Hydraulic Repairs Services

Hydraulic Repairs make up the bundled processes of diagnosing, servicing and finally rectifying any and all issues within hydraulic components and/or systems. Over time, hydraulic components face wear and tear, and this damage spreads throughout the system.

The hydraulic repairs process involves taking apart and thorough examination of the hydraulic components in question, whether that be a hydraulic ram, hydraulic cylinders etc. Then, there will be an identification of the problem, followed by a thorough cleaning, repair and reassembly of parts.

Hydraulic pumps are a crucial component in hydraulic systems. They convert mechanical energy from power sources into hydraulic energy by generating a sufficient flow to overcome pressure caused by the load. When the pump achieves this, they’ve achieved its role in hydraulic system design.

Hydraulic pumps are vital components and you should call for hydraulic repairs if one ever becomes faulty.

These are some of the signs of faulty hydraulic pumps:

• Excessive Noise or Vibration
• Decreased Performance
• Overheating
• Leaking Fluid
• Irregular Fluid Flow
• Increased Energy Consumption

Hydraulic motor machinery is mechanical actuators that convert hydraulic or fluid energy into rotary motion. They are not to be confused with a hydraulic cylinder, which converts energy into a linear motion.

Call for hydraulic repairs when you notice the following:

1. Loss of Power
2. Abnormal Noises
3. Overheating
4. Leaks
5. Irregular Movement

A hydraulic pump and motor are two key components in a hydraulic system, and while they operate based on similar principles, they have distinct functions.

1. Hydraulic Pump: The primary function of a hydraulic pump is to convert mechanical energy (like from an electric motor or engine) into hydraulic energy by generating flow. This means it takes in a volume of fluid from a reservoir at low pressure and sends it to the hydraulic system at a higher pressure. The high-pressure fluid can then be used to perform work in the system, like moving an actuator.
2. Hydraulic Motor: On the other hand, a hydraulic motor is a type of actuator that converts hydraulic energy back into mechanical energy. It takes in high-pressure fluid from the system, which causes it to rotate, and this rotational movement can be used to perform work, like driving wheels or a conveyor belt.

A hydraulic pump and motor differ due to pumps supplying the hydraulic fluid under pressure and hydraulic motors use that fluid to create motion. Although they are built similarly and operate based on similar principles, their roles in a hydraulic system are opposite to each other. Nonetheless, CJ Plant provides excellent service on both hydraulic pump and motor repair.

Maintaining your hydraulic motors is a matter of scheduling regular checks.

Hydraulic fluid checks: Regularly test the hydraulic fluid levels and maintain a proper level that is clear of contamination. Sample the fluid for any changes in colour and odour. If the water takes on a milky hue, then it may be contaminated.

Change the filters: Filters keep pollutants that will lead to some of the more common failures of a hydraulic motor. Considering it’s not easy to spot contamination when you see it, it may be a good idea to simply have filters on hand and schedule their changing.

Replace seals: Seals are responsible for keeping the motor from leaking. Over time they will degrade, especially if contamination has been in your motor for any period of time.

Hoses and fittings: All hoses and fittings should be checked for damage. This could be from fraying, stretching and kink. Anything with dents, or signs of corrosion, needs to be replaced. On top of that, ensure couplers are clean and secure any fittings that can be.

The temperature needs to be regulated within a motor to ensure its smooth function, and to avoid the following: 

Fluid Thickening – Viscosity is the resistance a liquid has to parting from itself. For example, when water gathers on a ceiling and drips slowly. This is gravity pulling away water. Low temperatures can increase the resistance of the hydraulic oil within the pump, leading not only to productivity issues but also to cavitation. 

Fluid Thinning: Meeting a certain heat threshold can cause a motor’s fluid to thin. This makes lubrication difficult, and it also makes escape in the form of leaks much easier. 

Fluid Oxidisation: Oxidisation is the process of a substance being mixed with oxygen. Whilst heat can cause fluid to thin, as explained in the last example, extreme heat can cause oxidisation, thereby thickening the fluid. Sometimes it becomes so thick that it blocks the flow of water, which also causes a buildup of heat due to the motor’s inability to dissipate and regulate its own temperature. 

Both air and water can pollute a hydraulic motor. The following are the three different types of contamination that can destroy a piece of machinery. 

Cavitation is the process of the separation and implosion of the dissolved air within hydraulic oil. The implosion results not only in a distinct whining sound but also causes damage to the pump over a period of time. This damage can also spread to other components within the motor. 

Aeration is the process of air invading the motor from the outside. This is almost always due to some sort of structural damage on the motor, such as loose connections, or even a leak. The contamination makes a knocking sound. 

Water Contamination is a fairly basic process. It relies on there already being structural damage to the machine. If the water receives too much oxygen (oxidation) or falls in temperature to the point of freezing, it will degrade the inner components of the motor over time. The fluid will then take on a milk-like look.
