  • 3 Reasons to Think About A Preventative Maintenance Plan

    Preventative Maintenance is a crucial element of almost all applications. Especially when that application is the cornerstone of the company’s profit flow. Disruptions and downtime can be extremely expensive and riddled with disaster. The good news is that a majority that the proper preventative maintenance strategy can eliminate downtime and profit loss.

    Efficiency

    When you have a plan for handling errors and problems in production you can perform quick turn around that keeps your production flow going. This efficiency also includes your personnel ability to work on more important things instead of scrambling to get something fixed. Attempting to fix a problem without a plan can take considerably more time than you think.

    Reduced Costs

    Ordering parts in a rush can incur larger shipping costs and that’s if you even order the right part. Waiting for a problem to appear before planning to fix it can mean an overlap in application knowledge and require your personnel to make decisions, under stress, about areas that they aren’t prepared to make. If you have the product on the shelf with an understanding across personnel as to what happens during downtime can really affect the bottom line.

    Value

    A preventative maintenance plan means you are actively paying attention to your systems and any potential weaknesses. This adds value by extending the life of your machines instead of letting them just kind of ‘break if they break’. This wastes company resources through both products and personnel. Trained staff is a positive investment overall.




  • Types of Hydraulic Fluids

    kyhf

    Petroleum Based

    Petroleum based fluids are by far the most popular and widely used fluids in hydraulic systems today. It’s popularity can be attributed to its economical pricing and its above average lubricity. Another strong point for petroleum-based fluids are that they have low toxicity levels. Petroleum based fluids can refer to either straight oil or an oil that’s mixed with assorted additives.

    Fire Resistant Fluids

    These fluids are comprised of a high content of noncombustible material, thus giving them their fire resistant ability. These fluids are best used in applications where a host failure or bust could lead to a potentially flammable situation. These fluids are typically divided into two categories Phosphate Esters and High Water Based Fluids.

    HFD Fluids

    HFD fluids are traditional synthetic products that typically don’t contain either water or petroleum. The most common HFD fluid is polyol ester because of its wide range of compatibility with most system materials and it’s amazing fluid performance. HFD tend to be more environmentally friendly that the petroleum and fire resistant fluids because of the absence of certain additives.

    Biodegradable

    Leaks and accidents can happen at any time and run the risk of hydraulic fluids contaminating the surrounding environment. This is especially as issue with applications near water sources and fragile ecosystems. Biodegradable hydraulic fluids have seen much popularity in the last few years due to the increase regulations around pollution and contamination. Common types of oils are typically vegetable oils and synthetic oils. If you are switching over to a biodegradable fluid from a petroleum based or fire resistant fluid, it’s important to verify that your components are designed to use these fluids.




  • 3 Killer Tips For Hydraulic Filter Storage

    hydraulic filter storage


    1. Filters must be completely sealed during storage

    Otherwise you run the risk of outside contaminants on what should be a brand new clean filter. Metal shelving can cause condensation to form on filters if sitting directly on metal, causing the filter to degrade and rust over time, rendering it useless.

    2. Always handle filters with the utmost care

    Especially if they are not in a box or sealed up. This also pertains to the transportation of filters to and from the job site. Never let filters roll around in the bed or floorboard of a truck.

    3. Utilize the ‘FIFO’ methodology when using filters

    FIFO stands for ‘First In First Out’ , it will serve you well to always use the older inventory first. Make sure filter boxes or containers are properly labeled with dates and information. If you have to pull the filter out every time to see if it is the one you need you are actively increasing the chances of that filter becoming contaminated.




  • 5 Common Ways Hydraulic Systems Get Contaminated

    Hydraulic Contamination

    In order to understand hydraulic system contamination, you have to go to the oil source. Even new oil straight from the shipping container is going to have contamination that is beyond the acceptable level that’s efficient for more hydraulic systems. It’s always a safe bet to consider oil to never be clean until you have filtered it. Contamination is a sly dog and the ways it can spoil seemingly clean oil is almost endless. Your system’s efficiency is on the line when it comes to contamination so be vigilant.

    1. New Fluid

    Most fluid and oil is ready for your system when it first arrives at location. It needs to be filtered and inspected before being introduced into your hydraulic system to prevent any traveling contaminants from infiltrating.

    2. Built-In

    Beware of contamination the gets introduced into a hydraulic system when assembling and testing new components. Whenever you add something new to a system keep in mind that it could be bringing its own foreign contaminants to the mix.

    3. Biological Growth

    Water is an integral element to just about all life on Earth and when it is ever present in the fluids coursing through your system there is always a chance that some biological growth can occur. Keep this in mind especially if you used fluid that contains high water amounts.

    4. Operational & Maintenance Related

    It’s important to consider the amount of contaminants that are involved with standard maintenance procedure. Pumps and motors can corrode over time and introduce contamination into your fluid slowly but can really cause severe damage if not monitored. Maintenance and efficiency should go hand in hand.

    5. Component Degradation & Replacement

    Overtime much of the rubber and elastomer components used in your system will start to degrade. When this degradation occurs there is a strong possibility of your fluid becoming contaminated with stray particles. Another contamination pivot point here is to make sure that when you are replacing a degraded/fault component that you thoroughly clean the conductor lines.




  • Selecting the Right Hydraulic Filter

    Filter Selection Guide

    Contaminants are the enemy of hydraulic circuits in applications worldwide. Inefficiency and downtime are the two most costly repercussions caused by a variety of contaminants, often resulting in excessive repair. The most important defense against inefficiency and downtime is the protection of the hydraulic circuits more sensitive components; this is the path to effective contamination control.

    How do you know which housing style or filter is the best for protecting your systems and equipment?


    Here are some steps to help you identify the correct parts for efficient contamination control.

    1.Determine Operating Pressure and Flow Rate

    Identify the most critical component in you systems hydraulic operating environment. Now think of two factors that are critical to keeping the component performing properly. Ex. Nominal and Maximum Operating Pressure or Nominal and Maximum Flow Rate

    2.Select Filter-Housing Model

    Donaldson Filters has a great filter selection guide that can help you identify exactly what meets your requirements.

    3.Consider Application Factors

    Once you identify the appropriate housing and filters you must take into consideration others factors that play into the components maintenance and protection

    4.Choose the Appropriate Accessories

    There are all types of different filter accessories that can help you in your contamination control efforts and prolong the life of your filters. Breathers, suction strainers, or gauges are all important parts of the overall system.

    5.On-Going Contamination Control Practices

    Contamination control is an ongoing process and requires routine checks and balances to maintain the components. Regular fluid analysis help monitor fluid contamination and condition.
