The Sany 335/365 distribution valve is a crucial component in the hydraulic system of excavators produced by Sany Heavy Industry. It is used to control the flow direction of hydraulic oil, enabling various movements of the excavator. Below is a detailed introduction to the Sany 335/365 distribution valve:
I. Functions and Roles
The distribution valve plays a vital role in the excavator's hydraulic system. By altering the flow direction of hydraulic oil, it controls actions such as the lifting and lowering of the boom cylinder, as well as the tilting up and down of the bucket cylinder, thereby facilitating the excavator's digging, loading, lifting, and other operational functions.
II. Structure and Composition
The Sany 335/365 distribution valve typically consists of multiple valve stems, a valve body, safety valves, overload makeup valves, and other components. These parts work together to ensure the stable and reliable operation of the hydraulic system. Specifically:
• Valve Stems: Used to control the flow direction of hydraulic oil, enabling various movements of the excavator.
• Valve Body: As the main part of the distribution valve, it withstands the pressure and flow of hydraulic oil, ensuring the flexible movement of the valve stems.
• Safety Valves: Used to regulate the pressure of hydraulic oil, preventing damage to components due to excessive system pressure.
• Overload Makeup Valves: Automatically supply additional oil when the hydraulic system is overloaded, protecting the system from damage.
III. Performance Characteristics
The Sany 335/365 distribution valve has the following performance characteristics:
• High Reliability: Manufactured using high-quality materials and advanced processes, ensuring stable operation even in harsh working environments.
• High Efficiency: Optimized design reduces the flow resistance of hydraulic oil, improving the transmission efficiency of the system.
• Easy Maintenance: The reasonable structural design of the distribution valve facilitates disassembly and repair, reducing maintenance costs and time.
IV. Application Scenarios
The Sany 335/365 distribution valve is widely used in excavators of models 335 and 365 produced by Sany Heavy Industry. These excavators play important roles in construction, mining, ports, and other settings, and the distribution valve, as a core component of their hydraulic systems, has a crucial impact on the performance and stability of the excavators.
V. Repair and Maintenance
To ensure the normal operation and extend the service life of the Sany 335/365 distribution valve, regular repair and maintenance are required. This includes:
• Regular Inspection: Periodically inspect the tightness of the distribution valve, the flexibility of the valve stems, and the regulated pressure of the safety valves to ensure all performance indicators meet requirements.
• Cleaning and Maintenance: Regularly clean oil stains and impurities from the surface of the distribution valve to prevent them from entering the hydraulic system and causing damage.
• Replacement of Wear Parts: Timely replace severely worn valve stems, seals, and other wear parts to ensure the normal operation of the distribution valve.
