Chain Lubrication Unit WS-E
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 internal parts (engine crankshaft).
Product Features
- Chain lubrication with oil
- Pump with a delivery rate of 1.2 l /min
- Surface: light grey RAL 7004
Design
The chain lubrication system WS-E consists of:
- Electrical switching device
- Optoelectronic proximity switch*
- Reflector (not required with inductive proximity switch)
- Gear pump with integral solenoid valve and throttle
- Pipe 6 x 0.7
- Spray nozzle
- Metering element ZE-E
- Manifold VZ-E
* The optoelectronic proximity switch with reflector may be replaced by an inductive proximity switch.
Function
After switching on the system, the chain lubrication system starts and circulates oil without pressure via the opened solenoid valve.
As soon as an impulse is initiated via the proximity switch (optoelectronic or inductive) by the chain, the solenoid valve closes and the oil is directed to the metering elements. The metering elements release the stored lubricant quantity with speed to the friction points via spray nozzles (in the 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 the ZE-E meeting element, ready for the next lubrication cycle.
The above sequence continues automatically.
As the metering element receives lubricant, the precharge of lubricant from the previous cycle is discharged via the spray nozzle as a directed drop of lubricant, and is delivered to a predefined point on the chain at high speed. Once pressure to the metering element is relieved, the precharge of lubricant in the metering element moves into the discharge chamber, ready for the next charge cycle.
Micro Fog Oiler ON-L
Micro Fog Oiler ON-L
Micro Fog Oiler for lubricating bearings.
Application
Micro Fog Oiler for lubricating bearings.
Only a small fraction of the oil quantity passing through the sight dome (approximately 5% according to grade and temperature) enters the air line as micro fog. Suitable for use in systems with predominantly high-efficiency reclassifiers installed downstream, but also suitable in conjunction with standard reclassifiers.
Both reclassifier types, however, cannot be combined in the same system due to their differing operating pressure ratings.
Product Features
- Venturi nozzle
- Adjustable discharge volume
- Allows for the movement of lubricant over long distances in branched pipe networks
- Lubricant: lubricating oils without solid additives
- Oil viscosities ISO VG 7 to DIN 51519
- Surface: signal grey RAL 7004
Function
The compressed air flowing through the venturi nozzle sets up a pressure difference between the reservoir and the sight glass. Oil is thereby forced through a system of pipes and channels to the Venturi nozzle where it is atomised into an oil mist. The flow of oil mist passes through the hollow screw at high velocity; in the process, 95% of the oil falls back into the reservoir. Only the very fine droplets which are transportable over long distances, reach the outlet of the oiler.
Oilers that are capable of delivering oil at a constant low flow rate, independent of the level of oil in the reservoir, have an air-driven oil pump installed in the oil receiver. For setting the correct operating conditions, all the units have a supplementary air screw, by means of which the oil mist pressure can be varied without varying the rate of delivery of the oiler.
The oilers have an additional adjustment spindle for charging the rate of oil delivery, which are marked accordingly.
Micro Fog System
Micro Fog System
A micro fog lubricator uses a venturi to create an airborne mist of extremely fine oil particles in compressed air.
Application
A micro fog lubricator uses a venturi to create an airborne mist of extremely fine oil particles in compressed air. The low weight of the oil particles enables them to be carried in the air stream over considerable distances.
Reclassifier nozzles at the lubrication points condense the oil-mist into larger oil droplets, suitable for lubrication.
The patented high efficiency reclassifier achieves pollution-free lubrication. The use of a pack of small pellets has a multiple reclassifying effect and reduces oil residue in the vented air to one percent. The system can be designed to supply small and large installations with a constant supply of oil without any moving parts either to convey or to meter the oil.
SkyJet Air/Oil Lubrication
Application
Lubrication with oil and compressed air is today widely adopted and accepted within hi-tech engineering applications. For example, in steel and aluminium mills, this method of lubrication is being used on continuous casting plants, cold and hot strip mills and various types of rolling mills. An automated lubrication system ensures operational safety, long service life and low maintenance requirements along with minimal lubricant consumption and is eco-friendly.
Product Features
- Minimal consumption of lubricant through precise, calculated dosing.
- The possibility of different quantities of lubricant at the divider valve outlets.
- Air acts as a transporting and bearing sealing medium.
- The air/oil mixture has excellent adhesion properties, even at the bearing surfaces.
- Improved heat removal.
- Environmentally friendly lubrication.
Function
From the oil tank complete with heater, level switch and flow meter, the oil is pumped via a filter to the oil/air mixing unit. The electric control panel monitors the solenoid valve, filter differential pressure and the oil level in the tank. The oil/air mixing unit has its own electrical panel that controls theoil and air solenoid valves. The oil is now transported in the tube by the air to the master divider.
The master divider can have from 2 to 6 outlets and divides the air/oil flow to the respective slave dividers. The slave dividers, again, can have from 2 to 6 outlets and the air/oil delivered lubricates and cools the bearings of the rollers.
Wheel Flange Lubrication RE
Wheel Flange Lubrication RE
Application
- Wheel flange lubrication helps to reduce noise levels on any type of train wheels.
- Wheel flange lubrication reduces the friction and wear on both the wheel flange and the rail.
Product Features
- Up to 15% saving in driving energy
- Reduction of wheel flange wear by up to 80%
- Cost reduction due to greater reprofiling intervals
- Preservation of environment by noise reduction
Function
The air operated pump delivers a metered quantity of lubricant, and once the 2/2 way solenoid is opened, the compressed air and lubricant is delivered and sprayed onto the wheel flanges via the respective spray nozzles. The process is completely automated and controlled by a rogrammable control system.
