How should hydraulic pumps be maintained to prevent failure?

Imagine you're in the middle of a crucial operation, pressures are at their highest and suddenly your hydraulic pump breaks down. Your work is interrupted, deadlines are compromised and the cost of repairs soars. Fortunately, there is a way to prevent common failures of hydraulic pumps and ensure optimum operation of these machines. Want to find out more? Find out in the rest of this article, the secrets to maintaining your hydraulic pumps and keeping them in top condition, ready to take on the toughest challenges.

What should you do to maintain your hydraulic pump ?

Whether you're a seasoned industrial professional or just a do-it-yourselfer, it's important to adopt the right practices to not only prevent your hydraulic equipment from breaking down, but also to repair it when it does.

The importance of regular maintenance of hydraulic pumps

L'importance of regular maintenance of hydraulic pumps cannot be underestimated, as this plays a crucial role in their smooth operation and optimum lifespan.

Indeed, this equipment is subjected to demanding working conditions, with high pressures and constant mechanical movements. Without proper maintenance, problems such as leaks, premature component wear and performance degradation can occur, leading to high repair costs and unwanted downtime.

By carrying out regular maintenance, you can detect and prevent potential problems before they become major ones, which is essential for maintaining the reliability and efficiency of hydraulic pumps.

In addition, regular maintenance optimises the energy efficiency of the pumps, contributing to long-term cost savings.

Basically, when you devote time and resources to the regular maintenance of hydraulic pumps, you ensure that they continue to operate reliably, extend their service life and minimise costly interruptions to production.

Preventive maintenance of hydraulic pumps

Rather than reacting to failures once they have occurred, why not opt for a more proactive approach? preventive maintenance of hydraulic pumps !Would you like to know how? Here are the key steps:

- Draw up a preventive maintenance schedule

Create a detailed schedule specifying the maintenance activities to be carried out and their frequency. Take into account the manufacturer's recommendations, the specific requirements of each pump and the working conditions. This schedule will serve as a guide for planning maintenance activities.

- Carry out regular inspections

Schedule regular inspections to check the general condition of the pump. Look for signs of leaks, component wear, contamination or other potential problems. These inspections can detect problems at an early stage, before they develop into major failures.

- Cleaning and replacing filters

Filters play an essential role in keeping hydraulic fluid clean. Clean filters regularly to remove particles and contaminants. Replace them according to the manufacturer's recommendations or if you notice a significant loss of pressure.

Good filter maintenance helps to extend pump life and prevent blockages.

- Lubricate essential components

Make sure you regularly lubricate critical parts of the pump, such as seals, bearings and gears. Use the lubricants recommended by the manufacturer and respect the recommended lubrication intervals. This will reduce wear and maintain pump performance.

- Monitor operating parameters

Use appropriate pressure gauges and sensors to regularly measure the pressure, flow and temperature of the hydraulic fluid. Compare the measured values with the manufacturer's specifications and watch for abnormal variations. If deviations are detected, identify and correct the underlying cause.

- Keeping a maintenance log

Document all preventive maintenance activities in a logbook. Note the dates of inspections, test results, parts replaced, adjustments made, etc. This allows you to track the maintenance history of each pump, identify trends and make informed decisions.

Corrective maintenance of hydraulic pumps

Although the main aim is to prevent breakdowns through preventive maintenance, it is important to have effective procedures in place to resolve damage quickly when it occurs. So, to ensure curative maintenance of hydraulic pumps, you must :

- Diagnosing the problem

Identify the underlying cause of the hydraulic pump failure. This may involve visual inspections, performance tests, the use of appropriate measuring instruments or even partial dismantling of the pump.

The aim is to understand what caused the fault so that it does not recur in the future.

- Planning repairs

Once the problem has been diagnosed, draw up an action plan to carry out the necessary repairs. This may include ordering spare parts, planning human resources and allocating the time needed for repairs.

- Carrying out repairs

Carry out repairs in accordance with the manufacturer's recommendations and good practice. Make sure you have the technical skills and expertise to carry out repairs properly and safely. If necessary, call in specialist technicians or external service providers.

- Test and check

After repairs, carry out tests to ensure that the hydraulic pump is working properly. Check operating parameters such as pressure, flow and temperature to ensure they are within normal ranges. Carry out performance tests to confirm that the pump is working properly.

- Analysing root causes

Take the opportunity of corrective maintenance to analyse the root causes of the pump failure. Identify the factors that contributed to the problem and determine the corrective measures that need to be put in place to prevent a recurrence in the future. This analysis can provide valuable information for improving the preventive maintenance programme.

- Monitoring and documenting

Make sure you track and document all actions taken during corrective maintenance. This will establish an accurate maintenance history and reference for future maintenance operations. The information gathered can also be used to improve procedures and reinforce preventive maintenance practices.

How do you know if your hydraulic pump is faulty ?

It's important to be aware of the warning signs of hydraulic pump failure so that you can intervene quickly to prevent further damage. To do this, you need to pay attention to certain signs such as :

- Unusual noises

If you hear abnormal noises such as grinding, rattling, excessive vibration or knocking, this may indicate problems with the pump's internal components. This could be due to worn parts, misalignment or lubrication problems.

- Fluid leaks

Hydraulic fluid leaks are often a clear sign of impending failure. Look for leaks in seals, fittings, hoses or connections. Leaks can indicate faulty seals, cracks in components or excessive pressure.

- Loss of performance

If you notice a drop in the performance of the hydraulic pump, such as a reduction in pressure or flow, this may be a sign of problems. This could be due to wear on internal components, deterioration of seals or obstructions in the pipes.

- Increase in temperature

An abnormal rise in the operating temperature of the hydraulic pump may indicate problems such as insufficient lubrication, overloading or deterioration of internal components. High temperatures can lead to rapid component degradation and premature failure.

- Excessive vibration

Excessive vibration may be a sign of imbalance, worn bearings or incorrect alignment of components. Abnormal vibration can damage internal pump components and lead to pump failure.

- Unstable pressure

If hydraulic pressure fluctuates erratically or stabilises at abnormal levels, this may indicate problems in the pump system. Faulty valves, leaks or obstructions can lead to unstable pressure.

- Increased response times

If you notice an increase in the response times of the hydraulic pump, for example a delay in starting or stopping the pump, this may indicate problems with the pump's internal components or controls.

Basically, when you see any of these signs, it's a good idea to carry out a thorough inspection of the pump and carry out any necessary repairs. Early intervention can prevent more serious failures and extend the life of the hydraulic pump.
