Hydraulic systems transmit power efficiently and precisely, which makes them useful in many industries. While regular maintenance, monitoring the system conditions, and using only recommended hydraulic fluids can extend a system’s lifespan and prevent failure, sometimes hydraulic repair is necessary. From the loss of power to unusual noises when operating your hydraulic equipment, there are many signs that tell you it is time to seek hydraulic system repair services.
Reasons Hydraulic Pumps Fail
Hydraulic pumps are an integral component of any hydraulic system. They convert mechanical energy to hydraulic energy, causing fluid movement to power cylinders, motors, and other components of your hydraulic system. While they are designed to be versatile and operate under vigorous conditions, like other system components, they can fail. Discovering a failing hydraulic pump can be challenging. Here are a few examples of when to call expert hydraulic repair services for hydraulic pump failure:
Hydraulic Fluid Contamination
Hydraulic systems work optimally when using a fluid that meets exact specifications. When debris, dirt, and water mix into the hydraulic fluid, they can cause issues inside the pump and damage components. Debris can increase friction, accelerating wear and tear, while water can cause corrosion and decrease viscosity, leading to inefficiencies. Contamination alters the hydraulic fluid’s physical and chemical properties, which causes the pump to work less efficiently and eventually fail.
Extreme temperature changes can affect the viscosity of a hydraulic fluid and, eventually, the performance of your hydraulic system’s pump. Overheating causes the hydraulic fluid to thin, leading to inadequate lubrication, while freezing temperatures increase the viscosity. At this point, cavitation can occur, which is when small cavities of fluid form and implode. When hydraulic fluid doesn’t fill the pump, pressure destabilizes. This can cause excess wear and damage to the hydraulic pump over time.
Overpressurization and Overloading
Different hydraulic pumps are designed to work within a specific pressure range. Excessive load on the pump causes overpressurization, accelerates component wear, and eventually causes the pump to fail. Excess pressure along cavitation can cause an explosion.
Air in the Pump
Hydraulic oil has about 9% dissolved air. Excess air trapped inside the system through unsealed joints and shafts can cause temperature and pressure changes, forcing the pump to work harder. Over time, this can cause the hydraulic pump to break down.
Use of Low-Quality Hydraulic Fluids
Hydraulic systems need high-quality, uncontaminated lubrication and cooling oil to function optimally. The correct fluids for use with hydraulic systems have anti-wear and anti-foam properties and are highly resistant to temperature-related issues. Using fluids other than the recommended can expose your entire hydraulic system to various failure issues. Fluid levels are also integral to the hydraulic system’s performance, so use the recommended amounts.
Get Professional Hydraulic Repair Services
A failing hydraulic pump can quickly bring operations to a halt. If the pump of any of your hydraulic systems is malfunctioning, a team of experienced hydraulic experts can identify and resolve the underlying issue to keep your equipment working smoothly and optimally. Since installation and maintenance errors can exacerbate existing hydraulic issues and result in costly repairs, always remember to check the experience of the team you trust with maintaining your system.
