If you own a hydraulic system, you may already know that ‘heat’ is one of the most notorious causes of many big and small issues. Overheating is one of the most common causes of issues with your hydraulic equipment, no matter how well-designed it is. Although you can make a few changes that can help you to reduce the damage caused by overheating, it is probably impossible to completely eliminate the possibility of excessive heating for any hydraulic equipment. Firstly, it is important to learn what causes excessive heat to your equipment. You also need to understand how you can possibly reduce the damage it causes to the components of your hydraulics equipment.
With a few precautions, you can increase the expectancy of your hydraulics equipment and make sure that you get the best out of them. You may be surprised to know but reducing the heat of your hydraulics equipment can be as easy as a simple adjustment of a valve to perform a complete heat load analysis and introducing the right amounts of air-oil or water-oil cooling system to balance the problem.
Here are some common causes of hydraulics overheating
One of the most common complaints of many hydraulics equipment owners is that their hydraulics equipment has started heating all of a sudden after functioning efficiently for a long period of time. Many Toronto based hydraulics repair service professionals believe that these problems usually needs a minor adjustment. In pressure compensated variable volume pump systems, users often adjust the pump compensator which increases the pressure in the pump. Adjusting the pump compensator to move past the main relief valve setting results in the pump coming on stroke and the dumped waste flow is set at maximum pressure setting, resulting in heating up of the system.
Another common complaint is that users observe that machine is getting heated although nothing is moving. Pressure drop in a machine can also cause significant heat especially when the components are not sized properly.
When the machine needs to exert additional pressure to push the oil through the valves, pipes, hoses, elbows, bends, and filters, this pressure is reflected on the machine in the form of heat. Simply upsizing your components and reducing the bends in your plumbing can improve the situation. If it is not possible to avoid radical bends, consider increasing the size of your hoses and fittings. This way you can increase your capacity without exerting excessive pressure on the equipment.
If you can’t change your hydraulics components, talk to your local hydraulic pump repair store. In most probability, they will suggest you purchase an external cooler for your system. Instead of reducing the heat, the cooler helps to pull out the excess heat and maintain optimum temperature for your hydraulic equipment to function. Cooler selection is based on a lot of factors like heat load, type of system – industrial or mobile.
It can be tricky to find the right cause and remedy for your hydraulics equipment since overheating can be caused by a variety of reasons. It is best to approach a licensed, trained and qualified hydraulics services centre like S & T Hydraulics for the best advice and service.
