How to prevent your hydraulic
system from leaking oil with
servo valve repair maintenance
The main downside of a hydraulic system is that it can be messy. Most of the factories that operate hydraulic systems deal with constant oil leaks. For some manufacturers it becomes a deal breaker. For instance, medical, food packaging and chemical factories, try to stay away from hydraulics simply because oil spill can possibly contaminate the production area. Even though leaks are a major issue, they can be easily avoided if maintenance is done properly.
There Are Many Cases of Servo Valve Repair Failures in Hydraulic Systems
Hydraulics systems have a lot of advantages when comparing to other systems, such as electrical. For example: fast speed and instant pressure. In addition to that hydraulics can be very energy efficient, especially when using Servo Valves. One of the reasons is that it is fairly simple in comparison to electric systems. It is simple to start and stop the movement with valves and levers. Modern Hydraulic systems that are operated through Servo Valves can provide fast and smooth acceleration and deceleration. Since it is a fluid system, it is easier to direct movement via cylinders then it is through a set of gears and belts. Hydraulics system also provide a benefit of moving large weight fairly easy. Hydraulic systems are more economical since they don’t require large amounts of components that are involved in the movement of axis.
Below are common things to look at when preventing oil leaks in your hydraulic systems to help practice proper
preventative maintenance to avoid costly Servo Valve repair.
The proper torque has to be applied when tightening bolts, nuts and fittings.
Most of the people do not pay enough attention to proper torques when dealing with hydraulic systems. It is important to use torque wrenches when tightening components of hydraulic systems. In Elite servo, we use torque wrenches when mounting Servo Valves on our test benches, to make sure we are not damaging the equipment.
When there is not enough torque applied on the bolts, the oil starting to deteriorate O-rings and cause leaks. O-rings are crucial component to all Servo Valves and other components of hydraulic circuit. Deteriorated O-rings can get into hydraulic system and cause issues: such as prevent proper spool movement within a Servo Valve.
Applying too much torque on the bolts can warp the body of the Servo Valve and make spool stick.
O-rings deteriorate with time, even if proper torque applied. It is important to dedicate time toward maintenance and replace all the worn-out O-rings within hydraulic system. It is necessary to use proper size of the O-rings. Majority of the Servo Valve manufacturers such as Bosch, Rexroth, and Moog use metric O-rings. Maintenance department should have an inventory of O-rings for all the sizes that are used in the hydraulic system.
Inspection of hydraulic hoses and fittings.
It is important to check all the hoses and fittings for wear. Raptured hose can make a huge mess and create a lot of problems in the manufacturing facility. All the hoses and fittings that are starting to wear out should be immediately replaced to prevent further damage.
Properly tuneyourhydraulic system.
There are some causes of hydraulic leaks such as hydraulic shock. If your hydraulic system is not tuned properly, your equipment will be experiencing overloads of hydraulic pressure that can cause major damage. At Elite Servo, we understand the importance of properly tuning our repairs. We use OEM test sheets to make sure that all of our repairs perform exactly how they did when they were brand new.
