In the following few months we intent giving you a few tips to save money and downtime on your hydraulic equipment. We won’t be getting technical, just pointing you in a direction. The oil in a hydraulic system is possibly the most ignored component and it’s one of the most critical. It’s the oil that transfers the power as well as lubricating and cooling every component. Ok, It does a lot more than that but for now lets just look at maximizing the life of your oil which in turn will increase the life of every component in your system. One quick point, CLEANLINESS, CLEANLINESS, CLEANLINESS. Sorry, just had to say that. Next big one, TEMPERATURE. Oil today contains a myriad of additives and heat breaks them and the lubricity of oil down. From the simple graph below you will see that between 40 and 60 degrees centigrade is the optimal oil temperature giving you maximum oil life. For every increase of 8 degrees you effectively half the life of your oil so by the time you get to 85 degrees centigrade your oil life is 1/8 of what it is at 60 degrees centigrade. Checking oil temperature is easy and only takes a few seconds. Monitoring temperatures regularly will save you loads of money and downtime. If you want to know more or have a system that is running hot please call us and we will be only to glad to help.

The simplest way to start saving costs in hydraulics is to look after your oil. We tend not to think of oil as part of a hydraulic system but, as a cost, it is a major component. At the same time 90% of all hydraulic failures can be attributed to something that shouldn’t have been in the oil in the first place. So is it worth going to the effort of saving oil?? Consider this: •A leaking fitting that drips once every 10 seconds (and that’s a slow leak) will drip out about 180 liters of oil a year (do the math). That’s nearly R4000 a year at today’s prices. •As per my earlier article, if your oil temperature is 68 degrees you half it’s life, at 76 degrees it will only last ¼ the time. Consider your tank size and work out what that costs you. •Keep your oil “dry”. Water in oil will cause extensive damage to the whole system and anything more than a teaspoon full of water in 20 liters of oil will cause mechanical damage.

•Dirt, the nemesis of hydraulics is carried through your system by the oil. Dirt converts oil to grinding paste. Any and every particle of dirt in your oil will travel through your entire hydraulic system about 20 times every hour. That has got to hurt.

So, the easy way to save oil and money is to •Keep it in •Keep it cool •Keep it dry •Keep it clean

Relief valves are a very dangerous necessity in a hydraulic system. Often called safety relief valves because they set the maximum safe working pressure, they have one necessary dangerous flaw. They are adjustable and therein lies the problem, they get adjusted. If your system was working fine last week and it isn’t now, the last thing you should be doing is adjusting the relief valve, yet most technicians are quick to whip out an Allen key and “give it a turn” to see if that solves the problem. Relief valves either work or they don’t work. If they don’t work, fiddling with the setting won’t make them work. What more than likely will happen is the technician will find the real problem a few hours later and forget he fiddled with the relief valve first resulting in potentially high pressures and catastrophical failure. A year ago we supplied a customer with a R15000 pump. His technician fitted it to the machine, started up . . . . . . . and blew up the pump. We immediately got the blame for supplying a faulty unit. I went out to the customer with a new pump, fitted it and a flow tester into the system. The flow tester gave me the ability to gradually increase the pressure until the relief valve blew off. Normal operating pressure of the machine was 150 Bar but at 250 Bar the relieve valve was still firmly closed. I showed this to the customer prior to backing the relief valve off to 150 Bar. We will never know what the valve was set to but fortunately the operator told us that their own technician had “turned that thing” to see if he could get it to work. The customer ended up paying nearly R17000 more than he should have because of one simple error.
