Criteria For Choosing The Cutting Fluid In Hydraulic Environments

Three are the mainly widely established criteria for selecting the cutting fluid:

- The workpiece  material structure,
- The tool composition,
- The functional conditions of the cutting process.

Frequently is used mineral oil emulsions in water (emulsions) in diverse percentages depending on the rigidity of materials and cutting conditions. For example, emulsions diluted (between 3 and 8% oil) has little power and lubricant are used only for slow work. As increasing the amount of oil, which can reach up to 30%, increases power and are suitable lubricant for high speed work on solid supplies.

The unmixed oils are rarely used at present, either at cost (minerals) or by their low resistance to oxidation (plant and animal). An exceptional case, particularly suitable for superior pressure work, it is the oil to molybdenum disulfide, with exceptional lubricating qualities.

Lubrication and cooling of hydraulic transmission

In general, hydraulic transmission (oleohydraulic) are widely used in heavy equipment such as, for example, backhoes, dump trucks, loaders devices, etc.., And are characterized by elevated power transmission through a working fluid, normally oil , flowing through a pipeline at high pressure and that gets communicated to the actuator for movement.

However, the pumping action, the steep intensification in pressure, flow through conduits, narrowing, control valves and elements of work (cylinder engines) results in a gradual intensify in fluid heat, quite pronounced in several cases where it can reach up to 300 bar pressure at duty cycles of long-distance during times of high operation. It is Important to Decrease the high temperature of the lubricate for the reason that, otherwise, would modulate its properties, drastically dropping its viscosity and lubricating as well as other components of the heating installation, which can turn into unusable if it exceeds particular high temperature values. The  working fluid maintenance within the Best temperature levels to conserve and avoid its degradation requires installing temperature exchangers used for cooling water at temperatures between 20 and 25   C. In Specific cases, can be accomplished with a temperature exchanger air / oil.

It is well-known to conclude that in equipment and small power plants with probable stress levels relatively low, it is vital extra cooling of the working fluid, since the warm dissipation to ambient air through the circuits is sufficient to keep up the heat within the range recommended.

Lubrication and cooling pneumatic

In the pneumatic tools is in addition crucial to oil and cool the actuators that while working at low or standard pressure (up to 10 bar), do so at superior speeds due to low viscosity of air so that the waste of work items may become defendants. For this purpose, supply intakes machines such as saws, grinders, etc.., Installs a lubricator incorporating oil droplets into the air, thereby ensuring the lubrication.

Moreover, it is vital to examine air heat, which in this instance perform as a refrigerant and evacuate the air in the exhaust temperature generated by the relative movement and friction inside the actuators. The heat control is carried out air conditioning units at the compressor outlet.

Lubrication and cooling of internal combustion Mechanisms

The lubrication system consists of a pump that aims crankcase oil and distributes it to all points of importance.

In the two-stroke gasoline mechanisms adds a specified amount of oil to the fuel-air mixture entering the engine, thereby ensuring the protection of surfaces in constant contact.

Since the ignition happens at very high temperatures (200 to 300   C in the piston, for example) and the lubricant is unable to evacuate the high temperature in its entirety, it is crucial a special cooling system, although certain cases, such as bike engines, could be effected by air movement, it will normally be a system of forced water transmission, which incorporates a heat exchanger water-air (radiator) which can expand the efficiency of exchange using a heater.

In particular mechanisms it is crucial to also cool the lubricant itself by passing an oil-water temperature exchanger, which uses the water cooling circuit above.

Choosing the correct pneumatic tool

Selecting the correct pneumatic tool for a task enhances productivity greatly, improves quality control, and increases profits, reports Bellambie Mining and Industrial marketing manager Dudley Ward.

“To ensure optimum performance and extended operating life of pneumatic tools, proper selection, installation, use and regular maintenance is critical,” adds Ward.

Correct lubrication is one of the most important elements in the economic operation and maintenance of air tools.

To avoid tool failure, devices should be lubricated daily through the air inlet of multivane air motors and air hammers, or through air-line filters and lubricators.

Optimum pneumatic-tool performance also depends on a supply of clean, dry air at the correct pressure; while the tool is running, lower air pressure is recommended for screwdrivers.

Although a moisture trap and line filter effectively eliminate moisture and grit particles from the air, a compressor of adequate capacity and full-size air-supply lines are necessary to obtain optimum performance from pneumatic tools.

Suitable hose and fittings are also important in order to avoid air and pressure loss, and to facilitate speedy coupling and changing of air tools.

Sapco, which forms part of Bellambie Mining and Industrial’s automotive division, has been the sole distributor of Uryu pneumatic tools in Southern Africa for the past 20 years.

The tools, including bolt and nut setters, screwdrivers, abrasive tools, drills and tappers, as well as percussion tools and accessories, are available nationally from its outlets, which also offer a technical advisory and back-up service.

This range is assembled in Japan with precision-machined components, surpassing world-class standards.

Bellambie has introduced a new Uryu torque-measuring system to the market, designed to measure precisely the dynamic torque of oil-pulse and stall-type tools.

These UMS transducers, which are ideal for use in quality-control areas and workshop test facilities, consist of non-contact, magnetostrictive rotating transducers and a torque auditor, which provides automatic data storage and analysis of up to 1 000 readings.

To create a positive magnetostrictive effect when the transducer is excited under a load, grooves in two regions of the anvil surface are provided at about 45.

Part of Bellambie Mining & Industrial’s automotive division, Sapco, has extended its range of pneumatic tools to include the new Alpha series, which is the fifth generation in Uryu’s range of oil-pulse mechanism assembly tools.

The Alpha series has a nine-blade double-chamber air motor which produces a 50% higher power-to-weight ratio than tools of the same physical size, which use a conventional single-chamber air motor, explains Bellambie marketing manager Dudley Ward.

The range offers free speeds of between 3 100 r/min and 5 500 r/min, with minimal power ripple.

The double-blade pulse mechanism enables tools to cope efficiently with various tightening tasks, and to easily manage soft and hard joint conditions.

Bolt seating is efficiently performed, and torque spike on hard-joint applications, caused by spinning of the anvil, is reduced to a minimum.

Benefits during operation include low noise, reduced vibration and virtually no torque reaction.

Average air consumption is between 0,25 m3/min and 0,7 m3/min, depending on the model used, and efficient motor power provides optimum cycle time for different joint conditions.

This pneumatic tool has an advanced ergonomic design – a single hand-operation reverse lever enables easy forward/reverse movement, and an anti-vibration handle jacket provides perfect palm-fitting for the operator, enhancing comfort and safety.

With a surplus of both power and precision, a good pneumatic pin nailer is one of the best tools a carpenter or crafter can invest in.
