The essential parts of hydraulic systems that produce liquid flow are hydraulic pumps, which transform mechanical energy into hydraulic or fluid energy. Premature breakdown and expensive repairs can be avoided with planned maintenance and routine inspection for indications of failure.
This blog post will discuss the typical indicators of hydraulic pump failure and factors to take into account when deciding between repairs and a full replacement.
Indices of Inadequate Performance:
1. Leaks Within
2. External Disclosures
3. Water-Based Pollution
4. The pump is making loud noises
5. Decreased System Efficiency
Interior or external leaks are the most obvious indicators of impending breakdown. A damaged, pinched, or ripped O-ring, seal, spacer, or snap ring is frequently the source of these. On the other hand, internal sub-components that might have broken or cracked during operation could also be to blame.
Requiring frequent replacements of O-rings, seals, and spacers may indicate that the drive shaft is misaligned, offset, or slightly curved. Fluid contamination and loud noises or skipping of the hydraulic pump are other indicators of failure. Finally, a broken pump can make your hydraulic system operate less efficiently overall. Your pump might need to be repaired or replaced if you've observed a drop in performance.
By doing regular visual and audio inspections, you can prevent a pump or entire system failure before it becomes worse. Here are a few methods for resolving typical pump problems:
Both are really obvious. The worst-case scenario will be an increase in leakage or a decrease in oil pressure. To make sure air isn't getting into the pump, check the oil level. To stop these leaks, you might have to replace the gaskets, seals, and O-rings after assessing their condition. Once more, a break or fracture of one or more internal subcomponents could be indicated by these occurring repeatedly.
Stop the system at away if you see that the pressure in your hydraulic system has decreased or is nonexistent. It can be a sign of low oil levels, internal mechanical problems, a clogged intake valve, or even internal corrosion that is interfering with the drive shaft/piston rod action.
Cavitation is the formation of gas bubbles inside the pump and might be indicated by a clunking or rattling sound. The reason for the appearance of these bubbles is that the pump isn't getting enough oil to run well. The hydraulic pump becomes filled with bubbles that eventually burst, allowing air to enter the system. As a result, the system's pressure will frequently noticeably drop.
Installing suction lines, lowering the flow rate, or raising the fluid level in the reservoir could all be necessary to address cavitation problems.
It is possible to seriously harm the pump, as well as its parts and subcomponents, by going over the pressure levels and ratings specified by the pump manufacturer. Oil will be redirected back into the pump through a broken, damaged, or malfunctioning check valve, damaging the hoses, seals, and internal parts of the apparatus. Overpressurization can harm the pump and the hydraulic system as a whole, so it's important to monitor pressure levels and never go above the OEM-specified pressure rating.
Water or fluid contamination is indicated by oil that appears off-white or milky. The contamination can harm the internal parts of the pump, such as the valve plate, driveshaft/piston, bearings, and cylinder block, so you should immediately cut off the hydraulic system. Particles and contaminants can wear down or scrape the internal components of the pump, slowing it down or causing too much friction between the mating surfaces of the components.
Fluid that has become contaminated can quickly enter the system and may be challenging to clean up. In the event of contamination, the system must be completely flushed and fresh fluid added. To lower the chance of contamination in the future, it is advised that you install filters on your pump.
Most of the time, hydraulic pumps can be repaired. The majority of the time, repairing a hydraulic pump is taking it apart, figuring out what's wrong, swapping out any broken parts, and then cycling the pump before using it again.
It is quicker to repair a pump than to purchase an OEM replacement. You need to find out if the cost of the repair is half or more than the cost of a new pump. The least priced alternative is preferable as most pump problems are fixable.
Regrettably, there are no hard and fast guidelines when it comes to hydraulic pump repair costs. Every circumstance and cause of failure is unique. The severity of the issue, the length of time needed to remove the pump, and the number of parts that need to be cleaned or replaced all affect how much a hydraulic pump repair will cost.
As a point of comparison, a brand-new cylinder block can cost between $100 and $700, while gaskets and O-rings can be purchased for $5 to $10 and individual bearings for $8. From then, the issue is how many internal parts require replacement in addition to labour expenses.
Long service lives in the field are built into hydraulic pumps. Usually, a hydraulic pump replacement is only necessary when the pump is getting close to the end of its anticipated life. The protection of the entire hydraulic system is another justification for pump replacement. The pump needs to be replaced if it keeps breaking that system.
When the cost of replacement is lower than that of repair, it is another circumstance in which replacement is preferable. This frequently occurs when there are too many components that require refurbishment and repair, and the cost of the repairs is more than the cost of replacing them.
The type of pump that needs to be changed, its purpose, and the hydraulic system it works in all affect how much a replacement will cost. Even with these exceptions, you should budget between $1,500 and $4,000 for a replacement pump; OEM pumps are more costly and have longer lead times.
It may take some time to wait for a direct OEM replacement if your pump is malfunctioning or has already failed. You can cut downtime by investing in a refurbished or OEM-equivalent pump. In addition, the majority of remanufactured pumps are significantly less expensive than OEM replacements and go through rigorous testing to guarantee quality.
Make sure the provider you choose for remanufactured pumps offers guarantees and rigorously tests the pumps to guarantee they match or surpass OEM requirements.
In the US, Xincan is a reputable producer of aftermarket hydraulic piston pumps and motors for Vickers/Eaton and Rexroth A10-V-30/-31.Every pump we produce is covered by an 18-month warranty and is rigorously tested to make sure it meets or exceeds the original OEM specifications.
Along with offering premium replacement parts including O-rings, cylinder blocks, seal kits, and compensators, we also repair and rebuild all varieties of Rexroth and Vickers/Eaton parts.
