Hydraulic Plough Turn-Over Cylinder
In modern agriculture, efficiency and reliability are paramount. One critical component that ensures optimal performance of ploughing equipment is the hydraulic plough turn-over cylinder, or ram. This article explores the features, benefits, and best practices associated with hydraulic plough turn-over cylinders, focusing on their importance in enhancing agricultural productivity.
Key Features of Hydraulic Plough Turn-Over Cylinders
Maximum Working Pressure
Hydraulic plough turn-over cylinders are designed to operate at a maximum working pressure of 200 bar, ensuring they can handle demanding agricultural tasks with ease. This high-pressure capability allows for robust performance, even in challenging conditions.
Maximum Testing Pressure
The cylinders are tested at pressures up to 300 bar, providing an added layer of safety and reliability. This rigorous testing ensures that the cylinders can withstand extreme conditions and perform reliably under maximum loads.
Maximum Working Speed
With a working speed of up to 0.5 meters per second, these cylinders offer efficient and rapid movement. This speed is crucial for reducing downtime and increasing the overall efficiency of ploughing operations.
Temperature Range
The cylinders are built to function in a wide range of temperatures, from -30 ºC to +90 ºC. This adaptability makes them suitable for various climates and ensures consistent performance throughout the year.
High-Quality Materials
Rod
Made from chrome-plated steel F-1140, the rod has a minimum chrome layer thickness of 20 microns, ensuring durability and resistance to wear. With a minimum surface hardness of 900 HV and corrosion resistance for at least 200 hours in neutral saline fog (ISO9227 rating 9), the rod is built to last.
Tube
Constructed from steel ST-52-3, DIN 2393, the tube has an inside diameter tolerance of ISO H9 and a roughness of Ra < 0.8 microns. This precision engineering guarantees smooth operation and longevity.
Guide-Bushing
Made from steel F-1140 and nitrited for added hardness, the guide-bushing ensures robust performance.
Piston
Also made from steel F-1140, the piston is designed for high durability and reliability.
Advanced Sealing Systems
Guide-Bushing Seals
Dynamic: Compact polyurethane rod-seal with double lips and an NBR metal wiper seal.
Static: NBR 90 shore O-ring.
Piston Seals
Dynamic: Compact double-acting polyurethane seal with a nitrile O-ring activator and special polyacetal guides reinforced with glass fiber.
Static: Polyamide locking sealing guide.
These advanced sealing systems prevent leaks and ensure the cylinder operates smoothly and efficiently, reducing maintenance needs and extending the lifespan of the equipment.
Finishing and Protection
The cylinders are finished with black prime painting, providing a layer of protection against environmental factors and enhancing their durability.
Best Practices for Using Hydraulic Plough Turn-Over Cylinders
Use a Relief Valve
Protect the cylinder circuit with a relief valve set at 200 bar to prevent overpressure and potential damage.
Maintain Oil Cleanliness
Check the oil cleanliness regularly and use filters to prevent contamination. Clean oil ensures smooth operation and extends the cylinder’s lifespan.
Proper Installation
Bleed the circuit by slightly loosening the cylinder fittings before starting up. Avoid welding on the cylinder tube, and if welding on the rod or bottom is necessary, dismount the cylinder first.
Storage and Protection
For long-term storage, avoid outdoor conditions if possible. If outdoor storage is unavoidable, keep the rod fully retracted or apply grease to protect it. During high-pressure cleaning or blasting, ensure the rod and oil ports are suitably protected.
Special Considerations for Single-Acting Cylinders
When using double-acting cylinders as single-acting, connect the unused oil port to the tank.
Reassembly Precautions
If dismounting the cylinder, note that the piston is screwed onto the rod end and fixed with industrial glue. Use industrial glue when reassembling to ensure a secure fit.
Hydraulic plough turn-over cylinders are essential components in modern agricultural machinery, providing the power, speed, and reliability needed for efficient ploughing operations. By understanding their features and following best practices, farmers and equipment operators can maximize the performance and longevity of these vital hydraulic components. Investing in high-quality hydraulic cylinders not only enhances productivity but also ensures the smooth and efficient functioning of ploughing equipment, ultimately contributing to greater agricultural success.
