricant temperature is reached. The lubricant nowflows back to the pressurized-oil station (1) via the delivery line(2), enabled warm-up lines (3) and return line (4). (The flowlimiters (5) are not monitored in this period of time.) The flowlimiters (5) are switched to when the specified lubricanttemperature is reached. The hydraulic (6) and/or electricalchangeover valve (7) on the flow limiters (5) actuates startupplug-in nozzle D1. This nozzle reduces the rated volumetric flowto a lower starting flow of 1:4. At the same time, electricalmonitoring of the flow limiters is activated.
A thermostat (8) on the return line (4) determines the returninglubricant’s temperature. When the specified lubricanttemperature is reached, the hydraulic (6) and/or electricalchangeover valve (7) switches to normal-operation nozzle D2.The nozzle adjusts to the full rated volumetric flow.
Group pulse monitoring units (9) see to evaluation of the signalsarriving from the flow limiters (5). Progressive feeders (10) can beadditionally installed downstream of the flow limiters (5).

Replacing plug-in nozzles
• Interrupt oil feed to flow limiter above shutoff valve(at oil filter, if required).
� Control piston held under spring pressure!
• Slowly screw out stop screw (hexagonal head, WAF 12)together with washer.
� Burn injury hazard!
Escaping oil is possibly hot!
• Remove control piston with plug-in nozzles (D1/D2) andpressure spring.
� Attention!
When reinstalling the plug-in nozzles make sure theyare not mixed up! Consult the rated volumetric-flowtable on pages 4-5 for the selection of plug-innozzles.
Dismantling/installation of plug-in nozzle D1
• Dismantling/installation of plug-in nozzle D1
• Remove plug-in nozzle D1 (with washer) from controlpiston.
� A roughly ø 6 mm rod (never use a pointed object like,for instance, a scriber) can be used to help press it out.
• Press new plug-in nozzle D1 and washer firmly into thecontrol piston all the way to the stop with the nozzleopening pointing upward (nozzle type legible).
Dismantling/installation of plug-in nozzle D2
• Loosen and remove retaining ring from the controlpiston.
• Remove plug-in nozzle D2 (with washer) from the controlpiston.
� A roughly ø 6 mm rod (never use a pointed object like,for instance, a scriber) can be used to help press it out.
• Press new plug-in nozzle D2 and washer firmly into thecontrol piston all the way to the stop with the nozzleopening pointing upward (nozzle type legible).
• Insert retaining ring in control piston.
• Insert pressure spring in the borehole.
• Insert control piston with new plug-in nozzle(s) in theborehole over the pressure spring without skewing.
• Check to make sure the control piston moves easily bypressing it against the pressure spring. Skewing leads tomalfunctions.
• Screw in stop screw with washer.
• Open the shutoff valve.
