The most critical requisite of running any piece of reliable hydraulic equipment is to keep it clean. Unfortunately, extreme pressure systems provide a constant battleground to fight against potential system contamination by particles, dirt, dust and other matter that can all get into the works. Keeping fittings, pipes, valves, filters and any other components clean is an absolute must if you are looking to run your machine efficiently and with optimised output. Here are or tips on how to address the cleanliness issue around hydraulic equipment: · Filters need to be replaced regularly, with fluid replaced annually at minimum. The latter should be done for the entire system, including reservoirs. · Know that pipes need to have the minimum count of bends. Fittings should also be minimal and securely fastened in addition to being clean. Iron pipes are no longer recommended due to having particles which are likely to dislodge and contaminate. · Ideally you would consult with your engineer regarding best pipe or tubing for your specific machinery set up. By showing them the schematic they should be able to advise on what is required to run your system at maximum efficiency. In our experience, we believe that hydraulic piston pumps are preferable to gear and vane pumps. We find that they usually operate over a longer lifespan, even whilst being at higher pressure. Fortunately, the piston pump also comes with another advantage; it actually vibrates far less and sometimes not at all. If you are unfortunate enough to experience one, there are occasions when a pump failure has been related to improper assembly by the manufacturer. It’s important to capture failure data in order to claim a warranty, where a warranty is due. If you have a full in-house machine shop, always ask whether they can fix up the broken part as opposed to having to order in a new part. To be certain that you are buying components that are quality, be sure to ask whether they are tested: · Both dynamically and statically · To produce full testing certificates and test reports Although the piston pump may cost a little more than the gear and vane pumps, over a long period of time, they will cost less during the lifetime of the equipment.
