Funkce

Precise control of damping force: The Safety Valve for Railway Dampers can precisely adjust the flow velocity and volume of the oil inside the rail damper according to different working conditions during high-speed rail operation, thereby generating appropriate damping force. When the vehicle starts, accelerates, decelerates, turns and passes over uneven roads, it can effectively suppress the vibration and shaking of the vehicle body, ensuring the smoothness and comfort řízení vozidla .

Buffering impact loads: During high-speed operation, high-speed rail is subject to various impact loads, such as the impact force generated by track joints and turnouts. The Safety Valves for Train Suspension can instantly buffer these impacts, converting the impact energy into other forms of energy such as the heat energy of the oil, reducing damage to the vehicle structure and equipment, and extending the service life of the vehicle.

Ensuring vehicle stability: By reasonably adjusting the damping force, the valve for shock absorber helps maintain the vehicle's posture stability, preventing excessive tilting or side sway of the body. When a train passes through a curve at high speed, it can keep the vehicle in good lateral stability, ensure that the train travels along the predetermined trajectory, and improve the safety of train operation.

Potíže s výrobou

High-precision processing requirements: The internal structure of the valve for rail damper is complex, containing many precise small holes, channels, valve cores and other components. The processing accuracy requirements for these components are extremely high. For instance, the fit clearance between the valve core and the valve seat usually needs to be controlled within a few microns to tens of microns to ensure the sealing performance of the Valve a jeho přesná schopnost řízení toku . Jakákoli menší chyba zpracování může vést k poklesu výkonu ventilu a ovlivnit celkový účinek tlumiče nárazů .

High-performance material selection and processing: High-speed rail shock absorber valves need to operate under long-term high-speed, high-load and complex environmental conditions, so the performance requirements for materials are very strict. Materials should not only possess high strength and high toughness to withstand huge impact forces and cyclic loads, but also have excellent wear resistance, corrosion resistance and fatigue resistance. In addition, the Proces tepelného zpracování materiálu má také zásadní význam . Je nutné přesně ovládat parametry tepelného zpracování pro získání ideální mikrostruktury a vlastností materiálu .

Complex surface treatment technology: To enhance the wear resistance, corrosion resistance and reduce the coefficient of friction of shock absorber valves, special surface treatment is required. For instance, a high-performance coating is formed on the surface of the valve by methods such as electroplating, electroless plating and spraying. These surface treatment processes require precise control of parameters such as the thickness, uniformity and Přilnavost povlaku, aby se zajistilo, že povlak může udržovat dobrý výkon při dlouhodobém používání .

Přísná kontrola a kontrola kvality: Vzhledem k tomu, že kvalita vysokorychlostních ventilů šoku ve vysokorychlostním železničním šoku přímo souvisí s bezpečností a pohodlí provozu vlaku, musí být stanovena přísná kontrola a kontrolní systém kvality . Během výrobního procesu musí být každá komponenta podrobena i při inspekci v těsnění, přičemž se při inspekci v průběhu musí podrobit více inspekci} {2} { Je nutné provést celkový test výkonu na ventilu tlumiče nárazů, simulovat jeho pracovní podmínky ve skutečném provozu a zajistit, aby všechny jeho ukazatele výkonu splňovaly požadavky na návrh .
