Chain lubrication unit WS-E

Transcription

1 Product description Chain lubrication unit WS-E APPLICATION The central lubrication system WS- E is used for automatic and metered lubrication of chains, joints, rollers, hinges, etc. This system is also suitable for application with oil wetting of integral parts (engine crankshaft). PRODUCT CHARACTERISTICS Chain lubrication with oil Pump with a delivery rate of 1.2 liters Surface light grey RAL 7004 DESIGN The chain lubrication aggregate WSE consists of: 1. Electrical switching device 2. Opto-electronical proximity switch * 3. Reflector (deleted with inductive proximity switch) 4. Gear pump aggregate with mounted solenoid valve and integrated throttle. 5. Pipe 6 x Spray nozzle 7. Metering element ZE-E 8. Manifold VZE * The optoelectronic proximity switch with reflector may optionally be replaced by an inductive proximity switch. FUNCTION After switching on the system, the chain lubrication aggregate starts and circulates oil without pressure via the opened solenoid valve and the opened restrictor. As soon as an impulse is initiated via the existing proximity switch (optoelectronic or inductive) by the chain, the solenoid valve closes and the oil circulation is interrupted. The main line leaving the pump and the following metering elements ZE-E are admitted rapidly with pressure. The metering elements release the stored lubricant quantity with speed to the friction points via spray nozzles (in form of a directed drop). When the chain leaves the switching range of the proximity switch, the solenoid valve opens, the pressure in the main line decreases and oil is stored in metering element ZE-E for the next lubrication cycle. The above circulation recommences. 1
