If you own a hydraulic equipment or you are familiar with the use of cranes, excavators, tractors, or forestry equipment, you must already be aware of the importance of hydraulic pumps, especially when it comes to steering. Hydraulic pumps have been holding an important role in our society since they were invented, as they are nowadays used for multiple purposes. Without the use of such technology as hydraulic pumps it would be impossible to convert mechanical energy into hydraulic energy. This is the reason why you should be aware of how to maintain your hydraulic pump working properly. If you are unsure about how to make your pump operating smoothly, don’t despair! We’ve put together this essential guidelines to make everything easier for you. So keep reading and learning more about the hydraulic pumps topic, so you will be able to ensure their proper maintenance.
You cannot plan to work on a machinery using the system of hydraulic pump for long periods of time without being familiar with the possible hydraulic pump malfunctions and how to fix them. Here are some of the signs you should be checking for before setting them off:
If you hear strange noises coming from anywhere in the machinery of your equipment, you should be checking what’s wrong, as noises are not ideal. When it comes to hydraulic pumps, hearing loud noises is a very obvious sign that something is going wrong. As these kinds of pumps operate fully on fluids, when something is off that oil flow through the pump at extremely high pressure and high speed generates loud noises. Indeed, hydraulic pumps are made to muffle any kind of sound. When some parts of the pump mechanism wear down, chances are you’ll not only experience loud noise but also a worsening in the overall performance, which means that you’ll need to quickly repair or replace the affected part of the mechanism when you hear noises coming from the machine.
Seeing liquids inside the pumps outside the tubes is another clue of something going wrong with your pump. It could be simple as a loose seal or a loose valve or even a more serious reason, especially when the line has a break.
A break might cause the pressure to go lower and also an overall malfunctioning system. As the leak occurs inside the pump, spotting the problem can be a bit of a challenge, meaning that you will need to frequently take a good look at your pump, especially when you are planning to work for longer periods of time, to act on the damage before it’s too late.
If you spot liquids outside the pump, this means that the leaking problem has progressed and you must take action as soon as possible, as outside leaks are signs of the pump being very damaged.
It might be better to ask an expert to assess whether the pump must be replaced or whether it is enough to repair it. To avoid complications, you should frequently check the pump and take action as soon as you identify the problem. Acting early means avoiding the negative chain reaction which will make the entire system fail. Thus, it results in lower maintenance and replacement costs.
Usually, leaking has the effect of reducing both the temperature and the pressure of the system, which has an impact on how viscous the oil is, which lowers the pressure of the system at minimum levels.
High Working Temperatures
If you want your pump to work properly, you must ensure that the right level of fluid viscosity is maintained. Such characteristic of the fluid depends on the pressure and temperature of the pump, which has to fall within the recommended limits. When you notice one of the parameters being different from what it should be, you should immediately take action in order to avoid unnecessary strain to your pump, which will result in you having to replace the pump with a new one.
In particular, you must avoid temperatures over 82 Celsius degrees (F 180) , which indeed harm the pump’s performance. When the system does not cool properly, such temperatures are easily reached. Also, you need to make sure that no obstructions are present in the system reserve area and that the heat exchanger is properly functioning.
Remember that big installations and their complex machinery systems need to have all their parts in an optimal functioning state. To achieve that, you must provide regular maintenance and inspections. Things can break down at a point in time, nevertheless if you work with a professional mechanic, you’ll be able to solve all of your problems rapidly and effectively.
