Hydraulic Systems Versus Pneumatic Systems in Dawson Creek

Since there are major differences between hydraulics and pneumatics, albeit with some similarities, choosing between the two systems is a complex decision, which engineers face from time to time. A good understanding of pneumatic and hydraulics systems benefits anyone interested in the subject matter. Outlined below are some situations where a pneumatic system is preferred over the Dawson Creek hydraulics systems.

Clean System

In a pharmaceutical plant or consumable goods factory, leaking oils from hydraulic systems is unacceptable. Pneumatic systems, on the other hand, work with nitrogen or other inert gases as the medium, which makes the system a preferred choice, particularly in the industries or plants where the likelihood of contamination is higher.

Systems Using Hydraulics Are Generally More Costly

In hydraulic systems, minor oil leaks could lead to major pressure loss, which means the machine or tool relying on the system will be incapable of delivering the level of output desired. To avoid possible oil leaks, high precision methods of manufacturing are often applied to produce hydraulic components. This, in turn, increases component costs. Pneumatics  in Dawson Creek can handle leaks because air leakage does not cause environmental damage. Instead, the air is released into the atmosphere. In addition, even the smallest leakage does not cause a drastic drop in pressure. Consequently, the system will still have the capacity to perform its operations.

Since pneumatic devices are air-based, they employ a less complex design and are developed with more inexpensive materials.

Areas of intermittent power

Hydraulic systems will immediately stop functioning the moment there is a power failure, which can prove catastrophic for some industries. If you consider the glass industries, for instance, liquid glass may begin to solidify in the equipment, which can end up destroying it. The same applies to the food industries that deal with semi-solid food products. Pneumatics have a reservoir of compressed air. In case there is a power failure, the reservoir powers up the system.

Response Time

The response time is the time it takes the system to execute a given function. In a pneumatic system, the compressor takes time to fully compress gasses. Consequently, the response time is high while the hydraulic systems develop working pressure the moment power is transferred to the pump.

Lifting Capacity

Pneumatic devices cannot be relied on to lift heavier capacity loads, as their operating pressure is not that high.

Wearing out

The pneumatic devices wear out more quickly, compared to the hydraulic devices, because the latter self lubricates. Note that the air used to power pneumatic devices is dry and moisture-free. However, lubricants or oil have to be added to reduce the effects of friction.

The main disadvantage of pneumatics is that the systems cannot be used for tasks that require high working pressures. Nevertheless, engineers are seeking solutions using modern technology with the aim of addressing this problem to allow for the execution of heavier engineering tasks using pneumatic systems. Although it only applies to lower magnitudes of mechanical and engineering tasks, pneumatic systems are a better suited and more viable solution than their hydraulic counterparts.
