Hydraulic filters are a critical part of hydraulic systems. They help remove dirt and debris from fluids. This keeps machinery working well. Plasser makes these filters for things like track work and tool adjustments.
Several kinds of Plasser hydraulic filters are used in various machines. Each type is made to filter fluids in a special way depending on where it goes.
Inline filters
Inline filters sit right in the hydraulic hoses or pipes. They clean the fluid before it moves into pumps or motors. This protects those parts from getting damaged by particles. Plasser inline filters often have mesh or paper elements that catch dirt. They are regularly checked and cleaned or replaced to ensure the system gets filtered fluid.
Tank filters
Tank filters are mounted directly on the hydraulic oil reservoirs or tanks. Before fluid is drawn out for use, it passes through these filters. Plasser tank filters keep contaminants from entering hydraulic circuits. They usually have larger filter elements designed for heavy dirt loads. Regular maintenance is important to prevent buildup from causing blockages.
Return filters
Return filters are positioned where used hydraulic fluid returns to the oil tank or reservoir. As fluid cycles back, these filters remove sludge and particles accumulated during use. Plasser return filters often have high dirt-holding capacity elements that can be cleaned or swapped out. Keeping them serviced prevents dirt from recirculating and damaging components.
Pressure filters
Pressure filters are integrated into high-pressure areas of hydraulic systems, such as before pumps. They ensure no contaminants enter sensitive components under force. Plasser's pressure filters utilize fine mesh or paper media to catch tiny particles. Their location requires pressure-rated designs. Filters are routinely inspected to maintain proper hydraulic pressure away from machinery.
Off-line filters
Off-line filters are standalone systems that circulate tank oil through external filters regardless of whether the main hydraulics are running. Plasser's off-line units extend element life and reduce contaminants. They often have large filter housings with deep, easily accessible cartridges. Using these filters routinely can achieve lower overall dirt levels in the hydraulic system than using just inline or return types.
Key specifications
Hydraulic filters have important specs that determine how they function. Knowing the details helps users pick the right filter. Key specs include the filter element's micron rating, flow rate limits, and operating pressure range.
The element's micron rating shows how small particles get trapped. A 10-micron filter catches more dirt than a 20-micron one, but less fluid can flow through it. Filters with lower ratings work better for components needing extra protection. Return and tank filters often have higher microns since they catch settled dirt, not fine particles.
This hydraulic filter tends to have high flow rates to avoid backups in busy systems. Its design helps fluid move through quickly without resistance. Filters shouldn’t restrict fluid flow too much, or pressure builds up, causing problems.
The filter must withstand hydraulic pressure from pumps. Filters are rated anywhere from 100 to 3000 psi, depending on where they go. Areas with high-pressure work, like pumps and motors, need filters that can handle forces without breaking down.
Filter elements
The part of the filter that actually does the cleaning is the filter element. Elements trap all the little particles that could harm things. Common materials for these elements include mesh, paper, and synthetic fabrics.
Metal mesh elements are one type. They can be cleaned and reused, which makes them good for heavy dirt that builds up fast. People choose mesh for inline and return filters because it holds lots of grime.
Paper filter elements
Paper filter elements capture very tiny specks that metal can't catch. Plasser makes these paper elements for filters that protect sensitive parts like pumps and valves. However, paper gets full faster, so it must get changed often.
Synthetic fabrics
Synthetic fabrics are similar to paper but stronger. They withstand more force and pressure. THAT SYNTHETIC material also catches even smaller particles than regular fabric. Some of the toughest filters use super fine synthetic fibers to make filters last longer.
Assess contamination levels
Consider how clean or dirty the hydraulic fluid is expected to be. Systems that stir up more particles from working hard need filters with finer meshes to catch everything.
Match micron ratings
Filters come in different micron sizes, which measure how small particles are. Microns are like tiny measuring sticks. Pick a filter that has the right micron size for the parts it protects. Pumps and motors need filters with small ratings to catch the tiniest dirt. Return and tank filters can have bigger micron sizes since they trap larger settled particles.
Consider flow rates
Make sure the filter can handle enough hydraulic fluid without slowing things down. Each filter has a flow rate limit, and always match this to the machine's needs. A filter that slows fluid flow could cause pressure build-ups and damage.
Think about placement
The position also matters when choosing. Pick the right kind of filter for where it will go in the hydraulic system. Inline filters work best in one area, while return and tank filters are better suited for other sections.
Check the maintenance requirements
Maintenance is also essential. Consider how much filter care the crew can manage. Some need to be cleaned or changed more often than others. Select one that fits the available time and resources for upkeep.
Key maintenance tasks
Paying close attention to some basic care helps keep them in top shape for the work ahead.
The first step is staying on schedule with filter changes. Each one lists how long it can run before the element needs replacing. Don’t let it go too far - the machine could get damaged if dirt builds up. Catch this issue before it’s too late by looking at the gauge.
Inspect and clean regularly
Regularly checking the filter itself is simple. Just look it over to spot any serious damage. if there are signs of wear or tears, switch out that element fast. Some parts can be hosed off, but be careful - don’t use strong cleaners that could ruin the filter. soft brushes work better for delicate filters.
Monitor hydraulic fluid
The filter only does its job well if the fluid itself is cared for. Keep an eye on the oil level in the tank and top it off as needed. But make sure to use the correct type of fluid - refer to the manual if unsure. Dirty oil makes the filter work overtime, so plan on regular fluid changes too.
Check for leaks
Still, hydraulic filters under pressure, so any tiny leaks must be fixed right away. Get in the habit of looking for signs of seepage around filters and lines. Keep seals in good condition because worn ones cause leaks.
Professional servicing
Filters that get heavy use or are particularly critical should be serviced by the pros. The team can fully clean complex parts and make repairs that will extend its life. Any factory recalls on components should be addressed promptly too.
Here are some questions people often ask about Plasser hydraulic filters:
Q1:What do these hydraulic filters do?
A1: These elements remove tiny dirt and particles from the oil. This protects moving parts and keeps the system running smoothly.
Q2:Why are they important?
A2: They prevent wear and damage to expensive components. Without proper filtration, the oil could harm valves, pumps, and other parts.
Q3:Are there different kinds?
A3: Yes, there are inline filters, return filters, pressure filters, and more. They each serve specific roles within the hydraulic system.
Q4:How often should the filters be changed?
A4: It depends on usage, but common guidelines are between 500 to 1000 hours. Consulting the manual provides more tailored advice.
Q5:Can the elements be cleaned?
A5: Certain filters with metal mesh elements can be rinsed and reused. Others, like paper filters, need to be replaced completely.
Q6:What happens if a filter is clogged?
A6: Clogged filters can cause pressure builds, leading to potential damage. Regularly monitoring them is crucial for system health.
