Recently, Guangxi Liuzhou Guoji Industrial Co., Ltd. launched the new series of solenoid valve injectors for the leading brand DH-020A series gasoline engine, which has attracted extensive attention from industry experts and domestic automobile manufacturers. Over the years, China's vehicle manufacturers have been relying on imports because EFI technology has been monopolized by a few companies in developed countries. As the most important actuator in automotive electronic fuel injection systems, injectors are compared to the “core†of the EFI system. The emission of pollutants from automobiles and motorcycles must reach the current emission standards in China. The important technical means is to use the electronically controlled fuel injection system upgrade. In recent years, Liuzhou Guoji Industrial Co., Ltd. has worked hard to develop a fuel injector manufacturing technology system with completely independent intellectual property rights, which fills domestic gaps, breaks the technological monopoly of developed countries, and truly realizes all auto parts in China. Localization has provided reliable technical support for Chinese cars carrying the Chinese "core." The Industrial Machinery Internal Combustion Engine Product Quality Supervision and Testing Center (Tianjin) determined that the integrated performance of the leading-brand gasoline engine electromagnetic valve injector manufactured by Liuzhou Guoji Industry Co., Ltd. has completely reached the technical level of similar international products. According to reports, Liuzhou Guoji Industrial Co., Ltd.'s EFI technology products have achieved industrial production. The injector not only obtained national invention patents, but more importantly, it integrated its product technical standards, measurement methods, design, technology and manufacturing into a complete manufacturing system, and developed special injector production and testing equipment. The country's first solenoid valve injector special laboratory and injector professional production line. Excavator Cylinder Piston Rod Seals

The installation and application of hydraulic cylinder piston rod seals in excavators mainly include the following aspects:
1. Applying lubricating oil: Before installing the seal, the surface of the piston rod must be coated with lubricating oil to facilitate the installation and use of the seal.
2. Install the seal: Install the seal on the piston rod in sequence, taking care not to pinch or bend the seal.
3. Pressing the seal: After installing the seal, special tools need to be used to press the seal tightly to ensure its tightness and stability.
4. Check the sealing effect: After installing the sealing element, it is necessary to check the sealing effect. It can be detected by observing the working status of the hydraulic cylinder or using tools such as leak detectors.
5. Application scenario: The piston rod seal of excavator hydraulic cylinder is mainly used in the hydraulic system of construction machinery such as excavators, loaders, and bulldozers to prevent hydraulic oil leakage and ensure the normal operation of the machine.
In summary, the installation and application of hydraulic cylinder piston rod seals in excavators is a very important part of the hydraulic system, and must be strictly operated in accordance with regulations to ensure the normal operation and safety of the machine.
