How to effectively extend the service life of hydraulic cylinders？
The hydraulic cylinder is equivalent to the core of the hydraulic system. The maintenance of the hydraulic cylinder can effectively extend its service life. Below we will briefly describe how to effectively extend the service life of the hydraulic cylinder from three aspects:
1. Prevent the hydraulic cylinder from rusting
In normal work, the hydraulic piston rod in the hydraulic cylinder cannot be immersed in the oil all the time, it will continuously extend out of the cylinder, and so on. As long as the piston leaves the cylinder and contacts with air, it will definitely be attacked by a series of oxides or acid gases. After a while, these pistons tend to rust easily. If the piston is rusted and repeatedly enters the cylinder, it will also cause the entire hydraulic cylinder to rust. Therefore, to avoid this phenomenon, be sure to coat the piston with an appropriate amount of grease to protect it and reduce the possibility of rusting of the hydraulic cylinder.
2. Change hydraulic oil regularly
After the oil in the hydraulic system has been used for a long time, it is inevitable that other items will enter the oil cylinder, which will make the hydraulic oil cylinder bear more friction during use. In addition, the hydraulic oil also has a specific service life. If the oil is not changed regularly, it will also reduce the working efficiency of the entire hydraulic system and shorten the service life of the hydraulic system.
3. Install the buffer device in the hydraulic cylinder
In the normal operation of the hydraulic cylinder, we need to control the speed of the hydraulic system. If the working speed of the hydraulic system is too fast, exceeding 2m/s, it is very bad for prolonging the service life of the hydraulic cylinder. In this case, it is best to install a buffer device in the hydraulic cylinder, which can not only protect the hydraulic cylinder, but also ensure the safety of the entire hydraulic system.
The maintenance work in the above four aspects has a great impact on the performance, efficiency and life of the hydraulic system. Proper implementation can greatly improve the service life of the hydraulic cylinder.
Besides the above aspects, we also have an important factor as below.
Using high performance materials
Absolutely, if we use high performance materials when manufacturing the hydraulic cylinders, we can greatly improve the performance and durablities of the hydraulic cylinders. Generally, the hydraulic cylinder is consist of hydraulic cylinder barrel, hydraulic piston rods, hydraulic piston, sealing, and cylinder head.
To use high quality steel mother tube for producing the hydraulic cylinder tube, this is because the hydraulic cylinder tube is the main part forming the hydraulic cylinder barrel; and to use higher grade steel rods for the chrome plated rod for hydraulic piston rods; to use high quality performance sealing materials. All these will greatly improve the durability of the hydraulic cylinders.
