What is Reach Stacker Seal Kits
The reach stacker seal kits are a sealing device used to protect the reach stacker hydraulic cylinder. Its main function is to prevent hydraulic oil from leaking and external impurities from entering the hydraulic system. The sealing kit is usually made of high-performance wear-resistant materials, such as polytetrafluoroethylene (PTFE) or other polymer materials, to provide good durability and sealing performance. It is installed in key parts of the machine, such as bearings, oil seals transmission shafts, etc., to form a closed space to block the entry of pollutants in the external environment.
Sealing principle
The sealing kit of the reach stacker mainly uses lip seal rings for sealing. The working principle of this sealing ring is to use the close fit between its lip and the shaft to achieve the sealing effect. When the sealing ring is installed on the seal seat, its lip will be stretched due to the rotation of the shaft, forming an oil sealing ring to block the oil and prevent it from leaking. At the same time, the lip will also generate a certain amount of friction on the surface of the shaft, helping the lip seal maintain a stable position and fit.
In addition to lip seals, some sealing kits use O-rings, piston rings, and other sealing elements, and their sealing principles are also different. O-rings usually use the elasticity and compressibility of rubber to form a certain sealing pressure in the sealing groove, thereby achieving the effect of preventing leakage. The piston ring uses the hardness and elasticity of the metal material to form a tight fit in the cylinder liner to prevent gas leakage.
In short, the function of the sealing kit is to prevent liquid or gas from leaking from the machinery, thereby ensuring the normal operation and safety of the machinery. Different types of sealing elements have different sealing principles and application ranges. Appropriate sealing elements need to be selected according to the specific use environment and requirements.
Installation
1. Preparation: Before installation, make sure you have the correct reach stacker seal kits and check whether they are intact. Also, make sure you have the proper tools and equipment, as well as safety measures.
2. Shutdown and power outage: Before performing any installation work, ensure that the reach stacker has been shut down and powered off. This is to avoid any accidental injury and mechanical failure.
3. Disassemble the old sealing kit: If you need to replace the old sealing kit, you need to disassemble it first. Depending on the specific mechanism and seal package design, it may be necessary to remove some parts or loosen the fastening bolts.
4. Cleaning and Preparation: Before installing a new sealing kit, it is important to clean and prepare the sealing area. Be sure to remove dirt and residue from and around the old seal kit to ensure the new seal kit will fit and seal properly.
5. Install the new seal kit: According to the design and installation requirements of reach stacker seal kits, install the new seal elements to the corresponding positions of the mechanical devices one by one. Proper tools and techniques may be required to ensure that sealing elements are installed correctly and adjusted and tightened as necessary.
6. Inspection and testing: After completing the installation of the seal kit, perform inspection and testing to ensure that it is working properly. Check for any leaks or loose parts to make sure the seal is good.
7. Start-up and operation: After confirming that the sealing kit is installed correctly and working properly, restart the reach stacker and perform a test operation. Monitor its operation and ensure seal kit performance and durability.
precautions for product use
Pre-installation inspection: Before installing reach stacker seal kits, be sure to carefully check their integrity and adaptability. Make sure the size, material, and type of sealing kit are suitable for the reach stacker requirements.
Cleaning work: Cleaning work is very important before installing the sealing kit. Make sure the surfaces of the relevant parts are clean and free of dust, grease, or other impurities to ensure the sealing kit will fit snugly and perform optimally.
Correct installation: Follow the installation guidelines provided by the reach stacker manufacturer. Make sure the sealing kit is placed correctly and is properly secured and sealed as directed.
Maintenance: Maintenance of reach stacker seal kits is very important to ensure their long-term effectiveness. Regularly check the seal kit for wear and, if necessary, replace severely worn seals to prevent leakage and performance degradation.
Avoid excessive stress: The sealing kit of the reach stacker should be protected from excessive stress during use. Avoid excessive shock, vibration, or torque that may damage the sealing assembly.
Temperature and chemicals: Sealing kits may be exposed to varying temperatures and chemicals. Make sure the sealing kit can withstand temperature changes and chemicals in its environment.
Quality Inspection
1. Appearance inspection: The automatic quality inspection machine can check the appearance of the sealing kit, including surface flatness, color, shape, etc., to ensure that there are no obvious defects or damage to meet the ppm requirements for appearance.
2. Dimensional measurement: Use a 2.5D projector, 3D projector, pycnometer, and other measuring tools to measure the size and geometric parameters of the sealing kit, such as diameter, width, height, etc., and compare with the specification requirements.
3. Material inspection: Inspect the materials used in the sealing kit. This may include using an infrared spectrometer to confirm the composition of the material and conducting tensile testing machines for physical property testing.
4. Sealing performance test: Install the sealing kit on the corresponding equipment or test fixture, and conduct the sealing performance test. This can include pressure testing, vacuum testing, or liquid seal performance testing to ensure the seal kit performs as required under actual use conditions.
5. Durability and wear resistance test: simulate the durability and wear resistance of the sealing kit under actual use conditions. This may include conducting cyclic testing, vibration testing, or friction and wear testing to evaluate the longevity and performance stability of the seal package.
6. Temperature and chemical resistance testing: Test the performance of the sealing kit under different temperature conditions, as well as its resistance to common chemicals (such as oil, solvents, etc.). This can be accomplished by subjecting the seal kit to a harsh environment or performing specific laboratory testing.
