The hydraulic pump is the power behind your hydraulic system. Therefore, you should understand what factors affect your hydraulic system's design, efficiency, and operation. Here are four hydraulic pump problems that necessitate a hydraulic pump rebuild.
1. Excessive Noise and Vibration
Excessive noise and vibration problems arise in pumps due to cavitation. In addition, cavitation causes damage to the pump and other parts of your machinery. Cavitation occurs due to air in the system. Air enters a hydraulic system when there is leakage or during maintenance or repairs. If you don't remove the air, it enters the pump.
The noise and vibrations occur when cavitation bubbles collapse. Cavitation results in pump failure if left unchecked. The issue can also emanate from low flow rates, low liquid levels, or clogged lines and filters.
Hydraulic pump noise can also result from worn bearings or gears or poor oil quality. Excessive noise and vibration call for immediate attention. Your hydraulic pump expert will undertake a hydraulic pump rebuild if the issues are severe.
2. Low Pump Pressure
The most common type of hydraulic pump problem is low pump pressure. There are a few possible reasons why this could happen. The first reason is due to damaged or worn-out parts. In other situations, there may be blockages in the hose that make it difficult for the fluid to travel to where it needs to go. The filter should also get cleaned or changed.
Severe and recurrent low-pressure issues will necessitate a hydraulic pump rebuild.
3. Oil Leakages
Another common sign there's a problem with your hydraulic pump is leaking seals. There could also be oil leaks along the shaft or around the pump's body if seals are improperly installed or damaged. You may even see air bubbles in the system or suction line if there's a leak in the seals. Leaks are a major concern since they can cause issues with the equipment and affect productivity.
4. High Hydraulic Fluid Temperatures
High hydraulic fluid temperatures can destroy your hydraulic pump. A few causes of high hydraulic fluid temperatures include:
Operating the pump at higher than normal pressures
Operating a system with a low hydraulic reservoir capacity
Operating a low capacity pump for an application
Operating your hydraulic pump using the wrong type of fluids in a system
Excessive heat occurs when you operate your hydraulic pump at higher than normal pressures. As a result, this heat causes premature wear and damage to the internal components of your hydraulic pump. If you want to extend the life of your hydraulic pump, operate it below its maximum recommended pressure.
In the case of hydraulic pump problems, seek hydraulic pump rebuild services. Hydraulic pumps need proper care to last as long as possible. If you address small problems before escalation, you'll save time and money. Also, undertake regular inspections to maintain maximum efficiency.Share
