Some hydraulic pump defects can be fixed without calling a technician for help. This article discusses some easy solutions that you can try in case the hydraulic pump of your equipment begins making excessive noise.
Clean the Strainer
Hydraulic pumps can start vibrating excessively or making a lot of noise when the suction strainer on the inlet side is dirty. You should therefore check this strainer and confirm whether it is clean or dirty. Replace or clean that strainer depending on the manufacturer's recommendations. For instance, some strainers can only be replaced once they become dirty.
Tighten the Suction Components
Hydraulic pump noise may also be due to a loose component, such as the suction line, on the suction side of that pump. It is advisable to tighten all the components on the suction side before you think of calling an expert for help. Fixing that looseness may resolve the problem that the pump was having.
Restore Fluid Levels
Pump noise or vibration could also be a result of insufficient hydraulic fluid. Top up the fluid to the recommended level. You can then observe the pump during a duty cycle in order to see how the level of the fluid changes as the pump functions. Add more fluid in case you notice that the level drops drastically as the pump is operating. This step is especially helpful in case your hydraulic system has a large actuator.
Check the Type of Oil
The use of the wrong type of hydraulic fluid can also cause a pump to be noisy or vibrate excessively. For example, hydraulic fluid that is of low viscosity may be unable to prevent metal-on-metal contact in the pump. Consequently, noise will be produced as metal components rub against each other as the pump is working. Check the manual of the pump and change the hydraulic fluid to the type that is recommended by the pump manufacturer. This tip is important if you use different types of hydraulic fluids for the different seasons of the year.
Check the Pump's Installation
Sometimes, a hydraulic pump may vibrate or make excessive noise due to changes in its installation settings. For example, the mounts anchoring the pump may be worn or loose. Check the pump's anchorage and tighten or replace any loose/worn couplers or bolts.
You will reduce the frequency of conducting costly hydraulic pump repairs if you can quickly fix the minor issues above as soon as that pump starts making excessive noise or vibrating abnormally. Call pump repair experts in case the suggestions above don't fix the problem with your hydraulic pumps.
