Oil maintenance is a key factor in ensuring the smooth operation of hydraulic systems and plants. Contaminants in the fluid can have serious effects. From fluid analysis and cleaning to continuous condition monitoring during operation, HANSA-FLEX fluid experts support you at every stage of oil maintenance for your systems and machines.
You can prevent damage and downtime by taking advantage of the know-how of HANSA-FLEX fluid experts
Comprehensive oil analysis
Whether mobile or stationary hydraulics: oil analysis forms the basis for optimum oil care. Expensive downtimes and major replacements can only be avoided if problems with the fluid are detected in good time and measures taken to rectify them. For this reason, the HANSA-FLEX Fluid Service offers comprehensive oil analyses on site and in the laboratory.
Efficient oil cleaning
By regularly filtering your oil, you can ensure that your hydraulic systems run smoothly for longer. Solid and liquid contaminants cause wear, increase abrasion and promote corrosion. HANSA-FLEX fluid experts clean your oil professionally and find the perfect filter solutions for your area of application.
Oil cleaning, detecting damage, system optimisation: Fluid care is complex, requiring a lot of knowledge and experience. What should you look for when dealing with hydraulic oil? Here is a list of the ten most important points: from the selection of a suitable hydraulic oil right up to using sensors to continuously monitor it.
The quality and cleanliness of the hydraulic oil used are crucial parameters for the operational reliability, service life and cost-effective operation of hydraulic systems. The recommendations of qualified fluid experts, oil manufacturers or dealers can be very valuable in this respect.
To remove any foreign matter that may have entered the system during installation, every hydraulic system should be flushed before it is used for the first time and then every time it is put into service. In this way you ensure that your system runs perfectly right from the start.
You have just bought some fresh oil. Can you assume that it meets the cleanliness requirements? This could be a big mistake. It is not unusual for oil to be supplied in an unclean state because oils are often not passed through a fine-pored filter during the manufacturing or filling process. Therefore, always make sure that fresh oil is filtered before you put it into your system.
Mixing different hydraulic fluids often results in a dramatic deterioration of their physical properties. You should always avoid mixing different oils because no oil combination is 100% trouble-free. This applies to fluids with the same classification and to products with different viscosities.
Contamination of the oil with solids such as dust or metal particles or sealing material is one of the most frequent causes of damage and can lead to increased wear of the installed components. Contamination of the oil with air or water can cause corrosion or cavitation. To avoid these harmful effects, suitable filtering solutions should be used and the system parameters optimised.
Have regular oil analyses carried out in the laboratory or on site so that the oils used in your hydraulic systems permanently achieve a high quality standard. In this way you ensure a long service life for your systems and avoid expensive failures and long downtimes.
You can use various filter systems such as suction and return filters to filter your oil. The filter elements should be replaced at frequent intervals. Mobile filter systems, such as bypass filter systems, can also be hired from HANSA-FLEX.
A very high operating or ambient temperature reduces the performance of the hydraulic oil. High temperatures can, among other things, lead to the formation of acid and a high rate of wear of the components. It is also helpful to make sure the tank contains the correct volume of oil and to use an oil cooler.
Are you installing a new hydraulic system? Pay attention to cleanliness to prevent foreign particles from entering the system. The system should be thoroughly flushed clean before being put into service.
Oil condition sensors help you to continuously monitor your hydraulic systems and drives. Your advantages: Malfunctions during operation can be detected quickly and the risks of failure can be analysed.
The 3 Most Important Facts About Handling Hydraulic Oil
Hydraulic oil has to withstand high stresses. The standard for pressure fluids, DIN 51524, specifies the minimum requirements for hydraulic fluids. Other requirements are:
More than just changing the oil
Fluid management involves more than just regular oil changes. Oil cleaning and analyses can help to prevent failures and downtimes. If a hydraulic system is carefully designed to achieve a certain performance, the requirements for the components used, such as the fluid and filtration solutions, are particularly high. By obtaining professional advice from fluid experts, you can lay the foundations for:
