Modular design, with gearwheel-type flow indicator andbypass system, for oil circulation lubricating systems

www.vogel-fluidtec.de

� Modular design to adapt the lubricating system to machinesand systems anytime.

� Flow adaption by adjusting the throttle screw. The oil flow iscontinuously adjustable even while the machine or system isrunning.

� The setting range of the SMD 1A flow meter is from 0,05 and0,25 l/min. The setting range of the SMD 2 flow meter is from0.1 and 4.4 l/min when using a fine throttle screw and from 4to 8.0 l/min with a coarse throttle screw. The SMD 3 flowmeter is available with a setting range of 4 to 40 l/min.

� Electric wheel monitoring (NAMUR switch). The combinationof optical and electrical monitoring guarantees the bestpossible flow monitoring.

� User-friendliness thanks to a bypass system. If anyservicing work should become necessary, it can be carriedout without changing the setting of the throttle screw andwithout interrupting the lubricant supply.

� Optimal flushing block for easy service.

Flow meters of the SMD 1A, SMD 2 and SMD 3 series aremainly used in oil circulation lubricating systems for papermachines.

They stand out especially for their reliability, easy maintenanceand flexibility.

General

The individual flow meters are designed to divide the oil flow ofthe main line into defined flows or block flows if necessary.

Throttling devices have proved to be reliable and flexibleespecially in papermachines that often have several hundredsof lubricating points. Throttle systems are used whenever minoradjustments and corrections of the lubricant supply must beperformend while the machine is running.

For better serviceability and reduced downtime a bypassfunction was integrated into the SMD1A, SMD 2 and SMD 3flow meters.

This makes it possible to service the flow meters withoutchanging the throttle adjustment and with no impact on the oilflow. The bypass function is part of the SMD 1A, SMD 2 andSMD 3 scope of supply.

Mode of operation of the throttling device

The lubricant coming from the supply line flows from the inlet ofthe throttle housing into the wheel chamber of the gearwheel-type flow indicator and over the gear wheels to the throttle.

The flow is regulated by selecting (fine throttle or coarse throttle)and setting the throttle screw.

After having passed the throttle screw the dosed lubricant flowsto the outlet of the throttle housing.

Mode of operation of the gearwheel-typeflow indicator

The lubricant coming from the supply line flows from the inlet ofthe throttle housing into the wheel chamber of the gearwheel-type flow indicator and over the gear wheels to the throttle.

This flow generates a rotation of the gear wheels in the wheelchamber. A NAMUR switch installed above one of the gearwheels detects the rotation (pulse detetion) of the gear wheels,indicating the flow rate at the same time.

The number of pulses as an equipment of the flow by theNAMUR switch (flow rate) depends on the setting detected ofthe throttle screw and the resulting flow.
