Safety Hazards Associated With Hydraulic Press Operation

Hydraulic presses are essential tools in many manufacturing processes, yet they can also pose risks if not used properly.

One of the primary safety risks comes from taking apart or adjusting components without first releasing pressure. This puts workers at risk of burns from hot, high-pressure fluid; bruises, cuts or abrasions caused by flailing hydraulic lines; as well as injection of hydraulic fluid into skin tissue.

Overheating

Hydraulic presses, whether used to compact food, make appliances or manufacture car parts, are powerful machines that must be operated carefully. Excess heat during hydraulic press operation can result in serious injuries as well as damage to both people and equipment itself.

Hydraulic system overheating can be caused by a variety of causes. For instance, the temperature of hydraulic fluid within a system can significantly impact its viscosity.

Cold temperatures can increase the viscosity of fluid, while hot temperatures decrease it. If this situation is not addressed promptly, permanent damage to your hydraulic system could ensue.

Oil Leaks

Hydraulic presses are an integral part of many industries, yet they also present a serious safety hazard to operators and those nearby.

Oil leaks can quickly cause extensive property damage and even injuries. That is why it is so essential to regularly inspect your hydraulic press for signs of any potential issues.

Leaks can be caused by an overfilled oil reservoir, dirty check balls or damaged piston packing. Inspect these areas regularly and replace seals as necessary to avoid further damage.

Vibration

Hydraulic presses are essential pieces of machinery in many industries. Not only do they serve a range of specialized and general purposes, but their potential hazards to operators must also be taken into consideration.

Vibration is a physical phenomenon wherein a mass moves back and forth on its own, but eventually returns to its original equilibrium position due to an external force dislodging it from that initial position.

Vibration in a machine or component may be caused by loose fitting, eccentricity, imbalance or other causes. Vibration analysis is the best way to identify these causes and prevent future vibrations from occurring.

Slippage

Hydraulic presses can be hazardous if not properly guarded and maintained, particularly those using high-speed rams.

Due to their potential trajectory, these parts can become projectiles that could strike an operator or other person nearby the machine.

Slippage during hydraulic press operation is a serious danger if the ram isn't securely fastened or an operator places their hand or fingers under or near the bending point of the ram.

Amputations or other injuries may result from this situation. Therefore, safety measures like light curtains that shield hands and other parts of the body should be implemented for enhanced protection.

Falls

Hydraulic presses are a widely-used tool in manufacturing. They exert substantial compressive force onto billets, shaping them into desired designs and forms.

The press utilizes a mechanical system to transmit hydraulic pressure between two cylinders: one smaller cylinder and one larger one. A small force (F1) is applied to the smaller cylinder, while a much greater force (F2) is generated by the larger cylinder.

When material is placed between two plates and activated with a limit switch, hydraulic pressure is transferred to the workpiece. It's essential to adjust the limit switch properly in order to prevent excessive strain on your workpiece or machine malfunction.

Fire

One of the greatest hazards involved with hydraulic press operation is fire. Hot surfaces within the system, combined with oil sprayed onto them, can ignite and create a torch-like exploding fire that could rapidly damage or destroy equipment.

To reduce this hazard, the most efficient solution is to substitute mineral oil with less flammable fluids. Fortunately, there are numerous such alternatives available.
