Replacing seals in the hydraulic cylinder of the lift - step by step
Seals play a very important function in every hydraulic cylinder. Over time, they may wear out and therefore need to be replaced. How to properly install seals in hydraulic cylinders? What is worth remembering? Learn the step-by-step process of replacing seals.
Choosing the right seal in the actuator
The first step during replacing seals in the actuator lift is to select the appropriate component. You need to take into account the type and size of the seal, as well as the materials from which it is made. It must be matched to the specific type of oil and hydraulic fluids used in a given boom. It is also important that the seal is adapted to the operating conditions of the actuator. The seal must also be sufficiently flexible and durable. It should match the specific type of tensioner and other mounting elements used in the actuator. To avoid mistakes in this field, it is best to choose original parts intended for specific brands and models of lifts.
Replacing seals in the actuator step by step
Replacing hydraulic cylinder seals should run according to a specific order.
- Disconnect the actuator from the remaining elements of the hydraulic system.
- Unscrew the mounting screws.
- Remove the old cylinder seals and remove the bushings.
- Clean the removed elements from any deposits.
- Place the new actuator seals in place. Make sure they fit properly onto the sleeve surface.
- Reinstall the bushings in the actuator and secure them with the screws.
- Make sure that the connection between individual elements is tight - there must be no leakage of oil or other hydraulic fluids in the system.
- Reconnect the actuator to the hydraulic system. Run it according to the machine manufacturer's recommendations.
How often should seals in the actuator be replaced?
The seals in the actuator should be replaced regularly. It is worth doing such work even if the previous seal is not completely worn out. In this way, you can prevent damage to other parts of the system, which are usually very expensive to repair.
More frequent replacement of actuator seals should take place for lifts used in difficult conditionssuch as heavy load, high pressure, extreme temperatures or frequent duty cycles. These factors may shorten the life of the seals.
Can I replace hydraulic cylinder seals myself?
Replacing seals hydraulic cylinder it's not complicated. However, it requires knowledge about the femur of a specific device and safety rules during repair. For this reason, such tasks should be handled by trained technicians. Many companies have people designated for this purpose. It is also possible to take the machine to a professional workshop, whose employees will replace the seals in the actuator for a fee.
What should you remember when replacing seals in the actuator?
To replace the actuator seals, you need tools that will allow you to safely dismantle individual elements. It's important too analyzing the technical documentation of a specific machine and her disconnection from the energy source before starting work.
It also turns out to be extremely important performing tests after the replacement. Make sure that the seal is installed correctly and fits perfectly to the actuator. Otherwise, after reassembling the system, operating fluid leaks may occur and, as a consequence, important components of the device may be damaged.
What signals indicate the need to replace seals in the actuator?
If the seals in the hydraulic system have not been replaced early enough, disturbing signals may appear. This is mainly about oil leaks and/ or hydraulic fluid - both internal and external. This is also a disturbing symptom changing the way the actuator works – instability, noise or difficulty moving.
The better solution is planning replacing seals in the actuatorbefore the mentioned faults occur. This helps prevent damage to other parts of the system.
Regular maintenance of cylinder seals
It is worth carrying out regular servicing of the actuator, which includes, among others: checking the condition of sealants. If during routine inspections If you notice signs of wear, aging materials or other potential problems, you should consider replacing the components. This solution allows you to reduce the costs incurred in connection with repairs.
