Hydraulic Press Safety and the Role of Pressure Switches

Hydraulic systems have various functions and applications, from industrial manufacturing to robotics and steel processing. They are analogous to pneumatics, which easily compressible gas to perform tasks. Hydraulic systems, on the other hand, use incompressible liquids as their fluid rather than compressible gases. Repetition–hydraulic systems are industry preferred low-cost, efficient ways to generate movement. 

To use these systems effectively, workers must understand the risks and potential hazards associated with hydraulics. Your employees could be in danger if they are unaware of the extreme fluid pressure, maintenance, and heavy workload. Fortunately, various safety precautions reduce the risk of injury or death significantly. 

Our hydraulics safety precautions guide will cover common hazards and precautions to keep you and your employees safe.

How Does A Hydraulic Press Work? 

Hydraulic press systems use a pump that pushes fluid throughout the machine to create energy in its simplest form. The fluid then enters a set of valves and flows to the cylinder, where hydraulic power changes back to mechanical energy. When necessary, these valves also help control the liquid’s movement and relieve pressure.

There are several types of hydraulic press systems on the market. Depending on your application or industrial setting, you will most likely use one of the following: 

• An Arbor press uses a narrow range to support the disposal, seating stamping, manufacturing, and repairing of equipment.
• An H Frame press (or four-column) is the standard in many businesses for its versatility. They are used to straighten, bend, shape, stamp, or cut metal objects.
• C Frame press systems are relatively smaller than H frames but maintain similar utility and flexibility in a light yet compact build.
• Custom presses provide solutions for a company’s personal needs and specifications.
• Press brakes clamp and bend sheet metal and plate material.

Although these machines make work easy and productive, they are still highly dangerous and can break down if not properly maintained.

The Most Common Reasons for Hydraulic System Failure 

Hydraulic systems can fail, whether with a custom press or a four-column frame. After a while, presses may begin to show wear and tear in critical areas. Many damages, however, can be avoided with regular maintenance checks and care. 

Let's look at five common causes of hydraulic system failure and electric and hydraulic tool safety practices. 

1. Poor Maintenance 

Maintenance is essential for keeping your hydraulic press operating at peak efficiency. Here are some components and functions to consider during the evaluation:

• Hoses 
• Oil leaks
• Ram Speed
• Wire tightness
• Oil temperature
• Electrical Fuses
• Solenoids and relays
• Oil level and particle count
• Hydraulic fittings for tightness
• Coupling and insert for tightness
• Pressure adjustment for the full range

If these functions are not maintained, presses will fail at a high cost. Daily inspection and standard maintenance will extend its service life and, most importantly, keep workers safe. 

2. Leaks through pinholes 

Pinhole leaks can cause toxic fluid leakage at speeds of up to 600 feet per second. Although they may be difficult to spot at first, pressure switch technology will alert the user of a leak before any visible signs appear. To ensure proper utility, it is still necessary to inspect your hoses during the inspection process. 

3. Inadequate Couplings 

Improper coupling of low- and high-pressure systems is another dangerous hazard. It is never a good idea for you or your employees to connect a high-pressure pump to a low-pressure system because component, hose, or fitting ruptures can occur. 

4. Removal or modification of a component 

Servicing a hydraulic system while the machine engine is running is very likely to result in bodily harm or death. Remove no components while the working units are resting on the ground, safety stands, or blocks; always turn off the engine when doing so. 

5. A Low and High-Pressure Warning 

Workers may be exposed to three types of hazards when removing or adjusting components without first releasing the pressure:

• Burns from hot, high-pressure fluid
• Bruises, cuts, or abrasions from flailing hydraulic lines
• Hydraulic injection of fluid into the skin 

To avoid these common mistakes, educate yourself on hydraulic press systems and carefully follow instructions. 

With CCS pressure switches, you can protect your hydraulic equipment, personnel and operations. 

You and your team can improve productivity, quality, and employee morale by learning more about hydraulic safety precautions.

Pressure and Temperature Switches for Water and Wastewater Treatment

Water treatment occurs before the water reaches a business or community, whereas wastewater treatment occurs after the business or community uses the water. 

Water treatment has higher pollution control standards and necessitates more costly treatment procedures such as chemical coagulation and flocculation and the use of granular activated carbon filters. However, contaminant levels are usually low and predictable because most water goes through water treatment from a natural source (such as a river). 

After a business or community uses water, it becomes wastewater and is in most cases returned to the environment after treatment. The treatment standards are typically lower than those used in drinking water facilities. Unlike water treatment, wastewater treatment does not usually take place in a single location. Certain enterprises with highly dirty wastewater must have their treatment system before delivering it to community wastewater treatment plants. 

Temperature and pressure switches apply to many water and wastewater treatment processes at practically every stage. Water flow sensors and switches enable pump vibration control, handle slurry environments, monitor pressure spikes, and endure corrosive media, and address the application difficulties of water and wastewater treatment systems. CCS pressure switches are resilient to pump impulses, pressure spikes, and hammering thanks to Belleville disc spring technology, tight construction, and durable assembly.

Trace Mechanism or Snap-Action - What's in Your Pressure Switch?

Complex systems and processes can use either a trace or a snap-action switch to provide an electrical response to the rise or fall in pressure or temperature. System pressures and temperatures rarely follow a smooth pattern of rising and falling. The switches used to track and control the system are subject to those fluctuations, as illustrated in the following graph.

Deciding whether to use a snap-action design is critical to your switch's efficiency, accuracy, and longevity. This video will cover key differences between each device and how they apply to the switch operation. 

What is the difference between a trace switch and a snap-action switch? 

In their simplest form, pressure switches have two components: a mechanism that reacts to a change in pressure and an electrical switch (sometimes called a micro-switch). When the pressure or temperature reaches a certain level (the set-point), the mechanism moves to actuate the switch. This process can either allow or stop currents in the control circuit.

What is a Trace Mechanism?

Common alternative mechanisms to snap-action devices are trace designs, also known as spring-based mechanisms. Switches with a trace mechanism follow or trace the exact pattern of pressure or temperature changes. These trace devices can include a helical spring or spiral spring, a Bourdon tube, or bellows in their mechanism. 

A spring-based trace switch mimics the pattern of changes even after reaching set-point. The mechanism and micro-switch are in constant motion when there are changes in pressure in the system. This continual movement wears on the components of the instrument and electrical switch. And over time, it causes the set-point to drift from the original setting to fatigue and the mechanism's failure. 

What is a Snap-action Mechanism?

Unlike trace switches, a snap-action mechanism remains inactive during system pressure and temperature changes. Upon reaching the set-point, the snap-acting disc immediately reacts to activate the switch. Eliminating this continuous motion until the point of activation and deactivation can reduce the mechanism and switch element wear, extending its duration. 

Snap-action designs are the premium type of switch on the market. They can perform 10 million cycles or more due to the components' low fatigue, including the micro-switch. 

While trace and snap-action pressure and temperature switches may perform the same function, understanding the difference in their movement and precision explains why quality-minded people prefer snap-action controls over other designs. Trace designs fatigue the mechanism and the internal micro-switch through constant motion. Snap-action switches use an innovative snap-action disc spring that remains still despite fluctuations until action is needed. 

CCS pioneered the Dual-Snap, snap-action disc used to provide accurate and reliable pressure and temperature measurement under every operation. For more information on CCS pressure and temperature switches in Virginia, contact Automatic Controls of Virginia.
